The potential of flavonoids to mitigate cellular senescence in cardiovascular disease

Aging is one of the most significant factors affecting cardiovascular health, with cellular senescence being a central hallmark. Senescent cells (SCs) secrete a specific set of signaling molecules known as the senescence-associated secretory phenotype (SASP). The SASP has a remarkable impact on age-associated diseases, particularly cardiovascular diseases (CVD). Targeting SCs through anti-aging therapies represents a novel strategy to effectively retard senescence and attenuate disease progression. Accumulating evidence demonstrates that the flavonoids, widely presented in fruits and vegetables worldwide, can delay or treat CVD via selectively eliminating SCs (senolytics) and modulating SASPs (senomorphics). Nevertheless, only sporadic research has illustrated the application of flavonoids in targeting SCs for CVD, which requires further exploration. This review recapitulates the hallmarks and key molecular mechanisms involved in cellular senescence, then summarizes senescence of different types of cardiac cells and describes the mechanisms by which cellular senescence affects CVD development. The discussion culminates with the potential use of flavonoids via exerting their biological effects on cellular senescence to reduce CVD incidence. This summary will provide valuable insights for cardiovascular drug design, development and clinical applications leveraging flavonoids.

Exploring the Link Between Genetic Predictors of Cardiovascular Disease and Psoriasis

Importance

The epidemiological link between immune-mediated diseases (IMIDs) and cardiovascular disease has often been attributed to systemic inflammation. However, the direction of causality and the biological mechanisms linking cardiovascular disease with IMIDs are incompletely understood. Given the robust epidemiological association and the growing body of supportive mechanistic evidence, psoriasis is an exemplary IMID model for exploring this relationship.

Objective

To assess the bidirectional relationships between genetic predictors of psoriasis and the 2 major forms of cardiovascular disease, coronary artery disease (CAD) and stroke, and to evaluate the association between genetic predictors of cardiovascular disease with 9 other IMIDs.

Design, Setting, and Participants

This was a genetic association study using mendelian randomization (MR), a powerful genetic tool to help distinguish causation from associations observed in epidemiological studies, to provide supportive evidence for causality between traits. The study conducted 2-sample MR analyses using summary-level data from large-scale genome-wide association meta-analysis studies (GWAS) for each trait. The analysis focused on individuals of European descent from GWAS meta-analyses, involving CAD, stroke, psoriasis, and 9 other IMIDs. Data were analyzed from January 2023 to May 2024.

Exposures

Genetic predictors of CAD, stroke, psoriasis, and 9 other IMIDs.

Main Outcomes and Measures

The primary outcomes were the associations of genetic predictors of CAD and stroke with the risk of psoriasis and 9 other IMIDs, determined using inverse-variance weighted (IVW) MR estimates.

Results

This study included 181 249 cases and 1 165 690 controls with CAD, 110 182 cases and 1 503 898 controls with stroke, 36 466 cases and 458 078 controls with psoriasis, for a total of approximately 3 400 000 individuals, and 9 other IMIDs. In contrast to previous assumptions, genetic predictors of psoriasis were found to have no association with CAD or stroke. In the reverse direction, genetic predictors of both CAD (MR estimate IVW odds ratio [OR], 1.07; 95% CI, 1.04-1.10; P = .003) and stroke (IVW OR, 1.22; 95% CI, 1.05-1.41; P = .01) were found to have risk-increasing associations with psoriasis. Adjusting for stroke rendered the associations of genetically predicted CAD with psoriasis risk nonsignificant (and vice versa), suggesting that a shared effect underlying genetic risk for CAD and stroke associates with increased psoriasis risk. No risk-increasing associations were observed for genetic predictors of cardiovascular disease with other common IMIDs, including rheumatoid arthritis and inflammatory bowel disease.

Conclusions and Relevance

Findings of this mendelian randomization study indicate that genetic predictors of cardiovascular disease were associated with increased psoriasis risk with no reciprocal effect or association with other IMIDs. Elucidating mechanisms underpinning this association could lead to novel therapeutic approaches in both diseases.

Healthcare self-management support of stroke patients after discharge: A conceptual analysis using Rodger's evolutionary approach

AIM(S)

To explore the meaning of healthcare self-management support for post-discharged stroke patients.

METHOD

Rodgers' evolutionary approach was used to identify antecedents, attributes, related terms, surrogate terms and consequences.

DATA SOURCE

Literature from 2012 to 2022 was searched from MEDLINE, CINAHL, PsycINFO and Google Scholar.

RESULTS

Three antecedents preceded healthcare self-management support for post-discharged stroke patients: loss of inpatient support, preparedness for self-management and presence of self-management support. Healthcare self-management support for post-discharged stroke patients was defined by eight attributes: pre-discharge assessment and planning; provision of continuous education and training; collaborative goal-setting; reinforcement and documentation of vital information; coordination of post-discharge care; provision of rehabilitation support and promoting community reintegration; provision of counselling support; and using clear communication, patient empowerment and promoting self-efficacy. The identified consequences of the concept were as follows: improved patient outcomes; improved life quality; decreased healthcare cost; decreased re-admission rate and inpatient care burden; and decreased complication rate.

CONCLUSION

Healthcare self-management support for post-discharged stroke patients is an emerging concept that can help to significantly improve stroke patients' health outcomes and life quality. However, its applicability is uncertain considering the workload, time and resources available to healthcare professionals. There is a need for future studies to focus on the feasibility and applicability of this concept in clinical practice and to identify any challenges healthcare providers may have in supporting stroke patients after discharge.

IMPACT

This concept analysis brings clarity to the concept of healthcare self-management support of post-discharged stroke patients and distinguishes it from other self-management supports. It provides an opportunity for further studies and a pathway for generalized healthcare self-management support for stroke patients after discharge to improve health outcomes and quality of life.

NO PATIENT OR PUBLIC CONTRIBUTION

No patients, service users, caregivers or members of the public were involved in conducting this concept analysis.

Associations between the Serum Triglyceride Level and Kidney Outcome in Patients with Chronic Kidney Disease: The Fukuoka Kidney disease Registry Study

AIMS

Hypertriglyceridemia is a risk factor for chronic kidney disease (CKD). However, whether or not it predicts the risk of CKD progression is unknown. This study evaluated the association between serum triglyceride (TG) levels and kidney disease progression in patients with non-dialysis-dependent CKD.

METHODS

The Fukuoka Kidney disease Registry (FKR) study was a multicenter, prospective longitudinal cohort study. In total, 4,100 patients with CKD were followed up for 5 years. The primary outcome was the incidence of CKD progression, defined as a ≥ 1.5-fold increase in serum creatinine level or the development of end-stage kidney disease. The patients were divided into quartiles according to baseline serum TG levels under non-fasting conditions: Q1 ＜87 mg/dL; Q2, 87-120 mg/dL; Q3, 121-170 mg/dL, and Q4 ＞170 mg/dL.

RESULTS

During the 5-year observation period, 1,410 patients met the criteria for CKD progression. The multivariable-adjusted Cox proportional hazards model showed a significant association between high serum TG level and the risk of CKD progression in the model without macroalbuminuria as a covariate (multivariable hazard ratio[HR] for Q4 versus Q1, 1.20; 95% CI, 1.03-1.41; P=0.022), but the significance disappeared after adjusting for macroalbuminuria (HR for Q4 versus Q1, 1.06; 95% CI, 0.90-1.24; P=0.507).

CONCLUSIONS

The present findings suggest that individuals with high serum TG levels are more likely to develop CKD progression than those without; however, whether or not higher serum TG levels reflect elevated macroalbuminuria or lead to CKD progression via elevated macroalbuminuria is unclear.

Incidental Coronary Artery Calcification and the Risk of Major Adverse Cardiovascular Outcomes

Background Incidental findings of coronary artery calcifications (CACs) are not consistently reported, and the clinical significance relating to cardiovascular outcomes remains to be established. In this single-center cross-sectional study, we assessed the association between incidental coronary artery calcification documented on formal chest CT reports and the incidence of major adverse cardiovascular events (MACE). Methods A MACE was defined as the occurrence of stroke or transient ischemic attack or ST-segment elevation myocardial infarction, non-ST-elevation myocardial infarction, or undergoing coronary artery bypass grafting. A composite endpoint included either MACE or the occurrence of cardiovascular death. We assessed the predictors of the composite outcome and the effect of lipid-lowering therapy on the composite outcome in the studied cohort.  Results The composite outcome occurred in 39.1% of the 1,354 subjects studied. Peripheral arterial disease was the only comorbid condition associated with increased odds (adjusted odds ratio (aOR) 2.6, p < 0.001, 95% CI: 1.9 - 3.56). The average treatment effect of lipid-lowering therapy was 0.11 (p = 0.002, 95% CI: 0.04 - 0.17). At 10 years after the first CAC report, the presence of peripheral artery disease appears to present the lowest odds of survival, which is <50% (hazard ratio (HR) 2.44, p < 0.001, 95% CI: 1.67 - 3.56). Conclusion In patients with CAC on incidental chest CT scans, the presence of peripheral arterial disease is associated with increased odds of MACE and/or cardiovascular death. In those with incidental CAC on non-gated chest CT scans, the residual risk for MACE remains high despite lipid-lowering therapy and antiplatelet agents.

