Work-Related Stress Is Associated With Unfavorable Cardiovascular Health: The Multi-Ethnic Study of Atherosclerosis.

Work-related stress is a psychosocial risk factor linked to a higher risk of cardiovascular disease. However, the association between work-related stress and cardiovascular health (CVH) is not well established. We estimated the association between work-related stress and CVH in a multiethnic sample of adults free of cardiovascular disease at baseline. We performed a cross-sectional analysis of 3579 community-based men and women, aged 45 to 84 years, of the Multi-Ethnic Study of Atherosclerosis from data collected between 2000 and 2002. Work-related stress (yes/no) was assessed by a self-administered questionnaire. CVH was measured by the American Heart Association's Life's Simple 7 metrics (smoking, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose). Each metric contributed 0, 1, or 2 points if in the poor, intermediate, or ideal range, respectively. The aggregated CVH score was 0 to 14 points and categorized as inadequate (0-8 points), average (9-10 points), and optimal (11-14 points). Polytomous logistic regression was used to estimate the association between work-related stress and CVH, adjusting for sociodemographic factors. The mean±SD age was 57±8 years, and 48% were women. Work-related stress was reported by 20% of participants. In fully adjusted models, participants with work-related stress had lower odds of having average (adjusted odds ratio [OR], 0.75 [95% CI, 0.62-0.92]) and optimal (adjusted OR, 0.73 [95% CI, 0.58-0.92]) CVH scores compared with participants without work-related stress. Work-related stress was associated with unfavorable CVH. These findings underscore the importance of workplace psychological well-being and suggest the need for studies on interventions that may reduce work-related stress and promote CVH.

Assessment of Lifetime Risk for Cardiovascular Disease: Time to Move Forward.

Over the past decades, there has been a notable increase in the risk of Cardiovascular Disease (CVD), even among younger individuals. Policymakers and the health community have revised CVD prevention programs to include younger people in order to take these new circumstances into account. A variety of CVD risk assessment tools have been developed in the past years with the aim of identifying potential CVD candidates at the population level; however, they can hardly discriminate against younger individuals at high risk of CVD.Therefore, in addition to the traditional 10-year CVD risk assessment, lifetime CVD risk assessment has recently been recommended by the American Heart Association/American College of Cardiology and the European Society of Cardiology prevention guidelines, particularly for young individuals. Methodologically, the benefits of these lifetime prediction models are the incorporation of left truncation observed in survival curves and the risk of competing events which are not considered equivalent in the common survival analysis. Thus, lifetime risk data are easily understandable and can be utilized as a risk communication tool for Public Health surveillance. However, given the peculiarities behind these estimates, structural harmonization should be conducted in order to create a sex-, race-specific tool that is sensitive to accurately identifying individuals who are at high risk of CVD. In this review manuscript, we present the most commonly used lifetime CVD risk tools, elucidate several methodological and critical points, their limitations, and the rationale behind their integration into everyday clinical practice.

PCGmix: A Data-Augmentation Method for Heart-Sound Classification.

Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide, responsible for 32% of all deaths, with the annual death toll projected to reach 23.3 million by 2030. The early identification of individuals at high risk of CVD is crucial for the effectiveness of preventive strategies. In the field of deep learning, automated CVD-detection methods have gained traction, with phonocardiogram (PCG) data emerging as a valuable resource. However, deep-learning models rely on large datasets, which are often challenging to obtain. In recent years, data augmentation has become a viable solution to the problem of scarce data. In this paper, we propose a novel data-augmentation technique named PCGmix, specifically engineered for the augmentation of PCG data. The PCGmix algorithm employs a process of segmenting and reassembling PCG recordings, incorporating meticulous interpolation to ensure the preservation of the cardinal diagnostic features pertinent to CVD detection. The empirical assessment of the PCGmix method was utilized on a publicly available database of normal and abnormal heart-sound recordings. To evaluate the impact of data augmentation across a range of dataset sizes, we conducted experiments encompassing both limited and extensive amounts of training data. The experimental results demonstrate that the novel method is superior to the compared state-of-the-art, time-series augmentation. Notably, on limited data, our method achieves comparable accuracy to the no-augmentation approach when trained on 31% to 69% larger datasets. This study suggests that PCGmix can enhance the accuracy of deep-learning models for CVD detection, especially in data-constrained environments.

Environmental Heavy Metal Exposure and Associated Cardiovascular Diseases in Light of the Triglyceride Glucose Index.

