Temporal Trends in Substance Use and Cardiovascular Disease–Related Mortality in the United States

BACKGROUND: There are limited data on substance use (SU) and cardiovascular disease (CVD)-related mortality trends in the United States. We aimed to evaluate SU+CVD-related deaths in the United States using the Centers for Disease Control and Prevention Wide-Ranging, Online Data for Epidemiologic Research database. METHODS AND RESULTS: The Multiple Cause-of-Death Public Use record death certificates were used to identify deaths related to both SU and CVD. Crude, age-adjusted mortality rates, annual percent change, and average annual percent changes with a 95% CI were analyzed. Between 1999 and 2019, there were 636 572 SU+CVD-related deaths (75.6% men, 70.6% non-Hispanic White individuals, 65% related to alcohol). Age-adjusted mortality rates per 100 000 population were pronounced in men (22.5 95% CI, 22.6-22.6), American Indian or Alaska Native individuals (37.7 95% CI, 37.0-38.4), nonmetropolitan/rural areas (15.2 95% CI, 15.1-15.3), and alcohol-related death (9.09 95% CI, 9.07 to 9.12). The overall SU+CVD-related age-adjusted mortality rates increased from 9.9 (95% CI, 9.8-10.1) in 1999 to 21.4 (95% CI, 21.2-21.6) in 2019 with an average annual percent change of 4.0 (95% CI, 3.7-4.3). Increases in SU+CVD-related average annual percent change were noted across all subgroups and were pronounced among women (4.8% 95% CI, 4.5-5.1), American Indian or Alaska Native individuals, younger individuals, nonmetropolitan areas, and cannabis and psychostimulant users. CONCLUSIONS: There was a prominent increase in SU+CVD-related mortality in the United States between 1999 and 2019. Women, non-Hispanic American Indian or Alaska Native individuals, younger individuals, nonmetropolitan area residents, and users of cannabis and psychostimulants had pronounced increases in SU+CVD mortality.
