Geographic and racial variability in kidney, cardiovascular and safety outcomes with canagliflozin: A secondary analysis of the CREDENCE randomized trial. Diabetes Obes Metab 2024; 26:3530-3540. [PMID: 38895796 DOI: 10.1111/dom.15685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Revised: 04/26/2024] [Accepted: 05/04/2024] [Indexed: 06/21/2024]
Abstract
AIM To explore the effect of canagliflozin on kidney and cardiovascular events and safety outcomes in individuals with type 2 diabetes and chronic kidney disease across geographic regions and racial groups. MATERIALS AND METHODS A stratified Cox proportional hazards model was used to assess efficacy and safety outcomes by geographic region and racial group. The primary composite outcome was a composite of end-stage kidney disease (ESKD), doubling of the serum creatinine (SCr) level, or death from kidney or cardiovascular causes. Secondary outcomes included: (i) cardiovascular death or heart failure (HF) hospitalization; (ii) cardiovascular death, myocardial infarction (MI) or stroke; (iii) HF hospitalization; (iv) doubling of the SCr level, ESKD or kidney death; (v) cardiovascular death; (vi) all-cause death; and (vii) cardiovascular death, MI, stroke, or hospitalization for HF or for unstable angina. RESULTS The 4401 patients were divided into six geographic region subgroups: North America (n = 1182, 27%), Central and South America (n = 941, 21%), Eastern Europe (n = 947, 21%), Western Europe (n = 421, 10%), Asia (n = 749, 17%) and Other (n = 161, 4%). The analyses included four racial groups: White (n = 2931, 67%), Black or African American (n = 224, 5%), Asian (n = 877, 20%) and Other (n = 369, 8%). Canagliflozin reduced the relative risk of the primary composite outcome in the overall trial by 30% (hazard ratio 0.70, 95% confidence interval 0.59-0.82; P = 0.00001). Across geographic regions and racial groups, canagliflozin consistently reduced the primary composite endpoint without evidence of heterogeneity (interaction P values of 0.39 and 0.91, respectively) or significant safety outcome differences. CONCLUSIONS Canagliflozin reduces the risk of kidney and cardiovascular events similarly across geographic regions and racial groups.

Abstract
Heart failure is a commonly encountered clinical syndrome arising from a range of etiologic cardiovascular diseases and manifests in a phenotypic spectrum of varying degrees of systolic and diastolic ventricular dysfunction. Those affected by this life-limiting illness are subject to an array of burdensome symptoms, poor quality of life, prognostic uncertainty, and a relatively onerous and increasingly complex treatment regimen. This condition occurs in epidemic proportions worldwide, and given the demographic trend in societal ageing, the prevalence of heart failure is only likely to increase. The marked upturn in international migration has generated other demographic changes in recent years, and it is evident that we are living and working in ever more ethnically and culturally diverse communities. Professionals treating those with heart failure are now dealing with a much more culturally disparate clinical cohort. Given that the heart failure disease trajectory is unique to each individual, these clinicians need to ensure that their proposed treatment options and responses to the inevitable crises intrinsic to this condition are in keeping with the culturally determined values, preferences, and worldviews of these patients and their families. In this narrative review, we describe the importance of cultural awareness across a range of themes relevant to heart failure management and emphasize the centrality of cultural competence as the basis of appropriate care provision.

Racial and Ethnic Disparities in Patients Who Underwent Leadless Pacemaker Implantation. Am J Cardiol 2023; 208:153-155. [PMID: 37839459 DOI: 10.1016/j.amjcard.2023.09.072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 09/18/2023] [Indexed: 10/17/2023]
Abstract
Evidence regarding racial disparities in leadless pacemaker (LP) utilization and outcomes is limited. We aimed to explore ethnicity-based disparities in LP utilization and clinical outcomes of patients who underwent LP implantation. All consecutive patients who underwent LP between January 2019 and January 2023 at our institution were included. Charts were reviewed for baseline characteristics and clinical outcomes. The primary outcomes were procedure-related complications, cardiac rehospitalization, worsening heart failure (HF) or HF hospitalization, and all-cause mortality. All statistical analyses were performed using SPSS Statistics 22 (IBM Corp., Armonk, NY). The p <0.05 was considered statistically significant. A total of 196 adult patients underwent LP implantation during the study period (48% Caucasians, 36.2% Hispanic, 8.2% Asians, and 7.7% African-American). The groups were balanced with respect to baseline demographics, clinical characteristics, and procedure-related complications. During the median follow-up of 104 days (interquartile range 24 to 382), no statistically significant differences were observed in worsening HF or HF hospitalization or all-cause mortality among the ethnic groups. After multivariable logistic regression, Asian individuals had higher odds of cardiac readmissions (odds ratio 4.1, 95% confidence interval 1.4 to 12.3, p = 0.01). Patients from racial and ethnic minorities face significant inequities in arrhythmia care, including patients who have undergone LP implantation. Awareness and a system-based approach (understanding cultural preferences, effective application of evidence-based guidelines, and population-based policies) are crucial to lessen disparities in health care among minorities.

Abstract
PURPOSE OF REVIEW To discuss the prevailing racial and ethnic disparities in heart failure (HF) care by identifying barriers to equitable care and proposing solutions for achieving equitable outcomes. RECENT FINDINGS Throughout the entire spectrum of HF care, from prevention to implementation of guideline-directed medical therapy and advanced interventions, racial and ethnic disparities exist. Factors such as differential distribution of risk factors, poor access to care, inadequate representation in clinical trials, and discrimination from healthcare clinicians, among others, contribute to these disparities. Recent data suggests that despite improvements, disparities prevail in several aspects of HF care, hindering our progress towards equity in HF care. This review highlights the urgent need to address racial and ethnic disparities in HF care, emphasizing the importance of a multifaceted approach involving policy changes, quality improvement strategies, targeted interventions, and intentional community engagement. Our proposed framework was derived from existing research and emphasizes integrating equity into routine quality improvement efforts, tailoring interventions to specific populations, and advocating for policy transformation. By acknowledging these disparities, implementing evidence-based strategies, and fostering collaborative efforts, the HF community can strive to reduce disparities and achieve equity in HF care.

Abstract
Minoritized racial and ethnic groups have the highest incidence, prevalence, and hospitalization rate for heart failure. Despite improvement in medical therapies and overall survival, the morbidity and mortality of these groups remain elevated. The reasons for this disparity are multifactorial, including social determinant of health (SDOH) such as access to care, bias, and structural racism. These same factors contributed to higher rates of COVID-19 infection among minoritized racial and ethnic groups. In this review, we aim to explore the lessons learned from the COVID-19 pandemic and its interconnection between heart failure and SDOH. The pandemic presents a window of opportunity for achieving greater equity in the health care of all vulnerable populations.

Abstract
Racial, ethnic, and gender disparities are present in the diagnosis and management of valvular heart disease. The prevalence of valvular heart disease varies by race, ethnicity, and gender, but diagnostic evaluations are not equitable across the groups, which makes the true prevalence less clear. The delivery of evidence-based treatments for valvular heart disease is not equitable. This article focuses on the epidemiology of valvular heart diseases associated with heart failure and the related disparities in treatment, with a focus on how to improve delivery of nonpharmacological and pharmacological treatments.

