The assessment of the adiponectin/leptin ratio in patients with MI reported its significant decrease in all patients at the time of admission [mean values of 0.5 (0.48;0.52) to 0.38 (0.378;0.391) in Groups 1 and 2, respectively], compared with the ratio in the control group [mean values of 1.44 (1.43;1.448)]. This evidence concerns the gene LEP and myocardial infarction.
