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.
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).
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.
心肌肥大是可卡因和甲基苯丙胺滥用公认的并发症,是猝死、心肌梗死和充血性心力衰竭的一个强大的独立危险因素。我们试图确定使用摇头丸(亚甲二氧基苯丙胺或“摇头丸”)是否与死亡时的心肌肥大有关。
一项使用法医死亡报告的配对回顾性研究。分别从10个州和一个当地县的法医处确定连续的摇头丸阳性(+)和摇头丸阴性(-)死亡案例。将5例摇头丸阴性(-)案例与每例摇头丸阳性(+)案例按年龄、性别和种族进行匹配。摇头丸阳性(+)案例通过气相色谱/质谱法确认,且不存在其他滥用药物(如可卡因和甲基苯丙胺)。匹配的摇头丸阴性(-)案例为心脏完好且血液中所有非法兴奋剂检测呈阴性的创伤性死亡案例。比较两组的心脏重量。纳入了27例摇头丸阳性(+)死亡案例和135例匹配的摇头丸阴性(-)死亡案例。平均年龄为20岁(范围16 - 33岁);44%为女性。70.4%为白种人,14.8%为非裔美国人,11.1%为亚洲人,3.7%为西班牙裔。摇头丸阳性(+)死亡案例的平均心脏重量为315.7克,摇头丸阴性(-)死亡案例为277.2克(差值 = 38.5克;95%置信区间 = 18.3 - 8.7)。多变量分析显示,摇头丸阳性(+)死亡案例更有可能出现心脏增大(比值比 = 18.3;95%置信区间 = 3.6 - 1.6)。
本研究结果表明,与其他兴奋剂类似,摇头丸使用者也可能面临心肌肥大和潜在心脏毒性的风险。