Abstract
AIMS To date, potential differences in outcomes for immigrants and non-immigrants with a cardiac resynchronization therapy (CRT), in a European setting, remain underutilized and unknown. Hence, we examined the efficacy of CRT measured by heart failure (HF)-related hospitalizations and all-cause mortality among immigrants and non-immigrants. METHODS AND RESULTS All immigrants and non-immigrants who underwent first-time CRT implantation in Denmark (2000-2017) were identified from nationwide registries and followed for up to 5 years. Differences in HF related hospitalizations and all-cause mortality were evaluated by Cox regression analyses. From 2000 to 2017, 369 of 10 741 (3.4%) immigrants compared with 7855 of 223 509 (3.5%) non-immigrants with a HF diagnosis underwent CRT implantation. The origins of the immigrants were Europe (61.2%), Middle East (20.1%), Asia-Pacific (11.9%), Africa (3.5%), and America (3.3%). We found similar high uptake of HF guideline-directed pharmacotherapy before and after CRT and a consistent reduction in HF-related hospitalizations the year before vs. the year after CRT (61% vs. 39% for immigrants and 57% vs. 35% for non-immigrants). No overall difference in 5-year mortality among immigrants and non-immigrants was seen after CRT [24.1% and 25.8%, respectively, P-value = 0.50, hazard ratio (HR) = 1.2, 95% confidence interval (CI): 0.8-1.7]. However, immigrants of Middle Eastern origin had a higher mortality rate (HR = 2.2, 95% CI: 1.2-4.1) compared with non-immigrants. Cardiovascular causes were responsible for the majority of deaths irrespective of immigration status (56.7% and 63.9%, respectively). CONCLUSION No overall differences in efficacy of CRT in improving outcomes between immigrants and non-immigrants were identified. Although numbers were low, a higher mortality rate among immigrants of Middle Eastern origin was identified compared with non-immigrants.

Abstract
In cardiology, patients' cultural beliefs, linguistic differences, lack of knowledge, and socioeconomic status can create barriers to choosing device treatment. To address this issue, we conducted a thorough literature review using online databases such as PubMed, Google Scholar, and Texas Tech University Health Sciences Center's research portal. Our review found that cultural, religious, and linguistic barriers can contribute to patients' apprehension and reservations about device placement. These barriers can also impact patients' adherence to treatment and clinical outcomes. Patients from lower socioeconomic backgrounds may have difficulty accessing and affording device-based treatments. Additionally, fear and inadequate understanding of surgical procedures can deter patients from accepting device treatment in cardiology. To overcome these cultural barriers, healthcare providers must raise awareness about the benefits of device treatment and provide better training to overcome these challenges. It is crucial to address the unique needs of patients from different cultural backgrounds and socioeconomic statuses to ensure they receive the care they need.

The primary objective of our study was to evaluate the regional disparities in the use of septal reduction therapies, including septal myectomy and alcohol septal ablation, in patients with HOCM. The secondary objective was to analyze the regional differences in the outcomes in these patients. Patients with HOCM had 87% higher risk-adjusted odds of getting septal myectomy (adjusted odds ratio 1.87, p = 0.03) and 37% lower risk-adjusted odds of getting alcohol septal ablation (adjusted odds ratio 0.63, p = 0.03) in the Midwest than in the Northeast. The in-hospital mortality rate was higher for patients who underwent septal myectomy in the South versus the Northeast on the unadjusted analysis. These differences persisted despite the adjustment for demographic and clinical characteristics. Additional adjustment for hospital volume partially explained these disparities, but the adjustment for both hospital volume and hospital teaching status completely explained these disparities. The risk-adjusted in-hospital mortality in patients who underwent alcohol septal ablation was similar in the South versus other regions. In conclusion, regional disparities may exist in the use of septal myectomy and alcohol septal ablation, and patients with HOCM should be referred to high-volume teaching hospitals for septal myectomy for better outcomes, which may also eliminate the extra burden of hospital mortality in the South.

Abstract
Remote patient monitoring (RPM), within the larger context of telehealth expansion, has been established as an effective and safe means of care for patients with heart failure (HF) during the recent pandemic. Of the demographic groups, female patients and black patients are underenrolled relative to disease distribution in clinical trials and are under-referred for RPM, including remote haemodynamic monitoring, cardiac implantable electronic devices (CIEDs), wearables and telehealth interventions. The sex- and race-based disparities are multifactorial: stringent clinical trial inclusion criteria, distrust of the medical establishment, poor access to healthcare, socioeconomic inequities, and lack of diversity in clinical trial leadership. Notwithstanding addressing the above factors, RPM has the unique potential to reduce disparities through a combination of implicit bias mitigation and earlier detection and intervention for HF disease progression in disadvantaged groups. This review describes the uptake of remote haemodynamic monitoring, CIEDs and telehealth in female patients and black patients with HF, and discusses aetiologies that may contribute to inequities and strategies to promote health equity.

Abstract
The objectives of this retrospective study include identifying the utilization trend of mechanical circulatory devices (MCD) such as Intra-Aortic Balloon Pump (IABP), Impella and Extracorporeal Membrane Oxygenation (ECMO) in admissions with cardiac arrest, determining whether racial or gender disparities exist in their usage, and discerning if their use is associated with a reduction in mortality. By leveraging the National Inpatient Sample, we identified 229,180 weighted adult cardiac arrest admissions between October 1, 2015 and December 31, 2018. MCD were used in 6005 admissions (2.6%). IABP had the highest utilization, representing 77.8% of all MCDs, followed by Impella at 24.8%. The utilization of IABP decreased from 90.6% to 71.6%, while the use of Impella increased from 13.5% to 29.8% in this study period; both trends were statistically significant. MCD use was found to be lower in women compared to men (1.4% vs 3.6, P < 0.001) and in the Black population compared to White (1.5% vs 2.8%, P < 0.001). There was no difference in MCD utilization between Hispanic and the White cohorts. In-hospital mortality was lower in admissions associated with MCD (31.4% vs 45.9%, P < 0.001). ECMO was associated with the lowest mortality rate at 14.3%, followed by IABP at 28.1%. The use of Impella and combination therapy were not associated with a significant decrease in mortality. In conclusion, MCD use may decrease mortality in cardiac arrest, however their utilization appears to be lower in African Americans and in women.

Abstract
Health disparities in heart failure (HF) show that Black patients face greater ED utilization and worse clinical outcomes. Transitional care post-HF hospitalization, such as 7-day early follow-up visits, may prevent ED returns. We examine whether early follow-up is associated with lower ED returns visits within 30 days and whether Black race is associated with receiving early follow-up after HF hospitalization. This was a retrospective cohort analysis of all Black and White adult patients at 13 hospitals in Michigan hospitalized for HF from October 1, 2017, to September 30, 2020. Adjusted risk ratios (aRR) were estimated from multivariable logistic regressions. The analytic sample comprised 6,493 patients (mean age = 71 years (SD 15), 50% female, 37% Black, 9% Medicaid). Ten percent had an ED return within 30 days and almost half (43%) of patients had 7-day early follow-up. Patients with early follow-up had lower risk of ED returns (aRR 0.85 [95%CI, 0.71-0.98]). Regarding rates of early follow-up, there was no overall adjusted association with Black race, but the following variables were related to lower follow-up: Medicaid insurance (aRR 0.90 [95%CI, 0.80-1.00]), dialysis (aRR 0.86 [95%CI, 0.77-0.96]), depression (aRR 0.92 [95%CI, 0.86-0.98]), and discharged with opioids (aRR 0.94 [95%CI, 0.88-1.00]). When considering a hospital-level interaction, three of the 13 sites with the lowest percentage of Black patients had lower rates of early follow-up in Black patients (ranging from 15% to 55% reduced likelihood). Early follow-up visits were associated with a lower likelihood of ED returns for HF patients. Despite this potentially protective association, certain patient factors were associated with being less likely to receive scheduled follow-up visits. Hospitals with lower percentages of Black patients had lower rates of early follow-up for Black patients. Together, these may represent missed opportunities to intervene in high-risk groups to prevent ED returns in patients with HF.

