• Acute myocardial infarction (AMI)
• Acute coronary syndrome
• Coronary thrombosis
• Coronary occlusion

A heart attack happens when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can’t get oxygen. If blood flow isn’t restored quickly, the section of heart muscle begins to die.

Heart attack treatment works best when it’s given right after symptoms occur. If you think you or someone else is having a heart attack, even if you’re not sure, call 9–1–1 right away.

Heart attacks most often occur as a result of ischemic heart disease, also called coronary heart disease or coronary artery disease. Ischemic heart disease is a condition in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart.

When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.

Eventually, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque’s surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.

If the blockage isn’t treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.

Heart With Muscle Damage and a Blocked Artery

A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery. Spasms can occur in coronary arteries that aren’t affected by atherosclerosis.

Heart attacks can be associated with or lead to severe health problems, such as heart failure and life-threatening arrhythmias.

Heart failure is a condition in which the heart can’t pump enough blood to meet the body’s needs. Arrhythmias are irregular heartbeats. Ventricular fibrillation is a life-threatening arrhythmia that can cause death if not treated right away.

Don’t Wait – Get Help Quickly

Acting fast at the first sign of heart attack symptoms can save your life and limit damage to your heart. Treatment works best when it’s given right after symptoms occur.

Many people aren’t sure what’s wrong when they are having symptoms of a heart attack. Some of the most common warning symptoms of a heart attack for both men and women are:

• Chest pain or discomfort. Most heart attacks involve discomfort in the center or left side of the chest. The discomfort usually lasts more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, or pain. It also can feel like heartburn or indigestion.
• Upper body discomfort. You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach (above the belly button).
• Shortness of breath. This may be your only symptom, or it may occur before or along with chest pain or discomfort. It can occur when you are resting or doing a little bit of physical activity.

Other possible symptoms of a heart attack include:

• Breaking out in a cold sweat
• Feeling unusually tired for no reason, sometimes for days (especially if you are a woman)
• Nausea (feeling sick to the stomach) and vomiting
• Light-headedness or sudden dizziness
• Any sudden, new symptom or a change in the pattern of symptoms you already have (for example, if your symptoms become stronger or last longer than usual)

Not all heart attacks begin with the sudden, crushing chest pain that often is shown on TV or in the movies, or other common symptoms such as chest discomfort. The symptoms of a heart attack can vary from person to person. Some people can have few symptoms and are surprised to learn they’ve had a heart attack. If you’ve already had a heart attack, your symptoms may not be the same for another one. 

Quick Action Can Save Your Life: Call 9–1–1

If you think you or someone else may be having heart attack symptoms or a heart attack, don’t ignore it or feel embarrassed to call for help. Call 9–1–1 for emergency medical care. Acting fast can save your life.

Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. Take a nitroglycerin pill if your doctor has prescribed this type of treatment.

What causes a Heart Attack

Coronary Heart Disease

A heart attack happens if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can’t get oxygen. Most heart attacks occur as a result of ischemic heart disease.

Ischemic heart disease is a condition in which a waxy substance called plaque builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to your heart.

When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.

Eventually, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque’s surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.

If the blockage isn’t treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.

Coronary Artery Spasm

A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery. Spasms can occur in coronary arteries that aren’t affected by atherosclerosis.

What causes a coronary artery to spasm isn’t always clear. A spasm may be related to:

• Taking certain drugs, such as cocaine
• Emotional stress or pain
• Exposure to extreme cold
• Cigarette smoking

Risk Factors

Certain risk factors make it more likely that you’ll develop ischemic heart disease and have a heart attack. You can control many of these risk factors.

Risk Factors You Can Control

The major risk factors for a heart attack that you can control include:

• Smoking
• High blood pressure
• High blood cholesterol
• Overweight and obesity
• An unhealthy diet (for example, a diet high in saturated fat, trans fat, cholesterol, and sodium)
• Lack of routine physical activity
• High blood sugar due to insulin resistance or diabetes

Some of these risk factors—such as obesity, high blood pressure, and high blood sugar—tend to occur together. When they do, it’s called metabolic syndrome.

