慢性阻塞性支气管炎病人的死亡原因主要是肺心病,而肺心病的发展是由于肺阻力和肺动脉压升高。为研究维拉帕米对肺动脉高压的治疗作用,观察慢性阻塞性支气管炎加重期病人30例,男20例,女10例,年龄21～65岁,平均46岁。病程5～15年,均有中度阻塞型呼吸功能障碍。临床、X线和心电图 Chronic obstructive bronchitis is the main cause of death of patients with cor pulmonale, and pulmonary heart disease is due to lung resistance and pulmonary hypertension. To study the therapeutic effect of verapamil on pulmonary hypertension, 30 patients with chronic obstructive bronchitis were observed. There were 20 males and 10 females, aged from 21 to 65 years, with an average of 46 years. Duration of 5 to 15 years, have moderate obstructive respiratory dysfunction.
