Testosterone therapy may improve heart health for older men
Scientists have discovered that men whose lower levels of testosterone were given testosterone substitute therapy also possessed a reduced chance of cardiac arrest, stroke and all sorts of-cause mortality.
Testosterone is not usually prescribed with the aim of improving heart health, yet restoring testosterone to normal levels could benefit cardiovascular health.
The research, printed within the European Heart Journal, utilizes data acquired in the Veterans Matters database in excess of 83,000 patients.
“It’s the first study to show that significant benefit is noted only when the dose is sufficient to normalize the entire testosterone levels,” the authors write. “Patients who unsuccessful to offer the therapeutic range after testosterone substitute therapy didn’t see a decrease in [cardiac arrest] or stroke coupled with considerably less benefit on mortality.”
Recently, Medical News Today ran a Spotlight feature around the debate surrounding testosterone therapy, with physicians incompatible on when such treatment methods are appropriate and just what its risks and benefits are.
Taking care of of the debate continues to be whether testosterone therapy could be dangerous. Captured, the united states Fda (Food and drug administration) up-to-date testosterone trademarks to incorporate an alert in regards to a possible elevated chance of cardiac problems.
However, because of the many patients involved and the size of its lengthy follow-up period, the findings from the new study might be influential.
Within the study, a small group of scientists examined health outcomes for males with recorded lower levels of testosterone aged 50 and above who received treatment in Veteran Matters medical facilities between 1999 and 2014.
The men were categorized into one of three groups:
- Group 1: men who were treated until their testosterone levels returned to normal
- Group 2: men who were treated whose testosterone levels did not return to normal
- Group 3: men who did not receive testosterone replacement treatment whose levels remained low.
Across the groups, the average follow-up period ranged from 4.6 to 6.2 years.
Men successfully treated with testosterone 56% less likely to die during follow-up
The scientists ensured that men concentrating on the same health profiles were active in the study, and therefore fair evaluations might be made between your groups. Additionally, the research excluded patients with past stroke or heart attack, even though it did include patients with existing cardiovascular disease.
Between the men in Group 1 whose testosterone levels returned normal and the men in Group 3 whose low testosterone was untreated, a significant contrast in health outcomes was observed. The men who received treatment were 56% less likely to die, 24% less likely to have a heart attack and 36% less likely to have a stroke than those who were untreated.
Similar differences were observed between Group 1 and the men in Group 2 – who received treatment but whose testosterone levels did not return to normal – but not to the same degree as between Groups 1 and 3.

There is little improvement in the connection between Groups 2 and three, aside from individuals who received treatment getting a rather reduced chance of all-cause mortality in comparison with individuals who have been untreated.
The scientists condition the systems behind these effects remain speculative and much more scientific studies are needed. They claim that potential factors include excess fat, blood insulin sensitivity, bloodstream platelets, fats and inflammation.
However, regardless of the results recommending that patients could derive take advantage of testosterone substitute therapy, co-author Dr. Rajat Barua – from the Might (Mo.) Veteran Matters Clinic – states that there has to be “appropriate screening, selection, dosing, and follow-from patients to maximise the advantage of testosterone therapy.”
Several physicians presently think that if testosterone therapy may benefit someone – even when an connected medical problem isn’t apparent – such treatment methods are justified. The authors from the study condition that off-label utilization of testosterone is an issue, which testosterone substitute therapy must only be utilized for males who’ve an connected medical problem.
