Angina Pectoris (AP)
Etiology and Risk Factors
AP + Ischemia | Blood Supply to the Myocardium | Myocardial O2 Demand |
1. Myocardial O2 Demand > Oxygen Supply 2. Cellular Acidosis & Lactate Release 3. ST Depression on ECG → ST Depression in the absence of angina is called = Silent Ischemia !!! Angina = Ischemia | • Coronary Artery, Aortic Stenosis • Coronary Artery Spasm • Hypercoagulation States • Anemia • Increased Heart Rate • |
