Background Studies have demonstrated neighborhood structural inequities are associated with cardiovascular outcomes among breast cancer survivors. We investigated the associations between bias in mortgage lending practices (contemporary redlining and racial lending bias) and cardiovascular outcomes in women with breast cancer. Methods Using the SEER (Surveillance, Epidemiology, and End Results)–Medicare database, we identified 51 007 Black and White women diagnosed with breast cancer between 2010 and 2014 with follow‐up through 2020. We used Home Mortgage Disclosure Act data to calculate census‐tract contemporary redlining index and racial lending bias index, and assessed indices continuously and categorically (low, moderate, or high). We used Cox proportional hazards regression to estimate multivariable‐adjusted, cause‐specific hazard ratios (HRs) for major adverse cardiovascular events, ischemic heart disease, heart failure, stroke, and cardiovascular death. Results In the overall population, a 10%‐unit increase in redlining was associated with increased risk of major adverse cardiovascular events (HR, 1.04 [95% CI, 1.02–1.06]). Among Black women, those in high redlining neighborhoods had an increased heart failure risk compared with those in low redlining neighborhoods (HR, 1.22 [95% CI, 1.05–1.41]). Similarly, White women in high redlining neighborhoods had an increased risk of ischemic heart disease (HR, 1.23 [95% CI, 1.15–1.30]) and stroke (HR, 1.09 [95% CI, 1.03–1.16]). Black women in high racial lending bias neighborhoods had reduced cardiovascular mortality risk compared with those in low racial lending bias neighborhoods (HR, 0.69 [95% CI, 0.54–0.90]). Conclusions We identified associations between contemporary redlining and cardiovascular outcomes among breast cancer survivors. High racial lending bias was associated with reduced cardiovascular mortality risk among Black women. Bias in mortgage lending practices may serve as a structural driver of cardiovascular disparities.

BACKGROUND: For reasons not fully understood, Black adults experience more socioeconomic disadvantages (SED) than their White counterparts, as well as earlier onset and greater mortality from heart failure (HF). The John Henryism hypothesis predicts that repeated high-effort coping, that is, John Henryism (JH), with socioeconomic adversity can accelerate cardiovascular aging, thus increasing the risk for HF. METHODS: The analysis sample consisted of participants from the JHS (Jackson Heart Study), a cohort of Black adults from the Jackson, Mississippi Metropolitan area. The analysis sample included participants with no cardiovascular disease at baseline (2000–2004) with complete SED and JH scores. Indicators of SED included low household income, low educational attainment, and low maternal educational attainment scores. JH scores (0–36) were categorized as low (<28), moderate (29–32), and high (>32). Effect moderation of JH in the SED and incident HF association was assessed using interaction terms and stratification. Proportional hazards regression determined the hazard ratio and 95% CI, and models adjusted for age, sex, and established lifestyle risk factors. RESULTS: Among 1704 participants (mean age: 52.15 years, 64.3% female), 100 HF events occurred by 2016 (mean follow-up, 10 years). A statistically significant interaction between income and JH was observed for incident HF ( P =0.04). For every 1-unit increase in income disadvantage score, the risk of HF increased 2-fold among those with high JH (hazard ratio, 2.00 [95% CI, 1.39–2.86]) after full adjustment. Among participants with low JH, the corresponding unadjusted association was hazard ratio, 1.40 [95% CI, 1.04–1.90], but this association attenuated after adjusting for age and sex (hazard ratio, 1.19 [95% CI, 0.87–1.63]). CONCLUSIONS: The association between income disadvantage and HF differed by JH level. Because SED and high JH tend to co-occur, both should be considered in future research aiming to decrease the burden of HF in Black Americans.

