Direct coronary stenting without predilatation in acute myocardial infarction / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the clinical effectiveness of direct coronary stenting without predilatation in acute myocardial infarction (AMI) Methods Intracoronary stent was directly deployed without ballon predilation in 22 patients within 12 hours from onset Single vessel disease was in 12 patients (54 5%),double vessel disease in 4 patients(18 2%) and triple vessel disease in 6 patients(27 3%) Infarct related arteries (IRA) were left anterior descending artery in 12 patients (54 5%), left circumflex in 5 patients (22 7%), right coronary artery in 5 patients (22 7%) Thrombolysis in myocardial infarction TIMI 1 flow in 5 patients (22 7%), TIMI 2 flow in 13 patients (59 1%) TIMI 3 flow in 4 patients (18 2%) Results Twenty two stents were implanted (1 stent/patient) Post stenting residual stenosis decreased to 3 2?2 9%, stent deployment was successful in 100% of the cases, There were no complications, no death, no Q wave or non Q wave myocardial infarction and no repeated recanalizations during the hospitalization Conclusion Direct coronary stenting without predilatation can be performed in AMI with its high successful rate and low complication
