Abstract
Diastolic dysfunction (DD) and left ventricular remodeling (LVR) characterize patients at risk for heart failure (HF). To assess the prognostic impact of different diastolic function algorithms and a complex LVR classification (CRC) in asymptomatic subjects with preserved ejection fraction (EF) at risk for HF. We analyzed 1923 asymptomatic patients (male 43%; age 57, 33-76 years) with at least one cardiovascular risk factor and preserved (> 50%) EF. We used three algorithms for LV diastolic function assessment (Paulus et al. in Eur Heart J 28(20):2539-2550, 2007; Nagueh et al. in J Am Soc Echocardiogr 22(2):107-133, 2009, Eur Heart J Cardiovasc Imaging 17(12):1321-1360, 2016), and two algorithms for LVR (classic and CRC). We considered a composite end-point: cardiac death and hospitalization for HF. The highest presence of DD was diagnosed by Nagueh 2009 (211, 11%), while the prevalence according to Nagueh 2016 (63 patients, 3.2%) turned out to be the lowest (p < 0.001 vs the other algorithms). According to CRC, 780 (48.6%) patients had normal or physiologic hypertrophy, 298 (15.5%) concentric remodeling, 85 (4.4%) eccentric remodeling, 294 (15.3%) concentric hypertrophy, 39 (2%) mixed hypertrophy, 80 (4.1%) dilated hypertrophy...Continue Reading
