RESUMEN

BACKGROUND: Palliative care (PC) is an essential component of high-quality care for people with cardiovascular disease (CVD). However, little is known about the current state of PC education in CVD training, including attitudes toward integration of PC into training and implementation of PC by the program's leadership. METHODS: We developed a nationwide, cross-sectional survey that queried education approaches, perspectives and barriers to PC education in general CVD fellowship training. The survey was distributed to 392 members of the American College of Cardiology Program Director (PD) listserv, representing 290 general CVD fellowships between 1/2023 and 4/2023. We performed descriptive and ꭕ2 analyses of survey data. RESULTS: Of the program's representatives, 56 completed the survey (response rate = 19.3%). Respondents identified themselves as current PDs (89%), associate PDs (8.9%) or former PDs (1.8%), representing a diverse range of program sizes and types and regions of the country. Respondents reported the use of informal bedside teaching (88%), formal didactics (59%), online or self-paced modules (13%), in-person simulation (11%), and clinical rotations (16%) to teach PC content. Most programs covered PC topics at least annually, although there was variability by topic. We found no associations between program demographics and type or frequency of PC education. Most respondents reported dissatisfaction with the quantity (62%) or quality (59%) of the PC education provided. Barriers to PC education included an overabundance of other content to cover (36%) and perceived lack of fellow (20%) or faculty (18%) interest. Comments demonstrated the importance of PC education in fellowship, the lack of a requirement to provide PC education, difficulty in covering all topics, and suggestions of how PC skills should be taught. CONCLUSIONS: In a national survey of CVD educational leadership concerning approaches to PC education in CVD training, respondents highlighted both challenges to implementation of formal PC curricula in cardiology training and opportunities for comprehensive PC education.

RESUMEN

BACKGROUND: Low-middle-income countries face an enormous burden of tobacco-related illnesses. Counseling for tobacco cessation increases the chance of achieving quit outcomes, yet it remains underutilized in healthcare settings. OBJECTIVE: We tested the hypothesis that utilizing trained medical students to counsel hospitalized patients who use tobacco will lead to an increase in patient quit rates, while also improving medical student knowledge regarding smoking cessation counseling. DESIGN: Investigator-initiated, two-armed, multicenter randomized controlled trial conducted in three medical schools in India. PARTICIPANTS: Eligibility criteria included age 18-70 years, active admission to the hospital, and current smoking. INTERVENTION: A medical student-guided smoking cessation program, initiated in hospitalized patients and continued for 2 months after discharge. MAIN MEASURES: The primary outcome was self-reported 7-day point prevalence of smoking cessation at 6 months. Changes in medical student knowledge were assessed using a pre- and post-questionnaire delivered prior to and 12 months after training. KEY RESULTS: Among 688 patients randomized across three medical schools, 343 were assigned to the intervention group and 345 to the control group. After 6 months of follow up, the primary outcome occurred in 188 patients (54.8%) in the intervention group, and 145 patients (42.0%) in the control group (absolute difference, 12.8%; relative risk, 1.67; 95% confidence interval, 1.24-2.26; p < 0.001). Among 70 medical students for whom data was available, knowledge increased from a mean score of 14.8 (± 0.8) (out of a maximum score of 25) at baseline to a score of 18.1 (± 0.8) at 12 months, an absolute mean difference of 3.3 (95% CI, 2.3-4.3; p < 0.001). CONCLUSIONS: Medical students can be trained to effectively provide smoking cessation counseling to hospitalized patients. Incorporating this program into the medical curriculum can provide experiential training to medical students while improving patient quit rates. TRIAL REGISTRATION: URL: http://www.

RESUMEN

BACKGROUND: Health literacy has predicted mortality in heart failure. However, the role of cognitive functioning in this relationship has not been evaluated. We hypothesized that health literacy would predict all-cause mortality but that cognitive functioning would modify the relationship between health literacy and mortality in heart failure. OBJECTIVE: The aim of this study was to examine the association between health literacy, cognitive functioning, and mortality in patients with heart failure. METHODS: This secondary analysis of a larger study included 298 patients with heart failure with reduced ejection fraction (trial identifier: NCT01461629). Health literacy was evaluated using the Rapid Estimate of Adult Literacy in Medicine (REALM) and Medical Term Recognition Test (METER), and cognitive functioning was evaluated using the Modified Mini-Mental Status Examination (3MS). Cox proportional hazards regression was used with time-until-death as the dependent variable. RESULTS: After controlling for age, sex, and race, neither METER nor REALM scores predicted mortality in heart failure (Ps ≥ .37). However, 3MS predicted mortality in models using the METER (Δχ2 = 9.20, P < .01; B = -.07; hazard ratio, 0.94 [95% confidence interval, 0.89-0.98]; P < .01) and REALM (Δχ2 = 9.77, P < .01; B = -0.07; hazard ratio, 0.94 [95% confidence interval, 0.90-0.97]; P < .01). Furthermore, adding the 3MS improved model fit. CONCLUSIONS: Cognitive functioning predicted mortality in heart failure better than health literacy. Results suggest the need to further evaluate the contribution of cognitive functioning to increased risk of mortality in those with heart failure.

