本文观察低分子肝素与卡托普利治疗肺源性心脏病(肺心病)患者的临床疗效及其对血液粘度与安全性的影响。作者对两组患者分别应用常规疗法和加低分子肝素与卡托普利治疗7d,观察两组临床疗效,血流动力学指标及出血并发症。结果表明,患者在综合治疗的基础上加用低分子肝素与卡托普利可降低肺心病患者的血液粘滞度,明显提高肺心病患者的治疗效果。 This article observed the clinical efficacy of low molecular weight heparin and captopril in patients with pulmonary heart disease (pulmonary heart disease) and its impact on blood viscosity and safety. The two groups of patients were treated with conventional therapy and plus low molecular weight heparin and captopril treatment of 7d, the two groups were observed clinical efficacy, hemodynamic indicators and bleeding complications. The results show that patients combined with low molecular weight heparin and captopril on the basis of comprehensive treatment can reduce the blood viscosity of patients with pulmonary heart disease, significantly improve the treatment of patients with pulmonary heart disease.