A Prospective Study on Lifestyle Factors, Body Mass Index Changes, and Lipitension Risk in Japanese Young and Middle-Aged Women

Background: This study investigates how lifestyle factors and westernization contribute to obesity and examines the influence of body mass index (BMI) changes and lifestyle factors on "lipitension," a significant risk factor for heart disease and metabolic syndrome. Methods: This prospective study focused on women aged 20-64 without pre-existing hypertension and dyslipidemia who underwent regular medical checkups between April 2016 and March 2022. Anthropometric measurements and blood pressure, along with low-density lipoprotein, high-density lipoprotein, and triglycerides levels, were assessed. Results: Over an average 46.5-month follow-up, 11.5% of initially healthy young and middle-aged women developed lipitension. Categorizing participants based on BMI changes revealed stable (63.8%), decreased (12.5%), and increased (23.8%) groups within this 11.5%. Increased BMI is linked with a heightened hazard risk for lipitension. Women with increased BMI who refrained from snacking (aHR [95% confidence interval (CI)] = 2.750 [1.433-5.279]), avoided late-night eating (aHR [95% CI] = 1.346 [1.032-1.754]), and engaged in alcohol consumption (aHR [95% CI] = 2.037 [1.138-3.646]) showed an elevated risk. Conversely, within the decreased BMI group, behaviors like skipping breakfast (aHR [95% CI] = 0.190 [0.047-0.764]), eating quickly (aHR [95% CI] = 0.457 [0.215-0.972]), and not eating late (aHR [95% CI] = 0.665 [0.467-0.948]) were associated to a reduced lipitension. Subgroup analysis for women with BMI <23 revealed specific behaviors influencing lipitension risk in both BMI-increased and BMI-stable groups. Conclusion: Customized interventions, including for women with BMI <23, enhance heart health, mitigating global lifestyle diseases and obesity.

2024 Guidelines of the Taiwan Society of Cardiology on the Primary Prevention of Atherosclerotic Cardiovascular Disease --- Part II

For the primary prevention of atherosclerotic cardiovascular disease (ASCVD), the recommended treatment target for each modifiable risk factor is as follows: reducing body weight by 5-10%; blood pressure < 130/80 mmHg (systolic pressure < 120 mmHg in high-risk individuals); low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL in high-risk individuals, LDL-C < 115 mg/dL in moderate-risk individuals, LDL-C < 130 mg/dL in low-risk individuals, and LDL-C < 160 mg/dL in those with a minimal; complete and persistent abstinence from cigarette smoking; hemoglobin A1C < 7.0%; fulfilling recommended amounts of the six food groups according to the Taiwan food guide; and moderate-intensity physical activity 150 min/wk or vigorous physical activity 75 min/wk. For the primary prevention of ASCVD by pharmacological treatment in individuals with modifiable risk factors/clinical conditions, statins are the first-line therapy for reducing LDL-C levels; some specific anti-diabetic drugs proven to be effective in randomized controlled trials for the primary prevention of ASCVD are recommended in patients with type 2 diabetes mellitus; pharmacological treatment is recommended to assist in weight management for obese patients with a body mass index ≥ 30 kg/m2 (or 27 kg/m2 who also have at least one ASCVD risk factor or obesity-related comorbidity); an angiotensin-converting enzyme inhibitor, a glucagon-like peptide-1 receptor agonist, a sodium-dependent glucose cotransporter-2 inhibitor, and finerenone can be used in diabetic patients with chronic kidney disease for the primary prevention of ASCVD. Of note, healthcare providers are at full discretion in clinical practice, owing to the diversity of individuals and practice, and the availability of resources and facilities.

Influence of sleep on physiological systems in atherosclerosis

Sleep is a fundamental requirement of life and is integral to health. Deviation from optimal sleep associates with numerous diseases including those of the cardiovascular system. Studies, spanning animal models to humans, show that insufficient, disrupted or inconsistent sleep contribute to poor cardiovascular health by disrupting body systems. Fundamental experiments have begun to uncover the molecular and cellular links between sleep and heart health while large-scale human studies have associated sleep with cardiovascular outcomes in diverse populations. Here, we review preclinical and clinical findings that demonstrate how sleep influences the autonomic nervous, metabolic and immune systems to affect atherosclerotic cardiovascular disease.

Analysis of Depression in Aged, Hospitalized Patients with Chronic Heart Failure

Objective

The objective is to investigate the situation and risk factors of depression in aged, hospitalized patients with chronic heart failure (CHF).

Methods

A total of 196 aged CHF patients admitted to Xuanwu Hospital from May 2022 to March 2024 were consecutively selected. Information such as demographics, comorbidities, old-age hospitalization assessment results, and admission test results was collected. Differences were found between the patients admitted with CHF and depression and those without depression. Independent predictors of depression in aged, hospitalized patients with CHF were identified using logistic regression analyses. The sensitivity and specificity of age, frailty score, and New York Heart Association (NYHA) classification to evaluate the occurrence of depression were examined by calculating the area under the curve (AUC) of the receiver operating characteristic (ROC) curve.

Results

Increased age [OR (Odds Ratio) = 1.132, (95% CI [Confidence Interval], 1.050-1.221), P = .001], higher frailty score [OR = 8.324, (95% CI, 4.233-16.368), P < .001], and higher NYHA classification [OR = 3.806, (95% CI, 1.864-7.773), P < .001] were independent predictors of depression in aged CHF hospitalized patients. The best indicators for the occurrence of depressive symptoms were age of 75 years, a score of 2 for frailty, and an NYHA classification of III. The AUCs for age, frailty score, and NYHA classification were 0.764, 0.876, and 0.707, respectively.

Conclusion

Clinical assessment of depression is necessary for aged, hospitalized CHF patients. Patients over 75 years old, with a frailty score of at least 2, and an NYHA classification of III or IV are more prone to depression, which requires attention.

Tipping the scale: Effects of physical activity and body composition on cardiac parameters in postmenopausal females

The risk of cardiovascular disease increases significantly after menopause. We sought to assess the impact of different activity levels on cardiac structure and function in postmenopausal women. We grouped age-similar, postmenopausal women by self-reported physical activity levels over two decades. The study involved 34 women (age 61 ± 1 years; 11 ± 2 postmenopausal years; body mass index 23 ± 3 kg/m2) categorized into three activity tiers: sedentary (SED; ≤1 h exercise weekly; n = 9); moderately active (MOD; ≥2 ≤6 h low/moderate intensity exercise weekly; n = 11) and highly active (HIGH; >4 h of moderate/high intensity exercise weekly; n = 14). Maximum oxygen uptake (VO2max) differed significantly (p < 0.05) between the groups (24.9 ± 5.8; 30.5 ± 5.8; 38.4 ± 4.4 mL O2/kg/min; SED, MOD and HIGH respectively). Conversely, there were no differences (p > 0.05) in height, Total fat-free mass, body surface area or in echocardiographic measures of left ventricular (LV) morphology, systolic function, diastolic function and right ventricular function. Contrary to our hypothesis, these findings reveal that marked differences in activity level and VO2max are not reflected in measures of LV morphology or echocardiographic indicators of cardiac diastolic or systolic function in postmenopausal women of similar body size.

Analysis of the effectiveness of multi-disciplinary team integrated management combined with full-media health education intervention in patients with coronary heart disease and diabetes mellitus

OBJECTIVE

To study the effect of a multi-disciplinary team (MDT) integrated management combined with all-media health education intervention on patients with coronary heart disease (CHD) and diabetes mellitus (DM).

METHODS

Fasting plasma glucose (FPG), systolic blood pressure (SBP), and total cholesterol (TC) were evaluated before and after the intervention. The general self-efficacy scale (GSES) was utilized to assess the self-efficacy. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate depression and anxiety. The Seattle Angina Questionnaire (SAQ), a CHD-specific functional status and quality of life self-measurement tool, was employed to evaluate the quality of life.

RESULTS

After the intervention, the levels of FPG, systolic blood pressure, SAS, SDS, and TC in the three groups all decreased (C>B>A,P<0.05). After the intervention, the self-efficacy scores of all three groups were improved (A>B>C, P < 0.05). After the intervention, the score of quality of life in group A and group B was higher than that in group C, and the score in group A was higher than that in group B (P<0.05).

CONCLUSION

MDT integrated management combined with all-media health education intervention can effectively ameliorate blood glucose, blood pressure, and blood lipids of patients with CHD and DM, promote their healthy life, improve their self-efficacy, and improve their negative emotions and quality of life.

Noncoding RNAs regulating ferroptosis in cardiovascular diseases: novel roles and therapeutic strategies

The morbidity and mortality rates of cardiovascular diseases (CVDs) are increasing; thus, they impose substantial health and economic burdens worldwide, and effective interventions are needed for immediate resolution of this issue. Recent studies have suggested that noncoding RNAs (ncRNAs) play critical roles in the occurrence and development of CVDs and are potential therapeutic targets and novel biomarkers for these diseases. Newly discovered modes of cell death, including necroptosis, pyroptosis, apoptosis, autophagy-dependent cell death and ferroptosis, also play key roles in CVD progression. However, ferroptosis, which differs from the other aforementioned forms of regulated cell death in terms of cell morphology, biochemistry and inhereditability, is a unique iron-dependent mode of nonapoptotic cell death induced by abnormal iron metabolism and excessive accumulation of iron-dependent lipid peroxides and reactive oxygen species (ROS). Increasing evidence has confirmed that ncRNA-mediated ferroptosis is involved in regulating tissue homeostasis and CVD-related pathophysiological conditions, such as cardiac ischemia/reperfusion (I/R) injury, myocardial infarction (MI), atrial fibrillation (AF), cardiomyopathy and heart failure (HF). In this review, we summarize the underlying mechanism of ferroptosis, discuss the pathophysiological effects of ncRNA-mediated ferroptosis in CVDs and provide ideas for effective therapeutic strategies.

