Sodium intake shows a positive correlation with blood pressure, resulting in an increased risk for cardiovascular diseases (CVD). Salt reduction is a key step toward the WHO's goal of 25% reduction in mortality from non‐communicable diseases (NCDs) by 2025. This study aims to assess the current condition and temporal changes of the global CVD burden due to high sodium intake (HSI). We extracted data from the Global Burden of Disease (GBD) study 2019. The numbers and age‐standardized rates of mortality and disability‐adjusted life‐years (DALYs), stratified by location, sex, and socio‐demographic Index (SDI), were used to assess the high sodium intake attributable CVD burden from 1990 to 2019. The relationship between the DALYs rates and related factors was evaluated by stepwise multiple linear regression analysis. Globally, in 2019, the deaths and DALYs of HSI‐related CVD were 1.72 million and 40.54 million, respectively, increasing by 41.08% and 33.06% from 1990. Meanwhile, the corresponding mortality and DALYs rates dropped by 35.1% and 35.2%, respectively. The high‐middle and middle SDI quintiles bore almost two‐thirds of CVD burden caused by HSI. And the leading cause of HSI attributable CVD burden was ischemic heart disease. Universal health coverage (UHC) was associated with the DALYs rates after adjustment. From 1990 to 2019, the global CVD burden attributable to HSI has declined with spatiotemporal and sexual heterogeneity. However, it remains a major public health challenge because of the increasing absolute numbers. Improving UHC serves as an effective strategy to reduce the HSI‐related CVD burden.

Purpose of Review Apolipoprotein C-III (ApoC-III) is a widely known player in triglyceride metabolism, and it has been recently recognized as a polyhedric factor which may regulate several pathways beyond lipid metabolism by influencing cardiovascular, metabolic, and neurological disease risk. This review summarizes the different functions of ApoC-III and underlines the recent findings related to its multifaceted pathophysiological role. Recent Findings The role of ApoC-III has been implicated in HDL metabolism and in the development of atherosclerosis, inflammation, and ER stress in endothelial cells. ApoC-III has been recently considered an important player in insulin resistance mechanisms, lipodystrophy, diabetic dyslipidemia, and postprandial hypertriglyceridemia (PPT). The emerging evidence of the involvement of ApoC-III in the in the pathogenesis of Alzheimer’s disease open the way to further study if modification of ApoC-III level slows disease progression. Furthermore, ApoC-III is clearly linked to cardiovascular disease (CVD) risk, and progression of coronary artery disease (CAD) as well as the calcification of aortic valve and recent clinical trials has pointed out the inhibition of ApoC-III as a promising approach to manage hypertriglyceridemia and prevent CVD. Summary Several evidences highlight the role of ApoC-III not only in triglyceride metabolism but also in several cardio-metabolic pathways. Results from recent clinical trials underline that the inhibition of ApoC-III is a promising therapeutical strategy for the management of severe hypertriglyceridemia and in CVD prevention.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Health research is crucial to managing disease burden. Previous work has highlighted marked discrepancies in research output and disease burden between high-income countries (HICs) and low- and lower-middle-income countries (LI-LMICs) and there is little data to understand whether this gap has bridged in recent years. We conducted a global, country level bibliometric analysis of CVD publications with respect to trends in disease burden and county development indicators. A search filter with a precision and recall of 0.92 and 0.91 respectively was developed to extract cardiovascular publications from the Web of Science (WOS) for the years 2008-2017. Data for disease burden and country development indicators were extracted from the Global Burden of Disease and the World Bank database respectively. Our search revealed 847,708 CVD publications for the period 2008-17, with a 43.4% increase over the decade. HICs contributed 81.1% of the global CVD research output and accounted for 8.1% and 8.5% of global CVD DALY losses deaths respectively. LI-LMICs contributed 2.8% of the total output and accounted for 59.5% and 57.1% global CVD DALY losses and death rates. A glaring disparity in research output and disease burden persists. While LI-LMICs contribute to the majority of DALYs and mortality from CVD globally, their contribution to research output remains the lowest. These data call on national health budgets and international funding support to allocate funds to strengthen research capacity and translational research to impact CVD burden in LI-LMICs.

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.