Cardiovascular diseases (CVD), primarily ischemic heart disease and stroke, remain leading global health burdens. Environmental risk factors have a major role in the development of CVD, particularly exposure to heavy metals. The Triglyceride Glucose Index (TyG), a measure of insulin resistance and CVD risk, is the primary focus of this study, which summarizes the most recent findings on the effects of lead (Pb), arsenic (As), and cadmium (Cd) on CVD risk. A higher risk of CVD is correlated with an elevated TyG index, which has been linked to insulin resistance. Exposure to Cd is associated with disturbance of lipid metabolism and oxidative stress, which increases the risk of CVD and TyG. Exposure reduces insulin secretion and signaling, which raises the TyG index and causes dyslipidemia. Pb exposure increases the risk of CVD and TyG index via causing oxidative stress and pancreatic β-cell destruction. These results highlight the need of reducing heavy metal exposure by lifestyle and environmental modifications in order to lower the risk of CVD. To comprehend the mechanisms and create practical management plans for health hazards associated with heavy metals, more study is required.

Endothelial dysfunction markers syndecan-1 and thrombomodulin are associated with higher albuminuria levels in type 2 diabetes with no history of clinical cardiovascular disease

IntroductionIndividuals with type 2 diabetes and increased albuminuria, a well-established marker of microvascular complications, are at a higher risk for cardiovascular disease (CVD) and premature mortality. Therefore, a better understanding of the underlying pathophysiology is needed to improve risk stratification and tailor prevention and intervention. MethodsWe conducted a cross-sectional study including 463 individuals with type 2 diabetes, various degrees of albuminuria and without CVD. We analysed the association between albuminuria and markers of endothelial function (thrombomodulin and syndecan-1), thrombin generation (thrombin-antithrombin complex, prothrombin fragment 1 + 2), fibrinogen, platelet function (activation using soluble plasma selectin and aggregation using Multiplate® Analyzer) using regression models. ResultsIn the study cohort 33 % were women, the mean ± SD age was 65 ± 9 years, and median [IQR] diabetes duration was 15 [9–20] years. In total, 344 (74 %) individuals had normal albuminuria, 87 (19 %) moderately- and 32 (7 %) severely increased albuminuria levels. Higher markers of endothelial function and fibrinogen were independently associated with higher albuminuria levels (p < 0.01). No association between albuminuria and markers of thrombin generation and platelet was demonstrated. ConclusionWe demonstrated an independent association between albuminuria and markers of endothelial function and fibrinogen in individuals with type 2 diabetes and no history of CVD.

'A potentially ticking time bomb' - barriers for prevention, diagnosis, and treatment of cardiovascular disease in people with intellectual disabilities.

Research suggests that people with intellectual disabilities have a higher risk for cardiovascular disease than the general population. The aim of this study was to identify barriers for the prevention, diagnosis, and treatment of cardiovascular disease for people with intellectual disabilities. We conducted individual interviews with relatives and general practitioners and focus group interviews with staff working at an assisted home facility, a cardiac ward, an obesity clinic and two rehabilitation centres (n = 33) in Norway. Inductive approach and thematic analysis were used to analyse the data. We identified barriers on an individual and a structural level. The underlying reason for these barriers is that health problems, such as cardiovascular disease, are regularly overlooked as the condition of intellectual disability overshadows other possible diagnoses. This focus on intellectual disability rather than other explanations leads to shortcomings in the prevention, diagnoses, and treatment of cardiovascular disease in this group.

Impact of smoking cessation on metabolic parameters and renal function in patients with and without diabetes mellitus.

As patients with diabetes are at a significantly higher risk of cardiovascular diseases than those without diabetes, it is important to gain a clinical understanding of the differential effects of smoking cessation on several risk factors between patients with and without diabetes. Patients who participated in a smoking cessation program received an assessment of the outcomes of interest. The outcomes were changes in metabolic parameters and renal function from baseline to 6-month follow-up after the smoking cessation program. A total of 1,954 patients joined the smoking cessation program, and 1,381 patients were in the smoking cessation failure (SCF) group and 573 were in the smoking cessation success (SCS) group. The decrease in HbA1c after smoking cessation was only observed in patients with diabetes. Smoking cessation was also associated with a significant decrease in LDL cholesterol in patients with diabetes. In terms of renal function, smoking cessation was associated with an improvement in eGFR, and the trend was similar in patients with and without diabetes. Successful smoking cessation was associated with improvement in renal function. Moreover, it was associated with improvements in HbA1c and LDL cholesterol in patients with diabetes, despite significant weight gain.

Hospitalization after hydroxychloroquine initiation in patients with heart failure with preserved ejection fraction and autoimmune disease.

