Background An echocardiographic right/left ventricular end-diastolic diameter ratio (RV/LV ratio) 〉0.9 is an independent predictor of poor prognosis in patients with acute pulmonary embolism. Right ventricular dilation is a common characteristic of both acute pulmonary embolism and idiopathic pulmonary arterial hypertension (IPAH). However, the prognostic value of the RV/LV ratio in patients with IPAH is unknown. Methods Ninety-five consecutive patients with newly diagnosed IPAH were included, 17 were re-evaluated by echocardiography after 3-12 months of targeted therapy, Follow-up data were obtained by telephone interviews and review of the patients' records. 展开更多