Purpose of Review Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. CVDs contribute to a large health and economic burden on a global scale. We aim to describe the current landscape of global cardiovascular research, highlight significant findings, and identify potential opportunities for further studies. Recent Findings There has been remarkable research output regarding cardiovascular health in recent decades. Large-scale collaborative studies have made impactful strides in identifying modifiable risk factors and forming evidence-based guidelines to facilitate improved cardiovascular care and outcomes. However, there are significant CVD disparities between high- and low- income countries which require interventions to mitigate these inequalities. Summary Encouraging collaborative partnerships, strengthening research capacity in low-resource settings, and promoting equity in research are fundamental strategic approaches to help improve global cardiovascular research.

Background Hypertension was once considered rare in sub-Saharan Africa (SSA), but currently it has become a widespread problem with immense socioeconomic importance. The purpose of this review is to summarise new information on hypertension in SSA that has been published since the last major review in 2008. Methods and results A literature search was performed in Pubmed, Embase, WHO Global Cardiovascular Infobase, African Journal On-Line, and African Index Medicus using the following search criteria: hypertension, high blood pressure, and Africa/SSA. Epidemiological surveys that used the WHO STEPS approach or similar methods were also included. The overall prevalence of hypertension in SSA was estimated at 16.2% (95% CI 14.2% to 20.3%) with an estimated number of hypertensive individuals to be 74.7 million. The prevalence of hypertension varies widely from country to country. It is projected that the number of affected individuals will increase by 68% (125.5 million) by 2025. Mass migration of rural Africans to urban areas and rapid changes in lifestyle and risk factors account for the rising prevalence of hypertension. Conclusions Proactive public health interventions at a population level need to be introduced to control the growing hypertension epidemic, and there needs to be a major improvement in access to hypertensive care for the individual. There is an important need for better epidemiological data and hypertension related outcome trials in SSA.

Congenital heart anomalies (CHAs) are a leading cause of premature childhood mortality and contribute substantially to years of life lost (YLL). Despite overall improvements in child survival in Southeast Asia, progress in reducing CHA-attributed mortality has been uneven. Examining how trends in CHA-related YLL align with socioeconomic development is critical for informing targeted health system investments. This study assesses trends and projections of CHA-attributed premature mortality in ASEAN countries from 2000 to 2030 in relation to development levels. Data from the Global Burden of Disease Study 2021 were used to extract CHA-attributed YLL rates, including all-age and age-stratified estimates (<5, 5-9, and 10-19 years), alongside Socio-demographic Index (SDI) values from 2000 to 2021. Estimated Annual Percentage Change (EAPC) for YLL and SDI was calculated using log-linear regression, and an efficiency ratio quantified YLL reduction per unit SDI gain. Forecasts up to 2030 were generated using ARIMA and ARIMAX models applied to the natural logarithm-transformed outcome values, with SDI trajectories stratified by recent growth patterns. From 2000 to 2021, all ASEAN countries showed declining CHA-attributed YLL. Singapore achieved the steepest decline (from 104.27 to 26.09 per 100,000) and highest efficiency relative to SDI gains. Children under five consistently bore the greatest burden, with 2021 YLLs ranging from 319 per 100,000 in Singapore to 7,435 per 100,000 in Lao PDR, a more than 23-fold disparity. Under SDI-adjusted projections to 2030, Cambodia, Lao PDR, Myanmar, and Timor Leste were projected to achieve moderate reductions of approximately 16-29% compared with 2021, although their absolute YLL levels remained high (YLLs > 600 per 100,000). The estimated trends in Singapore and Brunei Darussalam exceeded those expected under the SDI-adjusted projections, with projected YLLs of 17.35 and 131.67 per 100,000 population, respectively. CHA-attributed premature mortality is largely preventable but not assured by development alone. Greater YLL reductions occur when investment in pediatric cardiac care keep pace with socioeconomic progress, highlighting the need for targeted interventions in countries with rising SDI but limited mortality reduction.

