Implementation of Obesity Science Into Clinical Practice: A Scientific Statement From the American Heart Association.

Obesity is a recognized public health epidemic with a prevalence that continues to increase dramatically in nearly all populations, impeding progress in reducing incidence rates of cardiovascular disease. Over the past decade, obesity science has evolved to improve knowledge of its multifactorial causes, identifying important biological causes and sociological determinants of obesity. Treatments for obesity have also continued to develop, with more evidence-based programs for lifestyle modification, new pharmacotherapies, and robust data to support bariatric surgery. Despite these advancements, there continues to be a substantial gap between the scientific evidence and the implementation of research into clinical practice for effective obesity management. Addressing barriers to obesity science implementation requires adopting feasible methodologies and targeting multiple levels (eg, clinician, community, system, policy) to facilitate the delivery of obesity-targeted therapies and maximize the effectiveness of guideline-driven care to at-need patient populations. This scientific statement (1) describes strategies shown to be effective or promising for enhancing translation and clinical application of obesity-based research; (2) identifies key gaps in the implementation of obesity science into clinical practice; and (3) provides guidance and resources for health care professionals, health care systems, and other stakeholders to promote broader implementation and uptake of obesity science for improved population-level obesity management. In addition, advances in implementation science that hold promise to bridge the know-do gap in obesity prevention and treatment are discussed. Last, this scientific statement highlights implications for health research policy and future research to improve patient care models and optimize the delivery and sustainability of equitable obesity-related care.

Chronotropic Incompetence among People with HIV Improves with Exercise Training in the Exercise for Healthy Aging Study.

BACKGROUND: People with HIV (PWH) have lower exercise capacity compared to peers without HIV, which may be explained by chronotropic incompetence (CI), the inability to increase heart rate during exercise. METHODS: The Exercise for Healthy Aging Study included adults ages 50-75 with and without HIV. Participants completed 12 weeks of moderate intensity exercise, before randomization to moderate or high intensity for 12 additional weeks. We compared adjusted heart rate reserve (AHRR; CI <80%) on cardiopulmonary exercise testing by HIV serostatus and change from baseline to 12 and 24 weeks using mixed effects models. RESULTS: Among 32 PWH and 37 controls (median age 56, 7% female, mean BMI 28 kg/m2), 28% of PWH compared to 11% of controls had CI at baseline (p = 0.067). AHRR was lower among PWH (91 vs 101%; difference 10%, 95% CI 1.9-18.9; p = 0.02). At week 12, AHRR normalized among PWH (+8%, 95% CI 4-11; p < 0.001) and was sustained at week 24 (+5, 95%CI 1-9; p = 0.008) compared to no change among controls (95%CI -4 to 4; p = 0.95; pinteraction = 0.004). After 24 weeks of exercise, only 15% PWH and 10% of controls had CI (p = 0.70). CONCLUSIONS: Chronotropic incompetence contributes to reduced exercise capacity among PWH and improves with exercise training.

Longitudinal Changes in Subclinical Vascular Disease in Ugandan Youth With Human Immunodeficiency Virus.

