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.
- Echo must look for the wall-motion pattern, LV outflow obstruction, MR, RV involvement and apical thrombus.
- CMR helps exclude infarction and myocarditis and usually shows oedema without infarct-pattern late enhancement.
- Shock management depends on mechanism: pump failure, dynamic LVOTO, acute MR, RV failure and arrhythmia require different treatment.
- Apical ballooning with severe akinesis can form LV thrombus and embolise; use contrast imaging when the apex is unclear.
- Repeat imaging should demonstrate recovery; persistent dysfunction or scar requires diagnostic reconsideration.
Key red flags
Pulmonary oedema, shock, ventricular arrhythmia, high-grade block, RV failure or embolic signs require critical-care cardiology.
Dissection, pulmonary embolism, myocarditis, pheochromocytoma crisis and spontaneous coronary dissection remain important alternatives.
Investigation priorities
Run the ACS pathway and identify evolving repolarisation/QT risk.
