Key result
Right ventricular diastolic function is highlighted as a potential predictor of exercise capacity in patients with pulmonary arterial hypertension.
Why the study?
Detailed evaluations of the right ventricular response to exercise in pulmonary arterial hypertension are limited, and the relative contributions of RV systolic versus diastolic function to exercise capacity remain poorly described.
RV diastolic assessment may aid exercise capacity prediction in PAH; leaves open its role in management or trials.
Extract Right ventricular (RV) dysfunction is a well-recognised contributor to exercise intolerance and poor long-term outcomes in pulmonary arterial hypertension (PAH) [1]; however, detailed evaluations of the RV's response to exercise in PAH are only beginning to be conducted [2]. Furthermore, there are both systolic and diastolic impairments in the pressure-overloaded right ventricle [3], but the relative contributions of RV systolic and diastolic function to exercise capacity in PAH are not well-described.
