Pulmonary hypertension (PH) is an understudied but significant complication of myocardial infarction (MI). Currently, there are no diagnostic algorithms that can predict the development of PH in the setting of myocardial infarction, which requires the development of prediction models based on the results of routine examination, for example, lipid profile. The purpose of the research was to study the parameters of lipid metabolism in men with PH that developed against the background of MI and their impact on the risk of developing PH. The results of examination of men aged 32-60 years with verified MI were studied. According to the level of mean pulmonary artery pressure (MPAP) determined by echocardiography, patients were divided into two groups: the study group (with a MPAP level of more than 20 mm Hg at the end of the third week of MI) and the comparison group (with a normal MPAP level at the end of the third week of MI). The studied indicators were compared based on the Mann-Whitney, Wilcoxon, and Chi-square tests; correlations were performed using the Spearman method. It was found that patients in the study group had lower levels of the atherogenic coefficient (AC) and the total cholesterol/high-density lipoprotein (TC/HDL) index at the end of the third week of MI. Levels of triglycerides (TG) < 1.3 mmol/l and very low density lipoprotein (VLDL) ≥ 1.2 mmol/l, TC/HDL indices < 6.0 and LDL/HDL < 3.2 in the first 48 hours, LDL <2.4 mmol/l, AC value <5.0, TC/HDL indices <6.0 and LDL/HDL <3.2 at the end of the third week of MI influence the risk of developing PH in the subacute period of MI. Correlations have also been established between the level of MPAP and lipid profile parameters. It is advisable to use the obtained results when developing a model for predicting the development of PH against the background of MI.
