Cardiogenic shock caused by Takotsubo syndrome complicated with severe anxiety

Rationale Takotsubo syndrome (TTS) is characterized by transient and reversible left ventricular systolic dysfunction, which are often associated with acute physical or emotional stressors. Cancer is one of the comorbidities in TTS, and TTS is even considered as a paraneoplastic syndrome, but its mechanism remains unclear. We report a patient in whom cancer and untreated mental disorders triggered TTS. Patient concerns A 59-year-old man was transferred to the Department of Cardiology because of acute onset of severe chest pain and dyspnea before cystoscopy. He presented with hematuria, had been diagnosed with a high-grade urothelial bladder cancer, and underwent transurethral resection of bladder tumors 4 months previously. He had severe anxiety regarding recurrence and death from cancer, especially after the hematuria recurred. Diagnosis TTS and severe anxiety. Interventions The results of coronary angiography, a left ventriculogram, echocardiography, and the clinical outcome led to the diagnosis of TTS. The patient was treated with extracorporeal membrane oxygenation support, mechanical ventilation, and drugs for heart failure and anxiety. Outcomes Echocardiography showed normal wall motion on day 6 of symptom onset. Six months after symptom onset, the anxiety score was reduced from 12 to 11, and the patient had no episodes of any discomfort, and no evidence of cancer recurrence was observed. Lessons Patients with cancer and TTS have a higher level of stress, and physicians need to pay more attention to early screening and early treatment of mental disorders in these patients. Prompt and effective multidisciplinary treatment, including psychological counseling and antianxiety drugs, can improve the prognosis in such cases.