BACKGROUND: Prospective investigations on the risk of cardiovascular disease among youth with perinatally acquired human immunodeficiency virus (PHIV) in sub-Saharan Africa are lacking. METHODS: A prospective observational cohort study was performed in 101 youth (aged 10-18 years) with PHIV and 97 who were human immunodeficiency virus (HIV) uninfected (HIV-), from 2017 to 2021 at the Joint Clinical Research Center in Uganda. Participants with PHIV were receiving antiretroviral therapy (ART) and had HIV-1 RNA levels ≤400 copies/mL. The common carotid artery intima-media thickness (IMT) and pulse wave velocity (PWV) were evaluated at baseline and at 96 weeks. Groups were compared using unpaired t-test, and potential predictors of IMT and PWV were assessed using quantile regression. RESULTS: Of the 198 participants recruited at baseline, 168 (89 with PHIV, 79 HIV-) had measurements at 96 weeks. The median age (interquartile range) age was 13 (11-15) years; 52% were female, and 85% had viral loads <50 copies/mL that remained undetectable at week 96. The baseline mean common carotid artery IMT was slightly higher in participants with PHIV compared with controls (P < .01), and PWV did not differ between groups (P = .08). At week 96, IMT decreased and PWV increased in the PHIV group (P ≤ .03); IMT increased in the HIV- group (P = .03), with no change in PWV (P = .92). In longitudinal analyses in those with PHIV, longer ART duration was associated with lower PWV (ß = .008 [95% confidence interval, -.008 to .003]), and abacavir use with greater IMT (ß = .043 [.012-.074]). CONCLUSIONS: In healthy Ugandan youth with PHIV, virally suppressed by ART, the common carotid artery IMT did not progress over 2 years. Prolonged and early ART may prevent progression of subclinical vascular disease, while prolonged use of abacavir may increase it.

Interleukin 6 Blockade With Tocilizumab Diminishes Indices of Inflammation That Are Linked to Mortality in Treated Human Immunodeficiency Virus Infection.

BACKGROUND: People with human immunodeficiency virus (PWH) are at increased risk for comorbidities, and plasma interleukin 6 (IL-6) levels are among the most robust predictors of these outcomes. Tocilizumab (TCZ) blocks the receptor for IL-6, inhibiting functions of this cytokine. METHODS: This was a 40-week, placebo-controlled, crossover trial (NCT02049437) where PWH on stable antiretroviral therapy (ART) were randomized to receive 3 monthly doses of TCZ or matching placebo intravenously. Following a 10-week treatment period and a 12-week washout, participants were switched to the opposite treatment. The primary endpoints were safety and posttreatment levels of C-reactive protein (CRP) and CD4+ T-cell cycling. Secondary endpoints included changes in inflammatory indices and lipid levels. RESULTS: There were 9 treatment-related toxicities of grade 2 or greater during TCZ administration (mostly neutropenia) and 2 during placebo administration. Thirty-one of 34 participants completed the study and were included in a modified intent-to-treat analysis. TCZ reduced levels of CRP (median decrease, 1819.9 ng/mL, P < .0001; effect size, 0.87) and reduced inflammatory markers in PWH, including D-dimer, soluble CD14, and tumor necrosis factor receptors. T-cell cycling tended to decrease in all maturation subsets after TCZ administration, but was only significant among naive CD4 T cells. Lipid levels, including lipid classes that have been related to cardiovascular disease risk, increased during TCZ treatment. CONCLUSIONS: TCZ is safe and decreases inflammation in PWH; IL-6 is a key driver of the inflammatory environment that predicts morbidity and mortality in ART-treated PWH. The clinical significance of lipid elevations during TCZ treatment requires further study. Clinical Trials Registration. NCT02049437.

The impact of COVID-19 on cardiovascular health behaviors in people living with HIV.

The COVID-19 pandemic's impact on cardiovascular health behaviors including diet, physical activity, medication adherence, and self-care among people living with HIV (PLWH) remains unknown. Using qualitative analyses, we examined the impact of the COVID-19 pandemic on cardiovascular health behaviors among PLWH. Twenty-four PLWH were enrolled in this multisite study from September to October 2020. Individuals participated in semi-structured telephone interviews that were recorded, transcribed, and coded by 4 independent coders. Codes were adjudicated and analyzed for common themes. Participants were, on average, 59.2 years old (+/-9.4), 75% African American (n = 18) and 71% male (n = 17). The pandemic altered cardiovascular disease health behaviors. PLWH changed diet based on stay-at-home orders and food access. Alterations in physical activity included transitioning from gym and group class exercise to home-based exercise. Antiretroviral adherence was maintained, even when other health behaviors wavered, suggesting resilience in PLWH that may be harnessed to maintain other health behaviors.