Abstract
Background Descriptions of do not attempt resuscitation (DNAR) orders in heart failure (HF) are limited. We describe use of DNAR orders in HF hospitalizations relative to other common conditions, focusing on race. Methods and Results This was a retrospective study of all adult hospitalizations for HF, acute myocardial infarction (AMI), chronic obstructive pulmonary disease (COPD), and pneumonia from 2010 to 2016 using the California State Inpatient Dataset. Using a hierarchical multivariable logistic regression model with random effects for the hospital, we identified factors associated with DNAR orders for each condition. For racial variation, hospitals were divided into quintiles based on proportion of Black patients cared for. Our cohort comprised 399 816 HF, 190 802 AMI, 192 640 COPD, and 269 262 pneumonia hospitalizations. DNAR orders were most prevalent in HF (11.9%), followed by pneumonia (11.1%), COPD (7.9%), and AMI (7.1%). Prevalence of DNAR orders did not change from 2010 to 2016 for each condition. For all conditions, DNAR orders were more common in elderly people, women, and White people with significant site-level variation across 472 hospitals. For HF and COPD, hospitalizations at sites that cared for a higher proportion of Black patients were less likely associated with DNAR orders. For AMI and pneumonia, conditions such as dementia and malignancy were strongly associated with DNAR orders. Conclusions DNAR orders were present in 12% of HF hospitalizations, similar to pneumonia but higher than AMI and COPD. For HF, we noted significant variability across sites when stratified by proportion of Black patients cared for, suggesting geographic and racial differences in end-of-life care.

Abstract
Background Black and Hispanic patients are less likely to receive cardiac resynchronization therapy (CRT) than White patients. Medicaid expansion has been associated with increased access to cardiovascular care among racial and ethnic groups with higher prevalence of underinsurance. It is unknown whether the Medicaid expansion was associated with increased receipt of CRT by race and ethnicity. Methods and Results Using Healthcare Cost and Utilization Project Data State Inpatient Databases from 19 states and Washington, DC, we analyzed 1061 patients from early-adopter states (Medicaid expansion by January 2014) and 745 patients from nonadopter states (no implementation 2013-2014). Estimates of change in census-adjusted rates of CRT with or without defibrillator by race and ethnicity and Medicaid adopter status 1 year before and after January 2014 were conducted using a quasi-Poisson regression model. Following the Medicaid expansion, the rate of CRT did not significantly change among Black individuals from early-adopter states (1.07 [95% CI, 0.78-1.48]) or nonadopter states (0.79 [95% CI, 0.57-1.09]). There were no significant changes in rates of CRT among Hispanic individuals from early-adopter states (0.99 [95% CI, 0.70-1.38]) or nonadopter states (1.01 [95% CI, 0.65-1.57]). There was a 34% increase in CRT rates among White individuals from early-adopter states (1.34 [95% CI, 1.05-1.70]), and no significant change among White individuals from nonadopter states (0.77 [95% CI, 0.59-1.02]). The change in CRT rates among White individuals was associated with the timing of the Medicaid implementation (P=0.003). Conclusions Among states participating in Healthcare Cost and Utilization Project Data State Inpatient Databases, implementation of Medicaid expansion was associated with increase in CRT rates among White individuals residing in states that adopted the Medicaid expansion policy. Further work is needed to address disparities in CRT among Black and Hispanic patients.

Abstract
Patients with heart failure (HF) are heterogeneous with various intrapersonal and interpersonal characteristics contributing to clinical outcomes. Bias, structural racism, and social determinants of health have been implicated in unequal treatment of patients with HF. Through several methodologies, artificial intelligence (AI) can provide models in HF prediction, prognostication, and provision of care, which may help prevent unequal outcomes. This review highlights AI as a strategy to address racial inequalities in HF; discusses key AI definitions within a health equity context; describes the current uses of AI in HF, strengths and harms in using AI; and offers recommendations for future directions.

Abstract
Background Cardiac resynchronization therapy (CRT) is beneficial in patients who have heart failure with reduced ejection fraction or arrhythmic events. However, most randomized controlled trials (RCTs) showing survival benefits primarily enrolled older white men. This study aims to evaluate CRT efficacy by sex, race, and age in RCTs. Methods Five electronic databases (CINAHL, Embase, Emcare, Medline, and PubMed) were searched from inception to July 12, 2021 for RCTs with CRT in adult patients. Data were analyzed for clinical outcomes including all-cause or cardiovascular (CV) death, worsening heart failure (HF), and HF hospitalization (HFH) according to sex, race, and age. Results Among six RCTs with up to moderate risk of bias, 54% (n = 3,630 of 6,682; mean age 64 years, 22% female, 8% black patients) had CRT device implantation. All-cause death (odds ratio [OR], 0.51; P = 0.053) was reduced in female versus male CRT patients, whereas CV death, HFH, or all-cause death with worsening HF or HFH did not differ significantly. No difference was seen in CRT patients for all-cause death and worsening HF (OR, 1.32; P = 0.46) among white vs black patients or for all-cause death and HFH (OR, 1.19; P = 0.55) among ≥ 65 versus < 65 years. Conclusions Whereas all-cause death was lower in female CRT patients, other reported outcomes did not significantly differ by sex, race, or age. Only 6 studies partially reported outcomes. Thus, enhanced reporting and analyses are required to overcome such paucity of data to evaluate the impact of these factors on clinical outcomes in distinct patient cohorts with CRT indication.

Abstract
This review summarizes racial and ethnic disparities in the quality of cardiovascular care-a challenge given the fragmented nature of the health care delivery system and measurement. Health equity for all racial and ethnic groups will not be achieved without a substantially different approach to quality measurement and improvement. The authors adapt a tool frequently used in quality improvement work-the driver diagram-to chart likely areas for diagnosing root causes of disparities and developing and testing interventions. This approach prioritizes equity in quality improvement. The authors demonstrate how this approach can be used to create interventions that reduce systemic racism within the institutions and professions that deliver health care; attends more aggressively to social factors related to race and ethnicity that affect health outcomes; and examines how hospitals, health systems, and insurers can generate effective partnerships with the communities they serve to achieve equitable cardiovascular outcomes.

Ntusi NAB, Sliwa K. Associations of Race and Ethnicity With Presentation and Outcomes of Hypertrophic Cardiomyopathy: JACC Focus Seminar 6/9. J Am Coll Cardiol 2021; 78:2573-2579. [PMID: 34887143 DOI: 10.1016/j.jacc.2021.10.020] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 09/29/2021] [Accepted: 10/05/2021] [Indexed: 12/26/2022]
Abstract
Significant racial and ethnicity-based disparities in clinical presentation, management, and outcome of hypertrophic cardiomyopathy (HCM) are reported. Black patients with HCM are more likely to present with heart failure but are less commonly referred for symptom management, sudden cardiac death stratification, surgical septal myectomy, or for implantable cardioverter-defibrillators, all interventions that increase survival. Prevalence of bystander cardiopulmonary resuscitation is lower for Black patients than for White patients. Black patients with HCM have decreased survival after hospital discharge following out-of-hospital cardiac arrest. Biomedical and social interventions are urgently needed to reduce ethnicity-based disparities, which have an impact on outcomes in HCM and other cardiovascular diseases. There is also a need to focus on implementation science to support durable adoption of evidence-based therapies in Black patients and communities.

