Clinical analysis of 21 patients undergoing emergency percutaneous coronary intervention for left main artery occlusion
Objective:To analyze the clinical characteristics of patients undergoing emergency percutaneous coronary intervention(PCI)for left main artery occlusion.Methods:From May 2018 to May 2022,the clinical data of 21 patients with acute occlusion of the left main artery confirmed by emergency coronary angiography in our hospital were collected.All patients underwent emergency PCI.According to the survival condition,they were divided into survival group(12 cases)and death group(9 cases).Their clinical characteristics and prognosis were retrospectively analyzed.Results:The case fatality of 21 patients with left main artery occlusion was 42.85%.The levels of creatinine and NT-proBNP in the death group were higher than those in the survival group,and the time from onset to vascular opening was longer than that in the survival group(P<0.05).The stent implantation rate and the proportion of postoperative coronary blood flow returning to TIMI perfusion grade 3 in the survival group was higher than that in the death group(P<0.05).Conclusion:Emergency PCI is an effective method for the treatment of left main artery occlusion at present,but its postoperative case fatality is still high,and there are many factors affecting the prognosis.The optimal treatment of this disease still needs further study.
