A reminder of Escherichia coli sepsis-induced reversible cardiomyopathy

Cardiomyopathy is a progressive disease of myocardium causing either mechanical or electrical disturbances. Sepsis-induced cardiomyopathy (SICM) is an entity of cardiomyopathy which is reversible in 1â"2 weeks after recovery from sepsis or septic shock. SICM is thought to have unpredictable cumulative mortality towards sepsis but its exact mechanism remains elusive. We report a case of Escherichia coli SICM in a 63-year-old woman presented with sudden onset of dyspnoea on exertion and orthopnoea following nausea, vomiting and diarrhoea after consuming Chinese foods. Transthoracic echocardiogram revealed severely reduced global left ventricular ejection fraction (LVEF) of <20%âwhich returned back to normal LVEF of 57% after 10 days. Subsequent cardiac catheterisation showed non-obstructive coronaries. No specific therapy intended for reversal of SICM presents to date despite current sepsis survival guideline available for haemodynamic support. Initiation of beta blockers after recovery from septic shock has been beneficial.
