Abstract
Background:
Coronary heart disease (CHD) remains a leading cause of morbidity and mortality, particularly in aging populations. Men typically exhibit higher rates of CHD compared to women, with testosterone levels inversely associated with cardiovascular risk. This study investigates the relationship between testosterone levels and angiographically confirmed CHD, disease severity, and myocardial infarction (MI) among CHD cases.
Methods:
A cohort of 1724 male patients undergoing diagnostic or interventional coronary angiography was examined. Demographic, clinical, and biochemical data were collected, including serum total testosterone levels. The severity of CHD was assessed using the Gensini score, and MI cases were diagnosed according to World Health Organization criteria.
Results:
Results revealed significant differences in testosterone levels among CHD subtypes, particularly between MI and unstable angina/stable angina groups (p < 0.001). Testosterone levels were inversely correlated with CHD severity, as evidenced by the Gensini score (Pearson coefficient = -0.062, P = 0.004). Cross-validation random forest analysis demonstrated the significant contribution of testosterone to CHD severity discrimination (p < 0.05).
Conclusions:
There is an association between testosterone and a predisposition to severe CAD indicated by Gensini score and myocardial infarction.
