The role of sex @entity230 in @entity453 ( @entity453 ) has been studied for years. In @entity1 after @entity583 has been described. Heart rate variability (HRV) analysis is one of the method of autonomic nervous system evaluation. The aim of the study was to evaluate correlations between sex @entity230 and HRV in 88 @entity1 (aged 36-73, av. 53 yrs), with the history of MI, with angiographically documented @entity453 . In all the @entity1 24-hour Holter monitoring was performed to assess HRV time domain parameters: SDNN, SDNNI, SDANN, rMSSD, pNN50. Levels of @entity251 and @entity53 were measured in two subsequent blood samples, taken with 30 min interval. Free @entity251 index as well as @entity53 / @entity251 ratio were assessed. For statistics r-Spearman test was used. Positive correlations were found between @entity251 and SDNN (r = 0.38, p = 0.03), @entity251 and rMSSD (r = 0.51, p = 0.002) and between @entity251 and pNN50 (r = 0.45, p = 0.007). Since rMSSD and pNN50 are parameters describing parasympathetic activity, our results suggest that in @entity453 @entity1 with the history of @entity583 , @entity251 may influences the function of autonomic nervous system promoting parasympathetic dominance. It can be favorable for the circulatory system function.
