Epidemiological trends and age-period-cohort effects on cardiovascular diseases burden attributable to ambient air pollution across BRICS

Long-term exposure to ambient air pollution raises the risk of deaths and morbidity worldwide. From 1990 to 2019, we observed the epidemiological trends and age-period-cohort effects on the cardiovascular diseases (CVD) burden attributable to ambient air pollution across Brazil, Russia, India, China, and South Africa (BRICS). The number of CVD deaths related to ambient particulate matter (PM) pollution increased nearly fivefold in China [5.0% (95% CI 4.7, 5.2)] and India [5.7% (95% CI 5.1, 6.3)] during the study period. The age-standardized CVD deaths and disability-adjusted life years (DALYs) due to ambient PM pollution significantly increased in India and China but decreased in Brazil and Russia. Due to air pollution, the relative risk (RR) of premature CVD mortality (< 70 years) was higher in Russia [RR 12.6 (95% CI 8.7, 17.30)] and India [RR 9.2 (95% CI 7.6, 11.20)]. A higher period risk (2015–2019) for CVD deaths was found in India [RR 1.4 (95% CI 1.4, 1.4)] followed by South Africa [RR 1.3 (95% CI 1.3, 1.3)]. Across the BRICS countries, the RR of CVD mortality markedly decreased from the old birth cohort to young birth cohorts. In conclusion, China and India showed an increasing trend of CVD mortality and morbidity due to ambient PM pollution and higher risk of premature CVD deaths were observed in Russia and India.

Association of major and minor ECG abnormalities with traditional cardiovascular risk factors in the general population: a large scale study

Cardiovascular disease (CVD) can be determined and quantified using the electrocardiogram (ECG) analysis. Identification of the risk factors associated with ECG abnormalities may advise prevention approaches to decrease CVD burden. In this study we aimed to investigate the association between CVD risk factors and minor and major ECG abnormalities in a general Iranian adult population. This study was conducted in 2010 and covered a population of 9035 males and females aged 35 to 65 years recruiting from the phase I of Mashhad Stroke and Heart Atherosclerotic Disorder (MASHAD) cohort study. The participants were drawn by a stratified cluster random sampling technique. The Bivariate and multinomial logistic regression analysis were conducted considering gender stratification to explore the association of ECG abnormalities with traditional cardiovascular risk factors. There was a significant association between minor and major ECG abnormalities and hypertension (HTN), type 2 diabetes (T2DM), smoking, and physical activity (p < 0.005). There was a significant trend, in both genders, for increasing major abnormalities as the number of CVD risk factors increased. But, only in women, the minor abnormalities increase in frequency as the number of CVD risk factors increased. The results of multinomial logistic regression showed that men with HTN [ARRR = 1.25, 95% CI 0.99, 1.57] and T2DM [ARRR = 1.31, 95% CI 0.99, 1.74] had the highest likelihood to have major abnormalities, although these are not statistically significant. For women, those with HTN had the highest likelihood to have major [ARRR = 1.36, 95% CI 1.13, 1.63] and minor [ARRR = 1.35, 95% CI 1.15, 1.58] abnormalities. Also, women aged > 60 years were more likely to have major [ARRR = 2.01, 95% CI 1.49, 2.74] and minor [ARRR = 1.59, 95% CI 1.20, 2.10] abnormalities compared to women aged < 45 years. Age and HTN were significantly associated with major and minor ECG abnormalities in women, and, on the other hand, HTN and T2DM were associated with major abnormalities in men. Taken together, these findings suggest that healthcare providers should advise preventive approaches to the asymptomatic adults with both major and minor electrocardiographic abnormalities that may predict cardiovascular risk.

PCI Vs. CABG: Battle For Better Outcomes in Pakistani Triple Vessel Disease Patients

