尘肺并发肺心病是由于作业工人长期吸入粉尘后,致肺部弥漫性纤维化,肺血管病变,引起肺动脉高压。久之右室肥大,最后发展为右心衰。据资料统计,尘肺并发肺心病约占尘肺并发症的20～30％,其死亡率均占30～50％。笔者采用低分子右旋糖酐、复方丹参治疗煤工尘肺并发肺心衰6例,经临床观察取得较满意疗效,现报告如下:
Pneumoconiosis pneumoconiosis is due to long-term inhalation of dust workers, caused by diffuse pulmonary fibrosis, pulmonary vascular disease, causing pulmonary hypertension. Long time right ventricular hypertrophy, the final development of right heart failure. According to statistics, pneumoconiosis pneumoconiosis pneumoconiosis accounts for about 20 to 30% of pneumoconiosis complications, the mortality rate of 30 to 50%. The author uses low molecular weight dextran, compound Danshen treatment of coal workers pneumoconiosis complicated by pulmonary heart failure in 6 cases, obtained by clinical observation more satisfactory efficacy, are as follows:
