Access to durable LVAD therapy for patients with limited social support: Surveying program-specific approaches.

Racial and ethnic disparities in provision of left ventricular assist device (LVAD) therapy have been identified. These disparities may be at least partially related to socioeconomic factors, including social support networks and financial constraints. This study aimed to identify specific barriers, and variations in institutional approaches, to the provision of equitable care to underserved populations. A survey was administered to 237 LVAD program personnel, including physicians, LVAD coordinators, and social workers, at more than 100 LVAD centers across 7 countries. Three fourths of respondents reported that their program required a support person to live with the LVAD patient for some period of time following implantation. In addition, 31% of respondents reported that patients with the inability to pay for medications are turned down at their program. The most significant barriers to successful LVAD implantation were lack of social support, lack of insurance, and lack of timely referral. The most consistently identified supports needed from the hospital system for success in underserved populations were the provision of a solution for patient transportation to and from hospital visits and the provision of financial support. This survey highlights the challenges facing LVAD programs that care for underserved patient populations and sets the stage for specific interventions aimed at reducing disparities in access to care.

Mild antecedent COVID-19 associated with symptom-specific post-acute sequelae.

BACKGROUND: The impact of COVID-19 severity on development of long-term sequelae remains unclear, and symptom courses are not well defined. METHODS: This ambidirectional cohort study recruited adults with new or worsening symptoms lasting ≥3 weeks from confirmed SARS-CoV-2 infection between August 2020-December 2021. COVID-19 severity was defined as severe for those requiring hospitalization and mild for those not. Symptoms were collected using standardized questionnaires. Multivariable logistical regression estimated odds ratios (OR) and 95% confidence intervals (CI) for associations between clinical variables and symptoms. RESULTS: Of 332 participants enrolled, median age was 52 years (IQR 42-62), 233 (70%) were female, and 172 (52%) were African American. Antecedent COVID-19 was mild in 171 (52%) and severe in 161 (48%). In adjusted models relative to severe cases, mild COVID-19 was associated with greater odds of fatigue (OR:1.83, CI:1.01-3.31), subjective cognitive impairment (OR:2.76, CI:1.53-5.00), headaches (OR:2.15, CI:1.05-4.44), and dizziness (OR:2.41, CI:1.18-4.92). Remdesivir treatment was associated with less fatigue (OR:0.47, CI:0.26-0.86) and fewer participants scoring >1.5 SD on PROMIS Cognitive scales (OR:0.43, CI:0.20-0.92). Fatigue and subjective cognitive impairment prevalence was higher 3-6 months after COVID-19 and persisted (fatigue OR:3.29, CI:2.08-5.20; cognitive OR:2.62, CI:1.67-4.11). Headache was highest at 9-12 months (OR:5.80, CI:1.94-17.3). CONCLUSIONS: Mild antecedent COVID-19 was associated with highly prevalent symptoms, and those treated with remdesivir developed less fatigue and cognitive impairment. Sequelae had a delayed peak, ranging 3-12 months post infection, and many did not improve over time, underscoring the importance of targeted preventative measures.

Utilizing Artificial Intelligence to Enhance Health Equity Among Patients with Heart Failure.

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.

Racial differences in cardiopulmonary outcomes of hospitalized COVID-19 patients with acute kidney injury.

