纳入标准: |
1.年龄18-80周岁(含临界值),性别不限; 2.确诊为急性ST段抬高型心肌梗死,同时满足以下2个条件: (1)缺血性胸痛持续≥30 min; (2)心电图提示2个或2个以上肢体导联ST段抬高≥0.1 mV,和/或在相邻2个或2个以上胸导联ST段抬高≥0.2 mV; 3. 症状发作≤12小时; 4. 冠状动脉造影显示罪犯血管位于冠状动脉主支或其主要分支且符合高血栓负荷标准,即TIMI血栓分级(TTG)≥4级者。 TTG判断标准如下:0级,造影下未见血栓影;1级,可疑血栓,表现为造影下管腔显影模糊、云雾影、病变轮廓不规则或完全闭塞部位突出管腔的平滑新月形影像提示但无法确诊血栓;2级,明确存在血栓,线性尺寸≤1/2血管直径;3级,明确存在血栓,线性尺寸为血管直径的1/2~2倍;4级,明确存在血栓,线性尺寸≥2倍的血管直径;5级,血栓形成导致完全闭塞。 注:对于完全性血栓闭塞患者,在导丝或小球囊通过(或扩张)后进行血栓分级。 5. 患者知情同意、自愿参加本临床研究并签署知情同意书。 |

Inclusion criteria |
1. Age 18-80 years old (including critical value), gender is not limited; 2. Acute ST-segment elevation myocardial infarction was diagnosed, and the following two conditions were met: (1) Ischemic chest pain lasting ≥30 min; (2) ECG indicated ST segment elevation ≥ 0.1mV in 2 or more limb leads, and/or ST segment elevation ≥ 0.2mV in 2 or more adjacent chest leads; 3. Onset of symptoms ≤12 hours; 4. Coronary angiography showed that the offender's blood vessel was located in the main branch or its main branch of the coronary artery and met the criteria of high thrombotic load, that is, TIMI thrombotic classification (TTG) ≥4. The criteria for TTG were as follows: Grade 0, no thrombus shadow was seen under angiography; Grade 1: Suspected thrombus, which was manifested as blurred lumen development, cloud shadow, irregular lesion contour or smooth crescent image of protruding lumen in completely occluded area indicating but unable to confirm thrombus; Grade 2: definite presence of thrombus, linear size ≤1/2 vessel diameter; At grade 3, thrombus is clearly present, and the linear size is 1/2 to 2 times the diameter of the blood vessel; Grade 4: definite presence of thrombus, linear size ≥2 times the vessel diameter; Stage 5, thrombosis leading to complete occlusion. Note: For patients with complete thrombotic occlusion, thrombus grading is performed after the passage (or dilation) of the guidewire or balloon. 5. The patient gave informed consent, voluntarily participated in the clinical study and signed informed consent. |
