6分钟步行试验结合心脏彩超血清钙镁测定对慢性肺源性心脏病的严重程度及预后的评判

The 6 Minute Walk Test Combined With Echocardiography and Serum Calcium and Magnesium Determination of the Severity and Prognosis of Chronic Pulmonary Heart Disease Evaluation

目的探讨6分钟步行试验(6MWT)结合心脏彩超血清钙镁测定对慢性肺源性心脏病的严重程度及预后评判价值。方法 160例慢性肺源性心脏病患者采用多普勒超声诊断仪检测,入院时进行6MWT及血清钙镁测定。结果血钙和血镁随着6MWT(3 m、12 m、21 m、30 m)增加,轻度比例逐渐升高,中度和重度比例均逐渐降低。预后不良及复发患者随着6MWT(3 m、12 m、21 m、30 m)增加逐渐的降低。结论 6分钟步行试验结合心脏彩超血清钙镁测定可以有效判断慢性肺源性心脏病严重程度和预后。

Objective To explore the judgmental value of 6 minute walk test（6MWT） combined with echocardiography and serum calcium and magnesium examination on the severity and prognosis of chronic pulmonary heart disease. Methods 160 cases of pulmonary heart disease patients underwent Doppler ultrasound test, 6MWT and serum calcium and magnesium were measured on admission. Results The serum calcium and magnesium increased with the increase of 6MWT（3 m, 12 m, 21 m, 30 m）, the proportion of mild degree gradually increased, the proportion of moderate and severe gradually decreased. Patients of poor prognosis and relapse gradually decreased with the increase of 6MWT（3 m, 12 m, 21 m, 30 m）. Conclusion 6MWT combined with echocardiography and serum calcium and magnesium examination can effectively determine the severity and prognosis of chronic pulmonary heart disease.
