The aim: To analyze the metabolic status of patients with coronary artery disease and nonalcoholic fatty liver disease depending on body mass index.
Materials and methods: The cohort of patients included 107 people with coronary artery disease (CAD), nonalcoholic fatty liver disease (NAFLD) and overweight (n=56) or obesity (n=51). In all patients glucose, insulin, HbA1c, HOMA-IR, hsCRP, transaminases, creatinine, urea, uric acid, lipid profile, anthropometric parameters and ultrasound elastography were measured. Results: During the analysis of serum lipid spectrum in patients with obesity: lower levels of HDL and higher TG concentration compared with patients who had overweight. The insulin level was almost twice as high as in patients with overweight and the HOMA-IR index was 3.49 (2.13;5.78), where as in patients with overweight it was 1.85 (1.28;3,01), p<0.01. In patients with coronary artery disease and overweight, the of hsCRP was 1.92 (1.18;2.98) mg/l and was significantly different from the hsCRP level in obese patients, which was 3.15 (2.64;3.66) mg/l, p=0,004. Conclusions: In patients with coronary artery disease, non-alcoholic fatty liver disease and obesity, the metabolic profile was characterized by a more unfavorable lipid spectrum: lower levels of HDL and higher triglicerid concentration. Carbohydrate metabolism in obese patients included disorders such us impared glucose tolerance, hyperinsulinemia and insulin resistance. There was also a correlation between body mass index with insulin and glycated hemoglobin. Higher concentration hsCRP in obese compared with patients with overweight was observed. This confirms the role of obesity in the patogenesis of coronary artery disease, non-alcoholic fatty liver disease and systemic inflammation.
