ABSTRACT
Background: Cardiovascular diseases contribute to considerable morbidity and mortality in the USA. We sought to establish regional disparities across the nation contributing to cardiovascular disease (CVD) among non-elective young adult hospitalizations. Methods: The National Inpatient Sample (2019) was utilized to identify the incidence of non-elective hospitalizations among young adults (18-44 yrs) and analyze the burden of CVD risk factors and outcomes (MACCE; all-cause mortality, AMI, cardiac arrest and stroke) in different US regions. Results: A total of 5,833,930 (median age 32 [26-37] years) non-elective admissions were recorded; plurality from the south (39.6%). Most admissions were white (51.4%) and female (65.5%) amid all regions. The burden of CVD risk factors was significantly higher in the South followed by the Mid-west regions. The South had the highest and the Northeast had the lowest rates of MACE (2.9% vs 2.3%) and stroke (1.0% vs 0.8%). The risk of AMI was high for the south and Midwest regions (1.1%). All-cause mortality was highest in South and West regions (0.7%). Multivariate adjusted odds for these cardiovascular events were higher in the West (aOR 1.22; 95%CI 1.12-1.33) followed by South (aOR 1.16; 95%CI 1.07-1.26) regions. Conclusions: This population-based study assessing non-elective admissions in the young revealed a higher burden of CVD risk factors and rate of MACCE in the South compared to other areas of the USA. Regional policies should be tailored to the local CVD risk burden.
