Acute impact of inorganic nitrate supplementation after ischemia and during small muscle mass exercise in postmenopausal females: A pilot study.

Menopause is associated with reduced endothelial-dependent vasodilation and increased cardiovascular disease (CVD) risk. Dietary nitrate, a non-pharmacological approach, may increase vasodilatory capacity consequentially reducing CVD risk. We investigated macro- and microvascular function after acute nitrate supplementation in postmenopausal females (PMF). Vascular function was studied with flow-mediated vasodilation (FMD) and near-infrared post occlusive reactive hyperemia (PORH). Incremental handgrip exercise was performed to investigate blood flow and tissue oxygenation. We hypothesized acute dietary nitrate would not impact resting endothelial measures but would increase post ischemic vasodilation and incremental exercise blood flow. Late-phase PMF (n = 12) participated in a randomized crossover design with 140 mL of nitrate-rich (NR) beetroot juice or nitrate-poor black currant juice. Testing included a 5-min FMD, a 3-min ischemic exercise FMD, and incremental exercise at 10%, 15%, and 20% maximal voluntary contraction to measure blood flow and pressure responses. A p ≤ 0.05 was considered significant. One-way ANOVA indicated lower resting pressures, but no change to FMD, or PORH in either protocol. Two-way repeated measures ANOVA indicated NR supplementation significantly reduced mean arterial pressure at rest and during incremental exercise at all intensities without changes to blood flow. Acute nitrate is effective for resting and exercising blood pressure management in PMF.

Accuracy of self-perceived cardiovascular disease risk and factors predicting risk underestimation in perimenopausal and postmenopausal women in Ismailia, Egypt.

Cardiovascular disease (CVD) is the leading cause of death globally, with women at higher risk after menopause. This increased risk is attributed to both aging and hormonal changes. Prior research has established a link between CVD risk perception and adopting healthy behaviors to prevent CVD. This study aimed to assess the accuracy of self-perceived CVD risk in perimenopausal and postmenopausal women, and to identify factors that predict CVD risk underestimation among them. A cross-sectional study was conducted in the administrative sectors of Suez Canal University campus in Ismailia, Egypt, over a period of eight months starting in July 2022. A total of 390 eligible women (employees and workers) were randomly selected. Participants were interviewed to obtain data on demographics, medical history, self-perceived risk of CVD, self-perceived general health, awareness of factors that increase the risk of developing CVD, perceived stress, health literacy, numeracy, and self-perceived 10-year risk of developing major cardiovascular events. They also underwent measurements of blood pressure, weight, and height. The updated 2019 WHO/CVD risk non-laboratory-based prediction chart for the North Africa and Middle East Region was used to predict the 10-year risk of major cardiovascular events for the study participants. Risk accuracy was measured by comparing self-perceived CVD risk with predicted CVD risk. The ratio of self-perceived to predicted moderate/high CVD risk was 27.7% to 44.3%, respectively. The accuracy of CVD risk perception was 68.2%. Kappa analysis results showed fair and significant agreement between self-perceived and predicted CVD risk (kappa ± SE = 35.9 ± 4.1%, p < 0 .001). The proportion of women who underestimated their risks was 24.1%. Of those in the high-risk group, 93.3% underestimated their CVD risk, compared to 50.6% in the moderate-risk group. Factors that significantly predicted CVD risk underestimation included being married (aOR 14.5; 95% CI 1.4-149.9), low income (aOR 2.321; 95% CI 1.09-4.909), high BMI (aOR 4.78; 95% CI 1.9-11.9), hypertension (aOR 3.5; 95% CI 2-6.2), and old age (aOR 1.46; 95% CI 1.3-1.6). Approximately one-third of our study participants misperceived their CVD risk; of those who did, 75.8% underestimated it. Marital status, old age, low income, high BMI, and hypertension strongly predicted CVD risk underestimation. These findings identified the menopausal women subgroups that could benefit from targeted health interventions designed to reduce CVD risk underestimation and improve risk accuracy.