Psychological distress and health perception in patients with a previous myocardial infarction or stroke: a national cross-sectional study.

BACKGROUND: While understanding the impact of mental health on health perception improves patient-centered care, this relationship is not well-established in patients with cardiovascular disease (CVD). We examined the relationship between psychological distress and health perception in patients with a previous myocardial infarction (MI) and/or stroke. METHODS: We extracted data for patients with a previous MI and/or stroke from the 2019 National Health Interview Survey (NHIS). Health perception was self-reported. Presence and severity of anxiety and depression were estimated using the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-8 (PHQ-8). Binary analyses of anxiety/depression, multivariable logistic regressions controlling for confounders, and univariable analyses of confounders and anxiety/depression severity were performed. RESULTS: Of 31,948 individuals for whom data on MI/stroke was available, 1235 reported a previous MI and 1203 a previous stroke. The odds of positive perceived health status were lower for individuals with anxiety/depression compared to those without anxiety/depression in both post-MI (anxiety OR 0.52, 95% CI = 0.32-0.85, P < 0.001; depression OR 0.45, 95% CI = 0.29-0.7, P < 0.001) and post-stroke groups (anxiety OR 0.61, 95% CI = 0.39-0.97, P < 0.001; depression OR 0.37, 95% CI = 0.25-0.55, P < 0.001) upon multivariable analyses. Increasing severity of anxiety/depression was also associated with worse perception of health status upon univariable analysis. CONCLUSION: Among patients with a previous acute CVD event, those with psychological distress have worse perception of their health status. Understanding the range of patient health perceptions can help physicians provide more patient-centered care and encourage patient behaviors that may improve both CVD and mental health outcomes.

Use of Human-Centered Design Methodology to Develop a Digital Toolkit to Optimize Heart Failure Guideline-Directed Medical Therapy.

BACKGROUND: Guideline-directed medical therapies (GDMTs) improve quality of life and health outcomes for patients with heart failure (HF). However, GDMT utilization is suboptimal among patients with HF. OBJECTIVE: The aims of this study were to engage key stakeholders in semistructured, virtual human-centered design sessions to identify challenges in GDMT optimization posthospitalization and inform the development of a digital toolkit aimed at optimizing HF GDMTs. METHODS: For the human-centered design sessions, we recruited (a) clinicians who care for patients with HF across 3 hospital systems, (b) patients with HF with reduced ejection fraction (ejection fraction ≤ 40%) discharged from the hospital within 30 days of enrollment, and (c) caregivers. All participants were 18 years or older, English speaking, with Internet access. RESULTS: A total of 10 clinicians (median age, 37 years [interquartile range, 35-41], 12 years [interquartile range, 10-14] of experience caring for patients with HF, 80% women, 50% White, 50% nurse practitioners) and three patients and one caregiver (median age 57 years [IQR: 53-60], 75% men, 50% Black, 75% married) were included. Five themes emerged from the clinician sessions on challenges to GDMT optimization (eg, barriers to patient buy-in). Six themes on challenges (eg, managing medications), 4 themes on motivators (eg, regaining independence), and 3 themes on facilitators (eg, social support) to HF management arose from the patient and caregiver sessions. CONCLUSIONS: The clinician, patient, and caregiver insights identified through human-centered design will inform a digital toolkit aimed at optimizing HF GDMTs, including a patient-facing smartphone application and clinician dashboard. This digital toolkit will be evaluated in a multicenter, clinical trial.

Clinical Outcomes, Echocardiographic Findings, and Care Quality Metrics for People Living With Human Immunodeficiency Virus (HIV) and Rheumatic Heart Disease in Uganda.

