Which of the following is NOT typically considered an indication for Percutaneous Coronary Intervention (PCI)?

Rationale: A. Acute stroke is correct because PCI is a procedure designed to restore blood flow in narrowed or blocked coronary arteries in the heart. An acute stroke involves cerebral arteries, not coronary arteries. Treatment for stroke may include thrombolytics, mechanical thrombectomy, or supportive care, but PCI is not indicated. Performing PCI in a stroke patient would not address the underlying problem and could increase risks of complications, including bleeding. B. Chronic stable angina unresponsive to medical therapy is incorrect because patients with persistent angina despite optimal medical management, such as nitrates, beta-blockers, or calcium channel blockers, may benefit from PCI. PCI improves coronary blood flow, reduces symptoms, and enhances quality of life. C. Multi-vessel coronary artery disease in a patient with heart failure is incorrect because PCI can be indicated in patients with multi-vessel disease, especially if surgical revascularization (CABG) is high-risk or contraindicated. It may help improve myocardial perfusion, reduce ischemia, and potentially improve heart function in selected patients. D. High-risk unstable angina is incorrect because patients with unstable angina and high-risk features, such as ongoing chest pain, ST-segment changes, or elevated troponins, require urgent PCI. PCI can prevent progression to myocardial infarction and improve survival.