Metabolic syndrome clustering patterns and the association with cardiovascular disease among post-menopausal Korean women

The metabolic syndrome (MetS) is a group of diseases conceptualized as a clustering of risk factors, with the risks of developing MetS in women varying significantly before and after menopause. This study investigated MetS clustering patterns and their association with cardiovascular disease (CVD) risk among post-menopausal women (n = 2479) using data from the Korean Genome Epidemiology Study. Using latent class analysis, three groups emerged: diabetic (5.6%), hypertensive (35.2%), and low-risk (59.2%). Relative to the low-risk group, the diabetic group demonstrated associations with older age, a family history of chronic disease, an increased Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), an elevated white blood cell (WBC) count, experience with hysterectomy, being a non-drinker, more physical activity, and excessive sleep. The hypertensive group was associated with older age, lower monthly income, a family history of chronic disease, increased HOMA-IR, a higher WBC count, more physical activity, and excessive sleep. The diabetic and hypertensive groups had a significantly higher CVD risk than the low-risk group (diabetic: odds ratio [OR] = 2.41 [1.11, 5.27]; hypertensive: OR = 2.46 [1.33, 4.55]). This study identified potential markers for MetS screening in post-menopausal women, highlighting the need for early intervention and personalized healthcare for middle-aged women to reduce CVD risk following menopause.

Prevalence and perspective directions for correction of behavioral risk factors of cardiovascular diseases associated with unhealthy diet and low physical activity in young people

Cardiovascular diseases (CVD) are the leading cause of death worldwide. According to statistics from the American Heart Association (AHA), the prevalence of CVD among young people aged 20–39 years varies: 14.2% men, 9.7% women. Behavioral risk factors for CVD, in other words those related to lifestyle, include sedentary lifestyle, smoking, alcohol consumption, unhealthy diet, overweight and obesity, and depression. These risk factors are modifiable and therefore there is great potential for reducing CVD risk through primary or secondary prevention. Young people are the most perspective group for primary prevention, since young people may be more susceptible to information influence. In addition to young people's awareness of CVD risk factors, the initial level of young people's readiness to make lifestyle changes plays a key role in reducing the risk of developing CVD.

Well-Being and Cardiovascular Health: Insights From the UK Biobank Study.

Cardiovascular diseases (CVDs) are a leading global health concern. Emerging evidence suggests a potential protective role of well-being in reducing CVD risk. We conducted a cohort analysis using the UK Biobank data set, encompassing 121 317 participants. We assessed the well-being of participants using a well-being index derived from baseline questionnaires. Well-being categories were derived by latent class analysis using general happiness and satisfaction with family, friendships, health, and finance situations. The relationship between well-being and 4 major CVDs was analyzed using Cox proportional hazards models and Mendelian randomization. The study also examined the impacts of well-being on lifestyle factors and inflammatory markers, and its mediating role in the well-being-CVD relationship. Higher well-being was associated with a significantly reduced risk of various CVDs. Latent class analysis identified 4 distinct well-being groups (low, variable, moderate-to-high, and high satisfaction), with higher satisfaction levels generally associated with lower risk of CVDs. Mendelian randomization suggested potential causal relationships between well-being and reduced risk of CVDs. Participants with greater well-being demonstrated healthier behaviors and lower levels of inflammatory markers. Mediation analysis indicated that lifestyle and inflammatory markers partially mediated the relationship between well-being and CVDs. This study demonstrates a robust inverse association between well-being and the risks of CVDs, suggesting that enhancing well-being may be a viable strategy for CVD prevention. The role of lifestyle factors and inflammation as a mediator provides insight into possible biological pathways linking psychological states and cardiovascular health.

Metabolic revitalization: exploring erythrocyte fatty acid profile following laparoscopic sleeve gastrectomy.

Obesity is linked to metabolic disorders. Bariatric surgery offers a promising therapeutic approach, but its impact on fatty acid (FA) profiles within erythrocytes and the associated clinical implications remain underexplored. This study aimed to assess changes in erythrocytes' membranes FA after Laparoscopic Sleeve Gastrectomy (LSG) and to correlate these alterations with clinical parameters. Sixty-one patients with morbid obesity undergoing LSG and 32 healthy controls were enrolled. Erythrocytes' membranes FA were analyzed using gas chromatography. Clinical parameters were assessed, including BMI, blood pressure, and multiple biochemistry markers. Bariatric intervention reduced BMI (41.1 to 32.0) and fat mass (54.1 to 35.2kg). Also, other anthropometric parameters improved significantly. Favorable changes in FA metabolism post LSG, potentially leading to a reduction in cardiovascular disease (CVD) risk, were observed. The OMEGA-3 Index (1.8 vs 3.0), and the eicosapentaenoic/arachidonic (0.1 vs 0.2) FA ratio increased after surgery. The dynamics of metabolism post-LSG, assessed by exploring the ratios of erythrocytes' FA concentration in baseline and 6 months after the surgery, with the corresponding ratios calculated for clinical parameters, evidenced the impact of linoleic (LA) on obesity reduction. The LA ratios increased along with the reduction of BMI (r=-0.32), fat mass (r=-0.39), and waist circumference (r=-0.33) proportions. The opposite relations of LA were held with Excess Weight Loss percentage (r=0.49), and Excess BMI Loss percentage (r=0.5). The study underscores distinct post-LSG changes in erythrocytes' FA profiles potentially associated with reduced weight and BMI, improved inflammatory status, and lowered CVD risk.

