- Hypertrophic cardiomyopathy (HCM) is a major cause of sudden cardiac death (SCD) in the young. We aimed to characterize detailed family history, symptoms, hospital utilization and ECG changes before SCD.We extracted all cases suffering SCD with HCM from the SUDDY cohort, which includes all cases of SCD between 2000-2010 in Sweden among individuals aged 0-35 years along with their controls. We gathered data from mandatory national registries, autopsy reports, medical records, ECGs (including military conscripts), and detailed family history from an interview-based questionnaire (with relatives, post-mortem).Thirty-eight cases (7 female), mean age 22 years, with HCM were identified. Among these, 71% presented with possible cardiac symptoms (chest pain [26%], syncope [22%], palpitations [37%]), before death; 69% received medical care (vs 21% in controls) within 180 days before death. The majority (68%) died during recreational activity (n = 14) or exercise/competitive sports (n = 12). Fifteen (39%) had a known cardiac disorder prior to death, with HCM being diagnosed pre-mortem in nine cases. 58% presented with abnormal ECG recordings pre-mortem, and 50% had a positive family history (1st-3rd generation) for heart disease.In this comprehensive, nationwide study of SCD due to HCM, 87% (33/38) of cases had one or more abnormality prior to death, including cardiac symptoms, a positive family history, known cardiac disease or ECG abnormalities. They sought medical care prior death, to a larger extent than controls. These findings suggest that cardiac screening should be expanded beyond competitive athletes to aid SCD prevention in the young population with HCM.

- Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiacdisease explaining about 4% of sudden cardiac death (SCD) cases among the youngin Sweden. The aim of this study was to describe the circumstances preceding SCDdue to ARVC in all victims <35 years of age who received an autopsy-confirmeddiagnosis of ARVC from January 1st, 2000 to December 31st, 2010 in Sweden (n=22).Data on demographics, medical and family history, circumstances of death, andanatomopathological findings were collected from several compulsory national healthregistries, clinical records, family interviews, and autopsy reports. Registry-based datawas compared with age-, sex- and geographically-matched population controls. Duringthe 6 months preceding SCD, 15 cases (68%) had experienced symptoms of cardiacorigin, mainly syncope or presyncope (54%), and chest discomfort (27%). Eight cases(36%) had sought medical care due to cardiac symptoms. The occurrence of hospitalvisits was significantly increased in cases compared with controls (OR 4.62 [1.35-15.8]). Ten cases (45%) had a family history of SCD. The most common activity at thetime of death was exercise (41%). Complete cardiac investigation was seldomperformed, only one case was diagnosed with ARVC before death. In conclusion, inthis nationwide study we observed a high prevalence of symptoms of cardiac origin,health-care utilization, and family history of SCD preceding SCD due to ARVC amongthe young. Increased awareness of these warning signals in the young is critical toimprove risk stratification and early disease detection.

- Aims: To study the frequency, etiology, and premortal abnormalities in exercise-related sudden cardiac death (SCD) in the young in Sweden. Methods: All subjects with SCD in 10–35-year olds in Sweden during 2000–10, were included (n = 514). Information about each case was retrieved from death certifications, autopsy- and medical records. The number of SCD in athletes was compared to national figures from 1992-99. Results: Exercise-related SCD occurred in 12% (62/514) of the SCD-population, a majority being men (56/62; 90%). Cardiopulmonary resuscitation (CPR) was started in 87% (54/62). In total, 48% (30/62), had a cardiac diagnosis, symptoms, family history and/or ECG-changes, before the fatal event. The most prevalent autopsy diagnosis was sudden arrhythmic death syndrome (15/62; 24%). The frequency of hypertrophic cardiomyopathy (HCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC) was significantly higher in exercise-related SCD compared to non-exertional SCD. Exercise-related SCD was more common in athletes (21/29) than in non-athletes (41/485) (P < 0.0001). The total number of SCDs/year in athletes 15–35 years old, are approximately halved in 2000-10 compared to the years 1992–99. Conclusion: The increased risk of exercise-related SCD in HCM and ARVC underlines the importance of early detection and eligibility recommendations. There is a major reduction in deaths among athletes in the 2000s, compared to the previous decade. These results may partly be explained by improved acute preparedness for sudden cardiac arrest (CPR, defibrillation), but as a substantial percentage have preceding risk factors, such as symptoms and ECG-abnormalities, increased cardiac screening and increased general awareness, may also play a role.

- Aims: To study the incidence and aetiology of sudden cardiac death (SCD) in 1-to 35-year-olds in Sweden from 2000 to 2010.Methods and results: We used the database of the Swedish National Board of Forensic Medicine and the Swedish Cause of Death Registry and identified SCD cases by review of forensic files and death certificates. We identified 552 individuals with SCD in 1-to 35-year-olds; 156 (28%) were women. In 393 (71%), a forensic autopsy had been performed; in 131 (24%), a clinical autopsy had been performed; in 28 (5%) with no autopsy, a cardiac disease was diagnosed before death. The incidence of SCD per 100 000 person-years was 1.3 in 1- to 35-year-olds and 1.8 in 15- to 35-year-olds. In women, the incidence rates yearly decreased during the study period by 11% (95% confidence interval 6.6-14.2). The most common aetiology in 1- to 35-year-olds was sudden arrhythmic death syndrome (31%) and coronary artery disease (15%). In cases with forensic autopsy, death occurred during daily activity (48%), sleep (38%), and physical activity (14%); death was unwitnessed in 60%. Co-morbidity in 15- to 35-year-olds, e.g. psychiatric disorder, obesity, or diabetes, was present in 93/340 (27%) (73 men).Conclusion: The incidence of SCD among 1- to 35-year-olds in Sweden during 2000-10 was 1.3 per 100 000 person-years (28% women); incidence was decreasing in women. Sudden arrhythmic death syndrome was the most common diagnosis. Co-morbidity such as psychiatric disorders and obesity was common among men.
