Serum sex hormone levels and renin-sodium profile in men with hypertension.
Both a high renin-sodium profile and abnormal levels of sex hormones have been linked to myocardial infarction (MI) in men. The present study was carried out in men with hypertension to determine whether renin-sodium profile and sex hormone levels are related to each other. Renin-sodium profile, estradiol, testosterone, sex-hormone binding globulin (SHBG), and risk factors for MI, ie, cholesterol, insulin, glucose, and blood pressure, were determined in 45 men with hypertension. The mean serum estradiol level of the 13 men with high renin profile (30.1 +/- 6.5 pg/mL) was significantly higher (P = .01) than that of the nine men with low renin profile (22.6 +/- 3.9), while the mean level of the 23 men with normal renin profile was intermediate (26.2 +/- 5.3). The levels of estradiol and plasma renin activity correlated in the 45 patients before (r = 0.48, P = .001) and after (r = 0.46, P = .002) controlling for age. The mean estradiol-to-testosterone ratio was also higher (P = .04) and the mean SHBG level lower (P < .02) in the high renin group, but the mean testosterone level was not significantly different between the high and low renin groups. Although none of the risk factors was significantly different between the high and low renin groups, all of the mean values in the high renin group were in the direction of increased MI risk. These findings suggest that in men with hypertension, renin profile may be related to estradiol level and possibly to risk factors for MI.