Effect of depression treatment on health behaviors and cardiovascular risk factors in primary care patients with depression and elevated cardiovascular risk: data from the eIMPACT trial.

Depression is an independent risk factor for cardiovascular disease (CVD), but it is unknown if successful depression treatment reduces CVD risk. Using eIMPACT trial data, we examined the effect of modernized collaborative care for depression on indicators of CVD risk. A total of 216 primary care patients with depression and elevated CVD risk were randomized to 12 months of the eIMPACT intervention (internet cognitive-behavioral therapy [CBT], telephonic CBT, and select antidepressant medications) or usual primary care. CVD-relevant health behaviors (self-reported CVD prevention medication adherence, sedentary behavior, and sleep quality) and traditional CVD risk factors (blood pressure and lipid fractions) were assessed over 12 months. Incident CVD events were tracked over four years using a statewide health information exchange. The intervention group exhibited greater improvement in depressive symptoms (p < 0.01) and sleep quality (p < 0.01) than the usual care group, but there was no intervention effect on systolic blood pressure (p = 0.36), low-density lipoprotein cholesterol (p = 0.38), high-density lipoprotein cholesterol (p = 0.79), triglycerides (p = 0.76), CVD prevention medication adherence (p = 0.64), or sedentary behavior (p = 0.57). There was an intervention effect on diastolic blood pressure that favored the usual care group (p = 0.02). The likelihood of an incident CVD event did not differ between the intervention (13/107, 12.1%) and usual care (9/109, 8.3%) groups (p = 0.39). Successful depression treatment alone is not sufficient to lower the heightened CVD risk of people with depression. Alternative approaches are needed. ClinicalTrials.gov Identifier: NCT02458690.

P206 ANALYZING ATTRITION POINTS IN INDONESIA'S HYPERTENSION CARE CASCADE: STUDY OF 200,000 POPULATION FROM 2013-2018

Background: According to NCDRisC, Indonesia ranks as the worst performer globally in hypertension control, with control rates of 5.1% for females and 3.6% for males, despite having an income level with better potential outcomes. Hypertension is a leading risk factor for cardiovascular disease (CVD), and its management is critical for reducing major CVD risks. This study aims to identify the significant attrition points in the hypertension care cascade in Indonesia, focusing on identifying where the most significant drop-offs occur at each stage. Methods: The study utilizes data from the 2018 Indonesian Basic Health Research (RISKESDAS), a nationally representative health survey sample of ∼1 million individuals. The hypertension care cascade was divided into stages: prevalence, diagnosis, treatment, and control. Descriptive statistics and attrition analysis were used to analyze the data. Results: Indonesia managed to diagnose 29.6% of its hypertensive population and treat 23.4%, yet only 4.4% achieved control over their condition. Between 2013 and 2018, diagnosis rates slightly decreased from 33.5% to 29.6%, while treatment rates significantly improved, doubling from 10.7% to 23.4%. Control rates modestly improved by ∼60% from 2013 to 2018, from 2.6% to 4.4%. The diagnostic phase showed the highest attrition, with over 70% of the hypertensive population undiagnosed. Improvement in diagnosed-to-treated performance was observed, with conversion rates increasing from 32% in 2013 to 79% in 2018. However, the treatment-to-control conversion remained low at 18%, indicating that 19% of the treated hypertensive population did not achieve control. Huge care gaps are shown in males vs females (Figure 1). Overall, more than 95% of the hypertensive population remains uncontrolled. Conclusion: The most significant drop in the hypertension care cascade occurs at the diagnostic phase, where over 70% of the hypertensive population remains undiagnosed. Despite improvements in treatment rates, the conversion from treatment to control remains low. Addressing the diagnostic gap is critical for enhancing hypertension control and reducing CVD risks in Indonesia.

Unraveling tea and coffee consumption effects on cardiovascular diseases risk factors: A narrative review.

