Abstract
Background: Heart failure(HF) related early readmission (<30days) and mortality is higher in elderly patients. Right ventricular (RV) dysfunction is associated with worse prognosis in patients with HF with reduced ejection fraction (HFrEF). We evaluated effect of RV function (as measured by TAPSE - Tricuspid annular plane systolic excursion) and Pulmonary artery systolic pressure (PASP) on early HF readmission and mortality in elderly HF patients. Methods: This is single center observational study of elderly (≥65 years )patients with HFrEF. Patients with principal discharge diagnosis of HFrEF are included (n = 278, age 77 ± 9 years, 38% female, LVEF 29% ± 9%). Demographic and echocardiographic data are collected. TAPSE (as a marker of RV systolic dysfunction) and PASP are measured as per ASE guidelines. Prediction models are performed. Results: Among 278 patients, 62 patients ( 22.3%) had HF related early readmission and 123 patients (44%) died at the end of 5 year. On univariate analysis, older age, Hypertension, Diabetes, higher PASP , RV systolic dysfunction (TAPSE <16mm) and BMI< 25 are predictors of early readmission and mortality (P value <0.05). On multivariate logistic regression analysis, early HF readmission was predicted by TAPSE <16 mm (OR=23.6; p < 0.001; CI 10.23-54.60) and PASP >50 mmHg ( OR = 34; p < 0.001; 95 CI 14.08-82.81); five year all cause mortality was predicted by TAPSE < 16mm (OR = 1.85; p 0.023; 95 CI 1.08-3.16) and PASP >50 mmHg (OR = 2.11; p 0.009; 95 CI 1.19-3.72). Conclusion: TAPSE <16 mm and PASP >50 mmHg are strong predictors of early readmission and five year all cause mortality in elderly HF patients. The assessment of RV function through TAPSE and PASP, helps to risk-stratify elderly patients with HFrEF.