Background: Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide, with Triple Vessel Disease (TVD) representing a severe form that poses significant treatment challenges. In Pakistan, the burden of CVDs is high, exacerbated by genetic and lifestyle factors. Objective: To evaluate and compare the clinical outcomes of Percutaneous Coronary Intervention (PCI) and Coronary Artery Bypass Grafting (CABG) in patients diagnosed with Triple Vessel Disease (TVD) in a Pakistani cohort. Methods: This prospective cohort study was conducted at Lady Reading Hospital, Peshawar, from January 1, 2020, to December 31, 2021. A total of 400 patients diagnosed with TVD based on angiographic findings were enrolled. Inclusion criteria included age above 18 years, clinical diagnosis of stable angina or non-ST elevation myocardial infarction, and consent to participate. Exclusion criteria were previous revascularization procedures, concomitant valvular or congenital heart disease, and life expectancy less than a year due to non-cardiac conditions. Patients were assigned to either PCI or CABG based on clinical decisions by their managing cardiologists, considering anatomical considerations, comorbid conditions, and patient preferences. Baseline demographic and clinical data, including age, gender, smoking status, presence of diabetes, hypertension, and previous myocardial infarction (MI), were collected through patient interviews and medical record reviews. Clinical outcomes were monitored for 12 months post-procedure. Primary outcome measures included mortality, myocardial infarction, repeat revascularization, and stroke within 12 months. Secondary outcomes were hospital readmission rates and quality of life scores, measured using a standardized 10-point scale. Statistical analyses were performed using SPSS version 25, with continuous variables expressed as means and standard deviations and categorical variables as percentages. The chi-square test or Fisher’s exact test was used for categorical outcomes, and the student’s t-test or Mann-Whitney U test for continuous outcomes, with a p-value of less than 0.05 considered statistically significant. Results: The mean age of the participants was 62.5 ± 7.8 years, with 62 ± 8 years in the PCI group and 63 ± 7 years in the CABG group (p=0.45). Gender distribution was similar, with 255 males and 145 females overall (p=0.55). Smoking status, diabetes, hypertension, and previous MI were comparably distributed between the groups. Mortality was 5% in the PCI group and 3% in the CABG group (p=0.31). Myocardial infarction occurred in 10% of PCI patients compared to 5% of CABG patients (p=0.05). Repeat revascularization was required in 15% of the PCI group versus 7% of the CABG group (p=0.01). Stroke incidence was 2% in the PCI group and 1% in the CABG group (p=0.45). Hospital readmission rates were 20% for PCI and 15% for CABG (p=0.10). Quality of life scores were higher in the CABG group (8.0 ± 1.1) compared to the PCI group (7.5 ± 1.2) (p=0.04). Conclusion: CABG may offer superior outcomes compared to PCI in managing TVD among Pakistani patients, particularly in reducing myocardial infarction rates and repeat revascularization. Despite the invasive nature of CABG, its long-term benefits suggest it should be considered preferentially for patients with complex coronary anatomies. Clinical decisions should, however, be tailored to individual patient factors and preferences.

Epidemiology of cardiovascular diseases related admissions in a tertiary hospital in Hadramout Governorate, Yemen

Background: Cardiovascular diseases (CVDs) are a major challenge confronting physicians in Hadramout Governorate. Little is known about the admission for CVD and outcome at Hadramout Modern Hospital. The aim of this study was to determine the frequency and pattern of CVD admissions in Hadramout Modern Hospital, Hadramout, Yemen. Materials and Methods: This retrospective cross-sectional study included all adult patients admitted for CVDs in the medical ward of Hadramout Modern Hospital from January 01 to December 31, 2023. Results: During the study period, a total of 1020 patients were admitted to the medical word, of which 158 (15.5%) cases were admitted with CVDs. There were 87 (55.1%) males, and the mean age was 58.09±15.08 years. There was a significant age difference between men and women (61.4 years vs. 54.04 years, p=0.002). The most commonly affected age group was those aged 55–64 (32.4%). Uncontrolled hypertension (81.6%), stroke (52.5%), heart failure (37.3%), and acute myocardial infarction (AMI) (36.1%) were the most common CVDs. The mean hospital stay was 7.93±2.83 (2–15 days). There were 220 total deaths in Hadramout Modern Hospital during the study period. Among them, 12 (5.5%) were due to CVDs with no significant sex difference (4 [5.6%] vs. 8 [9.2%]; p=0.549). Conclusion: Given the increasing burden of CVDs in our hospital, it is crucial to understand the epidemiological features of CVDs and their etiological factors to prioritize further research, prevention, and treatment strategies. Additionally, further research is needed in other governorates across the country to identify regions with the highest regional burden of CVDs so that policymakers can reallocate limited resources accordingly.

