AIM: The "2023 AHA/ACC/ACCP/ASPC/NLA/PCNA Guideline for the Management of Patients With Chronic Coronary Disease" provides an update to and consolidates new evidence since the "2012 ACCF/AHA/ACP/AATS/PCNA/SCAI/STS Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease" and the corresponding "2014 ACC/AHA/AATS/PCNA/SCAI/STS Focused Update of the Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease." METHODS: A comprehensive literature search was conducted from September 2021 to May 2022. Clinical studies, systematic reviews and meta-analyses, and other evidence conducted on human participants were identified that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. STRUCTURE: This guideline provides an evidenced-based and patient-centered approach to management of patients with chronic coronary disease, considering social determinants of health and incorporating the principles of shared decision-making and team-based care. Relevant topics include general approaches to treatment decisions, guideline-directed management and therapy to reduce symptoms and future cardiovascular events, decision-making pertaining to revascularization in patients with chronic coronary disease, recommendations for management in special populations, patient follow-up and monitoring, evidence gaps, and areas in need of future research. Where applicable, and based on availability of cost-effectiveness data, cost-value recommendations are also provided for clinicians. Many recommendations from previously published guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Age-Stratified Sex Differences in Heart Failure With Preserved Ejection Fraction Among Adult Hospitalizations.

BACKGROUND: There is evidence that heart failure with preserved ejection fraction (HFpEF)-related hospitalizations are increasing in the United States. However, there is a lack of knowledge about HFpEF-related hospitalizations among younger adults. OBJECTIVE: The aims of this study were to perform a retrospective analysis using the Nationwide Inpatient Sample and to examine age-stratified sex differences in the prevalence, correlates, and outcomes of HFpEF-related hospitalization across the adult life span. METHOD: Using the Nationwide Inpatient Sample (2002-2014), patient and hospital characteristics were determined. Joinpoint regression was used to describe age-stratified sex differences in the annual average percent change of hospitalizations with HFpEF. Survey logistic regression was used to estimate adjusted odds ratios representing the association of sex with HFpEF-related hospitalization and in-hospital mortality. RESULTS: There were 8 599 717 HFpEF-related hospitalizations (2.43% of all hospitalizations). Women represented the majority (5 459 422 [63.48%]) of HFpEF-related adult hospitalizations, compared with men (3 140 295 [36.52%]). Compared with men younger than 50 years, women within the same age group were 6% to 28% less likely to experience HFpEF-related hospitalization. Comorbidities such as hypertensive heart disease, renal disease, hypertension, obstructive sleep apnea, atrial fibrillation, obesity, anemia, and pulmonary edema explained a greater proportion of the risk of HFpEF-related hospitalization in adults younger than 50 years than in adults 50 years or older. CONCLUSION: Before the age of 50 years, women exhibit lower HFpEF-related hospitalization than men, a pattern that reverses with advancing age. Understanding and addressing the factors contributing to these sex-specific differences can have several potential implications for improving women's cardiovascular health.

Pregnancy-associated takotsubo cardiomyopathy hospitalizations in the United States.

