WebSep 16, 2024 · By Mayo Clinic Staff. Calcium channel blockers are medications used to lower blood pressure. They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.

WebIn coronary artery disease, beta blockers are effective antianginals - improving perfusion decreases angina. In chronic heart failure (which may be due to a number of things), decreasing the rate improves heart function, even though intuitively the beta blockers decrease contractility / ejection fraction. WebIndirect indices of infarct size, namely serum enzyme release and precordial R wave loss are reduced in patients treated early with intravenous beta blockers compared with control patients. However there is no evidence that left ventricular function is preserved by beta blockers. Very large multicentre trials have shown reduction in mortality ...
