Life Course Cardiovascular Health: Risk Factors, Outcomes, and Interventions.

Since it was first defined by the American Heart Association in 2010, cardiovascular health (CVH) has been extensively studied across the life course. In this review, we present the current literature examining early life predictors of CVH, the later life outcomes of child CVH, and the relatively few interventions which have specifically addressed how to preserve and promote CVH across populations. We find that research on CVH has demonstrated that prenatal and childhood exposures are consistently associated with CVH trajectories from childhood through adulthood. CVH measured at any point in life is strongly predictive of future cardiovascular disease, dementia, cancer, and mortality as well as a variety of other health outcomes. This speaks to the importance of intervening early to prevent the loss of optimal CVH and the accumulation of cardiovascular risk. Interventions to improve CVH are not common but those that have been published most often address multiple modifiable risk factors among individuals within the community. Relatively few interventions have been focused on improving the construct of CVH in children. Future research is needed that will be both effective, scalable, and sustainable. Technology including digital platforms as well as implementation science will play key roles in achieving this vision. In addition, community engagement at all stages of this research is critical. Lastly, prevention strategies that are tailored to the individual and their context may help us achieve the promise of personalized prevention and help promote ideal CVH in childhood and across the life course.

Interventions on residual lesions in patients with heterotaxy syndrome following orthotropic heart transplantation: A single-center experience.

BACKGROUND: Heterotaxy syndrome (HS) is a defect in lateralization which often results in complex intra and extracardiac abnormalities. Orthotropic heart transplantation (OHT) in HS involves intricate and individualized modifications to surgical technique. Post-OHT outcomes are worse in patients with HS, however, the impact of post-OHT residual lesions has not yet been characterized. METHODS: Patients with HS who underwent OHT at Ann & Robert H. Lurie Children's Hospital of Chicago between January 2012 and June 2023 were identified. Patients were excluded if follow-up data was not available due to follow up at a different institution of early mortality. Pre-OHT clinical data, surgical data, and post-OHT surgical and catheterization data were collected. RESULTS: Two early mortalities were excluded from analysis, leaving 15 patients in the study cohort. Median age at OHT was 3.7 years (range: 0.7-15.4). Nine out of 15 patients were diagnosed with residual lesions requiring intervention at a median of 188 days post transplantation. All interventions on residual lesions occurred via catheterization. Overall mortality rate was 27% (4/15) with all deaths occurring in patients with residual lesions (4/9 patients, 44%). 83% (10/12) of lesions were diagnosed via catheterization, and 83% (10/12) of lesions of occurred in the first year after transplant. CONCLUSIONS: Patients with HS are at high risk for residual lesions after OHT, which may contribute to increased mortality. Comprehensive invasive diagnostics were required to diagnose residual lesions, which were all addressed percutaneously.

Technology-Delivered Adaptations of Motivational Interviewing for the Prevention and Management of Chronic Diseases: Scoping Review.

