A Danish rersearch team investigated the incidence of sudden cardiac death in people with congenital heart defects (SCD-CHD) and whether incidence of SCD-CHD in infants declined after implementation of nationwide fetal ultrasound screening in Denmark.
11,451 deaths among people aged 0 to 35 years in Denmark in 2000 to 2009 were included.
They identified 90 cases of SCD-CHD from 809 cases of sudden cardiax death. The incidence rate of SCD-CHD was 0.4 per 100.000 person-years among people aged 0 to 35 years. In total, 53 were diagnosed with CHD before death. Incidence of SCD was 9.6× higher among patients with CHD compared with people without CHD. Annual incidence of physical activity-related SCD-CHD among patients aged 2 to 35 years diagnosed with CHD was 0.9 per 100.000. The annual incidence rate of SCD-CHD in infants declined after implementation of nationwide fetal ultrasound screening.
