Achieving Equitable Cardiovascular Care for All: ACC Board of Trustees Health Equity Task Force Action Plan.

Advancements in cardiovascular (CV) disease management are notable, yet health inequities prevail, associated with increased morbidity and mortality noted among non-Hispanic African Americans in the United States. The 2002 Institute of Medicine Report revealed ongoing racial and ethnic health care disparities, spearheading a deeper understanding of the social determinants of health and systemic racism to develop strategies for CV health equity (HE). This article outlines the strategic HE approach of the American College of Cardiology, comprising 6 strategic equity domains: workforce pathway inclusivity, health care, data, science, and tools; education and training; membership, partnership, and collaboration; advocacy and policy; and clinical trial diversity. The American College of Cardiology's Health Equity Task Force champions the improvement of patients' lived experiences, population health, and clinician well-being while reducing health care costs-the Quadruple Aim of Health Equity. Thus, we examine multifaceted HE interventions and provide evidence for scalable real-world interventions to promote equitable CV care.

Racial Disparities in Sports Cardiology: A Review.

Importance: Racial disparities in cardiovascular health, including sudden cardiac death (SCD), exist among both the general and athlete populations. Among competitive athletes, disparities in health outcomes potentially influenced by social determinants of health (SDOH) and structural racism remain inadequately understood. This narrative review centers on race in sports cardiology, addressing racial disparities in SCD risk, false-positive cardiac screening rates among athletes, and the prevalence of left ventricular hypertrophy, and encourages a reexamination of race-based practices in sports cardiology, such as the interpretation of screening 12-lead electrocardiogram findings. Observations: Drawing from an array of sources, including epidemiological data and broader medical literature, this narrative review discusses racial disparities in sports cardiology and calls for a paradigm shift in approach that encompasses 3 key principles: race-conscious awareness, clinical inclusivity, and research-driven refinement of clinical practice. These proposed principles call for a shift away from race-based assumptions towards individualized, health-focused care in sports cardiology. This shift would include fostering awareness of sociopolitical constructs, diversifying the medical team workforce, and conducting diverse, evidence-based research to better understand disparities and address inequities in sports cardiology care. Conclusions and Relevance: In sports cardiology, inadequate consideration of the impact of structural racism and SDOH on racial disparities in health outcomes among athletes has resulted in potential biases in current normative standards and in the clinical approach to the cardiovascular care of athletes. An evidence-based approach to successfully address disparities requires pivoting from outdated race-based practices to a race-conscious framework to better understand and improve health care outcomes for diverse athletic populations.

ECG findings in professional rugby players using international screening recommendations.

Background: While World Rugby guidelines do not mandate the inclusion of an electrocardiogram (ECG) for all players, this is required for entry into international rugby competitions. We, therefore, sought to describe sport-specific normative ECG values and evaluate the performance of contemporary athlete ECG guidelines in male and female professional rugby players. Methods: We retrospectively analysed professional rugby players' ECGs (n=356, male 79%) obtained during preparticipation screening (2010-2022), comparing by sex and playing position (forwards vs backs). ECGs were categorised as normal 'training-related', borderline and abnormal findings, as defined by the 2017 International Recommendations. Results: 84% of players had one or more normal, 'training-related' findings, with males having a higher prevalence than females (91% vs 60%, p<0.001). Most ECG findings did not vary by position. No female player had borderline or abnormal ECG findings. Borderline findings were present in 3% (n=12/356) of players. Abnormal findings were present in 2% (n=7/356) of players. Overall, 2.2% of ECGs were 'positive' (n=8/356, including n=1 ECG with two borderline findings). Conclusions: The application of contemporary ECG interpretation criteria resulted in a low positivity rate isolated to male players. These results help inform the logistic feasibility of ECG-inclusive screening, which is already required to enter major tournaments.

Consumer Wearable Health and Fitness Technology in Cardiovascular Medicine: JACC State-of-the-Art Review.

