01
Overview
NSTEMI is an acute myocardial infarction characterized by clinical evidence of myocardial ischemia with troponin elevation but without persistent diagnostic ST-segment elevation.
02
Clinical Features
Symptoms can resemble STEMI and may include chest pressure, dyspnea, diaphoresis, nausea, or atypical discomfort.
03
Investigation
Serial ECGs and high-sensitivity cardiac troponin measurements are central to diagnosis.
Risk stratification determines the urgency of invasive assessment.
04
Management
Management includes antithrombotic therapy, anti-ischemic treatment, secondary prevention, and coronary angiography according to the patient's risk profile and clinical stability.
05
Clinical Pearls
OSMOND PEARL
NSTEMI often requires serial ECGs + serial troponins + risk stratification rather than relying on a single test.
