摘要
目的 :评价经皮冠状动脉腔内成形术 (PTCA)术后的左心功能变化。方法 :用二维彩色多普勒超声心动图对5 8例行 PTCA的冠心病患者 PTCA手术前后的心功能进行检测。结果 :PTCA92例次 (管腔狭窄由 86 %± 14%降至 13%± 2 1%) ,术前心脏 B超提示 ,冠心病患者存在狭窄或梗塞相关的室壁节段运动异常 ,左室收缩、舒张功能明显下降。PTCA手术后 2～ 4周 ,左室收缩功能明显改善 ,EF值比术前明显增高 (P<0 .0 1) ,节段性室壁运动异常率降低 ,左室舒张功能指标较比术前明显改善。结论 :PTCA术后 2～ 4周 ,左室心脏功能明显改善 ,B超可作为评价手术疗效的指标。
AIM:To evaluate left ventricular function after percutaneous transluminal coronary angioplasty (PTCA). METHODS: Changes of left ventricular function in 58 coronary heart disease (CHD) patients were evaluated by Echocardiography before and after (2 to 4 weeks later) PTCA operation. RESULTS: Stenosis diameter before operation were (83±14)% which were decrease to (13±21)% after operation in 92 coronary arteries conducted PTCA. Pre-operation echocardiography detection indicated that there were stenosis or infarction related segmental left ventricular wall motion disorder and systolic or diastolic left ventricular function decreasing in CHD patients, while 2 to 4 weeks after operation, left ventricular systolic and diastolic function were improved, EF value increased significantly (P<0.01) and rate of segmental left ventricular wall motion disorder decreased. CONCLUSION: Left ventricular function were improved significantly 2 to 4 weeks after PTCA and echocardiography could be used as an index for evaluation clinical effectiveness.
