“…The cohort clinical study demonstrated that the prevalence of cardiovascular morbidity and mortality increased in patients suffering from prostate cancer (PCa) who have undergone to androgen deprivation therapy (ADT), suggesting that testosterone deficiency was the risk factor of cardiovascular diseases (Gandaglia et al 2015). Moreover, diastolic dysfunction was found in patients with type 2 diabetes with low testosterone level compared with similar patients with normal testosterone levels (Tinetti et al 2015). Furthermore, patients suffering from congestive heart failure (Jankowska et al 2006) and coronary artery disease (Li et al 2012) have been shown to have lower levels of testosterone compared with healthy men, and the severity of these conditions had a strong correlation with the degree of testosterone deficiency (Li et al 2012, Oskui et al 2013.…”

Low testosterone level is associated with increased risks of cardiovascular diseases. As obese-insulin-resistant condition could impair cardiac function and that the incidence of obesity is increased in aging men, a condition of testosterone deprivation could aggravate the cardiac dysfunction in obese-insulin-resistant subjects. However, the mechanism underlying this adverse effect is unclear. This study investigated the effects of obesity on metabolic parameters, heart rate variability (HRV), left ventricular (LV) function, and cardiac mitochondrial function in testosterone-deprived rats. Orchiectomized or sham-operated male Wistar rats (n=36per group) were randomly divided into groups and were given either a normal diet (ND, 19.77% of energy fat) or a high-fat diet (HFD, 57.60% of energy fat) for 12weeks. Metabolic parameters, HRV, LV function, and cardiac mitochondrial function were determined at 4, 8, and 12weeks after starting each feeding program. We found that insulin resistance was observed after 8weeks of the consumption of a HFD in both sham (HFS) and orchiectomized (HFO) rats. Neither the ND sham (NDS) group nor ND orchiectomized (NDO) rats developed insulin resistance. The development of depressed HRV, LV contractile dysfunction, and increased cardiac mitochondrial reactive oxygen species production was observed earlier in orchiectomized (NDO and HFO) rats at week 4, whereas HFS rats exhibited these impairments later at week 8. These findings suggest that testosterone deprivation accelerates the impairment of cardiac autonomic regulation and LV function via increased oxidative stress and impaired cardiac mitochondrial function in obese-orchiectomized male rats.

“…A study in men with acute heart failure reported that low circulating T level was related to worse LV diastolic dysfunction 25 . Similarly, another study in men with asymptomatic type 2 diabetes 26 or with type 2 diabetes without structural heart diseases also found that low T was related to the increased LV filling pressure represented by higher E/e’. On the other hand, some studies have suggested T supplementation after myocardial infarction may worsen the patients’ symptoms 27 – 29 , and Culic et al postulated that T was beneficial only for relatively normal hearts 30 .…”

Serum sex hormones are known to be associated with cardiovascular disease (CVD), but effects in healthy men on cardiac function have not been well quantified. The authors sought to evaluate an association of sex hormones with cardiac structure and function. Study participants were 857 Korean men without significant cardiovascular diseases participating in the Healthy Twin Study. We estimated the associations of total testosterone (TT) and sex hormone-binding globulin (SHBG) with cardiac structure and function measured by echocardiography using a linear mixed regression model with consideration of random and fixed effects of covariates. The ratio of peak early diastolic velocity of mitral inflow over peak early diastolic mitral annular velocity (E/e’) and left atrial volume index (LAVI), functional parameters reflecting left ventricle (LV) filling pressure, were inversely associated with TT even after further cross-adjustment for SHBG level. There was a positive association between LAVI and SHBG, regardless of TT adjustment. These findings suggest that serum testosterone level is positively associated with LV diastolic function independent of SHBG level.
