In recent years, the study of right ventricular (RV) to pulmonary circulation (PC) coupling in heart failure with preserved ejection fraction (HFpEF) has been a matter of special interest. Tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) ratio has emerged as a reliable noninvasive index of RV to PC coupling. Thus, we hypothesized that TAPSE/PASP would be a predictor of readmission burden in HFpEF. One thousand one hundred and twenty seven consecutive HFpEF patients discharged for acute HF were included. In 367 patients (32.6%), PASP could not be accurately measured by echocardiography, leaving the final sample size to be 760 patients. Negative binomial regression method was used to evaluate the association between TAPSE/PASP ratio and recurrent admissions. Mean age of the cohort was 75.6 ± 9.7 years and 68.3% were women. At a median (interquartile range) follow-up of 2.0 (2.9) years, 352 (46.3%) patients died and 1,214 readmissions were registered in 482 patients (63.4%), being 506 of them HF-related. There was a stepwise increase in the rates of all-cause and HF readmissions by decreasing TAPSE/PASP ratio. After multivariable adjustment, TAPSE/PASP <0.36 was associated with a higher risk of HF-related recurrent admissions (incidence rate ratio [IRR] 1.51, 95% confidence interval [CI], 1.01 to 2.24; p = 0.040), whereas patients in the lowest quintile (TAPSE/PASP <0.28) exhibited the highest risk of both all-cause and HF-related recurrent admissions (IRR 1.40, 95% CI 1.04 to 1.87, p = 0.025; and IRR 1.85, 95% CI 1.22 to 2.80, p = 0.004, respectively). In conclusion, TAPSE/PASP ratio, as a noninvasive index of RV-PC coupling, emerges as a strong predictor of recurrent hospitalizations in HFpEF.