RESUMEN

Fatigue and depressive symptoms are prevalent and associated with poor clinical outcomes, though the underlying physiological mechanisms of fatigue and depression are poorly understood. We examined the impact of cardiorespiratory fitness (CRF) on fatigue and depressive symptoms in one-hundred and nine PLHIV. CRF was examined by maximal cardiorespiratory stress test and determined by peak oxygen uptake. Patient-reported fatigue was examined utilizing the HIV-Related Fatigue Scale. Depressive symptoms were examined with the Beck Depression Inventory and PROMISE 29. Data was collected at baseline and six months. Generalized estimating equations were used to determine the effect of CRF on fatigue and depressive symptoms over time. Participants were approximately 53 years old, 86% African American (n = 93), and 65% male (n = 70). After controlling for age and sex, fatigue was inversely associated with CRF (ß = -0.163; p = .005). Depressive symptoms were not associated with CRF as measured by the BeckDepression Inventory (p = .587) nor PROMIS 29 (p = .290), but over time, depressive symptoms decreased (p = .051). Increased CRF was associated with decreased fatigue levels, but was not associated with depressive symptoms. These results should guide future research aimed at how CRF might inform interventions to improve fatigue in PLHIV.

RESUMEN

BACKGROUND: Living arrangements, social support, and self-efficacy have significant implications for self-management science. Despite the theoretical linkages among the 3 concepts, there is limited empirical evidence about their interplay and the subsequent influence on heart failure (HF) self-management. OBJECTIVE: The aim of this study was to validate components of the Individual and Family Self-management Theory among individuals with HF. METHODS: This is a secondary analysis of cross-sectional data generated from a sample of 370 individuals with HF. A path analysis was conducted to examine the indirect and direct associations among social environment (living arrangements), social facilitation (social support) and belief (self-efficacy) processes, and self-management behaviors (HF self-care maintenance) while accounting for individual and condition-specific factors (age, sex, race, and HF disease severity). RESULTS: Three contextual factors (living arrangements, age, and HF disease severity) had direct associations with perceived social support and self-efficacy, which in turn were positively associated with HF self-management behaviors. Living alone (ß = -.164, P = .001) was associated with lower perceived social support, whereas being an older person (ß = .145, P = .004) was associated with better support. Moderate to severe HF status (ß = -.145, P = .004) or higher levels of perceived social support (ß = .153, P = .003) were associated with self-efficacy. CONCLUSIONS: Our results support the Individual and Family Self-management Theory, highlighting the importance of social support and self-efficacy to foster self-management behaviors for individuals with HF. Future research is needed to further explore relationships among living arrangements, perceived and received social support, self-efficacy, and HF self-management.

RESUMEN

BACKGROUND: Exercise is a common recommendation to reduce the risk factors of metabolic syndrome, yet there are limited data on the influence of lifestyle exercise after cardiac events on metabolic syndrome factors. OBJECTIVE: The purpose of this study was to determine whether lifestyle exercise improves metabolic syndrome profile in older adults after a cardiac event. METHODS: Participants were from a post-cardiac-event lifestyle exercise study. Five metabolic syndrome factors were assessed: waist circumference, triglycerides, high-density lipids, glucose, and systolic and diastolic blood pressure. Objective measures of exercise were obtained from heart rate monitors over a year. Logistic regression was used to determine whether participants who engaged in the minimum recommendation of 130 hours of exercise or greater during the 12-month period improved their metabolic syndrome profile by improving at least 1 metabolic syndrome factor. RESULTS: In the sample of 116 participants (74% men; average age, 67.5 years), 43% exercised at the recommended amount (≥130 h/y) and 28% (n = 33) improved their metabolic syndrome profile. After controlling for confounding factors of age, gender, race, diabetes, functional ability, and employment, subjects who exercised at least 130 hours a year were 3.6 times more likely to improve at least 1 metabolic syndrome factor (95% confidence interval, 1.24-10.49). Of the 28% who improved their metabolic syndrome profile, 72% increased their high-density lipoprotein and 60.6% reduced their waist circumference and glucose. CONCLUSIONS: After a cardiac event, older patients who engage in lifestyle exercise at the recommended amount have improvement in their metabolic syndrome profile.