Acute coronary syndrome in young (≤45 Years) patients: a multicenter observational study

Introduction: Acute Coronary Syndrome (ACS) in young individuals (≤45 y) is increasingly recognized as a significant health concern, yet research in this demographic remains limited, particularly within the Palestinian context. This study aims to bridge this gap by comprehensively investigating the clinical characteristics, age-specific profiles, gender disparities, treatment modalities, and angiographic patterns of ACS in young patients compared to their older counterparts. Materials and Methods: A multicenter observational study was conducted, enrolling 468 participants aged 18-55 diagnosed with ACS and admitted to three prominent Palestinian hospitals. Data were collected from medical records, and statistical analysis was performed to assess demographic characteristics, clinical presentations, risk factors, treatment strategies, and outcomes. Results: The majority of participants were male (87%), with a higher proportion in the older age group (&gt;45 y). Clinical presentations varied, with Non-ST Segment Elevation Myocardial Infarction (NSTEMI) being the most common diagnosis (48%). Risk factors such as smoking, hypertension, and diabetes were prevalent, with notable gender and age-specific differences. Percutaneous Coronary Intervention (PCI) was the predominant treatment strategy (83%), with consistent medication use across age groups. Conclusion: ACS in young patients poses a significant public health challenge in Palestine, necessitating tailored preventive strategies and comprehensive management approaches. Understanding the unique demographic and clinical characteristics of young ACS patients is crucial for informing targeted interventions and policies aimed at reducing the burden of cardiovascular disease in this population. These findings contribute valuable insights to the existing literature and underscore the importance of further research in this area to improve outcomes and mitigate the impact of ACS in young individuals globally.

Metal mixture exposures and serum lipid levels in childhood: the Rhea mother-child cohort in Greece.

Growing evidence suggests that cardiovascular disease develops over the lifetime, often beginning in childhood. Metal exposures have been associated with cardiovascular disease and important risk factors, including dyslipidemia, but prior studies have largely focused on adult populations and single metal exposures. To investigate the individual and joint impacts of multiple metal exposures on lipid levels during childhood. This cross-sectional study included 291 4-year-old children from the Rhea Cohort Study in Heraklion, Greece. Seven metals (manganese, cobalt, selenium, molybdenum, cadmium, mercury, and lead) were measured in whole blood using inductively coupled plasma mass spectrometry. Serum lipid levels included total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol. To determine the joint and individual impacts of child metal exposures (log2-transformed) on lipid levels, Bayesian kernel machine regression (BKMR) was employed as the primary multi-pollutant approach. Potential effect modification by child sex and childhood environmental tobacco smoke exposure was also evaluated. BKMR identified a positive association between the metal mixture and both total and LDL cholesterol. Of the seven metals examined, selenium (median 90.6 [IQR = 83.6, 96.5] µg/L) was assigned the highest posterior inclusion probability for both total and LDL cholesterol. A difference in LDL cholesterol of 8.22 mg/dL (95% CI = 1.85, 14.59) was observed when blood selenium was set to its 75th versus 25th percentile, holding all other metals at their median values. In stratified analyses, the positive association between selenium and LDL cholesterol was only observed among boys or among children exposed to environmental tobacco smoke during childhood. Growing evidence indicates that cardiovascular events in adulthood are the consequence of the lifelong atherosclerotic process that begins in childhood. Therefore, public health interventions targeting childhood cardiovascular risk factors may have a particularly profound impact on reducing the burden of cardiovascular disease. Although growing evidence supports that both essential and nonessential metals contribute to cardiovascular disease and risk factors, such as dyslipidemia, prior studies have mainly focused on single metal exposures in adult populations. To address this research gap, the current study investigated the joint impacts of multiple metal exposures on lipid concentrations in early childhood.

Temporal trends in the contribution of modifiable cardiovascular risk factors to cardiovascular and all-cause mortality in patients undergoing myocardial perfusion imaging in a large city in Brazil

