Takotsubo cardiomyopathy

Essential points for quick revision.

!
Escalate

Takotsubo cannot be diagnosed safely from the story or ECG alone. New chest pain, ST change, shock or malignant arrhythmia follows the emergency ACS pathway until coronary occlusion and other lethal alternatives are excluded.

Synopsis

Treat the initial ACS mimic safely, confirm transient non-coronary-pattern dysfunction and manage obstruction, shock and thromboembolism.

  • Takotsubo is transient LV and/or RV dysfunction, often beyond one coronary territory, after emotional, physical or neurological stress—but a trigger is not required.
  • It commonly affects postmenopausal women but can occur in any adult; do not use demographics to dismiss ACS.
  • ECG changes and troponin rise are common; coronary angiography is often needed because MI remains the immediate competing diagnosis.

Key red flags

Complicated syndrome

Pulmonary oedema, shock, ventricular arrhythmia, high-grade block, RV failure or embolic signs require critical-care cardiology.

Investigation priorities

01
Serial ECG and high-sensitivity troponinFirst step

Run the ACS pathway and identify evolving repolarisation/QT risk.

Management branches

Front doorPossible Takotsubo

Acute chest pain/dyspnoea with ECG change or troponin rise.

  1. Activate the ACS pathway: ABCDE, ECG within 10 minutes, troponin, monitoring, aspirin if not contraindicated and immediate reperfusion assessment when indicated.
  2. Obtain urgent echo but do not use a ballooning pattern to delay coronary angiography in an unstable or STEMI-pattern presentation.
RecoveryDischarge and confirmation

Stable after acute complications are controlled.

Key medicines

Aspirin300 mg orally once as soon as possible for suspected ACS, unless contraindicated; maintenance depends on the final coronary diagnosis.
