In recent decades a significant raise in the incidence of myocardial infarction among young women has been recorded. It is presumed that, apart from the classical risk factors, other reasons exist for premature atherosclerosis in young women, related to the homeostasis of gonadal hormones. The aim of the study was to analyze the levels of gonadal hormones (estradiol, progesterone, follicle-stimulating hormone, luteinizing hormone, testosterone and dehydroepiandrosterone) measured in the luteal phase, in 65 normally menstruating women post myocardial infarction (MI) and to investigate a possible relationship between the hormone profile and selected coronary artery disease (CAD) risk factors. The levels of gonadal hormones: estradiol, progesterone, follicle-stimulating hormone, luteinizing hormone, testosterone and dehydroepiandrosterone were measured in the luteal phase. All examined women had normal mean levels of gonadal hormones. In the post MI patients leading a sedentary life style, a significantly lower mean progesterone concentration was observed (16.29 ± 9.11 versus 29.43 ± 21.14 nmol/l, p < 0.05) and significantly higher mean testosterone concentration (2.34 ± 0.98 versus 1.76 ± 1.09 nmol/l, p < 0.05) when compared to patients from the same group, but leading a more active life. In obese post MI women (BMI ≥ 30 kg/m2) a lower mean concentration of progesterone was detected (18.02 ± 8.12 versus 26.16 ± 14.72 nmol/l, p < 0.05), than in slimmer patients from the same group. In post MI women with a positive family history for CAD, a significantly higher mean concentration of testosterone was detected (2.31 ± 1.22 versus 1.67 ± 0.74 nmol/l, p < 0.05) than in patients with no family history. The results suggest a correlation between levels of gonadal hormones and classical CAD risk factors.

Introduction: Pulmonary veins isolation (PVI) is useful method in patients (pts) with mitral valve disease (MVD) and chronic atrial fibrillation (AF) during prosthetic valve implantation. The aim of the study: To evaluate e.ectiveness of PVI in the treatment of AF in pt with MVD during valve implantation. Material and methods: 45 pts (mean age 55 yrs) with AF were operated on for MVD.RF ablation around the pulmonary veins, a lesion between them and to the mitral annulus were performed. There were 44 prostheses implanted, 1 case of mitral valve annuloplasty, associated with tricuspid valve repair (5 pts), aorto-coronary bypass procedure (2 pts), ASD II closure (1 pt). Results: SR was achieved in 2 (44,5%) pts, 21 (46,5%)pts were in AF, 4 (9%) pts needed pacing. No correlation between SR restoration and preoperative echocardiographic parameters, age, gender, NYHA functional class were found. In long-term follow-up 1 pt have reversed AF to SR spontaneously. There were 6 cases of paroxysmal AF,1 pt needed pacemaker implantation. 20 (44,5%) pts are in SR, 20 (44,5%) in AF, 5 (11%) in permanent pacing. Conclusion: PVI with RF use is effective in restoring sinus rhythm in patients with chronic AF secondary to mitral valve disease.