Takotsubo cardiomyopathy (TCM) is most common not only in postmenopausal women aged ≥50 yr but also in pregnant individuals. However, there are no national estimates on the prevalence, timing of occurrence, correlates, and outcomes of pregnancy-associated TCM. Using the Nationwide Inpatient Sample (NIS: 2016-2020), we describe rates of pregnancy-associated TCM hospitalizations among 13- to 49-yr-old pregnant individuals in the United States by selected demographic, behavioral, hospital, and clinical characteristics. Joinpoint regression was used to describe the annual average percent change of pregnancy-associated TCM hospitalizations. Survey logistic regression was used to measure the association of pregnancy-associated TCM hospitalizations with maternal outcomes. Of the 19,754,535 pregnancy-associated hospitalizations, 590 were TCM associated. The overall trend in pregnancy-associated TCM hospitalizations remained stable during the study period. The majority of TCM occurred during the postpartum, followed by antepartum and delivery-associated hospitalizations. When compared with pregnancy hospitalizations without TCM, those with TCM were more likely to be over the age of 35 yr and use tobacco and opioids. Comorbidities during TCM-associated pregnancy hospitalizations included heart failure, coronary artery disease, hemorrhagic stroke, and hypertension. After controlling for potential confounders, the odds of pregnancy-associated TCM hospitalizations were 98.7 times [adjusted odds ratio (aOR) = 98.66, 95% confidence interval (CI) 31.23-311.64] and 14.7 times (aOR = 14.75, 95% CI 9.99-21.76) higher for experiencing in-hospital mortality and a prolonged hospital stay, respectively, than those without TCM. Although rare, pregnancy-associated TCM hospitalization is more likely to occur during the postpartum period and is associated with in-hospital mortality and prolonged hospital stay.NEW & NOTEWORTHY Although rare, pregnancy-associated takotsubo cardiomyopathy hospitalizations are more likely to occur during the postpartum period and are associated with in-hospital mortality and prolonged hospital stay.

Use of Marijuana: Effect on Brain Health: A Scientific Statement From the American Heart Association.

Marijuana is perceived as a harmless drug, and its recreational use has gained popularity among young individuals. The concentration of active ingredients in recreational formulations has gradually increased over time, and high-potency illicit cannabinomimetics have become available. Thus, the consumption of cannabis in the general population is rising. Data from preclinical models demonstrate that cannabinoid receptors are expressed in high density in areas involved in cognition and behavior, particularly during periods of active neurodevelopment and maturation. In addition, growing evidence highlights the role of endogenous cannabinoid pathways in the regulation of neurotransmitter release, synaptic plasticity, and neurodevelopment. In animal models, exogenous cannabinoids disrupt these important processes and lead to cognitive and behavioral abnormalities. These data correlate with the higher risk of cognitive impairment reported in some observational studies done in humans. It is unclear whether the effect of cannabis on cognition reverts after abstinence. However, this evidence, along with the increased risk of stroke reported in marijuana users, raises concerns about its potential long-term effects on cognitive function. This scientific statement reviews the safety of cannabis use from the perspective of brain health, describes mechanistically how cannabis may cause cognitive dysfunction, and advocates for a more informed health care worker and consumer about the potential for cannabis to adversely affect the brain.

A Mother-Child Dyadic Approach to Evaluating Subclinical Cardiovascular Disease in Young Children: A Feasibility Study.

BACKGROUND: Cardiovascular (CV) risk factors can be transmitted from mothers to their children. However, it is challenging to measure and identify subclinical CV risk in young children using traditional CV risk methods and metrics. OBJECTIVE: The purpose of this study was to determine the feasibility of recruiting mother-child dyads and measuring arterial stiffness (pulse wave velocity, augmentation index/pressure), blood pressure (BP), BP circadian pattern, specifically nocturnal BP dipping, and CV health metrics in mothers and in children aged 1 to 5 years. METHODS: All BP and arterial stiffness measures were obtained using the noninvasive automated oscillometric Mobil-O-Graph device. Also measured were blood cholesterol level; glucose level; body mass index (BMI); and smoking, diet, and physical activity history. Descriptive statistics were used for assessing recruitment feasibility and Pearson correlations for mother-child associations. RESULTS: Thirty-five mother-child dyads completed the protocol. Recruitment reach was 89% and retention rate was 80%. Mothers were 34.3 ± 5.4 years old with a mean systolic BP (SBP) of 114.6 ± 9.5 mm Hg and BMI of 26.0 ± 6.5. Children were 3 ± 1.4 years old with a mean SBP of 103.3 ± 9.4 mm Hg and BMI z-scores of -0.3 ± 1.5. Arterial stiffness parameters were within normal ranges for mothers and children. Twenty-three percent of mothers did not exhibit nocturnal dipping (<10% decrease between day and nighttime SBP). Maternal SBP was positively correlated with child BMI z-scores (r = 0.42, P = .022) as well as mother-child augmentation pressure (r = 0.51, P = .010). CONCLUSIONS: Our findings support using a mother-child approach and novel noninvasive approaches to assess and target CV risk in mothers and their young children.