In-hospital acute kidney injury (IH-AKI) has been reported in a significant proportion of patients with COVID-19 and is associated with increased disease burden and poor outcomes. However, the mechanisms of injury are not fully understood. We sought to determine the significance of race on cardiopulmonary outcomes and in-hospital mortality of hospitalized COVID-19 patients with AKI. We conducted a retrospective cohort study of consecutive patients hospitalized in Grady Health System in Atlanta, Georgia between February and July 2020, who tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) on qualitative polymerase-chain-reaction assay. We evaluated the primary composite outcome of in-hospital cardiac events, and mortality in blacks with AKI versus non-blacks with AKI. In a subgroup analysis, we evaluated the impact of AKI in all blacks and in all non-blacks. Of 293 patients, effective sample size was 267 after all exclusion criteria were applied. The mean age was 61.4 ± 16.7, 39% were female, and 75 (28.1%) had IH-AKI. In multivariable analyses, blacks with IH-AKI were not more likely to have in-hospital cardiac events (aOR 0.3, 95% Confidence interval (CI) 0.04-1.86, p = 0.18), require ICU stay (aOR 0.80, 95% CI 0.20-3.25, p = 0.75), acute respiratory distress syndrome (aOR 0.77, 95% CI 0.16-3.65, p = 0.74), require mechanical ventilation (aOR 0.51, 95% CI 0.12-2.10, p = 0.35), and in-hospital mortality (aOR 1.40, 95% CI 0.26-7.50, p = 0.70) when compared to non-blacks with IH-AKI. Regardless of race, the presence of AKI was associated with worse outcomes. Black race is not associated with higher risk of in-hospital cardiac events and mortality in hospitalized COVID-19 patients who develop AKI. However, blacks with IH-AKI are more likely to have ARDS or die from any cause when compared to blacks without IH-AKI.

Improving the enrollment of women and racially/ethnically diverse populations in cardiovascular clinical trials: An ASPC practice statement.

Cardiovascular disease (CVD) remains the leading cause of death for both women and men worldwide. In the United States (U.S.), there are significant disparities in cardiovascular risk factors and CVD outcomes among racial and ethnic minority populations, some of whom have the highest U.S. CVD incidence and mortality. Despite this, women and racial/ethnic minority populations remain underrepresented in cardiovascular clinical trials, relative to their disease burden and population percentage. The lack of diverse participants in trials is not only a moral and ethical issue, but a scientific concern, as it can limit application of future therapies. Providing comprehensive demographic data by sex and race/ethnicity and increasing representation of diverse participants into clinical trials are essential in assessing accurate drug response, safety and efficacy information. Additionally, diversifying investigators and clinical trial staff may assist with connecting to the language, customs, and beliefs of study populations and increase recruitment of participants from diverse backgrounds. In this review, a working group for the American Society for Preventive Cardiology (ASPC) reviewed the literature regarding the inclusion of women and individuals of diverse backgrounds into cardiovascular clinical trials, focusing on prevention, and provided recommendations of best practices for improving enrollment to be more representative of the U.S. society into trials.

Ten things to know about ten cardiovascular disease risk factors.

Given rapid advancements in medical science, it is often challenging for the busy clinician to remain up-to-date on the fundamental and multifaceted aspects of preventive cardiology and maintain awareness of the latest guidelines applicable to cardiovascular disease (CVD) risk factors. The "American Society for Preventive Cardiology (ASPC) Top Ten CVD Risk Factors 2021 Update" is a summary document (updated yearly) regarding CVD risk factors. This "ASPC Top Ten CVD Risk Factors 2021 Update" summary document reflects the perspective of the section authors regarding ten things to know about ten sentinel CVD risk factors. It also includes quick access to sentinel references (applicable guidelines and select reviews) for each CVD risk factor section. The ten CVD risk factors include unhealthful nutrition, physical inactivity, dyslipidemia, hyperglycemia, high blood pressure, obesity, considerations of select populations (older age, race/ethnicity, and sex differences), thrombosis/smoking, kidney dysfunction and genetics/familial hypercholesterolemia. For the individual patient, other CVD risk factors may be relevant, beyond the CVD risk factors discussed here. However, it is the intent of the "ASPC Top Ten CVD Risk Factors 2021 Update" to provide a succinct overview of things to know about ten common CVD risk factors applicable to preventive cardiology.

Pre-existing cardiovascular disease, acute kidney injury, and cardiovascular outcomes in hospitalized blacks with COVID-19 infection.

