A new multi-year study from the Intermountain Medical Center Heart Institute shows that testosterone therapy helped elderly men with low testosterone levels and pre-existing coronary artery disease reduce their risks of major adverse cardiovascular events — including strokes, heart attacks, and death.

The conclusions:

  • After one year, 64 patients who weren’t taking testosterone supplements suffered major adverse cardiovascular events, while only 12 who were taking medium doses of testosterone and nine who were taking high doses did.
  • After three years, 125 non-testosterone-therapy patients suffered major adverse cardiovascular events, while only 38 medium-dose and 22 high-dose patients did.

“Although this study indicates that hypo-androgenic men with coronary artery disease might actually be protected by testosterone replacement, this is an observational study that doesn’t provide enough evidence to justify changing treatment recommendations,” Dr. Muhlestein said. “It does, however, substantiate the need for a randomized clinical trial that can confirm or refute the results of this study.”

The new Intermountain Medical Center Heart Institute study corroborates the findings of a 2015 Intermountain study, which found that taking supplemental testosterone didn’t increase the risk of experiencing a heart attack or stroke for men who had low testosterone levels and no prior history of heart disease.
