Background: Arterial stiffness has been associated with an increased risk of cardiovascular disease (CVD) in some patient populations.

Objectives: The aims of this study were to investigate (1) whether there is an association between arterial stiffness, as measured by the Mobil-O-Graph, and risk for CVD in a population of individuals with intellectual disability and (2) whether arterial stiffness can predict the risk for CVD.

Methods: This cross-sectional study included 58 individuals who participated in wave 4 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Aging (2019-2020). Statistical models were used to address the first aim, whereas machine learning models were used to improve the accuracy of risk predictions in the second aim.

Results: Sample characteristics were mean (SD) age of 60.69 (10.48) years, women (62.1%), mild/moderate level of intellectual disability (91.4%), living in community group homes (53.4%), overweight/obese (84.5%), high cholesterol (46.6%), alcohol consumption (48.3%), hypertension (25.9%), diabetes (17.24%), and smokers (3.4%). Mean (SD) pulse wave velocity (arterial stiffness measured by Mobil-O-Graph) was 8.776 (1.6) m/s. Cardiovascular disease risk categories, calculated using SCORE2, were low-to-moderate risk (44.8%), high risk (46.6%), and very high risk (8.6%). Using proportional odds logistic regression, significant associations were found between arterial stiffness, diabetes diagnosis, and CVD risk SCORE2 ( P < .001). We also found the Mobil-O-Graph can predict risk of CVD, with prediction accuracy of the proportional odds logistic regression model approximately 60.12% (SE, 3.2%). Machine learning models, k -nearest neighbor, and random forest improved model predictions over and above proportional odds logistic regression at 75.85% and 77.7%, respectively.

Conclusions: Arterial stiffness, as measured by the noninvasive Mobil-O-Graph, can be used to predict risk of CVD in individuals with intellectual disabilities.

Background: The life expectancy of individuals with schizophrenia in the United States is 20% shorter than that of the general population owing to cardiovascular disease (CVD). It is crucial to identify the factors that reduce CVD risk in these individuals.

Objective: In this systematic review, we examined the factors associated with CVD in people with schizophrenia.

Methods: We searched 3 electronic databases for English articles published before April 2023. Investigators assessed the factors associated with 2 cardiovascular health outcomes among people with schizophrenia: the 10-year coronary heart disease (CHD)/CVD risk and peak oxygen uptake (VO 2Peak/max ).

Results: We retrieved 17 studies from the search. Investigators examined factors affecting 10-year CHD/CVD risk in 11 studies and VO 2Peak/max in 6 studies among people with schizophrenia. We found that individuals who had low metabolic symptoms (ie, hypertension and hyperglycemia), did not smoke, engaged in continuous CVD risk assessments, had a shorter duration of the diagnosis and hospitalization, and were of normal weight had a lower 10-year CHD/CVD risk. Furthermore, individuals who engaged in specific physical activity had a higher VO 2Peak/max . Finally, those taking antipsychotic medications had a higher 10-year CHD/CVD risk and a lower VO 2Peak/max .

Conclusions: The CVD risk factors observed in the general population are common among people with schizophrenia. When these risk factors are controlled, the 10-year CHD/CVD risk and VO 2Peak/max of these individuals may be improved. Given the elevated CVD risk associated with antipsychotic medications, future researchers should examine modifying CVD risk factors to mitigate the additional risks associated with medication use in this population.

Background: Informal caregivers contribute substantially to the self-care of people with heart failure (HF) by helping with concrete and interpersonal tasks. Time perception and management are essential issues among caregivers. However, investigators have not explored this topic in caregivers of people with HF.

Objectives: The aim of this study was to describe the perceptions and challenges of the time management experience among caregivers who support the self-care efforts of their relatives with HF.

Methods: Adult informal caregivers of patients with HF, taking care of the patient for at least 3 months and without cognitive limitations, were recruited from Spain, Italy, and the Netherlands. Data were collected using semistructured interviews. Maryring's qualitative content analysis strategy with both a deductive and an inductive approach was used for analysis.

Results: We enrolled 50 participants (20 Italians, 19 Spanish, and 11 Dutch). Caregivers had a mean (SD) age of 62.8 (12.8) years and were mostly female (84%). They dedicated 31.2 (SD, 21.7) hours per week to providing caring activities for their patients. After extracting 33 codes from their qualitative interview data, we summarized them into 8 categories and identified 4 main themes: (1) time for yourself, (2) house management, (3) time for the patient (dedicated to directing care), and (4) time for own socialization.

