有调查显示,急性心肌梗死患者血栓溶解后或冠脉介入术后,超过30％患者出现无血流现象,无血流现象与心脏功能差和预后不良相关。在首次介入治疗时,准确识别易导致无血流现象发生的病变是至关重要的。目前,还没有病变的形态学与无血流现象关系的研究。本研究的目的是,观察介入前血管内超声病变形态学与无血流现象的关系。 方法与结果 本研究共包括连续的100例急性心肌梗死患者,这些患者均在介入前行血管内超声检查;且在症状发作后12h内,成功地
A survey showed that after thrombolysis or coronary intervention in patients with acute myocardial infarction, no blood flow occurred in more than 30% of patients, and no blood flow was associated with poor cardiac function and poor prognosis. During the first intervention, it is crucial to accurately identify the lesions that lead to no blood flow. At present, there is no relationship between the morphological and non-blood flow phenomenon. The purpose of this study was to investigate the relationship between morphological and non-flow-related echocardiographic changes before intervention. Methods and Results A total of 100 consecutive patients with acute myocardial infarction were enrolled in this study. All of these patients underwent intravascular ultrasound before intervention. Within 12 hours after symptom onset,