The Role of Cardiac Computed Tomography Angiography in Risk Stratification for Coronary Artery Disease

Coronary computed tomography angiography (CCTA) allows the assessment of the presence and severity of obstructive and nonobstructive atherosclerotic coronary artery disease. With software developments incorporating artificial intelligence-based automated image analysis along with improved spatial resolution of CT scanners, volumetric measurements of atherosclerotic plaque, detection of high-risk plaque features, and delineation of pericoronary adipose tissue density can now be readily and accurately evaluated for a given at-risk patient. Many of these expanded diagnostic measures have been shown to be prognostically useful for prediction of major adverse cardiac events. The incremental value of plaque quantification over diameter stenosis has yet to be thoroughly discovered in current studies. Furthermore, the physiological significance of lesions can also be assessed with CT-derived fractional flow reserve, myocardial CT perfusion, and more recently shear stress, potentially leading to selective invasive coronary angiography and revascularization. Along with these technological advancements, there has been additional high-quality evidence for CCTA including large randomized clinical trials supporting high-level recommendations from many international clinical practice guidelines. Current trials largely compare a CCTA vs functional testing strategy, yet there is minimal evidence on CCTA plaque-guided therapeutic trials to measure regression of atherosclerosis and prevention of major coronary artery disease events. In this review, we summarize current evidence on comprehensive risk assessment with CCTA and future directions.

Tailoring Risk Prediction Models to Local Populations

Importance

Risk estimation is an integral part of cardiovascular care. Local recalibration of guideline-recommended models could address the limitations of existing tools.

Objective

To provide a machine learning (ML) approach to augment the performance of the American Heart Association's Predicting Risk of Cardiovascular Disease Events (AHA-PREVENT) equations when applied to a local population while preserving clinical interpretability.

Design, Setting, and Participants

This cohort study used a New England-based electronic health record cohort of patients without prior atherosclerotic cardiovascular disease (ASCVD) who had the data necessary to calculate the AHA-PREVENT 10-year risk of developing ASCVD in the event period (2007-2016). Patients with prior ASCVD events, death prior to 2007, or age 79 years or older in 2007 were subsequently excluded. The final study population of 95 326 patients was split into 3 nonoverlapping subsets for training, testing, and validation. The AHA-PREVENT model was adapted to this local population using the open-source ML model (MLM) Extreme Gradient Boosting model (XGBoost) with minimal predictor variables, including age, sex, and AHA-PREVENT. The MLM was monotonically constrained to preserve known associations between risk factors and ASCVD risk. Along with sex, race and ethnicity data from the electronic health record were collected to validate the performance of ASCVD risk prediction in subgroups. Data were analyzed from August 2021 to February 2024.

Main Outcomes and Measures

Consistent with the AHA-PREVENT model, ASCVD events were defined as the first occurrence of either nonfatal myocardial infarction, coronary artery disease, ischemic stroke, or cardiovascular death. Cardiovascular death was coded via government registries. Discrimination, calibration, and risk reclassification were assessed using the Harrell C index, a modified Hosmer-Lemeshow goodness-of-fit test and calibration curves, and reclassification tables, respectively.

Results

In the test set of 38 137 patients (mean [SD] age, 64.8 [6.9] years, 22 708 [59.5]% women and 15 429 [40.5%] men; 935 [2.5%] Asian, 2153 [5.6%] Black, 1414 [3.7%] Hispanic, 31 400 [82.3%] White, and 2235 [5.9%] other, including American Indian, multiple races, unspecified, and unrecorded, consolidated owing to small numbers), MLM-PREVENT had improved calibration (modified Hosmer-Lemeshow P > .05) compared to the AHA-PREVENT model across risk categories in the overall cohort (χ23 = 2.2; P = .53 vs χ23 > 16.3; P < .001) and sex subgroups (men: χ23 = 2.1; P = .55 vs χ23 > 16.3; P < .001; women: χ23 = 6.5; P = .09 vs. χ23 > 16.3; P < .001), while also surpassing a traditional recalibration approach. MLM-PREVENT maintained or improved AHA-PREVENT's calibration in Asian, Black, and White individuals. Both MLM-PREVENT and AHA-PREVENT performed equally well in discriminating risk (approximate ΔC index, ±0.01). Using a clinically significant 7.5% risk threshold, MLM-PREVENT reclassified a total of 11.5% of patients. We visualize the recalibration through MLM-PREVENT ASCVD risk charts that highlight preserved risk associations of the original AHA-PREVENT model.

Conclusions and Relevance

The interpretable ML approach presented in this article enhanced the accuracy of the AHA-PREVENT model when applied to a local population while still preserving the risk associations found by the original model. This method has the potential to recalibrate other established risk tools and is implementable in electronic health record systems for improved cardiovascular risk assessment.

Impact of Alcohol Consumption on Cardiovascular Events in Patients Undergoing Percutaneous Coronary Intervention

Background/Objectives: The impact of alcohol consumption and its restriction on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) remains elusive. We aimed to investigate the clinical outcomes in drinkers undergoing PCI. Methods: We included 77,409 patients who underwent PCI and a health check-up within one year of the PCI using a nationwide prospective database from the Korean National Health Insurance System. Primary outcomes were major adverse cardiovascular and cerebrovascular events (MACCE), a composite of all-cause mortality, myocardial infarction, coronary revascularization, and stroke. Patients were classified as non-drinkers, within-the-guideline (≤1 standard drink in women and ≤2 in men), and above-the-guideline drinkers based on drinking status at the first health check-up after PCI. Results: During a 4.0-year follow-up duration, MACCE incidence was 19.7% (n = 15,214) (4689 [6.1%] deaths, 1916 [2.5%] MI, 2033 [2.6%] strokes, and 10,086 [13.0%] revascularizations). Both within-the-guideline- (aHR [95%CI], 0.843 [0.773-0.919]) and above-the-guideline drinkers (0.829 [0.784-0.876]) had a lower MACCE risk than the non-drinkers. A characteristic J-curve relationship was observed between the frequency or body weight-adjusted alcohol consumption and MACCE risk, with the lowest risk in the once-per-week and a mild amount per body weight (≤0.33 g/kg/week) group. Drinking habits after PCI were associated with a lower risk of adverse cardiovascular outcomes; those who continued to drink before and after PCI had the lowest risk. Conclusions: Alcohol consumption was associated with a lower risk of adverse outcomes in patients undergoing PCI. Further studies with longer-term follow-up are warranted.

The Paradox of Physical Activity and Coronary Artery Calcification: Implications for Cardiovascular Risk

The introduction of CT scans and the subsequent Agatston score in the 1990s drastically improved our ability to detect coronary artery calcification (CAC). This led to its incorporation into cardiovascular risk assessment guidelines set forth by organizations such as the American Heart Association (AHA) and the American College of Cardiology (ACC). Over time, these guidelines have evolved significantly, reflecting an increasing understanding of CAC. Physical activity has become a key factor in the management of cardiovascular disease. However, the relationship between physical activity and CAC remains complex. Although physical activity is generally beneficial for cardiovascular health, paradoxically, high levels of physical activity have been associated with elevated CAC scores. However, these higher CAC levels may indicate the presence of more stable, calcified plaques that provide protection against plaque rupture. These contradictory findings call for balanced interpretations that acknowledge the cardiovascular benefits of physical activity. This review examines the historical development of clinical guidelines for CAC, the paradoxical relationship between physical activity and CAC, and potential underlying mechanisms. It emphasizes the need for future research to utilize objective measures and consistent methodologies to better understand the relationship between physical activity and CAC.

Interaction of CETP rs708272 Polymorphism on Trans Fatty Acid Intake and Glucose Metabolism Markers

Dietary fats influence gene expression and several metabolic pathways. Therefore, it is crucial to study the role of personal genotypes in the interaction between fat consumption and cardiometabolic markers. This research aimed to determine the interaction of the rs708272 polymorphism of CETP and the fatty acid intake with changes in the HOMA-IR in adults living with overweight or obesity. The current study was a secondary analysis of an 8-week controlled clinical trial. The final sample for this analysis comprised 78 Mexican adults with the Cholesteryl Ester Transfer Protein (CETP) rs708272 polymorphism who followed a dietary intervention. Using an interaction analysis, we evaluated the fatty acid intake and the genotypes of rs708272, with changes in blood glucose, insulin, and the HOMA-IR from baseline to endpoint. Our findings suggest a significant interaction between the trans fatty acid intake and the GG genotype with changes in glucose (p = 0.024), insulin (p = 0.004), and the HOMA-IR (p = 0.002). The higher the consumption of trans fatty acids, the less these markers of glucose metabolism were reduced. carriers of the GG genotype may benefit from limiting dietary trans fatty acid intake, as there was no reduction in plasma glucose and insulin despite a hypocaloric dietary intervention in adults with overweight and obesity.

Functional and prognostic impacts of serum albumin with thoracic arterial calcification among asymptomatic individuals

Although several studies have demonstrated the cardiovascular (CV) implication of hypoalbuminemia and arterial calcification among hemodialysis patients, little is known regarding their cardiac correlates and relevant CV outcomes in asymptomatic individuals. We assessed the potential CV interrelation between serum albumin (SA) and aortic calcification. Among 2,723 asymptomatic individuals underwent cardiovascular health check-up, we assessed serum albumin (SA) level, thoracic aortic calcification (TAC) and coronary artery calcification (CAC) by multi-detector computed tomography, and ultrasound-determined carotid plaque burden. We related these measures to cardiac structure/function and CV outcomes. Lower SA level was associated with higher TAC score and volume rather than carotid plaque or coronary calcification burden in fully adjusted models. By categorizing the study population into 4 groups by SA (>, ≤ 4.6 mg/dL) and presence of TAC, subjects classified into low SA/TAC(+) category were oldest with highest prevalent CV disease. Both lower SA and TAC(+) were independently associated with impaired myocardial systolic/diastolic mechanics and higher CV events during a median of 6.6 years (IQR: 5.1, 6.8 years) follow-up. Participants classified into low SA/TAC(+) category showed highest risk for CV events (adjusted HR: 3.78 [95% CI: 2.11, 6.77], high SA/TAC[-] as reference) in fully adjusted Cox model. Among symptom-free individuals, TAC was closely associated with low SA concentration in relation to unfavorable cardiac mechanics and may serve as a useful prognosticator for adverse CV events.