In general, a person who has metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone who doesn’t have metabolic syndrome.

Risk Factors You Can’t Control

Risk factors that you can’t control include:

• Age. The risk of heart disease increases for men after age 45 and for women after age 55 (or after menopause).
• Family history of early heart disease. Your risk increases if your father or a brother was diagnosed with heart disease before 55 years of age, or if your mother or a sister was diagnosed with heart disease before 65 years of age.
• Preeclampsia (pre-e-KLAMP-se-ah). This condition can develop during pregnancy. The two main signs of preeclampsia are a rise in blood pressure and excess protein in the urine. Preeclampsia is linked to an increased lifetime risk of heart disease, including CHD, heart attack, heart failure, and high blood pressure.

Signs, Symptoms, and Complications

Not all heart attacks begin with the sudden, crushing chest pain that often is shown on TV or in the movies. In one study, for example, one-third of the patients who had heart attacks had no chest pain. These patients were more likely to be older, female, or diabetic.

The symptoms of a heart attack can vary from person to person. Some people can have few symptoms and are surprised to learn they’ve had a heart attack. If you’ve already had a heart attack, your symptoms may not be the same for another one. It is important for you to know the most common symptoms of a heart attack and also remember these facts:

• Heart attacks can start slowly and cause only mild pain or discomfort. Symptoms can be mild or more intense and sudden. Symptoms also may come and go over several hours.
• People who have high blood sugar (diabetes) may have no symptoms or very mild ones.
• The most common symptom, in both men and women, is chest pain or discomfort.
• Women are somewhat more likely to have shortness of breath, nausea and vomiting, unusual tiredness (sometimes for days), and pain in the back, shoulders, and jaw.

Some people don’t have symptoms at all. Heart attacks that occur without any symptoms or with very mild symptoms are called silent heart attacks.

Most Common Symptoms

The most common warning symptoms of a heart attack for both men and women are:

• Chest pain or discomfort. Most heart attacks involve discomfort in the center or left side of the chest. The discomfort usually lasts for more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, or pain. It also can feel like heartburn or indigestion. The feeling can be mild or severe.
• Upper body discomfort. You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach (above the belly button).
• Shortness of breath. This may be your only symptom, or it may occur before or along with chest pain or discomfort. It can occur when you are resting or doing a little bit of physical activity.

The symptoms of angina can be similar to the symptoms of a heart attack. Angina is chest pain that occurs in people who have ischemic heart disease, usually when they’re active. Angina pain usually lasts for only a few minutes and goes away with rest.

Chest pain or discomfort that doesn’t go away or changes from its usual pattern (for example, occurs more often or while you’re resting) can be a sign of a heart attack.

All chest pain should be checked by a doctor.

Other Common Signs and Symptoms

Pay attention to these other possible symptoms of a heart attack:

• Breaking out in a cold sweat
• Feeling unusually tired for no reason, sometimes for days (especially if you are a woman)
• Nausea (feeling sick to the stomach) and vomiting
• Light-headedness or sudden dizziness
• Any sudden, new symptoms or a change in the pattern of symptoms you already have (for example, if your symptoms become stronger or last longer than usual)

Not everyone having a heart attack has typical symptoms. If you’ve already had a heart attack, your symptoms may not be the same for another one. However, some people may have a pattern of symptoms that recur.

The more signs and symptoms you have, the more likely it is that you’re having a heart attack.

Quick Action Can Save Your Life: Call 9–1–1 

The signs and symptoms of a heart attack can develop suddenly. However, they also can develop slowly—sometimes within hours, days, or weeks of a heart attack.