Hydroxychloroquine (HCQ) reduces cardiovascular events among patients with autoimmune disorders and is being evaluated as a therapeutic option for populations with high-risk cardiovascular disease. However, recent studies have raised concerns about HCQ use and cardiovascular events. To assess the association of HCQ initiation with heart failure-related and all-cause hospitalizations among patients with heart failure and preserved ejection fraction (HFpEF). We conducted a cohort study of patients aged ≥18 years with diagnosed HFpEF and autoimmune disease using MarketScan Commercial and Medicare Supplemental databases (2007-2019). Patients were required to initiate HCQ after their first HFpEF diagnosis (HCQ users) or not (HCQ nonusers). For the patients in the HCQ users group, the first HCQ prescription date was assigned as the index date. Index date for the HCQ nonuser group was assigned by prescription-time distribution matching HCQ users, by utilizing the number of days from HFpEF diagnosis to the first HCQ prescription. After 1:≥3 propensity score (PS) matching, Cox proportional hazards regression models were used to compare HF-related and all-cause hospitalizations between users and nonusers. After PS matching, 2229 patients (592 HCQ users and 1637 HCQ nonusers) were included. After controlling for covariates, patients who received HCQ had lower risks of HF-related hospitalization (adjusted hazard ratio, 0.44; 95% CI, 0.24-0.82) and all-cause hospitalization (adjusted hazard ratio, 0.69; 95% CI, 0.57-0.83) compared with patients not using HCQ. Among patients with HFpEF and autoimmune disease, initiation of HCQ use was associated with a decreased risk of HF-related and all-cause hospitalizations.

10-Year Atherosclerotic Cardiovascular Disease (ASCVD) Risk Score Calculation in Out-Patient Department

Objective: To calculate 10-year Atherosclerotic Cardiovascular Disease risk score in outdoor department of a tertiary care hospital and identify individuals at high risk of cardiovascular disease. Study Design: Cross-sectional study. Place and Duration of Study: Combined Military Hospital, Malir, Pakistan, from Oct 2020 to Mar 2021. Methodology: 116 patients presenting to Out-Patient Department of General Medicine of CMH, Malir, Pakistan, without previous evidence of cardiovascular disease were included. Previous history of diabetes, smoking, use of anti-hypertensives, Aspirin and statins was recorded. Systolic and diastolic blood pressures, waist circumference, HbA1c, fasting blood sugar, fasting LDL, HDL and total cholesterol were tested for each patient. 10-year ASCVD risk score was calculated using online ASCVD Risk Estimator calculator. Results: Mean age of the patients was 58.6±9.92 years with 62.1% being males and 37.9% being females. Mean 10-year ASCVD risk score was 13.37±7.1, of which 21 patients (18.1%) had Very High, 66(56.9%) had Intermediate and 29(25%) had Low 10-year ASCVD risk score. Among Very High cases, 80.9% were males, all were in age group 50-79 years, 61.9% were diabetic, 33.3% were smokers and 66.7% were obese. Conclusion: A very high percentage of study group had Intermediate or Very High 10-year ASCVD risk score. Identifying those individuals at high risk early and controlling the modifiable risk factors can help lessen the morbidity and mortality associated with cardiovascular diseases.

Factors influencing health-promoting behavior among single mothers in Northeastern Malaysia: a cross-sectional study.

Health-promoting behaviors (HPB) play a vital role in maintaining and enhancing overall well-being. Single mothers are at higher risk of cardiovascular disease (CVD) and less involvement in HPB due to psychosocial disadvantages. This study aimed to determine the HPB scores and factors influencing HPB among single mothers in Kelantan (Northeastern, Malaysia). This study employed a cross-sectional design, selecting 242 single mothers from Kelantan through proportional stratified sampling. Data were gathered through questionnaires covering sociodemographic details, the Health-Promoting Lifestyle Profile-II (HPLP-II), the Malay Version of Health Beliefs Related to Cardiovascular Disease (HBCVD-M), and Multidimensional Perceived Social Support (MPSS). The relationships between the dependent variable (HPB) and independent variables were analyzed using multivariable linear regression models. The respondents achieved an average HPB score of 118.03 (SD = 19.2), with the highest mean scores in spiritual growth (22.46 [SD = 3.70]) and interpersonal relationships (22.05 [SD = 3.67]). Physical activity had the lowest mean score at 15.09 (SD = 4.62). Significant positive associations were found between HPB and perceived severity of CVD (adjusted β = 1.60; 95% CI [0.68-2.53]; p<0.001) as well as perceived social support (adjusted β = 0.63; 95% CI [0.37-0.90]; p<0.001). Conversely, educational level (adjusted β = -10.36; 95% CI [-16.06 to -4.67]; p<0.001) and perceived benefits of reducing CVD risk (adjusted β = -1.43; 95% CI [-2.37 to -0.48]; p<0.001) were negatively associated with HPB. The findings highlight the importance of health beliefs, social support, and education in shaping HPB among single mothers. Community health initiatives targeting this population should develop strategies to strengthen individuals' health beliefs and promote a supportive environment.

