The Betami-Danblock Trial: Randomized Discontinuation Of Beta-Blockers After Myocardial Infarction

The Betami-Danblock Trial

The BETAMI-DANBLOCK trial evaluates the safety of discontinuing beta-blockers after myocardial infarction (MI) in patients with preserved or mildly reduced left ventricular ejection fraction (LVEF) (>40%) in the modern percutaneous coronary intervention (PCI) and secondary prevention era.

The trial randomized 5,574 patients within 14 days of MI to either beta-blocker therapy or no beta-blocker, with a median follow-up of 3.5 years.

Results

The primary endpoint, all-cause mortality or major adverse cardiac events (MACE), including recurrent MI, unplanned revascularization, heart failure (HF), ischemic stroke, and malignant ventricular arrhythmia, was significantly reduced with beta-blockers (hazard ratio 0.85, p=0.03).

The primary endpoint is significantly reduced with beta-blockers.

Author's summary: Beta-blockers reduce mortality and MACE after MI.