Application of Peplau's interpersonal relationship theory combined with case management in rehabilitation of patients after primary percutaneous coronary intervention

Objective

To explore the effect of Peplau's interpersonal relationship theory (PIRT) combined with case management (CM) on exercise-based cardiac rehabilitation (EBCR), self-efficacy of rehabilitation and risk factors in patients after primary percutaneous coronary intervention (PCI).

Methods

The convenience sampling method was used to select patients who were admitted to the Department of Cardiology in our hospital from January to October 2022 and received PCI for the first time. Patients were divided into a control group and an intervention group. The control group was given routine treatment and health guidance, including radial artery puncture site care, monitoring of vital signs, informing about medication and dietary precautions, etc. and the intervention group was given PIRT combined with CM. The study was conducted for 3 months. The effect of intervention in the two groups was evaluated by the coronary heart disease risk factor index, EBCR knowledge-attitude-behavior questionnaire and EBCR self-efficacy scale.

Results

The rate of risk factors control including blood pressure (p < 0.001), low density lipoprotein cholesterol (p = 0.012), smoking cessation (p = 0.031) and exercises (p = 0.021), the scores of EBCR knowledge (p < 0.001), attitude (p = 0.001) and behavior (p < 0.001), and the score of EBCR self-efficacy scale (p < 0.001) in the intervention group were better than those in the control group at 3 months after intervention.

Conclusion

Peplau's interpersonal relationship theory combined with appropriate case management can effectively control cardiovascular disease in patients after primary PCI.

Prediction of physical activity and nutritional behaviors based on social cognitive theory in middle-aged population at risk of coronary artery disease in Bandar Abbas

Coronary artery disease (CAD) is the most common cardiovascular disease and the main cause of mortality in developing countries. Since physical activity and nutritional behaviors are modifiable risk factors in people at risk of CAD, the present study aims to explore the effect of an intervention based on the social cognitive theory (SCT) on physical activity and nutritional behaviors in middle-aged population at risk of CAD in the city of Bandar Abbas. The present cross-sectional study was conducted on 519 middle-aged subjects who visited the healthcare centers in Bandar Abbas, southern Iran, in 2023. The sampling was simple randomization. The data were collected using the general physical activity questionnaire, nutritional behavior questionnaire and a questionnaire based on the social cognitive theory (SCT). Descriptive statistics were used to describe the demographic features of the sample. Pearson correlation coefficient was used to test the relationship between the variables of study. Multiple linear regression was used to test the effect of the SCT constructs on physical activity and nutrition behaviors. All statistical analyses and hypothesis testing were done in SPSS 21, at a significance level of 0.05. A total number of 519 subjects participated in this study, whose average age was 44.23 ± 7.14 years. The results of Pearson correlation test showed a statistically significant positive correlation between nutritional behaviors and the constructs of self-efficacy, collective efficacy, outcome expectations, observational learning, normative beliefs, barriers and opportunities, reinforcement and punishment, and behavioral intention. There was also a significant positive correlation between physical activity and self-efficacy, normative beliefs, social support and behavioral intention. Social support, self-efficacy, normative beliefs, observational learning, behavioral skills and knowledge were found to be the predictors of physical activity. Reinforcement and punishment, normative beliefs, collective efficacy, social support and barriers and opportunities were the predictors of nutritional behaviors in the middle-aged population. As the results of the study showed, it is suggested to increase physical activity in the middle-aged population at risk of CAD using appropriate strategies to strengthen social support through family and friends, improve self-efficacy, identify positive and negative normative beliefs. Plans should be made to improve observational learning, increase behavioral skills, and increase knowledge to improve nutritional behaviors, use appropriate strategies to provide timely and appropriate rewards and punishments, identify and strengthen positive normative beliefs, improve collective efficacy, and increase social support. To this aim, families and other individuals around the middle-aged population can help remove barriers and create opportunities.

Hypertensive disorders of pregnancy and stroke: a univariate and multivariate Mendelian randomization study

Background

Hypertensive disorders of pregnancy (HDP) are associated with an increased risk of stroke later in life in multiparous women. However, causality of these associations remains unclear. This study employed 2-sample univariate and multivariate Mendelian randomization (MR) to assess the causal connection between HDP and stroke.

Methods

Genetic variants for HDP and two subtypes were identified from recent large-scale genome-wide association studies and the FinnGen consortium. Stroke summary data were obtained from the MEGASTROKE consortium. The primary analytical approach for univariate MR was the inverse variance weighting method. Sensitivity analyses incorporated methods such as MR-Egger regression, weighted median, and maximum likelihood to ascertain the robustness of the results. Additionally, multivariable MR analyses were conducted to account for potential associative effects of hypertension and type 2 diabetes.

Results

Genetically predicted HDP was associated with a high risk of large artery atherosclerosis (odds ratio [OR]=1.50, 95% confidence interval [CI]: 1.17-1.91, P=1.13×10-3) and small vessel stroke (OR=1.29, 95% CI: 1.20-1.50, P=1.52×10-3). HDP may also correlate with ischemic stroke (OR=1.13, 95% CI: 1.04-1.23, P=4.99×10-3) and stroke (OR=1.11, 95% CI: 1.03-1.20, P=8.85×10-3). An elevated risk of small vessel stroke (OR=1.20, 95% CI: 1.01-1.43, P=3.74×10-2) and large artery atherosclerosis (OR=1.22, 95% CI: 1.01-1.47, P=4.07×10-2) may be related with genetically predicted susceptibility to gestational hypertension. Genetically predicted susceptibility to preeclampsia or eclampsia may be associated with an increased risk of stroke (OR = 1.10, 95% CI: 1.02-1.19, P = 1.16×10-2) and ischemic stroke (OR = 1.10, 95% CI: 1.02-1.20, P = 1.84×10-2). Type 2 diabetes mellitus and hypertension were identified as significant factors contributing to the association between HDP and stroke.

Conclusions

This study provides genetic evidence supporting an association between HDP and increased stroke risk bolstering HDP as a cerebrovascular risk factor.

Knowledge about cardiovascular diseases in a first-level healthcare center in Lima, Peru

BACKGROUND

Motivation for the study. In Peru, the knowledge level of patients about their cardiovascular health is unknown at the first level of care, which receives 85% of the population, and where primary disease prevention activities are carried out.

BACKGROUND

Main findings. More than 70% of people had an inadequate level of knowledge about their own cardiovascular health.

BACKGROUND

Implications. Our results highlight the need to improve the education of people on cardiovascular health issues at the first level of care, taking into account that these diseases are increasingly frequent in the population.

BACKGROUND

This study aimed to determine the level of knowledge about cardiovascular diseases in people in a primary healthcare center (PHCC). A descriptive and cross-sectional study was carried out by surveying people who attended a PHCC in Lima, Peru. A score less than 6 was considered inadequate knowledge. A total of 400 people were surveyed, 66.3% were women and the mean age was 46.8 ± 16.2 years. The average score was 4.52 +/- 1.85. We found that 71% of those surveyed had an inadequate level of knowledge, regardless of age, gender or education level. Our findings show that the level of knowledge about risk factors and cardiovascular disease was inadequate in the primary care population. It is necessary to achieve proper specific education in cardiovascular risk factors in order to reduce the impact of these diseases.

Prevalence of Cardiovascular Disease and Comparison of Risk Category Predictions of Systemic Coronary Risk Evaluation Score-2 and 4 Other Cardiovascular Disease Risk Assessment Tools Among People Living with Human Immunodefficiency Virus in Türkiye

BACKGROUND

Cardiovascular disease (CVD) is a major cause of mortality among people living with HIV (PLWH). We aimed to assess the prevalence of diagnosed CVD and the risk of CVD among PLWH using 5 different tools.

METHODS

This retrospective, cross-sectional study was conducted in 20 tertiary centers in Türkiye between October 2021 and March 2022, among 1425 PLWH aged 40-75 years. About 82.7% were male, with a median age of 51. Web-based tools for each score were used for CVD risk calculations.

RESULTS

Of 1425 PLWH enrolled, 10.8% had confirmed CVD, and 1132 had their risk scores evaluated. Of those participants, 42.8% had a higher risk of CVD (10-year risk of atherosclerotic CVD risk score (ASCVD) above 7.5%), and according to the European Society of Cardiology systemic coronary risk evaluation 2 (SCORE2), 71.7% had a high- to very high-risk rate. The agreement between various CVD risk tools varied, with Framingham heart study risk score (FRS), modified FRS, data collection on adverse effects of anti-HIV drugs (DAD), and SCORE2 for high-risk countries showing overall agreement rates of 82%, 94%, 91%, and 36%, respectively, compared to ASCVD. According to the 2021 European and 2019 American Cardiology guidelines, 75.3% and 47.1% of PLWH would be eligible for lipid-lowering agents, respectively.

CONCLUSION

The diagnosed CVD prevalence highlighted the importance of monitoring cardiovascular health and comorbidities in this population. SCORE2 identified a greater number of individuals at high/very high risk compared to other prediction tools. The implementation of CVD prevention through lipid-lowering therapy was far from desired levels in our cohort.

Do Personalized Nutrition Interventions Improve Dietary Intake and Risk Factors in Adults With Elevated Cardiovascular Disease Risk Factors? A Systematic Review and Meta-analysis of Randomized Controlled Trials

CONTEXT

Dietary modifications can improve cardiovascular disease (CVD) risk factors. Personalized nutrition (PN) refers to individualized nutrition care based on genetic, phenotypic, medical, behavioral, and/or lifestyle characteristics. PN may be beneficial in improving CVD risk factors, including diet. However, this has not been reviewed previously.