Cardiovascular Risks With SGLT2 Inhibitors in Clinical Practice Among Patients With Type 2 Diabetes

Cardiovascular disease (CVD) can be recurrent during type 2 diabetes (T2D) progression in this aging population. The effectiveness of sodium-glucose cotransporter 2 inhibitor (SGLT2i) therapy on total (ie, first and subsequent) CVD among patients with T2D in clinical practice remains uncertain. To analyze the comparative association of SGLT2i vs dipeptidyl peptidase 4 inhibitor (DPP4i) therapy with total CVD among patients with T2D in clinical practice. This retrospective cohort study used electronic medical records at the National Cheng Kung University Hospital, a leading medical center in Taiwan, from 2015 through 2021. Adult patients with T2D who initiated first use of the study drugs from 2016 through 2019, with up to 6 years of follow-up, were identified. The primary outcomes included total composite CVD events and individual CVD subtypes (ie, atrial fibrillation, coronary heart disease, heart failure, stroke, myocardial infarction, and transient ischemic attack). A shared frailty model analysis was used to assess the association of treatment with repeat CVD events. Data from patients at high risk for CVD recurrence were further analyzed. Data were analyzed from September 1, 2022, to December 31, 2023. Overall, 8384 patients with T2D were identified (mean [SD] age, 63.7 [12.4] years; 4645 [55.4%] male). A total of 1632 propensity score-matched pairs of SGLT2i (mean [SD] age, 57.8 [12.0] years; 673 [41.2%] female and 959 [58.8%] male) and DPP4i (mean [SD] age, 58.2 [12.9] years; 655 [40.1%] female and 977 [59.9%] male) users were included. SGLT2i was associated with reduced total CVD risk vs DPP4i therapy (hazard ratio [HR], 0.82 [95% CI, 0.69-0.98]) but not the first CVD event (with the use of SGLT2i therapy were more prominent for patients at high risk of CVD (ie, HR, 0.70 [95% CI, 0.62-0.80] for individuals with estimated glomerular filtration rate lower than 60 mL/min/1.73 m2; HR, 0.70 [95% CI, 0.64-0.78]; for individuals having any diabetes-related complications; and HR, 0.72 [95% CI, 0.65-0.80] for individuals with a history of CVD) compared with the overall cohort. Among patients at high risk of CVD, greater reduced total CVD burden associated with SGLT2i therapy was observed for women vs men (eg, HR, 0.59 [95% CI, 0.49-0.72] in the subgroup with CVD history). In this cohort study of patients with T2D, the use of SGLT2is vs DPP4is was associated with reduced total cardiovascular burden, suggesting that long-term use of this therapy may optimize treatment benefit among patients with chronic CVD. The SGLT2i-associated benefit among patients with high risk of CVD encourages the prioritization of SGLT2i use for these vulnerable individuals.

Association of estimated glucose disposal rate with incident cardiovascular disease under different metabolic and circadian rhythm states: findings from a national population-based prospective cohort study

BackgroundRecent studies have shown that both metabolic syndrome and circadian rhythm syndrome are firmly associated with the occurrence of cardiovascular disease (CVD), with insulin resistance playing a significant role. The estimated glucose disposal rate (eGDR) is considered to be a reliable surrogate marker for insulin resistance. However, the relationship between eGDR and CVD under different metabolic and circadian rhythm states has not been thoroughly studied, and large-scale prospective cohort studies are needed to clarify this relationship.MethodsThis study is based on the China Health and Retirement Longitudinal Study (CHARLS), recruiting individuals aged 45 and above with complete eGDR data. The eGDR was calculated by the formula: eGDR(mg/kg/min) = 21.158 − (0.09 × WC) − (3.407 × hypertension) − (0.551 × HbA1c) [WC (cm), hypertension (yes = 1/no = 0), and HbA1c (%)] (Zabala et al. in Cardiovasc Diabetol 20(1):202; 2021).Participants were divided into four subgroups based on the quartiles (Q) of eGDR.The cumulative incidence rates and hazard ratios (HR) with 95% confidence intervals (CI) were calculated, with the lowest eGDR quartile (representing the highest degree of insulin resistance) as the reference. Participants were further divided into subgroups based on the diagnosis of Metabolic syndrome (MetS) or circadian syndrome (CircS) to explore the relationship between eGDR and CVD under different metabolic and circadian rhythm conditions. The dose–response relationship between eGDR and CVD incidence was investigated using a restricted cubic spline (RCS) based on a Cox regression model. Receiver operating characteristic (ROC) curves were generated to assess the predictive value of eGDR for CVD incidence. A clinical decision curve analysis (DCA) was also conducted to assess the clinical utility of the basic model.Results6507 participants were included, with a median age of 58 years [52 years, 64 years], and 55% were female. Over a median follow-up duration of 87 months, 679 first-episode CVD events were recorded, including heart disease and stroke. The RCS curves demonstrated a significant dose–response relationship between eGDR and the incidence of first-presentation CVD in different metabolic and circadian rhythm subgroups (all P-values < 0.001, non-linearity P > 0.05). eGDR exhibited a significant linear relationship with all outcomes (non-linearity P < 0.05). The Kaplan–Meier cumulative incidence curves showed that as eGDR levels increased, the cumulative incidence rates of first CVD, heart disease, and stroke gradually decreased from Q1 to Q4 groups. Significant differences were observed across all metabolic and circadian rhythm subgroups (log-rank test P < 0.001). Through the Cox proportional hazards model, we confirmed a significant association between baseline eGDR levels and first-onset CVD, heart disease, and stroke. Subgroup analyses indicated that the predictive ability of eGDR for CVD risk varied across different Body mass index (BMI) (P for interaction = 0.025) and age (P for interaction = 0.045) subgroups. Mediation analysis revealed that CircS partially mediated this association. Furthermore, time-dependent ROC curves demonstrated the potential of eGDR as a predictor of CVD risk, revealing possible differences in the model's application across different cardiovascular conditions.ConclusioneGDR is an independent predictor of CVD risk, with lower eGDR levels being closely associated with a higher risk of CVD (including heart disease and stroke). In populations with MetS or CircS, the association between lower eGDR levels and increased risk is more pronounced.

