Coronary Heart Disease
7:00 AM
Coronary heart disease, also known as coronary artery
disease, refers to a narrowing of the coronary arteries, the blood vessels that
supply oxygen and blood to the heart. It is a major cause of illness and death. Coronary heart disease (CHD) normally happens when plaque,
or cholesterol, accumulates on the artery walls. The arteries narrow, reducing
blood flow to the heart.Sometimes a clot can obstruct the flow of blood to the heart
muscle.
CHD commonly causes angina pectoris, or chest pain,
shortness of breath, myocardial infarction, or heart attack, and other
symptoms. CHD is the most common type of heart disease in the United
States, where it accounts for 370,000 deaths every year.