OBJECTIVE

The aim was to evaluate the effectiveness of PN interventions on CVD risk factors and diet in adults at elevated CVD risk.

DATA SOURCES

Six databases were searched for randomized controlled trials published between 2000 and 2023 that tested the impact of PN interventions on CVD risk factors in people at elevated risk.

DATA EXTRACTION

Risk of bias was assessed using the Academy of Nutrition and Dietetics Quality Criteria checklist. Data synthesis of eligible articles included participant characteristics, intervention details, and change in primary CVD risk factor outcomes, including blood pressure (BP), plasma lipids, and CVD risk score, and secondary risk factors, including anthropometric outcomes and diet quality. Random-effects meta-analyses were conducted to explore weighted mean differences (WMDs) in change or final mean values for studies with comparable data (studies with dietary counseling interventions) for outcomes including BP, blood lipids, and anthropometric measurements.

DATA ANALYSIS

Of 7676 identified articles, 16 articles representing 15 studies met the inclusion criteria. Studies included between 40 and 563 participants and reported outcomes for CVD risk factors, including hyperlipidemia (n = 5), elevated BP (n = 3), overweight/obesity (n = 1), and multiple risk factors (n = 6). Risk of bias was low. Results suggested potential benefit of PN on systolic BP (WMD: -1.91; 95% CI: -3.51, -0.31 mmHg) and diastolic BP (WMD: -1.49; 95% CI: -2.39, -0.58 mmHg) and dietary intake in individuals at high CVD risk. Results were inconsistent for plasma lipid and anthropometric outcomes.

CONCLUSION

Results were promising for PN interventions that used dietary counseling on CVD risk factors in at-risk individuals. However, further evidence for other personalization methods is required, including improving methodological quality and longer study duration in future PN interventions.

Metabolic syndrome

The metabolic syndrome (MetS) is a multiplex modifiable risk factor for cardiovascular disease, type 2 diabetes mellitus and other health outcomes, and is a major challenge to clinical practice and public health. The rising global prevalence of MetS, driven by urbanization, sedentary lifestyles and dietary changes, underlines the urgency of addressing this syndrome. We explore the complex underlying mechanisms, including genetic predisposition, insulin resistance, accumulation of dysfunctional adipose tissue and ectopic lipids in abdominal obesity, systemic inflammation and dyslipidaemia, and how they contribute to the clinical manifestations of MetS. Diagnostic approaches vary but commonly focus on abdominal obesity (assessed using waist circumference), hyperglycaemia, dyslipidaemia and hypertension, highlighting the need for population-specific and phenotype-specific diagnostic strategies. Management of MetS prioritizes lifestyle modifications, such as healthy dietary patterns, physical activity and management of excess visceral and ectopic adiposity, as foundational interventions. We also discuss emerging therapies, including new pharmacological treatments and surgical options, providing a forward-looking perspective on MetS research and care. This Primer aims to inform clinicians, researchers and policymakers about MetS complexities, advocating for a cohesive, patient-centred management and prevention strategy. Emphasizing the multifactorial nature of MetS, this Primer calls for integrated public health efforts, personalized care and innovative research to address this escalating health issue.

Effect of aortic valve phenotype and sex on aorta dilation in patients with aortic stenosis

BACKGROUND

Bicuspid aortic valve (BAV) is often associated with a concomitant aortopathy. However, few studies have evaluated the effect of the aortic valve (AV) phenotype on the rate of dilation of the aorta. This study aimed to compare the progression rate of aorta dimensions according to AV phenotype (BAV vs tricuspid AV (TAV)), fusion type and sex in patients with aortic stenosis (AS).

METHODS

310 patients with AS (224 TAV and 86 BAV) recruited in the Metabolic Determinants of the Progression of Aortic Stenosis study (PROGRESSA, NCT01679431) were included in this analysis. Doppler echocardiography was performed annually to assess AS severity and measure ascending aorta (AA) dimensions. Baseline and last follow-up visit measurements were used to assess the annualised change.

RESULTS

Median AA annualised change was larger in BAV versus TAV (0.33±0.65 mm/year vs 0.21±0.56 mm/year, p=0.04). In the whole cohort, BAV phenotype and higher low-density lipoprotein (LDL) levels were significantly associated with fast progression of AA dilation in univariate analysis (OR 1.80, 95% CI 1.08 to 2.98, p=0.02; 1.37, 95% CI 1.04 to 1.80, p=0.03, respectively). AA dilation rate did not vary according to the BAV subtype (p=0.142). Predictors of AA progression rate were different between valve phenotypes, with higher apolipoprotein B/apolipoprotein A-I ratio, higher baseline peak aortic jet velocity (Vpeak) and smaller baseline AA diameter in the TAV cohort (all p<0.05) versus absence of hypertension, higher LDL levels and smaller baseline AA diameter in the BAV cohort (all p<0.02). In men, higher baseline Vpeak and smaller baseline AA (p<0.001) were independently associated with increased annualised AA dilation, while in women, higher LDL levels (p=0.026) were independently associated with faster AA dilation.

CONCLUSION

This study suggests that BAV is associated with faster dilation of the AA. Predictors of AA dilation are different between valve phenotype and sex, with higher LDL levels being associated with faster AA dilation in BAV.

Exploration of the relationship between general health-related problems and subclinical coronary artery disease: a cross-sectional study in a general population

OBJECTIVE

To explore associations between general health-related problems and subclinical coronary artery disease (CAD), determined by CT coronary calcium score (CT-CCS), in a general population.

DESIGN

A cross-sectional design.

SETTING

This study was performed in a prospective population-based cohort, examining the health and health-related behaviour of individuals living in the Northern Netherlands.

PARTICIPANTS

The initial cohort comprised 6763 participants ≥45 years of age who underwent CT-scanning. Participants were included for the current analysis if they filled in three validated questionnaires (Symptomatic Checklist-90, Research and Development Survey-36 and Reviving the Early Diagnosis of CardioVascular Diseases questionnaire (RED-CVD)) and did not have a history of cardiovascular disease. The final analysis included 6530 participants.

PRIMARY OUTCOME MEASURE

Backward-stepwise and forward-stepwise logistic regression analyses were performed to determine associations between general health-related problems and subclinical CAD (CCS≥100 and ≥300).

RESULTS

The median age was 53 years (25th, 75th percentile: 48, 58); 57% were women. CRCS≥100 was found in 1236 (19%) participants, 437 (12%) in women and 799 (29%) men and CCS≥300 in 643 (9.9%) participants of which 180 (4.8%) were women and 463 (16.6%) men. In univariate analysis, in women the expectation of health to worsen (OR=1.13, 95% CI: 1.05 to 1.21), and in men reduced exercise intolerance (OR=1.14, 95% CI: 1.06 to 1.23) were associated with CCS≥100. The total RED-CVD score in women (OR=1.06, (95% CI: 1.05 to 1.08) and men (OR=1.07, 95% CI: 1.06 to 1.09), and in men also reduced exercise intolerance (OR=1.15, 95% CI: 1.06 to 1.25) and headache (OR=0.55, 95% CI: 0.38 to 0.79) were associated with CCS≥300. In multivariate analyses, only general health expectation in women was still significantly associated with subclinical CAD (CCS≥300) (OR=1.92, 95% CI: 1.56 to 2.37).

CONCLUSION

Only a few general health-related problems were associated with the presence of subclinical CAD in the general population, however, these problems showed no strong association. Therefore, using health-related symptoms does not seem useful to pre-select for CT-CCS.

Association between dietary inflammatory index and all-cause mortality risk in adults with coronary heart disease in the United States

Diet and inflammation are crucial in the incidence and progression of coronary heart disease (CHD). This study aimed to investigate the correlation between the Dietary inflammatory index (DII) and all-cause mortality in CHD patients. A total of 1,303 CHD patients from the National Health and Nutrition Examination Survey (NHANES) between 2003 and 2018 were included. Multivariate Cox regression was used to explore the correlation between the DII and the risk of all-cause mortality in these patients. Restricted cubic spline (RCS) analysis was also utilized to examine the relationship between the DII and all-cause mortality risk in CHD patients. Additionally, subgroup analyses were conducted to determine how the correlation between the DII and all-cause mortality varied across different demographics. During a median follow-up period of 77 months among 1,303 CHD patients, 536 died from all causes. The DII scores were significantly higher in deceased patients compared to survivors. After adjusting for confounding factors, the multivariate Cox regression analysis indicated a strong positive correlation between the DII and all-cause mortality in CHD patients. RCS analysis suggested a non-linear relationship between the DII and all-cause mortality among CHD patients. Additionally, an increase in DII was more pronounced in its impact on female patients. The DII is strongly correlated with the risk of all-cause mortality among CHD patients, particularly among females. Thus, managing dietary inflammation is vital for the prevention and treatment of CHD, especially in female patients.

Information and Communications Technology-Based Monitoring Service for Tailored Chronic Disease Management in Primary Care: Cost-Effectiveness Analysis Based on ICT-CM Trial Results

BACKGROUND

Information and communications technology-based tailored management (TM) intervention is a novel automatic system in which a smartphone app for the management of patients with hypertension and diabetes, the provider web, and Bluetooth devices are linked. However, little evidence exists regarding the cost-effectiveness of the interventions using mobile apps.

OBJECTIVE

This study aimed to assess the cost-effectiveness of TM intervention for adult patients with hypertension or diabetes in primary care compared with usual care (UC).

METHODS

Cost-effectiveness analysis using a Markov model was conducted from the Korean health care system perspective. Based on 6-month outcome data from an information and communications technology-based tailored chronic disease management (ICT-CM) trial, effectiveness over a lifetime beyond the trial periods was extrapolated using a cardiovascular disease risk prediction model. Costs were estimated using ICT-CM trial data and national health insurance claims data. Health utility weights were obtained from the Korea National Health and Nutrition Examination Survey.