Conclusion: Caregivers navigate the complexity of time management by balancing dedicated time for supporting patients with HF and their own personal time.

Background: Many individuals with congenital heart disease (CHD) undergo open heart surgery, resulting in prominent scarring. However, little research has assessed the impact of surgical scarring on body image in this population.

Objective: Within this cross-sectional study, associations between body image concerns, anxiety and depression symptoms, and health-related quality of life among individuals with CHD were evaluated.

Methods: Young adults with CHD (N = 138) completed the Body Image Disturbance Questionnaire along with other patient-reported outcome measures.

Results: Scores on the Body Image Disturbance Questionnaire were lower (mean, 1.3 ± 0.5) than populations with diabetes amputations, craniofacial conditions, idiopathic scoliosis, and clinical controls. Higher Body Image Disturbance Questionnaire scores were reported among women ( P = .003) and were associated with greater anxiety ( P = .000) and depression ( P = .13) after controlling for sex.

Conclusions: Body image concerns related to cardiac surgery scarring are especially prominent in women and associated with greater emotional distress, suggesting potential clinical relevance for evaluating body image concerns in persons with CHD.

Background: Heart failure may cause peripheral and respiratory muscle alterations, dyspnea, fatigue, and exercise intolerance, worsening the quality of life of patients.

Objectives: The aims of this study were to analyze respiratory muscle strength and quality of life of patients with heart failure and correlate them with clinical variables and functional classification.

Methods: This cross-sectional study involved patients with heart failure. A manovacuometer assessed maximum inspiratory and expiratory pressures, and quality of life was assessed using the Minnesota Living with Heart Failure Questionnaire. Functional classification was categorized according to the New York Heart Association (NYHA) class in I, II, III, or IV.

Results: We included 60 patients (66.7% male) with a mean age of 62.0 years and mean left ventricular ejection fraction of 42.0%. Maximum inspiratory pressure and maximum expiratory pressure were close to normal (>70% of predicted) in most patients; however, a subgroup composed mostly of patients with dilated heart failure and NYHA class III (n = 21) presented low maximum inspiratory pressure values (59.2%; 95% confidence interval, 55.7%-62.8%). The mean total score of the Minnesota Living with Heart Failure Questionnaire was 44.4 points, being negatively correlated with left ventricular ejection fraction ( r = -0.29, P = .02). Patients with NYHA class III and disease duration longer than 120 months presented higher total ( P < .01) and physical dimension scores.

Conclusions: Most patients had respiratory muscle strength close to normal; however, those with dilated heart failure and NYHA class III presented low maximum inspiratory pressure values. Quality of life was moderately compromised, mainly because of long disease duration, NYHA class III, and low left ventricular ejection fraction.

Background: Ventricular assist device (VAD) implantation has become an alternative treatment for patients with end-stage heart failure. In Germany, valid and reliable instruments to assess health-related quality of life in patients with VAD are lacking.

Objective: The aim of this study was to present the psychometric validation of the German version of the Quality of Life with a Ventricular Assist Device questionnaire.

Methods: In a multicenter, cross-sectional study, 393 participants (mean age, 58.3 years; 85.8% male, 60.3% bridge to transplant, and 72.8% living with VAD for ≤2 years) completed the German Quality of Life with a Ventricular Assist Device questionnaire of physical, emotional, social, cognitive, and meaning/spiritual domains. Item and confirmatory factor analyses were conducted to test item difficulty and discrimination and the underlying structure, respectively. To examine internal consistency, Cronbach α was assessed. Convergent construct validity was tested using the Kansas City Cardiomyopathy Questionnaire and the Patient Health Questionnaire-9. Readability was examined using Flesch Reading Ease index and Vienna Factual Text Formula.

Results: The Quality of Life with a Ventricular Assist Device showed reasonable item difficulty ( Ptotal = .67) and mostly moderate to high discriminatory power ( rit > 0.30). In confirmatory factor analysis, root-mean-square error of approximation (0.07) was acceptable for model fit, but no other indices. Acceptable internal consistency was found ( α ≥ 0.79), with the exception of the cognitive domain ( α = 0.58). The overall questionnaire and single domains demonstrated convergent validity ( r ≥ 0.45, P < .001). The questionnaire showed adequate readability (Flesch Reading Ease, 64.11; Vienna Factual Text Formula, 6.91).

Conclusion: Findings indicate a promising standardized clinical instrument to assess health-related quality of life in patients with VAD.

