Differences in right ventricular dysfunction in patients with idiopathic pulmonary hypertension versus secondary pulmonary hypertension.

Introduction: Right ventricular (RV) function in the setting of pulmonary hypertension based on different etiologies has not been well studied. In this study, we evaluated the RV function in patients with idiopathic pulmonary hypertension (IPH) versus secon-dary pulmonary hypertension (SPH) due to congestive heart failure.

Material And Method: Forty-five patients with pulmonary hypertension and New York Heart Association (NYHA) functional class II or III were enrolled.
