The purpose of the study was to analyze the incidence of recurrent cardiovascular events in obese patients after a myocardial infarction during a 6-month follow-up period, depending on the combination of ticagrelor or clopidogrel with acetylsalicylic acid as a part of dual antiplatelet therapy. Materials and methods. The study involved 75 patients with acute myocardial infarction with ST segment elevation and concomitant obesity. The patients were divided into 2 subgroups: the first included 31 patients who received the combination of acetylsalicylic acid and ticaglelor, and the second – 44 patients treated with the combination of acetylsalicylic acid and clopidogrel in dual antiplatelet therapy. The GRACE scale was used to stratify the risk of hospital and 6-month mortality. Control of the recurrent cardiovascular events presence was carried out after 6 months. Results and discussion. Acute myocardial infarction with ST elevation is still the main cause of mortality and invalidisation of able-bodied population. Regardless of the primary percutaneous coronary intervention or thrombolysis, dual antiplatelet therapy remains the main therapeutic strategy, both in the acute ST-elevation myocardial infarction period and in the remote – for the secondary prevention of possible adverse cardiovascular events, and is a combination of acetylsalicylic acid and a P2Y12 receptor inhibitor. To date, the issue of the choice of a P2Y12 receptor inhibitor in the dual antiplatelet therapy that is used in the treatment of ST-elevation myocardial infarction is an urgent subject of scientific discussion. While observing patients after a myocardial infarction with concomitant obesity over a period of 6 months, it was found that 28 patients had a recurrent myocardial infarction and / or unstable angina, which was 37.56% of all patients. The analysis of the GRACE scale scores in a cohort of patients with recurrent cardiovascular events revealed that all patients were included in high risk group (> 118 points). In the group of patients who received dual antiplatelet therapy with the involvement of acetylsalicylic acid and ticagrelor in 11 people recorded a repeated myocardial infarction and / or unstable angina, which was 14.76%. At the same time, in a group of patients receiving dual antiplatelet therapy in a combination of acetylsalicylic acid with clopidogrel, re-cardiovascular catastrophes were detected in 17 patients, which was 22.8% of all patients with ST-elevation myocardial infarction on the background of concomitant obesity. Conclusion. The patients with obesity after a myocardial infarction who are included in the GRACE high risk group are recommended to be treated with the combination of acetylsalicylic acid and ticagrelor as a result of a notable reduction in the risk of recurrent cardiovascular catastrophes compared with the combination of acetylsalicylic acid and clopidogrel
