Steroid abuse is rampant in the health and fitness industry. Not only that, but it is common for glamor industries to promote such things as Human Growth Hormone or other seemingly harmless doping agents. Well, wait a minute folks, steroids are not to be taken lightly.

Steroids increase the likelihood of cancer and tumor growth, cause enlargement of the heart, increase your risk of heart attacks, and decrease one's overall conditioning and health. 

New research  confirms such steroids increase the likelihood of heart attacks and limit any increase that would be obtained from a normal heart in VO2 from treadmill exercise.

The results demonstrate for the first time that chronic administration of high doses of AAS (355.4+/-59.47 mg.wk) lead to hemodynamic and metabolic response impairment. In conclusion, the chronotropic significant incompetence in the current study was reflected by an exaggerated hemodynamic response to exercise. Furthermore, the findings suggest that nonusers of AAS showed increases in VO2max when compared to the AAS group. Therefore, this study provides a contraindication to AAS use, especially in those at increased risk of cardiovascular events.
