Long-term steroid use damages the heart, research shows

April 27, 2010 |  4:30 pm

Long-term use of anabolic steroids damages the heart more than researchers previously believed and could be setting up many users for heart disease and death, researchers reported Tuesday. The drugs, which include testosterone and related hormones, are taken by weight lifters and other athletes to boost muscle mass. Research reported in the journal Circulation: Heart Failure shows that they can severely impair the heart's ability to pump blood throughout the body.

Previously known side effects of the drugs include liver tumors, jaundice, high blood pressure, shrinkage of the testicles, reduced sperm count, development of breasts, paranoid jealousy, extreme irritability and impaired judgment.Weightlifter

Because some studies have also suggested an effect on the heart, Dr. Aaron L. Baggish of Massachusetts General Hospital in Boston and his colleagues decided to study the effects more carefully. They recruited 12 male weight lifters, average age 40, who reported taking about 675 milligrams of steroids per week for nine years. They were compared with seven closely matched weight lifters who had not taken the drugs.

The researchers used echocardiography to measure the so-called ejection fraction, the proportion of blood in the left ventricle forced out of the heart with each contraction. In healthy people, the ejection fraction is normally somewhere between 55% and 70%. In the steroid-taking group, the average ejection fraction was about 50%, compared to 59% in the group that did not take drugs. Such low ejection fractions are associated with an increased risk of heart disease and heart failure. The steroid users also had significantly impaired diastolic function, impeding the ventricle's ability to relax and fill with blood.

Previous studies have not found such clear-cut problems, Baggish said. That may be in part because they were conducted in Europe and athletes may have been taking different drugs. Also, most previous studies have looked at professional athletes, who might be expected to be healthier, while this one focused on recreational athletes.

"What we hope is that people start recognizing steroid use as a potential cause of heart disease and a cause of otherwise unexplained heart dysfunction in young people," Baggish said in a statement.

Oh I have such strong opinions on the use of steroids especially for children. Our son had severe Eczema and his allergist kept increasing his dose until one day, he became very sick. The doctor who saw him at the hospital informed us that he was steroid dependent and we had to have him immediately weaned off. It was so scary. Thankfully that was what it took for us to realize we needed other options and we soon found Belly Boost probiotics for him and he began to clear up dramatically! It has been such an eye-opening experience for our family and now I just shudder at the thought of steroid use.

The anabolic steroids utilized in this study are different than the one's used by your son..these are steroids taken in pill form, but more so, injected into muscle areas for enhancement. Users will rotate muscle sites depending on the users need. Other steroids such as Prednisone have shown to have great results taken by individuals suffering from polymyalgia. Always get a second opinion if you are unsure of medication prescribed by your physician..especially for children. Research the drug and ask questions before giving it. There are many resources available for parents...Internet, primary physician, pharmacist, etc...
