Key result
Painless Takotsubo syndrome triggered by acute COPD exacerbation yields ~71% complete ventricular recovery.
Why the study?
Takotsubo syndrome as a manifestation of acute COPD exacerbation is uncommonly reported, and presentation without typical chest pain poses a diagnostic challenge in patients with an apparent clinical justification for their dyspnea.
Observational (n=7)

Takotsubo syndrome triggered by acute COPD exacerbation can present entirely without typical chest pain, underscoring the importance of systematic ECG and cardiac biomarker screening to detect occult myocardial dysfunction in severe respiratory decompensation.
Takotsubo syndrome (TS) as a manifestation of acute chronic obstructive pulmonary disease (COPD) exacerbation is uncommonly reported. Emotional and adrenergic stress, hypoxemia, negative intrathoracic pressure, and the use of beta-agonists are frequently implicated in triggering myocardial dysfunction in this setting. We present a retrospective study of seven cases of TS in patients with COPD exacerbation in which none reported typical chest pain, representing a diagnostic challenge in patients with an apparent clinical justification for their dyspnea. All patients had electrocardiographic changes and elevated cardiac biomarkers, underwent echocardiography and coronary angiography or coronary computed tomography angiography, and received a confirmed diagnosis of TS. Five patients achieved complete recovery of ventricular function, one had partial recovery, and one died during hospitalization due to refractory ventricular arrhythmia. Systematic use of electrocardiography and cardiac biomarkers in COPD exacerbation enabled early diagnosis and appropriate management in the absence of typical angina.

Kirchenchtejn et al. (2026) conducted an observational in Takotsubo syndrome triggered by acute exacerbation of chronic obstructive pulmonary disease (COPD) (n=7). Acute COPD exacerbation with high-dose bronchodilator and corticosteroid exposure was evaluated on Complete recovery of left ventricular function (LVEF ≥ 50% with resolution of regional wall motion abnormalities). Painless Takotsubo syndrome triggered by acute COPD exacerbation resulted in complete ventricular recovery in 5 of 7 patients, partial recovery in 1, and 1 in-hospital death.
