目的早期发现老年肺源性心脏病的肾功能损害,为临床防治提供帮助。方法检测73例老年肺源性心脏病急性加重期患者的血清尿素氮(BUN)、肌酐(Cr)、β2微球蛋白(β2-MG),并与对照组分析对比。结果肺源性心脏病有呼吸衰竭组肾功能明显损害,无呼吸衰竭组虽肾功能尚正常,但比对照组明显升高。结论对老年肺心源性心脏病患者应随时监测肾功能特别是β2-MG,以便及时处理。
Objective Early detection of renal dysfunction in elderly patients with pulmonary heart disease, to provide help for clinical prevention and treatment. Methods Serum urea nitrogen (BUN), creatinine (Cr) and β2 microglobulin (β2-MG) were measured in 73 elderly patients with acute exacerbations of cor pulmonale and compared with those of the control group. Results In patients with pulmonary heart disease, the renal function was significantly impaired in patients with respiratory failure. Although the renal function was normal in no respiratory failure group, it was significantly higher than that in the control group. Conclusion For elderly patients with pulmonary heart disease should be monitored renal function, especially β2-MG, for timely treatment.