BackgroundMost cardiovascular (CV) events stem from modifiable, but it remains uncertain whether their impact on mortality has decreased in recent years as a result of treatment, particularly in low- and middle-income countries. We evaluated the temporal trends in the population attributable fraction (PAF) of modifiable risk factors to CV mortality in patients undergoing myocardial perfusion imaging (MPI) for suspected coronary artery disease in a large city in Brazil. MethodsThe cohort comprised 25,127 patients without established CV disease undergoing MPI in a referral center in Curitiba, Brazil, from 2010 to 2018. Baseline demographic, clinical and risk factors were prospectively collected. Modifiable risk factors encompassed hypertension, dyslipidemia, diabetes mellitus, sedentary lifestyle, obesity, and smoking. The primary outcome was CV death occurring up to 4 years of follow-up. The PAF of each risk factor was calculated for each triennium using multivariable Cox proportional regression models, adjusting for age, sex and family history of premature coronary disease. ResultsOver 9 years, there were 1438 deaths, 444 due to CV causes. In the first triennium, sedentary lifestyle exhibited the highest PAF (49%) for CV death, followed by hypertension (17%), diabetes mellitus (8%) and smoking habit (6%). The PAF for all risk factors combined remained relatively stable thorough the triennia (2010–2012: 57% vs 2013–2015: 64% vs 2016–2018: 47%, p = NS). ConclusionIn this large cohort of patients referred to MPI, the PAF of modifiable CV risk factors did not diminish in the last decade, with sedentary lifestyle having the largest contribution for CV mortality. Condensed abstractThis study examinated temporal trends in the impact of modifiable cardiovascular (CV) risk factors on CV and overall mortality in a cohort of 25,127 patients undergoing myocardial perfusion imaging from 2010 to 2018. Sedentary behavior consistently had the greatest impact on both CV and overall mortality, followed by hypertension and diabetes. Smoking had a lesser effect, while obesity showed no independent association with the outcomes. The contributions of these modifiable CV risk factors remained stable over the study period, suggesting that interventions promoting physical activity may be essential in mitigating the burden of CV disease.

The Burden of Cardiovascular Disease attributable to High Fasting Plasma Glucose：Findings From the Global Burden of Disease Study 2019

AimHigh fasting plasma glucose (HFPG) is a key risk factor for cardiovascular disease (CVD). Few studies have evaluated the CVD burden attributable to HFPG globally. It is urgent to investigate the current epidemiological pattern and past trends of CVD attributable to HFPG. MethodsWe used the Global Burden of Disease Study (GBD) 2019 to describe the CVD burden attributable to HFPG in 2019 and evaluate temporal trends between 1990 and 2019. ResultsGlobal Disability-Adjusted Life Years (DALYs) cases and death cases of HFPG-related CVD were approximately 72,591,163 and 3,763,298 in 2019, with an increase of 107.4% and 114.6% compared with 1990, respectively. Despite the increases, the age-standardized DALYs rate (ASDAR) and age-standardized death rate (ASDR) of HFPG-related CVD contributed to 895.2 per 100,000 people and 48.4 per 100,000 people in 2019, with an estimated annual percentage change (EAPC) of ﹣0.22 and ﹣0.31, respectively, from 1990. The highest ASDAR and ASDR of HFPG-related CVD were in 2019 observed in the low-middle‐SDI (Socio‐demographic Index) and middle‐SDI regions. Low‐SDI and some low-middle‐SDI regions showed an increase in ASDAR and ASDR of HFPG-related CVD from 1990 to 2019. Males are more affected by HFPG-related CVD than females across all years. The CVD burden attributable to HFPG in the elderly are higher than those in the young in 2019. The main causes of the global CVD burden attributable to HFPG in 2019 were ischemic heart disease, stroke, and peripheral arterial disease. ConclusionThe CVD burden attributable to HFPG remains a serious public health challenge threatening human health worldwide. It is necessary to develop more targeted and specific strategies to reduce CVD burden attributable to HFPG, especially in males, elderly, and lower SDI regions.

Gender equality in medical research: A cardiology-informed examination

Despite a perceived increase in attention to gender differences in medicine, a comprehensive assessment of gender equality research, particularly in cardiology, remains underexplored. This observational retrospective study, focusing on documents related to "Gender Equality" according to the Sustainable Development Goals, reveals cardiology as a significant area for gender equality research, albeit with a decline in publications post-2018. The analysis highlighted a concentrated effort in the United States and a considerable impact gap between gender-focused and general cardiology research. The global academic community must intensify research into gender disparities, which is essential for achieving professional gender equality and addressing the burden of cardiovascular diseases.

International Migration and Cardiovascular Health: Unraveling the Disease Burden Among Migrants to North America and Europe.

