- W2885896188 abstract "Limited data exist on the prevalence and prognostic importance of right ventricular (RV) dysfunction for heart failure (HF) in the general population.To assess the prevalence of RV dysfunction and its association with HF and mortality in a community-based elderly cohort.Cross-sectional and time-to-event analysis of participants in the Atherosclerosis Risks in the Community (ARIC), a multicenter, population-based cohort study at the fifth study visit from 2011 to 2013, with a median follow-up of 4.1 years. This study included 1004 elderly participants in the ARIC study attending the fifth study visit who underwent both 3-dimensional and 2-dimensional RV echocardiography. Three-dimensional echocardiography data were analyzed between September 15, 2015, and July 24, 2016.Right ventricular ejection fraction (RVEF), RV-pulmonary artery (PA) coupling defined by the RVEF/PA systolic pressure (PASP) ratio, and RV longitudinal strain by 3-dimensional echocardiography.For cross-sectional analysis, the prevalence of RV dysfunction across ACCF/AHA HF stages (0; A, at elevated risk for HF but without structural heart disease or clinical HF; B, structural heart disease but without clinical HF; and C, prevalent HF). For time-to-event analysis, a composite of incident HF hospitalization or all-cause death among participants free of HF at visit 5.Of the 1004 participants, mean (SD) age was 76 (5) years, 385 were men (38%), and 121 were black (12%). Mean (SD) RVEF was 53% (8%). Right ventricular EF, RVEF/PASP, and RV longitudinal strain were each progressively lower across advancing HF stages. Using reference limits from stage 0 participants, RVEF was abnormal in 103 asymptomatic persons with stage A HF (15%) and 27 with stage B HF (24%). Among participants free of HF at baseline, lower RVEF and worse RV-PA coupling (ie, lower RVEF/PASP ratio) both were associated with incident HF or death independent of LVEF and N-terminal pro b-type natriuretic peptide (hazard ratio, 1.20; 95% CI, 1.02-1.42 per 5% decrease in RVEF; P = .03; hazard ratio, 1.65, 95% CI, 1.15-2.37 per 0.5 unit decrease in RVEF/PASP ratio; P = .007).Right ventricular function and RV-PA coupling declined progressively across American College of Cardiology Foundation/American Heart Association HF stages. Among persons free of HF, lower RVEF was associated with incident HF or death independent of LVEF or N-terminal pro b-type natriuretic peptide." @default.
