The association between premature coronary artery disease and level of testosterone in young adult males.

Abstract

In this study, 191 patients with premature CAD were compared with 94 normal coronary subjects. Patients in the CAD group were significantly older (41.59 ± 3.79 versus 39.27 ± 4.97 years; P-value < 0.01), and had higher rates of diabetes mellitus (P-value = 0.04) and dyslipidemia (P-value = 0.01). Serum levels of FT and TT were significantly lower in the CAD group than the normal coronary subjects (P-value < 0.01 for both). The rate of subjects with low TT increased by the number of the affected vessels (p-value for trend <0.01) and there was a significant correlation between the Gensini score and FT and TT (r = -0.37, P-value < 0.01 and r = -0.34, P-value < 0.01, respectively). After adjustment for confounders, the association between low TT and CAD remained significant (Odds ratio = 4.30, 95% confidence interval: 1.99-9.32; P-value ≤ 0.001) CONCLUSION: Low levels of testosterone were associated with premature CAD and its severity in young adults.