Europe and North America are the 2largest recipients of international migrants from low-resource regions in the world. Here, large differences in cardiovascular disease (CVD) morbidity and death exist between migrants and the host populations. This review discusses the CVD burden and its most important contributors among the largest migrant groups in Europe and North America as well as the consequences of migration to high-income countries on CVD diagnosis and therapy. The available evidence indicates that migrants in Europe and North America generally have a higher CVD risk compared with the host populations. Cardiometabolic, behavioral, and psychosocial factors are important contributors to their increased CVD risk. However, despite these common denominators, there are important ethnic differences in the propensity to develop CVD that relate to pre- and postmigration factors, such as socioeconomic status, cultural factors, lifestyle, psychosocial stress, access to health care and health care usage. Some of these pre- and postmigration environmental factors may interact with genetic (epigenetics) and microbial factors, which further influence their CVD risk. The limited number of prospective cohorts and clinical trials in migrant populations remains an important culprit for better understanding pathophysiological mechanism driving health differences and for developing ethnic-specific CVD risk prediction and care. Only by improved understanding of the complex interaction among human biology, migration-related factors, and sociocultural determinants of health influencing CVD risk will we be able to mitigate these differences and truly make inclusive personalized treatment possible.

Evaluation of Photobiomodulation on myocardial function of patients with advanced ischemic cardiomyopathy, A case series

BackgroundHeart failure is a growing cardiovascular disease burden with high mortality rates, primarily attributed to myocardial ischemia. Previous studies have shown promising effects of Photobiomodulation in heart failure treatment. In this study, we aimed to investigate the effect of Photobiomodulation on myocardial function of patients with advanced ischemic heart failure. MethodA non-randomized case series study involving 10 advanced heart failure patients was conducted. Patients received 15 sessions of transcutaneous and intravenous Photobiomodulation therapy using low-level red (658 nm) and infrared lasers (810 nm). All participants were evaluated by six-minute walk tests, dyspnea function classes, and echocardiography. 3 months after the sessions, the mentioned tests were reevaluated ResultThe study included ten cardiomyopathic patients, 90 % male and the mean age was 63.20±6.01 years. The six-minute walk test change and shortness of breath function class change has 0.852 (p-value=0.006) correlation and the correlation between the Six-minute walk test change and the Systolic ejection fraction rate change, was 0.73 (p-value=0.025). ConclusionBased on the results of the study, it can be concluded that interventions in cardiomyopathic patients have shown promising improvements in certain cardiac function parameters. Specifically, the significant enhancement in the six-minute walk test post-intervention (p = 0.013) suggests a positive impact on functional capacity. Although the increase in systolic ejection fraction rate was not statistically significant (p = 0.197), the correlations identified provide valuable insights into the interplay between variables such as shortness of breath function class and the six-minute walk test. These findings underscore the complexity of managing cardiomyopathy and highlight the importance of further research to elucidate the relationships between different clinical parameters and patient outcomes in this population.

Cardiovascular Disease Burden Attributable to High Sodium Intake in China: A Longitudinal Study from 1990 to 2019.

Overconsumption of sodium has been identified as a key driving factor for diet-related cardiovascular diseases (CVDs). China, being a country bearing a hefty burden of CVD, has a large population with diverse cultural traditions and ethnic beliefs, which complicates the patterns of dietary sodium intake, necessitating a systematic investigation into the profile of the high sodium intake (HSI)-related burden of CVD within its subregions. This study aims to estimate the evolving patterns of HSI-induced CVD burden across China from 1990 to 2019. The methodology used in the Global Burden of Disease Study was followed to assess deaths and disability-adjusted life years (DALYs) by age, sex, region, and socio-demographic index (SDI). The estimated annual percentage change (EAPC) was calculated to quantify the secular changes in the age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR). In 2019, 0.79 million deaths and 1.93 million DALYs of CVD were attributed to HSI, an increase of 53.91% and 39.39% since 1990, respectively. Nevertheless, a downward trend in ASMR (EAPC: -1.45, 95% CI: -1.55, -1.35) and ASDR (EAPC: -1.61, 95% CI: -1.68, -1.53) was detected over time. ASMR and ASDR were higher for males, individuals aged ≥60 years, and regions with low-middle SDI. A markedly negative association between the EAPC in both ASMR and ASDR and the SDI was found in 2019 (ρ = -0.659, p < 0.001 and ρ = -0.558, p < 0.001, respectively). The HSI-induced CVD burden is gender-, age-, and socioeconomic-dependent. Integrated and targeted strategies for CVD prevention are anticipated in the future throughout China.

