What are the echocardiographic and hemodynamic predictors of survival in patients with precapillary pulmonary hypertension?
Specific echocardiographic and hemodynamic parameters, including right ventricular dysfunction and tricuspid regurgitation severity, can effectively stratify mortality risk in patients with precapillary pulmonary hypertension.
Right ventricular dysfunction, moderate-severe tricuspid regurgitation, low cardiac index, and raised right atrial pressure were associated with poor survival for both pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertensive disease patients. The severity of tricuspid regurgitation, myocardial performance index, presence of pericardial effusion, pulmonary vascular resistance, cardiac index, and right atrial pressure may be used to stratify risk of death.