Background: Black race, inadequate health literacy, and poor perceived control are predictors of increased cardiovascular disease (CVD) risk. The purpose of this study was to explore the relationships among race, health literacy, perceived control, and CVD risk while controlling for known risk factors in incarcerated men.

Methods: We included data from 349 incarcerated men to examine race and CVD risk (Framingham Risk Score) using a serial mediation model with health literacy and perceived control using 95% confidence intervals (CIs) from 5000 bootstrap samples.

Results: Of the participants (age, 36 ± 10; education, 12 ± 2; body mass index, 28.3 ± 5.0), 64.2% were White and 35.8% were Black. Black incarcerated men were younger ( P = .047) with lower levels of health literacy ( P < .001). All 3 indirect effects of race on CVD were significant, whereas the direct effect of race was not. Black incarcerated men had higher levels of CVD risk through health literacy ( a1b1 = 0.3571; 95% CI, 0.0948-0.7162) and lower levels of CVD risk through perceived control ( a2b2 = -0.1855; 95% CI, -0.4388 to -0.0077). Black incarcerated men had higher levels of CVD risk through health literacy influenced by perceived control ( a1b2d21 = 0.0627; 95% CI, 0.0028-0.1409), indicating that despite the protective effect of higher levels of perceived control in Black incarcerated men, CVD risk remained higher compared with their White counterparts.

Conclusion: Future CVD risk reduction interventions in incarcerated men, specifically Black incarcerated men, should include goals of improving health literacy and perceived control as modifiable risk factors.

Background: Family caregivers are at a high risk for low quality of life due to caregiving-related stress. Caregivers' stress is commonly assessed using self-reported measures, which reflect relatively subjective and long-term stress related to caregiving, but objective biological markers of stress are rarely used for caregivers. The purposes of this study were (1) to determine whether caregiver characteristics were associated with stress assessed using a stress biomarker (serum cortisol) and a self-reported caregiving distress measure (Caregiver Burden Inventory) and (2) to determine the predictability of both stress measures for quality of life in caregivers of patients with heart failure.

Methods: Taiwanese family caregivers (N = 113; mean age, 54.5 years; 70.8% female) of patients with heart failure completed surveys including caregiving distress and quality of life measured by the Caregiver Burden Inventory and the Short Form-36 (physical and psychological well-being subscales), respectively, and provided blood samples for serum cortisol. Independent t tests, correlation, and hierarchical regression were conducted.

Results: Single caregivers had higher serum cortisol levels than married caregivers ( P = .002). Men had significantly higher serum cortisol levels than women ( P = .010), but men reported lower caregiving distress than women ( P = .049). Both serum cortisol (β = -0.32, P = .012) and caregiving distress (β = -0.29, P = .018) were significant predictors of quality of life in the physical well-being scale while controlling for caregivers' characteristics and depressive symptoms. Serum cortisol (β = -0.28, P = .026) and caregiving distress (β = -0.25, P = .027) also predicted quality of life in the psychological well-being scale.

Conclusions: Serum cortisol and self-reported caregiving distress have similar predictability for quality of life in family caregivers of patients with heart failure. Reducing stress and caregiving distress is critical to improving quality of life in this population.

Background: Heart failure demands self-care skills and behaviors that can be negatively impacted by a low level of perceived control (PC), a belief about having the necessary resources to deal with negative events. Having valid and reliable instruments to measure PC is important to support interventions that improve self-care and related outcomes. The Control Attitudes Scale-Revised (CAS-R) was developed in the United States to measure PC in cardiac conditions. In Brazil, there are no instruments available to measure this construct.

Objective: The aims of this study were to translate and adapt the CAS-R to the Brazilian population and to assess the content validity of the adapted version.

Methods: The CAS-R was translated, back-translated, and assessed by an expert committee for linguistic equivalences. An agreement > 80% was considered adequate. Content validity (clarity, theoretical relevance, and practical pertinence) was assessed by both an expert professional panel (n = 6-8) and a panel of patients with heart failure (n = 40). A content validity coefficient > 0.70 was considered acceptable.

Results: The translations to Brazilian Portuguese were considered consistent with the original CAS-R. In the third round of linguistic equivalence assessment, all items achieved acceptable agreement, except for 2 items. After modifications to the instrument to achieve adequate equivalences, the adapted version had a final content validity coefficient of 0.93. Most patients were able to understand the instrument.

Conclusions: The CAS-R-Brazilian version is equivalent to the original CAS-R and has satisfactory evidence of content validity. Additional psychometric testing will be performed to allow for the assessment of PC in individuals with heart failure in Brazil.