Any time you think you might be having heart attack symptoms or a heart attack, don’t ignore it or feel embarrassed to call for help. Call 9–1–1 for emergency medical care, even if you are not sure whether you’re having a heart attack. Here’s why:

• Acting fast can save your life.
• An ambulance is the best and safest way to get to the hospital. Emergency medical services (EMS) personnel can check how you are doing and start life-saving medicines and other treatments right away. People who arrive by ambulance often receive faster treatment at the hospital. 
• The 9–1–1 operator or EMS technician can give you advice. You might be told to crush or chew an aspirin if you’re not allergic, unless there is a medical reason for you not to take one. Aspirin taken during a heart attack can limit the damage to your heart and save your life.

Diagnosing a Heart Attack

Your doctor will diagnose a heart attack based on your signs and symptoms, your medical and family histories, and test results.

Diagnostic Tests

EKG (Electrocardiogram)

An EKG is a simple, painless test that detects and records the heart’s electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through each part of the heart.

An EKG can show signs of heart damage due to ischemic heart disease and signs of a previous or current heart attack.

Blood Tests

During a heart attack, heart muscle cells die and release proteins into the bloodstream. Blood tests can measure the amount of these proteins in the bloodstream. Higher than normal levels of these proteins suggest a heart attack.

Commonly used blood tests include troponin tests, CK or CK–MB tests, and serum myoglobin tests. Blood tests often are repeated to check for changes over time.

Coronary Angiography

Coronary angiography is a test that uses dye and special x rays to show the insides of your coronary arteries. This test often is done during a heart attack to help find blockages in the coronary arteries.

To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization.

A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream.

Special x rays are taken while the dye is flowing through the coronary arteries. The dye lets your doctor study the flow of blood through the heart and blood vessels.

If your doctor finds a blockage, he or she may recommend a procedure called percutaneous coronary intervention (PCI), sometimes referred to as coronary angioplasty. This procedure can help restore blood flow through a blocked artery. Sometimes a small mesh tube called a stent is placed in the artery to help prevent blockages after the procedure.

Treatment

Early treatment for a heart attack can prevent or limit damage to the heart muscle. Acting fast, by calling 9–1–1 at the first symptoms of a heart attack, can save your life. Medical personnel can begin diagnosis and treatment even before you get to the hospital.

Immediate Treatment

Certain treatments usually are started right away if a heart attack is suspected, even before the diagnosis is confirmed. These include:

• Aspirin to prevent further blood clotting
• Nitroglycerin to reduce your heart’s workload and improve blood flow through the coronary arteries
• Oxygen therapy
• Treatment for chest pain

Once the diagnosis of a heart attack is confirmed or strongly suspected, doctors start treatments promptly to try to restore blood flow through the blood vessels supplying the heart. The two main treatments are clot-busting medicines and percutaneous coronary intervention, also known as coronary angioplasty, a procedure used to open blocked coronary arteries.

Clot-Busting Medicines

Thrombolytic medicines, also called clot busters, are used to dissolve blood clots that are blocking the coronary arteries. To work best, these medicines must be given within several hours of the start of heart attack symptoms. Ideally, the medicine should be given as soon as possible.

Percutaneous Coronary Intervention

Percutaneous coronary intervention is a nonsurgical procedure that opens blocked or narrowed coronary arteries. A thin, flexible tube (catheter) with a balloon or other device on the end is threaded through a blood vessel, usually in the groin (upper thigh), to the narrowed or blocked coronary artery. Once in place, the balloon located at the tip of the catheter is inflated to compress the plaque and related clot against the wall of the artery.

This restores blood flow through the artery. During the procedure, the doctor may put a small mesh tube called a stent in the artery. The stent helps to keep the blood vessel open to prevent blockages in the artery in the months or years after the procedure.

Other Treatments for Heart Attack

Other treatments for heart attack include:

• Medicines
• Medical procedures
• Heart-healthy lifestyle changes
• Cardiac rehabilitation

Medicines

Your doctor may prescribe one or more of the following medicines.

