What describes Coronary heart disease?

What describes Coronary heart disease?

• A. Chronic condition with plaque in coronary arteries leading to thickening and reduced elasticity
• B. Acute infection of heart valves
• C. Acute myocardial infarction only
• D. Pulmonary embolism

Answer: (A)

Coronary heart disease is a long-term process in which plaques build up in the coronary arteries, causing the vessels to thicken, stiffen, and narrow. This reduces blood flow to the heart muscle, especially during activity, and can lead to chest pain and, if a plaque ruptures or blood flow is severely reduced, a heart attack. The other statements describe conditions that are not CHD: an acute infection of heart valves is endocarditis; an acute myocardial infarction is a heart attack event, not the ongoing disease; and a pulmonary embolism is a clot in the lungs.