BACKGROUND: Motivational interviewing (MI) can increase health-promoting behaviors and decrease health-damaging behaviors. However, MI is often resource intensive, precluding its use with people with limited financial or time resources. Mobile health-based versions of MI interventions or technology-delivered adaptations of MI (TAMIs) might increase reach. OBJECTIVE: We aimed to understand the characteristics of existing TAMIs. We were particularly interested in the inclusion of people from marginalized sociodemographic groups, whether the TAMI addressed sociocontextual factors, and how behavioral and health outcomes were reported. METHODS: We employed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews to conduct our scoping review. We searched PubMed, CINAHL, and PsycInfo from January 1, 1996, to April 6, 2022, to identify studies that described interventions incorporating MI into a mobile or electronic health platform. For inclusion, the study was required to (1) describe methods/outcomes of an MI intervention, (2) feature an intervention delivered automatically via a mobile or electronic health platform, and (3) report a behavioral or health outcome. The exclusion criteria were (1) publication in a language other than English and (2) description of only in-person intervention delivery (ie, no TAMI). We charted results using Excel (Microsoft Corp). RESULTS: Thirty-four studies reported the use of TAMIs. Sample sizes ranged from 10 to 2069 participants aged 13 to 70 years. Most studies (n=27) directed interventions toward individuals engaging in behaviors that increased chronic disease risk. Most studies (n=22) oversampled individuals from marginalized sociodemographic groups, but few (n=3) were designed specifically with marginalized groups in mind. TAMIs used text messaging (n=8), web-based intervention (n=22), app + text messaging (n=1), and web-based intervention + text messaging (n=3) as delivery platforms. Of the 34 studies, 30 (88%) were randomized controlled trials reporting behavioral and health-related outcomes, 23 of which reported statistically significant improvements in targeted behaviors with TAMI use. TAMIs improved targeted health behaviors in the remaining 4 studies. Moreover, 11 (32%) studies assessed TAMI feasibility, acceptability, or satisfaction, and all rated TAMIs highly in this regard. Among 20 studies with a disproportionately high number of people from marginalized racial or ethnic groups compared with the general US population, 16 (80%) reported increased engagement in health behaviors or better health outcomes. However, no TAMIs included elements that addressed sociocontextual influences on behavior or health outcomes. CONCLUSIONS: Our findings suggest that TAMIs may improve some health promotion and disease management behaviors. However, few TAMIs were designed specifically for people from marginalized sociodemographic groups, and none included elements to help address sociocontextual challenges. Research is needed to determine how TAMIs affect individual health outcomes and how to incorporate elements that address sociocontextual factors, and to identify the best practices for implementing TAMIs into clinical practice.

Employment Loss and Food Insecurity - Race and Sex Disparities in the Context of COVID-19.

INTRODUCTION: Applying an intersectional framework, we examined sex and racial inequality in COVID-19-related employment loss (ie, job furlough, layoff, and reduced pay) and food insecurity (ie, quality and quantity of food eaten, food worry, and receipt of free meals or groceries) among residents in Saint Louis County, Missouri. METHODS: We used cross-sectional data from adults aged 18 or older (N = 2,146), surveyed by using landlines or cellular phones between August 12, 2020, and October 27, 2020. We calculated survey-weighted prevalence of employment loss and food insecurity for each group (Black female, Black male, White female, White male). Odds ratios for each group were estimated by using survey-weighted binary and multinomial logistic regression models. RESULTS: Black female residents had higher odds of being laid off, as compared with White male residents (OR = 2.61, 95% CI, 1.24-5.46). Both Black female residents (OR = 4.13, 95% CI, 2.29-7.45) and Black male residents (OR = 2.41, 95% CI, 1.15-5.07) were more likely to receive free groceries, compared with White male residents. Black female (OR = 4.25, 95% CI, 2.28-7.94) and White female residents (OR = 1.93, 95% CI, 1.04-3.60) had higher odds of sometimes worrying about food compared with White male residents. Black women also had higher odds of always or nearly always worrying about food, compared with White men (OR = 2.99, 95% CI, 1.52-5.87). CONCLUSION: Black women faced the highest odds of employment loss and food insecurity, highlighting the disproportionate impact of COVID-19 among people with intersectional disadvantages of being both Black and female. Interventions to reduce employment loss and food insecurity can help reduce the disproportionately negative social effects among Black women.

Role of t-tubule remodeling on mechanisms of abnormal calcium release during heart failure development in canine ventricle.

The goal of this work was to investigate the role of t-tubule (TT) remodeling in abnormal Ca2+ cycling in ventricular myocytes of failing dog hearts. Heart failure (HF) was induced using rapid right ventricular pacing. Extensive changes in echocardiographic parameters, including left and right ventricular dilation and systolic dysfunction, diastolic dysfunction, elevated left ventricular filling pressures, and abnormal cardiac mechanics, indicated that severe HF developed. TT loss was extensive when measured as the density of total cell volume, derived from three-dimensional confocal image analysis, and significantly increased the distances in the cell interior to closest cell membrane. Changes in Ca2+ transients indicated increases in heterogeneity of Ca2+ release along the cell length. When critical properties of Ca2+ release variability were plotted as a function of TT organization, there was a complex, nonlinear relationship between impaired calcium release and decreasing TT organization below a certain threshold of TT organization leading to increased sensitivity in Ca2+ release below a TT density threshold of 1.5%. The loss of TTs was also associated with a greater incidence of triggered Ca2+ waves during rapid pacing. Finally, virtually all of these observations were replicated by acute detubulation by formamide treatment, indicating an important role of TT remodeling in impaired Ca2+ cycling. We conclude that TT remodeling itself is a major contributor to abnormal Ca2+ cycling in HF, reducing myocardial performance. The loss of TTs is also responsible for a greater incidence of triggered Ca2+ waves that may play a role in ventricular arrhythmias arising in HF.NEW & NOTEWORTHY Three-dimensional analysis of t-tubule density showed t-tubule disruption throughout the whole myocyte in failing dog ventricle. A double-linear relationship between Ca2+ release and t-tubule density displays a steeper slope at t-tubule densities below a threshold value (∼1.5%) above which there is little effect on Ca2+ release (T-tubule reserve). T-tubule loss increases incidence of triggered Ca2+ waves. Chemically induced t-tubule disruption suggests that t-tubule loss alone is a critical component of abnormal Ca2+ cycling in heart failure.