• ACE inhibitors. ACE inhibitors lower blood pressure and reduce strain on your heart. They also help slow down further weakening of the heart muscle.
• Anticlotting medicines. Anticlotting medicines stop platelets from clumping together and forming unwanted blood clots. Examples of anticlotting medicines include aspirin and clopidogrel.
• Anticoagulants. Anticoagulants, or blood thinners, prevent blood clots from forming in your arteries. These medicines also keep existing clots from getting larger.
• Beta blockers. Beta blockers decrease your heart’s workload. These medicines also are used to relieve chest pain and discomfort and to help prevent another heart attack. Beta blockers also are used to treat arrhythmias (irregular heartbeats).
• Statin medicines. Statins control or lower your blood cholesterol. By lowering your blood cholesterol level, you can decrease your chance of having another heart attack or stroke.

You also may be given medicines to relieve pain and anxiety, and treat arrhythmias. Take all medicines regularly, as your doctor prescribes. Don’t change the amount of your medicine or skip a dose unless your doctor tells you to. 

Medical Procedures

Coronary artery bypass grafting also may be used to treat a heart attack. During coronary artery bypass grafting, a surgeon removes a healthy artery or vein from your body. The artery or vein is then connected, or grafted, to bypass the blocked section of the coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This provides a new route for blood to flow to the heart muscle.

Heart-Healthy Lifestyle Changes

Treatment for a heart attack usually includes making heart-healthy lifestyle changes. Your doctor also may recommend:

• Heart-healthy eating
• Aiming for healthy weight
• Managing stress
• Physical activity
• Quitting smoking

Taking these steps can lower your chances of having another heart attack.

Cardiac Rehabilitation

Your doctor may recommend cardiac rehabilitation (cardiac rehab) to help you recover from a heart attack and to help prevent another heart attack. Nearly everyone who has had a heart attack can benefit from rehab. Cardiac rehab is a medically supervised program that may help improve the health and well-being of people who have heart problems.

The cardiac rehab team may include doctors, nurses, exercise specialists, physical and occupational therapists, dietitians or nutritionists, and psychologists or other mental health specialists.

Rehab has two parts:

• Education, counseling, and training. This part of rehab helps you understand your heart condition and find ways to reduce your risk for future heart problems. The rehab team will help you learn how to cope with the stress of adjusting to a new lifestyle and how to deal with your fears about the future.
• Exercise training. This part helps you learn how to exercise safely, strengthen your muscles, and improve your stamina. Your exercise plan will be based on your personal abilities, needs, and interests.

Heart disease is a catch-all phrase for a variety of conditions that affect the heart’s structure and function. Coronary heart disease is a type of heart disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. It is the leading cause of death in the United States.

Coronary heart disease is often caused by the buildup of plaque, a waxy substance, inside the lining of larger coronary arteries. This buildup can partially or totally block blood flow in the large arteries of the heart. Some types of this condition may be caused by disease or injury affecting how the arteries work in the heart. Coronary microvascular disease is another type of coronary heart disease. It occurs when the heart’s tiny blood vessels do not work normally.

Symptoms of coronary heart disease may be different from person to person even if they have the same type of coronary heart disease. However, because many people have no symptoms, they do not know they have coronary heart disease until they have chest pain, a heart attack, or sudden cardiac arrest.

If you have coronary heart disease, your doctor will recommend heart-healthy lifestyle changes, medicines, surgery, or a combination of these approaches to treat your condition and prevent complications.

Causes of Coronary Heart Disease

There are three main types of coronary heart disease: obstructive coronary artery disease, nonobstructive coronary artery disease, and coronary microvascular disease. Coronary artery disease affects the large arteries on the surface of the heart. Many people have both obstructive and nonobstructive forms of this disease. Coronary microvascular disease affects the tiny arteries in the heart muscle.

The cause depends on the type of coronary heart disease. The condition may also have more than one cause, including plaque buildup or problems that affect how the heart’s blood vessels work. 

Plaque buildup

Plaque buildup in the arteries is called atherosclerosis. When this buildup happens in the heart’s arteries over many years, the arteries become narrower and harden, reducing oxygen-rich blood flow to the heart. The result is coronary artery disease.

