What condition involves a progressive process beginning with damage to the heart’s arteries?

Atherosclerosis is a condition that indeed starts with damage to the heart's arteries and leads to a progressive buildup of plaques made of fat, cholesterol, and other substances in the arteries. This process narrows and hardens the arteries, which can restrict blood flow to the heart and other parts of the body. Over time, atherosclerosis can lead to serious cardiovascular conditions, including angina pectoris, ischemia (reduced blood flow), and myocardial infarction (heart attack). The progression of atherosclerosis is crucial to understanding heart disease, as it sets the stage for these subsequent complications by deteriorating the artery walls and impairing blood circulation. Recognizing this initial stage can aid in preventive measures and early interventions to ensure better heart health.
