Early administration of β-blockers ups survival in ACS

(HealthDay)—For patients with acute coronary syndromes (ACS), early administration of β-blockers is associated with increased short-term survival and improved left ventricular function, according to a study published in the March 1 issue of The American Journal of Cardiology.

Raffaele Bugiardini, M.D., from the University of Bologna in Italy, and colleagues examined whether earlier administration of oral β-blocker therapy correlates with increased short-term survival and improved left ventricular function in with ACS. Data were included for 5,259 eligible patients enrolled in the International Survey of Acute Coronary Syndromes in Transitional Countries registry.

The researchers found that oral β-blockers were administered soon after hospital admission (≤24 hours) in 1,377 patients and later during hospital stay for 3,882 patients. Early β-blocker therapy correlated with reduced in-hospital mortality and reduced incidence of severe (odds ratios, 0.41 and 0.57, respectively). When patients with Killip class III/IV were included as dummy variables, significant mortality benefits with early β-blocker therapy disappeared. Propensity score-matched analyses confirmed these results.

"In patients with ACS, earlier administration of oral β-blocker therapy should be a priority with a greater probability of improving function and in-hospital survival rate," the authors write. "Patients presenting with acute pulmonary edema or cardiogenic shock should be excluded from this early treatment regimen."