RESUMEN

BACKGROUND: Lifestyle physical activity (ie, moderate physical activity during routine daily activities most days of the week) may benefit human immunodeficiency virus (HIV)-positive adults who are at high risk for cardiovascular disease. OBJECTIVE: The aims of this study were to describe lifestyle physical activity patterns in HIV-positive adults and to examine the influence of lifestyle physical activity on markers of cardiovascular health. Our secondary objective was to compare these relationships between HIV-positive adults and well-matched HIV-uninfected adults. METHODS: A total of 109 HIV-positive adults and 20 control participants wore an ActiGraph accelerometer, completed a maximal graded cardiopulmonary exercise test, completed a coronary computed tomography, completed anthropomorphic measures, and had lipids and measures of insulin resistance measured from peripheral blood. RESULTS: Participants (N = 129) had a mean age of 52 ± 7.3 years, 64% were male (n = 82), and 88% were African American (n = 112). On average, HIV-positive participants engaged in 33 minutes of moderate-to-vigorous physical activity per day (interquartile range, 17-55 minutes) compared with 48 minutes in controls (interquartile range, 30-62 minutes, P = .05). Human immunodeficiency virus-positive adults had poor fitness (peak oxygen uptake [VO2], 16.8 ± 5.2 mL/min per kg; and a ventilatory efficiency, 33.1 [4.6]). A marker of HIV disease (current CD4+ T cell) was associated with reduced peak VO2 (r = -0.20, P < .05) and increased insulin resistance (r = 0.25, P < .01) but not with physical activity or other markers of cardiovascular health (P ≥ 0.05). After controlling for age, gender, body mass index, and HIV status, physical activity was not significantly associated with peak VO2 or ventilatory efficiency. CONCLUSION: Human immunodeficiency virus-positive adults have poor physical activity patterns and diminished cardiovascular health. Future longitudinal studies should examine whether HIV infection blunts the beneficial effects of physical activity on cardiovascular health.

RESUMEN

Allergic reactions to contrast media are a frequently reported complication of coronary angiography. The majority of patients experience mild, self-limited episodes, but in rare cases patients may experience severe, persistent symptoms. A strategy of premedication with corticosteroids and anti-histamines and an optimal selection of contrast agent is almost always successful in averting contrast reactions, yet a select few patients will continue to have breakthrough events. This is a case of recurrent, severe allergy to contrast media despite standard precautions complicating the treatment of non-ST elevation myocardial infarction (NSTEMI). Our patient was successfully managed with a strategy of rapid desensitization to iodinated contrast media achieved by administering progressively incremental doses of the media.

RESUMEN

BACKGROUND: The increasing burden of cardiovascular disease (CVD) in low- and middle-income countries is largely driven by the increasing prevalence of hypertension, diabetes, and tobacco use. We hypothesize that the utilization of community health workers (CHWs) to screen for and manage these 3 determinants of CVD in an integrated manner would be an effective approach to favorably affecting public health. METHODS: We have designed and set up the infrastructure to implement a 2-year community-based cluster randomized controlled trial in an underserved region of West Bengal, India. Participants include around 1200 adults, aged between 35 and 70 years, with ≥1 cardiovascular risk factor. They are recruited through home-based screening into a total of 12 clusters, which are randomized to either a control or intervention arm before screening. After the screening, CHWs follow up with participants enrolled in the intervention arm for a period of 2 years through home visits. The control arm receives usual care in the community. The CHW arm follows a behavioral strategy focused on modifying the individual's lifestyle, increasing knowledge of CVD, promoting smoking cessation, increasing physician-seeking behavior, and promoting medication adherence. The main project office is based in Cleveland, OH, at University Hospitals/CWRU, and the local site office is located in Dalkhola, West Bengal, at a local nonprofit set up for the study. Institutional review board approval was obtained both in Cleveland as well as in India. OUTCOME EVALUATION: The 2-year primary outcome of the study is the absolute reduction in systolic blood pressure among hypertensive participants, absolute reduction in fasting blood glucose among diabetic participants, and absolute reduction in average number of cigarettes smoked per day among smokers. DISCUSSION: We believe that this study infrastructure serves as a useful model for international collaboration. It builds on unique local resources, attends to important domestic requirements, and will ultimately provide an evidence-based approach that will help manage the increasing burden of CVD worldwide.