BACKGROUND: Rheumatic heart disease (RHD) affects 41 million people worldwide, mostly in low- and middle-income countries, where it is co-endemic with human immunodeficiency virus (HIV). HIV is also a chronic inflammatory disorder associated with cardiovascular complications, yet the epidemiology of patients affected by both diseases is poorly understood. METHODS: Utilizing the Uganda National RHD Registry, we described the echocardiographic findings, clinical characteristics, medication prescription rates, and outcomes of all 73 people carrying concurrent diagnoses of HIV and RHD between 2009 and 2018. These individuals were compared to an age- and sex-matched cohort of 365 subjects with RHD only. RESULTS: The median age of the HIV-RHD group was 36 years (interquartile range [IQR] 15), and 86% were women. The HIV-RHD cohort had higher rates of prior stroke/transient ischemic attack (12% vs 5%, P = .02) than the RHD-only group, with this association persisting following multivariable adjustment (odds ratio [OR] 3.08, P = .03). Prevalence of other comorbidities, echocardiographic findings, prophylactic penicillin prescription rates, retention in clinical care, and mortality were similar between the 2 groups. CONCLUSIONS: Patients living with RHD and HIV in Uganda are a relatively young, predominantly female group. Although RHD-HIV comorbid individuals have higher rates of stroke, their similar all-cause mortality and RHD care quality metrics (such as retention in care) compared to those with RHD alone suggest rheumatic heart disease defines their clinical outcome more than HIV does. We believe this study to be one of the first reports of the epidemiologic profile and longitudinal outcomes of patients who carry diagnoses of both conditions.

Perspectives of HIV specialists and cardiologists on the specialty referral process for people living with HIV: a qualitative descriptive study.

BACKGROUND: Cardiology care may be beneficial for risk factor management in people living with HIV (PLWH), yet limited information is available about the referral process from the perspectives of HIV specialists and cardiologists. METHODS: We conducted 28 qualitative interviews at academic medical centers in the United States from December 2019 to February 2020 using components of the Specialty Referral Process Framework: referral decision, entry into referral care, and care integration. We analyzed the data using applied thematic analysis. RESULTS: Reasons for cardiology referral most commonly included secondary prevention, uncontrolled risk factors, cardiac symptoms, and medication management. Facilitators in the referral process included ease of referral, personal relationships between HIV specialists and cardiologists, and close proximity of the clinic to the patient's home. Barriers included lack of transportation, transportation costs, insurance coverage gaps, stigma, and patient reluctance. CONCLUSIONS: Our results will inform future studies on implementation strategies aimed at improving the specialty referral process for PLWH.

Improved hypertension control at six months using an adapted WHO HEARTS-based implementation strategy at a large urban HIV clinic in Uganda.

OBJECTIVES: To adapt a World Health Organization HEARTS-based implementation strategy for hypertension (HTN) control at a large urban HIV clinic in Uganda and determine six-month HTN and HIV outcomes among a cohort of adult persons living with HIV (PLHIV). METHODS: Our implementation strategy included six elements: health education, medication adherence, and lifestyle counseling; routine HTN screening; task shifting of HTN treatment; evidence-based HTN treatment protocol; consistent supply of HTN medicines free to patients; and inclusion of HTN-specific monitoring and evaluation tools. We conducted a pre-post study from October 2019 to March 2020 to determine the effect of this strategy on HTN and HIV outcomes at baseline and six months. Our cohort comprised adult PLHIV diagnosed with HTN who made at least one clinic visit within two months prior to study onset. FINDINGS: We enrolled 1,015 hypertensive PLHIV. The mean age was 50.1 ± 9.5 years and 62.6% were female. HTN outcomes improved between baseline and six months: mean systolic BP (154.3 ± 20.0 to 132.3 ± 13.8 mmHg, p < 0.001); mean diastolic BP (97.7 ± 13.1 to 85.3 ± 9.5 mmHg, p < 0.001) and proportion of patients with controlled HTN (9.3% to 74.1%, p < 0.001). The HTN care cascade also improved: treatment initiation (13.4% to 100%), retention in care (16.2% to 98.5%), monitoring (16.2% to 98.5%), and BP control among those initiated on HTN treatment (2.2% to 75.2%). HIV cascade steps remained high (> 95% at baseline and six months) and viral suppression was unchanged (98.7% to 99.2%, p = 0.712). Taking ART for more than two years and HIV viral suppression were independent predictors of HTN control at six months. CONCLUSIONS: A HEARTS-based implementation strategy at a large, urban HIV center facilitates integration of HTN and HIV care and improves HTN outcomes while sustaining HIV control. Further implementation research is needed to study HTN/HIV integration in varied clinical settings among diverse populations.

