Finding effective drugs to treat PAH is a problem needed to be resolved. The main purposes of this study therefore were:① To assess the significance of radionuclide ventriculography in the diagnosis of early cor pulmonale and cor pulmonale with right heart failure.② To assess the rule of hemodynamic changes in patients with cor pulmonale especially in those patients who had been in decompensatory phase.③ TO assess the correlation between mean pulmonary artery pressure and right ventricular ejection fraction in order to establish a equation for diagnosing PAH noninvasively.④ To assess the effects of nifedipine , captopril and combining nifedipine with captopril on the treatment of PAH.
