Introduction: Cardiac arrest (CA) is the cessation of cardiac mechanical activity confirmed by the absence of signs of circulation. Data suggest that race and gender could impact the survival rate of CA (1,2). We aim to describe the temporal trend of the age-adjusted mortality rate of gender and race reported as any-mention cause of cardiac arrest death from 1990 to 2019.Methods: The United States statistics mortality data from the CDC WONDER database from 1999 to 2019 were used. The diagnosis of CA was stablished using the ICD-10 codes: I46.0, I46.1, I46.9 and I49.0. Mortality rate was calculated for all ages. Age-adjusted mortality rates per 100000 were calculated using 95% confidence intervals.Results: The study included 7435677 subjects with any-mention of CA death. Most deaths occurred in older individuals (90.7 % of the death reported in those 55 years or older). Cardiac Arrest deaths decreased from 138.1 in 1999 to 91.5 in 2019. Temporal trend depicted a gradual decline in the age-adjusted mortality rate per year (IRR 0.97 95 % CI 0.95 to 0.99). There was a progressive decrease mortality rate across both male (167.6 in 1999 to 110 in 2019 IRR 0.97 95% CI 0.96 to 0.98) and female (117.5 1999 to 76.5 in 2019 IRR 0.97 95% CI 0.96 to 0.98). The age-adjusted mortality rate was significantly higher in males compared to females (126.7 vs 91.3 IRR 1.39 95 % CI 1.27 to 1.52). There was a significant decrease in the mortality rate through 1999 to 2019 seen in all the races.Conclusions: There was an association in the CA mortality rate that persisted over the years favoring male over females. The Black race had the highest mortality rate among the races. American Native had the lowest mortality rate. The phenomenon underlying the race difference is not fully understood (3). Quality-improvement efforts have been associated with improvement of survival (4,5). The present data demonstrates a gradual decline of CA-related mortality associated with significant high gender and racial disparities.