ObjectiveTo describe the current situation and trends in mortality due to cardiovascular disease (CVD) in the Americas and explore their association with economic indicators.Design and SettingThis time series study analysed mortality data from 21 countries in the region of the Americas from 2000 to the latest available year.Main Outcomes MeasuresAge-adjusted death rates, annual variation in death rates. Regression analysis was used to estimate the annual variation and the association between age-adjusted rates and country income.ResultsCurrently, CVD comprised 33.7% of all deaths in the Americas. Rates were higher in Guyana (292/100 000), Trinidad and Tobago (289/100 000) and Venezuela (246/100 000), and lower in Canada (108/100 000), Puerto Rico (121/100 000) and Chile (125/100 000). Male rates were higher than female rates in all countries. The trend analysis showed that CVD death rates in the Americas declined −19% overall (−20% among women and −18% among men). Most countries had a significant annual decline, except Guatemala, Guyana, Suriname, Paraguay and Panama. The largest annual declines were observed in Canada (−4.8%), the USA (−3.9%) and Puerto Rico (−3.6%). Minor declines were in Mexico (−0.8%) and Cuba (−1.1%). Compared with high-income countries the difference between the median of death rates in lower middle-income countries was 56.7% higher and between upper middle-income countries was 20.6% higher.ConclusionsCVD death rates have been decreasing in most countries in the Americas. Considerable disparities still remain in the current rates and trends.

Objectives: We previously found large variations in general practitioner (GP) hypertension treatment probability in oldest-old (>80 years) between countries. We wanted to explore whether differences in country-specific cardiovascular disease (CVD) burden and life expectancy could explain the differences. Design: This is a survey study using case-vignettes of oldest-old patients with different comorbidities and blood pressure levels. An ecological multilevel model analysis was performed. Setting: GP respondents from European General Practice Research Network (EGPRN) countries, Brazil and New Zeeland. Subjects: This study included 2543 GPs from 29 countries. Main outcome measures: GP treatment probability to start or not start antihypertensive treatment based on responses to case-vignettes; either low (<50% started treatment) or high (≥50% started treatment). CVD burden is defined as ratio of disability-adjusted life years (DALYs) lost due to ischemic heart disease and/or stroke and total DALYs lost per country; life expectancy at age 60 and prevalence of oldest-old per country. Results: Of 1947 GPs (76%) responding to all vignettes, 787 (40%) scored high treatment probability and 1160 (60%) scored low. GPs in high CVD burden countries had higher odds of treatment probability (OR 3.70; 95% confidence interval (CI) 3.00-4.57); in countries with low life expectancy at 60, CVD was associated with high treatment probability (OR 2.18, 95% CI 1.12-4.25); but not in countries with high life expectancy (OR 1.06, 95% CI 0.56-1.98). Conclusions: GPs' choice to treat/not treat hypertension in oldest-old was explained by differences in country-specific health characteristics. GPs in countries with high CVD burden and low life expectancy at age 60 were most likely to treat hypertension in oldest-old. Key Points  * General practitioners (GPs) are in a clinical dilemma when deciding whether (or not) to treat hypertension in the oldest-old (>80 years of age).  * In this study including 1947 GPs from 29 countries, we found that a high country-specific cardiovascular disease (CVD) burden (i.e. myocardial infarction and/or stroke) was associated with a higher GP treatment probability in patients aged >80 years.  * However, the association was modified by country-specific life expectancy at age 60. While there was a positive association for GPs in countries with a low life expectancy at age 60, there was no association in countries with a high life expectancy at age 60.  * These findings help explaining some of the large variation seen in the decision as to whether or not to treat hypertension in the oldest-old.

Heart failure in sub-Saharan Africans is mainly due to non-ischaemic causes, such as hypertension, rheumatic heart disease, cardiomyopathy and pericarditis. The two endemic diseases that are major contributors to the clinical syndrome of heart failure in Africa are cardiomyopathy and pericarditis. The major forms of endemic cardiomyopathy are idiopathic dilated cardiomyopathy, peripartum cardiomyopathy and endomyocardial fibrosis. Endomyocardial fibrosis, which affects children, has the worst prognosis. Other cardiomyopathies have similar epidemiological characteristics to those of other populations in the world. HIV infection is associated with occurrence of HIV-associated cardiomyopathy in patients with advanced immunosuppression, and the rise in the incidence of tuberculous pericarditis. HIV-associated tuberculous pericarditis is characterised by larger pericardial effusion, a greater frequency of myopericarditis, and a higher mortality than in people without AIDS. Population-based studies on the epidemiology of heart failure, cardiomyopathy and pericarditis in Africans, and studies of new interventions to reduce mortality, particularly in endomyocardial fibrosis and tuberculous pericarditis, are needed.