Assessing postgraduate outcomes of research-intensive nursing science PhD programs: Methods and metrics.

BACKGROUND: Across disciplines and within higher educational systems, assessing postgraduate outcomes is essential for evaluating doctoral programs, including research-intensive nursing science doctoral programs. However, there are limited reports regarding methods and metrics related to postgraduate longitudinal evaluation of research-focused nursing doctoral programs. PURPOSE: The purpose of this paper is to summarize studies in the area of postgraduate outcome assessment and provide recommendations regarding outcome methods and metrics for evaluating the effectiveness of research-focused nursing doctoral programs. METHODS: PubMed/Medline, CINHAL Complete, and Google Scholar databases were searched using key words including PhD program, doctoral program, longitudinal evaluation, evaluation, program evaluation, PhD alumni survey, education outcomes and PhD program outcomes. We excluded non-English and full-text articles that were not available for review. DISCUSSION: Based on a review of the literature, there are few reports on methods and questionnaires for postgraduate outcome assessment. There is a critical need to develop standardized core metrics/questions, longitudinal assessments, and a shared data repository. The latter will allow for comparisons across nursing doctoral programs. CONCLUSION: Robust standardized longitudinal assessment of nursing doctoral programs is a necessary step for comparison across programs and re-envisioning the nursing doctoral education of the future.

Medical Marijuana, Recreational Cannabis, and Cardiovascular Health: A Scientific Statement From the American Heart Association.

Cannabis, or marijuana, has potential therapeutic and medicinal properties related to multiple compounds, particularly Δ-9-tetrahydrocannabinol and cannabidiol. Over the past 25 years, attitudes toward cannabis have evolved rapidly, with expanding legalization of medical and recreational use at the state level in the United States and recreational use nationally in Canada and Uruguay. As a result, the consumption of cannabis products is increasing considerably, particularly among youth. Our understanding of the safety and efficacy of cannabis has been limited by decades of worldwide illegality and continues to be limited in the United States by the ongoing classification of cannabis as a Schedule 1 controlled substance. These shifts in cannabis use require clinicians to understand conflicting laws, health implications, and therapeutic possibilities. Cannabis may have therapeutic benefits, but few are cardiovascular in nature. Conversely, many of the concerning health implications of cannabis include cardiovascular diseases, although they may be mediated by mechanisms of delivery. This statement critically reviews the use of medicinal and recreational cannabis from a clinical but also a policy and public health perspective by evaluating its safety and efficacy profile, particularly in relationship to cardiovascular health.

Pregnancy Associated Heart Failure With Preserved Ejection Fraction: Risk Factors and Maternal Morbidity.

BACKGROUND: Cardiovascular conditions are leading contributors to increasing maternal morbidity and mortality. Heart failure with preserved ejection fraction (HFpEF) results in the majority of HF admissions in women, yet its impact in pregnancy is unknown. We examined the prevalence rates, risk factors and adverse pregnancy outcomes in women with HFpEF during pregnancy-related hospitalizations in the United States. METHODS AND RESULTS: We conducted a cross-sectional analysis of pregnancy-related hospitalizations from 2002 through 2014 using the National Inpatient Sample. HFpEF cases were identified using the 428.3 International Classification of Diseases, 9th edition, Clinical Modification code. Weighting variables were used to provide national estimates, unconditional survey logistic regression to generate odds ratios and 95% confidence intervals (CI) representing adjusted associations with adverse pregnancy outcomes and Joinpoint regression to estimate temporal trends. Among 58,732,977 hospitalizations, there were 3840 HFpEF cases, an overall rate of 7 cases per 100,000 pregnancy-related hospitalizations; 56% occurred postpartum, 27% during delivery, and 17% antepartum. The temporal trend for hospitalization increased throughout the timeframe by 19.4% (95% CI 13.9-25.1). HFpEF hospitalizations were more common for Black, older, or poor women. Risk factors included hypertension (chronic hypertension and hypertensive disorders of pregnancy), anemia, obesity, diabetes, renal disease and coronary atherosclerosis; all known risk factors for HFpEF. Women with HFpEF were 2.61-6.47 times more likely to experience adverse pregnancy outcomes. CONCLUSIONS: The pregnancy-related HFpEF hospitalization prevalence has increased and is associated with adverse pregnancy outcomes. Risk factors resemble those outside pregnancy, emphasizing the need for screening and monitoring women with risk factors during pregnancy for HFpEF.

