Study of correlation between 2D echocardiographic assessment of right ventricle and outcome of acute heart failure patients
Abstract
Background: Hospital length of stay (LOS) is a key determinant of heart failure hospitalization costs and performance of medical care quality. Right ventricular (RV) dysfunction predicted poor outcome in patients with acute heart failure (AHF). Aim: To study the effect of right ventricular function on length of hospital stay as a predictor in patients with acute heart failure. Methods: A prospective cohort study was conducted in Cardiology Care Units (CCUs) in Zagazig University Hospital and Shark El Madina Hospital from September 2019 to February 2020, we included in this study 99 patients admitted with AHF. Clinical data and baseline RV function assessed by tricuspid annular plane systolic excursion (TAPSE) and S' velocity were collected. Clinical comorbidities including worsening renal function (WRF) were monitored during hospitalization. The primary outcome was hospital LOS. Results: There was statistically significant correlation between WRF, right ventricular systolic dysfunction identified by TAPSE<16 mm and S' <9.5 cm/s and poor outcome in patients with acute heart failure including prolonged LOS. Conclusion: Right ventricular (RV) systolic dysfunction as assessed by TAPSE and S' velocity and diastolic dysfunction were independent predictors of longer LOS in AHF patients. WRF had high prevalence among patients with AHF and associated with poor outcome in AHF patients and prolonged LOS.
