Severe chest pain after an emotional argument resulted in the admission of a healthy 72-year-old woman. She was haemodynamically compromised, with an electrocardiogram (ECG) demonstrating anterior ST-depression and T-wave inversions (Fig. 1). Her 6-hour troponin T level was 132 ng/L. Cardiac catheterisation revealed unobstructed coronary arteries and a reduced left ventricular ejection fraction (LVEF) of <35%, with basal hyperkinesia and apical segment ballooning (Figs 2 - 5). She was discharged home after 3 days of supportive therapy. At 3 months she was asymptomatic, with an equilibrium radionuclide angiography scan revealing a normal heart with an LVEF of 73%.
First described in Japan in 1990, apical ballooning syndrome accounts for 1 - 2% of suspected acute myocardial infarctions globally.[1,2] Often preceded by an emotional or physical stressor, the syndrome is characterised by transient left ventricle dysfunction and electrographic changes that mimic acute myocardial infarction with minimal release of myocardial enzymes in the absence of obstructive coronary artery disease.[3] Although 90% of all reported cases have been in postmenopausal women, it does occur across age and gender boundaries.[4] The exact pathophysiological basis of the disease still has to be demonstrated. Recognition of the syndrome is important because of its favourable natural history and the use of only supportive therapy.
