肺动脉高压和右心室衰竭可致慢性支气管炎(慢支)与肺气肿患者预后不良,因此在不影响动脉氧分压的情况下,需要给予改善肺血流动力学及右心室功能的药物。作者利用无创性方法,对照研究茶碱及舒喘灵对慢支与肺气肿患者左、右心室功能的影响。报告12例慢支与肺气肿忠者,无冠心病、心脏瓣膜病及高血压病的临床征象。5例有右心衰竭史,但研究时无表现。采用多门电路放射性核素(Multiple
Pulmonary hypertension and right ventricular failure can cause poor prognosis in patients with chronic bronchitis (chronic bronchitis) and emphysema, and therefore need to be given drugs that improve pulmonary hemodynamics and right ventricular function without affecting the partial pressure of arterial oxygen. The authors used noninvasive methods to compare the effects of theophylline and salbutamol on left and right ventricular function in patients with chronic bronchitis and emphysema. Report 12 cases of chronic bronchitis and emphysema loyal, no coronary heart disease, valvular heart disease and clinical manifestations of hypertension. Five patients had a history of right heart failure, but no symptoms at the time of the study. Multi - gate radionuclide
