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58 例行PTCA 的冠心病患者PTCA 手术前后的心功能进行检测。结果 PTCA 92 例次(管腔狭窄由86% ±14% 降至13% ±21% ) , 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. 01) , 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。
Abstract:
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 wallmotion disorder and systolic or diastolic left ventricular function decreasing in CHD patients,while 2 to 4weeks after operation, left ventricular systolic and diastolic function were improved,EF value increased significantly (P < 0. 01) and rate of segmental left ventricular wallmotion disorder decreased. CONCLUSION Lef tventricular function were improved significantly 2 to 4weeks after PTCA and echocardiography could be used as an index for evaluation clinical effectiveness.
