Substance Withdrawal-Associated Takotsubo Cardiomyopathy: A Review of the Literature.

Objective: To better understand Takotsubo cardiomyopathy, a rare but life-threatening complication of acute substance withdrawal.Data Sources: A PubMed search was conducted to identify relevant case reports through 2021 using the medical subject headings alcohol withdrawal, opioid withdrawal, benzodiazepine withdrawal OR withdrawal AND Takotsubo OR stress cardiomyopathy.Study Selection: Case reports were included in the review if there was a diagnosis of Takotsubo cardiomyopathy in the setting of withdrawal from substances of abuse. Case reports were excluded if patients were withdrawing from other substances, actively intoxicated, or had myocardial ischemia.Data Extraction and Synthesis: Data were manually abstracted for the variables of interest, including demographics, symptoms, medical evaluation, and treatment. Descriptive statistics of the demographics, symptoms, medical evaluation, and treatment of Takotsubo cardiomyopathy were analyzed.Results: The mean (SD) age of patients experiencing withdrawal-associated Takotsubo cardiomyopathy was 50.8 years (15.2), and 64% of patients were female. The most common signs and symptoms were tachycardia (60%), changes in blood pressure (48%), altered mental status (48%), dyspnea (32%), nausea or vomiting (28%), and chest pain (28%). All patients with a reported electrocardiogram (92%) demonstrated ECG abnormalities; 76% had an elevated troponin level, and 24% had an elevated CK-MB level. Medications that could treat withdrawal and α2-agonists were utilized for 60% and 12% of patients, respectively. Ventilator support, cardiopulmonary resuscitation, and intra-aortic balloon pump were needed for 24%, 8%, and 8%, respectively, of patients with withdrawal-associated Takotsubo cardiomyopathy.Conclusions: Withdrawal-associated Takotsubo cardiomyopathy is a rare but potentially life-threatening complication of substance withdrawal. Clinicians should maintain a high degree of clinical suspicion for withdrawal-associated Takotsubo in patients with a history of substance use disorders or physical dependence on benzodiazepines or opioids, as the clinical presentation may be atypical.
