Abstract:
Objective:We compared the clinical outcomes between β-blocker with angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) in patients with acute myocardial infarction (AMI) without left ventricular systolic dysfunction.Methods:A total of 750 patients who were diagnosed as AMI without left ventricular systolic dysfunction and successfully received percutaneous coronary intervention (PCI) in TEDA International Cardiovascular Hospital from October 2016 to September 2017 were collected retrospectively. We divided the patients into two groups: β-blocker + ACEI group (BB+ ACEI group, n=666) and β-blocker + ARB group (BB+ ARB group, n=84) according to discharge medications. The clinical datas were gathered and the end-point events were followed up. K-M curve was used to describe cumulative survival rate of the two groups. We used Cox regression analysis to compare the clinical outcomes of the two groups. Results:The occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) (8.3% vs 3.4%, HR=2.377, 95% CI: 1.006-5.616, P=0.048), all-cause death (3.6% vs 0.4%, HR=12.951, 95% CI: 1.947-86.159, P=0.008) and non-fatal myocardial infarction (3.6% vs 0.8%, HR=5.231, 95% CI: 1.193-22.934, P=0.028) in the BB+ ARB group was significantly higher than those in the BB+ ACEI group followed up for 13 months. However, there was no difference between the two groups in the incidence of stroke (1.2% vs 1.4%, HR=0.922, 95% CI: 0.117-7.276, P=0.516) and target vessel revascularization (3.6% vs 1.6%, HR=1.607, 95% CI: 0.384-6.729, P=0.516). The cumulative survival rate of BB+ ACEI group was higher than that of BB+ ARB group, with statistically significant difference ( P<0.05). Conclusions:Compared with β-blocker combined with ARB, β-blocker combined with ACEI are more beneficial to reduce the incidence of MACCE, all-cause death and non-fatal myocardial infarction in AMI patients without left ventricular systolic dysfunction after PCI.
