The Burden of Cardiovascular Diseases Among US States, 1990-2016

Long Non-coding RNA PEBP1P2 Suppresses Proliferative VSMCs Phenotypic Switching and Proliferation in Atherosclerosis

Long non-coding RNAs (lncRNAs) play a crucial role in the growth of vascular smooth muscle cells (VSMCs), the dysfunction of which is closely associated with the initiation and progression of cardiovascular diseases (CVDs). Abnormal phenotypic switching and proliferation of VSMCs constitute a significant event in the progression of atherosclerosis. The present study identified a novel lncRNA, PEBP1P2, which serves as a valuable regulator of VSMCs in phenotypic transformation and proliferation. The expression of PEBP1P2 was remarkably decreased in proliferating VSMCs and pathological arteries when using a balloon injury model of rats. Furthermore, we found that PEBP1P2 represses proliferation, migration, and dedifferentiation during phenotype switching in VSMCs induced by platelet-derived growth factor BB (PDGF-BB). Mechanistically, cyclin-dependent kinase 9 (CDK9) was confirmed to be the direct target of PEBP1P2, which was proven to mediate phenotypic switching and proliferation of VSMCs and was rescued by PEBP1P2. Then, we explored the clinical significance, as we observed the decreased expression of PEBP1P2 in the serum of coronary heart disease (CHD) patients and human advanced carotid atherosclerotic plaques. Finally, PEBP1P2 overexpression distinctly suppressed neointima formation and VSMC phenotypic switching in vivo. Taken together, PEBP1P2 inhibits proliferation and migration in VSMCs by directly binding to CDK9, implying that it may be a promising therapeutic target for the treatment of proliferative vascular diseases.

Heterogeneous trends in burden of heart disease mortality by subtypes in the United States, 1999-2018: observational analysis of vital statistics

OBJECTIVE

To describe trends in the burden of mortality due to subtypes of heart disease from 1999 to 2018 to inform targeted prevention strategies and reduce disparities.

DESIGN

Serial cross sectional analysis of cause specific heart disease mortality rates using national death certificate data in the overall population as well as stratified by race-sex, age, and geography.

SETTING

United States, 1999-2018.

PARTICIPANTS

12.9 million decedents from total heart disease (49% women, 12% black, and 19% <65 years old).

MAIN OUTCOME MEASURES

Age adjusted mortality rates (AAMR) and years of potential life lost (YPLL) for each heart disease subtype, and respective mean annual percentage change.

RESULTS

Deaths from total heart disease fell from 752 192 to 596 577 between 1999 and 2011, and then increased to 655 381 in 2018. From 1999 to 2018, the proportion of total deaths from heart disease attributed to ischemic heart disease decreased from 73% to 56%, while the proportion attributed to heart failure increased from 8% to 13% and the proportion attributed to hypertensive heart disease increased from 4% to 9%. Among heart disease subtypes, AAMR was consistently highest for ischemic heart disease in all subgroups (race-sex, age, and region). After 2011, AAMR for heart failure and hypertensive heart disease increased at a faster rate than for other subtypes. The fastest increases in heart failure mortality were in black men (mean annual percentage change 4.9%, 95% confidence interval 4.0% to 5.8%), whereas the fastest increases in hypertensive heart disease occurred in white men (6.3%, 4.9% to 9.4%). The burden of years of potential life lost was greatest from ischemic heart disease, but black-white disparities were driven by heart failure and hypertensive heart disease. Deaths from heart disease in 2018 resulted in approximately 3.8 million potential years of life lost.

CONCLUSIONS

Trends in AAMR and years of potential life lost for ischemic heart disease have decelerated since 2011. For almost all other subtypes of heart disease, AAMR and years of potential life lost became stagnant or increased. Heart failure and hypertensive heart disease account for the greatest increases in premature deaths and the largest black-white disparities and have offset declines in ischemic heart disease. Early and targeted primary and secondary prevention and control of risk factors for heart disease, with a focus on groups at high risk, are needed to avoid these suboptimal trends beginning earlier in life.

Association between body mass index and hypertension subtypes in Indian and United States adults

The purpose of this cross-sectional, secondary analysis was to determine the association between BMI & lipids and hypertension subtype in U.S. and Indian adults. Obese BMI was significantly associated with isolated diastolic hypertension (IDH) compared to low/normal BMI (relative risk ratio [95% CI]; U.S.: 4.33 [2.88,6.52]; India: 2.51 [2.41,2.60]). Furthermore, BMI was more strongly associated with IDH than other hypertension subtypes in U.S. and non-obese Indian adults. In obese Indian adults, we observed higher odds of isolated systolic hypertension until the 6th decade, and systo-diastolic hypertension thereafter. Triglyceride levels were associated with IDH in U.S. adults (1.94 [1.43,2.63]).

Breaking down walls: a qualitative evaluation of perceived emergency department delays for patients transferred with ST-elevation myocardial infarction

Background

Despite regionalization efforts, delays at transferring hospitals for patients transferred with ST-elevation myocardial infarction (STEMI) for primary percutaneous coronary intervention (PCI) persist. These delays primarily occur in the emergency department (ED), and are associated with increased mortality. We sought to use qualitative methods to understand staff and clinician perceptions underlying these delays.

Methods

We conducted semi-structured interviews at 3 EDs that routinely transfer STEMI patients to identify staff perceptions of delays and potential interventions. Interviews were recorded, transcribed, coded, and analyzed using an iterative inductive-deductive approach to build and refine a list of themes and subthemes, and identify supporting quotes.

Results

We interviewed 43 ED staff (staff, nurses, and physicians) and identified 3 major themes influencing inter-facility transfers of STEMI patients: 1) Processes, 2) Communication; and 3) Resources. Standardized processes (i.e., protocols) reduce uncertainty and can mobilize resources. Use of performance benchmarks can motivate staff but are frequently focused on internal, not inter-organizational performance. Direct use ofcommunication between ORGANIZATIONS can process uncertainty and expedite care. Record sharing and regular post-transfer communication could provide opportunities to discuss and learn from delays and increase professional satisfaction. Finally, characteristics of resources that enhanced their capacity, clarity, experience, and reliability were identified as contributing to timely transfers.

Conclusions

Processes, communication, and resources were identified as modifying inter-facility transfer timeliness. Potential quality improvement strategies include ongoing updates of protocols within and between organizations to account for changes, enhanced post-transfer feedback between organizations, shared medical records, and designated roles for coordination.

A Greater Flavonoid Intake Is Associated with Lower Total and Cause-Specific Mortality: A Meta-Analysis of Cohort Studies

Introduction: The links between flavonoid intake and mortality were previously evaluated in epidemiological studies. The aim of the present study was to perform a systematic review and meta-analysis of cohort studies evaluating the link of flavonoid consumption with total and cause-specific mortality. Methods: Prospective cohort studies reporting flavonoid intake and mortality data published up to 30th April 2019 (without language restriction) were searched using PubMed, Scopus and EMBASE database. Generic inverse variance methods and random effects models were used to synthesize pooled and quantitative data. Sensitivity analysis was also performed by a leave-one-out method. Results: Overall, 16 articles met the inclusion criteria (nine studies were performed in Europe, five in the USA, one in Asia and one in Oceania); a total of 462,194 participants (all adults aged >19 years) with 23,473 mortality cases were included in the final analysis. The duration of follow-up ranged from 4.8 to 28 years. Most of the studies assessed flavonoid intake using food frequency questionnaires, whereas four studies used interviews and 1 study used 4-day food records. The meta-analysis showed that flavonoid consumption was inversely and significantly associated with total (relative risk (RR): 0.87, 95% confidence interval (CI) = 0.77-0.99) and cardiovascular disease mortality risk (RR: 0.85, 95%CI = 0.75-0.97), but not cancer (0.86, 95%CI = 0.65-1.14) mortality risk. These findings remained robust in sensitivity analyses. Conclusions: The present findings highlight the potential protective role of flavonoids against total and cause-specific mortality. These results support the recommendations for flavonoid-rich foods intake to prevent chronic diseases.

