Estrogens and myocardial infarction
In recent years, increasing attention of specialists has been attracted by the problems of the relationship between cardiovascular pathology and the state of the endocrine system of the body, in particular the functioning of the gonads. Clinical observations indicate that cardiovascular diseases, including MI, can quite often form on a certain “unfavorable” endocrine basis, and their development is largely determined by gender [5, 68, 72]. hormonal function of the ovaries is significantly lower than in men of the same age, with the onset of menopause, this difference between the sexes disappears [3, 68]. The unequal orientation of the action of estrogen hormones on the cardiovascular system of women and supper, while in the former under conditions of estrogen deficiency their substitution is protective, in men, the use of female sex hormones increases the risk of cardiovascular disease [3, 5, 8, 68]. In vitro and in vivo significant coronary dilator reactions and modulating the effect with respect to the paradoxical coronary spastic effects of atherosclerotically altered blood vessels of the heart was observed with the administration of 17p-estradiol only to postmenopausal women, but not to men [22, 51].