Comparative Effectiveness of Dosing of Medical Therapy for Heart Failure: From the CHAMP-HF Registry. J Card Fail 2021; 28:370-384. [PMID: 34793971 DOI: 10.1016/j.cardfail.2021.08.023] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 07/30/2021] [Accepted: 08/15/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND The comparative effectiveness of differing doses of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) on clinical and patient-reported outcomes in US clinical practice is unknown. This study sought to characterize associations between dosing of GDMT and outcomes for patients with HFrEF in U.S. clinical practice METHODS: : This analysis included 4,832 US outpatients with chronic HFrEF across 150 practices in the CHAMP-HF registry with no contraindication and available dosing data for at least 1 GDMT at baseline. Baseline dosing of angiotensin-converting enzyme (ACEI)/ angiotensin II receptor blocker (ARB)/ angiotensin receptor-neprilysin inhibitor (ARNI), beta-blocker, and mineralocorticoid receptor antagonist (MRA) therapies were examined. For each medication class, multivariable models assessed associations between medication dosing and clinical outcomes over 24 months (all-cause mortality, HF hospitalization) and patient-reported outcomes at 12 months (change in Kansas City Cardiomyopathy Questionnaire Overall Summary Score [KCCQ-OS]). RESULTS After adjustment, compared with target dosing, lower dosing was associated with higher all-cause mortality for ACEI/ARB/ARNI (50% to <100% target dose, HR 1.16 [95% CI 0.87-1.55]; <50% target dose, HR 1.37 [95% CI 1.05-1.79]; none, HR 1.75 [95% CI 1.32-2.34; overall p<0.001) and beta-blocker (50% to <100% target dose, HR 1.30 [95% CI 1.00-1.69]; <50% target dose, HR 1.41 [95% CI 1.11-1.79; none, HR 1.24 [95% CI 0.92-1.67]; overall p=0.042). Lower dosing of ACEI/ARB/ARNI was independently associated with higher risk of HF hospitalization (50% to <100% target dose, HR 1.08 [95% CI 0.90-1.30]; <50% target dose, HR 1.23 [1.04-1.47]; none, HR 1.29 [1.04-1.60]; overall p=0.046), but beta-blocker dosing was not (overall p=0.085). Target dosing of MRA was not associated with risk of mortality or HF hospitalization. For each GDMT, compared with target dosing, lower dosing was not associated with change in KCCQ-OS at 12 months, with potential exception of worsening KCCQ-OS with lower dosing of ACEI/ARB/ARNI. CONCLUSIONS In this contemporary US outpatient HFrEF registry, target dosing of ACEI/ARB/ARNI and beta-blocker therapy was associated with reduced mortality, and variably associated with HF hospitalization and patient-reported outcomes. MRA dosing was not associated with outcomes. The totality of these findings support the benefits of target dosing of GDMT in routine practice, as tolerated, with unmeasured differences between patients receiving differing dosages potentially explaining differing results seen here compared with randomized clinical trials.

[PMID: 34615667 DOI: 10.1136/heartjnl-2021-319951] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 09/08/2021] [Indexed: 11/03/2022] Open
Abstract
OBJECTIVE To identify potential race, sex and age disparities in performance of transthoracic echocardiography (TTE) over several decades. METHODS TTE reports from five academic and community sites within a single integrated healthcare system were linked to 100% Medicare fee-for-service claims from 1 January 2005 to 31 December 2017. Multivariable Poisson regression was used to estimate adjusted rates of TTE utilisation after the index TTE according to baseline age, sex, race and comorbidities among individuals with ≥2 TTEs. Non-white race was defined as black, Asian, North American Native, Hispanic or other categories using Medicare-assigned race categories. RESULTS A total of 15 870 individuals (50.1% female, mean 72.2±12.7 years) underwent a total of 63 535 TTEs (range 2-55/person) over a median (IQR) follow-up time of 4.9 (2.4-8.5) years. After the index TTE, the median TTE use was 0.72 TTEs/person/year (IQR 0.43-1.33; range 0.12-26.76). TTE use was lower in older individuals (relative risk (RR) for 10-year increase in age, 0.91, 95% CI 0.89 to 0.92, p<0.001), women (RR 0.97, 95% CI 0.95 to 0.99, p<0.001) and non-white individuals (RR 0.95, 95% CI 0.93 to 0.97, p<0.001). Black women in particular had the lowest relative use of TTE (RR 0.92, 95% CI 0.88 to 0.95, p<0.001). The only clinical conditions associated with increased TTE use after multivariable adjustment were heart failure (RR 1.04, 95% CI 1.00 to 1.08, p=0.04) and chronic obstructive pulmonary disease (RR 1.05, 95% CI 1.00 to 1.10, p=0.04). CONCLUSIONS Among Medicare beneficiaries with multiple TTEs in a single large healthcare system, the median TTE use after the index TTE was 0.72 TTEs/person/year, although this varied widely. Adjusted for comorbidities, female sex, non-white race and advancing age were associated with decreased TTE utilisation.

Abstract
PURPOSE OF REVIEW This review discusses the current state of racial and ethnic inequities in heart failure burden, outcomes, and management. This review also frames considerations for bridging disparities to optimize quality heart failure care across diverse communities. RECENT FINDINGS Treatment options for heart failure have diversified and overall heart failure survival has improved with the advent of effective pharmacologic and nonpharmacologic therapies. With increased recognition, some racial/ethnic disparity gaps have narrowed whereas others in heart failure outcomes, utilization of therapies, and advanced therapy access persist or worsen. SUMMARY Racial and ethnic minorities have the highest incidence, prevalence, and hospitalization rates from heart failure. In spite of improved therapies and overall survival, the mortality disparity gap in African American patients has widened over time. Racial/ethnic inequities in access to cardiovascular care, utilization of efficacious guideline-directed heart failure therapies, and allocation of advanced therapies may contribute to disparate outcomes. Strategic and earnest interventions considering social and structural determinants of health are critically needed to bridge racial/ethnic disparities, increase dissemination, and implementation of preventive and therapeutic measures, and collectively improve the health and longevity of patients with heart failure.

Abstract
PURPOSE OF REVIEW This review highlights variability in prescribing of nonpharmacologic heart failure with reduced ejection fraction (HFrEF) therapies by race, ethnicity, and gender. The review also explores the evidence underlying these inequalities as well as potential mitigation strategies. RECENT FINDINGS There have been major advances in HF therapies that have led to improved overall survival of HF patients. However, racial and ethnic groups of color and women have not received equitable access to these therapies. Patients of color and women are less likely to receive nonpharmacologic therapies for HFrEF than White patients and men. Therapies including exercise rehabilitation, percutaneous transcatheter mitral valve repair, cardiac resynchronization therapy, heart transplant, and ventricular assist devices all have proven efficacy in patients of color and women but remain underprescribed. Outcomes with most nonpharmacologic therapy are similar or better among patients of color and women than White patients and men. System-level changes are urgently needed to achieve equity in access to nonpharmacologic HFrEF therapies by race, ethnicity, and gender.

