Abstract

Abstract : Supplemental Digital Content is available in the text Abstract : Abstract: Because it remains uncertain whether β-blockers (BBs) and/or renin–angiotensin system inhibitors benefit a broad population of acute myocardial infarction (AMI) patients, we sought to evaluate the effectiveness of these drugs in improving survival for post-AMI patients who underwent a percutaneous coronary intervention (PCI). From the nationwide data of the South Korea National Health Insurance, 33, 390 patients with a diagnosis of AMI who underwent a PCI between 2009 and 2013 and survived at least 30 days were included in this study. We evaluated the risk of all-cause death for patients treated with both BB and angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor antagonist (ARB) (n = 16, 280), only BB (n = 3683), and only ACEI/ARB (n = 9849), with the drug-untreated patients (n = 3578) as the reference. Over a median follow-up of 2.4 years, although treated patients displayed a trend toward improved survival, there were no significant differences in the adjusted risk of all-cause death when patients were treated with both drugs (hazard ratio [HR] 0.86, 95% confidence interval [CI] 0.70–1.06, P = 0.154), BB (HR 0.88, 95% CI 0.68–1.14, P = 0.325), or ACEI/ARB (HR 0.84, 95% CI 0.68–1.04, P = 0.111). No additional benefit was found for the combination therapy compared with either isolated BB (HR 0.98, 95% CI 0.80–1.21, P = 0.856) or ACEI/ARB (HR 1.03, 95% CI 0.89–1.19, P = 0.727) therapy. Treatment with BB and/or ACEI/ARB has limited effect on survival in unselected nonfatal AMI patients who undergo PCI.