Factors associated with phosphatidylethanol (PEth) sensitivity for detecting unhealthy alcohol use: An individual patient data meta-analysis.

BACKGROUND: Objective measurement of alcohol consumption is important for clinical care and research. Adjusting for self-reported alcohol use, we conducted an individual participant data (IPD) meta-analysis to examine factors associated with the sensitivity of phosphatidylethanol (PEth), an alcohol metabolite, among persons self-reporting unhealthy alcohol consumption. METHODS: We identified 21 eligible studies and obtained 4073 observations from 3085 participants with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) positive scores (≥3 for women and ≥4 for men) and PEth measurements. We conducted 1-step IPD meta-analysis using mixed effects models with random intercepts for study site. We examined the associations between demographic (sex, race/ethnicity, and age) and biologic (body mass index-BMI, hemoglobin, HIV status, liver fibrosis, and venous versus finger-prick blood collection) variables with PEth sensitivity (PEth≥8 ng/ml), adjusting for the level of self-reported alcohol use using the AUDIT-C score. RESULTS: One third (31%) of participants were women, 32% were African, 28% African American, 28% White, and 12% other race/ethnicity. PEth sensitivity (i.e., ≥8 ng/ml) was 81.8%. After adjusting for AUDIT-C, we found no associations of sex, age, race/ethnicity, or method of blood collection with PEth sensitivity. In models that additionally included biologic variables, those with higher hemoglobin and indeterminate and advanced liver fibrosis had significantly higher odds of PEth sensitivity; those with higher BMI and those living with HIV had significantly lower odds of PEth sensitivity. African Americans and Africans had higher odds of PEth sensitivity than whites in models that included biologic variables. CONCLUSIONS: Among people reporting unhealthy alcohol use, several biological factors (hemoglobin, BMI, liver fibrosis, and HIV status) were associated with PEth sensitivity. Race/ethnicity was associated with PEth sensitivity in some models but age, sex, and method of blood collection were not. Clinicians should be aware of these factors, and researchers should consider adjusting analyses for these characteristics where possible.

Tetrahydrobiopterin Restores Microvascular Dysfunction in Young Adult Binge Drinkers.

