Cardiac sudden death in adults.

Sudden death is becoming a matter for concern as this type of accident represents an increasing proportion of deaths from cardio-vascular causes. A campaign is being launched aimed at promoting early diagnosis and appropriate action at the time of the event itself. At the same time it is necessary to get to know the target population better, especially with regard to the specific anatomical conditions which are the cause of death. For the last seven years we have been carrying out a descriptive pathological research study. The first stage took form of a three year retrospective study (1989-1991) involving 365 subjects victims of sudden death. The second part was a prospective study carried out in 1994. Heart disease emerged as the principal cause of death, something which is already well known. More interesting was the discovery that 72,3% of the subjects were completely asymptomatic despite the fact that in 85% of cases they had bi-truncal or tri-truncal lesions. The same findings emerged from the study of a subgroup of persons who had died suddenly as a result of acute stress. The data obtained are extremely homogeneous. When compared to the findings obtained from a control group of the same age who had died as the result of violence, the difference between the two populations is highly significant. Finally we should like to draw attention to the lack of epidemiological data on sudden death available in France at the present time, and this despite the fact that it is undoubtedly a public health priority. There is a need to promote both education and action in relation to this somewhat disturbing subject.