Left Ventricular Mass Index Is Associated With Cognitive Function in Middle-Age: Bogalusa Heart Study

BACKGROUND

Elevated cardiovascular disease risk factor burden is a recognized contributor to poorer cognitive function; however, the physiological mechanisms underlying this association are not well understood. We sought to assess the potential mediation effect of left ventricular (LV) remodeling on the association between lifetime systolic blood pressure and cognitive function in a community-based cohort of middle-aged adults.

METHODS

Nine hundred sixty participants of the Bogalusa Heart Study (59.2% women, 33.8% black, aged 48.4±5.1 years) received 2-dimensional echocardiography to quantify relative wall thickness, LV mass, and diastolic and systolic LV function; and a standardized neurocognitive battery to assess memory, executive functioning, and language processing. Multivariable linear regression assessed the association of cardiac structure and function with a global composite cognitive function score, adjusting for traditional cardiovascular disease risk factors. Mediation analysis assessed the effect of LV mass index on the association between lifetime systolic blood pressure burden and cognitive function.

RESULTS

There were 233 (24.3%) and 136 (14.2%) individuals with concentric LV remodeling and concentric LV hypertrophy, respectively. Each g/m2.7 increment in LV mass index was associated with a 0.03 standardized unit decrement in global cognitive function (P=0.03). Individuals with concentric LV remodeling and isolated diastolic dysfunction had the poorest cognitive function, and a greater ratio between early mitral inflow velocity and early diastolic mitral annular velocity (E/e') was associated with poorer cognitive function, even after adjustment for LV mass index (B=-0.12; P=0.03). A total of 18.8% of the association between lifetime systolic blood pressure burden and midlife cognitive function was accounted for by LV mass index.

CONCLUSIONS

Cardiac remodeling partially mediates the association between lifespan systolic blood pressure burden and adult cognition in individuals without dementia or clinical cardiovascular disease. Slowing or reversing the progression of cardiac remodeling in middle-age may be a novel therapeutic approach to prevent cognitive decline.

Inequalities and Deteriorations in Cardiovascular Health in Premenopausal US Women, 1990-2016

Coronary heart disease (CHD) mortality rates in the United States have declined by up to two thirds in recent decades. Closer examination of these trends reveals substantial inequities in the distribution of mortality benefits. It is worrying that the uneven distribution of CHD that exists from lowest to highest social class-the social gradient-has become more pronounced in the United States since 1990 and is most pronounced for women.Here we consider ways in which this trend disproportionately affects premenopausal women aged 35 to 54 years. We apply a social determinants of health framework focusing on intersecting axes of inequalities-notably gender, class, ethnicity, geographical location, access to wealth, and class-among other power relations to which young and middle-aged women are especially vulnerable, and we argue that increasing inequalities may be driving these unprecedented deteriorations. We conclude by discussing interventions and policies to target and alleviate inequality axes that have potential to promote greater equity in the distribution of CHD mortality and morbidity gains.The application of this framework in the context of women's cardiovascular health can help shed light regarding why we are seeing persistently poorer outcomes for premenopausal US women.

What is the Impact of Cinnamon Supplementation on Blood Pressure? A Systematic Review and Meta-Analysis

AIM

This study was designed to make a systematic review and meta-analysis on randomized controlled trials (RCTs) assessing the effect of cinnamon on blood pressure (BP).

METHODS

A systematic computerized literature search of PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar databases was conducted up to August 2019. All RCTs using cinnamon supplements in adults were included in this systematic review and meta-analysis.

RESULTS

Out of 927 records, 8 trials that enrolled 582 participants were included. The pooled effect size showed that SBP did not change following cinnamon supplementation. (WMD: -0.61mmHg; 95% CI: -1.36, 0.14, P= 0.111). Also cinnamon supplementation in long-duration (≥ 8weeks) had a significant effect on SBP (WMD: -1.25 mmHg; 95% CI: -2.22, -0.28, P= 0.012). Pooled analysis showed that cinnamon had a significant effect on DBP (WMD: -0.93mmHg, 95% CI: -1.55 to -0.32, P= 0.003). In addition, results from both duration subsets and high dose (>1500 mg/day) of cinnamon supplementation were significant.

CONCLUSION

Our findings revealed that cinnamon supplementation has favorable effects on DBP although results of SBP were not the same. Nonetheless, further studies are required.

Female and male US Olympic athletes live 5 years longer than their general population counterparts: a study of 8124 former US Olympians

Objective

To quantify US female and male Olympic athletes’ longevity and the years of life lost or saved due to multiple causes of death as compared with the US general population.

Methods

Former US athletes who had participated in the summer or winter Olympic Games at least once between 1912 and 2012 were included. Olympians’ date of birth, death and the underlying causes of death were certified by the National Death Index. The Olympians’ overall and cause-specific mortality were compared with the US general population based on the US life tables, adjusted by sex, period and age. Mortality differences between the populations were quantified using the years lost/years saved (YS) method.

Results

8124 US Olympians (2301 women and 5823 men) lived 5.1 years longer (YS 95% CI 4.3 to 6.0) than the general population, based on 2309 deaths observed (225 women, 2084 men). Different causes of death contributed to longevity for Olympians as follows: 2.2 years were saved (1.9 to 2.5) from cardiovascular diseases (CVDs); cancer, 1.5 years (1.3 to 1.8); respiratory diseases (eg, influenza, pneumonia), 0.8 years (0.7 to 0.9); external causes (eg, accidents, homicides), 0.5 years (0.4 to 0.6); endocrine and metabolic diseases (eg, diabetes, hyperlipidaemia), 0.4 years (0.2 to 0.5) and digestive system diseases (eg, cirrhosis, hepatic failure), 0.3 years (0.2 to 0.4). Mortality rates due to nervous system disorders (eg, Alzheimer’s and Parkinsons’s diseases) and mental illness (eg, dementia, schizophrenia) were not different from the general population.

Conclusion

US Olympians lived longer than the general population, an advantage mainly conferred by lower risks of CVD and cancer. Nervous system disorders and mental illness did not differ between US Olympians and the general population.

Race or racial segregation? Modification of the PM2.5 and cardiovascular mortality association

BACKGROUND

Many studies have identified an inequitable distribution of exposure to PM2.5 (particulate matter less than 2.5 microns) by race. We investigated the association of PM2.5 and cardiovascular mortality considering both the decedents' race and neighborhood racial composition as potential modifiers.

METHODS

We obtained geocoded cardiovascular mortality records of all black and white decedents from urban block-groups in Massachusetts between 2001 and 2011 (n = 130,863). We examined the association between PM2.5 and cardiovascular mortality, and assessed effect modification by three types of racial modifiers: decedents' race, census block-group percent black and white, and two novel measures of racial segregation. The Racial Residential Segregation (RRS) quantifies the concentration of non-Hispanic blacks and whites in each block-group. The Index of Racial Dissimilarity measures dissimilarity in non-Hispanic black and white racial distribution between the smaller census block-group and larger tract.

RESULTS

We found a 2.35%(95%CI: 0.92%;3.79%) increase in mortality for each 10μg/m3 increase in two-day average exposure to PM2.5. The effect was modified by the block-group racial composition, with higher risks in block-groups with the highest percentage of black residents (interaction p-value = 0.04), and in block-groups with the lowest RRS (i.e. higher black to white resident ratio, interaction p-value = 0.072). Racial dissimilarity did not modify the associations.

CONCLUSION

Current levels of PM2.5 are associated with increased cardiovascular deaths in Massachusetts, with different risks between areas with different racial composition and segregation. This suggests that pollution reductions in neighborhoods with the highest percentage of non-Hispanic blacks would be most beneficial in reducing cardiovascular mortality and disparities.

Escalating ischemic heart disease burden among women in India: Insights from GBD, NCDRisC and NFHS reports

Objective

To determine trends in ischemic heart disease (IHD) mortality and burden among women in India we performed a study.