Daily lifestyle plays a vital role in modifying the risk for cardiovascular diseases (CVDs). Our daily life isn't inseparable from nutrition intake. As such, tea and coffee are often regarded as the most consumed beverages worldwide. There have been a lot of debates on the adverse effects and benefits of consuming these popular beverages. This comprehensive review explores the different types of tea and coffee and their mechanism of action. It delves deeper into their roles in reducing CVD risk, aiding CVD recovery, lowering CVD mortality, and their varying effects across populations and regions. An extensive literature search was conducted on PubMed. Relevant articles were identified through cross-referencing and manual searches. Excluded from the study were commentaries, case reports, clinical vignettes, and non-English articles. Tea and coffee contain varying levels of caffeine and other bioactive compounds with cardioprotective effects against oxidative stress, inflammation, and more. Genetic factors further modulate their effects. Tea flavonoids benefit cholesterol, blood pressure, and endothelial function, while coffee constituents impact oxidative stress, metabolism, insulin sensitivity, and gut flora. Moderate consumption of both beverages may offer cardiovascular benefits, but outcomes vary depending on populations and conditions. Tea and coffee consumption may influence CVD recovery by reducing mortality and improving survival, however, it must be noted that it has the potential to be harmful to some individuals. Evidence suggests that moderate consumption of these beverages may be linked to reduced cardiovascular mortality, although individual characteristics and pre-existing conditions can influence outcomes. Excessive caffeine consumption, found in both beverages, may pose risks such as arrhythmias, hypertension, and cardiovascular mortality in CVD patients, with a dose-dependent nature. Future research should delve into mechanisms, genetic factors, and diverse cultural impacts of its use. Health care providers should consider individual characteristics when advising on tea and coffee consumption in the context of cardiovascular health.

Circulating CD31+ Angiogenic T cells are reduced in prediabetes and increase with exercise training

AimsTo investigate circulating angiogenic cells in adults with prediabetes and the effect of a structured exercise program. MethodsA cohort of adults with overweight/obesity and either normal glucose (NG) or prediabetes were randomised to receive exercise (Exercise) (as twice weekly supervised combined high intensity aerobic exercise and progressive resistance training, and once weekly home-based aerobic exercise) or an unsupervised stretching intervention (Control) for 12 weeks. Circulating angiogenic T cells, muscle strength, and cardiovascular disease risk factors, including blood lipids, arterial stiffness, central haemodynamic responses, and cardiorespiratory fitness (VO2peak) in those with prediabetes (n = 35, 16 Control, 19 Exercise) and NG (n = 37, 17 Control, 20 Exercise) were analysed at baseline and after the 12-week intervention. ResultsAt baseline, compared with NG those with prediabetes demonstrated reduced VO2peak, angiogenic CD31+CD8+ T cells and VEGFR2+CD4+ T cells, and increased systolic blood pressure. CD31+ T cells were negatively correlated with cardiovascular disease (CVD) risk. Compared with Control, exercise training increased muscle strength, VO2peak, and CD31+CD4+ and CD31+CD8+ T cells in NG and prediabetes. ConclusionsCirculating angiogenic CD31+ T cells are decreased in people with prediabetes and are enhanced with exercise training. Exercise increases CD31+ T cells, and through this mechanism it is proposed that it may reduce CVD risk.

P203 IMPACT OF IMPLEMENTING A COMMUNITY CARE STRATEGY TO REDUCE THE RISK OF CARDIOVASCULAR DISEASE IN SANTANDER, COLOMBIA: PRELIMINARY RESULTS OF THE RE-HOPE STUDY

Background: Hypertension is the main risk factor of cardiovascular disease (CVD), affecting 1.28 billion adults and resulting in 1.16 million deaths. In Colombia, hypertension affected 7.8 million adults in 2019. Different sociocultural and health system-related barriers may interfere with hypertension management. Our aim was to determine the preliminary impact of this community-based strategy on the changes in hypertension control in Colombia. Methods The Re-Hope study is a community-based strategy to reduce CVD risk in 13 municipalities of Santander, Colombia. Nursing assistants referred patients to the cardiovascular risk program (CVRP), facilitated medical appointments, and provided health counseling. A longitudinal analysis was conducted on data from the first three follow-up visits. Included were adults &gt;18 years with hypertension not enrolled in the CVRP. Standardized questionnaires gathered sociodemographic, medication, and lifestyle data. Anthropometric and blood pressure measurements were taken. Hypertension was defined as systolic BP &gt;140 mmHg, diastolic BP &gt;90 mmHg, self-reported hypertension, or antihypertensive medication use. Pharmacological adherence was assessed with the Morisky 4-item scale. Tobacco and alcohol use were categorized as never or current consumers. Blood pressure changes were evaluated with a paired t-test, and categorical variable changes with McNemar and Stuart-Maxwell tests. Analysis was done using Stata software. Results A total of 2,585 participants were included. The mean age was 65.1 years (SD 11.9) and 64.3% were women. After 6 months of follow-up, the mean systolic and diastolic blood pressure reduced 17.03 mmHg (SD 17.95) and 7.04 mmHg (SD 11.22), respectively. Hypertension control increased on 11.7%. Antihypertensive combination therapy increased by 4.4% for dual therapy and 4.6% for triple therapy. The low pharmacological adherence was reduced by 3.35%. Conclusions The implementation of a community-based care strategy in Santander at the first three visits achieved a relevant reduction of hypertension values and greater use of combined antihypertensive therapy. Continuation of the study is required to identify the total results.