Obstructive coronary artery disease means the heart’s arteries are more than 50% blocked. The blood flow may eventually be completely blocked in one or more of the three large coronary arteries. In nonobstructive coronary artery disease, the large arteries may be narrowed by plaque, but not as much as they are in obstructive disease.

Small plaques can also develop in the small blood vessels in the heart, causing coronary microvascular disease.

Problems affecting the blood vessels

Problems with how the heart’s blood vessels work can cause coronary heart disease. For example, the blood vessels may not respond to signals that the heart needs more oxygen-rich blood. Normally, the blood vessels widen to allow more blood flow when a person is physically active or under stress. But if you have coronary heart disease, the size of these blood vessels may not change, or the blood vessels may even narrow.

The cause of these problems is not fully clear. But it may involve:

• Damage or injury to the walls of the arteries or tiny blood vessels from chronic inflammation, high blood pressure, or diabetes.
• Molecular changes that are part of the normal aging process. Molecular changes affect the way genes and proteins are controlled inside cells.

In nonobstructive coronary artery disease, damage to the inner walls of the coronary arteries can cause them to spasm (suddenly tighten). This is called vasospasm. The spasm causes the arteries to narrow temporarily and blocks blood flow to the heart.

These problems can also happen in the tiny blood vessels in the heart, causing coronary microvascular disease (sometimes called coronary syndrome X). Coronary microvascular disease can happen with or without obstructive or nonobstructive coronary artery disease.

Risk Factors

There are many risk factors for coronary heart disease. Your risk of coronary heart disease goes up with the number of risk factors you have and how serious they are. Some risk factors—such as high blood pressure and high blood cholesterol—can be changed through heart-healthy lifestyle changes. Other risk factors, such as sex, older age, family history and genetics, and race and ethnicity, cannot be changed.

Age

Genetic or lifestyle factors cause plaque to build up in your arteries as you age. In men, the risk for coronary heart disease starts to increase around age 45. Before menopause, women have a lower risk of coronary heart disease than men. After around age 55, women’s risk goes up. This is likely because women make less estrogen (a female hormone) after menopause. Also, changes in the small blood vessels of the heart as you age raise the risk for coronary microvascular disease.

Environment and occupation

Air pollution in the environment can put you at higher risk of coronary heart disease. The increase in risk may be higher in older adults, women, and people who have diabetes or obesity. Air pollution may cause or worsen other conditions, such as atherosclerosis and high blood pressure, which are known to increase your risk for coronary heart disease.

Your work life can also raise your risk if you:

• Come into contact with toxins, radiation, or other hazards
• Have a lot of stress at work
• Sit for long periods
• Work more than 55 hours a week, or work long, irregular, or night shifts that affect your sleep

Family history and genetics

A family history of early heart disease is a risk factor for coronary heart disease. This is especially true if your father or brother was diagnosed before age 55, or if your mother or sister was diagnosed before age 65. Research shows that some genes are linked with a higher risk for coronary heart disease.

Lifestyle habits

Over time, unhealthy lifestyle habits increase your risk of coronary heart disease because they can lead to plaque buildup in the heart’s blood vessels. Unhealthy lifestyle habits that are risk factors include the following:

• Being physically inactive, which can worsen other heart disease risk factors, such as high blood cholesterol and triglyceride levels, high blood pressure, diabetes and prediabetes, and overweight and obesity.
• Not getting enough good quality sleep, including waking up often throughout the night, which may raise your risk of coronary heart disease. While you sleep, your blood pressure and heart rate fall. Your heart does not work as hard as it does when you are awake. As you begin to wake up, your blood pressure and heart rate increase to the usual levels when you are awake and relaxed. Waking up suddenly can cause a sharp increase in blood pressure and heart rate, which has been linked to angina and heart attacks.
• Smoking tobacco or long-term exposure to secondhand smoke, which can damage the blood vessels.
• Stress, which can trigger the tightening of your arteries, which increases your risk of coronary heart disease, especially coronary microvascular disease. Stress may also indirectly raise your risk of coronary heart disease if it makes you more likely to smoke or overeat foods high in fat and added sugars.
• Unhealthy eating patterns, such as consuming high amounts of saturated fats or trans fats and refined carbohydrates (white bread, pasta, and white rice). This can lead to overweight and obesity, high blood cholesterol, atherosclerosis, and plaque buildup in the heart’s arteries.

