Risk of cardiovascular disease in family members of young sudden cardiac death victims.


Department of Epidemiology Research, Statens Serum Institut, Copenhagen S, Denmark.


AimsDescriptive and genetic studies suggest that relatives of sudden cardiac death (SCD) victims have an increased risk of several cardiovascular diseases (CVDs). Given the severe consequences of undiagnosed CVD and the availability of effective treatment, the potential for prevention in this group is enormous if they do have an increased CVD risk. This nationwide prospective population-based cohort study described the risk of CVDs in relatives of young SCD victims, compared with the general population.Methods and ResultsAll SCD victims aged 1-35 years in Denmark, 2000-2006, were identified (n = 470), along with their first- and second-degree relatives (n = 3073). We compared the incidence of CVD in those relatives with that in the background population using standardized incidence ratios (SIRs). The observed number of CVDs over 11 years of follow-up was 292, compared with 219 expected based on national rates [SIR 1.33, 95% confidence interval (CI) 1.19-1.50]. Risks varied significantly with age; the SIR for those <35 0.75-1.10="0.75-1.10" 0.91="0.91" 1.35-1.89="1.35-1.89" 1.59="1.59" 2.65-4.69="2.65-4.69" 3.53="3.53" 35-60="35-60" aged="aged" and="and" ci="ci" compared="compared" for="for" of="of" or="or" sirs="sirs" those="those" was="was" with="with" years="years">60 years, respectively (P(homogeneity) < 0.0001).