Cardiovascular Health and Disease in the Pakistani American Population.

This narrative review seeks to elucidate clinical and social factors influencing cardiovascular health, explore the challenges and potential solutions for enhancing cardiovascular health, and identify areas where further research is needed to better understand cardiovascular issues in native and American Pakistani populations. The prevalence of cardiometabolic disease is high not only in Pakistan but also among its global diaspora. This situation is further complicated by the inadequacy of current cardiovascular risk assessment tools, which often fall short of accurately gauging the risk among Pakistani individuals, underscoring the urgent need for more tailored and effective assessment methodologies. Moreover, social determinants play a crucial role in shaping cardiovascular health. The burden of cardiovascular disease and upstream risk factors is high among American Pakistani individuals. Future research is needed to better understand the heightened risk of cardiovascular disease among Pakistani individuals.

Environmental Impacts on Cardiovascular Health and Biology: An Overview.

Environmental stressors associated with human activities (eg, air and noise pollution, light disturbance at night) and climate change (eg, heat, wildfires, extreme weather events) are increasingly recognized as contributing to cardiovascular morbidity and mortality. These harmful exposures have been shown to elicit changes in stress responses, circadian rhythms, immune cell activation, and oxidative stress, as well as traditional cardiovascular risk factors (eg, hypertension, diabetes, obesity) that promote cardiovascular diseases. In this overview, we summarize evidence from human and animal studies of the impacts of environmental exposures and climate change on cardiovascular health. In addition, we discuss strategies to reduce the impact of environmental risk factors on current and future cardiovascular disease burden, including urban planning, personal monitoring, and mitigation measures.

Atherosclerotic cardiovascular disease landscape in Singapore.

Cardiovascular disease (CVD) is the leading cause of death worldwide, accounting for over one-third of all deaths in Singapore. An analysis of age-standardized mortality rates (ASMR) for CVD in Singapore revealed a deceleration in the initial rapid decline in ASMR. A decrease in smoking prevalence may have contributed to the initial rapid decline in ASMR. Furthermore, other major risk factors, such as diabetes mellitus, hypertension, elevated low-density lipoprotein levels, and obesity, are steadily rising. Singapore's CVD economic burden is estimated to be 8.1 billion USD (11.5 billion SGD). The burden of CVD can only be reduced using individual and population-based approaches. Prevention programs must also be developed based on an understanding of risk trends. Therefore, this article attempts to capture the burden of CVD, trends in risk factor control, preventive care, disparities, and current unmet needs, particularly in atherosclerotic cardiovascular disease management in Singapore.

Long-term Effects of Kidney Transplantation Compared With Dialysis on Intima-media Thickness in Children-Results From the 4C-T Study.

Children requiring kidney replacement therapy experience high burden of cardiovascular (CV) disease leading to increased mortality. Intima-media thickness (IMT) indicating atherosclerosis is a validated surrogate marker for future CV events. We investigated the effect of different treatment modalities (dialysis, preemptive kidney transplantation (KTx), late KTx after dialysis) on IMT by multivariable linear mixed-effect modeling. Patients were enrolled in a prospective cohort study. A total of 261 analyzed children had a mean follow-up of 3 y. Children after preemptive and late KTx had lower levels of IMT when compared with dialysis. Using an interaction term, a significant progression of IMT over time was seen during dialysis (β = 0.0053 mm/y, P = 0.004). IMT before the start of therapy was the most influential determinant in all models. Low IMT was associated with maintenance steroid treatment after preemptive KTx. High IMT on dialysis was associated with higher systolic blood pressure, lower body mass index, lower serum albumin, and lower bicarbonate. IMT remained rather stable in children several years after KTx. In contrast, children on dialysis had higher IMT values, which increased over time. In these children, blood pressure control, calorie and protein intake, and acid-base homeostasis seem important. Taken together, children might profit from early transplantation to limit accumulation of CV risk.

