Introduction:
Distribution of cardiovascular risk factors can change depending on lifestyle changes.

Aim of the research:
To analyze changes in the prevalence of risk factors over a 10-year period.

Material and methods:
The study included 1,993,262 patients with ischemic heart disease, including 1,035,562 with acute coronary syndrome (ACS) and 959,328 with chronic coronary syndrome (CCS).

Results:
In both groups, there was an increase in male patients undergoing procedures and patients with prior percutaneous coronary intervention (PCI), decrease in the prevalence of diabetes, prior stroke, and prior coronary artery bypass grafting (CABG). In the CCS group, there was an increase in prevalence of previous myocardial infarction (MI), kidney disease, and chronic obstructive pulmonary disease (COPD). In the ACS group, there was an increase in active smokers, patients with prior PCI, and those with COPD. Compared to men, women undergoing these procedures had a higher prevalence of hypertension, diabetes, and kidney disease, but were less likely to be active smokers or had prior stroke, MI, PCI, CABG, psoriasis, or COPD. With advancing age, the prevalence of hypertension, diabetes, kidney disease, COPD, and prior stroke, myocardial infarction, PCI, and CABG increased, while the frequency of active smoking, psoriasis, the proportion of male patients, and body weight decreased.

Conclusions:
Over the past decade the prevalence of risk factors changed significantly. Frequency of previous PCI increased and frequency of previous CABG decreased. Among those undergoing PCI, women more frequently suffered from hypertension and diabetes than men. As age increases, diseases and previous procedures that are risk factors for atherosclerosis accumulated.
