Background: Optimal medical therapy (OMT) and the management of coronary risk factors are necessary for secondary prevention of major adverse cardiac and cerebrovascular events (MACCE) in post-acute coronary syndrome (ACS) patients. However, the effect of post-discharge patient adherence has not been investigated in Japanese patients. Methods and Results: The Prevention of AtherothrombotiC Incidents Following Ischemic Coronary Attack (PACIFIC) registry was a multicenter, prospective observational study of 3,597 patients with ACS. Death or MACCE occurred in 229 patients between hospitalization and up to 1 year after discharge. Among 2,587 patients, the association between OMT adherence and risk factor control at 1 year and MACCE occurring between 1 and 2 years after discharge was assessed. OMT was defined as the use of antiplatelet agents, angiotensin-converting enzyme inhibitors, β-blockers, and statins. Risk factor targets were: low-density lipoprotein-cholesterol <100 mg/dl, HbA1c <7.0%, non-smoking status, blood pressure <130/80 mmHg, and 18.5≤body mass index ≤ 24.9 kg/m2. The incidence of MACCE was 1.8% and associated with female sex (P=0.020), age ≥75 years (P=0.004), HbA1c ≥7.0% (P=0.004), LV ejection fraction <35% (P<0.001), estimated glomerular filtration rate <60 ml/min (P=0.008), and history of cerebral infarction (P=0.003). In multivariate analysis, lower post-discharge HbA1c was strongly associated with a lower risk of MACCE after ACS (P=0.004). Conclusions: Hyperglycemia after discharge is a crucial target for the prevention of MACCE in post-ACS patients.
