目的分析急性心肌梗死(acutemyocardialinfarction,AMI)后并发左室附壁血栓临床特点。方法收集我院2002年3月～2008年9月确诊为急性心肌梗死后并发附壁血栓50例患者的临床资料,对其进行回顾性分析。结果广泛前壁心肌梗死、前壁心肌梗死44例(88%)。50例均有节段性室壁运动异常或室壁瘤形成。冠脉造影检查36例(72%),其中33例前降支完全、次全闭塞或中重度狭窄,占91.67%(33/36)。结论前降支血管完全闭塞或次全闭塞、前壁心肌梗死、室壁瘤形成、左室射血分数低是并发左室附壁血栓危险因素。
Objective To analyze the clinical features of paroxysmal left thoracic wall thrombosis after acute myocardial infarction (AMI). Methods The clinical data of 50 patients with mural thrombus diagnosed as acute myocardial infarction from March 2002 to September 2008 in our hospital were collected and analyzed retrospectively. Results A wide range of anterior myocardial infarction, anterior myocardial infarction in 44 cases (88%). All 50 patients had segmental wall motion abnormalities or ventricular wall formation. Coronary angiography 36 cases (72%), of which 33 cases of complete anterior descending artery, total occlusion or moderate to severe stenosis, accounting for 91.67% (33/36). Conclusions A complete occlusion or subtotal occlusion of anterior descending artery, anterior myocardial infarction, aneurysm formation and low left ventricular ejection fraction are risk factors for complicated left ventricular wall thrombosis.