Abstract
Importance Racial differences are recognized in multiple cardiovascular parameters, including left ventricular hypertrophy and heart failure, which are 2 major manifestations of hypertrophic cardiomyopathy. The association of race with disease expression and outcomes among patients with hypertrophic cardiomyopathy is not well characterized. Objective To assess the association between race, disease expression, care provision, and clinical outcomes among patients with hypertrophic cardiomyopathy. Design, Setting, and Participants This retrospective cohort study included data on black and white patients with hypertrophic cardiomyopathy from the US-based sites of the Sarcomeric Human Cardiomyopathy Registry from 1989 through 2018. Exposures Self-identified race. Main Outcomes and Measures Baseline characteristics; genetic architecture; adverse outcomes, including cardiac arrest, cardiac transplantation or left ventricular assist device implantation, implantable cardioverter-defibrillator therapy, all-cause mortality, atrial fibrillation, stroke, and New York Heart Association (NYHA) functional class III or IV heart failure; and septal reduction therapies. The overall composite outcome consists of the first occurrence of any component of the ventricular arrhythmic composite end point, cardiac transplantation, left ventricular assist device implantation, NYHA class III or IV heart failure, atrial fibrillation, stroke, or all-cause mortality. Results Of 2467 patients with hypertrophic cardiomyopathy at the time of analysis, 205 (8.3%) were black (130 male [63.4%]; mean [SD] age, 40.0 [18.6] years) and 2262 (91.7%) were white (1351 male [59.7%]; mean [SD] age, 45.5 [20.5] years). Compared with white patients, black patients were younger at the time of diagnosis (mean [SD], 36.5 [18.2] vs 41.9 [20.2] years; P < .001), had higher prevalence of NYHA class III or IV heart failure at presentation (36 of 205 [22.6%] vs 174 of 2262 [15.8%]; P = .001), had lower rates of genetic testing (111 [54.1%] vs 1404 [62.1%]; P = .03), and were less likely to have sarcomeric mutations identified by genetic testing (29 [26.1%] vs 569 [40.5%]; P = .006). Implantation of implantable cardioverter-defibrillators did not vary by race; however, invasive septal reduction was less common among black patients (30 [14.6%] vs 521 [23.0%]; P = .007). Black patients had less incident atrial fibrillation (35 [17.1%] vs 608 [26.9%]; P < .001). Black race was associated with increased development of NYHA class III or IV heart failure (hazard ratio, 1.45; 95% CI, 1.08-1.94) which persisted on multivariable Cox proportional hazards regression (hazard ratio, 1.97; 95% CI, 1.34-2.88). There were no differences in the associations of race with stroke, ventricular arrhythmias, all-cause mortality, or the overall composite outcome. Conclusions and Relevance The findings suggest that black patients with hypertrophic cardiomyopathy are diagnosed at a younger age, are less likely to carry a sarcomere mutation, have a higher burden of functionally limited heart failure, and experience inequities in care with lower use of invasive septal reduction therapy and genetic testing compared with white patients. Further study is needed to assess whether higher rates of heart failure may be associated with underlying ancestry-based disease pathways, clinical management, or structural inequities.

Abstract
IMPORTANCE Little is known about the association between industry payments and medical device selection. OBJECTIVE To examine the association between payments from device manufacturers to physicians and device selection for patients undergoing first-time implantation of a cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D). DESIGN, SETTING, AND PARTICIPANTS In this cross-sectional study, patients who received a first-time ICD or CRT-D device from any of the 4 major manufacturers (January 1, 2016-December 31, 2018) were identified. The data from the National Cardiovascular Data Registry ICD Registry was linked with the Open Payments Program's payment data. Patients were categorized into 4 groups (A, B, C, and D) corresponding to the manufacturer from which the physician who performed the implantation received the largest payment. For each patient group, the proportion of patients who received a device from the manufacturer that provided the largest payment to the physician who performed implantation was determined. Within each group, the absolute difference in proportional use of devices between the manufacturer that made the highest payment and the proportion of devices from the same manufacturer in the entire study cohort (expected prevalence) was calculated. EXPOSURES Manufacturers' payments to physicians who performed an ICD or CRT-D implantation. MAIN OUTCOMES AND MEASURES The primary outcome of the study was the manufacturer of the device used for the implantation. RESULTS Over a 3-year period, 145 900 patients (median age, 65 years; 29.6% women) received ICD or CRT-D devices from the 4 manufacturers implanted by 4435 physicians at 1763 facilities. Among these physicians, 4152 (94%) received payments from device manufacturers ranging from $2 to $323 559 with a median payment of $1211 (interquartile range, $390-$3702). Between 38.5% and 54.7% of patients received devices from the manufacturers that had provided physicians with the largest payments. Patients were substantially more likely to receive devices made by the manufacturer that provided the largest payment to the physician who performed implantation than they were from each other individual manufacturer. The absolute differences in proportional use from the expected prevalence were 22.4% (95% CI, 21.9%-22.9%) for manufacturer A; 14.5% (95% CI, 14.0%-15.0%) for manufacturer B; 18.8% (95% CI, 18.2%-19.4%) for manufacturer C; and 30.6% (95% CI, 30.0%-31.2%) for manufacturer D. CONCLUSIONS AND RELEVANCE In this cross-sectional study, a large proportion of ICD or CRT-D implantations were performed by physicians who received payments from device manufacturers. Patients were more likely to receive ICD or CRT-D devices from the manufacturer that provided the highest total payment to the physician who performed an ICD or CRT-D implantation than each other manufacturer individually.

Abstract
Importance Racial bias is associated with the allocation of advanced heart failure therapies, heart transplants, and ventricular assist devices. It is unknown whether gender and racial biases are associated with the allocation of advanced therapies among women. Objective To determine whether the intersection of patient gender and race is associated with the decision-making of clinicians during the allocation of advanced heart failure therapies. Design, Setting, and Participants In this qualitative study, 46 US clinicians attending a conference for an international heart transplant organization in April 2019 were interviewed on the allocation of advanced heart failure therapies. Participants were randomized to examine clinical vignettes that varied 1:1 by patient race (African American to white) and 20:3 by gender (women to men) to purposefully target vignettes of women patients to compare with a prior study of vignettes of men patients. Participants were interviewed about their decision-making process using the think-aloud technique and provided supplemental surveys. Interviews were analyzed using grounded theory methodology, and surveys were analyzed with Wilcoxon tests. Exposure Randomization to clinical vignettes. Main Outcomes and Measures Thematic differences in allocation of advanced therapies by patient race and gender. Results Among 46 participants (24 [52%] women, 20 [43%] racial minority), participants were randomized to the vignette of a white woman (20 participants [43%]), an African American woman (20 participants [43%]), a white man (3 participants [7%]), and an African American man (3 participants [7%]). Allocation differences centered on 5 themes. First, clinicians critiqued the appearance of the women more harshly than the men as part of their overall impressions. Second, the African American man was perceived as experiencing more severe illness than individuals from other racial and gender groups. Third, there was more concern regarding appropriateness of prior care of the African American woman compared with the white woman. Fourth, there were greater concerns about adequacy of social support for the women than for the men. Children were perceived as liabilities for women, particularly the African American woman. Family dynamics and finances were perceived to be greater concerns for the African American woman than for individuals in the other vignettes; spouses were deemed inadequate support for women. Last, participants recommended ventricular assist devices over transplantation for all racial and gender groups. Surveys revealed no statistically significant differences in allocation recommendations for African American and white women patients. Conclusions and Relevance This national study of health care professionals randomized to clinical vignettes that varied only by gender and race found evidence of gender and race bias in the decision-making process for offering advanced therapies for heart failure, particularly for African American women patients, who were judged more harshly by appearance and adequacy of social support. There was no associated between patient gender and race and final recommendations for allocation of advanced therapies. However, it is possible that bias may contribute to delayed allocation and ultimately inequity in the allocation of advanced therapies in a clinical setting.

Abstract
Background:
Left ventricular assist device (LVAD) therapy is an increasingly viable alternative for patients who are not candidates for heart transplantation or who are waiting for a suitable donor. We aimed to determine whether there is an association between sex, race/ethnicity, insurance coverage, and neighborhood income and access to/outcomes of LVAD implantation. We further analyzed whether access to LVAD improved in states that did versus did not expand Medicaid.
Methods and Results:
Retrospective cohort study using State Inpatient Databases to identify patients 18 to 85 years of age admitted for heart failure, cardiogenic shock, or LVAD implantation from 2012 to 2015. Logistic regression analyses adjusting for age, all the sociodemographic factors above, medical comorbidities, and a hospital random effect were used to quantify odds of receipt of LVADs, as well as outcomes conditional on receiving an LVAD, for the sociodemographic groups of interest. A total of 925 770 patients were included; 3972 (0.43%) received LVADs. After adjusting for age, comorbidities, and hospital effects, women (adjusted odds ratio [aOR], 0.45 [0.41–0.49]), black patients (aOR, 0.83 [0.74–0.92]), and Hispanic patients (aOR, 0.74 [0.64–0.87]) were less likely to receive LVADs than whites. Medicare (aOR, 0.79 [0.72–0.86]), Medicaid (aOR, 0.52 [0.46–0.58]), and uninsured patients (aOR, 0.17 [0.11–0.25]) were less likely to receive LVADs than the privately insured, and patients in low-income ZIP codes were less likely than those in higher income areas (aOR, 0.71 [0.65–0.77]). Among those who received LVADs, women (aOR, 1.78 [1.38–2.30]), patients of unknown race or race other than white, black, or Hispanic (aOR, 1.97 [1.42–2.74]), and uninsured patients (aOR, 4.86 [1.92–12.28]) had higher rates of in-hospital mortality. Medicaid expansion was not associated with an increase in LVAD implantation.
Conclusions:
There are meaningful sociodemographic disparities in access and outcomes for LVAD implantation. Medicaid expansion was not associated with an increase in LVAD rates.

