经皮冠状动脉腔内成形术前后45例临床及心电图变化分析

【摘要】 目的 观察PTCA手术前后临床和心电图的变化。方法 45例经选择性冠状动脉造影证实的冠心病行PTCA手术的患者 ,对其手术前后心电图的ST段偏移、QTc、T波、心律及临床症状的变化 ,术中并发症的发生及随访结果进行分析。结果 (1)PTCA术后 ,尤其是急性心肌梗塞患者 ,心电图ST段偏移减轻 (P<0.05) ,QTc缩短 (P<0.05) ,T波亦有明显改变。 (2)患者临床症状大多在开通即刻减轻直至消失。 (3)本组仅7例 (15% )发生轻微并发症 ,经常规及时处理后消失。 (4)经临床随访1-24个月 ,仅2例发生再狭窄。 结论PTCA是迅速改善心肌缺血有效的安全的方法 ,其并发症及再狭窄发生率低 ,在有条件的医院可作为首选的治疗措施。而ECG是一种客观、无创伤的评价方法。更多还原

【Abstract】 Objective To observe the clinical and electrocardiogram changes after percutaneous transluminal coronary angioplasty ( PTCA ). Methods Analyses were made on 45 cases who were confirmed suffering from coronary heart disease and confirmed by coronary angiography to analyze their ECG changes. Results (1) The deviation of ST segment was reduced ( P<0.05 ) , QTc was shortened ( P<0.05 ) and T wave was also significantly changed after PTCA procedures, especially in the acute myocardial infarction patients. (2) Clinical symptoms disappeared or relieved immediately after patency in most patients. (3) 7 cases ( 15%) had minor complications and were relieved after regular treatments. (4) Restenosis occurred only in 2 cases during 1- 24 months clinical follow-up. Conclusion PTCA was an effective and safer method for improving the myocardial ischemia with less complications and restenosis while ECG was an objective and noninvasive evaluating method.更多还原
