Abstract
Background:?It is controversial whether angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) provide significant survival benefits in patients with coronary artery disease (CAD) but without myocardial infarction (MI). This study investigated whether the association of ACEI/ARB therapy with clinical outcome in patients undergoing percutaneous coronary intervention (PCI) was affected by history of MI. Methods and Results:?A total of 11,590 patients undergoing first PCI were divided into 2 groups: those with MI and those without MI. All-cause and cardiovascular mortality were compared between the patients with and without ACEI/ARB at discharge in each group. In patients with MI, significantly lower 3-year all-cause/cardiovascular mortality for patients with ACEI/ARB relative to those without ACEI/ARB was noted in the total patients (all-cause: 6.6% vs. 11.7%, P<0.0001; cardiovascular: 3.8% vs. 6.9%, P<0.0001) and in the 1,007 propensity score-matched pairs (all-cause: 8.2% vs. 11.3%, P=0.018; cardiovascular: 3.7% vs. 5.7%, P=0.014). In patients without MI, however, all-cause (5.2% vs. 5.6%, P=0.56) and cardiovascular (3.2% vs. 3.0%, P=0.23) mortality were similar regardless of whether ACEI/ARB were used or not; and similarly in the 2,061 propensity score-matched pairs (all-cause: 4.1% vs. 5.4%, P=0.33; cardiovascular: 1.4% vs. 2.1%, P=0.30). Conclusions:?Use of ACEI/ARB at hospital discharge was associated with lower all-cause/cardiovascular mortality in revascularized CAD patients with MI, but not in those without MI.
