This is another study that supports the appropriate use of testosterone in deficient patients.  It shows that testosterone can decrease cardiovascular disease by up to 30%

A study of 24,000 Medicare patients found that testosterone therapy didn’t increase the risk of heart attack, contrary to several earlier studies, and that it even lowered the risk of heart attack by about 30% in the group of men judged most likely to have one based on other factors.The findings are a boost for proponents of testosterone therapy, but still aren’t likely to settle the long-standing debate over testosterone safety any time soon.Sales of testosterone products have tripled in the last decade, to over $2 billion in 2012, and manufacturers such as Eli Lilly & Co. and AbbVie, formerly part of Abbott Laboratories, have spent millions advertising the benefits of restoring “low T,” including boosting sexual function and muscle tone.

Several studies have linked testosterone use to higher cardiovascular risks in older men. Last year, a study in the Journal of the American Medical Association reported that testosterone raised the risk of death, heart attack and stroke by about 30% in veterans with a history of heart disease.  But critics have attacked the study’s methodology for, among other things, including over 100 women among the 1,132 subjects studied. Over 25 international medical groups have demanded that JAMA retract the article. JAMA has declined to do so.

In the latest study, published online in the Annals of Pharmacotherapy, researchers at the University of Texas Medical Branch used a national Medicare sample and compared the records of 6,355 men who had at least one testosterone injection between 1997 and 2005, with 19,065 non-testosterone users. The testosterone users were no more likely to have a myocardial infarction than the nonusers during the period, according to the study.