Association between high versus low cardiovascular risk in individuals with corresponding unexpected absent versus severe subclinical coronary atherosclerosis, a nationwide, multicenter study

Abstract Background It remains unclear as to why some individuals at low risk of cardiovascular disease (CVD) develop severe coronary atherosclerosis, while those at high CVD risk may remain free from coronary atherosclerosis. Purpose Using Coronary Computed Tomography Angiography (CCTA), we aimed to identify factors associated with absence and severe coronary atherosclerosis in subjects from the general population with very high and low-moderate CVD risk, respectively. Methods We assessed cross-sectionally a nationwide, multicenter population-based cohort, consisting of 30,154 individuals randomly recruited from the general population (age range 50-64 years, 51.4% women). Coronary calcified plaque burden was estimated by coronary artery calcium score (CACS) assessed by CCTA. Absent coronary atherosclerosis was defined as CACS 0 and severe coronary atherosclerosis was defined as CACS ≥301. We investigated only individuals with low-moderate (&amp;lt;5%) and very high CVD risk (≥10%) according to SCORE2 were included. Individuals with CACS 0 and prevalent CVD were excluded, as well as those with moderate CACS (1-300) or SCORE2 risk 5-9%. Out of 26 722 subjects with complete data on CACS and SCORE2, 13 075 were included. Logistic regression was performed adjusted for age and sex. Results The overall distribution of CACS in relation to SCORE2 CVD risk is illustrated in the Figure. Study characteristics are displayed in Table 1. Severe-extensive CACS in combination with low-moderate CVD risk was present in 2.3% (n=296). A further 2.3% (n=311) had very high CVD risk but CACS 0. Factors associated with CACS 0 despite a very-high estimated CVD risk included: lower age, being female, being born in Sweden, not having hypertension or hyperlipidemia, fewer pack-years of smoking, and lower waist circumference in men. On the contrary, severe-extensive CACS despite a low-moderate estimated CVD risk was associated with higher age, being male, being an ex-smoker, reporting more pack-years of smoking, having higher HbA1c, higher BMI, higher waist circumference, and prevalent hyperlipidemia and hypertension (Table 2). Conclusions We identified extreme cardiovascular risk phenotypes (subgroups) in the general population that either lacked coronary calcifications despite being at very high estimated CVD risk or had severe subclinical coronary atherosclerosis despite being at estimated low-moderate CVD risk. Further studies are warranted to elucidate putative enhancing or protective mechanisms explaining this unexpected phenomenon.

Association of COVID-19 and influenza vaccinations and cardiovascular drugs with hospitalisation and mortality in COVID-19 and Long COVID: 2-year follow-up of 17 million individuals in England