RESULTS

In the base-case analysis, compared with UC, TM was more costly (US $23,157 for TM vs US $22,391 for UC) and more effective (12.006 quality-adjusted life-years [QALYs] for TM vs 11.868 QALYs for UC). The incremental cost-effectiveness ratio was US $5556 per QALY gained. Probabilistic sensitivity analysis showed that the probability of TM being cost-effective compared with UC was approximately 97% at an incremental cost-effectiveness ratio threshold of US $26,515 (KRW 35 million) per QALY gained.

CONCLUSIONS

Compared with UC, TM intervention is a cost-effective option for patients with hypertension or diabetes in primary care settings. The study results can assist policy makers in making evidence-based decisions when implementing accessible chronic disease management services.

Inflammatory Trajectory of Type 2 Diabetes: Novel Opportunities for Early and Late Treatment

Low-grade inflammation (LGI) represents a key driver of type 2 diabetes (T2D) and its associated cardiovascular diseases (CVDs). Indeed, inflammatory markers such as hs-CRP and IL-6 predict the development of T2D and its complications, suggesting that LGI already increases before T2D diagnosis and remains elevated even after treatment. Overnutrition, unhealthy diets, physical inactivity, obesity, and aging are all recognized triggers of LGI, promoting insulin resistance and sustaining the pathogenesis of T2D. Once developed, and even before frank appearance, people with T2D undergo a pathological metabolic remodeling, with an alteration of multiple CVD risk factors, i.e., glycemia, lipids, blood pressure, and renal function. In turn, such variables foster a range of inflammatory pathways and mechanisms, e.g., immune cell stimulation, the accrual of senescent cells, long-lasting epigenetic changes, and trained immunity, which are held to chronically fuel LGI at the systemic and tissue levels. Targeting of CVD risk factors partially ameliorates LGI. However, some long-lasting inflammatory pathways are unaffected by common therapies, and LGI burden is still increased in many T2D patients, a phenomenon possibly underlying the residual inflammatory risk (i.e., having hs-CRP > 2 mg/dL despite optimal LDL cholesterol control). On the other hand, selected disease-modifying drugs, e.g., GLP-1RA, seem to also act on the pathogenesis of T2D, curbing the inflammatory trajectory of the disease and possibly preventing it if introduced early. In addition, selected trials demonstrated the potential of canonical anti-inflammatory therapies in reducing the rate of CVDs in patients with this condition or at high risk for it, many of whom had T2D. Since colchicine, an inhibitor of immune cell activation, is now approved for the prevention of CVDs, it might be worth exploring a possible therapeutic paradigm to identify subjects with T2D and an increased LGI burden to treat them with this drug. Upcoming studies will reveal whether disease-modifying drugs reverse early T2D by suppressing sources of LGI and whether colchicine has a broad benefit in people with this condition.

Acute Coronary Syndrome in Elderly Patients: How to Tackle Them?

Elderly patients diagnosed with acute coronary syndromes (ACS) represent a growing demographic population. These patients typically present more comorbidities and experience poorer outcomes compared to younger patients. Furthermore, they are less frequently subjected to revascularization procedures and are less likely to receive evidence-based medications in both the short and long-term periods. Assessing frailty is crucial in elderly patients with ACS because it can influence management decisions, as well as risk stratification and prognosis. Indeed, treatment decisions should consider geriatric syndromes, frailty, polypharmacy, sarcopenia, nutritional deficits, prevalence of comorbidities, thrombotic risk, and, at the same time, an increased risk of bleeding. Rigorous clinical assessments, clear revascularization criteria, and tailored approaches to antithrombotic therapy are essential for guiding personalized treatment decisions in these individuals. Assessing frailty helps healthcare providers identify patients who may benefit from targeted interventions to improve their outcomes and quality of life. Elderly individuals who experience ACS remain significantly underrepresented and understudied in randomized controlled trials. For this reason, the occurrence of ACS in the elderly continues to be a particularly complex issue in clinical practice, and one that clinicians increasingly have to address, given the general ageing of populations. This review aims to address the complex aspects of elderly patients with ACS to help clinicians make therapeutic decisions when faced with such situations.

Novel Biomarkers of Grade I Left Ventricular Diastolic Dysfunction in Type 2 Diabetes Patients with Metabolic-Dysfunction-Associated Steatotic Liver Disease

Background/Objectives: Prior research has identified a significant association between heart disease and metabolic-dysfunction-associated steatotic liver disease (MASLD); however, the underlying mechanisms are unclear. This study aimed to identify predictive biomarkers associated with grade I left ventricular diastolic dysfunction (LVDD) in patients with type 2 diabetes mellitus (T2DM). Methods: This single-center, cross-sectional study evaluated 73 T2DM patients for grade 1 LVDD and MASLD using 2D echocardiography, tissue analysis, spectral color Doppler, and Fibromax. Results: This study analyzed 50 patients (mean age 58.0 ± 11.3 years) with a median diabetes duration of 7 years, abdominal obesity (mean body mass index (BMI) 34.4 ± 5.9 kg/m2), and a mean HbA1c of 7.9 ± 1.5%. The prevalence of grade I LVDD, fibrosis, mild steatosis, moderate-to-severe liver steatosis, mild MASLD, and moderate MASLD was 54%, 44%, 14%, 80%, 43%, and 34%, respectively. Regression analysis revealed that grade 1 LVDD was positively associated with age, Fibrotest, α2-macroglobulin, epicardiac adipose tissue (EAT), and negatively associated with lateral s', E wave, E/e', E/A, medium E', and septal e' (p < 0.05 for all). α2-macroglobulin > 1.92 g/L (area under the receiver operating characteristic curve (AUROC) = 0.782, sensitivity 70.4%, specificity 81.2%) and fibrotest score > 0.11 (AUROC 0.766, sensitivity 92.6%, specificity 56.2%) were significant predictors of grade I LVDD. Conclusions: Although the underlying mechanisms remain unclear, innovative non-invasive biomarkers, such as α2-macroglobulin or fibrotest, could concurrently indicate liver stiffness and the likelihood of grade I LVDD, an early, asymptomatic HF stage in T2DM patients.

Race as a Risk Marker, Not a Risk Factor: Revising Race-Based Algorithms to Protect Racially Oppressed Patients

Emerging consensus in the medical and public health spheres encourages removing race and ethnicity from algorithms used in clinical decision-making. Although clinical algorithms remain appealing given their promise to lighten the cognitive load of medical practice and save time for providers, they risk exacerbating existing health disparities. Race is a strong risk marker of health outcomes, yet it is not a risk factor. The use of race as a factor in medical algorithms suggests that the effect of race is intrinsic to the patient or that its effects can be distinct or separated from other social and environmental variables. By contrast, incisive public health analysis coupled with a race-conscious perspective recognizes that race serves as a marker of countless other dynamic variables and that structural racism, rather than race, compromises the health of racially oppressed individuals. This perspective offers a historical and theoretical context for the current debates regarding the use of race in clinical algorithms, clinical and epidemiologic perspectives on "risk," and future directions for research and policy interventions that combat color-evasive racism and follow the principles of race-conscious medicine.

Development of a Concise Healthy Diet Score for Cardiovascular Disease among Japanese; The Japan Collaborative Cohort Study

AIMS

Several diet quality indicators have been developed primarily for cardiovascular disease (CVD) prevention in Western countries. However, those previous indicators are complicated and less feasible in clinical and health-promoting settings. Therefore, we aimed to develop a concise dietary risk score for CVD prevention in Japanese.

METHODS

Using the self-administered food frequency questionnaire with 35 food items, we developed a concise healthy diet score (cHDS) ranging from 0 to 5 points. We examined the association of cHDS with risks of all-cause and cause-specific mortality among 23,115 men and 35,557 women who were free of CVD and cancer.

RESULTS

During 19.2 years of median follow-up, 6,291 men and 5,365 women died. In men, the multivariable hazard ratios (95% confidence intervals) for the highest cHDS (5 points) compared to the lowest (0-1 points) were 0.74 (0.60-0.91, P-trend=0.008) for CVD and 0.86 (0.77-0.95, P-trend=0.05) for all causes. No significant associations were found for stroke, coronary heart disease, and other causes in men. The corresponding hazard ratio in women was 0.65 (0.52-0.81, P-trend＜0.001) for CVD, 0.63 (0.45-0.88, P-trend＜0.001) for stroke, 0.48 (0.30-0.78, P-trend=0.008) for coronary heart disease, 0.67 (0.54-0.84, P-trend＜0.001) for other causes, and 0.75 (0.66-0.85, P-trend＜0.001) for all causes.

CONCLUSION

We developed a concise diet quality score named cHDS in the Japanese population and found the inverse association of cHDS with mortality from CVD and all causes for both men and women.

Intraindividual Comparison of Ultrahigh-Spatial-Resolution Photon-Counting Detector CT and Energy-Integrating Detector CT for Coronary Stenosis Measurement

BACKGROUND

A recent simulation study proposed that stenosis measurements on coronary computed tomography (CT) angiography are influenced by the improved spatial resolution of photon-counting detector (PCD)-CT. The aim of the current study was to evaluate the impact of ultrahigh-spatial-resolution (UHR) on coronary stenosis measurements and Coronary Artery Disease Reporting and Data System (CAD-RADS) reclassification rates in patients undergoing coronary CT angiography on both PCD-CT and energy-integrating detector (EID)-CT and to compare measurements against quantitative coronary angiography.

