“Cardiovascular Outcomes of Low Testosterone”
This study plans to learn more about heart and vascular aging in men. In some men as they get older, testosterone levels fall below the normal range for young men. Also, as men get older cardiovascular health worsens. This can lead to high blood pressure and heart disease. In this study we want to find out what causes cardiovascular health to worsen in older men. Also we want to find out what happens when testosterone levels are lowered for a short time. Specifically, we want to see if the reduction in cardiovascular health in older men with low testosterone levels is because of damage to mitochondria. Mitochondria are the main power supply of the cells in our body. The results from this study will help to understand why cardiovascular health declines in older men with low testosterone levels compared to younger men and older men who have higher testosterone levels. Knowing this information will help to develop therapies to prevent heart disease in men.
