Dear celine,
"Enlarged heart" is not strictly a medical term and could mean several different things. Most likely the coroner was refering to a condition called hypertrophic cardiomyopathy (HCM or HCOM). There are many postings on this site concerning this condition. In brief it is a genetic condition that results in thickening of the heart muscle and increased risk of sudden death. It may not be apparent on physical exam and individuals may have no symptoms. If this is indeed the diagnosis her children are at risk of having this condition and should be screened with an ECG at least an possibly an echocardiogram.
Was the woman athletic? Was she over weight?
If there are no symptoms prior to death and no indicators in familial history, how can doctors confidently tell people not to worry about this?
