title: The effects of different beta-blockers on left-ventricular volume and function after primary coronary stenting in acute myocardial infarction.
abstract: The beneficial effect of beta-blockers is reported in myocardial infarction (MI). This study compared the effects of propranolol and carvedilol on left-ventricular (LV) volume and function after acute MI. Serial echocardiographic studies were performed on acute MI patients who were treated with primary coronary stenting and medical treatment, including propranolol or carvedilol. Determinants of the changes in LV volume and function were identified by regression analyses. At 6 months, there was no significant difference in change in the LV end-diastolic volume between patients receiving 2 beta-blockers. The increase of LV ejection fraction was greater in patients receiving carvedilol. On multivariate analyses, it was found that the kind of beta-blocker had no significant influence on the changes in LV volume or ejection fraction, whereas gender and baseline LV ejection fraction were predictive of change in LV ejection fraction. Compared with propranolol, carvedilol did not have a significant benefit on LV remodeling or function after primary coronary stenting in acute MI.