METHODS

Patients with coronary calcification on EID-CT (collimation, 192×0.6 mm) were prospectively enrolled for a research coronary CT angiography with UHR PCD-CT (collimation, 120×0.2 mm) within 30 days (between April 1, 2023 and January 31, 2024). PCD-CT was acquired with the same or lower CT dose index and equivalent contrast media volume as EID-CT. Percentage diameter stenosis (PDS) for calcified, partially calcified, and noncalcified lesions were compared between scanners. Patient-level reclassification rates for CAD-RADS were evaluated. The accuracy of PDS measurements was validated against quantitative coronary angiography in patients who underwent invasive coronary angiography.

RESULTS

In total, PDS of 278 plaques were quantified in 49 patients (calcified, 202; partially calcified, 51; noncalcified, 25). PCD-CT-based PDS values were lower than EID-CT measurements for calcified (45.1±20.7 versus 54.6±19.2%; P<0.001) and partially calcified plaques (44.3±19.6 versus 54.9±20.0%; P<0.001), without significant differences for noncalcified lesions (39.1±15.2 versus 39.0±16.0%; P=0.98). The reduction in stenosis degrees led to a 49.0% (24/49) reclassification rate to a lower CAD-RADS with PCD-CT. In a subset of 12 patients with 56 lesions, UHR-based PDS values showed higher agreement with quantitative coronary angiography (mean difference, 7.3%; limits of agreement, -10.7%/25.2%) than EID-CT measurements (mean difference, 17.4%; limits of agreement, -6.9%/41.7%).

CONCLUSIONS

Compared with conventional EID-CT, UHR PCD-CT results in lower PDS values and more accurate stenosis measurements in coronary plaques with calcified components and leads to a substantial Coronary Artery Disease Reporting and Data System reclassification rate in 49.0% of patients.

Longitudinal Impacts of High Versus Low Greenness on Cardiovascular Disease Conditions

BACKGROUND

Greenness-or vegetative presence-has been identified as a factor in chronic disease. The present study examines the longitudinal relationship between objective measures of greenness at the residential block level and incidence of 6 cardiovascular disease conditions.

METHODS AND RESULTS

Analyses examined the impact of consistently high versus consistently low "precision" greenness at the Census block level on the 5-year incidence of cardiovascular disease conditions, including acute myocardial infarction, atrial fibrillation, heart failure, ischemic heart disease, stroke/transient ischemic attack, and hypertension, among 229 034 US Medicare beneficiaries in Miami-Dade County, Florida, USA. Zero-inflated Poisson regression was used to model the odds of developing any new cardiovascular disease and number of new cardiovascular disease conditions based on greenness tertiles computed across 2011 and 2016 Normalized Difference Vegetation Index values, adjusting for individual age, sex, race, ethnicity, baseline cardiovascular disease conditions, neighborhood income, and walkability in 2011 and 2016. When compared with individuals consistently in the low greenness tertile in 2011 and 2016, those consistently in the high greenness tertile in 2011 and 2016 had a 9% lower odds of having any new cardiovascular conditions (odds ratio [OR], 0.91 [95% CI, 0.84-0.99]; P=0.021).

CONCLUSIONS

Over a 5-year period, consistently high greenness, when compared with consistently low greenness, was associated with lower odds of any new cardiovascular disease conditions. Identifying the role of greenness exposure in such a small geographic area, the Census block on which the older adult resides, allows for more precise, strategic decisions on where additional trees can be added-by selecting at-risk blocks rather than entire neighborhoods for tree-planting interventions.

Major adverse cardiovascular events' reduction and their association with glucose-lowering medications and glycemic control among patients with type 2 diabetes: A retrospective cohort study using electronic health records

BACKGROUND

Cardiovascular diseases are a common cause of death among patients with type 2 diabetes (T2DM). Major adverse cardiovascular event (MACE) risks can be significantly reduced under adequate glycemic control (GC). This study aims to identify factors that influence MACE risk among patients with T2DM, including Hemoglobin A1c variability score (HVS) and early use of MACE-preventive glucose-lowering medications (GLMs).

METHODS

We conducted a longitudinal cohort study to retrospectively review electronic health records between 2011 and 2022. Patients with T2DM ≥18 years without previous stroke or acute myocardial infarction (AMI) were included. Cox regression was utilized to investigate MACE risk factors and compare MACE risk reduction associated with early use of MACE-preventive GLMs.

RESULTS

A total of 19 685 subjects were included, with 5431 having MACE, including 4453 strokes, 977 AMI, and 1 death. There were 11 123 subjects with good baseline GC. Subjects with good baseline GC had 0.837 (confidence interval [CI]: 0.782-0.895) times lower MACE risk than their counterpart. Subjects with a single MACE-preventive GLM at baseline with continuous use >365 days showed a decreased MACE hazard ratio (0.681; CI: 0.635-0.731). Among all MACE-preventive GLMs, semaglutide provided a more significant MACE-preventive effect.

CONCLUSIONS

This study identified that GLM, early GC, and HVS are MACE determinants among patients with T2DM. Novel GLM, adequate GC, and reduction of HVS can benefit MACE outcomes.

Current and Emerging Approaches for Primary Prevention of Coronary Artery Disease Using Cardiac Computed Tomography

PURPOSE OF REVIEW

To summarize the current use of cardiac computed tomography (CT) technologies as well as their pertinent evidence in regards to prevention of coronary artery disease (CAD).

RECENT FINDINGS

Cardiac CTA has now become a main non-invasive method for the evaluation of symptomatic CAD. In addition to coronary calcium score, other CT technologies such as atherosclerotic plaque analysis, fractional flow reserve estimation by CT, pericoronary fat attenuation, and endothelial wall shear stress have emerged. Whether the use of CT modalities can enhance risk prediction and prevention in CAD has not been fully answered. We discuss the evidence for coronary artery calcium scoring and coronary CT angiography in primary prevention and the current barriers to their use. We attempt to delineate what can be done to expand use and what studies are needed to broaden adoption in the future. We also examine the potential roles of emerging CT technologies. Finally, we describe potential clinical approaches to prevention that would incorporate cardiac CT technologies.

Effect of nuts on lipid profile and inflammatory biomarkers in atherosclerotic cardiovascular disease: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

Nut-enriched diets are related to improve lipid and inflammatory biomarkers in meta-analyses in the context of primary cardiovascular prevention. However, primary studies on secondary cardiovascular prevention are scarce and controversial. This systematic review and meta-analysis aimed to evaluate the effect of nut supplementation on lipid and inflammatory profiles in individuals with atherosclerotic cardiovascular disease, and the frequency of adverse events.

METHODS

Six databases were used for research: PubMed, EMBASE, BVS, Cochrane Library, Web of Science, and ClinicalTrials.gov, until February 2023, with no language restrictions. We performed random-effects meta-analyses to compare nut-enriched diets vs. control diets for pre-post intervention changes. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system assessed the evidence's certainty.

RESULTS

From the 5187 records identified, eight publications containing data referring to five randomized clinical trials involving 439 participants were included in the final analyses. The nuts evaluated were almonds, pecans, Brazil nuts, and mixed nuts, with doses ranging between 5 g and 85 g (median: 30 g/day). The intervention time varied between 6 and 12 weeks. Compared to nut-free diets, nut intake did not have a statistically significant effect on lipid profile biomarkers, except on the atherogenic index (MD: -0.32 [95% CI -0.58 to -0.06], I2 = 0% - moderate certainty of the evidence). Similarly, there was no effect of nuts on inflammatory profile biomarkers. It was not possible to aggregate data on adverse events.

CONCLUSIONS

Nut supplementation did not change lipid and inflammatory profiles in the secondary cardiovascular prevention setting.

Clinical Advances in Cardiovascular Computed Tomography: From Present Applications to Promising Developments

PURPOSE OF THE REVIEW

This review aims to provide a profound overview on most recent studies on the clinical significance of Cardiovascular Computed Tomography (CCT) in diagnostic and therapeutic pathways. Herby, this review helps to pave the way for a more extended but yet purposefully use in modern day cardiovascular medicine.

RECENT FINDINGS

In recent years, new clinical applications of CCT have emerged. Major applications include the assessment of coronary artery disease and structural heart disease, with corresponding recommendations by major guidelines of international societies. While CCT already allows for a rapid and non-invasive diagnosis, technical improvements enable further in-depth assessments using novel imaging parameters with high temporal and spatial resolution. Those developments facilitate diagnostic and therapeutic decision-making as well as improved prognostication. This review determined that recent advancements in both hardware and software components of CCT allow for highly advanced examinations with little radiation exposure. This particularly strengthens its role in preventive care and coronary artery disease. The addition of functional analyses within and beyond coronary artery disease offers solutions in wide-ranging patient populations. Many techniques still require improvement and validation, however, CCT possesses potential to become a "one-stop-shop" examination.

Investigating Factors Influencing Kidney Transplant Decisions in Patients on Chronic Hemodialysis: A Study at Shiraz University of Medical Sciences

OBJECTIVES

End-stage renal disease is a health concern around the world. Kidney transplant substantially improves survival compared with dialysis. Although kidney transplant is the better choice for treatment of end-stage renal disease, most patients refuse this option. In this study, we aimed to find the most common reasons why patients did not undergo a kidney transplant.

MATERIALS AND METHODS

We conducted a cross-sectional study involving 263 patients on chronic hemodialysis in hemodialysis centers in Shiraz, Iran, in 2024. We collected data via structured interviews, which had questions on demographics, disease characteristics, dialysis details, and reasons for transplant refusal. P < .05 was considered significant.

RESULTS

In our study cohort, mean age was 60.2 ± 16.8 years and 57.8% were male patients. The most prevalent reason for refusing kidney transplant was patient-centric barriers for kidney transplant (47.7%); difficulties with the transplant process included financial concern (33.7%), unacceptability of outcomes (30.2%), and worries about the unpredictability of transplant outcome (24.1%). The mean age of patients on the kidney transplant waiting list was 51.7 ± 16.4 years, and mean age of those who declined a kidney transplant was 60.2 ± 16.8 years (P < .001). Among patients on the waiting list, 68.7% were married compared with 81.7% of patients who declined a kidney transplant (P = .011).

