Angina

Non-obstructive coronary artery disease (CAD) is more common than often recognized, particularly in women and individuals with risk factors like diabetes or hypertension. Conditions such as INOCA, ANOCA, and MINOCA can cause ischemia and chest pain despite “clean” angiograms, often due to microvascular dysfunction, coronary spasms, or subtle plaque. Diagnosing these conditions requires advanced imaging or invasive studies to assess blood flow and vessel function. Treatment focuses on reducing cardiovascular risk with aspirin, statins, ACE inhibitors, or ARBs, and managing symptoms with beta-blockers or calcium channel blockers. The key takeaway: A normal angiogram doesn’t rule out disease, and these patients need a comprehensive, evidence-based approach to care.
