Tricuspid Annular Plane Systolic Excursion in Acute Decompensated Heart Failure: Relevance for Risk Stratification

Abstract Background Although the prognostic value of right ventricular dysfunction in chronic heart failure (HF) has been studied extensively, it remains insufficiently characterized in the setting of acute decompensated HF (ADHF). We sought to assess whether measurement of tricuspid annular plane systolic excursion (TAPSE) or TAPSE-to–estimated pulmonary arterial systolic pressure (ePASP) ratio allows improvement of risk prediction in ADHF. Methods Four hundred ninety-nine patients with ADHF were studied. Cox regression analyses were used to analyze the association of TAPSE and TAPSE-to-ePASP ratio with 1-year mortality and logistic regression analyses to analyze the association of the 2 variables of interest with adverse in-hospital outcome (AiHO) (in-hospital death plus worsening HF). Results During the 365-day follow-up, 143 patients (28.7%) died. At univariable analysis, both TAPSE ( P  = 0.026) and TAPSE-to-ePASP ratio ( P P  = 0.0270), ischemic heart disease ( P  = 0.020), systolic blood pressure ( P  = 0.006), log N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels ( P P  = 0.001), and hemoglobin levels ( P  = 0.001) at admission were independently associated with 1-year mortality. Adjusting for these covariates, neither TAPSE ( P  = 0.314) nor TAPSE-to-ePASP ratio ( P  = 0.237) remained independently associated with 1-year mortality. Eighty-three patients (16.6%) had an AiHO. At multivariable logistic regression analysis, the TAPSE-to-ePASP ratio was independently associated with an AiHO ( P  = 0.024). The association of TAPSE alone or ePASP alone was not statistically significant. Conclusions Our data strongly suggest that early assessment of TAPSE or TAPSE-to-ePASP ratio does not improve prediction of 1-year mortality over other key risk markers in ADHF. Nonetheless, the TAPSE-to-ePASP ratio did appear to be independently associated with AiHO.