What Women with HIV Know about Heart Health and Cardiovascular Risk and Intervention Preferences.

Cardiovascular disease (CVD) is a significant health concern influenced by various determinants. Stigma and resilience have emerged as factors in CVD development and management. Women with HIV (WWH) have higher CVD rates than women without HIV. To improve cardiovascular health for WWH, a comprehensive understanding of how these factors interact, the understanding about individual awareness and willingness to engage in risk-reduction interventions are needed. Methods: As part of a study examining CVD risk among WWH aged >35 years old, 90-min focus groups were conducted (May 2022) in the English language. Focus groups aimed to elicit participants' CVD risk knowledge and potential prevention strategies. Transcripts underwent a qualitative analysis. Results: Nineteen WWH participated in three focus groups. Participants experienced the following: (a) enacted stigma related to their HIV diagnosis (e.g., family, church member, healthcare staff); (b) a recent event (e.g., hospitalization of self/family, death in family, chest pain) triggered both heart health-promoting lifestyle changes and suboptimal health behaviors (e.g., COVID-19 pandemic: unhealthy snacking). Participants wanted to obtain more knowledge ("on a mission") about CVD risk. In total, 100% expressed willingness to take medication or embark on other lifestyle changes to prevent future CVD events. Although participants identified preventative heart health behaviors (e.g., eating healthy foods; exercising; limiting stress, substances, and smoking), misconceptions were also identified (e.g., "catching" heart disease). Conclusions: Understanding the interplay of the different factors related to heart health is needed both at the provider and the patient level to inform interventions that reduce CVD risk amongst racial/ethnic minoritized women with HIV, living in the Southern region of the US.

Association between Planetary Health Diet and Cardiovascular Disease: A Prospective Study from the UK Biobank.

The Planetary Health Diet index (PHDI) prioritizes the well-being of both individuals and the planet but has yielded mixed results on cardiovascular disease (CVD). Our aim was to assess the association between the PHDI and risk of CVD. A cohort of 118,469 individuals aged 40-69 years from the UK Biobank, who were free of CVD at 2009-2012 and followed-up to 2021. The PHDI was calculated using at least two 24-h dietary assessments and included 14 food groups, with a possible range from 0 to130 points. CVD incidence was defined as primary myocardial infarction or stroke and obtained from clinical records and death registries. During a 9.4-year follow-up, 5,257 incident cases of CVD were ascertained. When comparing the highest (89.9-128.5 points) versus the lowest quartile (21.1-71.1 points) of PHDI adherence, the multivariable-adjusted hazard ratio (95% confidence interval) was 0.86 (0.79, 0.94) for CVD, 0.88 (0.80, 0.97) for myocardial infarction, and 0.82 (0.70, 0.97) for stroke. The association was linear until a plateau effect was reached at 80 points of adherence to PHDI. Results remained robust when excluding participants with type 2 diabetes, including only those with three or more diet assessments, or excluding CVD cases in the first three years of follow-up. The food group components of the PHDI more strongly associated with reduced CVD risk were higher consumption of whole grains, whole fruits, fish and lower consumption of added sugars and fruit juices. In this large cohort of middle-aged and older British adults, adherence to the PHDI was associated with lower risk of CVD. These results provide empirical evidence that this dietary pattern, thought to be environmentally sustainable, benefits cardiovascular health.

Biological aging mediates the association between periodontitis and cardiovascular disease: results from a national population study and Mendelian randomization analysis

