摘要
目的:探讨慢性心力衰竭患者不同左室射血分数(LVEF)对肺功能的影响。方法:对58例慢性心力衰竭患者行心脏彩超及肺功能检查,根据LVEF分组,LVEF>40%为对照组,LVEF≤40%为观察组。肺功能检查指标包括FVC(用力肺活量)、FEV1(第1个1s内的用力肺活量)、FEF50(呼出肺活量50%时的用力呼气流量)3个指标占预计值的百分比,FEV1/FVC的比值。将两组数据进行统计学处理,并进行分析。结果:观察组肺通气功能指标下降明显,FVC由(71.53±6.32)%下降至(52.25±7.28)%,t=10.793;FEV1由(68.70±7.73)%下降至(47.43±5.73)%,t=11.832;FEF50由(77.20±6.49)%下降至(42.00±7.64)%,t=18.955;FEV1/FVC由(75.06±5.52)%下降至(54.14±6.80)%,t=12.907,P均<0.01,两组间比较差异有统计学意义。结论:慢性心力衰竭患者随LVEF降低,肺功能下降明显,主要表现为混合型通气功能障碍。
Objective: To explore chronic heart failure patients with different left ventricular ejection fraction (LVEF) of the influence of the pulmonary function. Methods: 58 cases of chronic heart failure patients with heart colour to exceed check and pulmonary function. According to LVEF group: LVEF〉40% as the control group, LVEF~〈40% as the observa- tion group. Lung function testing index includes FVC (forced vital capacity), both FEV1 (the first 1 s within the forced vital capacity), FEFs0 (breathe out 50% of the vital capacity when expiratory flow) three index was expected to account for the percent- age of value, FEV1/FVC of ratio. Two data statistics processing, and analyzed. Results: The observation group pulmonary ventilation function index down significantly, FVC by (71.53±6.32)% dropped to (52.25±7.28)%, t=10.793; FEV1 by (68.70±7.73)% dropped to (47.43+5.73)%, t=1 1.832; FEF50 by (77.20+6.49)% dropped to (42.00±7.64)%, t=18.955; FEV1/FVC by (75.06±5.52)% dropped to (54.14±6.80)%, t=12.907, P〈0.01, comparative differences between the two groups was statistically significant. Conclusion: Chronic heart failure patients with pulmonary function, reduce LVEF down significantly, main show is mixed type ventilation function obstacle.