Disparity in implantable cardioverter defibrillator therapy among minority South Asians in the United Kingdom. Heart 2020; 106:671-676. [PMID: 31924714 DOI: 10.1136/heartjnl-2019-315978] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 12/04/2019] [Accepted: 12/10/2019] [Indexed: 01/09/2023] Open
Abstract
OBJECTIVE There are large geographical differences in implantable cardioverter defibrillator (ICD) implantation rates for reasons not completely understood. In an increasingly multiethnic population, we sought out to investigate whether ethnicity influenced ICD implantation rates. METHODS This was a retrospective, cohort study of new ICD implantation or upgrade to ICD from January 2006 to February 2019 in recipients of Caucasian or South Asian ethnicity at a single tertiary centre in the UK. Data were obtained from a routinely collected local registry. Crude rates of ICD implantation were calculated for the population of Leicestershire county and were age-standardised to the UK population using the UK National Census of 2011. RESULTS The Leicestershire population was 980 328 at the time of the Census, of which 761 403 (77.7%) were Caucasian and 155 500 (15.9%) were South Asian. Overall, 2650 ICD implantations were performed in Caucasian (91.9%) and South Asian (8.1%) patients. South Asians were less likely than Caucasians to receive an ICD (risk ratio (RR) 0.43, 95% CI 0.37 to 0.49, p<0.001) even when standardised for age (RR 0.75, 95% CI 0.74 to 0.75, p<0.001). This remained the case for primary prevention indication (age-standardised RR 0.91, 95% CI 0.90 to 0.91, p<0.001), while differences in secondary prevention ICD implants were even greater (age-standardised RR 0.49, 95% CI 0.48 to 0.50, p<0.001). CONCLUSION Despite a universal and free healthcare system, ICD implantation rates were significantly lower in the South Asian than the Caucasian population residing in the UK. Whether this is due to cultural acceptance or an unbalanced consideration is unclear.

Abstract
Background Race influences medical decision making, but its impact on advanced heart failure therapy allocation is unknown. We sought to determine whether patient race influences allocation of advanced heart failure therapies. Methods and Results Members of a national heart failure organization were randomized to clinical vignettes that varied by patient race (black or white man) and were blinded to study objectives. Participants (N=422) completed Likert scale surveys rating factors for advanced therapy allocation and think‐aloud interviews (n=44). Survey results were analyzed by least absolute shrinkage and selection operator and multivariable regression to identify factors influencing advanced therapy allocation, including interactions with vignette race and participant demographics. Interviews were analyzed using grounded theory. Surveys revealed no differences in overall racial ratings for advanced therapies. Least absolute shrinkage and selection operator regression selected no interactions between vignette race and clinical factors as important in allocation. However, interactions between participants aged ≥40 years and black vignette negatively influenced heart transplant allocation modestly (−0.58; 95% CI, −1.15 to −0.0002), with adherence and social history the most influential factors. Interviews revealed sequential decision making: forming overall impression, identifying urgency, evaluating prior care appropriateness, anticipating challenges, and evaluating trust while making recommendations. Race influenced each step: avoiding discussing race, believing photographs may contribute to racial bias, believing the black man was sicker compared with the white man, developing greater concern for trust and adherence with the black man, and ultimately offering the white man transplantation and the black man ventricular assist device implantation. Conclusions Black race modestly influenced decision making for heart transplant, particularly during conversations. Because advanced therapy selection meetings are conversations rather than surveys, allocation may be vulnerable to racial bias.

Abstract
BACKGROUND Although device-based optimization has been developed to overcome the limitations of conventional optimization methods in cardiac resynchronization therapy (CRT), few real-world data supports the results of clinical trials that showed the efficacy of automatic optimization algorithms. We investigated whether CRT using the adaptive CRT algorithm is comparable to non-adaptive biventricular (BiV) pacing optimized with electrocardiogram or echocardiography-based methods. METHODS Consecutive 155 CRT patients were categorized into 3 groups according to the optimization methods: non-adaptive BiV (n = 129), adaptive BiV (n = 11), and adaptive left ventricular (LV) pacing (n = 15) groups. Additionally, a subgroup of patients (n = 59) with normal PR interval and left bundle branch block (LBBB) was selected from the non-adaptive BiV group. The primary outcomes included cardiac death, heart transplantation, LV assist device implantation, and heart failure admission. Secondary outcomes were electromechanical reverse remodeling and responder rates at 6 months after CRT. RESULTS During a median 27.5-month follow-up, there was no significant difference in primary outcomes among the 3 groups. However, there was a trend toward better outcomes in the adaptive LV group compared to the other groups. In a more rigorous comparisons among the patients with normal PR interval and LBBB, similar patterns were still observed. CONCLUSION In our first Asian-Pacific real-world data, automated dynamic CRT optimization showed comparable efficacy to conventional methods regarding clinical outcomes and electromechanical remodeling.

Abstract
Purpose: It is well known that minority patients, and particularly African Americans undergo lower rates of cardiac procedures than the white population, even when covered by equivalent insurance. Methods: We analyzed the rates of percutaneous transluminal coronary angioplasty (PTCA) for acute myocardial infarction (AMI) and for intermediate coronary syndrome (ICS), and rates of transcatheter aortic valve replacement for aortic stenosis in the 2012–2013 Medicare Limited Data Set (5% sample) file. Results: Although blacks have similar prevalence rates for AMI and ICS, they experience lower PTCA rates when compared with that of white patients (10.57 vs. 19.40, −46%). “Normalizing” procedure rates in the African American community to match their disease prevalence will require education and participation of all stakeholders: patients, providers, manufacturers, insurers, and advocacy organizations. Beyond improved clinical outcomes, financial incentives to “normalize care” exist. We estimate “lost” revenue within the Medicare population as a result of the lower procedure rates, at ∼$90 million annually ($22.0 million AMI, $9.4 million ICS and $68.7 million aortic valve disease). Conclusions: Providing evidence-based care to all patients improves health equity and can lower downstream high-cost conditions such as heart failure and multiple repeat inpatient admissions. As we move toward value-based care, the opportunity to normalize treatment for everyone seeking care is within our data analytics, innovative and collective reach.