BackgroundThe relationship between periodontitis and cardiovascular disease (CVD) has been extensively studied, but the role of biological aging in this relationship remains poorly understood. This study is dedicated to investigating the effect of periodontitis on the incidence of CVD and to elucidating the potential mediating role of biological aging. Furthermore, this study will seek to elucidate the causal association between periodontitis, CVD, and biological aging.MethodsWe included 3269 participants from the National Health and Nutrition Examination Survey (2009–2014) with diagnostic information on periodontitis and composite CVD events. Biological aging was evaluated by utilizing both the Klemera–Doubal method’s calculated biological age (KDMAge) and phenotypic age (PhenoAge). Logistic regression, restricted cubic spline (RCS) analysis, and subgroup analysis were used for data analysis. Mediation analysis was employed to explore the mediating role of biological aging. Subsequently, Mendelian randomization (MR) analyses were performed using genome-wide association study databases to explore potential causal relationships between periodontitis, CVD, and biological aging.ResultsPeriodontitis was associated with a higher risk of CVD. Participants with periodontitis were found to have increased levels of biological aging, and elevated levels of biological aging were associated with increased CVD risk. Mediation analyses showed a partial mediating effect of biological aging (PhenoAge: 44.6%; KDMAge: 22.9%) between periodontitis and CVD risk. MR analysis showed that periodontitis played a causal role in increasing the risk of small vessel stroke, while myocardial infarction was found to increase the risk of periodontitis. In addition, reverse MR analysis showed that phenotypic aging can increase the risk of periodontitis, and there is a two-way causal relationship between CVD and biological aging.ConclusionsPeriodontitis is associated with an increased CVD risk, partially mediated by biological aging, with a complex causal interrelationship. Targeted interventions for periodontal health may slow the biological aging processes and reduce CVD risk.

Risk of Incident Cardiovascular Events Following Roux en Y Gastric Bypass versus Sleeve Gastrectomy: A Claims-Based Retrospective Cohort Study.

To compare the risk of incident cardiovascular disease (CVD) events following sleeve gastrectomy (SG) and Roux en Y gastric bypass (RYGB). Bariatric surgery is associated with reduced CVD risk but the differential effect of contemporary bariatric procedures is unclear. We used insurance claims to conduct a retrospective cohort study of CVD outcomes for patients who underwent RYGB versus SG between 2010 and 2021. Patients were followed for up to 5 years for a primary composite major adverse cardiovascular event (MACE) outcome as well as individual outcomes including myocardial infarction, stroke, heart failure, and arrhythmia. We compared cumulative risks of CVD events using multivariable Cox proportional hazards modeling, in overall cohorts and in sub-cohorts of older adults and those with type 2 diabetes (T2D) or pre-existing CVD and elevated morbidity. Matched, weighted cohorts of 13,545 SG and RYGB patients were observed for an average of 2.5 years after surgery, with 26.2% not lost to follow-up by the end of 5 years. There was no difference in MACE risk between procedures (aHR 1.01 for RYGB vs. SG [95% CI 0.90, 1.12]) in the overall cohort or among the subgroup of older adults (aHR 0.97 for RYGB vs. SG [95% CI 0.85, 1.10]). Patients with T2D experienced lower risk of MACE following RYGB compared to SG (aHR 0.78 [95% CI 0.66, 0.92]), as did those with pre-existing CVD or elevated morbidity prior to surgery (aHR 0.81 [95% CI 0.70, 0.93]). These findings further support the preferential use of RYGB over SG for patients with T2D or who have pre-existing CVD. However, among other groups of patients, including older adults, we did not observe a relative benefit of RYGB during the time horizon in this study.

Dose-Response Relationship Between Physical Activity and the Morbidity and Mortality of Cardiovascular Disease Among Individuals With Diabetes: Meta-Analysis of Prospective Cohort Studies.

Diabetes, a chronic condition affecting various organs, is frequently associated with abnormal lipid metabolism, notably increased cholesterol and triglyceride levels. These lipid abnormalities are closely linked to the development and advancement of cardiovascular disease (CVD). Although regular physical activity (PA) has consistently shown benefits in reducing CVD risk in the general population, its precise influence on CVD risk among patients with diabetes remains uncertain, particularly regarding dose-response relationships. This study aimed to summarize the evidence from prospective studies on the association between PA and CVD morbidity and mortality in individuals with diabetes and explore the optimal levels for public health recommendation. We systematically reviewed prospective cohort studies in PubMed, Embase, and Web of Science up to December 2022, with inclusion criteria specifying the studies published in English and included adult participants diagnosed with diabetes. A random effects model was used to pool the relative risk (RR) with the corresponding 95% CI comparing the highest with the lowest PA categories in each study for qualitative evaluation. In addition, linear and spline regression analyses were used to estimate dose-response associations. The meta-analysis included 12 prospective cohort studies, involving a total of 109,820 participants with diabetes. The combined results revealed that higher levels of PA were associated with a reduced risk of CVD. The RR of CVD for the highest compared with the lowest PA category was 0.62 (95% CI 0.51-0.73). In addition, there were 4 studies describing leisure-time PA, and the pooled RR was 0.68 (95% CI 0.52-0.83) for the highest versus the lowest activity. The linear regression model revealed that each 10 MET (metabolic equivalent of task)-hours per week of incrementally higher PA was associated with a 19% (95% CI 11.6-25.7) and a 6.9% (95% CI 4.5-9.3) reduction in CVD morbidity and mortality. Additionally, spline regression curves showed nonlinear relationships between PA levels and the risk of CVD and CVD mortality (both Pnonlinearity<.001), with a limited reduction in CVD risk and some further reduction in CVD mortality above 20 MET-hours per week of PA levels. For patients with diabetes, especially type 2 diabetes, there was a dose-response relationship between increased PA and reduced risk of CVD morbidity and mortality. The observed PA threshold is consistent with the recommended level for the general population. Gradually moving from inactivity to a guideline-recommended PA level could therefore significantly reduce the burden of CVD in patients with diabetes.