Urinary Incontinence in Primary Care-The Gap Between Recommendations and Real World.

IMPORTANCE: Routine screening for urinary incontinence (UI) by primary care providers (PCPs) is recommended. OBJECTIVES: We aimed to describe the rate of incident UI diagnosed at annual PCP visits, the prevalence of UI in a large primary care population, and estimate the rate of screening for UI during primary care preventive and annual wellness visits. Secondary aims were to describe PCP knowledge and behavior as they relate to UI screening and diagnosis. STUDY DESIGN: The electronic health record was used to abstract the number of adult female patients seen by PCPs within a regional health system with a diagnosis of UI before our study period and with a new diagnosis over a 2-year period. Additional new diagnoses and screening practices were found on chart review of an additional 824 representative charts. Primary care providers within the health system were surveyed about their screening practices and knowledge about UI. RESULTS: There were 192,053 women primary care patients seen over 2 years. A total of 5.7% had a UI diagnosis preceding the study period and 3.4% had a UI diagnosis during the study period. A total of 42% of PCPs reported that they screen for UI at least half the time and none were completely satisfied with their ability to screen for UI. Sixteen percent of annual wellness visits had any documentation of screening for UI. CONCLUSION: In a large primary care population, screening for and detection of UI in women was low.

Prevalence and Trends in Cardiovascular Risk Factors Among Middle Aged Persons from Five Race and Ethnic Groups in the United States: A Longitudinal Analysis of Two Cohort Studies.

Importance: It is well established that people of South Asian background have a high burden of atherosclerotic cardiovascular disease (ASCVD). However, few studies have comprehensively examined if South Asian adults in the United States (US) develop cardiovascular risk factors at younger ages than adults from other race and ethnic groups. Objective: To compare the prevalence and change in ASCVD risk factors across age strata by race and ethnic group. Design: We combined data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) and the Multi-Ethnic Study of Atherosclerosis (MESA) cohort studies. Longitudinal data from all eligible participants at all available exam visits were used to estimate the prevalence of risk factors at ages 45 and 55 years for each race and ethnic group. Setting: Multicenter longitudinal cohort study in 7 field centers across the U.S. Participants: The baseline study sample included individuals free of clinical ASCVD; 554 South Asians, 796 White, 588 Black, 517 Hispanic/Latino, and 245 Chinese adults aged 45-55 years were included. Exposures: Self-identified race (Black, Chinese, South Asian, or White) or ethnic group (Hispanic/Latino). Main Outcomes and Measures: Prevalence of clinical (prediabetes & diabetes, hypertension, dyslipidemia, BMI) and behavioral (diet quality, alcohol use, exercise) ASCVD risk factors at age 45 and age 55. Results: At age 45, South Asian men and women had the highest prevalence of pre-diabetes and diabetes and higher prevalence of hypertension compared to White, Chinese, and Hispanic/Latino men and women. South Asian men had a higher prevalence of dyslipidemia than White, Chinese, and Black men, and South Asian women had a higher prevalence than Chinese and Black women. All groups had worse diet quality than South Asian men and women at age 45, and most also had higher rates of alcohol use. Conclusions and Relevance: We observed significant differences in the prevalence of risk factors for South Asian adults compared to adults from other U.S. race and ethnic groups at age 45 years. Understanding trends and disparities in cardiovascular risk and protective factors across the life course can help equitably improve prevention and treatment strategies for US populations. Key Points: Question: Do South Asian adults have a higher burden of cardiovascular risk factors at age 45 years compared adults from other race and ethnic groups?Findings: In this study of 2754 adults from two cohort studies, the prevalence of prediabetes and diabetes at age 45 years was higher among South Asians than in Black, Chinese, Hispanic and White adults; hypertension prevalence was higher among South Asians than all groups except Black adults.Meaning: South Asian adults have a higher prevalence of several clinical cardiovascular risk factors at a younger age.

