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.
尽管众多随机研究表明,睾酮替代疗法(TRT)可改善高危患者及已确诊心血管疾病(CVD)患者的中期预后,但主要来自登记处和观察性研究的结果提示,接受超治疗剂量睾酮的老年男性心血管风险增加。近期的荟萃分析表明,在已有心血管疾病的患者中使用睾酮时,对疾病的影响要么有益,要么呈中性。在性腺功能减退和性腺功能正常的男性中也报告了类似结果。两项针对体弱老年男性的睾酮治疗试验报告了相反的结果。分析欠佳的数据库报告称,使用睾酮会增加心血管事件风险。最近,一项基于人群的研究表明,性腺功能减退男性接受睾酮替代治疗不会增加心血管风险。来自对照临床试验的现有数据表明,老年男性使用睾酮不会增加心血管风险或事件风险。对患有CVD、心绞痛或心力衰竭的男性进行的研究报告称,无论是否患有性腺功能减退,睾酮替代治疗对男性都有益处。因此,目前TRT对老年男性的心血管益处大于风险。这在已有CVD的男性中尤为明显。
