Abstract

Aim: This study delves into the significance of TAPSE/PASP as a predictive tool, shedding light on its potential to revolutionize the landscape of AHF management.

Methods: We included 152 patients with AHF. Echocardiographic evaluation for left ventricle systolic and diastolic function was performed at the time of admission. RV functions were evaluated by calculating the following (TAPSE, PASP, TAPSE/PASP ratio). Data were analyzed to find the predictors of mortality and/or rehospitalization.

Results: The TAPSE/PASP ratio emerged as a significant independent predictor of clinical outcomes in AHF patients (HR=2.6; 95%CI: 1.04-6.47; p=0.04). Furthermore, it was the sole predictor of rehospitalization for AHF (HR=3.97; 95%CI: 1.38-11.40; p=0.01). It also independently predicted all-cause mortality in AHF, with an HR of 2.73 (95% CI: 1.25-9.12; p=0.03). When evaluating its predictive accuracy, the TAPSE/PASP ratio with a cutoff value <0.35 mm/mmHg demonstrated a sensitivity of 65%, specificity of 70%, and an area under the receiver operating characteristic curve of 0.70 for forecasting adverse outcomes.

Conclusion: The non-invasive TAPSE/PASP ratio is an independent predictor of mortality and /or rehospitalization in patients with acute heart failure.