The use of consumer wearable devices (CWDs) to track health and fitness has rapidly expanded over recent years because of advances in technology. The general population now has the capability to continuously track vital signs, exercise output, and advanced health metrics. Although understanding of basic health metrics may be intuitive (eg, peak heart rate), more complex metrics are derived from proprietary algorithms, differ among device manufacturers, and may not historically be common in clinical practice (eg, peak V˙O2, exercise recovery scores). With the massive expansion of data collected at an individual patient level, careful interpretation is imperative. In this review, we critically analyze common health metrics provided by CWDs, describe common pitfalls in CWD interpretation, provide recommendations for the interpretation of abnormal results, present the utility of CWDs in exercise prescription, examine health disparities and inequities in CWD use and development, and present future directions for research and development.

Coronavirus, Refugees, and Government Policy: The State of U.S. Refugee Resettlement during the Coronavirus Pandemic.

The novel coronavirus pandemic poses unique challenges to forcibly displaced populations around the world. Months into the pandemic, countries are still scrambling to enact policies that mitigate the outbreak and minimize the strain on their health-care infrastructures and economies. The United Nations High Commissioner for Refugees continues to work with member states to provide guidance and assistance to those populations protected under their mandate. However, there is great concern regarding the ability to appropriately provide for displaced populations, as they tend to be hosted in areas that lack access to health care and proper hygiene materials. The situation has been exacerbated by the temporary suspension of refugee resettlement across the globe. In the United States, the Trump Administration has responded to the crisis by further eroding refugee and asylum resettlement programs and failing to properly protect the asylum seekers currently being detained. At the local level, resettled refugees and asylees have responded to the unique challenges posed by coronavirus by using their skillsets to provide assistance and services to community members in need. The coronavirus, and the Trump Administration's response, are likely to have long-term negative impacts on refugee resettlement and asylum programs.

Relation of Living in a "Food Desert" to Recurrent Hospitalizations in Patients With Heart Failure.

Food deserts (FD), low-income areas with low access to healthful foods, are associated with higher burden of cardiovascular risk factors. Few studies have examined the impact of FD on clinical outcomes in heart failure (HF). FD status was assessed in 457 HF patients (mean age 55.9 ± 12.5 years; 50.3% Black) using the Food Desert Research Atlas. The Andersen-Gill extension of Cox model was used to examine the association of living in a FD with risk of repeat hospitalization (all-cause and HF-specific). Patients living in a FD were younger (p = 0.01), more likely to be Black (p <0.0001), less educated (p = 0.003), and less likely to have commercial insurance (p = 0.003). During a median follow-up of 827 (506, 1,379) days, death occurred in 60 (13.1%) subjects, and hospitalizations occurred in 262 (57.3%) subjects. There was no difference in the risk of death based on FD status. The overall frequency of all-cause (94.1 vs 63.6 per 100 patient-years) and HF-specific (59.6 vs 30.5 per 100 patient-years) hospitalizations was higher in subjects who lived in a FD. After adjustment for covariates, living in a FD was associated with an increased risk of repeat all-cause (hazard ratio 1.39, 95% confidence interval 1.19 to 1.63; p = 0.03) and HF-specific (hazard ratio 1.30, 95% confidence interval 1.02 to 1.65; p = 0.03) hospitalizations. In conclusion, patients living in a FD have a higher risk of repeat all-cause and HF-specific hospitalization.

Progenitor Cells and Clinical Outcomes in Patients With Acute Coronary Syndromes.

