SIHD
Also written as: SIHD — Stable Ischemic Heart Disease
Clinical syndrome characterized by predictable chest pain or anginal equivalents due to fixed coronary stenosis. Managed primarily with optimal medical therapy.
Full Definition
Stable Ischemic Heart Disease (SIHD) represents a clinical syndrome of predictable myocardial ischemia due to epicardial coronary artery stenosis, typically manifesting as exertional angina or anginal equivalents. Unlike acute coronary syndromes, SIHD symptoms are stable and predictable with consistent triggers. Current guidelines emphasize optimal medical therapy as first-line treatment, including high-intensity statin therapy, antiplatelet agents, beta-blockers, and ACE inhibitors or ARBs. Revascularization is reserved for patients with refractory symptoms despite optimal medical therapy or specific high-risk anatomic features.
Usage
Usage note: Preferred term over 'stable CAD' in current guidelines; emphasizes ischemia over anatomy.
