Background: Acute coronary syndromes (ACS) which is consist of ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI) and unstable angina pectoris (USAP) are a group of diseases with acute vascular occlusion. In this article, we aimed to investigate the relationship between ACS types and multivessel disease in patients who underwent coronary angiography. Materials and Methods: A total of 2048 patients with ACS who underwent coronary angiography between July 2019 and September 2022 were included in the study. Demographic characteristics, lipid profile and angiography reports of the patients were examined, as well as epicrisis. Lipid profiles and the number of vessels with critical stenosis- were recorded by forming 3 groups as STEMI, NSTEMI and USAP. Results: 522 (25.4%) STEMI, 1116 (54.5%) NSTEMI and 410 (24.1%) USAP patients were included in the study. The STEMI group was younger than the NSTEMI and USAP group (p<0.001 and p=0.043, respecti-vely), had a higher smoking rate (p=0.043 and p=0.027, respectively), had higher LDL-C values (p=0.040 and p<0.001, respectively). Three or more vessel disease was detected most in the STEMI group com-pared to the NSTEMI and USAP group (p<0.001, for all). There was a weak but positive significant corre-lation between LDL-C and HbA1c values and the number of vessels with coronary occlusion-stenosis (r:0.163, p<0.001; r:0.349, p<0.001, respectively). there was also negative correlation with HDL-C (r:-111, p=0.001). Conclusions: Multiple vessel disease was found to be more common in ACS patients presenting with STEMI. Key Words: Acute coronary syndrome, Multiple vessel disease, Angiography, Revascularization
