PURPOSE: Cognitive impairment is a common consequence of stroke and has direct implications for poststroke functioning and quality of life, including the ability to maintain a job, live independently, sustain interpersonal relationships, and drive a vehicle. In this scientific statement, we critically appraise the literature on the prevalence, diagnosis, and management of poststroke cognitive impairment (PSCI) and provide a framework for clinical care while highlighting gaps that merit further study. METHODS: We performed a scoping literature review of randomized controlled clinical trials, prospective and retrospective cohort studies, case-control studies, clinical guidelines, review articles, and editorials on the incidence and prevalence, natural history, diagnosis, and management of PSCI. Scoping reviews determine the scope of a body of literature on a given topic to indicate the volume of literature and the studies currently available and provide an overview of its focus. RESULTS: PSCI is common after stroke, especially in the first year, and ranges from mild to severe. Although cognitive impairment is reversible in some cases early after stroke, up to one-third of individuals with stroke develop dementia within 5 years. The pathophysiology is not yet fully elucidated but is likely attributable to an acute stroke precipitating a series of pathological events, often in the setting of preexisting microvascular and neurodegenerative changes. Screening for associated comorbidities and interdisciplinary management are integral components of the care of individuals with PSCI. There is a need for prospective studies evaluating the individual trajectory of PSCI and the role of the acute vascular event in the predisposition for Alzheimer disease and related dementias, as well as high-quality, randomized clinical trials focused on PSCI management.

Nearly 500 000 individuals are treated with maintenance hemodialysis for kidney failure in the United States, and roughly half will die of cardiovascular causes. Hypertension, an important and modifiable risk factor for cardiovascular disease, is observed in >80% of patients treated with maintenance hemodialysis. The pathophysiology of hypertension in patients treated with maintenance hemodialysis is multifactorial and differs from that seen in other patient populations. Factors that contribute to hypertension in patients treated with hemodialysis include volume overload, arterial stiffness, enhanced activity of the sympathetic nervous and renin-angiotensin-aldosterone systems, endothelial dysfunction, and use of erythropoietin-stimulating agents. This scientific statement reviews the current evidence on defining, diagnosing, and treating hypertension in patients treated with maintenance hemodialysis and highlights opportunities for future investigation, including studies on blood pressure targets and treatment strategies.

BACKGROUND: The COVID-19 pandemic has evolved through multiple phases characterized by new viral variants, vaccine development, and changes in therapies. It is unknown whether rates of cardiovascular disease (CVD) risk factor profiles and complications have changed over time. METHODS: We analyzed the American Heart Association COVID-19 CVD registry, a national multicenter registry of hospitalized adults with active COVID-19 infection. The time period from April 2020 to December 2021 was divided into 3-month epochs, with March 2020 analyzed separately as a potential outlier. Participating centers varied over the study period. Trends in all-cause in-hospital mortality, CVD risk factors, and in-hospital CVD outcomes, including a composite primary outcome of cardiovascular death, cardiogenic shock, new heart failure, stroke, and myocardial infarction, were evaluated across time epochs. Risk-adjusted analyses were performed using generalized linear mixed-effects models. RESULTS: A total of 46 007 patient admissions from 134 hospitals were included (mean patient age 61.8 years, 53% male, 22% Black race). Patients admitted later in the pandemic were younger, more likely obese, and less likely to have existing CVD (Ptrend ≤0.001 for each). The incidence of the primary outcome increased from 7.0% in March 2020 to 9.8% in October to December 2021 (risk-adjusted Ptrend=0.006). This was driven by an increase in the diagnosis of myocardial infarction and stroke (Ptrend<0.0001 for each). The overall rate of in-hospital mortality was 14.2%, which declined over time (20.8% in March 2020 versus 10.8% in the last epoch; adjusted Ptrend<0.0001). When the analysis was restricted to July 2020 to December 2021, no temporal change in all-cause mortality was seen (adjusted Ptrend=0.63). CONCLUSIONS: Despite a shifting risk factor profile toward a younger population with lower rates of established CVD, the incidence of diagnosed cardiovascular complications of COVID increased from the onset of the pandemic through December 2021. All-cause mortality decreased during the initial months of the pandemic and thereafter remained consistently high through December 2021.

Cardiovascular disease is the leading cause of death in women, yet differences exist among certain racial and ethnic groups. Aside from traditional risk factors, behavioral and environmental factors and social determinants of health affect cardiovascular health and risk in women. Language barriers, discrimination, acculturation, and health care access disproportionately affect women of underrepresented races and ethnicities. These factors result in a higher prevalence of cardiovascular disease and significant challenges in the diagnosis and treatment of cardiovascular conditions. Culturally sensitive, peer-led community and health care professional education is a necessary step in the prevention of cardiovascular disease. Equitable access to evidence-based cardiovascular preventive health care should be available for all women regardless of race and ethnicity; however, these guidelines are not equally incorporated into clinical practice. This scientific statement reviews the current evidence on racial and ethnic differences in cardiovascular risk factors and current cardiovascular preventive therapies for women in the United States.

