不同瓣膜置换术对心功能的影响

Effect of Difference of Cardiac Valve Replacement on Cardiac Function

目的探求老年心脏瓣膜病采用生物瓣膜与机械瓣膜置换术治疗的安全性及应用效果。方法选择2015年10月～2017年9月我院收治的老年心脏瓣膜病患者96例,根据抽签法将其分为两组,各48例。对照组采用机械瓣膜置换术,观察组采用生物瓣膜置换术,比较两组临床疗效、心功能及并发症发生率。结果总有效率:观察组(93.75%)、对照组(75.00%),差异具有统计学意义(P <0.05);并发症总发生率:观察组(8.33%)、对照组(22.92%),差异具有统计学意义(P <0.05);术后3个月:观察组LVEDD、LA、LVEF水平与对照组相比,差异无统计学意义(P>0.05)。结论生物瓣膜置换术疗效更优,并发症发生率少,安全性较高。

Objective: To investigate the effect of difference of cardiac valve replacement on cardiac function. Methods: Totally, 96 old patients with senile heart valvular diseases were admitted and treated in our hospital from October 2015 to September 2017. They were randomly divided into test group and control group with 48 patients in each group. Patients in control group were undergone mechanical valve replacement,while patients in test group were undergone artificial biologic valve replantation. The cardiac function and postoperative complications were compared between the two groups.Results: The total effective rate in test group(93.75%) was significantly higher than that in control group(75.00%). The rate of postoperative complications in test group(8.33%) was significantly lower than that in control group(22.92%)(P < 0.05). However, there was no significant difference between the two groups in LVEDD, LA, and LVEF(P > 0.05).Conclusions: Artificial biologic val ve replantation has better effect than mechanical valve replacement, with less postoperative complications.