RATIONALE: Circulating progenitor cells (CPCs) mobilize in response to ischemic injury, but their predictive value remains unknown in acute coronary syndrome (ACS). OBJECTIVE: We aimed to investigate the number of CPCs in ACS compared with those with stable coronary artery disease (CAD), relationship between bone marrow PCs and CPCs, and whether CPC counts predict mortality in patients with ACS. METHODS AND RESULTS: In 2028 patients, 346 had unstable angina, 183 had an acute myocardial infarction (AMI), and the remaining 1499 patients had stable CAD. Patients with ACS were followed for the primary end point of all-cause death. CPCs were enumerated by flow cytometry as mononuclear cells expressing a combination of CD34+, CD133+, vascular endothelial growth factor receptor 2+, or chemokine (C-X-C motif) receptor 4+. CPC counts were higher in subjects with AMI compared those with stable CAD even after adjustment for age, sex, race, body mass index, renal function, hypertension, diabetes mellitus, hyperlipidemia, and smoking; CD34+, CD34+/CD133+, CD34+/CXCR4+, and CD34+/VEGFR2+ CPC counts were 19%, 25%, 28%, and 142% higher in those with AMI, respectively, compared with stable CAD. There were strong correlations between the concentrations of CPCs and the PC counts in bone marrow aspirates in 20 patients with AMI. During a 2 (interquartile range, 1.31-2.86)-year follow-up period of 529 patients with ACS, 12.4% died. In Cox regression models adjusted for age, sex, body mass index, heart failure history, estimated glomerular filtration rate, and AMI, subjects with low CD34+ cell counts had a 2.46-fold (95% confidence interval, 1.18-5.13) increase in all-cause mortality, P=0.01. CD34+/CD133+ and CD34+/CXCR4+, but not CD34+/VEGFR2+ PC counts, had similar associations with mortality. Results were validated in a separate cohort of 238 patients with ACS. CONCLUSIONS: CPC levels are significantly higher in patients after an AMI compared with those with stable CAD and reflect bone marrow PC content. Among patients with ACS, a lower number of hematopoietic-enriched CPCs are associated with a higher mortality.

Racial differences in the development of de-novo donor-specific antibodies and treated antibody-mediated rejection after heart transplantation.

BACKGROUND: Despite improvements in outcomes after heart transplantation, black recipients have worse survival compared with non-black recipients. The source of such disparate outcomes remains largely unknown. We hypothesize that a propensity to generate de-novo donor-specific antibodies (dnDSA) and subsequent antibody-mediated rejection (AMR) may account for racial differences in sub-optimal outcomes after heart transplant. In this study we aimed to determine the role of dnDSA and AMR in racial disparities in post-transplant outcomes. METHODS: This study was a single-center, retrospective analysis of 137 heart transplant recipients (81% male, 48% black) discharged from Emory University Hospital. Patients were classified as black vs non-black for the purpose of our analysis. Kaplan-Meier and Cox regression analyses were used to evaluate the association between race and selected outcomes. The primary outcome was the development of dnDSA. Secondary outcomes included treated AMR and a composite of all-cause graft dysfunction or death. RESULTS: After 3.7 years of follow-up, 39 (28.5%) patients developed dnDSA and 19 (13.8%) were treated for AMR. In multivariable models, black race was associated with a higher risk of developing dnDSA (hazard ratio [HR] 3.65, 95% confidence interval [CI] 1.54 to 8.65, p = 0.003) and a higher risk of treated AMR (HR 4.86, 95% CI 1.26 to 18.72, p = 0.021) compared with non-black race. Black race was also associated with a higher risk of all-cause graft dysfunction or death in univariate analyses (HR 2.10, 95% CI 1.02 to 4.30, p = 0.044). However, in a multivariable model incorporating dnDSA, black race was no longer a significant risk factor. Only dnDSA development was significantly associated with all-cause graft dysfunction or death (HR 4.85, 95% CI 1.89 to 12.44, p = 0.001). CONCLUSION: Black transplant recipients are at higher risk for the development of dnDSA and treated AMR, which may account for racial disparities in outcomes after heart transplantation.

How do we die?

Within the next two decades, the elderly population in the United States will reach its zenith, comprising 73 million individuals, 20 percent of the nation, the baby boomers' final surge. The process of their dying may become contentious. Should policymakers and bioethicists be satisfied with our current approach to dying, or should they begin now to reconceptualize it? We distill end-of-life discussions in the bioethics literature and popular press, paying particular attention to physician-assisted suicide and its uptake where legal. Evidence so far indicates that few of the dying opt for this alternative, suggesting that its role in assuring "death with dignity" cannot be, as may have been hoped, a leading one. The end-of-life literature on the whole lends credence to the fear that most of the dying, along with their families and physicians, will muddle through a morass of uncoordinated options, with futile medical intervention the most prominent outcome ­ despite more palliative strategies, such as home hospice care, being favorably described. We found no reason to recommend persistence in our current approach to dying and found good reason to urge early, conscientious, and thoroughgoing reconceptualization in policy and practice as well as in theory.