BACKGROUND: Preservation of brain health has emerged as a leading public health priority for the aging world population. Advances in neurovascular biology have revealed an intricate relationship among brain cells, meninges, and the hematic and lymphatic vasculature (the neurovasculome) that is highly relevant to the maintenance of cognitive function. In this scientific statement, a multidisciplinary team of experts examines these advances, assesses their relevance to brain health and disease, identifies knowledge gaps, and provides future directions. METHODS: Authors with relevant expertise were selected in accordance with the American Heart Association conflict-of-interest management policy. They were assigned topics pertaining to their areas of expertise, reviewed the literature, and summarized the available data. RESULTS: The neurovasculome, composed of extracranial, intracranial, and meningeal vessels, as well as lymphatics and associated cells, subserves critical homeostatic functions vital for brain health. These include delivering O2 and nutrients through blood flow and regulating immune trafficking, as well as clearing pathogenic proteins through perivascular spaces and dural lymphatics. Single-cell omics technologies have unveiled an unprecedented molecular heterogeneity in the cellular components of the neurovasculome and have identified novel reciprocal interactions with brain cells. The evidence suggests a previously unappreciated diversity of the pathogenic mechanisms by which disruption of the neurovasculome contributes to cognitive dysfunction in neurovascular and neurodegenerative diseases, providing new opportunities for the prevention, recognition, and treatment of these conditions. CONCLUSIONS: These advances shed new light on the symbiotic relationship between the brain and its vessels and promise to provide new diagnostic and therapeutic approaches for brain disorders associated with cognitive dysfunction.

BACKGROUND: Black men in the United States have higher hypertension (HTN) prevalence than other groups, largely due to adverse social determinants of health, including poor healthcare access. The Community-to-Clinic Linkage Implementation Program (CLIP) is effective for HTN screening in Black-owned barbershops. However, its effect on HTN prevention among Black men is untested. Here, we describe the rationale and study protocol for the development and testing of a barbershop facilitation (BF) strategy, with trained Community Health Workers, to implement and scale CLIP for HTN prevention in Black men. METHODS: The study is part of the American Heart Association (AHA)-funded RESTORE (Addressing Social Determinants to Prevent Hypertension) Health Equity Research Network. The study is tri-phasic: (i) pre-implementation-qualitative examination of factors affecting adoption of CLIP and development of BF strategy, (ii) implementation-cluster randomized control trial to test the effectiveness of CLIP with and without BF. We will partner with 20 barbershops and enroll 420 Black men with elevated blood pressure (BP)/Stage 1 HTN (2017 ACC/AHA HTN guidelines). Outcomes include reduction in BP, rate of CLIP adoption and linkage to care, and incidence of Stage 2 HTN. The study time frame is 12 months, (iii) post-implementation-we will evaluate program sustainability (6 months post-trial conclusion) and cost-effectiveness (up to 10 years). CONCLUSIONS: This study harnesses community-based resources to address HTN prevention in Black men, who are more adversely impacted by HTN than other groups. It has major policy relevance for health departments and other stakeholders to address HTN prevention in Black communities. CLINICALTRIALS.GOV IDENTIFIER: NCT05447962.

Background The American Heart Association defines ideal cardiovascular health based on 8 risk factors (Life's Essential 8 [LE8]); a high LE8 score (range 0-100) reflects greater adherence to their recommendations. Weight status influences cardiovascular health, yet individuals may use detrimental diet and weight loss strategies to improve weight status. We assessed differences in LE8 adherence, diet quality, and weight loss strategies between those with and without a recent history of clinically significant weight loss (CSWL). Methods and Results Data from 2007 to 2016 National Health and Nutrition Examination Survey questionnaires, clinical measures, and 24-hour dietary recalls were assessed to determine LE8 adherence, diet quality (Healthy Eating Index), and weight loss strategies between adults with: (1) intentional CSWL ≥5%; and (2) non-CSWL <5%, weight maintenance, or weight gain over the past 12 months using ANCOVA and chi-square tests. Those with CSWL demonstrated higher scores for diet quality (P=0.014), physical activity (P<0.001), and blood lipids (P<0.001). Those without CSWL reported lower BMI (P<0.001). There were no differences in total LE8 cardiovascular health scores between those with and without CSWL. More individuals with CSWL reported weight loss strategies of exercising (P=0.016); those without CSWL reported skipping meals (P=0.002) and using prescription diet pills (P<0.001). Conclusions Greater adherence to the LE8 recommendations was observed among individuals with CSWL, although overall LE8 scores were low. Future research should address the implementation of evidence-based strategies that improve diet quality while promoting optimal cardiovascular health among those with intent to lose weight.

