Global, regional and national burden of alcohol cardiomyopathy from Global Burden of Disease Study 2019

This study aimed to provide up-to-date and comprehensive estimates on the global alcohol cardiomyopathy (ACM) from 1990 to 2019. Detailed data on the prevalence, disability-adjusted life-years (DALYs), deaths,percentage change in the number of cases and estimated annual percentage change (EAPC) of ACM worldwide from 1990 to 2019 were obtained or calculated from the Global Burden of Disease Study (GBD) 2019. Globally, the estimated prevalent cases of ACM in 2019 were 707,652 [95% uncertainty interval (UI): 545,182–924,392], with a 35.4% (28.2–44.2) increase from 522,616 (95% UI: 394,118–683,206) in 1990, while the age-standardized prevalence rate (ASPR) was slightly decreased with an overall EAPC of − 1.30 (− 1.38 – – 1.22). Similar to ASPR, the global age-standardized DALYs rate and age-standardized death rate (ASDR) also declined, with an EAPC of − 1.12(− 2.09 – − 0.14) and − 1.53(− 2.36 – − 0.70) from 1990 to 2019, respectively. Conversely, the number of ACM-related DALYs cases in 2019 was 2,441,108 (95% UI: 2,046,734–2,782,542), with an increase of 38.8%(2.8–59.9) over the past 30 years, and the number of ACM-related deaths in 2019 was 71,723 (95% UI: 60,167–81,995), with an increase of 33.1% (0.5– 51.9) compared with 1990. A significant variation in the burden of ACM was observed between different regions and countries. Although the ASPR, age-standardized DALYs rate and ASDR slightly decreased from 1990 to 2019, the absolute number of prevalent cases, DALYs cases and deaths significantly increased. This showed that the burden of ACM remains an important global public health concern. Public health policy and decision-makers should develop and implement more effective strategies specific to geographical location to combat and reduce the burden of ACM in the future.
