Sudden unexpected non-cardiac death in the Genoa Medico-Legal District: A six year study (2014-2019) and literature review

Sudden death is described as a natural but unexpected death occurring within one hour from the onset of the patient’s final symptoms. Despite cardiac disease being recognised as the cause of death in most people, sudden and unexpected death can also be non-cardiac related. Often a natural but sudden death is not subject to an autopsy, but only to an external examination, and this runs the risk of wrongly attributing the death to a cardiac cause. The present review is a retrospective-observational study which looks into the cases of sudden non-cardiac death recorded in the Genoa District (Italy) from 2014 to 2019 and investigated through complete autopsy examinations. Amongst these cases, 39 (31.5%) were attributable to gastrointestinal diseases, mostly due to the rupture of oesophageal varices; 39 (31.5%) to respiratory diseases, especially pulmonary infections; 31 (25%) to peripheral vascular disease, mostly attributable to pulmonary thromboembolisms or the acute dissection of aneurysms whilst the remaining 15 cases (12%) were attributable to intracranial haemorrhages.
