988 UNCLEAR SUDDEN DEATH IN THE YOUNG: DIFFERENT DISTRIBUTION AMONG THE ITALIAN REGIONS

Abstract

Abstract Introduction Sudden death (SD) in the young due to cardiovascular diseases remains a focus of the public health system. It occurs unexpectedly in apparently healthy people. In addition, several of the diseases that cause sudden death in the young can be diagnosed and treated prior to the first lethal event; on the other hands, a post mortem approach, by the means of clinical autopsy and molecular autopsy, may clarify the underling disease to better develop futher prevention by a familial approach. The attention on this issue has greatly sensitized doctors and public opinion. Aim The aim of the manuscript was to evaluate the frequency of sudden deaths in Italy in the decade 2008-2017. Methods and Data sources The searches were carried out by consulting the database of the National Institute of Statistics (ISTAT). We counted in the ISTAT database all the deceased under the age of 40 due to unclear causes in the decade 2008-2017. Results We counted 7159 young patients with DS, unevenly distributed throughout the Italian territory. In detail, 10% (1373) were in the North-West, 14% (988) in the North-East, 13% (934) in the Center, 44% (3178) in the South and 10% (686) in the islands. The analysis showed how the unclear SD in Italy have decreased over time. Southern Italy had the highest number (357) of SD at the start of the observation which slightly dropped to 272 in 2017. Despite this significant reduction, the South remains the place where the largest number of unclear SD are counted. Most likely, the initial studies conducted in the Veneto region sensitized doctors to SD in young people and athletes, leading a wider screening through cardiological examination and electrocardiogram for prevention; furthermore a widespread recurrence to clinical autopsy, to reach a clear diagnosis, allows the awareness that other cases could occur in the same family. Grief coping approach and cultural competency may explain the regional difference. The new methods available to genetics, such as next generation sequency (NGS), have allowed an increase in diagnoses even in the deceased and have identified possible pathogenic genes in family members. Conclusions Sudden death in young people represents an important challenge, considering the number of events that occur in our country and the different distribution in the Italian regions. Medical community need to better address this issue, by implementing both prevention and post-mortem analysis, to reduce the sudden death burden, especially in southern region. Thiene G.