BACKGROUND: The Corona Virus 19 (COVID-19) infection is associated with worse outcomes in blacks, although the mechanisms are unclear. We sought to determine the significance of black race, pre-existing cardiovascular disease (pCVD), and acute kidney injury (AKI) on cardiopulmonary outcomes and in-hospital mortality of COVID-19 patients. METHODS: We conducted a retrospective cohort study of blacks with/without pCVD and with/without in-hospital AKI, hospitalized within Grady Memorial Hospital in Georgia between February and July 2020, who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on qualitative polymerase-chain-reaction assay. The primary outcome was a composite of in-hospital cardiac events. RESULTS: Of the 293 patients hospitalized with COVID-19 in this study, 71 were excluded from the primary analysis (for race/ethnicity other than black non-Hispanic). Of the 222 hospitalized COVID-19 patients included in our analyses, 41.4% were female, 78.8% had pCVD, and 30.6% developed AKI during the admission. In multivariable analyses, pCVD (OR 4.7, 95% CI 1.5-14.8, P=0.008) and AKI (OR 2.7, 95% CI 1.3-5.5, P=0.006) were associated with increased odds of in-hospital cardiac events. AKI was associated with increased odds of in-hospital mortality (OR 8.9, 95% CI 3.3-23.9, P<0.0001). The presence of AKI was associated with increased odds of ICU stay, mechanical ventilation, and acute respiratory distress syndrome (ARDS). CONCLUSION: pCVD and AKI were associated with higher risk of in-hospital cardiac events, and AKI was associated with a higher risk of in-hospital mortality in blacks.

State-of-the-Art review: Hypertension practice guidelines in the era of COVID-19.

The global burden of hypertension (HTN) is immense and increasing. In fact, HTN is the leading risk factor for adverse cardiovascular disease outcomes. Due to the critical significance and increasing prevalence of the disease, several national and international societies have recently updated their guidelines for the diagnosis and treatment of HTN. In consideration of the COVID-19 pandemic, this report provides clinicians with the best strategies to prevent HTN, manage the acute and long-term cardiac complications of HTN, and provide the best evidence-based care to patients in an ever-changing healthcare environment. The overarching goal of the various HTN guidelines is to provide easily accessible information to healthcare providers and public health officials, which is key for optimal clinical practice. However, the COVID-19 pandemic has challenged the ability to provide safe care to the most vulnerable hypertensive populations throughout the world. Therefore, this review compares the most recent guidelines of the 2017 American College of Cardiology/American Heart Association and multiple U.S. societies, the 2018 European Society of Cardiology/European Society of Hypertension, the 2019 National Institute for Care and Health Excellence, and the 2020 International Society of Hypertension. While a partial emphasis is placed on the management of HTN in the midst of COVID-19, this review will summarize current concepts and emerging data from the listed HTN guidelines on the diagnosis, monitoring, management, and evidence-based treatments in adults.

Clinical trial evidence for treatment of depression in heart failure.

Depression is an important disease state that requires a significant amount of time and resources for proper management. The presence of depression in patients with cardiovascular disease has been strongly associated with detrimental effects in terms of morbidity and mortality. Little is known about the management of depression in heart failure patients, although several investigators continue to pursue optimal treatment strategies for depression in this population. While limited, the prospective clinical trial data evaluating interventions for depression management in patients with heart failure continue to produce promising findings for progressive and improved management of both depression and heart failure.

Depression after myocardial infarction.

Depression is an important disease state that requires significant time and resources to manage properly. The presence of depression in patients with cardiovascular disease has been strongly associated with detrimental effects in terms of morbidity and mortality. Although several large-scale and small studies have evaluated various interventions in the management of depression after myocardial infarction, a significant portion of these data have provided more questions than answers. Although limited, the randomized prospective clinical trial data evaluating interventions for the management of depression after myocardial infarction in patients with ischemic heart disease continue to produce promising findings for progressive and improved management of these devastating diseases.

Racial differences among high-risk patients presenting with non-ST-segment elevation acute coronary syndromes (results from the SYNERGY trial).

