Cardiomyopathy associated with amphetamine-dextroamphetamine (Adderall) use is an emerging and under-recognized clinical concern, particularly in the context of chronic stimulant exposure. While most reported cases involve non-ischemic myocardial dysfunction, the potential for Adderall to accelerate atherosclerosis and contribute to ischemic cardiomyopathy remains unexplored. This case report aims to document the potential severity of Adderall-induced cardiomyopathy with concomitant coronary artery disease (CAD), examine the pathophysiological link between chronic stimulant exposure and accelerated atherosclerosis, and emphasize the need for vigilant cardiovascular monitoring in patients on long-term stimulant therapy. We report the case of a 43-year-old man with no known cardiovascular history who presented with progressive dyspnea and signs of heart failure. He disclosed a five-year history of high-dose Adderall use (45-65 mg daily) and tobacco consumption but had no prior history of hypertension, diabetes, or known CAD. Evaluation revealed a severely reduced left ventricular ejection fraction (10-15%), consistent with dilated cardiomyopathy. Coronary angiography unexpectedly revealed severe three-vessel CAD, necessitating urgent coronary artery bypass grafting (CABG). Postoperative recovery was uneventful, and the patient was initiated on guideline-directed heart failure therapy, with structured follow-up and strict recommendations for stimulant cessation and lifestyle modification. This case illustrates the multifactorial cardiotoxicity of chronic Adderall use, including direct myocardial injury, fibrotic remodeling, vasospasm, and accelerated coronary atherosclerosis. Unlike prior reports of reversible non-ischemic cardiomyopathy, this case required surgical revascularization, underscoring the irreversible nature of the damage in some patients. It uniquely highlights the synergistic contribution of stimulant-induced toxicity and underlying CAD to the development of severe cardiac dysfunction.
与安非他明-右旋安非他明(阿得拉)使用相关的心肌病是一个新出现且未得到充分认识的临床问题,尤其是在长期接触兴奋剂的情况下。虽然大多数报告的病例涉及非缺血性心肌功能障碍,但阿得拉加速动脉粥样硬化并导致缺血性心肌病的可能性仍未得到探索。本病例报告旨在记录阿得拉所致心肌病合并冠状动脉疾病(CAD)的潜在严重性,研究长期接触兴奋剂与加速动脉粥样硬化之间的病理生理联系,并强调对长期接受兴奋剂治疗的患者进行警惕的心血管监测的必要性。我们报告了一例43岁男性病例,该患者无已知心血管病史,出现进行性呼吸困难和心力衰竭体征。他透露有五年高剂量使用阿得拉(每日45 - 65毫克)和吸烟史,但既往无高血压、糖尿病或已知CAD病史。评估显示左心室射血分数严重降低(10 - 15%),符合扩张型心肌病。冠状动脉造影意外发现严重的三支血管CAD,需要紧急进行冠状动脉旁路移植术(CABG)。术后恢复顺利,患者开始接受指南指导的心力衰竭治疗,并进行结构化随访,同时严格建议停止使用兴奋剂并改变生活方式。本病例说明了长期使用阿得拉的多因素心脏毒性,包括直接心肌损伤、纤维化重塑、血管痉挛和加速的冠状动脉粥样硬化。与先前关于可逆性非缺血性心肌病的报告不同,本病例需要手术血运重建,强调了部分患者损伤的不可逆性。它独特地突出了兴奋剂诱导的毒性和潜在CAD对严重心脏功能障碍发展的协同作用。
