Trends in sudden cardiac death mortality in Italy, 2013 –2019

AbstractWe sought to analyse the incidence of sudden cardiac deaths (SCDs) amongst subjects aged less than 39  years in Italy and its time trend between 2013 and 2019. Data regarding cause-specific mortality and population size by sex in 5-year age groups were extracted from the World Health Organization (WHO) mortality database. Decedents reporting the codes I46.1, I45.6, I47.2, I41.9, R09.2 and R96.0 of the International Classification of Disease-10 (ICD-10) coding system, were extracted. The age-adjusted mortality rates (AAMRs), with relative 95% confidence intervals (CIs) stratified by sex, were determined using the direct method. Joinpoint regression analyses were used to identify periods with s tatistically distinct log linear trends in SCD-related death rates. To calculate nationwide annual trends in SCD-related mortality, we assessed the annual and average annual per cent change (AAPC) and relative 95% CIs. Over the study period, 314 deaths [220 males (70.0%) and 94 females] were due to SCD corresponding to a 0.06 per 100,000 per year (0.10 per 100,000 in males and 0.04 per 100,000 in females, respectively). Proportional mortality slightly increased, without reaching the statistical significance (p = 0.82) from 3.06 to 3.56 per 100 deaths, with a similar trend in both sexes. Joinpoint regression analysis revealed a plateau in age-standardised SCD-related mortality over the period [AAPC: −4.2 (95% CI: −24.0 to 20.8,p = 0.71], which was consistent between m...
