Resumo
BackgroundThe role of beta-blockers in patients with acute coronary syndromes is mainly derived from studies including patients with ST-segment elevation myocardial infarction. Little is known about the use of beta-blockers and associated long-term clinical outcomes in patients with non-ST-elevation acute coronary syndromes (NSTEACS).MethodsWe analyzed short- and long-term clinical outcomes of 2921 patients with NSTEACS using or not oral beta-blockers in the first 24h of the acute coronary syndromes (ACS) presentation. The association between beta-blocker use and mortality was assessed using a propensity score adjusted analysis (N=1378).ResultsPatients starting oral beta-blockers in the first 24h of hospitalization, compared with patients who did not, had lower rates of in-hospital mortality (OR=0.52, 95% CI 0.33 to 0.74, P=0.002) and higher mean survival times in the long-term follow-up (11.860.4years vs. 9.92 +/- 0.39years, P<0.001).Conclusion The use of beta-blockers in the first 24h of patients presenting with NSTEACS was associated with better in-hospital and long-term mortality outcomes.
