To determine, by means of autopsy, the cause of death following unsuccessful cardiopulmonary resuscitation of patients with a witnessed prehospital cardiac arrest of unclear origin. Observational study of all prehospital-witnessed cardiac arrest of unclear origin over a period of 19 months in the emergency medical service region of a tertiary care hospital. During the study period, 211 prehospital cardiopulmonary resuscitation attempts were recorded. In 144 study participants, cardiopulmonary resuscitation was not successful: there was no return of spontaneous circulation. Cardiac arrest of traumatic or other clear origin was not considered, nor were paediatric cases. Thirty out of the 114 remaining patients underwent an autopsy (26.3%). The main aetiology of cardiac arrest in this selected population was ischaemic heart disease in 16 out of 30 patients (53.3%) followed by pulmonary embolism in four patients (13.3%) and vascular disease other than coronary disease in two patients (6.7%). Other causes consisted of hypertrophic obstructive cardiomyopathy (one patient) (3.3%) and poisoning (one patient) (3.3%). The cause of death could not be identified in six cardiac arrest victims (20%). Ischaemic heart disease and pulmonary emb...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.


Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.


Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
