Abstract:
Although numerous randomized studies have shown that testosterone replacement therapy (TRT) improves intermediate outcomes in patients at risk and in those with proven cardiovascular disease (CVD), results derived mainly from registries and observational studies have suggested an increased cardiovascular risk in elderly men receiving often supra-therapeutic doses of testosterone. Recent meta-analyses have shown that when testosterone has been used in patients with pre-existing cardiovascular conditions, the effect on the disease has been either beneficial or neutral. Similar results have been reported in hypo- and eugonadal men. Contrasting results have been reported by two trials of testosterone treatment in frail elderly men. Reports from poorly analyzed databases have reported an increased risk of cardiovascular events with testosterone use. More recently, a population-based study showed no increased cardiovascular risk of testosterone replacement in hypogonadal men. Available data from controlled clinical trials suggest that the use of testosterone in elderly men does not increase cardiovascular risk nor the risk of events. Studies in men with CVD, angina, or heart failure report a benefit from testosterone replacement in men with or without hypogonadism. Therefore, at present, the cardiovascular benefits of TRT in elderly men outweigh the risks. This is particularly evident in those men with pre-existing CVD.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