Planning the Implementation of a Multilevel Blood Pressure Control Intervention in Chicago: Community and Clinical Perspectives.

Objectives: Hypertension is associated with high morbidity and mortality. The complications of hypertension disproportionately impact African American residents in Chicago's South Side neighborhood. To inform the implementation of an evidence-based multilevel hypertension management intervention, we sought to identify community member- and clinician-level barriers to diagnosing and treating hypertension, and strategies for addressing those barriers. Methods: We conducted 5 focus groups with members of faith-based organizations (FBOs) (n=40) and 8 focus groups with clinicians and administrators (n=26) employed by community health centers (CHCs) located in Chicago's South Side. Results: Participants across groups identified the physical environment, including lack of access to clinics and healthy food, as a risk factor for hypertension. Participants also identified inconsistent results from home blood pressure monitoring and medication side effects as barriers to seeking diagnosis and treatment. Potential strategies raised by participants to address these barriers included (1) addressing patients' unmet social needs, such as food security and transportation; (2) offering education that meaningfully engages patients in discussions about managing hypertension (eg, medication adherence, diet, follow-up care); (3) coordinating referrals via community-based organizations (including FBOs) to CHCs for hypertension management; and (4) establishing a setting where community members managing hypertension diagnosis can support one another. Conclusions: Clinic-level barriers to the diagnosis and treatment of hypertension, such as competing priorities and resource constraints, are exacerbated by community-level stressors. Community members and clinicians agreed that it is important to select implementation strategies that leverage and enhance both community- and clinic-based resources.

Late results after stand-alone surgical ablation for atrial fibrillation.

OBJECTIVES: Stand-alone surgical ablation of atrial fibrillation is indicated in patients with refractory atrial fibrillation who have failed medical or catheter-based ablation. Few reports of late outcomes after stand-alone surgical ablation exist using comprehensive follow-up with strict definitions of success. This study examined our late outcomes of the stand-alone Cox-Maze IV procedure. METHODS: Between January 2003 and December 2019, 236 patients underwent a stand-alone Cox-Maze IV for refractory atrial fibrillation. Freedom from atrial tachyarrhythmias was assessed by electrocardiography, Holter, or pacemaker interrogation for up to 10 years, with a mean follow-up of 4.8 ± 3.5 years. Rhythm outcomes were compared in multiple subgroups. Factors associated with recurrence were determined using Fine-Gray regression, allowing for death as the competing risk. RESULTS: The majority of patients (176/236, 75%) had nonparoxysmal atrial fibrillation. Median duration of preoperative atrial fibrillation was 6.2 years (interquartile range, 3-11). Fifty-nine percent of patients (140/236) failed 1 or more prior catheter-based ablation. Thirteen patients (6%) experienced a major complication. There was no 30-day mortality. Freedom from atrial tachyarrhythmias was 94% (187/199), 89% (81/91), and 77% (24/31) at 1, 5, and 10 years, respectively. There was no difference in freedom from atrial tachyarrhythmias between patients with paroxysmal atrial fibrillation versus nonparoxysmal atrial fibrillation (P > .05) or those undergoing sternotomy versus a minimally invasive approach (P > .05). Increased left atrial size and number of catheter ablations were associated with late atrial fibrillation recurrence. For patients who experienced any atrial tachyarrhythmia recurrence, the median number of recurrences was 1.5 (1.0-3.0). CONCLUSIONS: The stand-alone Cox-Maze IV had excellent late efficacy at maintaining sinus rhythm in patients with symptomatic, refractory atrial fibrillation, with low morbidity and no mortality. The Cox-Maze IV, in contrast to catheter-based ablation, was equally effective in patients with paroxysmal and nonparoxysmal atrial fibrillation.
