African American recruitment in early heart failure palliative care trials: outcomes and comparison with the ENABLE CHF-PC randomized trial.
This study examined African American (AA) clinical trial recruitment and enrollment in a palliative care randomized controlled trial (RCT) for heart failure (HF) patients and compared patient baseline characteristics to other HF palliative care RCTs. The authors used the ENABLE CHF-PC (Educate, Nurture, Advise, Before Life Ends: Comprehensive Heartcare for Patients and Caregivers) RCT using bivariate statistics to compare racial and patient characteristics and differences through recruitment stages. They then compared the baseline sample characteristics among three palliative HF trials. They screened 785 patients, of whom 566 with NYHA classification III-IV were approached, with 461 enrolled and then 415 randomized. African Americans were more likely to consent than Caucasians (55%), were younger, had a lower ejection fraction, were more likely to be single, and lack an advanced directive. AAs reported higher goal setting, care coordination, and used more “denial” coping strategies. Compared to two recent HF RCTs, the ENABLE CHF-PC sample had a higher proportion of AAs.

Disparities in 5-year outcomes and imaging surveillance following elective endovascular repair of abdominal aortic aneurysm by sex, race, and ethnicity.
The purpose of this study was to identify variations in 5-year outcomes and imaging surveillance after elective endovascular aortic aneurysm repair (EVAR) by sex, race, and ethnicity and to examine possible mechanisms contributing to these variations. The primary outcome was 5-year aneurysm rupture. Secondary outcomes were 5-year reintervention and mortality, and having no aortic imaging follow-up from 6 to 24 months after EVAR. The study found that among 16,040 patients, 73% were White males, 18% were White females, 2.6% were Black males, 1.1% were Black females, 0.9% were Asian males, 0.2% were Asian females, 1.7% were Hispanic males, and 0.4% were Hispanic females. At 5 years, Black females had the highest rupture rates at 6.4% and white males had the lowest at 2.3%. Compared with White males, rupture rates were higher in White females, Black females, and Asian females. Among other groups, Black males had higher reintervention and both Black and Hispanic males had higher rates of no imaging follow-up. In adjusted analyses, White, Black, and Asian females remained at significantly higher risk for 5-year rupture. The researchers concluded that Black females had higher 5-year aneurysm rupture, reintervention, and mortality rates after elective EVAR as compared with White male patients, whereas White females had higher rupture, mortality and loss-to-imaging-follow-up compared to White male patients. Black males had higher reintervention and no imaging follow-up, and Asian females had higher rupture rates.

Disparities in reporting and representation by sex, race, and ethnicity in endovascular aortic device trials.
The purpose of this study was to examine the demographics of patients enrolled in critical U.S. endovascular aortic device trials to explore the representation of vulnerable populations, including women and racial and ethnic minorities. The primary outcomes included the percentage of trials reporting participant sex, race, and ethnicity and the percentage of participants across sex, racial, and ethnic groups. The study found that the Food and Drug Administration (FDA) provided 29 approvals from 29 trials of 24 devices with a total of 4046 patients: 52% (15) were EVAR devices, 41% (12) were TEVAR devices, and 3.4% (1) was a FEVAR device, with 1 dissection stent (3.4%). Fifty-two percent of the trials reported the three most common racial groups (White, Black, Asian), and 48% reported Hispanic ethnicity. The TEVAR trials were the most likely to report all three racial groups and Hispanic ethnicity (92% and 75%, respectively), while the EVAR trials had the lowest reporting rates (13% and 20%, respectively). The median female enrollment was 21%, with the EVAR trials having the lowest female enrollment compared with 41% in the TEVAR trials, 21% in the FEVAR trial, and 34% in the dissection stent trial. The study concluded that in critical aortic device trials that led to FDA approval, female patients were underrepresented, especially for EVAR, and racial and ethnic minority groups were under-represented and underreported.

Association of race and gender with primary caregiver relationships and eligibility for advanced heart failure therapies.
Caregiver support is considered necessary after heart transplant (HT) and left ventricular assist device (LVAD) for patients with end-stage heart failure (HF). Few studies have demonstrated how caregivers differ by gender and race, and whether that impacts therapy eligibility. In this study, the investigators examined caregiver relationships among 674 patients (32% women, 55% Black) evaluated at Emory University from 2011 to 2017.

Exploring culturally responsive religious and spirituality health care communications among African Americans with advanced heart failure, their family caregivers, and clinicians.
This study explored how religion and spirituality (R/S) impacts the ways that African Americans (AAs) cope with serious illness. In particular, this study looks at AAs with advanced heart failure and their family caregivers’ (FCGs) preferences about R/S in patient-clinician communication. Transcribed interviews were analyzed to identify emergent themes. AA patient participants (n = 15) were a mean age of 62, 40% female, and 87% had >high school diploma/GED. AA FCGs (n = 14) were a mean age of 58, 93% female, 93% had >high school diploma/GED, and 86% were unemployed. Most caregivers were patients’ spouses/partners. All participants were Protestants. Patients and FCGs perspectives differed in relation to inclusion of R/S in health care communication. Patients felt that R/S should not be discussed in clinical encounters and discussed only if patient initiated. FCGs felt that clinicians’ R/S communication is not a priority, but clinicians should openly acknowledge patients’ R/S beliefs and should engage in R/S conversations with patients.

Provider care team segregation and operative mortality following coronary artery bypass grafting.
The purpose of this study was to examine whether provider care team segregation within hospitals contributes to the higher mortality rate of Black patients following coronary artery bypass grafting compared to their White counterparts. Using national Medicare data, findings showed that Black patients who undergo coronary artery bypass grafting at a hospital with a higher level of provider care team segregation die more frequently after surgery than Black patients treated at a hospital with a lower level.

Excess 30-day heart failure readmissions and mortality in black patients increases with neighborhood deprivation.
Researchers examined whether neighborhood environment modifies the disparity in 30-day heart failure (HF) readmissions and mortality between Black and White patients in the Southeastern United States. They created a geocoded retrospective cohort of patients hospitalized for acute HF from 2010-2018 within Emory Healthcare. They found that excess 30-day HF readmissions and mortality were present among Black patients in every neighborhood strata and increased with progressive neighborhood socioeconomic deprivation.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.

Refining stroke prediction in atrial fibrillation patients by addition of African-American ethnicity to CHA2DS2-VASc score.
The authors hypothesized that the addition of African-American ethnicity to the CHA2DS2-VASc score might improve stroke prediction in patients with atrial fibrillation (AF). They found that, in patients over age 65 with newly diagnosed AF, the addition of ethnicity to CHA2DS2-VASc score significantly improved stroke prediction.

Prevalence of masked hypertension and its association with subclinical cardiovascular disease in African Americans: results from the Jackson Heart Study.
Using data from the Jackson Heart Study, an exclusively African American population-based cohort, the researchers evaluated the association of masked hypertension and prehypertension with left ventricular mass index and common carotid intima media thickness. Masked hypertension was common among African Americans with prehypertension and also normal clinic blood pressure, and was associated with subclinical cardiovascular disease.

Effect of race on outcomes (stroke and death) in patients >65 years with atrial fibrillation.
The researchers sought to determine whether there are any racial differences in the outcomes of death and stroke in patients with newly diagnosed AF in patients >65 years. They found that the risks of death and stroke are higher in blacks and Hispanics compared with whites. The increased risk was eliminated or significantly reduced after adjusting for preexisting co-morbidities.