Methods

Data were obtained from three publicly available resources. Cardiovascular disease (CVD) and IHD mortality were obtained from 2017 Global Burden of Diseases (GBD) Study. Metabolic risk factor data (body-mass index, blood pressure and diabetes) were obtained from Non-Communicable Disease Risk Factor Collaboration (NCDRiSC) and lifestyle factors were obtained from National Family Health Surveys (NFHS). Descriptive statistics are reported.

Results

GBD study reported that in year 2017 in India CVD caused 2.64 million deaths (women 1.18, men 1.45 million) and IHD 1.54 million (women 0.62, men 0.92 million). Burden of IHD related disability adjusted life years (DALYs) was 36.99 million (women 13.80, men 23.19 million). From 2000 to 2017 annual IHD mortality increased from 0.85 to 1.54 million (+81.1%) with greater increase in women 0.32 to 0.62 million (+93.7%) compared to men (0.53–0.92 million, +73.6%). Increase in age-adjusted IHD mortality rate/100,000 was also more in women (62.9–92.7, +47.4%) than men (97.5–129.5, +32.8%). Trends in cardiometabolic risk factors from 2000 to 2015 showed greater increase in body-mass index, diabetes, tobacco-use and periodontal infections among women than men.

Conclusion

IHD is increasing more rapidly among women than men in India and there is sex-associated convergence. This is associated with greater increase in overweight, diabetes, tobacco use and periodontal infections in women.

Etiological Role of Diet in 30-Day Readmissions for Heart Failure: Implications for Reducing Heart Failure-Associated Costs via Culinary Medicine

Background. Reducing the under-30-day readmission for heart failure (HF) patients is a modifiable quality-of-care measure, yet the role of diet in HF readmissions and cost-effective HF care remain ill-defined. Methods. Medical chart review was conducted to determine cause(s) for HF treatment failure. Randomized controlled trial-backed machine learning models were employed to assess the relationship of culinary medicine education with HF 30-day readmission rate and cost. Results. Of 1031 HF admissions, 130 occurred within 30 days of discharge (12.61%.) Nearly two-thirds of individuals were male (64.02%), while the mean age and median length of stay were 64.33 ± 14.02 and 2, respectively. Medication noncompliance (34.62%) was the most common etiology for 30-day readmissions, followed by dietary noncompliance (16.92%), comorbidity (16.92%), a combination of dietary and medication noncompliance (10%), HF exacerbation (10%), iatrogenic (10%), and drug abuse (1.54%). Medication noncompliance contributed to the highest gross charge by readmission, costing a total of $1 802 096. Compared with traditional care, culinary medicine education for HF patients would prevent 93 HF readmissions and save $3.9 million in an estimated 4-year period. Conclusion. Though pharmacological treatment remains a focal point of HF management, diet-based approaches may improve tertiary HF prevention and reduce HF-associated health care expenditures.

Identifying patterns and predictors of lifestyle modification in electronic health record documentation using statistical and machine learning methods

Just under half of the 85.7 million US adults with hypertension have uncontrolled blood pressure using a hypertension threshold of systolic pressure ≥ 140 or diastolic pressure ≥ 90. Uncontrolled hypertension increases risks of death, stroke, heart failure, and myocardial infarction. Guidelines on hypertension management include lifestyle modification such as diet and exercise. In order to improve hypertension control, it is important to identify predictors of lifestyle modification assessment or advice to tailor future interventions using these effective, low-risk interventions. Electronic health record data from 14,360 adult hypertension patients at an academic medical center were analyzed using statistical and machine learning methods to identify predictors and timing of lifestyle modification. Multiple variables were statistically significant in analysis of lifestyle modification documentation at multiple time points. Random Forest was the best machine learning method to classify lifestyle modification documentation at any time with Area Under the Receiver Operator Curve (AUROC) 0.831. Logistic regression was the best machine learning method for classifying lifestyle modification documentation at ≤3 months with an AUROC of 0.685. Analyzing narrative and coded data from electronic health records can improve understanding of timing of lifestyle modification and patient, clinic and provider characteristics that are correlated with or predictive of documentation of lifestyle modification for hypertension. This information can inform improvement efforts in hypertension care processes, treatment implementation, and ultimately hypertension control.

Development and Validation of a County-Level Social Determinants of Health Risk Assessment Tool for Cardiovascular Disease

PURPOSE

Social determinants of health (SDoH) have been linked to a variety of health conditions, but there are no multivariate measures of these determinants to estimate the risk of morbidity or mortality in a community. We developed a score derived from multivariate measures of SDoH that predicts county-level cardiovascular disease (CVD) mortality.

METHODS

Using county-level data from 3,026 US counties, we developed a score considering variables of neighborhood socioeconomic status, food/lifestyle environment, and health care resource availability and accessibility to predict the 3-year average (2015-2017) age-adjusted county-level mortality rate for all CVD. We used one 50% random sample to develop the score and the other to validate the score. A Poisson regression model was developed to estimate parameters of variables while accounting for intrastate correlation.

RESULTS

The index score was based on 7 SDoH factors: percentage of the population of minority (nonwhite) race, poverty rate, percentage of the population without a high school diploma, grocery store ratio, fast-food restaurant ratio, after-tax soda price, and primary care physician supply. The area under the curve for the development and validation groups was similar, 0.851 (95% CI, 0.829-0.872) and 0.840 (95% CI, 0.817-0.863), respectively, indicating excellent discriminative ability. The index had better predictive performance for CVD burden than other area-level indexes: poverty only (area under the curve= 0.808, P <.001); the Centers for Disease Control and Prevention's Social Vulnerability Index (CDC-SVI) (area under the curve =0.786, P <.001); and the Agency for Healthcare Research and Quality's Socioeconomic Status (AHRQ-SES) index (area under the curve =0.835, P = .03).

CONCLUSIONS

Our validated multivariate SDoH index score accurately classifies counties with high CVD burden and therefore has the potential to improve CVD risk prediction for vulnerable populations and interventions for CVD at the county level.

Trends in the Inpatient Burden of Coronary Artery Disease in Granulomatosis With Polyangiitis: A Study of a Large National Dataset

OBJECTIVE

Cardiovascular (CV) diseases are serious comorbidities in patients with granulomatosis with polyangiitis (GPA). In a sample of patients hospitalized for GPA, we sought to examine trends in the burden of coronary artery disease (CAD) and its 2 serious manifestations, acute myocardial infarction (AMI) and heart failure (HF).

METHODS

We used the National Inpatient Sample to conduct a retrospective cross-sectional analysis. Our sample consisted of hospitalizations for GPA between 2005 and 2014. We examined trends in the proportion of CAD, AMI, and HF in all hospitalizations with GPA compared to those without GPA. We used logistic regression adjusted for potential confounders and included interaction terms.

RESULTS

Among a total of 103,453 GPA hospitalizations, 20,351 (19.7%) hospitalizations had a concurrent diagnosis of CAD. GPA with CAD was associated with overall lower burden of traditional CV risk factors compared to non-GPA with CAD, with the exception of chronic kidney disease (57% vs 21%). Over the 10-year study period, there were rising trends in the inpatient burden of CAD (16.6% in 2005 to 22.7% in 2014) and CAD with HF (4.3% in 2005 to 9.9% in 2014), but not AMI (1.2% in 2005 to 1.1% in 2014), in GPA hospitalizations compared to non-GPA controls.

CONCLUSION

In this national sample of GPA hospitalizations, we found that the burden of CAD and CAD with HF was on the rise over the 10-year period compared to non-GPA; however, it was not the case for AMI.

Association of predicted lean body mass and fat mass with cardiovascular events in patients with type 2 diabetes mellitus

BACKGROUND

Previous studies have found that predicted fat mass and lean body mass may act differently on adverse events. However, the cardiovascular prognostic value of lean body mass and fat mass in patients with type 2 diabetes mellitus (T2DM) has not yet been investigated. We sought to investigate the relation between predicted lean body mass or fat mass and the risk of cardiovascular disease in patients with T2DM.