Management and outcomes of patients with acute coronary syndromes (ACSs) may vary according to patient race and ethnicity. To assess racial differences in presentation and outcome in high-risk North American patients with non-ST-segment elevation (NSTE) ACS, we analyzed baseline racial/ethnic differences and all-cause death or nonfatal myocardial infarction (MI) in 6,077 white, 586 African-American, and 344 Hispanic patients through 30-day, 6-month, and 1-year follow-up. Frequencies of hypertension were 66% for whites, 83% for African-Americans, and 78% for Hispanics (overall p <0.001). Use of angiography was similar across groups. Use of percutaneous coronary intervention (46% for whites, 41% for African-Americans, and 45% for Hispanics, overall p = 0.046) and coronary artery bypass grafting (20% for whites, 16% for African-Americans, and 22% for Hispanics, overall p = 0.044) differed. African-American patients had significantly fewer diseased vessels compared with white patients (p = 0.0001). Thirty-day death or MI was 14% for whites, 10% for African-Americans, and 14% for Hispanics (overall p = 0.034). After adjustment for baseline variables, African-American patients had lower 30-day death or MI compared with white patients (odds ratio 0.73, 95% confidence interval 0.55 to 0.98). There were no differences in 6-month death or MI across racial/ethnic groups. In conclusion, baseline clinical characteristics differed across North American racial/ethnic groups in the SYNERGY trial. African-American patients had significantly better adjusted 30-day outcomes but similar 6-month outcomes compared with white patients.

Racial differences in the characteristics of patients admitted for acute decompensated heart failure and their relation to outcomes: results from the OPTIME-CHF trial.

BACKGROUND: Recent data suggest that differences in response to therapy and survival exist between African Americans and Caucasians with heart failure. Whether these differences exist in acute decompensated heart failure (ADHF) is uncertain. METHODS AND RESULTS: We analyzed data from the OPTIME-CHF (Outcomes of a Prospective Trial of Intravenous Milrinone for Exacerbations of Chronic Heart Failure) study, a randomized trial of intravenous milrinone versus placebo in 949 patients hospitalized with ADHF. We evaluated differences in clinical characteristics, outcomes, and response to milrinone therapy in African American patients compared with Caucasians. The primary end point of OPTIME-CHF was days hospitalized for cardiovascular causes or death within 60 days of randomization. Thirty-three percent (n = 310) of patients were African American. African American patients were younger (57 vs. 70 years, P < .0001) and more likely to have non-ischemic cardiomyopathy (74% vs. 36%, P < .0001). In unadjusted analysis, African American patients had a lower 60-day mortality (5% vs. 12%, P = .0004) and tended to have better overall clinical outcomes. After adjustment for baseline differences, however, these differences were no longer significant. We found no differential effect of milrinone therapy by race. CONCLUSION: African American patients with acute decompensated heart failure present with a different clinical profile than Caucasian patients. Although unadjusted clinical outcomes are better for African Americans presenting with ADHF, these differences diminished after adjustment for baseline characteristics.

Isosorbide dinitrate-hydralazine combination therapy in African Americans with heart failure.

Despite significant improvement in therapy and management, heart failure remains a worrisome disease state that is especially problematic in special populations. African Americans suffer a disproportionately higher prevalence of heart failure when compared to other populations. It has been recently demonstrated that vasodilator therapy using the combination of isosorbide dinitrate (ISDN) and hydralazine (HYD) as an adjunct to background evidence-based therapy appears to display the strongest signal of benefit in reducing mortality and morbidity in the African American population. Through review of the retrospective and more recent prospective data, we will focus on the benefit of ISDN-HYD as adjunctive therapy for use in African Americans with systolic heart failure on concomitant appropriate evidence based therapy. This review also closely examines some of the potential contributions to endothelial dysfunction in African Americans, and the relationship of vascular homeostasis and nitric oxide. The role of oxidative stress in left ventricular dysfunction will also be explored as a reduction of oxidative stress offers particular promise in the management of heart failure. Although neurohormonal blockade has been responsible for notable event reductions in patients with systolic heart failure, the addition of ISDN-HYD, vasodilator therapy that enhances nitric oxide and reduces oxidative stress, further improves quality of life and survival in African American patients with heart failure. These findings strongly imply that nitric oxide enhancement and/or oxidative stress reduction may be important new therapeutic directions in the management of heart failure.