Comparison of diet, muscle strength, steps per day and symptoms in people with HIV and HIV-negative peers.

People with HIV (PWH) experience a high frequency of symptoms that are associated with poor clinical outcomes. We conducted a secondary analysis of data from an observational study to examine whether diet, muscle strength, or physical activity were associated with symptoms among PWH and their HIV-uninfected peers. One-hundred ninety-one individuals (105 PWH and 86 HIV uninfected) with similar age and race were included. Symptoms were examined using the Patient-Reported Outcomes Measurement Information System (PROMIS-29) questionnaire, for which lower scores indicate higher function or fewer symptoms. The total healthy eating index score and carbohydrates, sugar sweet beverages, alcohol, and fiber consumption per day were obtained through 24-hour dietary recalls. A dynamometer was used to determine muscle strength. Steps per day were examined through 7 days of actigraphy. Linear regression analyses were used to determine the relationship between symptoms and diet, muscle strength, and steps per day. Participants were, on average, 54 years, 83% were African American, and 58% were male. In PWH, less healthy eating, fiber intake, and muscle strength were associated with poorer physical function; more steps per day were associated with fatigue; less daily carbohydrate consumption was associated with more pain. HIV-uninfected individuals demonstrated an association between fewer steps per day and poorer physical function and more pain, and less carbohydrate intake and more sleep disturbance. The relationships between diet, muscle strength, steps per day and PROMIS-29 health domains differed by HIV status.

The American Heart Association's Call to Action for Reducing the Global Burden of Rheumatic Heart Disease: A Policy Statement From the American Heart Association.

Rheumatic heart disease (RHD) affects ≈40 million people and claims nearly 300 000 lives each year. The historic passing of a World Health Assembly resolution on RHD in 2018 now mandates a coordinated global response. The American Heart Association is committed to serving as a global champion and leader in RHD care and prevention. Here, we pledge support in 5 key areas: (1) professional healthcare worker education and training, (2) technical support for the implementation of evidence-based strategies for rheumatic fever/RHD prevention, (3) access to essential medications and technologies, (4) research, and (5) advocacy to increase global awareness, resources, and capacity for RHD control. In bolstering the efforts of the American Heart Association to combat RHD, we hope to inspire others to collaborate, communicate, and contribute.

Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association.

BACKGROUND: The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS: The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals. RESULTS: Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS: The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Latent Tuberculosis Infection and Subclinical Coronary Atherosclerosis in Peru and Uganda.