Abstract Introduction For COVID-19 and Long COVID, determining the highest-risk subgroups, particularly in the context of compound pressures such as influenza and cardiovascular disease (CVD), may identify effective interventions to prevent adverse health outcomes, and inform public health and policy decisions. Methods Using national, linked electronic health records for England (NHS England Secure Data Environment: via CVD-COVID-UK/COVID-IMPACT Consortium), we studied individuals with COVID-19 and Long COVID from January 2020 to February 2023. We compared all-cause hospitalisation and mortality in unmatched and matched cohort analyses, by prior CVD, high CVD risk (by QRISK2), COVID-19 and influenza vaccination status, and prescription of CVD preventive therapies. We investigated potential impact of targeted vaccination and CVD prevention strategies on mortality and hospitalisations by calculating population preventable fractions. Results We identified 17,373,850 individuals with COVID-19 [54.4% female; mean age 38.8 years; COVID-19 vaccination ≥2 doses:50.0%, influenza vaccination (≥1 dose):27.8%; mean follow-up 1.28 years] and 301,115 with Long Covid [61.8% female; mean age 46.0 years; COVID-19 vaccination ≥2 doses:66.4%, influenza vaccination:33.1%; mean follow-up 1.1 years]. Hospitalisation and mortality rates were 15.3% and 2.0% in COVID-19 (Long COVID rate 1.3%) and 16.8% and 1.4% in Long COVID, respectively. Adjusted risk of mortality and hospitalisation were reduced with COVID-19 vaccination ≥2 doses (COVID-19:HR 0.36, 95% CI 0.34-0.38 and 0.69, 0.68-0.69; Long COVID:0.44, 0.42-0.47 and 0.90, 0.89-0.91). With influenza vaccination, mortality was reduced, but not hospitalisation (COVID-19: 0.86, 0.85-0.86 and HR 1.01, 1.01-1.01, and Long COVID: 0.72, 0.67-0.76, and 1.05, 1.03-1.07), with greatest effect in those with prior CVD and high CVD risk. Mortality and hospitalisation were also reduced by CVD prevention in those with CVD, e.g. anticoagulants- COVID-19: 0.69, 0.69-0.70 and 0.92, 0.91-0.93; Long Covid: 0.59, 0.54-0.64, and 0.88, 0.84-0.92. COVID-19 vaccination, influenza vaccination and CVD drugs (Anticoagulants) averted 101117 of 193598, 2138 of 4017 and 16573 of 36847 preventable deaths among individuals after COVID-19, and 875 of 1189, 65 of 127 and 507 of 1007 preventable deaths among those with Long COVID, particularly in people with CVD. Conclusions Prior CVD and high CVD risk are associated with increased hospitalisation and mortality risk in people with COVID-19 and Long COVID. Targeted improvement in COVID-19 vaccination and CVD prevention, especially in those with CVD are priority interventions in pandemics to avoid excess hospitalisation and mortality.Baseline Characteristics and OutcomesHospitalisation/mortality by COVID vaccn

Sex differences in cardiovascular disease in relation to socioeconomic position in the NAKO study

Abstract Background Low socioeconomic position (SEP) is associated with cardiovascular disease (CVD) risk; yet, the underlying pathways are not fully clear and may affect sexes differently. We investigated sex differences in the relationship of SEP with prevalent CVD, cardiovascular risk factors (CRF) and estimated cardiovascular risk in a contemporaneous German population. Methods Data derived from the baseline examination of 204,780 participants in population-based German National Cohort (NAKO). Logistic, multinomial, and linear regression models were used to estimate sex-specific odds ratios (OR) and beta-coefficients with 95% confidence intervals (CI) of CVD, CRF and very high-risk score (SCORE2 ≥7.5% (age 40-49 years) or ≥ 10% (age 50-69 years)) associated with educational attainment and relative income. Women-to-men ratios of ORs (RORs) with 95%-CI were estimated. Results In women compared to men, low vs. high SEP was more strongly associated with obesity, overweight, self-reported myocardial infarction and hypertension, elevated blood pressure values, antihypertensive medication, and alcohol consumption, but less strongly related to smoking. In women with the lowest vs. highest educational level, the OR for a very high 10-year CVD risk was 3.61 (95%-CI 2.88; 4.53), compared to 1.72 (95%-CI 1.51; 1.96) in men. The women-to-men-ROR was 2.33 (95%-CI 1.78; 3.05), attenuated after age-adjustments. For the comparison of low vs. high relative income, the odds of having a very high 10-year CVD risk was 2.55 (95%-CI 2.04; 3.18) in women, and 2.25 (95%-CI 2.08; 2.42) in men (women-to-men ROR, 1.31 (95%-CI 1.05; 1.63). Conclusions In both sexes, there was an inverse graded relationship between SEP and the likelihood of prevalent CVD and CRF, with stronger associations in women than in men. Although women had a lower estimated 10-year CVD risk compared to men, the likelihood of having a very high CVD risk conferred by low SEP vs. a high one was higher in women than in men.

Cost-Effectiveness of Salt Substitution and Antihypertensive Drug Treatment in Chinese Prehypertensive Adults.

