Abstract Objective To evaluate the therapeutic effect and safty of aspiration thrombectomy catheter and stent implantation for patients with acute myocardial infarction complicated by cardiogenic shock. Methods The coronary thrombus aspiration group which consisted of 39 patients with acute myocardial infarction(AMI) complicated by cardiogenic shock(CS) of 39 infarction related coronary artery (IRA) in 46 target lesion underwent emergency aspiration thrombectomy catheter and stent implantation. Results The control group consisting of 32 cases of postoperative coronary blood flow by thrombolysis in myocardial infarction(TIMI) included grade Ⅲ in 30 cases (93.8%), grade Ⅱ (TIMI) in 1 case (3.1%) and grade Ⅰ in 1 case (3.1%). The success rates of IRA and interventional treatment of target lesion were 93.8% and 84.4%, respectively(successful treatment to restore blood flow TIMI Ⅲ). During 12 months of follow-up,in the 29 patients from the control group,there were digestive tract hemorrhage in 2 cases (6.3%), heart failure in 4 cases (12.5%), death in 1 case (3.1%), acute myocardial infarction again in 3 cases (9.4%).In the 39 cases from the coronary thrombus aspiration group, the success rates of aspiration thrombectomy, IRA and interventional treatment of target lesion were 92.1%,92.3%(P=0.81)and 84.6%,respectively(P=0.16). Conclusions The application of emergency coronary aspiration thrombectomy catheter and stent implantation in patients with acute myocardial infarction and cardiac shock is safe and effective.