BACKGROUND: Repeated binge drinking is associated with reduced microvascular function. However, microvascular responses to pathophysiological stimulus such as high pressure as well as potential mechanisms that underlie binge-induced microvascular dysfunction are unknown. Therefore, using an ex vivo experimental model, we examined microvascular responses following a brief period of high intraluminal pressure in isolated arterioles from young adults who have a history of repeated binge drinking. In addition, we examined whether the application of the endothelial nitric oxide synthase cofactor, tetrahydrobiopterin, would restore microvascular function in response to flow and high intraluminal pressure in young adult binge drinkers. METHODS: Isolated subcutaneous adipose arterioles were obtained from young adult binge drinkers (BD; n = 14), moderate drinkers (MODs; n = 10), and alcohol abstainers (ABs; n = 12; mean age: 23.7 ± 0.5 years; and body mass index: 23.4 ± 0.4 kg/m2 ). Arteriolar flow-induced dilation (FID, pressure gradient: ∆10 to 100 cm H2 O) was measured before and after acute high intraluminal pressure with and without tetrahydrobiopterin. RESULTS: Before high pressure, FID at Δ60 and Δ100 cm H2 O pressure gradient in BDs was 14% lower and 18% lower, respectively, than ABs (p < 0.05), while MODs and ABs had similar FID across all pressure gradients (p ≥ 0.2). After high pressure, FID in BDs was further reduced by 10% (p < 0.0005) and this impairment was ameliorated by the treatment of tetrahydrobiopterin (4 to 26% higher, p < 0.005). In contrast, FID after high pressure did not change in MODs and ABs (p ≥ 0.5). CONCLUSIONS: Microvascular dysfunction in young adult binge drinkers may be exacerbated with acute pathophysiological stimulus. These binge-induced dysfunctions may be reversed by tetrahydrobiopterin, which suggests a role of oxidative stress and/or uncoupled endothelial nitric oxide synthase in binge drinking.

Relationship between cardiovascular risk factors and binge drinking among college students in South Korea.

This study determined cardiovascular risk among Korean college students with a history of binge drinking. Variables included alcohol consumption, cardiovascular risk factors (increased blood pressure, body mass index, lipid values) and markers (high-sensitivity C-reactive protein, fibrinogen), and 10-year Framingham risk scores. Korean college student binge drinkers had higher triglyceride levels and higher ratios of triglyceride to high-density lipoprotein cholesterol than did abstainers. Average number of drinks on one occasion was correlated with higher body mass index, triglyceride level, ratio of triglyceride to high-density lipoprotein cholesterol, and 10-year Framingham risk score. The findings indicate that binge drinking may be associated with premature cardiovascular disease risk.

Contemporary Appraisal of Sex Differences in Prevalence, Correlates, and Outcomes of Alcoholic Cardiomyopathy.

AIMS: The aims of this study were to: examine differences in alcoholic cardiomyopathy (ACM) prevalence, temporal trends and the distribution of socio-demographic factors and comorbidities by sex; and investigate differences in selected inpatient outcomes between women and men with ACM. METHODS: We used the 2002-2014 Nationwide Inpatient Sample databases. Overall and sex-specific rates of ACM were estimated across sociodemographic, clinical, and hospital characteristics. Joinpoint regression was used to estimate temporal trends (annual percent change [APC]) of ACM-related hospitalization by sex and race/ethnicity. Adjusted odds ratios (AOR) representing associations between sex and selected ACM outcomes were calculated using survey logistic regression. RESULTS: The rate of ACM among all inpatient men and women was 128 per 100,000 and 17 per 100,000 hospitalizations, respectively. Among women, the rate of ACM remained unchanged during the study period, while for men, there was 1.2% annual reduction from 2002-2010 (APC -1.3, 95% CI: -1.7, -0.8). Women with ACM were more likely than men with ACM to experience depression (AOR=2.24, 95% CI: 2.06-2.43) and anxiety (AOR=1.94, 95% CI: 1.75-2.15), while men with ACM were 21% and 24% more likely than women with ACM to experience 'any heart failure (HF)' and HF with reduced ejection fraction respectively. One in 1,471 hospitalizations were related to ACM with a male-to-female ratio of 8:1. CONCLUSION: Individuals with ACM are at increased likelihood of adverse outcomes. Women with ACM are at increased risk of depression and anxiety, while men are at increased risk of HF.

Perceived Stress Among Patients With Heart Failure Who Have Low Socioeconomic Status: A Mixed-Methods Study.

