Study notes
Crushing chest pain radiating to the left arm — MI; ECG shows ST elevation; cath lab activated. STEMI (plaque rupture → thrombus → transmural ischemia: prolonged retrosternal pain, ST elevation, troponin rise): primary PCI (balloon + stent) within 90 minutes saves muscle — time is muscle. NSTEMI/unstable angina (partial occlusion — heparin + early angiography). Stable angina (exertional, nitrate-responsive — atherosclerotic narrowing: lifestyle + aspirin, statin, beta-blocker; revascularize if refractory). Post-MI — DAPT (aspirin + clopidogrel), high-dose statin, beta-blocker, ACE inhibitor, cardiac rehab. The arm-radiating crush is the classic — ECG decides in minutes.