METHODS

We conducted a post hoc analysis of data from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study to investigate the relation between the predicted lean body mass or fat mass and major adverse cardiovascular events in patients with T2DM. We used sex-specific quartiles of predicted lean body mass index (BMI; kg/m²) and fat mass index (kg/m²). We defined a major adverse cardiovascular event as a composite of nonfatal myocardial infarction, nonfatal stroke or death from cardiovascular causes.

RESULTS

After a mean follow-up period of 8.8 years, we found that a major cardiovascular event occurred in 1801 of 10 251 patients (17.8%). Predicted lean BMI was not associated with major cardiovascular events (p = 0.34). Compared with patients in the first quartile (incidence rate 16.4%; 17.2%, 17.5% and 19.8% for the second, third and four quartiles, respectively) of predicted fat mass index, those in the fourth quartile had a hazard ratio of 1.53 (95% confidence interval 1.23-1.91).

INTERPRETATION

In patients with T2DM, we found that predicted fat mass had a strong positive association with a higher risk of a major adverse cardiovascular event. Increasing lean body mass did not have a protective role. Trial registration: ClinicalTrials.gov., no. NCT00000620.

Cardiovascular disease in Mexico 1990-2017: secondary data analysis from the global burden of disease study

OBJECTIVES

Cardiovascular diseases (CVD) are a major cause of death and a public health threat. To report the burden of CVD in Mexico at a national and subnational scale from 1990 to 2017 as well as risk factors driving these changes.

METHODS

Following the 2017 global burden of disease study, mortality, disability-adjusted life-years (DALYs), and risk factors of CVD were examined according to 10 subcategories.

RESULTS

The CVD burden of disease decreased between 1990 and 2017 in Mexico as a whole and in all states, with the higher decrease located in the north and central regions. Ischemic heart disease accounted for almost two-thirds of the total number of deaths from CVD and caused the highest DALY rate. The leading CVD risk factors were high systolic blood pressure, dietary risks, high LDL cholesterol, high BMI, and high fasting plasma glucose level.

CONCLUSIONS

These results allow the establishment of priorities, policy development, and implementation to decrease the CVD burden and can provide a benchmark for states to focus on key risk factors, improve the quality of health care, and reduce health care costs.

Pediatric Obesity, Hypertension, Lipids

PURPOSE OF REVIEW

The rise of the pediatric obesity pandemic over the past 40 years has sharpened focus on the management of obesity, hypertension and lipid abnormalities in children. Multiple studies demonstrate that these risk factors track from childhood into adulthood predisposing individuals to premature atherosclerotic cardiovascular disease and putting them at risk for early morbidity and mortality.

RECENT FINDINGS

Importantly, obesity, hypertension and lipid problems are individual risk factors that can occur independently. Multiple studies have shown that each risk factor causes target organ damage in children. Intensive and focused lifestyle modifications can improve a child's subclinical disease and decrease the risk for future morbidity.

SUMMARY

Childhood offers a unique opportunity at primordial and primary prevention of atherosclerotic cardiovascular disease. Clinicians must focus on targeting these highly prevalent conditions and applying lifestyle modification and then pharmacologic or surgical therapies as needed.

Pro-Senescence and Anti-Senescence Mechanisms of Cardiovascular Aging: Cardiac MicroRNA Regulation of Longevity Drug-Induced Autophagy

Chronological aging as well as biological aging accelerated by various pathologies such as diabetes and obesity contribute to cardiovascular aging, and structural and functional tissue damage of the heart and vasculature. Cardiovascular aging in humans is characterized by structural pathologic remodeling including cardiac and vascular fibrosis, hypertrophy, stiffness, micro- and macro-circulatory impairment, left ventricular diastolic dysfunction precipitating heart failure with either reduced or preserved ejection fraction, and cardiovascular cell death. Cellular senescence, an important hallmark of aging, is a critical factor that impairs repair and regeneration of damaged cells in cardiovascular tissues whereas autophagy, an intracellular catabolic process is an essential inherent mechanism that removes senescent cells throughout life time in all tissues. Several recent reviews have highlighted the fact that all longevity treatment paradigms to mitigate progression of aging-related pathologies converge in induction of autophagy, activation of AMP kinase (AMPK) and Sirtuin pathway, and inhibition of mechanistic target of rapamycin (mTOR). These longevity treatments include health style changes such as caloric restriction, and drug treatments using rapamycin, the first FDA-approved longevity drug, as well as other experimental longevity drugs such as metformin, rapamycin, aspirin, and resveratrol. However, in the heart tissue, autophagy induction has to be tightly regulated since evidence show excessive autophagy results in cardiomyopathy and heart failure. Here we discuss emerging evidence for microRNA-mediated tight regulation of autophagy in the heart in response to treatment with rapamycin, and novel approaches to monitor autophagy progression in a temporal manner to diagnose and regulate autophagy induction by longevity treatments.

Nutrition Disparities and Cardiovascular Health

PURPOSE OF REVIEW

This review is an assessment of the state of the science on nutrition disparities and their contribution to disparities in cardiovascular health.

RECENT FINDINGS

Nutrition disparities remain pervasive by race/ethnicity, sex/gender, socioeconomic status, and geography. They are rooted in differences in social, cultural, and environmental determinants of health, behavioral and lifestyle factors, and the impact of policy interventions. Systematic differences in diet quality, dietary patterns, and nutrient intakes contribute to cardiovascular disparities and are mediated by microbiota, and CVD risk factors including high levels of blood pressure, low density lipoprotein cholesterol (LDL), and glucose; oxidative stress, pro-inflammatory cytokines, and endothelial dysfunction. Despite the progress made in nutrition research, important gaps persist that signal the need for more effective interventions at multiple levels to reduce cardiovascular disparities. Research opportunities include (1) exploring the gene-nutrient-environment interactions in the context of ancestral diversity; (2) investigating the causal link between diet and gut microbiota and impact of social determinants of health; (3) understanding resilience; (4) testing the effectiveness of multi-level interventions that address social and environmental determinants; and (4) supporting intervention research informed by validated implementation science frameworks.

Incidental Coronary Artery Calcification and Stroke Risk in Patients With Atrial Fibrillation

OBJECTIVE. Atrial fibrillation (AF) is a major risk factor for stroke. The CHA₂DS_2-VASc score is used to risk stratify patients, and the score includes known coronary artery disease (CAD) as a variable. The aim of this study was to assess if the presence of incidental coronary artery calcification (CAC), without known CAD, is associated with stroke independent of CHA₂DS₂-VASc variables. MATERIALS AND METHODS. A retrospective review of health records was performed for patients who had AF, a chest CT scan performed within 1 year, and a subsequent visit for stroke. Patients with CAD and other vascular disease, a mechanical valve, or who were older than 74 years old were excluded. Included patients were one-to-one matched by age and CHA₂DS₂-VASc risk factors to patients who had had similar follow-up but who did not have a stroke. Nongated CT images were reviewed for CAC. Univariate and Cox regression analyses were performed. RESULTS. A total of 203 patients met the study criteria, and 203 matched patients without stroke were identified. Median age was 61 years old with stroke and 62 years old without stroke (p = 0.99). In both groups, 82 (39.0%) were women and the median CHA₂DS₂-VASc was 2 (interquartile range, 1-2). Anticoagulation medication was prescribed to 46 (22.7%) patients in the group who had had a stroke and 52 (25.6%) in the group without stroke (p = 0.49). On Cox regression analysis, CAC was associated with stroke (hazard ratio [HR], 1.47; 95% CI, 1.10-1.97; p < 0.01) and mortality (adjusted HR, 1.41; 95% CI, 1.02-1.95; p = 0.04). CONCLUSION. Patients with AF and incidental CAC depicted on chest CT have an increased risk of stroke and mortality beyond established risk factors.