BACKGROUND: Tuberculosis (TB) has been linked to an increased risk of atherosclerotic cardiovascular disease (ASCVD). We assessed whether latent TB infection (LTBI) is associated with subclinical coronary atherosclerosis in 2 TB-prevalent areas. METHODS: We analyzed cross-sectional data from studies conducted in Lima, Peru, and Kampala, Uganda. Individuals ≥40 years old were included. We excluded persons with known history of ASCVD events or active TB. Participants underwent QuantiFERON-TB (QFT) testing to define LTBI and computed tomography angiography to examine coronary atherosclerosis. A Coronary Artery Disease-Reporting Data System (CAD-RADS) score ≥3 defined obstructive CAD (plaque causing ≥50% stenosis). RESULTS: 113 and 91 persons with and without LTBI, respectively, were included. There were no significant differences between LTBI and non-LTBI participants in terms of age (median [interquartile range]; 56 [51-62] vs 55 [49-64] years; P = .829), male sex (38% vs 42%; P = .519), or 10-year ASCVD risk scores (7.1 [3.2-11.7] vs 6.1 [2.8-1.8]; P = .533). CAD prevalence (any plaque) was similar between groups (29% vs 24%; P = .421). Obstructive CAD was present in 9% of LTBI and 3% of non-LTBI individuals (P = .095). LTBI was associated with obstructive CAD after adjusting for ASCVD risk score, HIV status, and study site (adjusted OR, 4.96; 95% CI, 1.05-23.44; P = .043). Quantitative QFT TB antigen minus Nil interferon-γ responses were associated with obstructive CAD (adjusted OR, 1.2; 95% CI, 1.03-1.41; P = .022). CONCLUSIONS: LTBI was independently associated with an increased likelihood of subclinical obstructive CAD. Our data indicate that LTBI is a nontraditional correlate of ASCVD risk.

Characteristics, Prevention, and Management of Cardiovascular Disease in People Living With HIV: A Scientific Statement From the American Heart Association.

As early and effective antiretroviral therapy has become more widespread, HIV has transitioned from a progressive, fatal disease to a chronic, manageable disease marked by elevated risk of chronic comorbid diseases, including cardiovascular diseases (CVDs). Rates of myocardial infarction, heart failure, stroke, and other CVD manifestations, including pulmonary hypertension and sudden cardiac death, are significantly higher for people living with HIV than for uninfected control subjects, even in the setting of HIV viral suppression with effective antiretroviral therapy. These elevated risks generally persist after demographic and clinical risk factors are accounted for and may be partly attributed to chronic inflammation and immune dysregulation. Data on long-term CVD outcomes in HIV are limited by the relatively recent epidemiological transition of HIV to a chronic disease. Therefore, our understanding of CVD pathogenesis, prevention, and treatment in HIV relies on large observational studies, randomized controlled trials of HIV therapies that are underpowered to detect CVD end points, and small interventional studies examining surrogate CVD end points. The purpose of this document is to provide a thorough review of the existing evidence on HIV-associated CVD, in particular atherosclerotic CVD (including myocardial infarction and stroke) and heart failure, as well as pragmatic recommendations on how to approach CVD prevention and treatment in HIV in the absence of large-scale randomized controlled trial data. This statement is intended for clinicians caring for people with HIV, individuals living with HIV, and clinical and translational researchers interested in HIV-associated CVD.

Subclinical Vascular Disease in Children With Human Immunodeficiency Virus in Uganda Is Associated With Intestinal Barrier Dysfunction.

BACKGROUND: The risk of cardiovascular disease (CVD) and its mechanisms in children living with perinatally acquired HIV (PHIV) in sub-Saharan Africa has been understudied. METHODS: Mean common carotid artery intima-media thickness (IMT) and pulse-wave velocity (PWV) were evaluated in 101 PHIV and 96 HIV-negative (HIV-) children. PHIV were on ART, with HIV-1 RNA levels ≤400 copies/mL. We measured plasma and cellular markers of monocyte activation, T-cell activation, oxidized lipids, and gut integrity. RESULTS: Overall median (interquartile range, Q1-Q3) age was 13 (11-15) years and 52% were females. Groups were similar by age, sex, and BMI. Median ART duration was 10 (8-11) years. PHIV had higher waist-hip ratio, triglycerides, and insulin resistance (P ≤ .03). Median IMT was slightly thicker in PHIVs than HIV- children (1.05 vs 1.02 mm for mean IMT and 1.25 vs 1.21 mm for max IMT; P < .05), while PWV did not differ between groups (P = .06). In univariate analyses, lower BMI and oxidized LDL, and higher waist-hip ratio, hsCRP, and zonulin correlated with thicker IMT in PHIV (P ≤ .05). After adjustment for age, BMI, sex, CD4 cell count, triglycerides, and separately adding sCD163, sCD14, and hsCRP, higher levels of intestinal permeability as measured by zonulin remained associated with IMT (ß = 0.03 and 0.02, respectively; P ≤ .03). CONCLUSIONS: Our study shows that African PHIV have evidence of CVD risk and structural vascular changes despite viral suppression. Intestinal intestinal barrier dysfunction may be involved in the pathogenesis of subclinical vascular disease in this population.

