Myocardial Infarction

Myocardial infarction is myocardial necrosis due to prolonged ischemia from coronary occlusion (atherothrombosis), presenting with chest pain, ECG changes, and biomarker rise. It is classified as STEMI/NSTEMI. Treatment: urgent reperfusion (primary PCI preferred, fibrinolysis if not available); antiplatelets/anticoagulation; statin/beta-blocker/ACEi; manage complications; secondary prevention and cardiac rehab to reduce recurrence.

Common Symptoms

Chest pain/pressure; diaphoresis; dyspnea; ECG/troponin changes; by STEMI/NSTEMI

Causes and Pathogenesis

Coronary atherothrombosis causes prolonged ischemia and myocardial necrosis.

Treatment

Urgent reperfusion; DAPT/statin/BB/ACEi; manage complications; secondary prevention/rehab

Preventive Measures

Risk-factor control; antiplatelet/statin; cardiac rehab.

Department to Visit

It is recommended to visit the Cardiology/Emergency department; an appointment can be booked on this platform before the visit.