RESUMEN

Granulomatosis with polyangiitis (GPA) is a rare vasculitis that can have multisystem involvement, though cardiac involvement is very rare. The case is described of a 53-year-old woman who presented with acute aortic and mitral valve regurgitation requiring surgical intervention. Pathology from the excised aortic valve showed geographic necrosis concerning for GPA. Subsequent rheumatologic testing was positive for anti-serine proteinase 3 (PR3) antibody, consistent with GPA. A year after the valve surgery the patient was found to have a vegetation of the mitral valve and elevated PR3 antibody levels, and was successfully treated with an intensification of immunosuppression. The cardiac involvement of GPA is discussed and big data analyzed to identify the epidemiology of valvular involvement. In conclusion, GPA can have multiple different valvular manifestations with a high recurrence rate. GPA should be considered in patients who present with acute valvular disease without any clear precipitant.

RESUMEN

Patients with heart failure (HF) take many medications to manage their HF and comorbidities, and 20-50% experience depression. Depressed individuals with more complex medication regimens may be at greater risk for poor adherence. The aim of this study was to assess depressive symptoms as a moderator of the relationship between medication regimen complexity and medication adherence in an observational study of patients with HF. In hierarchical linear regression with the final sample of 299, the interaction of medication regimen complexity and depressive symptoms predicted medication adherence, p < .05. For individuals with higher levels of depressive symptoms [1 standard deviation (SD) above the mean], more regimen complexity was associated with lower adherence. For individuals with low (1 SD below the mean) or average levels of depressive symptoms, regimen complexity was unrelated to medication adherence. Care management strategies, including pillboxes and caregiver involvement, may be valuable in HF patients with depression.

RESUMEN

BACKGROUND: Cognitive deficits are found in up to 73% of persons with heart failure (HF) and are associated with increased mortality and other poor clinical outcomes. It is known that women have better memory test performance than men do in healthy samples, but gender differences in cognitive performance in the context of HF are not well understood and may have important clinical implications. OBJECTIVE: The objective of this study was to examine possible gender differences in cognitive function in a sample of individuals with HF (98.9% New York Heart Association class II and III). METHODS: A total of 183 adults with HF (116 men and 67 women) completed a neuropsychological test battery as part of a larger project. Measures were chosen to assess functioning in attention/executive function and memory. RESULTS: After controlling for demographic and medical factors, multivariate analysis of covariance revealed that men and women differed on memory test performance (λ = 0.90, F4, 169 = 4.76, P = .001). Post hoc comparisons revealed that women performed better on California Verbal Learning Test Learning, Short Recall, and Delayed Recall. No differences emerged on tests of attention/executive function (λ = 0.97, F5, 168 = 0.96, P = .44). CONCLUSIONS: In this sample of persons with HF, men exhibited poorer performance on memory measures than women did. Future studies are needed to determine the underlying mechanisms for this pattern and its possible influence on daily function.

RESUMEN

BACKGROUND: Few investigators have examined whether cognitive deficits predict poorer self-care of weight management recommendations and weight gain in adults with heart failure. OBJECTIVE: The purposes of this study were (1) to examine whether cognition is associated with adherence to daily weighing and weight gain incidence and (2) to explore self-reported symptom perception and management when a weight increase occurs. METHODS: In this observational study, participants completed neuropsychological testing, were given an electronic scale, and were instructed to record their weight for 21 days. Data for 301 participants were collected at baseline and 3 weeks after weight monitoring. RESULTS: At baseline, only 35% of the enrolled respondents knew when to call their physician for increased weight gain, and 37% of the analyzed sample (n = 110/301) experienced a clinically significant weight gain. Regressions tested whether baseline attention, executive function, or memory predicted adherence to daily weighing and the likelihood of weight gain incidence. In unadjusted and adjusted covariate analyses, none of the cognitive domains predicted adherence to daily weighing (P ≥ .375); however, all 3 cognitive domains predicted an increased risk of a clinically significant weight gain (P ≤ .05). Importantly, 65% of participants with a weight gain did not identify this symptom on self-report questions. CONCLUSIONS: Although cognitive deficits are not associated with adherence to daily weighing, adults with cognitive deficits may be at an increased risk for experiencing a clinically significant weight gain, and most do not perceive symptoms. CLINICAL IMPLICATIONS: Adults with heart failure require more than directions on self-care related to weight monitoring.

