目的 观察急性心肌梗死 (AMI)时行无球囊预扩张直接置入冠状动脉内支架治疗的临床效果。方法 对 2 2例AMI患者在发病 12小时内 ,未经球囊预扩张而直接置入冠状动脉内支架。梗死相关血管 (IRA) (共 2 2支血管 ) ,左前降支 12例 (5 4 5 % ) ,左回旋支 5例 (2 2 7% ) ,右冠状动脉 5例 (2 2 7% )。心肌梗死溶栓试验 (TIMI)血流 1级 5例 (2 2 7% ) ,2级 13例 (5 9 1% ) ,3级 4例 (18 2 % )。结果 2 2例患者共置入 2 2个支架 ,支架置入后TIMI血流 3级 2 1例 (95 5 % ) ,2级 1例 (4 5 % ) ,残余狭窄为 3 2± 2 9% ,支架置入成功率 10 0 %。住院期间无一例死亡、再次心肌梗死及再次靶病变需重复再通治疗。结论 急性心血肌梗死 (AMI)时行无球囊预扩张直接置入冠状动脉内支架治疗 ,成功率高、并发症少 ,TIMI血流 3级达到率高
Objective To observe the clinical effect of direct balloon stenting without coronary balloon stenting in patients with acute myocardial infarction (AMI). Methods Twenty-two patients with AMI were placed in coronary stents directly without balloon dilation within 12 hours. Infarct-related vessels (IRA) (total of 22 vessels), left anterior descending artery in 12 cases (54.5%), left circumflex artery in 5 cases (22.7%) and right coronary artery in 5 cases (22.7%). Thrombolysis in myocardial infarction (TIMI) grade 1 grade 5 cases (22.7%), grade 2 13 cases (591%), grade 3 4 cases (18 2%). Results Twenty-two patients were enrolled in this study. Twenty-one cases (95.5%) of grade 3 TIMI were treated with stent placement, one case (4.5%) with grade 2, and a residual stenosis of 32 ± 29% , Stent placement success rate 10 0%. No one died during hospitalization, repeat myocardial infarction and re-target lesions need to repeat treatment. Conclusions Acute myocardial infarction (AMI) without balloon pre-dilation is directly implanted into coronary stent. The success rate is high, the complication rate is low, the rate of TIMI blood flow grade 3 is high
