Abstract:
A woman in her early 70s presented with chest pain, dyspnoea and diaphoresis 30 min after her husband expired in our hospital. Cardiac markers were elevated and there were acute changes in ECG suggestive for acute coronary syndrome. Echocardiogram showed apical akinesis, basal segment hyperkinesis with an ejection fraction of 30%. Cardiac catheterisation was performed showing non-obstructive coronary arteries, leading to the diagnosis of stress-induced cardiomyopathy. The patient improved with medical management. Repeat echocardiogram 2 months later showed resolution of heart failure with an ejection fraction of 65-70%.