RESUMEN

Historically, the relationship between exercise and the cardiovascular system was viewed as unidirectional, with a disease resulting in exercise limitation and hazard. This article reviews and explores the bidirectional nature, delineating the effects, generally positive, on the cardiovascular system and atherosclerosis. Exercise augments eNOS, affects redox potential, and favorably affects mediators of atherosclerosis including lipids, glucose homeostasis, and inflammation. There are direct effects on the vasculature as well as indirect benefits related to exercise-induced changes in body composition and skeletal muscle. Application of aerobic exercise to specific populations is described, with the hope that this knowledge will move the science forward and improve individual patient outcome.

RESUMEN

Cardiac rehabilitation (CR) has proven morbidity and mortality benefits in cardiovascular disease, which directly correlates with exercise performance achieved. Many patients in CR exercise at sub-optimal levels, without obvious limitations. Occult lower-extremity peripheral artery disease (PAD) may be a determinant of diminished exercise capacity and reduced benefit obtained from traditional CR. In this prospective study of 150 consecutive patients enrolled in Phase II CR, we describe the prevalence of PAD, the utility of externally validated screening questionnaires, and the observed impact on CR outcomes. Abnormal ankle-brachial indices (ABI) (< 0.9 and >1.4) were observed in 19% of those studied. The Edinburgh Claudication Questionnaire was insensitive for detecting PAD by low ABI in this population, and the Walking Impairment Questionnaire and a modified Gardner protocol demonstrated a lack of typical symptoms with low levels of activity. Importantly, at completion of traditional CR, exercise improvement measured in metabolic equivalents (METs) was worse in those with a low ABI compared to those with a normal ABI (+1.39 vs +2.41 METs, p = 0.002). In conclusion, PAD is common in patients in Phase II CR and often clinically occult. Screening based on standard questionnaires appears insensitive in this population, suggesting a need for a broad-based screening strategy with ABI measurements. In this study, undiagnosed PAD significantly attenuated improvements in exercise performance, which potentially has bearings on future clinical events.

RESUMEN

Anticoagulation is important in stroke prevention in patients with atrial fibrillation. Until recently, heparins and vitamin K antagonists were the only available therapy for stroke reduction in atrial fibrillation (AF) patients. Non-vitamin K antagonist oral anticoagulants (NOACs) including direct thrombin inhibitor (dabigatran) and direct factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) are now available and offer new options for stroke prevention. This article reviews the available data on the use of NOACs for primary and secondary stroke prevention in AF patients and describes specific patient populations to guide clinician in making the informed decision regarding appropriate use of those agents. It also addresses the use of NOACs early after acute stroke and use of thrombolysis while on NOAC.

RESUMEN

BACKGROUND: Heart failure patients require assistance with instrumental activities of daily living in part because of the high rates of cognitive impairment in this population. Structural brain insult (eg, reduced gray matter volume) is theorized to underlie cognitive dysfunction in heart failure, although no study has examined the association among gray matter, cognition, and instrumental activities of daily living in heart failure. OBJECTIVES: The aim of this study was to investigate the associations among gray matter volume, cognitive function, and functional ability in heart failure. METHODS: A total of 81 heart failure patients completed a cognitive test battery and the Lawton-Brody self-report questionnaire to assess instrumental activities of daily living. Participants underwent magnetic resonance imaging to quantify total gray matter and subcortical gray matter volume. RESULTS: Impairments in instrumental activities of daily living were common in this sample of HF patients. Regression analyses controlling for demographic and medical confounders showed that smaller total gray matter volume predicted decreased scores on the instrumental activities of daily living composite, with specific associations noted for medication management and independence in driving. Interaction analyses showed that reduced total gray matter volume interacted with worse attention/executive function and memory to negatively impact instrumental activities of daily living. CONCLUSIONS: Smaller gray matter volume is associated with greater impairment in instrumental activities of daily living in persons with heart failure, possibly via cognitive dysfunction. Prospective studies are needed to clarify the utility of clinical correlates of gray matter volume (eg, cognitive dysfunction) in identifying heart failure patients at risk for functional decline and determine whether interventions that target improved brain and cognitive function can preserve functional independence in this high-risk population.
