Abstract Background Echocardiographic prognostic indicators of precapillary pulmonary hypertension (PH) mortality has been inconclusive. This study aims to examine the prognostic values of right ventricular echocardiographic functional parameters in predicting precapillary PH mortality. Methods Systematic searches were conducted in the ScienceDirect, Medline, and Cochrane databases for longitudinal studies. Assessments included means and hazard ratios (HRs) for Tricuspid Annular Plane Systolic Excursion (TAPSE), Right Ventricular Systolic Pressure (RVSP), Right Ventricular Longitudinal Strain (RVLS), Right Ventricular Fractional Area Change (RVFAC), Right Ventricular Ejection Fraction (RVEF), and Right Ventricular Index of Myocardial Performance (RIMP). Results The meta-analysis included 24 cohort studies comprising 2171 participants. Mean values were as follows: TAPSE 17.62 mm, RVSP 77.50 mmHg, RVLS − 16.78%, RVFAC 29.81%, RVEF 37.56%, and RIMP 0.52. TAPSE (HR: 1.28; 95% CI 1.17–1.40; p < 0.001), RVLS (HR: 1.74; 95% CI 1.34–2.26; p < 0.001), RVFAC (HR: 1.40; 95% CI 1.13–1.75; p < 0.001), RVEF (HR: 1.08; 95% CI 1.02–1.15; p = 0.01), and RIMP (HR: 1.51; 95% CI 1.23–1.86; p < 0.001) emerged as significant prognosticators of precapillary PH mortality, with the exception of RVSP (HR: 1.04; 95% CI 0.99–1.09; p = 0.14). TAPSE summary receiver operating characteristics (sROC) analysis yielded an area under the curve (AUC) of 0.85 [95% CI 0.81–0.88] with a sensitivity of 0.81 [95% CI 0.63–0.91] and a specificity of 0.74 [95% CI 0.54–0.87]. RVLS sROC resulted in an AUC of 0.74 [95% CI 0.70–0.78] with a sensitivity of 0.74 [95% CI 0.57–0.86] and a specificity of 0.69 [95% CI 0.64–0.75]. Conclusions TAPSE, RVLS, RVFAC, RVEF, and RIMP demonstrated promise as valuable prognostic indicators for precapillary PH mortality.
