1/2. Is there an association between ephedra and heart failure? a case series.

    BACKGROUND: ephedra is a sympathomimetic commonly used for the purposes of athletic performance enhancement and weight loss. It is known to be associated with gastrointestinal and psychiatric manifestations. We report here on 6 cases of dilated cardiomyopathy associated with ephedra use. methods AND RESULTS: Over a period of 18 months, 6 patients attending our outpatient department with new onset heart failure were noted to have exposure to ephedra. The case record was reviewed and detailed clinical and echocardiographic data were extracted. All 6 patients (4 males) had left ventricular dysfunction at presentation (mean ejection fraction 20 /- 5%) and were treated with conventional heart failure pharmacotherapy. All patients discontinued ephedra use as advised. new york Heart association class improved from class III in 5 patients (class II in 1 patient) to class I, within a median of 6 months (range 3-96). Ejection fraction improved to a mean of 47 /- 6%. CONCLUSIONS: ephedra may be associated with left ventricular systolic dysfunction. Withdrawal of this agent, in conjunction with proven pharmacotherapy, results in a significant improvement in functional status and left ventricular ejection fraction. We recommend specific enquiry into the use of over-the-counter supplements, particularly ephedra and its derivatives, when being evaluated with heart failure symptoms. These cases illustrate the potential risk of ephedra and provide additional support for the recent decision to ban this supplement.

2/2. Dilated cardiomyopathy and acute liver injury associated with combined use of ephedra, gamma-hydroxybutyrate, and anabolic steroids.

    Anabolic-androgenic steroids are synthetic derivatives of testosterone that some athletes have used to enhance muscle mass and improve their athletic performance. ephedrine is a potent sympathomimetic agent that can lead to cardiomyopathy similar to that seen with catecholamine excess. Adverse cardiovascular events attributed to anabolic steroid and ephedra use, such as arrhythmias, myocardial infarction, cardiomyopathy, and sudden death, are rarely reported. Bodybuilders have used gamma-hydroxybutyrate, a potent secretagogue of growth hormone, to promote muscle development. Although dilated cardiomyopathy is a known complication of excess growth hormone levels, it has not been associated with use of gamma-hydroxybutyrate. A healthy 40-year-old man was admitted to our hospital for new-onset congestive heart failure and severe acute hepatitis that developed several months after he began using anabolic-androgenic steroids, ephedra, and gamma-hydroxybutyrate supplements. Analysis with an objective causality assessment scale revealed a probable adverse drug reaction between the patient's use of anabolic steroids, ephedra, and gamma-hydroxybutyrate and the development of his cardiomyopathy and acute liver injury.
