Abstract
- Objective: This study aimed to compare the cardiac function among different sub-types of pulmonary hypertension (PH) and to explore the independent predictors of major adverse cardiovascular events (MACE). Methods: Eighty-seven PH patients diagnosed by right heart catheterization (RHC) were recruited. Patients underwent cardiac magnetic resonance (CMR) and RHC examination within 2 weeks. The CMR images were analyzed to calculate the cardiac functional parameters including right ventricle (RV) and left ventricle (LV) end-diastolic volume index (EDVI), end-systolic volume index (ESVI), stroke volume index (SVI), ejection fraction (EF), tricuspid annular plane systolic excursion (TAPSE), and myocardial mass (MM). The median follow-up time was 46.5 months (interquartile range: 26–65.5 months), and the endpoints were the occurrence of MACE. Results: RVEDVI, LVEDVI, and LVESVI were higher in congenital heart disease–related PH (CHD-PH) than in other sub-types (p < 0.05). RVMM, RVSVI, and RVCI were highest in CHD-PH. There was no significant difference in the prognosis among different sub-types (p > 0.05). Comparing with the non-MACE group, RVEF, TAPSE, and LVSVI significantly decreased in the MACE group, while the RVESVI significantly increased (p < 0.05). TAPSE ≤ 15.65 mm and LVSVI ≤ 30.27 mL/m<superscript>2</superscript> were significant independent predictors of prognosis in PH patients. Conclusion: CHD-PH had a higher RV function reserve but lowest LVEF comparing to other subgroups. TAPSE and LVSVI could contribute to the prediction of MACE in PH patients. Key Points: • CMR imaging is a noninvasive and accurate tool to assess ventricular function. • CHD-PH had higher RV function reserve but lowest LVEF. • TAPSE and LVSVI could contribute to the prediction of MACE in PH patients.
