Effects of β-blockers and calcium channel blockers in acute myocardial infarction

beta-blockers and calcium channel blockers have been evaluated extensively during the acute phase and following myocardial infarction. beta-blockers, when administered early and intravenously, reduce early mortality, reinfarction and cardiac arrests by about 16%. The reduction in mortality is likely to be due to multiple mechanisms including reductions in cardiac rupture, reinfarction and ventricular fibrillation. Recent data also suggest a …
