ABSTRACT

ABSTRACT: There have been few studies of angiotensin receptor blocker (ARB) dose in myocardial infarction (MI) with preserved left ventricular (LV) systolic function. We evaluated the association of ARB dose with clinical outcomes after MI with preserved LV systolic function. We used MI multicenter registry. Six months after discharge, the ARB dose was indexed to the target ARB doses used in randomized clinical trials and grouped as >0%-25% (n = 2333), >25% of the target dose (n = 1204), and no ARB (n = 1263). The primary outcome was the composite of cardiac death or MI. Univariate analysis showed that mortality of those with any ARB dose was lower than those without ARB therapy. After multivariable adjustment, patients receiving >25% of target dose had a similar risk of cardiac death or MI compared with those receiving ≤25% or no ARB [hazard ratio (HR) 1.05, 95% confidence interval (CI) 0.83-1.33; HR 0.94, 95% CI 0.82-1.08, respectively]. Propensity score analysis also demonstrated that patients with >25% dose had no difference in primary endpoint compared with those ≤25% dose or the no ARB group (HR 1.03, 95% CI 0.79-1.33; HR 0.86, 95% CI 0.64-1.14, respectively). The present study demonstrates that patients treated with >25% of target ARB dose do not have better clinical outcomes than those treated with ≤25% of target ARB dose or those with no ARB dose in MI patients with preserved LV systolic function.

ABSTRACT

The relationship between visit-to-visit blood pressure variability (BPV) and cardiovascular outcomes remains unclear. Our study assessed the prognostic implications of visit-to-visit BPV in patients after acute myocardial infarction (AMI). The present study enrolled 7,375 patients who underwent percutaneous coronary intervention for AMI and at least five measurements of blood pressure after hospital discharge. Visit-to-visit BPV was estimated as variability independent of mean. The primary endpoint was all-cause mortality. The secondary endpoints were major cardiovascular events (the composite of cardiovascular death, myocardial infarction, and ischemic stroke) and hospitalization for heart failure. During a median follow-up of 5.8 years, adjusted risks of all-cause mortality, major cardiovascular events, and hospitalization for heart failure continuously increased as systolic BPV and diastolic BPV increased. Patients in the highest quartile of systolic BPV (versus lowest) had increased risk of all-cause mortality (adjusted hazard ratio (aHR) 1.51 [95% confidence interval (CI) 1.23-1.85]), major cardiovascular events (aHR 1.31 [95% CI 1.1-1.55]), and hospitalization for heart failure (aHR 2.15 [95% CI 1.49-3.1]). Patients in the highest quartile of diastolic BPV was also associated with all-cause mortality (aHR 1.39 [95% CI 1.14-1.7]), major cardiovascular events (aHR 1.29 [95% CI 1.08-1.53]), and hospitalization for heart failure (aHR 2.01[95% CI 1.4-2.87]). Both systolic and diastolic BPV improved the predictive ability of the GRACE (Global Registry of Acute Coronary Events) risk score for both all-cause mortality and major cardiovascular events. Higher visit-to-visit BPV was associated with increased risks of mortality and cardiovascular events in patients after AMI.