The influence of healthcare financing on cardiovascular disease prevention in people living with HIV.

BACKGROUND: People living with HIV are diagnosed with age-related chronic health conditions, including cardiovascular disease, at higher than expected rates. Medical management of these chronic health conditions frequently occur in HIV specialty clinics by providers trained in general internal medicine, family medicine, or infectious disease. In recent years, changes in the healthcare financing for people living with HIV in the U.S. has been dynamic due to changes in the Affordable Care Act. There is little evidence examining how healthcare financing characteristics shape primary and secondary cardiovascular disease prevention among people living with HIV. Our objective was to examine the perspectives of people living with HIV and their healthcare providers on how healthcare financing influences cardiovascular disease prevention. METHODS: As part of the EXTRA-CVD study, we conducted in-depth, semi-structured interviews with 51 people living with HIV and 34 multidisciplinary healthcare providers and at three U.S. HIV clinics in Ohio and North Carolina from October 2018 to March 2019. Thematic analysis using Template Analysis techniques was used to examine healthcare financing barriers and enablers of cardiovascular disease prevention in people living with HIV. RESULTS: Three themes emerged across sites and disciplines (1): healthcare payers substantially shape preventative cardiovascular care in HIV clinics (2); physician compensation tied to relative value units disincentivizes cardiovascular disease prevention efforts by HIV providers; and (3) grant-based services enable tailored cardiovascular disease prevention, but sustainability is limited by sponsor priorities. CONCLUSIONS: With HIV now a chronic disease, there is a growing need for HIV-specific cardiovascular disease prevention; however, healthcare financing complicates effective delivery of this preventative care. It is important to understand the effects of evolving payer models on patient and healthcare provider behavior. Additional systematic investigation of these models will help HIV specialty clinics implement cardiovascular disease prevention within a dynamic reimbursement landscape.

Global Burden of Atherosclerotic Cardiovascular Disease in People Living With HIV: Systematic Review and Meta-Analysis.

BACKGROUND: With advances in antiretroviral therapy, most deaths in people with HIV are now attributable to noncommunicable illnesses, especially cardiovascular disease. We determine the association between HIV and cardiovascular disease, and estimate the national, regional, and global burden of cardiovascular disease attributable to HIV. METHODS: We conducted a systematic review across 5 databases from inception to August 2016 for longitudinal studies of cardiovascular disease in HIV infection. A random-effects meta-analysis across 80 studies was used to derive the pooled rate and risk of cardiovascular disease in people living with HIV. We then estimated the temporal changes in the population-attributable fraction and disability-adjusted life-years (DALYs) from HIV-associated cardiovascular disease from 1990 to 2015 at a regional and global level. National cardiovascular DALYs associated with HIV for 2015 were derived for 154 of the 193 United Nations member states. The main outcome measure was the pooled estimate of the rate and risk of cardiovascular disease in people living with HIV and the national, regional, and global estimates of DALYs from cardiovascular disease associated with HIV. RESULTS: In 793 635 people living with HIV and a total follow-up of 3.5 million person-years, the crude rate of cardiovascular disease was 61.8 (95% CI, 45.8-83.4) per 10 000 person-years. In comparison with individuals without HIV, the risk ratio for cardiovascular disease was 2.16 (95% CI, 1.68-2.77). Over the past 26 years, the global population-attributable fraction from cardiovascular disease attributable to HIV increased from 0.36% (95% CI, 0.21%-0.56%) to 0.92% (95% CI, 0.55%-1.41%), and DALYs increased from 0.74 (95% CI, 0.44-1.16) to 2.57 (95% CI, 1.53-3.92) million. There was marked regional variation with most DALYs lost in sub-Saharan Africa (0.87 million, 95% CI, 0.43-1.70) and the Asia Pacific (0.39 million, 95% CI, 0.23-0.62) regions. The highest population-attributable fraction and burden were observed in Swaziland, Botswana, and Lesotho. CONCLUSIONS: People living with HIV are twice as likely to develop cardiovascular disease. The global burden of HIV-associated cardiovascular disease has tripled over the past 2 decades and is now responsible for 2.6 million DALYs per annum with the greatest impact in sub-Saharan Africa and the Asia Pacific regions.