Waist to Height Ratio and Metabolic Syndrome as lung dysfunction predictors

Metabolic Syndrome (MetS) has been related to pulmonary diseases but its relationship with lung age has not been sufficiently studied. In addition, anthropometric variables have been associated with pulmonary dysfunction, highlighting the waist-to-height ratio (WHtR). The aim was to evaluate the relationship between MetS and: lung age, anthropometric variables and the alteration of lung function. A cross-sectional study was carried out in 1901 workers, evaluating lung function through lung age (Morris & Temple equation) and spirometric values. The diagnosis of MetS was based on the harmonized criteria. We measured anthropometric variables (WHtR, waist circumference, body mass index, waist to hip ratio), blood pressure and biochemical variables (glucose, cholesterol total, HDL, triglycerides). Workers suffering from MetS showed an accelerated lung aging (59.4 ± 18.7 years vs 49 ± 18.4 years). The WHtR ≥ 0.55 was significantly related to an increase in lung age (β = 6.393, p < 0.001). In addition, a significant linear trend was found between clinical categories of WHtR and lung dysfunction, restrictive and mixed pattern. MetS caused an accelerated lung aging and favored the presence of restrictive lung impairment. In addition, WHtR ≥ 0.55 has been shown as the best predictor for pulmonary health.

Exploring the Spatial Patterning in Racial Differences in Cardiovascular Health Between Blacks and Whites Across the United States: The REGARDS Study

Background

Cardiovascular health (CVH) disparities between blacks and whites have persisted in the United States for some time, and although there have been remarkable improvements in addressing cardiovascular disease, it still remains the leading cause of death in the United States. In addition, well‐documented disparities are unfortunately widening incidence gaps across certain regions of the United States. Our focus was on answering the following questions: (1) How much spatial heterogeneity exists in the racial differences in CVH between blacks and whites across this country? and (2) Is the spatial heterogeneity in the racial differences significantly explained by living in the Stroke Belt?

Methods and Results

To explore the spatial patterning in the racial differences in CVH between blacks and whites across the country, we used geographically weighted regression methods, which result in local estimates of the racial differences in CVH. Using data from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) Study, we found significant spatial patterning in these racial differences, even beyond the well‐known Stroke Belt and Stroke Buckle. All of the estimated differences indicated blacks consistently having diminishing CVH compared with whites, where this difference was largely noted in pockets of the Stroke Belt and Stroke Buckle, in addition to moderate to large disparities noted in the Great Lakes region, portions of the Northeast, and along the West coast.

Conclusions

Efforts to improve CVH and ultimately reduce disparities between blacks and whites require culturally competent methods, with a strong focus on geography‐based interventions and policies.

The recalibrated HellenicSCORE based on newly derived risk factors from the Hellenic National Nutrition and Health Survey (HNNHS); the HellenicSCORE II

BACKGROUND

Because of the increased burden of cardiovascular disease (CVD), country specific risk prediction models to forecast future CVD events and mortality are recommended, for primary prevention. The aim of this study was to recalibrate the HellenicSCORE, to accurately estimate the 10-year risk CVD mortality of Greek adults.

METHODS

Data from the Hellenic National Nutrition and Health Survey (HNNHS) were used (N = 1012; 37.9% males). Information on age, smoking, systolic blood pressure (SBP), and total blood cholesterol from adults >40 years of age were derived following validated health survey protocols. Individual scores were calculated using these data and beta-coefficients derived from ESC SCORE.

RESULTS

Both updated HellenicSCORE II charts had lower risk estimates compared to the older version and were closer to the ESC SCORE charts, particularly at the extremes. No significant age difference by sex was observed (mean 59.5 (SD 13.1) years in total) in the population. Women had a significant higher mean total cholesterol compared to men [212.9 (39.5) vs 204.6 (41.2) mg/dl, respectively; p = 0.0343], but smoking prevalence and mean SBP was significantly higher in men [p for all, <0.001]. The mean population HellenicSCORE II score level was between 5.6% (0.2) and 7.9% (3.2) depending on the chart used, with no significant sex differences.

CONCLUSION

Although the HellenicSCORE II charts were lower, the mean population score was moderately high. This is of great importance because according to ESC guidelines, lifestyle intervention, and drug treatment should be based on an individuals' total cardiovascular risk.

The effect of egg consumption on cardiometabolic health outcomes: an umbrella review

OBJECTIVE

This umbrella review provides an overview of the consistency and gaps in the evidence base on eggs and cardiometabolic health.

DESIGN

PubMed, Web of Science, Cochrane Library, the Nutrition Evidence Systematic Review and Agency for Healthcare Research and Quality databases were screened for evidence-based reviews in English that assessed human studies on egg consumption and cardiometabolic outcomes.

RESULTS

Seven systematic reviews and fifteen meta-analyses were identified, with eighteen of these published since 2015. Overall, the systematic reviews were of low quality, while meta-analyses were of moderate- to high-quality. No association of increased egg intake and risks of heart disease or stroke in the general population were found in the meta-analyses. Increased risk of heart failure was noted in two meta-analyses that analysed the same three cohort studies. Five recent meta-analyses reported no increased risk of type 2 diabetes mellitus (T2DM) in the general population, although increased risk in US-based populations only has been reported. Older (<2013) meta-analyses reported increased risks of cardiovascular disease (CVD) or heart disease in T2DM populations, and no recent evidence-based reviews were identified. Finally, only one meta-analysis reported intervention studies specifically on eggs and biomarkers (i.e. lipids), and the results contradicted those from observation studies.

CONCLUSIONS

Recent evidence-based reviews conclude that increased egg consumption is not associated with CVD risk in the general population. More research is needed on the positive associations between egg consumption and heart failure and T2DM risk, as well as CVD risk in diabetics, before firm conclusions can be made.

Ten years risk assessment of atherosclerotic cardiovascular disease using Astro-CHARM and pooled cohort equation in a south Asian sub-population

BACKGROUND

Atherosclerotic cardiovascular diseases (ASCVD) are on the rise in low and middle-income countries attributed to modern sedentary lifestyle and dietary habits. This has led to the need of assessment of the burden of at-risk population so that prevention measures can be developed. The objective of this study was to assess ten years risk assessment of ASCVD using Astro-CHARM and Pooled Cohort Equation (PCE) in a South Asian sub-population.

METHODS

A total of 386 residents of all six districts of Karachi with no ASCVD were enrolled in the study through an exponential non-discriminative referral snowball sampling technique. The inclusion criteria consisted of age 40 years or above and either gender. Study participants were enrolled after obtaining informed written consent and those study participants who were found to have either congenital heart disease or valvular heart diseases or ischemic heart disease were excluded from the study based on initial screening. For the calculation of 10 years risk of ACVD based on Astro-CHARM and PCE, the variables were obtained including medical history and coronary artery calcium and C-reactive protein measurements.

RESULTS

Mean estimated 10-year risk of fatal or non-fatal myocardial infarction or stroke as per the Astro-CHARM was 13.98 ± 8.01%, while mean estimated 10-year risk of fatal or non-fatal myocardial infarction or stroke as per the PCE was 22.26 ± 14.01%. Based on Astro-CHARM, 11.14% of the study participants were labeled as having high risk, while PCE estimated 20.73% of study participants as having high risk of ASCVD.

CONCLUSION

Despite the fact that our findings showed substantial differences in ten-year risk of ASCVD between Astro-CHARM and PCE, both calculators can be used to develop a new population and specific risk estimators for this South Asian sub-population. Our study provides the first step towards developing a risk assessment guided decision-making protocol for primary prevention of ASCVD in this population.

Machine learning for predicting cardiac events: what does the future hold?

Introduction: With the increase in the number of patients with cardiovascular diseases, better risk-prediction models for cardiovascular events are needed. Statistical-based risk-prediction models for cardiovascular events (CVEs) are available, but they lack the ability to predict individual-level risk. Machine learning (ML) methods are especially equipped to handle complex data and provide accurate risk-prediction models at the individual level.Areas covered: In this review, the authors summarize the literature comparing the performance of machine learning methods to that of traditional, statistical-based models in predicting CVEs. They provide a brief summary of ML methods and then discuss risk-prediction models for CVEs such as major adverse cardiovascular events, heart failure and arrhythmias.Expert opinion: Current evidence supports the superiority of ML methods over statistical-based models in predicting CVEs. Statistical models are applicable at the population level and are subject to overfitting, while ML methods can provide an individualized risk level for CVEs. Further prospective research on ML-guided treatments to prevent CVEs is needed.

