- Description: Although several drugs are purported to improve exercise performance, androgenic anabolic steroids (AAS) are the most widespread. Furthermore, unlike other drugs, their use has expanded beyond competition, to non-competitive and recreational athletes. Correspondingly health professionals are more likely to come into contact with users of AAS than with users of other performance-enhancing drugs. While there are numerous reports outlining serious cardiovascular consequences to high-dose AAS abuse, this evidence is often limited by difficulties in gaining access to users due to the legal status of AAS. Additionally the co-abuse of other substances (as additional muscle mass enhancers, or to mitigate possible side effects) is a further confounding factor. This review examines the evidence for AAS having a negative effect on the cardiac and vascular tissue and the corresponding risk of developing cardiovascular disease. Possible mechanisms of action by which AAS bring about these changes are also discussed.

- Description: Background: Ageing is associated with an inexorable decline in cardiac and vascular function, resulting in an increased risk of Cardiovascular Disease (CVD). Lifestyle factors such as exercise have emerged as a primary therapeutic target in the prevention of CVD, yet older individuals are frequently reported as being the least active, with few meeting the recommended physical activity guidelines. In contrast, well trained older individuals (Masters athletes) have superior functional capacity than their sedentary peers and are often comparable with young non-athletes. Therefore, the 'masters' athlete may be viewed as a unique non-pharmacological model which may allow researchers to disentangle the inexorable from the preventable and the magnitude of the unavoidable 'true' reduction in cardiac function due to ageing. Conclusion: This review examines evidence from studies which have compared cardiac structure and function in well trained older athletes, with age-matched controls but otherwise healthy. © 2018 Bentham Science Publishers.