BACKGROUND: While young adults 18-24 years old bear a significant proportion of COVID-19 diagnoses, the risk factors for hospitalisation and severe COVID-19 complications in this population are poorly understood. OBJECTIVE: The objective of this study was to identify risk factors for hospitalisation and other COVID-19 complications across the health spectrum of young adults diagnosed with COVID-19 infection. STUDY DESIGN: Retrospective cohort study. PARTICIPANTS: Young adults (aged 18-24) with confirmed COVID-19 infection from the American Heart Association (AHA) COVID-19 Cardiovascular Disease Registry of hospitalised patients and the Outcomes Registry for Cardiac Conditions in Athletes (ORCCA) study of collegiate athletes. The AHA registry included 636 young adults from 152 hospitals. The ORCCA registry consisted of 3653 competitive college athletes from 42 colleges and universities. INTERVENTION: None (exposure to COVID-19). PRIMARY AND SECONDARY OUTCOME MEASURES: Main outcomes included hospitalisation, death, major adverse cardiovascular events (MACE) and other severe clinical events. RESULTS: In comparison to the ORCCA registry, patients in the AHA registry were more likely to be female (59% vs 33%); had higher average body mass index (BMI) (32.4 vs 25.6); and had increased prevalence of diabetes (10% vs 0.4%), hypertension (7% vs 0.6%), chronic kidney disease (2% vs 0%) and asthma (14% vs 8%), all with p<0.01. There were eight (2%) deaths in the AHA hospitalised registry compared with zero in the ORCCA cohort. BMI was a statistically significant predictor of death in the hospitalised cohort (OR 1.05, 95% CI 1.00, 1.10). No significant predictors of MACE or other severe clinical events were identified. CONCLUSIONS: The risk of cardiac events in young adults aged 18-24 diagnosed with COVID-19 infection is low. Patients who were hospitalised (AHA registry) were more likely to have pre-existing medical comorbidities and higher BMI than healthy collegiate athletes (ORCCA registry). Once hospitalised, elevated BMI is associated with increased mortality although other drivers of MACE and other severe clinical events remain unclear.

The overall prevalence of hypertension in childhood is 2% to 5%, and the leading type of childhood hypertension is primary hypertension, especially in adolescence. As in adults, the leading risk factors for children with primary hypertension are excess adiposity and suboptimal lifestyles; however, environmental stress, low birth weight, and genetic factors may also be important. Hypertensive children are highly likely to become hypertensive adults and to have measurable target organ injury, particularly left ventricular hypertrophy and vascular stiffening. Ambulatory and home blood pressure monitoring may facilitate diagnosis. Primordial prevention of hypertension through public health implementation of healthier diet and increased physical activity will reduce the prevalence of primary hypertension, and evidence-based treatment guidelines should be implemented when hypertension is diagnosed. Further research to optimize recognition and diagnosis and clinical trials to better define outcomes of treatment are needed.

There is increasing interest in the long-term cardiovascular health of women with complicated pregnancies and their affected offspring. Emerging antenatal risk factors such as preeclampsia appear to increase the risk of hypertension and cardiovascular disease across the life course in both the offspring and women after pregnancy. However, the antenatal programming mechanisms responsible are complex and incompletely understood, with roots in alterations in the development, structure, and function of the kidney, heart, vasculature, and brain. The renin-angiotensin-aldosterone system is a major regulator of maternal-fetal health through the placental interface, as well as kidney and cardiovascular tissue development and function. Renin-angiotensin-aldosterone system dysregulation plays a critical role in the development of pregnancy complications such as preeclampsia and programming of long-term adverse cardiovascular health in both the mother and the offspring. An improved understanding of antenatal renin-angiotensin-aldosterone system programming is crucial to identify at-risk individuals and to facilitate development of novel therapies to prevent and treat disease across the life course. Given the inherent complexities of the renin-angiotensin-aldosterone system, it is imperative that preclinical and translational research studies adhere to best practices to accurately and rigorously measure components of the renin-angiotensin-aldosterone system. This comprehensive synthesis of preclinical and translational scientific evidence of the mechanistic role of the renin-angiotensin-aldosterone system in antenatal programming of hypertension and cardiovascular disease will help (1) to ensure that future research uses best research practices, (2) to identify pressing needs, and (3) to guide future investigations to maximize potential outcomes. This will facilitate more rapid and efficient translation to clinical care and improve health outcomes.