E012 Burden and risk factors for cardiovascular involvement in connective tissue disease

Abstract Background/Aims Connective tissue diseases (CTD) are associated with several cardiovascular manifestations. Cardiovascular diseases (CVD) are significant cause of morbidity and premature death. The pathogenesis of CVD in CTD patients is incompletely understood and likely multifactorial. Traditional risk factors for atherosclerosis are common among patients with CTD as well as metabolic syndrome. Furthermore, diabetes, dyslipidaemia, hypertension, and obesity may all be exacerbated by connective tissue disease itself or treatment with glucocorticoids. The aim of this study was to assess the burden of CVD and the risk factors for the development of cardiovascular disease in patients with CTD. Methods This was a retrospective study from a single centre. We reviewed clinical records of CTD patients as determined by treating rheumatologist. This CTD cohort included patients with systemic lupus erythematosus (SLE), myositis, systemic sclerosis, Sjogren’s syndrome, mixed and undifferentiated connective tissue diseases. Data on demographic, clinical, laboratory parameters, cardiac investigations, treatment and outcome were collected from electronic patient records. CVD and traditional risk factors were defined using standard criteria. Results A total of 298 patients with CTD were included in the analysis. Mean age of the cohort was 61±17.7 years and majority were females (n = 240, 80.5%). Of the 298 patients, 64 had CVD (21.5%). Most common CVD was ischaemic heart disease (17 patients) followed by hypertension (12), arrhythmia (9), pulmonary arterial hypertension (7), valvular diseases (5), pericardial disease (3), cardiomyopathy (3), myocarditis (2), thromboembolism (3), aortic dissection (2) and coronary spasm (1). Patient with CTD who had CVD were older (72.5±12.2 years) compared to CTD patients who did not develop CVD (non-CVD group, 57.7±17.6 years). The duration of CTD was shorter in patients with CVD (88.9±41.7 months), compared to 106±84.3 months in non-CVD group. The risk factors such as smoking, diabetes and dyslipidaemia was higher in the CVD group. Comparing CVD vs non-CVD patients respectively, systolic BP (147.1±23.0 vs 133.6±18.3mmHg), diastolic BP (83.2 ± 16.3 vs 78.2 ± 11.2mmHg) and serum uric acid (321.8±97.4 vs 292±83.9mg/dL) values were higher and statistically significant (p &amp;lt; 0.05) in CVD group. Patients with CVD had longer exposure to steroids (50%) compared to non-CVD patients (31.6%). They required high dose steroids (9.4% vs 5.6% in non-CVD patients). Current and previous DMARD use was also higher in patients who had CVD (51.6% vs 44.9%). Conclusion This study has demonstrated high burden of cardiovascular disease in CTD patients. Traditional risk factors were more prevalent in the CVD group. DMARD’s and steroid use was also higher in the CVD group. Screening for cardiovascular diseases and disease control in CTD patients is paramount for better outcomes. Further analysis will be carried out for risk factors and relevant outcomes.

Healthy rural hearts: The feasibility of a telehealth nutrition randomised controlled trial for rural people at risk of cardiovascular disease.

Improving dietary patterns using medical nutrition therapy delivered via telehealth could make an effective contribution to reducing cardiovascular disease burden in rural Australia. However, it is important that medical nutrition therapy programmes are developed in collaboration with rural stakeholders, to increase feasibility for the rural context and the likelihood of successful implementation. The aim of this study was to evaluate the preliminary feasibility outcomes of integration (implementation), practicality, acceptability, demand, and preliminary effectiveness at the 3-month timepoint of the Healthy Rural Hearts randomised control trial. Feasibility measures were collected from participants in the Healthy Rural Hearts medical nutrition therapy trial. Study participants were patients from eligible primary care practices who had been assessed by their general practitioner as being at moderate to high risk of developing cardiovascular disease in the next five years. The sample in this analysis includes those who had completed the first 3-months of the study. Feasibility outcomes were measured over the first 3-months of the trial intervention. A process evaluation survey was used to collect measures relating to intervention implementation, practicality, acceptability, and demand. Completion rates of the Australian Eating Survey Heart version, Personalised Nutrition Questionnaire, pathology tests and telehealth medical nutrition therapy consultations delivered by Accredited Practising Dietitians were also used to measure intervention practicality. Preliminary effectiveness was evaluated by comparing the intervention group's dietary change, measured using Australian Eating Survey Heart with data from the control group. A total of 105 participants (75 intervention, 30 control participants) were eligible for inclusion in analysis. Attendance rates at the first 3-months of dietitian consultations ranged from 94.7% to 89.3% between the first and 3-month consultations, and most participants were able to complete the Australian Eating Survey Heart and Personalised Nutrition Questionnaire prior to their initial consultation [Australian Eating Survey Heart (n = 57, 76%) and Personalised Nutrition Questionnaire (n = 61, 81.3%)] and the Australian Eating Survey Heart prior to their 3-month consultation (n = 52, 69.3%). Of the participants who completed a pathology test at the 3-month time-point (n = 54, 72%), less than half were able to do so prior to their dietitian consultation (n = 35, 46.7%). Of the 75 intervention participants, 28 (37.3%) completed the process evaluation survey. Intervention participants ranked acceptability of the Healthy Rural Hearts intervention highly (mean rank out of 10 = 9.5, SD 1.9), but provided mixed responses on whether they would access the intervention outside of the study (mean rank out of 10 = 6.0, SD 3.5). There were statistically significant increases in percentage total energy intake derived from nutrient-dense core foods compared to the control group (p ≤ 0.05). The positive findings related to acceptability and implementation outcomes suggest that the Healthy Rural Hearts intervention was acceptable, practical, and able to be implemented within this population living in rural NSW. This, combined with the small to medium effect size in the proportion of total energy derived from nutrient-dense core foods compared to the control group indicates that long-term intervention effectiveness on other cardiovascular disease outcomes is important to evaluate in the future.