Environmentally responsive hydrogels for repair of cardiovascular tissue

Cardiovascular diseases (CVDs) pose a serious threat to human health, which are characterized by high disability and mortality rate globally such as myocardial infarction (MI), atherosclerosis, and heart failure. Although stem cells transplantation and growth factors therapy are promising, their low survival rate and loss at the site of injury are major obstacles to this therapy. Recently, the development of hydrogel scaffold materials provides a new way to solve this problem, which have shown the potential to treat CVD. Among these scaffold materials, environmentally responsive hydrogels have great prospects in repairing the microenvironment of cardiovascular tissues and vascular regeneration. They provide a new method for the treatment of cardiovascular tissue repair and space-time control for the release of various therapeutic drugs, including small-molecule drugs, growth factors, and stem cells. Herein, this article reviews the occurrence and current treatment of CVD, as well as the repair of cardiovascular injury by several environmental responsive hydrogels systems currently used, mainly focusing on the delivery of growth factors or the application of cell therapy to revascularization. In addition, we will also discuss the enormous potential and personal perspectives of environmentally responsive hydrogels in cardiovascular repair.

Pseudouridine and N-formylmethionine associate with left ventricular mass index: Metabolome-wide association analysis of cardiac remodeling

BACKGROUND

Heart failure (HF) is the fastest growing form of cardiovascular disease both nationally and globally, underlining a need to phenotype subclinical HF intermediaries to improve primary prevention.

OBJECTIVES

We aimed to identify novel metabolite associations with left ventricular (LV) remodeling, one upstream HF intermediary, among a community-based cohort of individuals.

METHODS

We examined 1052 Bogalusa Heart Study participants (34.98% African American, 57.41% female, aged 33.6-57.5 years). Measures of LV mass and relative wall thickness (RWT) were obtained using two-dimensional-guided echocardiographic measurements via validated eqs. LV mass was indexed to height^2.7 to calculate left ventricular mass index (LVMI). Untargeted metabolomic analysis of fasting serum samples was conducted. In combined and ethnicity-stratified analyses, multivariable linear and multinomial logistic regression models tested the associations of metabolites with the continuous LVMI and RWT and categorical LV geometry phenotypes, respectively, after adjusting for demographic and traditional cardiovascular disease risk factors.

RESULTS

Pseudouridine (B = 1.38; p = 3.20 × 10^-5) and N-formylmethionine (B = 1.65; 3.30 × 10^-6) were significantly associated with LVMI in the overall sample as well significant in Caucasians, with consistent effect direction and nominal significance (p < .05) in African Americans. Upon exclusion of individuals with self-report myocardial infarction or congestive HF, we similarly observed a 1.33 g/m^2.7 and 1.52 g/m^2.7 higher LVMI for each standard deviation increase in pseudouridine and N-formylmethionine, respectively. No significant associations were observed for metabolites with RWT or categorical LV remodeling outcomes.

CONCLUSIONS

The current analysis identified novel associations of pseudouridine and N-formylmethionine with LVMI, suggesting that mitochondrial-derived metabolites may serve as early biomarkers for LV remodeling and subclinical HF.

Advancing Healthcare Reform: The American Heart Association's 2020 Statement of Principles for Adequate, Accessible, and Affordable Health Care: A Presidential Advisory From the American Heart Association

The mission of the American Heart Association is to be a relentless force for a world of longer, healthier lives. The American Heart Association has consistently prioritized the needs and perspective of the patient in taking positions on healthcare reform while recognizing the importance of biomedical research, providers, and healthcare delivery systems in advancing the care of patients and the prevention of disease. The American Heart Association's vision for healthcare reform describes the foundational changes needed for the health system to serve the best interests of patients and to achieve health care and coverage that are adequate, accessible, and affordable for everyone living in the United States. The American Heart Association is committed to advancing the dialogue around healthcare reform and has prepared this updated statement of our principles, placed in the context of the advances in coverage and care that have occurred after the passage of the Affordable Care Act, the rapidly changing landscape of healthcare delivery systems, and our evolving recognition that efforts to prevent cardiovascular disease can have synergistic benefit in preventing other diseases and improving overall well-being. These updated principles focus on expanding access to affordable health care and coverage; enhancing the availability of evidence-based preventive services; eliminating disparities that limit the availability and equitable delivery of health care; strengthening the public health infrastructure to respond to social determinants of health; prioritizing and accelerating investments in biomedical research; and growing a diverse, culturally competent health and healthcare workforce prepared to meet the challenges of delivering high-value health care.

Religiosity and Excess Weight Among African-American Adolescents: The Jackson Heart KIDS Study

Recent studies suggest that religion and spirituality can yield health benefits for young African-Americans. We examined the relationship between religious practices, spirituality, and excess weight among African-American adolescents (N = 212) residing in the Deep South. Results from modified Poisson regression analysis indicate that adolescents who prayed daily had a lower prevalence of excess weight (PR 0.77 [95% CI 0.62-0.96]) than those who did not. This relationship was only significant for 12-15 year-old participants in age-stratified analysis. These findings suggest that preventive interventions offered to children and younger adolescents can have implications for weight status across the lifespan.

Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals.

RESULTS

Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Exosome and Biomimetic Nanoparticle Therapies for Cardiac Regenerative Medicine

Exosomes and biomimetic nanoparticles have great potential to develop into a wide-scale therapeutic platform within the regenerative medicine industry. Exosomes, a subgroup of EVs with diameter ranging from 30-100 nm, have recently gained attention as an innovative approach for the treatment of various diseases, including heart disease. Their beneficial factors and regenerative properties can be contrasted with various cell types. Various biomimetic nanoparticles have also emerged as a unique platform in regenerative medicine. Biomimetic nanoparticles are a drug delivery platform, which have the ability to contain both biological and fabricated components to improve therapeutic efficiency and targeting. The novelty of these platforms holds promise for future clinical translation upon further investigation. In order for both exosome therapeutics and biomimetic nanoparticles to translate into large-scale clinical treatment, numerous factors must first be considered and improved. Standardization of different protocols, from exosome isolation to storage conditions, must be optimized to ensure batches are pure. Standardization is also important to ensure no variability in this process across studies, thus making it easier to interpret data across different disease models and treatments. Expansion of clinical trials incorporating both biomimetic nanoparticles and exosomes will require a standardization of fabrication and isolation techniques, as well as stricter regulations to ensure reproducibility across various studies and disease models. This review will summarize current research on exosome therapeutics and the application of biomimetic nanoparticles in cardiac regenerative medicine, as well as applications for exosome expansion and delivery on a large clinical scale.

Trajectories of posttraumatic stress in patients with confirmed and rule-out acute coronary syndrome

Many patients evaluated in the emergency department (ED) for acute coronary syndrome (ACS) develop posttraumatic stress symptoms (PTSS), but little is known about symptom trajectories over time. We estimated longitudinal trajectories of PTSS from ED to 1 year after evaluation for suspected ACS (N = 1000), and the effect of threat perceptions and discharge diagnosis. Participants reported on threat perceptions in the ED, ongoing cardiac threat at 1 month, and PTSS at 1, 6, and 12 months. Latent growth mixture modeling identified 3 PTSS trajectories over 1 year: Resilient (81.75%), Chronic-Worsening (13.69%), and Acute-Recovering (4.56%). Chronic-Worsening and Acute-Recovering classes reported significantly higher ED and cardiac threat perceptions than Resilient class. Discharge diagnosis did not differ (χ²(2) = 2.93, p = .231). PTSS are common following evaluation for suspected ACS, and trajectories vary, but targeting threat perceptions may reduce PTSS and improve clinical course, whether or not patients are ultimately diagnosed with ACS.

Association of the mean platelet volume and red cell distribution width with dipper and non-dipper blood pressure in prehypertensive non-smokers

OBJECTIVE

Absence of nocturnal blood pressure (BP) dipping is associated with poor health outcomes, including increased mortality. Non-dipper BP seems to be a predictor of cardiovascular damage in hypertensive patients. The aim of this study was to investigate the association of the mean platelet volume (MPV) and red cell distribution width (RDW) with nocturnal dipping/non dipping status in newly diagnosed and untreated prehypertensive non-smokers, using ambulatory BP monitoring.