CONCLUSIONS

Addressing financial concerns by possibly improving insurance coverage, enhancing patient education on transplant benefits and risks, and providing psychological support can potentially increase acceptance rates. Tailored interventions focusing on individual patient concerns and improving communication between health care providers and patients are essential.

Male Gender Expressivity and Diagnosis and Treatment of Cardiovascular Disease Risks in Men

Importance

Male gender expressivity (MGE), which reflects prevalent sociocultural pressures to convey masculinity, has been associated with health. Yet, little is known about associations of MGE with the diagnosis and treatment of modifiable cardiovascular disease (CVD) risks.

Objective

To investigate associations of MGE with modifiable CVD risk diagnoses and treatment in men.

Design, Setting, and Participants

This population-based cohort study included data from waves I (1994-1995), IV (2008-2009), and V (2016-2018) of the US National Longitudinal Study of Adolescent to Adult Health (Add Health). Participants were male adolescents (age 12-18 years) followed up longitudinally through younger adulthood (age 24-32 years) and adulthood (age 32-42 years). Data were analyzed from January 5, 2023, to August 28, 2024.

Exposure

Male gender expressivity was quantified in adolescence and younger adulthood using an empirically-derived and validated measurement technique that incorporates participants' responses to existing Add Health survey items to capture how similarly participants behave to same-gendered peers.

Main Outcomes and Measures

Outcomes included self-reported diagnoses of CVD risk conditions (hypertension, diabetes, or hyperlipidemia) in adult men with elevated blood pressure, hemoglobin A1c, or non-high-density lipoprotein cholesterol levels, and self-reported treatment with antihypertensive, hypoglycemic, or lipid-lowering medications in adults reporting hypertension, diabetes, or hyperlipidemia. Multivariable regression was used to examine associations of adolescent and younger adult MGE with adult CVD risk diagnoses and treatment, adjusting for sociodemographic covariates.

Results

Among 4230 eligible male participants, most were non-Hispanic White (2711 [64%]) and privately insured (3338 [80%]). Their mean (SD) age was 16.14 (1.81) years in adolescence, 29.02 (1.84) years in younger adulthood, and 38.10 (1.95) years in adulthood. Compared with participants whose younger adult MGE was below average, those with higher younger adult MGE were overall less likely to report hypertension (22% vs 26%; P < .001), diabetes (5% vs 8%; P < .001), and hyperlipidemia (19% vs 24%; P < .001) diagnoses and diabetes treatment (3% vs 5%; P = .02) as adults. In multivariable models, every SD increase in adolescent MGE was associated with lower probabilities of adult hypertension treatment (MGE,-0.11; 95% CI, -0.16 to -0.6) and diabetes diagnoses (MGE, -0.15; 95% CI, -0.27 to -0.03). Higher younger adult MGE was associated with lower probabilities of adult hypertension diagnoses (MGE, -0.04; 95% CI, -0.07 to -0.01), hypertension treatment (MGE, -0.07; 95% CI, -0.13 to -0.01), and diabetes treatment (MGE, -0.10; 95% CI, -0.20 to -0.01). Adolescent and younger adult MGE outcomes were not associated with other adult CVD outcomes.

Conclusions and Relevance

In this cohort study of US males, higher adolescent and younger adult MGE was associated with lower adult hypertension and diabetes diagnoses and treatment. These findings suggest that males with high MGE may bear distinctive risks and correspondingly benefit from tailored public health efforts to prevent downstream CVD.

Flaxseed Lowers Blood Pressure in Hypertensive Subjects: A Meta-Analysis of Randomized Controlled Trials

This systematic review and meta-analysis study aimed to evaluate the effectiveness of flaxseed supplementation on blood pressure (BP) in patients with hypertension based on the data from randomized clinical trials (RCTs). Three databases (PubMed [MEDLINE], Scopus, and ISI Web of Science) were searched from inception up to August 10, 2024. Relevant studies meeting our eligibility criteria were obtained. A random-effects model was used to estimate pooled weighted mean differences (WMDs) with 95% confidence intervals (CIs). The methodological quality of individual studies was assessed using the Cochrane Collaboration risk of bias tool. A total of 5 studies were included and analyzed using STATA software version 12. The results show that there is a significant decrease in systolic BP (WMD, -8.64 mmHg; 95% CI, -15.41 to -1.87; p ≤ 0.001) and diastolic BP (WMD, -4.87 mmHg; 95% CI, -8.37 to -1.37; p = 0.006) of patients with hypertension as compared to control groups. This study supported that flaxseed supplementation had favorable effects on BP control in hypertensive patients. It may be a promising adjuvant therapy for patients with hypertension.

Role of the screening with coronary computed tomography angiography on lipid management and risk factors control in an asymptomatic Chinese population: a community-based, parallel-group, open-label, randomized clinical trial (RESPECT2)

BACKGROUND

Lipid management based on cardiovascular risk level is the cornerstone of primary prevention of coronary artery disease (CAD), while the accuracy and adherence of traditional cardiovascular risk stratification have been questioned. Prevention strategies based on imaging screening for atherosclerotic plaques are found to be more objective and adherent in recent studies. This trial aims to investigate the role of coronary computed tomography angiography (CCTA) in guiding the primary prevention of CAD in a randomized controlled design.

METHODS

Approximately 3400 middle-aged asymptomatic community participants will be recruited and randomized in a 1:1 ratio to a traditional cardiovascular risk score-guided (usual care group) or CCTA-guided (CCTA group) strategy. Participants with cardiovascular disease, prior lipid-lowering therapy, CCTA contraindication, or serious diseases that affect life span will be excluded. The intervention strategy includes blood pressure, blood glucose, and lipid management and lifestyle modifications. Blood pressure and glucose targets and lifestyle modification recommendations keep the same in both strategies, while lipid management is personalized based on traditional risk level or CCTA results, respectively. The primary outcome is the proportion of participants taking lipid-lowering medication regularly at both 6 and 12 months. The secondary outcomes include the proportion of participants achieving low-density lipoprotein cholesterol lowering targets at 12 months, mean changes in lipid levels from baseline to 12 months, barriers to adherence, adverse reactions related to CCTA examination, and cardiovascular events.

DISCUSSION

The study is the first randomized clinical trial to examine the effectiveness of a CCTA-guided versus a traditional risk score-guided primary prevention strategy in an asymptomatic community-based population.

The Impact of Flavonoid Supplementation on Serum Oxidative Stress Levels Measured via D-ROMs Test in the General Population: The PREVES-FLAVON Retrospective Observational Study

BACKGROUND

Oxidative stress has emerged as a key contributor to numerous NCDs (non-communicable diseases), including cardiovascular diseases, cancer, and diabetes. This study aims to explore the potential of targeted interventions to mitigate oxidative stress as part of a primary prevention strategy.

METHODS

The study included 32 healthy participants (11 men, 21 women) aged 45-65 who completed both the initial and follow-up assessments of the Healthy Days Initiative, a community-based wellness program organized by the non-profit Associazione O.R.A. ETS. Through blood analysis, vital sign assessment, lifestyle questionnaires, and individualized recommendations, participants received guidance on improving their health and reducing disease risk. The initiative also offered the opportunity for participants to consume a flavonoid supplement containing quercitrin, rutin, and hesperidin, with the goal of reducing oxidative stress. Participants who opted for supplementation were instructed to take 1-2 tablets daily for two weeks. Data collected included demographic information, anthropometric measurements, vital signs, dietary and lifestyle habits, medical history, WHO-5 Well-Being Index scores, and blood parameters.

RESULTS

Significant reductions were observed in glucose levels (from 82 to 74.5 mg/dL), reactive oxygen metabolites (d-ROMs) (from 394.5 to 365.5 U.CARR), and systolic blood pressure (from 133 to 122 mmHg) after the two-week flavonoid intervention. Most participants (26/31) reported no side effects, and the majority (30/31) expressed a willingness to continue using a product combination of quercitrin, rutin, and hesperidin or a similar product long-term.

CONCLUSIONS

While limited in scope and duration, the PREVES-FLAVON study contributes valuable insights to the growing body of evidence suggesting that flavonoid supplementation may play a significant role in reducing risk factors associated with NCDs in primary prevention settings. By targeting novel risk factors such as oxidative stress, this intervention holds promise for mitigating the global burden of NCDs and promoting healthy aging.

Detection of cardiovascular disease cases using advanced tree-based machine learning algorithms

Cardiovascular disease (CVD) can often lead to serious consequences such as death or disability. This study aims to identify a tree-based machine learning method with the best performance criteria for the detection of CVD. This study analyzed data collected from 9,499 participants, with a focus on 38 different variables. The target variable was the presence of cardiovascular disease (CVD) and the villages were considered as the cluster variable. The standard tree, random forest, Generalized Linear Mixed Model tree (GLMM tree), and Generalized Mixed Effect random forest (GMERF) were fitted to the data and the estimated prediction power indices were compared to identify the best approach. According to the analysis of important variables in all models, five variables (age, LDL, history of cardiac disease in first-degree relatives, physical activity level, and presence of hypertension) were identified as the most influential in predicting CVD. Fitting the decision tree, random forest, GLMM tree, and GMERF, respectively, resulted in an area under the ROC curve of 0.56, 0.73, 0.78, and 0.80. The GMERF model demonstrated the best predictive performance among the fitted models based on evaluation criteria. Regarding the clustered structure of the data, using relevant machine-learning approaches that account for this clustering may result in more accurate predicting indices and targeted prevention frameworks.
