UNIT 4 - ANGINA PECTORIS
-
CAUSE
- Insufficient coronary blood flow
- need for oxygen exceeds the supply
- severity of the symptoms of angina is based on the magnitude of the precipitating activity and its effect on activities of daily living
PATHOPHYSIOLOGY
- usually caused by atherosclerotic disease
- associated with a significant obstruction of atleast one major coronary artery
- myocardium extracts a large amount of oxygen from the coronary circulation to meet its continous demands
- when demand increases, flow through the coronary arteries need to be increased
-
