A low testosterone-estradiol ratio in males with atherosclerotic cardiovascular disease was associated with increased risk for systemic inflammation and future cardiovascular events according to a corrected proof published in Cardiovascular Research.
Researchers for the study examined testosterone and estradiol concentrations from blood samples drawn from 611 male patients with severe atherosclerosis undergoing carotid endarterectomy in the Athero-Express Biobank Study.

According to the abstract, a low testosterone-estradiol ratio was linked with unfavorable inflammatory profiles, including higher levels of C-reactive protein (P<0.001) and higher leukocyte counts (P=0.001). There was also a negative association between low testosterone-estradiol ratio levels and neutrophil numbers (P=0.012), plaque calcifications (P=0.044), interleukin-6 (P=0.009), and interleukin-6 receptor (P=0.024) was observed. Multivariate Cox regression analysis suggested that a low testosterone-estradiol ratio was independently linked with a higher risk for major adverse cardiovascular events (P=0.043). These effects were strongest in males with elevated BMI.

In men w/ atherosclerosis, ⬇️ T/E2 ratio associated w/ ⬆️ inflammation, risk of major cardiovascular events, particularily in those with ⬆️ BMIhttps://t.co/vYaIjdEWe3#atherosclerosis #obesity #testosterone #inflammation #cardiovascular

“These effects are strongest in men with elevated BMI and are expected to be affected by aromatase activity in white fat tissues,” the researchers concluded. “Normalization of testosterone-estradiol ratio may be considered as target for the secondary prevention of CVD in men.”
@OSSDtweets council member, @InnovatieHester has a fantastic new paper. Congrats! https://t.co/1lOnLLlQ7l
