Key result
Takotsubo syndrome develops after successful PCI with LVEF recovering to 59% at two months.
Why the study?
Takotsubo syndrome after PCI is rare, and its clinical characteristics are easily confused with complications following PCI.
Case Report (n=1)
No
This case highlights the importance of considering Takotsubo syndrome in the differential diagnosis of patients presenting with unexplained ECG changes and troponin elevation following successful PCI.
Consider Takotsubo in post-PCI ECG/troponin changes; single case leaves open incidence and screening needs.
BACKGROUND: Takotsubo syndrome (TTS), which is frequently secondary to severe emotional (fear, anxiety, etc.) or physical stress, is an acute reversible heart failure syndrome characterized by temporary left ventricular regional systolic dysfunction. Nevertheless, TTS after percutaneous coronary intervention (PCI) is rare, and its clinical characteristics are easily confused with complications after PCI. CASE PRESENTATION: This article reports a case of TTS induced by psychological and physical pressure after successful PCI in our institution. The patient had symptoms comparable to complications after PCI, including V1-V5 ST segment elevation and T wave changes of electrocardiogram (ECG) and troponin elevation. Coronary angiogram, left ventricle opacification (LVO), and cardiac magnetic resonance (CMR) were performed to exclude postoperative complications. Diagnosis of TTS was eventually achieved. CONCLUSION: We cannot dismiss the risk of TTS in patients who have unexplained V1-V5 ST segment elevation and T wave changes of ECG and troponin elevation following successful PCI. Meanwhile, medical personnel should provide mental, cultural, and emotional services to patients in addition to essential diagnostic and treatment technical services during the perioperative period.

Lü et al. (2023) conducted a case report in Takotsubo syndrome (n=1). Percutaneous coronary intervention was evaluated. A 69-year-old female developed Takotsubo syndrome following successful percutaneous coronary intervention, with left ventricular ejection fraction recovering from 51% to 59% at two months after medical therapy.
