Coronary Arteries
Supply blood flow to the heart and ensure adequate oxygenation.
Stint or bypass is used to reduce the oxygen demand by the heart.
Coronary Artery Disease Treatment
Reduce the myocardial oxygen demand by decreasing the heart rate, contractibility, after load or preload.
Antiangial Drugs
Refers to the swelling of tissues that results from excessive accumulation of fluid within the tissue.
Edema
