Study of Acute Coronary Syndrome in Premenopausal Women in Correlation with Sex Hormones

Higher testosterone and lower Estrogen levels are associated with cardiovascular disease in women. However, studies on endogenous sex hormones and acute coronary syndrome (ACS) in pre-menopausal women are sparse. We studied 50 pre-menopausal women presenting with ACS and age-matched controls who consented to the study with Testosterone, Estradiol, and Sex hormone-binding globulin (SHBG) levels at baseline. They were clinically followed up for 6 months duration. The mean age was 37.42 ± 5.7 years. 48% patients were obese. The mean body mass index was 27.53 ± 5.41 kg/m2. Hypertension followed by Diabetes was the most common risk factor. 14% had family history of coronary artery disease (CAD). 24% had atypical chest pain at presentation. Anterior wall ST elevation myocardial infarction was the most common presentation. Single-vessel disease was seen in 38%; 24% had Non-Obstructive CAD. Ratios of Bioavailable Testosterone: Estradiol, Estradiol: Low-density Lipoprotein (LDL), Estradiol: High-density Lipoprotein, SHBG: LDL, and SHBG: HbA1c were analyzed in cases and controls and were not found to be significantly associated. Endogenous sex hormones were not found to be significantly associated with ACS in premenopausal women.