RESULTS

Twenty-eight patients (15 males) in the dipper group and 24 patients (11 males) in the non-dipper group were evaluated in this study. The age of patients was 41.64 ± 15.01 and 37.96 ± 15.08 years in the dipper and non-dipper groups, respectively. The rate of nocturnal systolic BP drop in the dipper and non-dipper groups was 13.79 ± 3.35% (10.20-22.10) and 5.96 ± 2.87% (1.10-9.30) (P < 0.001), respectively. Also, the mean rate of nocturnal diastolic BP drop in the dipper and non-dipper groups was 17.02 ± 5.09% (10.30-26.90) and 6.19 ± 2.75% (1.20-9.70) (P < 0.001), respectively. RDW and MPV were significantly higher in non-dipper patients than dipper patients (P = 0.001 and P = 0.012, respectively). Bivariate analysis revealed that MPV was inversely correlated with the nocturnal systolic BP drop (P = 0.005, r = - 0.385). Furthermore, RDW was inversely correlated with systolic BP drop (P = 0.019, r = - 0.324).

Epigenetic Modifications in T Cells: The Role of DNA Methylation in Salt-Sensitive Hypertension

The SS (Dahl salt sensitive) rat is an established model of hypertension and renal damage that is accompanied with immune system activation in response to a high-salt diet. Investigations into the effects of sodium-independent and dependent components of the diet were shown to affect the disease phenotype with SS/MCW (JrHsdMcwi) rats maintained on a purified diet (AIN-76A) presenting with a more severe phenotype relative to grain-fed SS/CRL (JrHsdMcwiCrl) rats. Since contributions of the immune system, environment, and diet are documented to alter this phenotype, this present study examined the epigenetic profile of T cells isolated from the periphery and the kidney from these colonies. T cells isolated from kidneys of the 2 colonies revealed that transcriptomic and functional differences may contribute to the susceptibility of hypertension and renal damage. In response to high-salt challenge, the methylome of T cells isolated from the kidney of SS/MCW exhibit a significant increase in differentially methylated regions with a preference for hypermethylation compared with the SS/CRL kidney T cells. Circulating T cells exhibited similar methylation profiles between colonies. Utilizing transcriptomic data from T cells isolated from the same animals upon which the DNA methylation analysis was performed, a predominant negative correlation was observed between gene expression and DNA methylation in all groups. Lastly, inhibition of DNA methyltransferases blunted salt-induced hypertension and renal damage in the SS/MCW rats providing a functional role for methylation. This study demonstrated the influence of epigenetic modifications to immune cell function, highlighting the need for further investigations.

Call to Action: Urgent Challenges in Cardiovascular Disease: A Presidential Advisory From the American Heart Association

Although advances in care have spurred improvements in cardiovascular outcomes, cardiovascular disease remains the leading cause of death in the United States and around the world. Previous declines in cardiovascular disease mortality have slowed and even reversed for certain demographics. Further concerns exist with regard to cardiovascular drug innovation, quality of care, and healthcare costs. The Value in Healthcare Initiative-Transforming Cardiovascular Care, a collaboration of the American Heart Association and Duke University, Robert J. Margolis, MD, Center for Health Policy, aims to increase access to and affordability of cardiovascular treatment and to decrease barriers to care. The following Call to Action describes trends in cardiovascular care, identifies gaps in areas of cardiovascular disease prevention and treatment, highlights challenges with medical product innovation, and finally, outlines a series of learning collaboratives that will aid in the development of road maps for transforming cardiovascular care.

Association of Cardiovascular Disease With Premature Mortality in the United States

Importance

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in the United States. Despite substantial declines in CVD mortality rates during past decades, progress against cardiovascular deaths in midlife has stagnated, with rates increased in some US racial/ethnic groups.

Objective

To examine the trends in premature (ages 25-64 years) mortality from CVD from 2000 to 2015 by demographics and county-level factors, including education, rurality, and the prevalence of smoking, obesity, and diabetes.

Design, Setting, and Participants

This descriptive study used US national mortality data from the Surveillance, Epidemiology, and End Results data set and included all CVD deaths among individuals ages 25 to 64 years from January 2000 to December 2015. The data analysis began in February 2018.

Exposures

Age, sex, race/ethnicity, and county-level factors.

Main Outcomes and Measures

Age-standardized mortality rates and average annual percent change (AAPC) in rates by age, sex, race/ethnicity, and county-level factors (in quintiles) and relative risks of CVD mortality across quintiles of each county-level factor.

Results

In 2000 to 2015, 2.3 million CVD deaths occurred among individuals age 25 to 64 years in the United States. There were significant declines in CVD mortality for black, Latinx, and Asian and Pacific Islander individuals (AAPC: range, -1.7 to -3.2%), although black people continued to have the highest CVD mortality rates. Mortality rates were second highest for American Indian/Alaskan Native individuals and increased significantly among those aged 25 to 49 years (AAPC: women, 2.1%; men, 1.3%). For white individuals, mortality rates plateaued among women age 25 to 49 years (AAPC, 0.05%). Declines in mortality rates were observed for most major CVD subtypes except for ischemic heart disease, which was stable in white women and increased in American Indian/Alaska Native women, hypertensive heart disease, for which significant increases in rates were observed in most racial/ethnic groups, and endocarditis, for which rates increased in white individuals and American Indian/Alaska Native men. Counties with the highest prevalence of diabetes (quintile 5 vs quintile 1: relative risk range 1.6-1.8 for white individuals and 1.4-1.6 for black individuals) had the most risk of CVD mortality.

Conclusions and Relevance

There have been substantial declines in premature CVD mortality in much of the US population. However, increases in CVD mortality before age 50 years among American Indian/Alaska Native individuals, flattening rates in white people, and overall increases in deaths from hypertensive disease suggest that targeted public health interventions are needed to prevent these premature deaths.

Effect of Dietary Insulinemia on All-Cause and Cause-Specific Mortality: Results From a Cohort Study

Background: Insulin response to diet might predict the risk of mortality; however, the evidence is limited. We prospectively evaluated the link between the dietary hyperinsulinemia index (DHI) and dietary insulin resistance index (DIRI) with all-cause and cause-specific (cardiovascular disease [CVD] and cancer) mortality.Methods: The National Health and Nutrition Examination Survey (1999-2010) database was used. Vital status through December 31, 2011, was ascertained. Stepwise linear regression models consisted of 39 macro/micronutrients applied, and fasting plasma C-peptide for the DHI and triglyceride/high-density lipoprotein cholesterol ratio (TG/HDL-C) for the DIRI were used. Adjusted Cox regression (followed by propensity score matching) was performed to determine the hazard ratios (HRs) and 95% confidence interval (95% CIs).Results: Overall, 22,246 participants were included (mean age = 47.8 years; 48.9% men). There was a significant increasing risk of mortality across the quartiles of DHI, i.e., participants with a highest score of DHI (Q4) had a greater risk of all-cause (HR: 1.21, 95% CI: 1.17-1.26), CVD (HR: 1.17, 95% CI: 1.07-1.29), and cancer (HR: 1.15, 95% CI: 1.08-1.23) mortality compared with the first quartile (Q1; p < 0.001 for all comparisons). Similarly, participants in the highest DIRI quartile (Q4) had 23% and 31% higher risk of all-cause and CVD mortality, respectively, compared with Q1, while the association between cancer mortality and DIRI was non-significant (HR: 0.88, 95% CI: 0.35-2.61).Conclusions: These findings highlight, for the first time, the detrimental role (association) of insulinemia and insulin resistance potential of diet on all-cause and cause-specific mortality. Our findings support the role of C-peptide and TG/HDL-C ratio as cost-effective and practical biomarkers in clinical settings. These results need to be confirmed to establish their implications.