Abstract
OBJECTIVES This study sought to determine whether the likelihood of receiving primary intensive care unit (ICU) care by a cardiologist versus a noncardiologist was greater for Caucasians than for African Americans admitted to an ICU for heart failure (HF). The authors further evaluated whether primary ICU care by a cardiologist is associated with higher in-hospital survival, irrespective of race. BACKGROUND Increasing data demonstrate an association between better HF outcomes and care by a cardiologist. It is unclear if previously noted racial differences in cardiology care persist in an ICU setting. METHODS Using the Premier database, adult patients admitted to an ICU with a primary discharge diagnosis of HF from 2010 to 2014 were included. Hierarchical logistic regression models were used to determine the association between race and primary ICU care by a cardiologist, adjusting for patient and hospital variables. Cox regression with inverse probability weighting was used to assess the association between cardiology care and in-hospital mortality. RESULTS Among 104,835 patients (80.3% Caucasians, 19.7% African Americans), Caucasians had higher odds of care by a cardiologist than African Americans (adjusted odds ratio: 1.42; 95% confidence interval: 1.34 to 1.51). Compared with a noncardiologist, primary ICU care by a cardiologist was associated with higher in-hospital survival (adjusted hazard ratio: 1.20, 95% confidence interval: 1.11 to 1.28). The higher likelihood of survival did not differ by patient race (interaction p = 0.32). CONCLUSIONS Among patients admitted to an ICU for HF, African Americans were less likely than Caucasians to receive primary care by a cardiologist. Primary care by a cardiologist was associated with higher survival for both Caucasians and African Americans.

Abstract
Background Prolonged QRS duration is associated with increased mortality among heart failure patients, but race or sex differences in QRS duration and associated effect on outcomes are unknown. Methods and Results We investigated QRS duration and morphology among 2463 black and white patients with heart failure and left ventricular ejection fraction ≤35% who underwent coronary angiography and 12‐lead electrocardiography at Duke University Hospital from 1995 through 2011. We used multivariable Cox regression models to assess the relationship between QRS duration and all‐cause mortality and investigate race‐QRS and sex‐QRS duration interaction. Median QRS duration was 105 ms (interquartile range [IQR], 92–132) with variation by race and sex (P<0.001). QRS duration was longest in white men (111 ms; IQR, 98–139) followed by white women (108 ms; IQR, 92–140), black men (100 ms; IQR, 91–120), and black women (94 ms; IQR, 86–118). Left bundle branch block was more common in women than men (24% vs 14%) and in white (21%) versus black individuals (12%). In black patients, there was a 16% increase in risk of mortality for every 10 ms increase in QRS duration up to 112 ms (hazard ratio, 1.16; 95% CI, 1.07, 1.25) that was not present among white patients (interaction, P=0.06). Conclusions Black individuals with heart failure had a shorter QRS duration and more often had non‐left bundle branch block morphology than white patients. Women had left bundle branch block more commonly than men. Among black patients, modest QRS prolongation was associated with increased mortality.

Abstract
Contrast-induced nephropathy (CIN) is an acute worsening of renal function after receiving intravascular contrast during a procedure. Some of the predisposing factors include underlying diabetes, chronic kidney disease, congestive heart failure, periprocedural hypotension, anemia, contrast volume, and osmolality of contrast; however, it remains unclear if risk varies for CIN with race and ethnicity. There is evidence in the literature showing the link between race/ethnicity and the discrepancies in the utilization of preventive care services and the resources related to cardiovascular and renal health. While these disparities continue to exist and affect some of the predictors of CIN, this review will explore the extent to which race and ethnicity directly affect CIN.

Abstract
Implantable cardiac pacing and defibrillation devices are effective and commonly used therapies for patients with cardiac rhythm disorders. Because device implantation is not easily reversible, as well as the high healthcare costs inherent in device use, a clear understanding of the clinical benefits relative to costs is essential for both appropriate clinical use and rational policy making. Cardiac implantable electronic devices (CIEDs) have been among the best-investigated therapies in medicine; these devices have been the topic of numerous clinical and economic evaluations during the past 30 years. However, many important questions remain unclarified. We review the evidence supporting the clinical benefits of CIEDs, including effectiveness in extending survival as well as improving quality of life. We also summarize the economic studies that have investigated costs associated with these devices and their overall cost effectiveness, and we highlight important potential areas for future research.

Comparative Efficacy of Cardiac Resynchronization Therapy in Africans Americans Compared With European Americans. Am J Cardiol 2015; 116:1101-5. [PMID: 26359119 DOI: 10.1016/j.amjcard.2015.07.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2015] [Revised: 07/03/2015] [Accepted: 07/03/2015] [Indexed: 11/17/2022]
Abstract
Race has seldomly been reported in the major clinical trials of cardiac resynchronization therapy (CRT). When described, African Americans (AAs) were substantially under-represented. This study sought to compare reverse ventricular remodeling and long-term outcomes in AAs versus European Americans (EAs) with advanced heart failure who underwent CRT. We extracted demographic (including race), clinical, and echocardiographic data on patients with advanced heart failure who underwent CRT with a left ventricular ejection fraction (LVEF) ≤35% and a QRS duration ≥120 ms. Long-term outcomes were compared between AAs and EAs. In patients in whom follow-up echocardiograms were available, improvement in LVEF (defined as an absolute improvement ≥5%) was compared between races. From a cohort of 662 patients, there were 88 AAs and 574 EAs. At a mean follow-up of 5.0 ± 2.5 years, survival rate free of left ventricular assist device (LVAD) and heart transplant was 54.5% for AAs and 53.8% for EAs (log-rank p = 0.997). In multivariate analysis, there was no difference in survival free of heart transplant or LVAD based on race (hazard ratio 1.1 [0.74 to 1.56], p = 0.72, EAs race as referent); 424 patients had a follow-up echocardiogram (55.4% EAs and 64.7% AAs). In multivariate analysis, there was no difference in the incidence of response based on race (1.1 [0.6 to 2.1, p = 0.80], EAs as referent). AAs derive similar benefits with CRT compared with EAs in terms of improvement in LVEF and long-term survival free of LVAD and heart transplant.

Abstract
The 20th century saw cardiovascular disease ascend as the leading cause of death in the world. In response to the new challenge that heart disease imposed, the cardiovascular community responded with ground breaking innovations in the form of evidence based medications that have improved survival, imaging modalities that allow for precise diagnosis and guide treatment; revascularization strategies that have not only reduced morbidity, but also improved survival following an acute myocardial infarction. However the benefits have not been distributed equitably and as a result disparities have arisen in cardiovascular care. There is tremendous data from the United States demonstrating the many phenotypical forms of disparities. This paper takes a global view of disparities and highlights that disparate care is not limited to the United States and it is another challenge that the medical community should rise and face head on.

Abstract
OBJECTIVES This study sought to describe the use of CRT-D and its association with survival for older patients. BACKGROUND Many patients who receive cardiac resynchronization therapy with defibrillator (CRT-D) in practice are older than those included in clinical trials. METHODS We identified patients undergoing ICD implantation in the National Cardiovascular Disease Registry (NCDR) ICD registry from 2006 to 2009, who also met clinical trial criteria for CRT, including left ventricular ejection fraction (LVEF) ≤35%, QRS ≥120 ms, and New York Heart Association (NYHA) functional class III or IV. NCDR registry data were linked to the social security death index to determine the primary outcome of time to death from any cause. We identified 70,854 patients from 1,187 facilities who met prior trial criteria for CRT-D. The mean age of the 58,147 patients receiving CRT-D was 69.4 years with 6.4% of patients age 85 or older. CRT use was 80% or higher among candidates in all age groups. Follow-up was available for 42,285 patients age ≥65 years at 12 months. RESULTS Receipt of CRT-D was associated with better survival at 1 year (82.1% vs. 77.1%, respectively) and 4 years (54.0% vs. 46.2% , respectively) than in those receiving only an ICD (p < 0.001). The CRT association with improved survival was not different for different age groups (p = 0.86 for interaction). CONCLUSIONS More than 80% of older patients undergoing ICD implantation who were candidates for a CRT-D received the combined device. Mortality in older patients undergoing ICD implantation was high but was lower for those receiving CRT-D.

