Testosterone doubles heart attack risk in some men
Low-T? By now, you’ve likely seen the plethora of ads promoting testosterone therapy for men to boost sex drive – and while it may help in the bedroom, it may also send you to the emergency room, according to a new study confirming the male hormone may double the risk of heart attack in some men.
Previous research studies have demonstrated that men with heart disease doubled their risk of heart attack shortly after they began taking testosterone supplements. This new study confirmed those findings, including that men 65 and older also double their heart attack risk, regardless of whether they have had heart disease or not.
Study leader Sander Greenland, a professor of epidemiology at the UCLA Fielding School of Public Health, says that patients and physicians need to talk about these risks before starting any testosterone treatment.
Like women who underwent synthetic hormone replacement therapy for menopause in years past because it was thought to lower the risk of cancer and other diseases, only for it to end up increasing the risk, physicians previously believed testosterone therapy for men guarded against such diseases, including heart attacks, only to learn later that it has the opposite effect.
In this newest study, published Wednesday in the journal PLoS ONE, the findings confirmed that of numerous other smaller studies conducted earlier, including a study from last November showing that testosterone therapy not only raised the risk of heart attack in men, but it also significantly increased the risk of stroke and death in men who had already suffered from heart disease and low testosterone levels.
Another study released last December revealed that men with increased levels of testosterone were also more likely to have a weak response to an influenza vaccine, or no response whatsoever; thus, meaning they had weakened immune systems.
Meanwhile, low-T commercials are increasingly targeting older men whose testosterone levels are starting to diminish due to age. Yet, older men are the very ones who are most at risk for heart attack when taking the male hormone, as the study confirmed such risk doubled for men over 65 even if they never had heart disease before.
