American Heart Association answered:Coronary artery disease is a condition in which fatty deposits cause thickening of the walls of the arteries that supply blood to the heart muscle. This causes the arteries to narrow, which reduces blood flow. When these arteries become blocked, the heart is deprived of oxygen resulting in heart attack.

SCAI answered:Coronary artery disease, or CAD, is caused by the build-up of fat and cholesterol in the arteries that supply blood to your heart. Arteries are flexible tubes that transport blood throughout your body. The deposits in the arteries are called plaques. As the plaques grow, in a disease process called atherosclerosis, portions of the artery become clogged and narrowed. If an artery is severely obstructed, it reduces blood flow to the heart and can cause chest pain (angina) or even a heart attack.
But what causes plaque to build up in the arteries to begin with? Contributors to heart disease include any of the following:
• aging
• gender (men are at a higher risk younger; women catch up after menopause)
• family history
• smoking
• diet (especially saturated and trans fats, which contain a lot of the “bad,” or
LDL, cholesterol)
• high blood pressure
• diabetes
• physical inactivity
• metabolic syndrome
• stress
• high levels of C-reactive protein (a substance the body produces in reaction to inflammation)Coronary artery disease, or CAD, is caused by the build-up of fat and cholesterol in the arteries that supply blood to your heart.

Coronary artery disease (CAD), also known as coronary heart disease (CHD) or coronary atherosclerosis, involves the progressive narrowing of the arteries that nourish the heart muscle. The narrowing is due to a buildup of fatty plaque (atherosclerosis) along the artery walls. These deposits are composed mostly of cholesterol, other lipids, and fibrous tissue, such as collagen. Coronary disease appears to be a lifelong process in some people, beginning at an early age and progressing slowly until the vessels become so occluded that the heart muscle no longer gets adequate nourishment. The underlying cause is unknown, although it is seen most frequently in people who live in developed industrialized nations.Coronary artery disease (CAD), also known as coronary heart disease (CHD) or coronary atherosclerosis, involves the progressive narrowing of the arteries that nourish the heart muscle.

UCLA Health answered:In the majority of cases, coronary artery disease is the result of a buildup of fatty deposits in the arteries supplying blood to the heart. Less common forms of the disease can occur due to a blood clot, injury, infection, or birth defect. Many factors can increase a person's risk of developing the disease. Smoking, diet, lack of physical activity, high cholesterol, and the presence of other conditions such as diabetes or high blood pressure can increase the risk for coronary artery disease.

Dr. Sameer Sayeed answered:Coronary artery disease can be caused by several different things. Probably the most well known causes are diabetes, which damages the artery walls and causes severe blockages; high blood pressure, which damages the arteries and its walls; smoking, which also damages the artery walls; and high cholesterol, which damages the artery walls and also causes plaques and blockages to form in the arteries. Other risk factors are stress, which can cause coronary artery disease from its effects on blood pressure, and adrenaline surges. Air pollution may have the same effect as smoking. Cocaine and other illicit drugs also damage the vessels. Poor diet, lack of exercise, obesity also all contribute to the development of coronary artery disease.Coronary artery disease can be caused by several different things.

Dr. Charles Neiditz answered:A narrowing or blockage of the coronary arteries is usually caused by atherosclerosis, the buildup of cholesterol and fatty deposits, called plaque, on the inner walls of the arteries. This plaque can reduce blood flow to the heart muscle by clogging the artery or causing abnormal functioning.
Coronary artery disease actually begins before the teen years. That's when blood vessel walls begin to show indications of fatty deposits. As you get older, the fat builds up, causing slight injury to your blood vessel walls. Fat and other substances combine to form the plaque.
Over time, the inside of the arteries develop plaques of different size.