Anxiety and Depression Associated With Increased Cardiovascular Disease Risk Through Accelerated Development of Risk Factors

BackgroundPrior studies have incompletely assessed whether the development of cardiometabolic risk factors (CVDRF) (hypertension, hyperlipidemia, and diabetes mellitus) mediates the association between anxiety and depression (anxiety/depression) and cardiovascular disease (CVD). ObjectivesThe authors aimed to evaluate the following: 1) the association between anxiety/depression and incident CVDRFs and whether this association mediates the increased CVD risk; and 2) whether neuro-immune mechanisms and age and sex effects may be involved. MethodsUsing a retrospective cohort design, Mass General Brigham Biobank subjects were followed for 10 years. Presence and timing of anxiety/depression, CVDRFs, and CVD were determined using ICD codes. Stress-related neural activity, chronic inflammation, and autonomic function were measured by the assessment of amygdalar-to-cortical activity ratio, high-sensitivity CRP, and heart rate variability. Multivariable regression and mediation analyses were employed. ResultsAmong 71,214 subjects (median age 49.6 years; 55.3% female), 27,048 (38.0%) developed CVDRFs during follow-up. Pre-existing anxiety/depression associated with increased risk of incident CVDRF (OR: 1.71 [95% CI: 1.59-1.83], P < 0.001) and with a shorter time to their development (β = −0.486 [95% CI: −0.62 to −0.35], P < 0.001). The development of CVDRFs mediated the association between anxiety/depression and CVD events (log-odds: 0.044 [95% CI: 0.034-0.055], P < 0.05). Neuro-immune pathways contributed to the development of CVDRFs (P < 0.05 each) and significant age and sex effects were noted: younger women experienced the greatest acceleration in the development of CVDRFs after anxiety/depression. ConclusionsAnxiety/depression accelerate the development of CVDRFs. This association appears to be most notable among younger women and may be mediated by stress-related neuro-immune pathways. Evaluations of tailored preventive measures for individuals with anxiety/depression are needed to reduce CVD risk.

Effects of ACLY Inhibition on Body Weight Distribution: A Drug Target Mendelian Randomization Study.

Background: Adenosine triphosphate-citrate lyase (ACLY) inhibition has proven clinically efficacious for low-density lipoprotein cholesterol (LDL-c) lowering and cardiovascular disease (CVD) risk reduction. Clinical and genetic evidence suggests that some LDL-c lowering strategies, such as 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) inhibition with statin therapy increase body weight and the risk of developing type 2 diabetes mellitus (T2DM). However, whether ACLY inhibition affects metabolic risk factors is currently unknown. We aimed to investigate the effects of ACLY inhibition on glycaemic and anthropometric traits using Mendelian randomization (MR). Methods: As genetic instruments for ACLY inhibition, we selected weakly correlated single-nucleotide polymorphisms at the ACLY gene associated with lower ACLY gene expression in the eQTLGen study (N = 31,684) and lower LDL-c levels in the Global Lipid Genetic Consortium study (N = 1.65 million). Two-sample Mendelian randomization was employed to investigate the effects of ACLY inhibition on T2DM risk, and glycaemic and anthropometric traits using summary data from large consortia, with sample sizes ranging from 151,013 to 806,834 individuals. Findings for genetically predicted ACLY inhibition were compared to those obtained for genetically predicted HMGCR inhibition using the same instrument selection strategy and outcome data. Results: Primary MR analyses showed that genetically predicted ACLY inhibition was associated with lower waist-to-hip ratio (β per 1 standard deviation lower LDL-c: -1.17; 95% confidence interval (CI): -1.61 to -0.73; p < 0.001) but not with risk of T2DM (odds ratio (OR) per standard deviation lower LDL-c: 0.74, 95% CI = 0.25 to 2.19, p = 0.59). In contrast, genetically predicted HMGCR inhibition was associated with higher waist-to-hip ratio (β = 0.15; 95%CI = 0.04 to 0.26; p = 0.008) and T2DM risk (OR = 1.73, 95% CI = 1.27 to 2.36, p < 0.001). The MR analyses considering secondary outcomes showed that genetically predicted ACLY inhibition was associated with a lower waist-to-hip ratio adjusted for body mass index (BMI) (β = -1.41; 95%CI = -1.81 to -1.02; p < 0.001). In contrast, genetically predicted HMGCR inhibition was associated with higher HbA1c (β = 0.19; 95%CI = 0.23 to 0.49; p < 0.001) and BMI (β = 0.36; 95%CI = 0.23 to 0.49; p < 0.001). Conclusions: Human genetic evidence supports the metabolically favourable effects of ACLY inhibition on body weight distribution, in contrast to HMGCR inhibition. These findings should be used to guide and prioritize ongoing clinical development efforts.

