Abstract 15263: Trends and Clustering in Cardiovascular Health Metrics by Race and Ethnicity Among US Adults, 2011-2020

Circulation, Volume 146, Issue Suppl_1, Page A15263-A15263, November 8, 2022. Introduction:Nationally representative data evaluating recent trends and clustering in cardiovascular health metrics by race and ethnicity are sparse.Methods:We evaluated 10-year trends and clustering in cardiovascular health metrics in 10,300 individuals who attended the morning fasting examination, using data from the National Health and Nutrition Examination Surveys (NHANES) from 2011 to 2020. We assessed the time trends of the mean score of the 7 cardiovascular health metrics by race and ethnicity. Then we ranked the top 10 mutually exclusive phenotypes of the 7 cardiovascular health metrics for each race and ethnicity.Results:Among participants, the mean age was 48.3 (SD, 4.2) years; 52% were female; 6.3%, 71.3%, 12.7%, and 9.7% were Asian, White, Black, and Hispanic. From 2011 to 2020, the total cardiovascular health score decreased significantly for Asian individuals (P=0.005) but did not change significantly for Black, Hispanic, and White individuals (P >0.05 for all). The mean scores for individual cardiovascular health metrics did not change by racial/ethnic subgroups, except for a decrease in mean body mass index (BMI) score in Asian individuals, an increase in mean total cholesterol score in Black individuals, a decrease in mean fasting glucose score in Asian, Hispanic, and White individuals. Among all the individuals, healthy diet and the combination of healthy diet and physical activity were the two most prevalent phenotypes, followed by several different combinations of physical activity, BMI, healthy diet, and smoking.Conclusions:Temporal trends suggest an overall unchanged mean total cardiovascular health score for Black, Hispanic, and White individuals and a decreased score for Asian individuals. There were persistent racial/ethnic disparities in the individual cardiovascular health metrics and phenotypes. Across all racial/ethnic subgroups, large opportunities exist for improvements.

Abstract 15756: The Beneficial Impact of Primary Care Providers’ Supply on the Cardiovascular Mortality Rates in the United States: A Nationwide Population Analysis 2011-2019

Circulation, Volume 146, Issue Suppl_1, Page A15756-A15756, November 8, 2022. Introduction:United States is facing an increasing shortage of primary care physicians (PCP) and health care demands. However, data on the relationship between PCP availability and burden of cardiovascular mortality (CVM) and related disparities, is limited.Hypothesis:Herein, we evaluate the nationwide impact of county PCP levels on CVM in overall and within disparate populations stratified by age, sex, and race/ethnic subgroups.Methods:PCP is calculated as the ratio of PCPs to the population, using data from National Center for Health statistics. Age-adjusted CVM rates (ACVM) between 2011 to 2019, were obtained using CDC database. Behavioral Risk Factor Surveillance was utilized to acquire county characteristics and confounders. Poisson linear mixed model was employed.Results:Of 3143 U.S. counties, 2900 counties (62% white; 51% female; 14% aged ≥65) had data available on ACVM and PCP.In a multivariate model adjusted for demographics, CV risk, socioeconomic, and environmental factors, higher PCP levels significantly associated with lower ACVM (Standardized IRR: 0.979; 95% CI: 0.972 to 0.986), which translates to 4.8 fewer CV deaths each year (AYD). This effect was relatively higher in middle-aged [45-64] (IRR: 0.967) versus elderly [≥65] (IRR: 0.980), males (IRR: 0.981) versus females (IRR: 0.972), and within Whites (IRR: 0.976). Notably, the relative impact of PCP was greatest in [45-64] Whites (IRR: 0.963), while the absolute impact was highest amongst ≥65 males with 36 fewer CV deaths each year. (Figure).Conclusions:Higher PCP supply is robustly associated with lower ACVM, and that beneficial effect is most evident amongst both age and sex subgroups as well as non-Hispanic whites. Moreover, this association is significantly independent of potential confounders that have a plausible association with CVM. Therefore, population-level strategies to promote primary care access, are imperative for reducing the burden of CVM and promoting health equity.

Abstract 14682: Gender Disparities in Hypertrophic Cardiomyopathy After Septal Myectomy – Insights From the National Inpatient Sample 2011-2019

Circulation, Volume 146, Issue Suppl_1, Page A14682-A14682, November 8, 2022. Introduction:Data suggests that women with hypertrophic cardiomyopathy (HCM) have worse clinical outcomes than men. However, data from large multi-center studies on gender differences in patients who undergo septal myectomy (SM) is scarce.Methods:The National Inpatient Database was queried from 2011- 2019 for relevant ICD-9 and -10 diagnostic and procedural codes. We compared baseline characteristics and in-hospital outcomes of patients with HCM who underwent SM stratified according to male vs. female gender. A p-value