The COVID-19 pandemic caused unprecedented disruption of social networks and negatively impacted social determinants of health (SDoH, e.g., economic stability, mental health, health care access) among African Americans. The FAITH! (Fostering African-American Improvement in Total Health!) Program, an academic-community partnership with African American churches, pivoted to pandemic-related impacts on health behaviors of African Americans. This exploratory, cross-sectional study examined associations between multilevel factors influencing difficulty maintaining a healthy lifestyle during the early pandemic phase, including mental/emotional health and COVID-19 hardships (e.g., job/food/housing insecurity, paying utilities). An online survey was distributed via FAITH!-affiliated churches and social media. Logistic regression (odds ratios [ORs], adjusted for age/gender) and associated 95% confidence intervals [CIs]) examined associations between difficulty maintaining a healthy lifestyle and multilevel factors. Greater than half of respondents reported difficulty maintaining a healthy lifestyle (N = 169, 54% [91/169]). Adjusted odds of having difficulty maintaining a healthy lifestyle were greater for those reporting mental/emotional health issues (high-stress OR 4.0; 95% CI [1.9,8.9], p < .001); occasional symptoms of depression (OR 3.7; 95% CI [01.9,7.7]; p < .001); anger (OR 2.5; 95% CI [1.2,5.4]; p = .044), and anxiety (OR 2.8; 95% CI [1.4,6.0]; p = .008)). COVID-19 hardships of job insecurity (OR 1.4.; 95% CI [0.7, 2,8]; p = .015), difficulty paying rent (OR 4.4; 95% CI [2.1,9.9]; p < .001) or difficulty paying for food/utilities (OR 5.4; 95% CI [2.6,11.7]; p < .001) were associated with difficulty maintaining a healthy lifestyle. Our study revealed the negative impact of mental/emotional health and COVID-19 hardships on maintaining a healthy lifestyle among African Americans. This could inform SDoH-focused lifestyle interventions during future public health crises.

Background Although telehealth cardiac rehabilitation (CR) may improve access, there are concerns about its long‐term effectiveness and impact on equity as compared with in‐person CR. Our objective was to tailor a patient‐centered telehealth CR program for diverse populations. Methods CR patients and caregivers were recruited between January and September 2023 from 4 US academic medical centers. Participants engaged in human‐centered design sessions to iteratively refine a telehealth CR program. Sessions had planned topics, but there was variation across sites to account for site‐specific needs and participant feedback. Sessions were qualitatively analyzed using rapid template analysis with preselected behavioral science constructs and other emergent codes. Results The study included 21 participants (71% aged ≥60 years, 48% women, 62% non‐Hispanic White individuals; 90% CR patients, 10% CR caregivers). Participants thought that telehealth CR could be helpful for personalized support at home and convenience but recognized that technology is not always easy to use. Some expressed concerns about the safety of telehealth CR, especially at the beginning, and desired monitoring through a mobile device or video observation of exercise. Safety protocols and technology training were developed, which addressed concerns about telehealth CR. Opportunities for social support with telehealth CR were also desired. From these findings, an implementation toolkit was developed, including a graphic program description, safety plan, home exercise plan for during and after CR, and scripts for technology training and individual and group telehealth visits. Conclusions A patient‐centered telehealth CR program and implementation toolkit were systematically tailored to address the needs of diverse populations.

Background Cardiac rehabilitation (CR) is a comprehensive secondary cardiovascular disease program with structured lifestyle interventions to reduce morbidity and mortality. The American Heart Association cardiovascular health (CVH) framework measures health‐promoting behaviors and clinical factors, but it has not been rigorously evaluated in the CR setting. Methods This retrospective cohort study analyzed patients attending CR from January 2018 to September 2020. Patients were evaluated at baseline (pre‐CR) and completion (post‐CR) using 3 clinical factors (blood pressure, cholesterol, and hemoglobin A1c) and 4 health behaviors (smoking, body mass index, physical activity, and diet). CVH score was computed as a composite of each Life's Simple 7 component by assigning 0 points for poor, 1 point for intermediate, or 2 points for ideal (range 0–14 points). CVH scores were further categorized as poor (0–6 points), intermediate (7–8 points), and ideal (9–14 points). Missing data in the analysis were accounted for using a multiple imputation procedure. Results Patients (N=937) were aged 64.0±13.4 years old, 34% women, and attended 11±12 CR sessions. Pre‐CR, 97.2% had poor CVH scores, 2.8% had intermediate scores, and none met ideal CVH criteria. Post‐CR, there was a reduction in poor scores across all metrics except for hemoglobin A1c, which increased (40.6%–43.5%). Younger patients showed improvement in hemoglobin A1c, while older patients improved in body mass index and blood pressure. Conclusions Our study demonstrates the efficacy of CR in improving CVH but underscores the need for better blood glucose management. Tailored interventions based on age and sex may further optimize outcomes for CR participants.

