ACE and coronary artery disorder: In univariate Cox regression analysis, factors significantly associated with the development of composite CV outcome were history of hypertension (HR, 2.399; 95% CI, 1.257–4.579; p = 0.008), use of angiotensin-converting enzyme inhibitor (ACEi) or angiotensin II receptor blocker (ARB) (HR, 1.669; 95% CI, 1.007–2.765; p = 0.047), serum levels of hemoglobin (HR, 0.85; 95% CI, 0.737–0.982; p = 0.027), eGFR (HR, 0.99; 95% CI, 0.98–0.999; p = 0.031), and presence of CAD (HR, 3.45; 95% CI, 1.881–6.325; p ≤ 0.001), and Syntax score (HR, 1.033; 95% CI, 1.015–1.051).
