Insights
Low testosterone levels are linked to coronary artery disease (CAD) in middle-aged men. Lower testosterone correlates with more severe coronary artery stenosis, indicating a potential protective role for testosterone.
Area of Science:
- Cardiology
- Endocrinology
- Men's Health
Background:
- Endogenous testosterone is recognized for its protective effects against cardiovascular diseases in men.
- Coronary artery disease (CAD) affects middle-aged men, with testosterone levels potentially influencing disease progression.
Purpose of the Study:
- To investigate alterations in testosterone levels among middle-aged men diagnosed with CAD.
- To examine the relationship between serum testosterone concentration and the severity of coronary artery stenosis in these patients.
Main Methods:
- Serum testosterone levels were quantified in 87 middle-aged male patients with CAD (stable angina pectoris, unstable angina pectoris, acute myocardial infarction).
- Coronary angiography was performed, and stenosis severity was assessed using the Gensini coronary score.
- Patients with less than 50% coronary artery stenosis severity were designated as the control group.
Main Results:
- Testosterone levels were significantly lower in patients with stable angina pectoris (488.2 ± 96.8 ng/dl), unstable angina pectoris (411.6 ± 128.6 ng/dl), and acute myocardial infarction (365.3 ± 116.6 ng/dl) compared to controls (562.8 ± 110.2 ng/dl).
- Testosterone levels were lowest in the acute myocardial infarction group, intermediate in the unstable angina pectoris group, and highest in the stable angina pectoris group (all p<0.05).
- A significant negative correlation was observed between the Gensini score and testosterone levels (r=-0.513, p<0.05). Testosterone and BMI were identified as independent predictors for CAD.
Conclusions:
- Middle-aged men with CAD exhibit reduced serum testosterone levels.
- A negative correlation exists between testosterone levels and the severity of coronary artery stenosis in male CAD patients.
Background:
Endogenous testosterone has been shown to provide a protective role in the development of cardiovascular diseases in men. This study investigated the changes of testosterone level and its relationship to the severity of coronary artery stenosis in middle-aged men with coronary artery disease (CAD).
Methods:
Serum testosterone concentration was measured in 87 middle-aged men patients with CAD including stable angina pectoris (SAP), unstable angina pectoris (USAP) and acute myocardial infarction (AMI). All patients underwent coronary angiography and the severity of coronary stenosis was estimated by the Gensini coronary score. The patients with the severity of coronary artery stenosis of less than 50% served as control group.
Results:
The levels of testosterone in SAP group (488.2 ± 96.8ng/dl), USAP group (411.6 ± 128.6ng/dl) and AMI group (365.3 ± 116.6ng/dl) were significantly lower than that in control group (562.8 ± 110.2ng/dl) (all p<0.05). When compared with another group among SAP, USAP and AMI groups, the level of testosterone in the AMI group was the lowest, the USAP group was the median while the SAP group was the highest (all p<0.05). There was a significant correlation between angiographic Gensini score and testosterone level (n=87, r=-0.513, p<0.05). Multiple regression analysis found that testosterone and BMI were independent predictors for CAD (testosterone: odds ratio 0.311, 95% confidence interval 0.174-0.512; BMI: odds ratio 1.905, 95% confidence interval 1.116-2.973).
Conclusion:
The present study showed that middle-aged male patients with CAD present a lower level of serum testosterone and the testosterone level was negatively correlated with the severity of coronary artery stenosis.