BACKGROUND: Mortality due to ischemic heart disease (IHD) has declined in countries with high socioeconomic development. Whether these declines extend to other settings, and whether socioeconomic development influences IHD mortality among men and women differently, is unknown. METHODS: We obtained annual data on sex-specific IHD mortality rates for countries/territories in the GBD study (Global Burden of Disease) from 1980 to 2021. The sociodemographic index (SI), a measure of socioeconomic development, was retrieved for each country/territory. Age-adjusted IHD mortality rates were modeled as a smooth function of sex, year, and SI. RESULTS: From 1980 to 2021, IHD mortality rates did not decrease in low SI settings for men or women. In contrast, mortality rates relative to 1980 declined by >25% in average SI settings (age-adjusted mortality per 100 000, 153–107 for women and 218–161 for men) and >50% in high SI settings (age-adjusted mortality per 100 000, 162–69 for women and 258–114 for men). Comparing the 20th versus 80th percentile of SI in 2021 (corresponding to lower versus higher socioeconomic development), mortality rates were 81% higher for men and 111% higher for women living in socioeconomically deprived settings ( P for difference by sex: 0.01), although absolute differences were larger in men. The association of low SI with higher IHD mortality was especially pronounced for mortality attributable to environmental/occupational risk factors (eg, particulate matter air pollution, lead exposure, and extremes of temperature), with mortality rates being 174% higher among women and 199% higher among men. CONCLUSIONS: Across the past 4 decades, low socioeconomic development was associated with no improvement in IHD mortality rates for men or women, in contrast to the large reductions observed in settings with high socioeconomic development. In contemporary settings, socioeconomic deprivation is associated with larger relative excess mortality in women and larger absolute excess mortality in men.

Background African Americans have a higher prevalence of cardiovascular risk factors, leading to higher cardiovascular disease mortality than White adults. Our culturally tailored mobile health (mHealth) lifestyle intervention ( FAITH! App) has previously demonstrated efficacy in promoting ideal cardiovascular health in African Americans. Methods We conducted a secondary analysis from a cluster randomized controlled trial among African-Americans from 16 churches in Minnesota that compared the FAITH! App to a delayed intervention control group. A subgroup of participants with ≥ 1 diagnosis of overweight/obesity, hyperlipidemia, hypertension, or diabetes was examined. The primary outcome was a change in LS7 score—a measure of cardiovascular health ranging from poor to ideal (range 0–14 points)—at 6-months post-intervention. Results The analysis included 49 participants (intervention group: n = 20; mean age 58.8 years, 75% female; control group: n = 29, mean age 52.5 years, 76% female) with no significant baseline differences in cardiovascular risk factors. Compared to the control group, the intervention group showed a greater increase in LS7 score across all cardiovascular risk factors at 6-months post-intervention, with statistically significant differences among those with overweight/obesity (intervention effect 1.77, p < 0.0001) and 2+ or 3+ cardiovascular risk factors (1.00, p = 0.03; 1.09, p = 0.04). The intervention group demonstrated a higher increase in the percentage of participants with intermediate or ideal LS7 scores than the control group, although these differences were not statistically significant. Conclusions Our culturally tailored mHealth lifestyle intervention was associated with significant increases in LS7 scores among African Americans with preexisting cardiovascular risk factors, suggesting its efficacy in improving cardiovascular health among this population.

BACKGROUND: It is unknown whether predelivery cardiology care is associated with future risk of major adverse cardiovascular events (MACE) in preeclampsia/eclampsia (PrE/E). We sought to determine the cumulative incidence of MACE by race and whether predelivery cardiology care was associated with the hazard of MACE up to 1 year post-delivery for Black and White patients with PrE/E. METHODS: Using Optum’s de-identified Clinformatics Data Mart Database, we identified Black and White patients with PrE/E who had a delivery between 2008 and 2019. MACE was defined as the composite of heart failure, acute myocardial infarction, stroke, and death. Cumulative incidence functions were used to compare the incidence of MACE by race. Regression models were used to assess the hazard of MACE by cardiology care for each race. Separate hazards were calculated for the first 14 days and the remainder of the year. RESULTS: Among 29 336 patients (83.4% White patients, 16.6% Black patients, 99.5% commercially insured, mean age: 30.9 years) with PrE/E, 11.2% received cardiology care (10.9% White patients, 13.0% Black patients). Black patients had higher incidence of MACE than White patients at 1 year post-delivery (2.7% versus 1.4%) with the majority within 14 days of delivery (Black patients: 58.7%; White patients: 67.8%). After adjusting for age and comorbidities, receipt of cardiology care was associated with a lower hazard of MACE for White patients within 14 days after delivery (hazard ratio, 0.31 [95% CI, 0.21–0.46]; P <0.001) but not Black patients (hazard ratio, 1.00 [95% CI, 0.60–1.67]; P =0.999). The effect of the interaction between race and cardiology care was significant in the first 14 days ( P <0.001) but not the remainder of the year ( P =0.56). CONCLUSIONS: Among a well-insured population of patients with PrE/E, Black patients had a higher cumulative incidence of MACE up to a year post-delivery. Cardiology care was associated with a lower hazard of MACE only for White patients during the first 14 days after delivery.
