This process is known as atherosclerosis and the fatty deposits are called atheroma. Atherosclerosis can be caused by lifestyle factors, such as smoking and regularly drinking excessive amounts of alcohol. You're also more at risk of getting atherosclerosis if you have conditions like high cholesterol , high blood pressure hypertension or diabetes.
If a doctor feels you're at risk of coronary heart disease, they may carry out a risk assessment. They'll ask you about your medical and family history and your lifestyle, and they'll take a blood test. Read more about how coronary heart disease is diagnosed. Coronary heart disease cannot be cured but treatment can help manage the symptoms and reduce the chances of problems such as heart attacks. 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. 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.
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.
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.
Plaque can attract platelets and white blood cells to the area of buildup in the large coronary arteries, causing inflammation. Inflammation can also prevent the small arteries of the heart from responding to the physical, electrical, and chemical signals that tell the arteries when the heart needs more oxygen-rich blood. This can lead to coronary microvascular disease. 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. 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 Before menopause, women have a lower risk of coronary heart disease than men. 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. 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.
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 Research shows that some genes are linked with a higher risk for coronary heart disease.
Unhealthy lifestyle habits that are risk factors include the following:. Learn about steps you can take to improve your heart health in our Heart-Healthy Living topic. 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.
People of South Asian ancestry are at higher risk of developing coronary heart disease and serious complications than other Asian Americans. 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. You should start getting screening tests and risk assessments for coronary heart disease around age 20 if you do not have any risk factors for coronary heart disease.
Children may need screening if they have risk factors, such as obesity, low levels of physical activity, or a family history of heart problems. Afterward, your doctor may recommend preventive treatments such as heart-healthy lifestyle changes to help you lower your risk of coronary heart disease.
Screening usually occurs in a doctor's office, but sometimes screenings are done at health fairs, drugstores, or other places. Blood samples might be collected at your doctor's office, a hospital, or a laboratory. Ask your doctor or nurse whether you need to fast not eat or drink anything besides water before the blood tests.
Your doctor may use a risk calculator to estimate your risk of having a heart attack, having a stroke, or dying from a heart or blood vessel disease in the next 10 years or throughout your lifetime. It also factors in whether you smoke or take medicines to manage your high blood pressure or cholesterol. Ask about your risk during your annual check-up. Knowing your risk will help you and your doctor decide on healthy lifestyle changes and possibly medicines to lower your risk.
Risk assessments should be repeated every 4 to 6 years in adults 20 to 79 years of age who do not have heart or blood vessel disease. No single risk calculator is appropriate for all people. Calculators can give you and your doctor a good idea about your risk, but your doctor might have to consider other factors to estimate your risk more accurately. Commonly used risk calculators might not accurately estimate risk in certain situations, such as if you:. In these cases, your doctor may suggest other tests for coronary heart disease even if the ASCVD Risk Estimator says you are not at high risk.
Studies show that heart-healthy living —never smoking, eating healthy, and being physically active—throughout life can prevent coronary heart disease and its complications. Work with your doctor to set up a plan that works for you based on your lifestyle, your home and neighborhood environments, and your culture.
Working with a team of healthcare providers may help with making changes in your diet, being physically active, managing other medical conditions, and helping you quit smoking. Some people have severe symptoms of coronary heart disease.
Others have no symptoms at all. Women are somewhat less likely than men to experience chest pain. Instead, they are more likely to experience:. 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 right away. All chest pain should be checked by a doctor. Your doctor will diagnose coronary heart disease based on your symptoms , your medical and family history, your risk factors , and the results from tests and procedures.
It is important to seek care right away if you have symptoms of coronary heart disease. Your doctor will ask about your eating and physical activity habits, your medical history, your family history, and risk factors for coronary heart disease. Your doctor may ask whether you have any other signs or symptoms. This information can help your doctor determine whether you have complications or other conditions that may cause coronary heart disease.
If you have coronary heart disease risk factors , your doctor may recommend diagnostic tests even if you do not have symptoms. Nonobstructive coronary artery disease and coronary microvascular disease can be missed because patients or doctors may not recognize the warning signs.
Diagnosing these types often requires more invasive tests or specialized tests, such as cardiac PET scans, that are not widely available. 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 year risk calculation when deciding how best to treat your coronary heart disease. Learn more about heart-healthy living. 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. You may need a procedure or heart surgery to treat more advanced coronary heart disease.
If you have been diagnosed with coronary heart disease, it is important that you continue your treatment plan. Get regular follow-up care to control your condition and prevent complications. It is important to get routine medical care and to take all medicines regularly, as your doctor prescribes. Do not change the amount of your medicine or skip a dose unless your doctor tells you to. Talk with your doctor about how often you should schedule office visits and blood tests.
Between visits, call your doctor if you have any new symptoms, if your symptoms worsen, or if you have problems with your blood pressure or blood sugar. Return to Treatment to review possible treatment options for coronary heart disease.
You may be referred for exercise-based cardiac rehabilitation , also called cardiac rehab, to manage symptoms and reduce the chances of future problems such as heart attack. Studies have shown that cardiac rehabilitation lowers the risk of hospitalization and death. It can also improve your quality of life. Your doctor will work with you to manage medical conditions that can raise your risk of heart problems and complications.
Your doctor will likely suggest heart-healthy lifestyle changes, such as eating heart-healthy foods, being physically active, and quitting smoking. Your doctor may refer you to other professionals, such as a registered dietitian or exercise physiologist. Your healthcare team can help you set up a personal plan to meet your health goals.
There are benefits to quitting smoking no matter how long or how much you have smoked. Coronary heart disease risk associated with smoking begins to decrease soon after you quit, and it generally continues to decrease over time. In addition:. Living with heart disease may cause fear, anxiety, depression, and stress. You may worry about having heart problems or making lifestyle changes that are necessary for your health.
Talk with your healthcare team about how you feel. Your doctor may talk to you about:. Coronary heart disease can lead to heart attack or stroke.

Coronary heart disease occurs when the flow of oxygen-rich blood to the heart muscle is blocked or reduced. A stroke is where the blood supply to part of the brain is cut off, which can cause brain damage and possibly death. A transient ischaemic attack also called a TIA or "mini-stroke" is similar, but the blood flow to the brain is only temporarily disrupted.
Read more about stroke and TIAs. Peripheral arterial disease occurs when there's a blockage in the arteries to the limbs, usually the legs. Read more about peripheral arterial disease. Aortic diseases are a group of conditions affecting the aorta. This is the largest blood vessel in the body, which carries blood from the heart to the rest of the body. One of most common aortic diseases is an aortic aneurysm, where the aorta becomes weakened and bulges outwards. This doesn't usually have any symptoms, but there's a chance it could burst and cause life-threatening bleeding.
The exact cause of CVD isn't clear, but there are lots of things that can increase your risk of getting it. These are called "risk factors".
Part of this check involves assessing your individual CVD risk and advising you how to reduce it if necessary. High blood pressure hypertension is one of the most important risk factors for CVD. If your blood pressure is too high, it can damage your blood vessels.