Other medical conditions

Other medical conditions that can raise your risk of developing coronary heart disease include:

• Atherosclerosis
• Autoimmune and inflammatory diseases such as Crohns disease, ulcerative colitis, psoriasis, lichen planus, pemphigus, histiocytosis, lupus erythematosus, and rheumatoid arthritis
• Chronic kidney disease
• Congenital coronary artery defects
• Diabetes
• High blood LDL cholesterol (sometimes called “bad cholesterol”)
• High blood pressure
• High blood triglycerides
• HIV/AIDS, especially among older adults. Part of the risk might be due to side effects of HIV treatments.
• Mental health conditions, including anxiety, depression, and posttraumatic stress disorder (PTSD)
• Metabolic syndrome
• Overweight and obesity
• Sleep disorders, such as sleep apnea or sleep deprivation and deficiency

Race or ethnicity

Coronary heart disease is the leading cause of death for people of most racial and ethnic groups in the United States, including African Americans, Hispanics, and whites.

For Asian Americans or Pacific Islanders and American Indians or Alaska Natives, heart disease is second only to cancer. People of South Asian ancestry are at higher risk of developing coronary heart disease and serious complications than other Asian Americans.

Sex

Coronary heart disease affects men and women. Obstructive coronary artery disease is more common in men. However, nonobstructive coronary artery disease is more common in women. Since the nonobstructive type is harder to diagnose, women may not be diagnosed and treated as quickly as men.

If you are a woman having chest discomfort or shortness of breath during physical activity, ask your doctor about tests to check for nonobstructive coronary artery disease or coronary microvascular disease.

Women may have a higher than normal risk for developing coronary heart disease if they have one of the following conditions.

• Endometriosis, which raises the risk for heart disease in younger women
• Gestational diabetes, which can raise the risk for diabetes and metabolic syndrome even after pregnancy and the risk of developing coronary heart disease
• Polycystic ovary syndrome
• Preeclampsia, a condition that can happen during pregnancy and is linked to an increased lifetime risk for coronary heart disease
• Early menopause (before age 40)

Signs, Symptoms, and Complications

Some people have severe symptoms of coronary heart disease. Others have no symptoms at all. If you have “silent” coronary heart disease, you may not have any symptoms until you have a heart attack or other complication.

Signs and symptoms

An acute coronary event, such as a heart attack, may cause the following symptoms:

• Angina, which can feel like pressure, squeezing, burning, or tightness during physical activity. The pain or discomfort usually starts behind the breastbone, but it can also occur in the arms, shoulders, jaw, throat, or back. The pain may feel like indigestion.
• Cold sweats
• Dizziness
• Light-headedness
• Nausea or a feeling of indigestion
• Neck pain
• Shortness of breath, especially with activity
• Sleep disturbances
• Weakness

Women are somewhat less likely than men to experience chest pain. Instead, they are more likely to experience:

• Dizziness
• Fatigue
• Nausea
• Pressure or tightness in the chest
• Stomach pain

Women are also more likely than men to have no symptoms of coronary heart disease.

Chronic (long-term) coronary heart disease can cause symptoms such as the following:

• Angina
• Shortness of breath with physical activity
• Fatigue
• Neck pain

The symptoms may get worse as the buildup of plaque continues to narrow the coronary arteries. Chest pain or discomfort that does not go away or happens more often or while you are resting might be a sign of a heart attack. If you do not know whether your chest pain is angina or a heart attack, call 9-1-1 right away. All chest pain should be checked by a doctor.

Complications

Coronary heart disease can cause serious complications, including the following:

• Acute coronary syndrome, including angina or heart attack
• Arrhythmia
• Heart failure
• Cardiogenic shock
• Sudden cardiac arrest

Complications of coronary heart disease can be life-threatening and may lead to disability.

