| Popis: | Aim. To assess association of different dynamics of sex hormones with 10-year survival in men with congestive heart failure (CHF) and implanted cardiac resynchronization therapy (CRT) devices.Methods. Based on tercile of testosterone at the end of the study (TESend), 157 men with CRT (mean age 58.7±9.7 years old; 95 men (60.5%) w/ ischemic CHF) were divided into 3 groups: gr. I (n=52) - TESend13.319.2 nmol/l. Parameters of echocardiography (Echo) were investigated in dynamics, N-terminal fragment of probrain natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), total and free testosterone (TES), estradiol (E2), sex hormone-binding globulin (SHBG), progesterone (PGN), dehydroepiandrosterone sulfate (DHEAS), E2/TES ratio were tested in plasma. Survival in groups was assessed using Kaplan-Meier method.Results. Groups were comparable in age, presence of ischemic CHF, arterial hypertension and surgeries on myocardial revascularization. Higher incidence of atrial fibrillation, obesity, complete left bundle branch block, tendency to higher incidence of diabetes mellitus and higher body mass index was revealed in gr. I compared to gr. III. At baseline, groups didn’t differ in Echo parameters; the highest TES levels were found in gr. III. After CRT, there was less reverse cardiac remodeling, decrease of TES level (pConclusion. Obtained results indicated different dynamics of sex steroids after CRT. Sex hormones variation pattern, interrelated with increase in levels of testosterone, estradiol, dehydroepiandrosterone sulfate and decrease in testosterone to estradiol ratio, was associated with better 10-year survival in men with implantable CRT devices with greater reverse cardiac remodeling and reduction in activity of systemic immune inflammation. |
