Hypogonadism tied to higher risk of heart disease in diabetic men: Study
![Hypogonadism tied to higher risk of heart disease in diabetic men: Study Hypogonadism tied to higher risk of heart disease in diabetic men: Study](https://medicaldialogues.in/h-upload/2020/09/14/750x450_134490-coronary-artery-disease.webp)
Kota, Rajasthan: A recent study has pointed out that male patients with type 2 diabetes (T2D) and hypogonadism are at a higher risk of coronary artery disease than males with T2D and eugonadal status. The study findings appear in the Journal of the Association of Physicians of India.
The researchers add that there is definite evidence that low levels of testosterone are tied to increased risk of cardiovascular disease in non-diabetic male patients. Also, testosterone replacement therapy in men with androgen deficiency is associated with a lower risk of cardiovascular outcomes. There was a reduction in sudden cardiac death, revascularization, acute MI, unstable angina, and all-cause mortality in hypogonadal patients who have ever taken testosterone treatment.
Type 2 diabetes is a chronic condition in which insulin hormone is not effectively utilized in the way that it should. Its prevalence has rapidly increased rapidly around the world and is said to affect 463 million people (20-79 years) and the number is estimated to reach approx 700 million by 2045.
T2D is accompanied by several complications including macrovascular (cardiovascular and cerebrovascular), microvascular (neuropathy, nephropathy, and retinopathy), and skin complication. Apart from these, patients with diabetes have several other complications such as those related to hypogonadism, and are often overlooked. Male hypogonadism is a medical condition that results from either an absent or inadequate and impaired secretion of hypothalamic gonadotropin-releasing hormone (GnRH) or of pituitary gonadotropins (follicular stimulating hormone and luteinizing hormone [LH]) or, finally, from a testicular deficiency in sex steroid/sperm production.
Previous studies have shown hypogonadism as a risk factor for coronary artery disease, but no such has been done in patients with type 2 diabetes. In a cross-sectional study, Manoj Saluja, Government Medical College, Kota, Rajasthan, and colleagues looked at the traditional risk factors for coronary artery disease and quantitatively establish hypogonadism as a potential risk factor for coronary artery disease in male patients with T2D.
The study included 100 patients with type 2 diabetes mellitus (50 each with hypogonadism and 50 with eugonadism). The researchers then obtained their biochemical parameters and looked for the prevalence of co-morbid conditions. A correlation of serum testosterone with each quantitative variable using Pearson's Coefficient of correlation and multivariable logistic regression analysis was applied.
Based on the study, the researchers found the following:
- Serum testosterone levels were found to be correlated with age, waist circumference, fasting blood sugar, serum triglycerides and eGFR.
- The prevalence of coronary artery disease was higher in T2DM male patients with hypogonadism as compared eugonadal patients.
- The researchers found a higher odds (1.33 times) for coronary artery disease in male patients with hypogonadism and T2DM as compared to males with T2DM and eugonadism.
"In our study testosterone was found to be a risk factor for coronary artery disease in men with T2DM in our study by calculating the odds ratio (1.33) for CAD in T2DM males with hypogonadism as compared eugonadal males," wrote the authors.
The researchers add that further research is needed for testosterone replacement therapy in males with type 2 diabetes with androgen deficiency in relation to prevention of coronary artery disease.
