本文对70例肺结核患者的左室功能进行观察和探讨。与单纯肺结核患者相比较,合并肺气肿患者的 LVET 缩短,EF、SWI 和 SV 降低,合并肺心病患者上述指标进一步异常,且 PEP/LVET 明显增加。提示肺结核合并肺气肿或肺心病患者存在着不同程度的左室收缩和泵血功能减退。为探讨机制,将患者分别按右室功能和氧合状态分组分析,右室功能减退组 LVET、PEP、PEP/LVET 和 EF 明显异常。低氧血症组 LVET 缩短,PEP/LVET 增加,EF、SV、CI、SWI 和 CWI 减少。提示低氧血症和右室功能减退是肺结核患者左室功能减退的重要机制。
In this paper, 70 cases of pulmonary tuberculosis patients with left ventricular function were observed and discussed. Compared with patients with simple pulmonary tuberculosis, patients with emphysema LVET shortening, EF, SWI and SV decreased in patients with pulmonary heart disease further abnormal above-mentioned indicators, and PEP / LVET significantly increased. Tip tuberculosis with emphysema or pulmonary heart disease in patients with varying degrees of left ventricular systolic and pump dysfunction. To explore the mechanism, patients were divided into groups based on right ventricular function and oxygenation status analysis, LVET, PEP, PEP / LVET and EF were significantly abnormal right ventricular dysfunction group. Hypoxemia group LVET shortened, PEP / LVET increased, EF, SV, CI, SWI and CWI decreased. Tip hypoxemia and right ventricular dysfunction is an important mechanism of pulmonary function in patients with left ventricular dysfunction.
