Background. There are many differences in chest pain symptoms between men and women in terms of location, nature, and additional symptoms. The issue of describing the differences in chest pain in men and women with acute coronary syndrome (ACS), as well as their correlation with changes in the electrocardiogram (ECG) and coronary angiography (CAG) remains relevant.Methods. The study included 588 patients of the cardiology department of the Novokuznetsk City Clinical Hospital No. 1 from 2013 to 2017 with a diagnosis of ACS. Depending on the gender, the subjects were divided into two groups: Group I – 330 men; Group II – 258 women.Results. ACS with ST elevation was more common in men (45.8 %) than in women (33.3 %; p = 0.002). There were no pathological ECG changes in women in 58.1 % of cases, in men – in 45.5 % (p < 0.001). ECG type Q/ST elevation was detected more often in men (45.8 %) than in women (33.3 %; p = 0.002). The absence of coronary artery lesions was observed in 27.9 % of men and 44.2 % of women (p < 0.001). Hemodynamically significant coronary artery stenosis was more common in men (57.6 %) than in women (38.7 %; p < 0.001). In a typical angina clinic, hemodynamically significant coronary artery disease in patients with Q/without ST elevation ACS was detected in 40.2 % of men and in 58.5 % of women (p = 0.002). In the atypical angina clinic, hemodynamically significant lesions of coronary artery were more common in men (40.6 %) than in women (34.1 %; p = 0.02).Conclusion. In women atypical chest pains and intact coronary arteries were detected more often than in men, and hemodynamically significant coronary artery stenosis were found less often than in men. In men, a more pronounced pathology of the coronary arteries in ACS was revealed, in women – great difficulties in diagnosing ACS.
