Unexplained Death

Context: Sudden cardiac death (SCD) in a young athlete is a tragic event and is the leading medical cause of death in this population. The precise incidence of SCD in young athletes has been subject of debate, with studies reporting drastically different rates (1:917,000 athlete-years (AYs) to 1:3000 AYs) depending on the methodological design of the investigation or the targeted population. Evidence Acquisition: A literature search was performed in PubMed using the terms: incidence, sudden cardiac death, sudden death, sudden cardiac arrest, etiology, pathology, registry, athlete, young, children, and adolescents. Articles were reviewed for relevance and included if they contained information on the incidence of SCD in athletes or young persons up to the age of 35 years. Study Design: Clinical review. Level of Evidence: Level 5. Results: Studies of high quality and rigor consistently yield an incidence of 1:50,000 AYs in college athletes and between 1:50,000 and 1:80,000 AYs for high school athletes, with certain subgroups that appear to be at particularly high risk, including the following: men, basketball players, and African Americans. Initial reports suggest that the most common cause of SCD is hypertrophic cardiomyopathy (HCM). However, more comprehensive investigations in the United States and international populations—athletes, nonathletes, and military—support that the most common finding on autopsy in young individuals with SCD is actually a structurally normal heart (autopsy-negative sudden unexplained death). Conclusion: SCD is the leading cause of death in athletes during exercise and usually results from intrinsic cardiac conditions that are triggered by the physiologic demands of vigorous exercise. Current rates of SCD appear to be at least 4 to 5 times higher than previously estimated, with men, African Americans, and male basketball players being at greatest risk. Emerging data suggest that the leading finding associated with SCD in athletes is actually a structurally normal heart (autopsy-negative sudden unexplained death).

The Subject

Psychotropic drug use has long been associated with sudden unexplained and unexpected death in psychiatric patients despite controversies surrounding the issue. Physical restraint following violent episodes in psychiatric in-patients is also associated with neurally mediated sudden cardiac death. A case where these two mechanisms have jointly resulted in sudden death is reported. The literature on the subject is reviewed and the measures which may be useful in reducing the incidence of such deaths are discussed. The need for accurate and detailed reporting of such cases is emphasized.

Postmortem Genetic Testing

Postmortem analysis of young sudden cardiac death patients leads to a diagnosis of structural cardiac disease in the majority of cases. However, despite thorough autopsy, including toxicological and histological analysis, in one-third of patients no cause of death is identified and these patients are classified as sudden unexplained death or sudden arrhythmic death syndrome. Postmortem genetic testing in these patients can establish a genetic aetiology of sudden cardiac death, which allows for appropriate screening and management of family members at risk of sudden cardiac death.

In Infants And Children

ObjectivesSudden unexplained death in children is a tragic and traumatic event, often worsened when the cause of death cannot be determined. This work aimed to investigate the presence of putative pathogenic genetic variants in a broad spectrum of cardiomyopathy, channelopathy and aortic disease associated genes that may have increased these children's vulnerability to sudden cardiac death.DesignWe performed molecular autopsy of 41 cases of sudden unexplained death in infants and children through massive parallel sequencing of up to 86 sudden cardiac death-related genes. Multiple in silico analyses were conducted together with a thorough review of the literature in order to prioritise the putative pathogenic variants.ResultsA total of 63 variants in 35 cases were validated. The largest proportion of these variants is located within cardiomyopathy genes although this would have been more expected of channelopathy gene variants. Subtle microscopic features of heart tissue may indicate the presence of an early onset cardiomyopathy as a predisposing condition to sudden unexpected death in some individuals.ConclusionsNext-generation sequencing technologies reveal the existence of a wide spectrum of rare and novel genetic variants in sarcomere genes, compared with that of cardiac ion channels, in sudden unexplained death in infants and children. Our findings encourage further investigation of the role of early onset inherited cardiomyopathies and other diseases involving myocardial dysfunction in these deaths. Early detection of variants in these individuals could help to unmask subtle forms of disease within their relatives, who would eventually benefit from better counselling about their genetic history.

Abstract Introduction Sudden cardiac death (SCD) may be caused by several inherited cardiac diseases and screening and treatment of relatives may be lifesaving. Sudden unexplained death (SUD) victims have been autopsied, whereas non-autopsied possible SCD (pSCD) victims are only filtered on manner of death and medical records. Screening of relatives may identify an inherited cardiac disease. Purpose To assess the diagnostic yield at initial evaluation and during follow-up of relatives to SUD and pSCD victims. Furthermore, to evaluate the outcome in the relatives. Methods We retrospectively included first-degree relatives to SUD and pSCD victims referred to our tertiary center from 2005 to 2018. Probands with known antemortem inherited cardiac disease were excluded. Data from systematic screening and routine follow-up of the relatives were registered. Results We included 371 first-degree relatives from 187 families: 276 SUD relatives (age at initial evaluation 35±17 years, 54% men;) and 95 pSCD relatives (age at initial evaluation 40±15 years, 51% men). The diagnostic yield among SUD families was 18%, among pSCD families 13% (p>0.05 between groups). The diagnoses in SUD families were mainly channelopathies (68%), whereas the pSCD families were diagnosed with cardiomyopathies, channelopathies, and premature ischemic heart disease (Figure 1). The vast majority of diagnosed families (93%) were diagnosed at the initial evaluation and only two families were diagnosed during the mean follow-up of 5.4 years. During follow-up, 57 (15%) relatives had a cardiac-related hospitalization, 12 (3%) relatives had a cardiac device implanted, three (1%) relatives died of non-cardiac causes, and one (0.5%) relative had a myocardial infarction. There was no significant difference in cardiac event rates between the SUD and pSCD groups (all p>0.05). Conclusion One in 6–7 families with SUD or pSCD victims obtained a diagnosis based on screening of relatives; we mainly diagnosed channelopathies in SUD families and a broader spectrum of inherited cardiac disease in the pSCD families. The majority of affected relatives was diagnosed at the initial evaluation and clinical follow-up may not be warranted in all relatives with normal findings at initial screening. Figure 1.
