Higher testosterone tied to lower heart risks


(Reuters Health) – Elderly men with naturally higher levels of testosterone may be less likely to suffer a heart attack or stroke than those with lower levels of the hormone, a new study finds.


Researchers found that of 2,400 Swedish men in their 70s and 80s, those with the highest testosterone levels were less likely to have a heart attack or stroke over the next several years than men with the lowest levels.


Of 604 men in the bottom quarter for levels of the “male” hormone at the study’s start, 21 percent had a heart attack, severe chest pain or stroke over roughly five years.


That compared with roughly 16 percent of the 606 men who started out with the highest testosterone levels.


But the findings, reported in the Journal of the American College of Cardiology, do not prove that testosterone, itself, deserves the credit.