BACKGROUND: Patient populations with low socioeconomic status (SES) experience psychological stress because of social determinants of health. Social determinants of health contribute to self-care-especially among patients with heart failure (HF). OBJECTIVE: We sought to describe the influence of stress and social determinants of health on self-care in patients with HF who have low SES. METHODS: In this mixed-methods, concurrent embedded study, participants (N = 35) were recruited from 2 urban hospitals in Chicago if they had low SES and were readmitted within 120 days of an exacerbation of HF. We conducted semistructured interviews to collect qualitative data about stressors associated with patients' living circumstances, strategies patients used to foster self-care, family dynamics, and coping strategies patients used to decrease stress. We measured psychological stress (Perceived Stress Scale [PSS-10]), and self-care (Self-care of Heart Failure Index). Content analysis was used to analyze the qualitative data, and descriptive statistics were used to describe the sample. In the final analytic phase, the qualitative and quantitative data were integrated. RESULTS: Self-care was poor: 91.5% of participants had Self-care of Heart Failure Index subscale scores lower than 70. Perceived stress was high: 34% of participants had PSS-10 scores of 20 or higher. Several social determinants of health emerged as affecting self-care: financial stress, family personal health, past impactful deaths, and a recent stressful event (eg, child's death). Participants lived in areas with high crime and violence, and participants described many stressful events. However, among participants whose PSS-10 scores were lower than 20 (indicating lower stress), there was discordance among the description of factors impacting self-care and their PSS-10 score. CONCLUSIONS: Social determinants of health negatively impact the ability of low-SES patients to manage their HF symptoms and adhere to a medication and dietary regimen. It is important that healthcare providers assess patients' stressors so appropriate referral to services can occur.

MicroRNA-21 Contributes to Reduced Microvascular Function in Binge Drinking Young Adults.

BACKGROUND: Binge drinking is associated with increased risk for cardiovascular (CV) disease. MicroRNA-21 (miR21) is up-regulated in the setting of excessive alcohol consumption and CV disease. Therefore, the goal of this study was to examine the vasodilatory responses to flow and acetylcholine (ACh) in the absence and presence of an anti-miR21 inhibitor in the microcirculation of young adult repeated binge drinkers (BDs). METHODS: Gluteal subcutaneous adipose tissue biopsies were obtained from young adults (18 to 30 years, n = 35 vessels from BDs and n = 28 vessels from abstainers). Resistance arteries (RAs) were isolated, incubated with anti-miR21 or a negative control (NC) to miR21 (12 hours; 50 nM), and lumen diameters measured with video microscopy. miR21 of adipose tissues was determined by quantitative polymerase chain reaction. RESULTS: Flow-induced dilation and ACh-induced dilation (AChID) were reduced in BDs as compared to abstainers. The miR21 inhibitor but not the NC abrogated these effects in BDs, but did not affect vasodilation in abstainers. Nitric oxide synthase inhibition with L-NAME reduced vasodilation in abstainers but not in BDs. In BDs, vasodilation was reduced by L-NAME in the presence of anti-miR21 but not the NC. Scavenging the reactive oxygen species, hydrogen peroxide with polyethylene glycol catalase reduced dilation in BDs but did not affect the restored dilation by the miR21 inhibitor. Maximum dilation to papaverine (endothelium independent) was similar between groups and unaffected by pharmacological inhibition. Finally, vascular endogenous miR21 was increased in BDs compared to abstainers. CONCLUSIONS: Endogenous miR21 is increased in RAs of young BDs, leading to reduced flow and AChID in the microcirculation.

Cardiovascular Nursing Science Priorities: A Statement From the American Heart Association Council on Cardiovascular and Stroke Nursing.

