Term
|
Definition
- Antianginal: Relaxes vascular smooth muscles of both venous and arterial beds, resulting in a net decrease in the myocardial oxygen consumption. It also dilates coronary vessels leading to redistribution of blood flow to ischemic tissue and improved collateral circulation.
- Vasodilation: Dilates peripheral vessels, decreasing venous return to the heart which is useful in treating pulmonary edema and heart failure. Arterial vasodilation decreases afterload, thereby decreasing left ventricular workload and aiding a failing heart.