The Role of Oxidative Stress in Common Risk Factors and Mechanisms of Cardio-Cerebrovascular Ischemia and Depression

The public health sector faces a huge challenge as a result of the high prevalence and burden of disability caused by ischemic cardio-cerebrovascular disease (CVD) and depression. Although studies have explored the underlying mechanisms and potential therapies to address conditions, there is no treatment breakthrough, especially for depression which is highly influenced by social stressors. However, accumulating evidence reveals that CVD and depression are correlated and share common risk factors, particularly obesity, diabetes, and hypertension. They also share common mechanisms, including oxidative stress (OS), inflammation and immune response, cell death signaling pathway, and microbiome-gut-brain axis. This review summarizes the relationship between ischemic CVD and depression and describes the interactions among common risk factors and mechanisms for these two diseases. In addition, we propose that OS mediates the crosstalk between these diseases. We also reveal the potential of antioxidants to ameliorate OS-related injuries.

Evaluating the potential of Special Olympics fitness models as a health intervention for adults with intellectual disabilities

BACKGROUND

People with intellectual disabilities (ID) have high prevalence of cardiovascular disease (CVD) risk factors; yet, few behavioral health interventions are designed and implemented for people with ID.

OBJECTIVE

This study examined Special Olympics Inc. (SOI) fitness models as a potential intervention to reduce CVD risk in people with ID.

METHODS

Data from SOI fitness models implemented in 2016-2018 were assessed. Special Olympics Programs received funding, resources, and technical assistance from SOI to conduct fitness models centered on inclusive physical activity and goal setting. Weight, body mass index, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured at baseline and 4-12 weeks into the model. Multi-level multivariable quintile linear regression assessed change.

RESULTS

383 participants with ID (athletes) and 281 partners without ID met inclusion criteria. Mean weight loss among athletes was 0.67 kg and 132 (31.9%) lost ≥ 1 kg. Blood pressure decreased in SBP quintile 4 (-7.52 mm Hg, 95% confidence interval [CI]: 11.8, -4.0), SBP quintile 5 (-9.52 mm Hg, 95% CI: 13.5, -5.6), and DBP quintile 5 (-7.49 mm Hg, 95% CI: 13.1, -1.9). Partners had similar results. Strongest effects were in a 'high-risk' group that was in the quintile 4 or 5 in all baseline measures.

CONCLUSION

In fitness models developed to improve fitness for people with ID, there was a reduction in weight and blood pressure. SOI fitness models show promise and potential as a health intervention. This work enables further examination of indicators for successful implementation and evaluation of health.

Prospective associations of cardiovascular disease with physical performance and disability : A longitudinal cohort study in the Osteoarthritis Initiative

BACKGROUND

Literature regarding cardiovascular disease (CVD) and incident physical performance limitations and disability in older people is equivocal.

AIMS

This study aimed to investigate whether CVD is longitudinally associated with incident physical performance limitations and disability in a large population-based sample.

METHODS

This was an 8‑year prospective study using data collected as part of the Osteoarthritis Initiative. Participants were community-dwelling adults with knee osteoarthritis or at high risk for this condition. Diagnosed CVD was self-reported. Physical performance was assessed with measures of chair stand time and gait speed, whereas disability was assessed with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Longitudinal associations between CVD and changes in physical performance tests (chair stand time and gait speed) and disability score were analyzed using generalized linear models with repeated measurements.

RESULTS

The analyzed sample comprised 4796 adults (mean age 61.2 years, 58.5% female), of whom 313 people (6.5%) reported CVD at baseline. During 8 years of follow-up, after adjustment for 11 potential confounders measured at baseline, those with CVD experienced a worse profile in chair stand time over the 8‑year follow-up period than those without CVD (p = 0.006).

CONCLUSION

In a cohort of middle-aged and older adults with knee osteoarthritis or at high risk for this condition those with CVD experienced a worse profile in chair stand time over the 8‑year follow-up period than those without CVD; however, CVD was not significantly associated with an increased incidence of poor gait speed and disability over 8 years of follow-up. Importantly, no associations were observed when utilizing propensity score matching.

Health Equity and Implementation Science in Heart, Lung, Blood, and Sleep-Related Research: Emerging Themes From the 2018 Saunders-Watkins Leadership Workshop

Disparities in health outcomes for heart, lung, blood, and sleep-related health conditions are pervasive in the United States, with an unequal burden experienced among structurally disadvantaged populations. One reason for this disparity is that despite the existence of effective interventions that promote health equity, few have been translated and implemented consistently in the healthcare system. To achieve health equity, there is a dire need to implement and disseminate effective evidence-based interventions that account for the complex and multilayered social determinants of health among marginalized groups across healthcare settings. To that end, the National Heart, Lung, and Blood Institute's Center for Translation Research and Implementation Science invited early stage investigators to participate in the inaugural Saunders-Watkins Leadership Workshop in May of 2018 at the National Institutes of Health. The goals of the workshop were to: (1) present an overview of health equity research, including areas which require ongoing investigation; (2) review how the fields of health equity and implementation science are related; (3) demonstrate how implementation science could be utilized to advance health equity; and (4) foster early stage investigator career success in heart, lung, blood, and sleep-related research. Herein, we highlight key themes from the 2-day workshop and offer recommendations for the future direction of health equity and implementation science research in the context of heart, lung, blood, and sleep-related health conditions.

Future of Personalized Cardiovascular Medicine: JACC State-of-the-Art Review

Previous decades have seen significant progress in the biological understanding of cardiovascular disease, as well as major advances in computational and information technologies. However, anticipated improvements in outcomes, quality, and cost of cardiovascular medicine at the individual and population levels from these advances have lagged expectations. Further, trends showing widening gaps in the pace of technological development and its successful uptake and application in practice suggests that substantial systemic changes are needed. Recent declines in key U.S. health outcomes have added further urgency to seek scalable approaches that deliver the right treatment to the right patient and to develop information-driven policies that improve health. The clinical care and research enterprises are currently in the midst of assimilating changes entrained by a "fourth industrial revolution" marked by the convergence of biology, physical sciences, and information science. These changes, if managed appropriately, can simultaneously enable cost-effective personalized medical care as well as more effective and targeted population health interventions. In this paper derived from a lecture in honor of cardiologist Paul Dudley White, the author explores how White's prescient insights into prevention and treatment continue to resonate today as we seek to assimilate ubiquitous computing, sophisticated sensor technologies, and bidirectional digital communication into the practice of cardiology. How the ongoing acceleration in basic science and information technologies can be wedded to the principles articulated by White as we pursue scalable approaches to personalized medicine is also examined.

Aspirin Eugenol Ester Reduces H2O2-Induced Oxidative Stress of HUVECs via Mitochondria-Lysosome Axis

The oxidative stress of vessel endothelium is a major risk factor of cardiovascular disorders. Antioxidative stress drugs are widely used in cardiovascular therapy. Aspirin eugenol ester (AEE) is a new pharmaceutical compound synthesized by esterification reaction of aspirin with eugenols and possesses antioxidative activity. The present study was designed to investigate the mechanism how AEE protects human umbilical vein endothelial cells (HUVECs) from H₂O₂-induced oxidative stress. H₂O₂ was given to the HUVECs with or without AEE pretreatment. Changes in the oxidative stress-related factors, including those related to the mitochondria-lysosome axis, were determined with Western blotting, cellular immunofluorescence, and enzyme activity test. The results showed that, in the HUVECs, 300 μM H₂O₂ treatment significantly increased the apoptosis rate, MDA concentration, reactive oxygen species (ROS) production, mitochondrial membrane potential, expression of Bax and mature cathepsin D (CTSD), and activity of CTSD and Caspase3 (Cas3) but decreased the expression of Bcl2 and lysosomal membrane stability, while in the HUVECs pretreated with AEE, the above changes caused by either the stimulatory or the inhibitory effect of H₂O₂ on the relevant factors were significantly reduced. AEE pretreatment significantly enhanced the activity of cellular superoxide dismutase and glutathione peroxidase in the HUVECs. Our findings suggest that AEE effectively reduced H₂O₂-induced oxidative stress in the HUVECs via mitochondria-lysosome axis.
