[Leptinemia in persons with acute myocardial infarct].
The purpose of the study was to verify whether the currently reported relationship between leptinemia and adipose tissue mass can be applied to cases of acute coronary attack. An increased number of cytokines has been reported in severe acute myocardial infarctions so that correlation between cytokines and leptin was investigated. Correlation between standard coronary markers and leptinemia was also studied. We examined 48 probands, patients of the Coronary Unit, Hospital, Sternberk, who were hospitalized for acute myocardial infarction (AMI--16 probands) or for unstable angina pectoris (UAP--22 probands). The persons with AMI had leptinemia and a higher concentration of interleukine-6 (Il-6) and of cardial troponine-I (cTn-I) than individuals without coronary accident (UAP). Early after the acute coronary lesion, leptinemia in persons with AMI displayed a statistically significant positive correlation with concentration of interleukine-6 and subsequently of markers of coronary lesion severity (cTnI). No correlation between leptinemia and body weight was found in those probands. This study proved that leptinemia in the AMI individuals is influenced directly by concentration of cytokines which leads to leptin superproduction by fat cells and leptin resistance.