Heart failure with preserved ejection fraction (HFpEF) is one of the most common forms of heart failure; its prevalence is increasing, and outcomes are worsening. Affected patients often experience severe exertional dyspnea and debilitating fatigue, as well as poor quality of life, frequent hospitalizations, and a high mortality rate. Until recently, most pharmacological intervention trials for HFpEF yielded neutral primary outcomes. In contrast, trials of exercise-based interventions have consistently demonstrated large, significant, clinically meaningful improvements in symptoms, objectively determined exercise capacity, and usually quality of life. This success may be attributed, at least in part, to the pleiotropic effects of exercise, which may favorably affect the full range of abnormalities-peripheral vascular, skeletal muscle, and cardiovascular-that contribute to exercise intolerance in HFpEF. Accordingly, this scientific statement critically examines the currently available literature on the effects of exercise-based therapies for chronic stable HFpEF, potential mechanisms for improvement of exercise capacity and symptoms, and how these data compare with exercise therapy for other cardiovascular conditions. Specifically, data reviewed herein demonstrate a comparable or larger magnitude of improvement in exercise capacity from supervised exercise training in patients with chronic HFpEF compared with those with heart failure with reduced ejection fraction, although Medicare reimbursement is available only for the latter group. Finally, critical gaps in implementation of exercise-based therapies for patients with HFpEF, including exercise setting, training modalities, combinations with other strategies such as diet and medications, long-term adherence, incorporation of innovative and more accessible delivery methods, and management of recently hospitalized patients are highlighted to provide guidance for future research.

BACKGROUND AND AIMS: The American Heart Association proposed 7 ideal cardiovascular health metrics (Life's Simple 7 [LS7]) namely, not smoking, body mass index <25 kg/m2, healthy diet, moderate physical activity ≥150 min/week, total blood cholesterol <200 mg/dL, blood pressure <120/80 mmHg and fasting blood glucose <100 mg/dL. Our objective was to assess the association between these LS7 metrics and the incidence of atrial fibrillation (AF). METHODS AND RESULTS: A total of 6,479 participants of the PREDIMED study were included. We calculated the participants' baseline LS7 index ranging 0-7 points to categorize them according to their adherence to these LS7 health metrics. Multivariable Cox regression models were used to estimate Hazard Ratios (HR) and their 95% Confidence Intervals (95% CI). After a median follow-up of 4.8 years, we identified 250 incident cases of AF. After adjusting for potential confounders, adherence to LS7 index was not associated with the incidence of AF (adjusted HR 0.90 [95% CI: 0.56-1.45] for highest vs. lowest LS7 categories). Body mass index <25 kg/m2 was the only health metric individually associated with a lower risk of AF (HR 0.36 [95% CI: 0.16-0.78]). CONCLUSIONS: In a high cardiovascular risk Spanish population, adherence to American Heart Association's LS7 metrics was not associated with the risk of incident AF.

PURPOSE OF REVIEW: This is a pragmatic decision aid for initiating pharmacotherapy for stage 1 hypertension. RECENT FINDINGS: If a stage 1 patient presents with clinical signs of fluid retention, then a diuretic should be the primary agent. However, if the patient is normovolemic, then a vasodilator should be the primary agent. If targeted blood pressure is not achieved with the primary agent, then the choices are dose escalation or the addition of a second drug. For stage 1, the addition of secondary agents is preferred. This approach includes the polypill (a single pill with multiple low-dose antihypertensive agents). The positives are the polypill lessens the need to make decisions associated with up-titration and the low doses mitigate adverse side effects. The polypill targets several concurrent mechanisms to counteract hypertension. For stage 1, the goal should be to lower blood pressure with a simple regiment which minimizes adverse side affects.

The American Heart Association's Strategically Focused Children's Research Network started in July 2017 with 4 unique programs at Children's National Hospital in Washington, DC; Duke University in Durham, North Carolina; University of Utah in Salt Lake City, Utah; and Lurie Children's Hospital/Northwestern University in Chicago, Illinois. The overarching goal of the Children's National center was to develop evidence-based strategies to strengthen the health system response to rheumatic heart disease through synergistic basic, clinical, and population science research. The overall goals of the Duke center were to determine risk factors for obesity and response to treatment including those that might work on a larger scale in communities across the country. The integrating theme of the Utah center focused on leveraging big data-science approaches to improve the quality of care and outcomes for children with congenital heart defects, within the context of the patient and their family. The overarching hypothesis of the Northwestern center is that the early course of change in cardiovascular health, from birth onward, reflects factors that result in either subsequent development of cardiovascular risk or preservation of lifetime favorable cardiovascular health. All 4 centers exceeded the original goals of research productivity, fellow training, and collaboration. This article describes details of these accomplishments and highlights challenges, especially around the COVID-19 pandemic.
