PURPOSE: Beta-blocker is a frequently used medication in cardiovascular diseases. However, long-term benefit of beta-blocker in patients with preserved left ventricular ejection function (LVEF) on major adverse cardiovascular events (MACEs) is uncertain.
METHODS: The Cohort Of patients with high Risk for cardiovascular Events (CORE-Thailand) was a prospective study that enrolled Thai patients with high atherosclerotic risk including multiple atherosclerotic risk factors and established atherosclerotic cardiovascular diseases. Baseline demographic data, co-morbidities and medication were recorded. Patients were followed for 5 years. Patients with LVEF<50% were excluded. Primary outcome was the effect of beta-blocker on the occurrence of MACEs including all-cause death, non-fatal myocardial infarction and non-fatal stroke (3P-MACEs). Propensity score matching was used to control confounding factors.
RESULTS: There was a total of 8513 patients in the pre-matched cohort, 4418 were taking beta-blocker and 4095 were not. After adjustment of confounders, beta-blocker was an independent predictor of 3P-MACEs (adjusted HR 1.29;95% CI 1.12-1.49;p<0.001). After propensity score matching, 4686 patients remained in the post-matched cohort. Propensity score analysis showed consistent results in which patient taking beta-blocker had higher risk of 3P-MACEs (adjusted HR 1.29;95% CI 1.10-1.53;p=0.002). Subgroup analysis in patients with coronary artery disease (CAD) indicated that taking beta-blocker did not increase the incidence of 3P-MACEs (adjusted HR 0.99;95% CI 0.76-1.29) while those without CAD did (adjusted HR 1.51; 95% CI, 1.22-1.86;p-interaction=0.015).
CONCLUSION: In patients with high atherosclerotic cardiovascular risk, taking beta-blockers had a higher risk of 3P-MACEs. Care should be taken when prescribing beta-blockers to patients without a clear indication.