Treating Coronary Heart Disease

Your treatment plan depends on how severe your disease is, the severity of your symptoms, and any other health conditions you may have. Possible treatments for coronary heart disease include heart-healthy lifestyle changes, medicines, or procedures such as coronary artery bypass grafting or percutaneous coronary intervention.

Your doctor will consider your 10-year risk calculation when deciding how best to treat your coronary heart disease.

Heart-healthy lifestyle changes

Your doctor may recommend that you adopt lifelong heart-healthy lifestyle changes, including:

• Aiming for a healthy weight. Losing just 3% to 5% of your current weight can help you manage some coronary heart disease risk factors, such as high blood cholesterol and diabetes. Greater amounts of weight loss can also improve blood pressure readings.
• Being physically active. Routine physical activity can help manage coronary heart disease risk factors such as high blood cholesterol, high blood pressure, or overweight and obesity. Before starting any exercise program, ask your doctor what level of physical activity is right for you.
• Heart-healthy eating, such as the DASH (Dietary Approaches to Stop Hypertension) eating plan. A heart-healthy eating plan includes fruits, vegetables, and whole grains and limits saturated fats, trans fats, sodium (salt), added sugars, and alcohol.
• Managing stress. Learning how to manage stress, relax, and cope with problems can improve your emotional and physical health.
• Quitting smoking. Visit Smoking and Your Heart and the National Heart, Lung, and Blood Institute’s Your Guide to a Healthy Heart. Although these resources focus on heart health, they include basic information about how to quit smoking. For free help and support to quit smoking, you can call the National Cancer Institute’s Smoking Quitline at 1-877-44U-QUIT (1-877-448-7848). Talk to your doctor if you vape. There is scientific evidence that nicotine and flavorings found in vaping products may damage your heart and lungs.
• Get enough good-quality sleep. The recommended amount for adults is 7 to 9 hours of sleep a day.

Medicines

Your doctor may recommend medicines to manage your risk factors or treat underlying causes of coronary heart disease. Some medicines can reduce or prevent chest pain and manage other medical conditions that may be contributing to your coronary heart disease.

• ACE inhibitors and beta blockers to help lower blood pressure and decrease the heart’s workload.
• Calcium channel blockers to lower blood pressure by allowing blood vessels to relax.
• Medicines to control blood sugar,such as empagliflozin, canagliflozin, and liraglutide, to help lower your risk for complications if you have coronary heart disease and diabetes.
• Metformin to control plaque buildup if you have diabetes.
• Nitrates, such as nitroglycerin, to dilate your coronary arteries and relieve or prevent chest pain from angina.
• Ranolazine to treat coronary microvascular disease and the chest pain it may cause.
• Statins and/or non-statin therapiesto control high blood cholesterol. Your doctor may recommend statin therapy if you have a higher risk for coronary heart disease or stroke or if you have diabetes and are between ages 40 and 75. Non-statin therapiesmay be used to reduce cholesterol when statins do not lower cholesterol enough or cause side effects. Your doctor may prescribe non-statin drugs, such as, ezetimibe, bile acid sequestrants, alirocumab, or evolocumab to lower cholesterol or omega-3 fatty acids, gemfibrozil, or fenofibrate to reduce triglycerides.

Procedures

You may need a procedure or heart surgery to treat more advanced coronary heart disease.

• Percutaneous coronary intervention (PCI) to open coronary arteries that are narrowed or blocked by the buildup of atherosclerotic plaque. A small mesh tube called a stent is usuallyimplanted after PCI to prevent the artery from narrowing again.
• Coronary artery bypass grafting (CABG) to improve blood flow to the heart by using normal arteries from the chest wall and veins from the legs to bypass the blocked arteries. Surgeons typically use CABG to treat people who have severe obstructive coronary artery disease in multiple coronary arteries.
• Transmyocardiallaser revascularization or coronary endarterectomy to treat severe angina associated with coronary heart disease when other treatments are too risky or did not work.
