EFFECTS OF DIFFERENT SEX HORMONES ON CARDIOVASCULAR DISEASE: A META-ANALYSIS AND SYSTEMATIC REVIEW

Abstract

Objective: Sex hormones play different roles in cardiovascular risk of male and female patients. Especially for postmenopausal women, sex hormone disorder is the main reason for their increased risk of cardiovascular disease. This study mainly explores the effects of different sex hormone levels on cardiovascular diseases in men and postmenopausal women. Design and method: This study included 16 studies with 404,474 patients, including 387,361 male patients and 17,113 female patients. Hazard ratio (HR) and 95%CI results of studies on sex hormones and cardiovascular disease risk in the included literature were extracted as research data. The main outcome events are: cardiovascular disease (CVD), heart failure (HF), cardiovascular death, major cardiovascular adverse events (MACE) and all-cause death. This paper mainly researches the effects of sex hormones on cardiovascular risk and the differences of cardiovascular events between men and women. Results: 1. DHT is a protective factor of cardiovascular risk in male patients, HR = 0.83, 95% CI (0.72, 0.96). 2. For postmenopausal women, SHBG and cFT are the risk factors of CVD in postmenopausal women, with HR 95%CI of 1.06(1.01,1.11) and 1.11 (1.04, 1.19) respectively. 3. DHEA and TT is a risk factor for heart failure in postmenopausal women, which can increase the risk by 17% (HR = 1.17, 95% CI (1.09, 1.24)) and HR = 1.07, 95% CI (1.03, 1.12), while the SHBG and DHEA had no significant effect on the occurrence of chronic heart failure. Conclusions: DHT is a protective factor of cardiovascular disease risk in men, and the increase of androgen level is an important risk factor of cardiovascular disease risk in postmenopausal women.
