Methylenedioxymethamphetamine (ecstasy)-related myocardial hypertrophy: an autopsy study.

BACKGROUND

Myocardial hypertrophy is a well-recognized complication of cocaine and methamphetamine abuse and is a strong, independent risk factor for sudden death, myocardial infarction, and congestive heart failure. We sought to determine if use of MDMA (methylenedioxyamphetamine or "ecstasy") is associated with myocardial hypertrophy at death.

METHODS AND

RESULTS

A matched, retrospective study using medical examiner (ME) death reports. Consecutive MDMA positive (+) and MDMA negative (-) deaths identified from MEs in 10 states and a local county, respectively. Five MDMA(-) cases were matched to each MDMA(+) case for age, sex, and ethnicity. MDMA(+) cases were confirmed using GC/MS and other drugs of abuse (e.g., cocaine and methamphetamine) were absent. Matched MDMA(-) cases were trauma fatalities with intact hearts and blood negative for all illicit stimulants. Cardiac weights were compared between the two groups. Twenty seven MDMA(+) deaths and 135 matched MDMA(-) deaths were enrolled. Mean age was 20 years (range 16--33 years); 44% were female. 70.4% were Caucasian, 14.8% African-American, 11.1% Asian, and 3.7% Hispanic. Mean heart weight of MDMA(+) fatalities was 315.7 and 277.2g for MDMA(-) fatalities (Diff=38.5 g; 95% CI=18.3--8.7). Multivariate analysis revealed that MDMA(+) fatalities were more likely to have an enlarged heart (OR=18.3; 95% CI=3.6--1.6).

CONCLUSION

The findings of this study suggest that MDMA users might also be at risk for myocardial hypertrophy and possible cardiac toxicity, similar to other stimulants.
