Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialReduction in the need for hospitalization for recurrent ischemic events and bleeding with clopidogrel instead of aspirin. CAPRIE investigators.
Repeat hospitalizations of patients with atherosclerosis represent a considerable burden on the health care system. We sought to determine whether clopidogrel compared with aspirin decreases the need for rehospitalization for ischemia and bleeding. ⋯ Treatment with clopidogrel results in a significant decrease in the need for rehospitalization for ischemic events or bleeding compared with aspirin. This meaningful end point tracks well with other, more traditional measures of outcome and has incremental value beyond such end points.

Randomized Controlled Trial Comparative Study Clinical TrialEsmolol versus diltiazem in the treatment of postoperative atrial fibrillation/atrial flutter after open heart surgery.
Supraventricular tachyarrhythmias are common after open heart surgery. Possible causative factors for these arrhythmias include operative trauma, atrial ischemia, electrolyte imbalances, pericardial irritation, and excess catecholamines. Two agents commonly used to control ventricular rate in atrial fibrillation or atrial flutter (AF/AFL) are beta-blockers and calcium channel blockers. ⋯ Although this is a small study, it suggests that esmolol is more effective in converting patients to normal sinus rhythm than diltiazem during the initial dosing period. No differences in conversion rates were observed between the two groups after 24 hours. Additional studies are needed to confirm whether esmolol is the initial drug of choice in patients with postoperative AF/AFL after coronary bypass surgery.
