CAD increases the risk for which event due to arterial narrowing?

• A. Myocardial infarction
• B. Stroke
• C. Deep vein thrombosis
• D. Pulmonary edema

Answer: (A)

When coronary arteries are narrowed by atherosclerotic plaques, the heart muscle receives less oxygen, especially during activity. If a plaque ruptures or a clot forms and blocks a coronary artery, blood flow to a region of the heart is cut off, causing myocardial necrosis — a myocardial infarction. This is the event most directly produced by arterial narrowing in CAD. Stroke involves brain vessels, deep vein thrombosis is a venous clot issue, and pulmonary edema is typically a result of heart failure or fluid overload rather than the direct consequence of coronary artery narrowing.