The Association between Circulating Cytokines and Body Composition in Frail Patients with Cardiovascular Disease.

The burden of cardiovascular disease and the percentage of frail patients in the aging population will increase. This study aims to assess the circulating levels of several cytokines in frail patients. This is an ancillary analysis of the FRAPICA trial. The ratio of men/women changed from robust through frail groups from 3:1 to 1:2. The groups are comparable in terms of age and body measurements analysis (weight, height, and BMI), yet the frail patients have significantly reduced fat-free mass, and more often have been diagnosed with diabetes. Frail patients have higher fibroblast growth factor basic (FGF basic) and follistatin levels (borderline significance). In multiple linear regression modeling of fat-free mass, we identified FGF basic, osteopontin, stem cell factor, soluble suppression of tumorigenicity 2, soluble epidermal growth factor receptor, soluble human epidermal growth factor receptor 2, follistatin, prolactin, soluble interleukin 6 receptor alfa, platelet endothelial cell adhesion molecule 1, soluble vascular endothelial cell growth factor receptor 1, leptin, soluble angiopoietin/tyrosine kinase 2, and granulocyte colony-stimulating factor. We have identified a few cytokines that correlate with fat-free mass, a hallmark of frailty. They comprise the kinins implicated in bone and muscle metabolism, fibrosis, vascular wall function, inflammation, endocrine function, or regulation of bone marrow integrity.

Metabolic risks remain a serious threat to cardiovascular disease: findings from the Global Burden of Disease Study 2019.

Metabolic factors are major and controllable risk factors for cardiovascular diseases (CVD), and few studies have described this burden. We aim to assess it from 1990 to 2019 and predict the trends through 2034. Global Burden of Disease (GBD) provides data on sex, age, and socio-demographic index (SDI) levels. Numbers, age-standardized death rates (ASDR) and estimated annual percentage change (EAPC) were used. Future trends were estimated by NORDPRED model. The deaths cases of metabolic-related CVD increased from 8.61 million (95% UI: 7.91-9.29) to 13.71 million (95% UI: 12.24-14.94) globally. The ASDR continued to decline globally (EAPC = -1.36). The burden was heavier in male and middle-aged people and elderly people. CVD-related ASDR caused by high systolic blood pressure (SBP) had a downward trend globally (EAPC = -1.45), while trends of high body mass index (BMI) (EAPC = 1.29, 1.97, 0.92) and fasting plasma glucose (FPG) (EAPC = 0.95, 1.08, 0.46) were increasing in the middle, low-middle, and low SDI regions, respectively. Compared to 2015-2019, cumulative deaths will increase by 27.85% from 2030 to 2034, while ASDR will decrease 10.47%. The metabolic-related CVD burden remained high globally and deaths will continue to rise in the future. Men, middle-aged and elderly people were focus of concern. High SBP was globally well-managed over the past 30years, but the CVD burden due to high BMI and FPG remained high. Exceptional initiatives are needed to regarding interventions targeting high BMI and FPG in middle and lower SDI regions.