Recent guidelines recommend antihypertensive drug treatment for prehypertensive individuals with blood pressure between 130/80 and 139/89 mm Hg. This study evaluates the cost-effectiveness of 3 interventions in Chinese prehypertensive adults: salt substitution, antihypertensive drug treatment, and their combination. We developed a Markov cohort model to estimate cardiovascular disease (CVD) events, costs, and quality-adjusted life years (QALYs) over a lifetime. Data from the China Kadoorie Biobank informed the simulation. Costs and utilities were drawn from published sources. We evaluated the cost-effectiveness of salt substitution alone, antihypertensive drug treatment alone, and a combination of the 2, focusing on the overall prehypertensive population, those at high CVD risk, and different starting ages (40, 50, 60, and 70 years). Incremental cost-effectiveness ratios (ICERs) were calculated per QALY gained. Salt substitution at age 40 years is the only cost-effective strategy for prehypertensive individuals, with an ICER of $6413.62/QALY. For those at high CVD risk, the combination intervention starting at age 40 years is most cost-effective, with an ICER of $2913.30/QALY. Interventions initiated at younger ages yielded greater CVD reductions and lower ICERs. For example, a combined intervention at age 40 years reduces CVD events by 5.3% with an ICER of $2913.30/QALY, compared with 4.9% and $32 635.33/QALY at age 70 years. These results were consistent across sensitivity analyses. In China, replacing usual salt with a salt substitute is more cost-effective than treating prehypertensive individuals over the age of 40 years with antihypertensive drugs. Furthermore, starting intervention at a younger age in prehypertensive adults can result in even greater cost savings.

Rurality and outcomes in prostate cancer: role of socioeconomic status and educational attainment

Abstract Background/Introduction Patients diagnosed with prostate cancer (PC) have a higher cardiovascular disease (CVD) prevalence and mortality risk. Rurality have been associated with up to 33% higher CVD risk and 44% higher all-cause mortality risk in patients with PC. Purpose Analyze the impact of rurality (from both patient and provider perspectives) on the development of adverse outcomes after a PC diagnosis according to socioeconomic and educational status. Methods We included men aged ≥66 with a new primary PC diagnosis (defined as ICD-10 = C61) from 2009-2017 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. The primary outcomes were CVD (comprising heart failure, atrial fibrillation, acute myocardial infarction, peripheral artery disease, and ischemic stroke), PC-specific mortality (PCsm), cardiovascular disease mortality (CVDm), and all-cause mortality. Patients living in areas with a population of &amp;lt;2,500 or &amp;lt;20,000, not adjacent to a metropolitan area, were considered to have a positive rural status. The provider status (metropolitan vs. non-metropolitan) was defined according to the 2013 National Center for Health Statistics' Urban-Rural Classification Scheme for Counties. Low socioeconomic status (SES) was defined according to Yost Index quintiles. Low educational status was defined according to percentiles of people &amp;gt;25 years old with less than a high school diploma. Multivariable Fine-Gray models, accounting for competing mortality/type of mortality, and Cox regression models were applied. Results We included 75,221 patients with PC (Picture 1), of which 1,828 were from rural areas and 362 were from rural areas with providers from non-metropolitan areas. Among patients from rural areas under the care of non-metropolitan providers, 82.6% had low SES (Yost Index ≤ 2). In this subgroup, patients from rural areas with non-metropolitan providers had 30% higher CVD risk (sHR 1.30; 95% CI 1.04-1.62) and 44% higher all-cause mortality risk (sHR 1.44; 95% CI 1.14-1.83; Picture 2) when compared to patients with low SES from urban or rural areas with providers from metropolitan areas. Additionally, within patients from rural areas with non-metropolitan providers, the median % of people with only high school diploma was 38.3 (IQR 36.2-40.9). Among those with low educational status (≤41% of high school county-rate), patients from rural areas with non-metropolitan providers had a 35% higher associated CVD risk (sHR 1.35; 95% CI 1.06-1.71), 54% higher associated CVDm risk (sHR 1.54; 95% CI 1.01-2.36), and a 32% higher associated all-cause mortality risk (sHR 1.32; 95% CI 1.04-1.66). Conclusion Patients with PC from rural areas with non-metropolitan providers have higher rates of low SES and low educational status and suffer from up to 54% higher associated risks of adverse outcomes, emphasizing the role of multiple domains of the Social Determinants of Health in health outcomes.

