Beta-blockers after myocardial infarction: Are they useful to all patients? And how long should be the beta-blocker therapy?
AbstractSome observational studies raised questions about the need for Î²-blockers in all patients after a first heart attack. Surprisingly, in some clinical settings, a limited mortality reduction was found in those who received Î²-blockade.Some studies suggest that patients without heart failure may not need post-MI Î²-blockers. The lack of data from randomized controlled clinical trials has led to clinical uncertainty and conflicting recommendations.Â Therefore, there are multiple information to revaluate the value of Î²-blocker therapy after a heart attack in absence of heart failure or left ventricular dysfunction and the time for new trials of an old group of drugs has arrived.