Reducing cardiovascular risk - are omega 3 fatty acids the solution?

Introduction and objective Omega-3 fatty acids possess numerous physiological characteristics, including anti-inflammatory, lipid-lowering, antiarrhythmic, and antithrombotic effects. There has been an ongoing discussion about their potential positive effects on human health and the extent of their influence. In this review, we will explore the current understanding of how omega-3 fatty acids impact the development of cardiovascular diseases. Review methods A review of publications on the effects of omega 3 fatty acids was conducted using the PubMed platform. The main keywords used in the search were "omega 3 fatty acids" and "cardiovascular diseases". The search included a review of the latest scientific work on the effects of omega 3 fatty acids on the body. Abbreviated description of the state of knowledge Omega-3 fatty acids exhibit diverse molecular mechanisms that are beneficial in combating cardiovascular diseases. Reducing serum triglycerides is one of the ways in which omega 3 fatty acids have an advantageous effect on the cardiovascular system. Dietary sources and supplementation offer potential benefits. Summary Omega-3 fatty acids, including EPA and DHA, exhibit various molecular mechanisms such as antithrombotic, anti-inflammatory, and lipid-lowering effects, which are crucial in combating CVDs. Dietary sources of omega-3 include both animal and plant products. Supplementing with omega-3 fatty acids, particularly in patients with elevated triglyceride levels, can significantly reduce CVD risk factors and mortality rates. Recommendations suggest consuming 2 servings of fish per week or supplementing with DHA + EPA to support cardiovascular health. Despite some controversies in research findings, omega-3 supplementation remains beneficial. Ongoing research continues to explore the optimal use and efficacy of omega-3 fatty acids in cardiovascular health.

Reduced Risk of Cardiovascular Diseases after Bariatric Surgery Based on the New PREVENT Equations.

We applied the novel Predicting Risk of Cardiovascular Disease EVENTs (PREVENT) equations to evaluate cardiovascular-kidney-metabolic (CKM) health and estimated CVD risk, including heart failure (HF), after bariatric surgery. Among 7804 patients (20-79 years) undergoing bariatric surgery at Vanderbilt University Medical Center during 1999-2022, CVD risk factors at pre-surgery, 1-year, and 2-year post-surgery were extracted from electronic health records. The 10- and 30-year risks of total CVD, atherosclerotic CVD (ASCVD), coronary heart disease (CHD), stroke, and HF were estimated for patients without a history of CVD or its subtypes at each time point, using the social deprivation index-enhanced PREVENT equations. Paired t-tests or McNemar tests were used to compare pre- with post-surgery CKM health and CVD risk. Two-sample t-tests were used to compare CVD risk reduction between patient subgroups defined by age, sex, race, operation type, weight loss, and history of diabetes, hypertension, and dyslipidemia. CKM health was significantly improved after surgery with lower systolic blood pressure, non-high-density-lipoprotein cholesterol (non-HDL), and diabetes prevalence, but higher HDL and estimated glomerular filtration rate (eGFR). The 10-year total CVD risk decreased from 6.51% at pre-surgery to 4.81% and 5.08% at 1- and 2-year post-surgery (relative reduction: 25.9% and 16.8%), respectively. Significant risk reductions were seen for all CVD subtypes (i.e., ASCVD, CHD, stroke, and HF), with the largest reduction for HF (relative reduction: 55.7% and 44.8% at 1- and 2-year post-surgery, respectively). Younger age, White race, >30% weight loss, diabetes history, and no dyslipidemia history were associated with greater HF risk reductions. Similar results were found for the 30-year risk estimates. Bariatric surgery significantly improves CKM health and reduces estimated CVD risk, particularly HF, by 45-56% within 1-2 years post-surgery. HF risk reduction may vary by patient's demographics, weight loss, and disease history, which warrants further research.
