According to a report from Reuters, elderly male with a high tester one level has a lower risk of heart attack compared to their counterpart with lower levels of the same hormone.
Findings can be read in the Journal of the American College of Cardiology. The study showed that of 2,400 Swedish men in their 70s and 80s, who has the highest testosterone levels not endangered of suffering a heart attack or stroke in the near future than men with the lowest levels.
However, there is no scientific evidence that the testosterone levels deserve the credit as there a lot of factors that are at work. Researchers do not recommend the immediate replacement of testosterone in lowering the risk of heart attacks.
The guy who leads the study is Asa Tivesten from Sahlgrenska University Hospital in Goteborg, Sweden. Tivesten says that all they have proven right now is that older men with high testosterone levels relatively sheltered against cardiovascular events and consequently lower testosterone signifies an increased cardiovascular risk.
Almost all the serious health condition is capable of lowering testosterone levels, as can obesity. However, the researchers look for a number of health factors that include men’s weight, blood pressure and any diagnoses of diabetes, heart disease or stroke at the beginning.
Of 604 men in the bottom quarter for levels of the “male” hormone at the study’s start, 21 percent suffered a heart attack, severe chest pain or stroke for approximately five years.
The results can be compared to almost 16 percent of the 606 men who began with the highest testosterone levels.
Even if, the researcher has accounted for health factors, men in the highest-testosterone crowd even showed a 30 percent lower risk of heart disease or stroke than those people with the other three-quarters of the study group.
JoAnn Manson, chief of preventive medicine at Brigham and Women’s Hospital in Boston believe the rule does not mean that something other than testosterone may be at work. Manson not involved in the study.
According to her, some possible reason why higher testosterone levels means less likely to suffer from a heart attack is that people with high testosterone level are those who are lean.
She added that there should be clinical trials that are going to back up the study, as it could indicate whether testosterone replacement in older men needed or not.
She noted that currently such trials are ongoing. The outcomes can be varied on whether testosterone replacement gets better “intermediate” results like cholesterol or blood sugar levels.
