Right ventricular diameter predicts all-cause mortality in heart failure with preserved ejection fraction
Left ventricular ejection fraction (EF) is helpful to differentiate heart failure (HF) phenotype in clinical practice. The aim of the study was to identify simple echocardiographic predictors of post-discharge all-cause mortality in hospitalized HF patients. Patients with acute HF (75 ± 9.8 years),...

The aim of the study was to identify simple echocardiographic predictors of post-discharge all-cause mortality in hospitalized HF patients. Patients with acute HF (75 ± 9.8 years), classified in preserved (≥ 50%) and reduced (< 50%) EF (HFpEF and HFrEF, respectively), were enrolled. The mean follow-up period was of 25.4 months. Patients definitively analyzed were 135. At multivariate Cox model, right ventricular diameter (RVd), inferior vena cava diameter (IVCd) and blood urea nitrogen (BUN) resulted to be significantly associated with all-cause mortality in HFpEF (HR 2.4,

These data are indicative that in patients hospitalized with HF, EF is not a suitable predictor of long-term all-cause mortality, whereas, right ventricular volumetric remodeling and IVCd have a prognostic role in HFpEF as well as LAV in HFrEF. Our study suggests that besides EF, other echocardiographic parameters are helpful to optimize the phenotyping and prognostic stratification of HF.</description><identifier>ISSN: 1828-0447</identifier><identifier>EISSN: 1970-9366</identifier><identifier>DOI: 10.1007/s11739-019-02071-x</identifier><identifier>PMID: 30895427</identifier><language>eng</language><publisher>Cham: Springer International Publishing</publisher><subject>Aged ; Aged, 80 and over ; Chronic obstructive pulmonary disease ; Congestive heart failure ; Echocardiography - methods ; Echocardiography - statistics & numerical data ; Ejection fraction ; Female ; Health risk assessment ; Heart failure ; Heart Failure - classification ; Heart Failure - mortality ; Heart Failure - physiopathology ; Heart Ventricles - abnormalities ; Heart Ventricles - pathology ; Humans ; Im - Original ; Internal Medicine ; Italy ; Male ; Medicine ; Medicine & Public Health ; Middle Aged ; Mortality ; Phenotypes ; Phenotyping ; Prognosis ; Risk Factors ; Stroke Volume - physiology ; Urea ; Ventricle ; Weights and Measures - instrumentation ; Weights and Measures - standards</subject><ispartof>Internal and emergency medicine, 2019-10, Vol.14 (7), p.1091-1100</ispartof><rights>Società Italiana di Medicina Interna (SIMI) 2019</rights><rights>Internal and Emergency Medicine is a copyright of Springer, (2019).
