Clinical characteristics and in - hospital outcome of acute coronary syndrome in patients with three - vessel and/ or left main coronary artery disease after percutaneous coronary intervention

Background: Many studies in Vietnam have shown that there is an increasing number of patients hospitalized due to acute coronary syndrome (ACS) with multivessel stenosis and/or with left main stenosis. The SYNTAX score based on the results of percutaneous coronary angiography is valuable for risk stratification of patients requiring coronary revascularization, especially for those with multivessel coronary artery disease, then optimizing the clinicians’ decision on percutaneous coronary intervention or bypass surgery for these patients. This study aims to: (1) investigate some clinical characteristics of ACS patients with multivessel and/or left main coronary artery disease (LMCAD); (2) characterize coronary artery lesions according to SYNTAX score by the results of percutaneous coronary angiography; and (3) evaluate intervention outcomes and in - hospital outcomes of these patients treated by percutaneous coronary intervention. Methods: 121 patients with three - vessel and/or LMCAD treated at 115 People’s Hospital in Ho Chi Minh city, from July 2019 to July 2020. Research design: retrospective; collecting clinical characteristics, and coronary intervention results during the in - hospital stay. Results: Mean age 66.03 ± 11.84, male/female ratio 3/1; average total coronary lesions 3.1 ± 1.2 lesions in left anterior descending (LAD) and right coronary artery (RCA), mean SYNTAX score 27.7 ± 6.21; Short - term intervention outcomes: anatomical success 99.2%, procedural success 98.34%, major in - hospital main cardiovascular events including fatal death and other - causes mortality during hospitalization was 2.4%, the cumulative intra - and post - procedure complications was 8.2%.
