ABSTRACT
The inflammatory component of ischaemic heart disease (IHD) is well recognised. An elderly male, following primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI), had, otherwise unexplained, severely elevated C-reactive protein (CRP) prior to sudden cardiac death (SCD). Post-mortem showed only old infarct, no re-stenosis, and no evidence of inflammation elsewhere. The levels of CRP in this case are much higher than those documented previously in IHD. Current guidelines advocate for implantable cardioverter defibrillator (ICD) implantation after acute coronary syndrome (ACS) only in the context of left ventricular ejection fraction <35%, therefore, this patient would not qualify. Multiple risk-stratification tools have been developed to widen ICD prescription after ACS, but have not yet been integrated into the National Institute for Health and Care Excellence (NICE) guidelines. This case is a poignant reminder that we must widen ICD prescription, and CRP should be considered as a likely predictor.