Abstract
UNLABELLED POLICY POINTS: Racial/ethnic differences in the overuse of care (specifically, unneeded care that does not improve patients' outcomes) have received little scholarly attention. Our systematic review of the literature (59 studies) found that the overuse of care is not invariably associated with race/ethnicity, but when it was, a substantial proportion of studies found greater overuse of care among white patients. The absence of established subject terms in PubMed for the overuse of care or inappropriate care impedes the ability of researchers or policymakers to synthesize prior scientific or policy efforts. CONTEXT The literature on disparities in health care has examined the contrast between white patients receiving needed care, compared with racial/ethnic minority patients not receiving needed care. Racial/ethnic differences in the overuse of care, that is, unneeded care that does not improve patients' outcomes, have received less attention. We systematically reviewed the literature regarding race/ethnicity and the overuse of care. METHODS We searched the Medline database for US studies that included at least 2 racial/ethnic groups and that examined the association between race/ethnicity and the overuse of procedures, diagnostic (care) or therapeutic care. In a recent review, we identified studies of overuse by race/ethnicity, and we also examined reference lists of retrieved articles. We then abstracted and evaluated this information, including the population studied, data source, sample size and assembly, type of care, guideline or appropriateness standard, controls for clinical confounding and financing of care, and findings. FINDINGS We identified 59 unique studies, of which 11 had a low risk of methodological bias. Studies with multiple outcomes were counted more than once; collectively they assessed 74 different outcomes. Thirty-two studies, 6 with low risks of bias (LRoB), provided evidence that whites received more inappropriate or nonrecommended care than racial/ethnic minorities did. Nine studies (2 LRoB) found evidence of more overuse of care by minorities than by whites. Thirty-three studies (6 LRoB) found no relationship between race/ethnicity and overuse. CONCLUSIONS Although the overuse of care is not invariably associated with race/ethnicity, when it was, a substantial proportion of studies found greater overuse of care among white patients. Clinicians and researchers should try to understand how and why race/ethnicity might be associated with overuse and to intervene to reduce it.

Abstract
Significant racial/ethnic disparities have been documented in cardiovascular care. Although health care quality is improving for many Americans, differences in clinical outcomes have persisted between racial/ethnic minority patients and non-minorities, even when income, education level, and site of care are taken into consideration. Potential causes of disparities are complex and are related to differences in risk factor prevalence and control, use of evidence-based procedures and medications, and social and environmental factors. Minority patients are more likely to receive care from lower-quality health care providers and institutions and experience more barriers to accessing care. Factors such as stereotyping and bias in medicine are hard to quantify, but likely contribute to differences in treatment. Recent trends suggest that some disparities are decreasing. Opportunities for change and improvement exist for patients, providers, and health care systems. Promising interventions, such as health policy changes, quality improvement programs, and culturally targeted community and clinic-based interventions offer hope that high-quality health care in the USA can be provided to all patients.

Abstract
BACKGROUND Clinical trials have demonstrated benefit for cardiac resynchronization therapy (CRT) and implantable cardioverter-defibrillator (ICD) therapies in patients with heart failure with reduced ejection fraction (HFrEF); yet, questions have been raised with regard to the benefit of device therapy for minorities. OBJECTIVES The purpose of this study was to determine the clinical effectiveness of CRT and ICD therapies as a function of race/ethnicity in outpatients with HFrEF (ejection fraction ≤35%). METHODS Data from IMPROVE HF (Registry to Improve the Use of Evidence-Based Heart Failure Therapies in the Outpatient Setting) were analyzed by device status and race/ethnicity among guideline-eligible patients for mortality at 24 months. Multivariate Generalized Estimating Equations analyses were conducted, adjusting for patient and practice characteristics. RESULTS The ICD/cardiac resynchronization defibrillator (CRT-D)-eligible cohort (n = 7,748) included 3,391 (44%) non-Hispanic white, 719 (9%) non-Hispanic black, and 3,638 (47%) other racial/ethnic minorities or race-not-documented patients. The cardiac resynchronization pacemaker (CRT-P)/CRT-D-eligible cohort (n = 1,188) included 596 (50%) non-Hispanic white, 99 (8%) non-Hispanic black, and 493 (41%) other/not-documented patients. There was clinical benefit associated with ICD/CRT-D therapy (adjusted odds ratio: 0.64, 95% confidence interval: 0.52 to 0.79, p = 0.0002 for 24-month mortality), which was of similar proportion in white, black, and other minority/not-documented patients (device-race/ethnicity interaction p = 0.7861). For CRT-P/CRT-D therapy, there were also associated mortality benefits (adjusted odds ratio: 0.55, 95% confidence interval: 0.33 to 0.91, p = 0.0222), and the device-race/ethnicity interaction was not significant (p = 0.5413). CONCLUSIONS The use of guideline-directed CRT and ICD therapy was associated with reduced 24-month mortality without significant interaction by racial/ethnic group. Device therapies should be offered to eligible heart failure patients, without modification based on race/ethnicity.

Abstract
BACKGROUND Contemporary patterns of use and outcomes of implantable cardioverter-defibrillators (ICDs) in community practice settings are not well characterized. We assessed temporal trends in patient characteristics and outcomes among older patients undergoing primary prevention ICD therapy in US hospitals between 2006 and 2010. METHODS AND RESULTS Using the National Cardiovascular Data Registry's ICD Registry, we identified Medicare fee-for-service beneficiaries aged ≥65 years and older with left ventricular ejection fraction ≤35% who underwent primary prevention ICD implantation, including those receiving concomitant cardiac resynchronization therapy between 2006 and 2010 and could be matched to Medicare claims. Outcomes were mortality and hospitalization (all-cause and heart failure) at 180 days, and device-related complications. We used multivariable hierarchical logistic regression to assess temporal trends in outcomes accounting for changes in patient, physician, and hospital characteristics. The cohort included 117 100 patients. Between 2006 and 2010, only modest changes in patient characteristics were noted. Fewer single lead devices and more cardiac resynchronization therapy devices were used over time. Between 2006 and 2010, there were significant improvements in all outcomes, including 6-month all cause mortality (7.1% in 2006, 6.5% 2010; adjusted odds ratio, 0.88; 95% confidence interval, 0.82-0.95), 6-month rehospitalization (36.3% in 2006, 33.7% in 2010; adjusted odds ratio, 0.87; 95% confidence interval, 0.83-0.91), and device-related complications (5.8% in 2006, 4.8% in 2010; adjusted odds ratio, 0.80; 95% confidence interval, 0.74-0.88). CONCLUSIONS The clinical characteristics of this national population of Medicare patients undergoing primary prevention ICD implantation were stable between 2006 and 2010. Simultaneous improvements in outcomes suggest meaningful advances in the care for this patient population.

Abstract
BACKGROUND Peripartum cardiomyopathy (PPCM) is a rare and heterogeneous disease with a higher prevalence in African Americans (AAs) in the USA. The clinical features and prognosis of PPCM in AAs have not been sufficiently characterized. METHODS We studied 52 AA patients with PPCM and compared clinical characteristics and outcome with those of 104 white patients. RESULTS AA patients were significantly younger (26 ± 7 vs 30 ± 6 years; P < .001), had a higher prevalence of gestational hypertension (61% vs 41%; P = .03), and were diagnosed more commonly postpartum rather then antepartum (83% vs 64%; P = .03). The rate of left ventricular (LV) recovery (LV ejection fraction [LVEF] ≥50%) was significantly lower in AAs (40% vs 61%; P = .02). AA women also had a larger LV end-diastolic diameter (57 ± 10 vs 51 ± 6 mm; P = .004) as well as lower LVEF (40% ± 16.7% vs 46% ± 14%; P = .002) at the last follow-up. Moreover, AA patients had a significantly higher incidence of the combined end points of mortality and cardiac transplantation (P = .03) and showed a strong trend (P = .09) for increased mortality. CONCLUSIONS AA patients with PPCM in the USA have a different clinical profile and worse prognosis compared with white patients. Further research to evaluate potentially correctable causes for these differences is warranted.