Impact of bundled payments on healthcare use and costs for cardiovascular diseases in the Netherlands

Abstract Background Bundled payments for patients with cardiovascular diseases (CVD) aim to enhance primary care utilization in the Netherlands. This study assesses changes in healthcare utilization patterns and costs for CVD between 2015 and 2019, while investigating the potential association with bundled payment adoption. Methods We studied patients at very high risk for CVD using routinely recorded nationwide healthcare data. Multilevel logistic- and gamma regressions were conducted to assess healthcare utilizations patterns between 2015 and 2019, and the impact of bundled payments on the likelihood of receiving medical specialist care and the height of associated costs. Results The odds of medical specialist involvement declined over time for the 148,876 patients included in our study. This decline was significantly associated with practices’ use of bundled payments. Medical specialist costs did also significantly decrease between 2015 and 2019, and patients in practices with the highest level of bundled payments had significantly lower medical specialist costs. When general practice costs were included however, healthcare costs per patient stayed the same, both over time and stratified by use of bundled payments. Conclusions Our findings suggest an association between bundled payments and specialized healthcare use, potentially facilitating the transition to primary care. While we found no evidence for costs savings, our findings do support a reduction in spending growth. Key messages • We evaluated the impact of bundled payments as a means to facilitate integrated care, and found that bundled payments were associated with lower uptake of specialized medical care. • We found no cost savings were found, but findings do support reduced spending growth.

Cardiovascular events risk in office-masked nocturnal hypertension defined by home blood pressure monitoring: the J-HOP nocturnal blood pressure study

Abstract Background Elevated nocturnal home blood pressure (BP) has been reported to be associated with increased risk for cardiovascular disease (CVD). Masked hypertension defined by home BP monitoring is also a strong risk factor for adverse CVD outcomes. However, no study has investigated the association between office-masked nocturnal hypertension defined by home BP monitoring and CVD events risk. Purpose This study aimed to examine the association between office-masked nocturnal hypertension defined by home BP monitoring and CVD events risk in a clinical practice-based population. Methods This was a prospective observational study including Japanese participants with CVD or high risk of CVD. Three office BPs were taken on two different occasions. Nocturnal home BP was measured three times per night for two weeks. The association between office-masked nocturnal hypertension and incident total CVD events (including fatal and non-fatal stroke and coronary heart disease) was examined using Cox regression. Results 2,545 participants were followed for the mean of 7.1 years (18,116 person-years), during which 152 (6.0%) CVD events occurred. Mean age (standard deviation) was 63.3 (10.3) years; 49.0% were male; 82.6% took antihypertensive medications. The proportions of participants with normotension (office BP &amp;lt;140/90 mmHg and nocturnal home BP &amp;lt;120/70 mmHg), white-coat hypertension (office BP ≥140/90 mmHg and nocturnal home BP &amp;lt;120/70 mmHg), office-masked nocturnal hypertension (office BP &amp;lt;140/90 mmHg and nocturnal home BP ≥120/70 mmHg), and sustained hypertension (office BP ≥140/90 mmHg and nocturnal home BP ≥120/70 mmHg) were 25.3%, 14.4%, 23.2%, and 37.1%, respectively. The office-masked nocturnal hypertensive group and sustained hypertensive group had higher incidence rates of total CVD events compared with the normotensive group. Relative to normotension, those with both office-masked nocturnal hypertension (adjusted hazard ratio [aHR] 1.72, 95% confidence interval [CI] 1.01–2.92) and sustained hypertension (aHR 1.75, 95%CI 1.03–2.96) had similarly increased CVD risk, even after adjustment for daytime home BP values. Conclusions Screening for office-masked nocturnal hypertension with home BP monitoring identifies a potentially important group of patients with increased risk for incident CVD events for whom additional preventative measures may be appropriate.

Arrhythmogenic effects of DEHP exposure: insights into cardiac electrophysiology and myocardial cells

Abstract Introduction Hemodialysis patients, who are exposed to plasticizers through the hemodialysis circuit, face a high risk of cardiovascular disease (CVD). Plasticizers, such as the endocrine-disrupting compound Di(2-ethylhexyl) phthalate (DEHP), have emerged as potential contributors to CVD. This study explores the impact of DEHP on cardiac electrophysiology and myocardial cells, providing insights into its cardiotoxic effects. Methods We employed optical mapping techniques to assess cardiac electrophysiology in Langendorff-perfused rat hearts exposed to DEHP, comparing them to a control group. Additionally, we evaluated the effect of DEHP on cardiac muscle cells using H9C2 rat cardiomyoblasts. Results Prolonged DEHP exposure resulted in elevated heart rate, increased electrocardiographic variability, and higher low-frequency values, indicative of sympathetic nervous system overactivity. Action potential duration at APD80 increased, leading to greater action potential triangulation. Electrical alternans observed in the DEHP-treated group heightened the risk of arrhythmias. Single-cell analysis revealed severe mitochondrial damage, myocardial cell apoptosis, and disrupted calcium ion balance. Conclusion This study highlights DEHP's cardiotoxicity, suggesting its potential role in arrhythmogenesis and cardiac dysfunction. Environmental pollutants like DEHP warrant consideration as contributors to cardiovascular diseases, emphasizing the need for further research on preventive strategies.