BACKGROUND: The American Heart Association's (AHA) Council on Cardiovascular and Stroke Nursing (CVSN) plays a critical role in advancing the mission of the AHA in the discovery of new scientific knowledge. The aim was to identify priority research topics that would promote and improve cardiovascular (CV) health, provide direction for the education of future nurse scientists, and serve as a resource and catalyst for federal and organizational funding priorities. METHODS: A Qualtrics survey, which included 3 questions about priorities for CVSN nurse researchers, was sent to the CVSN Leadership Committee and all CVSN Fellows of the AHA (n = 208). Responses to the questions were reviewed for word repetitions, patterns, and concepts and were then organized into thematic areas. The thematic areas were reviewed within small groups at the November (2016) in-person CVSN leadership meeting. RESULTS: Seventy-three surveys were completed. Five thematic areas were identified and included (1) developing and testing interventions, (2) assessment and monitoring, (3) precision CV nursing care, (4) translational and implementation science, and (5) big data. Topic areas noted were stroke, research methods, prevention of stroke and CV disease, self-management, and care and health disparities. CONCLUSION: Five thematic areas and 24 topic areas were identified as priorities for CV nursing research. These findings can provide a guide for CV nurse scientists and for federal and foundational funders to use in developing funding initiatives. We believe additional research and discovery in these thematic areas will help reduce the rising global burden of CV disease.

Cardiovascular Consequences of Binge Drinking: An Integrative Review with Implications for Advocacy, Policy, and Research.

Worldwide, binge drinking is a major public health problem. The popularized health risks associated with binge drinking include physical injury and motor vehicle crashes; less attention has been given to the negative effects on the cardiovascular (CV) system. The primary aims of this review were to provide a summary of the adverse effects of binge drinking on the risk and development of CV disease and to review potential pathophysiologic mechanisms. Using specific inclusion criteria, an integrative review was conducted that included data from human experimental, prospective cross-sectional, and cohort epidemiological studies that examined the association between binge drinking and CV conditions such as hypertension (HTN), myocardial infarction (MI), stroke, and arrhythmias. Studies were identified that examined the relationship between binge drinking and CV outcomes. Collectively, findings support that binge drinking is associated with a higher risk of pre-HTN, HTN, MI, and stroke in middle-aged and older adults. Binge drinking may also have adverse CV effects in young adults (aged 18 to 30). Mechanisms remain incompletely understood; however, available evidence suggests that binge drinking may induce oxidative stress and vascular injury and be proatherogenic. Public health messages regarding binge drinking need to include the effects of binge drinking on the CV system.

Measurement of Dyspnea in Ambulatory African Americans With Heart Failure and a Preserved or Reduced Ejection Fraction.

BACKGROUND: Dyspnea is a burdensome and disabling heart failure (HF) symptom. Few studies examining dyspnea in HF have included African Americans (AAs), despite their developing HF at a younger age and having the highest mortality rates. OBJECTIVE: The purpose of this cross-sectional study was to examine dyspnea in AA patients with HF and a preserved ejection fraction (HFpEF) compared with those with a reduced ejection fraction (HFrEF), before and after the 6-minute walk test (6MWT). METHODS: A convenience sample of ambulatory AA patients (HFrEF, n = 26; HFpEF, n = 19) 50 years or older was recruited from an urban HF clinic. The Borg Scale and a visual analog scale (VAS) were used to measure dyspnea intensity before and after the 6MWT. Activity limitations related to dyspnea were described using the modified Medical Research Council Dyspnea Scale. Group comparisons were analyzed using repeated-measures analysis of variance and χ 2tests. Convergent validity was determined between the Borg and VAS using Bland-Altman plots. RESULTS: No significant differences were found in age, gender, and comorbidities between HF groups. Most HFpEF patients reported dyspnea at baseline (Borg, 63%; VAS, 73%) and after the 6MWT (Borg, 78%; VAS, 79%). In the HFrEF group, the prevalence of baseline dyspnea was greater when measured with the VAS (Borg, 34%; VAS, 80%) but was similar between instruments after the 6MWT (Borg, 64%; VAS, 77%). Both groups reported a similar change in dyspnea intensity during and after the 6MWT. The Bland-Altman plots indicated moderate agreement at each time point. Most patients described walking hurriedly or uphill as dyspnea-provoking on the Modified Respiratory Council Dyspnea Scale. CONCLUSIONS: The prevalence of dyspnea at baseline and after the 6MWT was high for both groups, but intensity varied with the dyspnea instrument used.