Rationale and design of a nurse-led intervention to extend the HIV treatment cascade for cardiovascular disease prevention trial (EXTRA-CVD).

Persons living with human immunodeficiency virus (PLHIV) are at increased risk of atherosclerotic cardiovascular disease (ASCVD). In spite of this, uptake of evidence-based clinical interventions for ASCVD risk reduction in the HIV clinic setting is sub-optimal. METHODS: EXTRA-CVD is a 12-month randomized clinical effectiveness trial that will assess the efficacy of a multi-component nurse-led intervention in reducing ASCVD risk among PLHIV. Three hundred high ASCVD risk PLHIV across three sites will be randomized 1:1 to usual care with generic prevention education or the study intervention. The study intervention will consist of four evidence-based components: (1) nurse-led care coordination, (2) nurse-managed medication protocols and adherence support (3) home BP monitoring, and (4) electronic health records support tools. The primary outcome will be change in systolic blood pressure and secondary outcome will be change in non-HDL cholesterol over the course of the intervention. Tertiary outcomes will include change in the proportion of participants in the following extended cascade categories: (1) appropriately diagnosed with hypertension and hyperlipidemia (2) appropriately managed; (3) at treatment goal (systolic blood pressure <130 mm Hg and non-HDL cholesterol < National Lipid Association targets). CONCLUSIONS: The EXTRA-CVD trial will provide evidence appraising the potential impact of nurse-led interventions in reducing ASCVD risk among PLHIV, an essential extension of the HIV care continuum beyond HIV viral suppression.

Trends and presentation patterns of acute rheumatic fever hospitalisations in the United States.

OBJECTIVE: Rheumatic fever, an immune sequela of untreated streptococcal infections, is an important contributor to global cardiovascular disease. The goal of this study was to describe trends, characteristics, and cost burden of children discharged from hospitals with a diagnosis of RF from 2000 to 2012 within the United States. METHODS: Using the Kids' Inpatient Database, we examined characteristics of children discharged from hospitals with the diagnosis of rheumatic fever over time including: overall hospitalisation rates, age, gender, race/ethnicity, regional differences, payer type, length of stay, and charges. RESULTS: The estimated national cumulative incidence of rheumatic fever in the United States between 2000 and 2012 was 0.61 cases per 100,000 children. The median age was 10 years, with hospitalisations significantly more common among children aged 6-11 years. Rheumatic fever hospitalisations among Asian/Pacific Islanders were significantly over-represented. The proportion of rheumatic fever hospitalisations was greater in the Northeast and less in the South, although the highest number of rheumatic fever admissions occurred in the South. Expected payer type was more likely to be private insurance, and the median total hospital charges (adjusted for inflation to 2012 dollars) were $16,000 (interquartile range: $8900-31,200). Median length of stay was 3 days, and the case fatality ratio for RF in the United States was 0.4%. CONCLUSIONS: Rheumatic fever persists in the United States with an overall downwards trend between 2003 and 2012. Rheumatic fever admissions varied considerably based on age group, region, and origin.
