OBJECTIVE: To study the prognostic role of right ventricular systolic pressure (RVSP) in patients with heart failure (HF). BACKGROUND: Although RVSP is a readily available echocardiographic parameter, it is often underused. Its prognostic role in patients with heart failure is not well established compared with pulmonary artery pressure measured by right heart catheterization. METHODS: This single-center retrospective cohort study included patients with acute heart failure hospitalization admitted to the hospital from January 2005 to December 2018. The primary predictor was right ventricular systolic pressure (RVSP) obtained from bedside transthoracic echocardiography at admission. We divided RVSP into two groups, RVSP <40 mm Hg (reference group) and RVSP ≥40 mm Hg. Primary outcome was all-cause mortality. Secondary outcomes were all-cause readmission and cardiac readmission. We conducted propensity-score matching and applied cox-proportional hazard model to compute hazard ratio (HR) with 95% confidence interval (CI). RESULTS: Out of 972 HF patients, 534 patients had RVSP <40 mm Hg and 438 patients had RVSP ≥40 mm Hg. Patients with RVSP ≥40 mm Hg compared with RVSP <40 mm Hg were associated with higher rates of death [HR: 1.60, 95% CI: 1.22-2.09, P-value = 0.001], all-cause readmissions [HR: 1.37, 95% CI: 1.09-1.73, P-value = 0.008] and cardiac readmissions [HR: 1.41, 95% CI: 1.07-1.85, P-value = 0.014]. CONCLUSION: Higher RVSP (≥40 mm Hg) in HF patients was associated with higher rates of death, all-cause readmissions, and cardiac readmissions. RVSP can be considered as a prognostic marker for mortality and readmission.
