The associations between circulating PUFA and cardiovascular risk factors and events in healthy Asian populations have been less examined robustly compared with Western populations. This systematic review aimed to summarise current evidence on the associations between n-3 and n-6 PUFA biomarkers and cardiovascular risk factors and events in healthy Asian populations. Four databases were searched for observational studies from 2010 until 2024. Twenty-three studies were eligible, which covered six Asian countries and included events (n 7), traditional risk factors such as blood pressure and lipids (n 4), physical signs such as arterial stiffness (n 4), non-traditional lipid markers (n 1), markers of inflammation (n 4), markers of thrombosis (n 2) and non-invasive imaging-based markers (n 5). Biological sample types included plasma (n 6), serum (n 14) and erythrocyte (n 3). Higher circulating total n-3 PUFA appeared to be associated with lower hypertension risk and specifically EPA and DHA to be associated with lower myocardial infarction risk, reduction in TAG and inflammation. Higher circulating linoleic acid was associated with improved lipid profiles and lower inflammation. Limited evidence led to inconclusive associations between circulating n-6 PUFA biomarkers and CVD events and blood pressure. No consistent associations with arterial stiffness, obesity, thrombosis and imaging-based biomarkers were observed for circulating PUFA biomarkers in Asian populations. Limited studies exist for each outcome; hence, results should be interpreted with caution. More high-quality and prospective studies in Asian populations are warranted. Several recommendations such as sample size justification and reporting of non-respondents rate are proposed for future studies.

Although the relationship between dyslipidaemia (DL) and coronary artery disease (CAD) or between trace minerals intake and CAD is well known separately, the exact nature of this relationship remains unknown. We hypothesize that the relationship between trace mineral intake and CAD may differ depending on whether or not the individual has DL. The present study analysed the relationships among trace mineral intake, DL, and CAD in middle-aged and older adults living in Shika town, Ishikawa prefecture, Japan. This study included 895 residents following the exclusion of those with genetic risk carriers for familial hypercholesterolemia. Trace mineral intake was evaluated using the brief-type self-administered diet history questionnaire. Interactions were observed between DL and CAD with zinc (p = 0.004), copper (p = 0.010), and manganese intake (p < 0.001) in a two-way analysis of covariance adjusted for covariates such as sex, age, body mass index, and current smokers and drinkers. Multiple logistic regression analysis showed that zinc (odds ratio (OR): 0.752; 95% confidence interval (CI): 0.606, 0.934; p = 0.010), copper (OR: 0.175; 95% CI: 0.042, 0.726; p = 0.016), and manganese (OR: 0.494; 95% CI: 0.291, 0.839; p = 0.009) were significant independent variables for CAD in the dyslipidaemic group. The present results suggest that DL with a low trace mineral intake is associated with CAD. Further longitudinal studies are required to confirm this relationship.

Deubiquitinases are a group of proteins that identify and digest monoubiquitin chains or polyubiquitin chains attached to substrate proteins, preventing the substrate protein from being degraded by the ubiquitin-proteasome system. Deubiquitinases regulate cellular autophagy, metabolism and oxidative stress by acting on different substrate proteins. Recent studies have revealed that deubiquitinases act as a critical regulator in various cardiac diseases, and control the onset and progression of cardiac disease through a board range of mechanism. This review summarizes the function of different deubiquitinases in cardiac disease, including cardiac hypertrophy, myocardial infarction and diabetes mellitus-related cardiac disease. Besides, this review briefly recapitulates the role of deubiquitinases modulators in cardiac disease, providing the potential therapeutic targets in the future.

Although Kawasaki disease is often self-limiting, significant cardiovascular sequelae may occur in the acute or late stage. The most common late complication is persistent coronary artery aneurysm, which can lead to myocardial ischaemia and even myocardial infarction. We report a case of coronary artery bypass grafting in a 16-year-old boy with a history of undiagnosed Kawasaki disease. Increased awareness of Kawasaki disease, especially among children between the ages of 6 months and 5 years, can increase early treatment and prevent serious complications that may occur in the future.

Over the years, numerous observational studies have substantiated that various dietary choices have opposing effects on CVD. However, the causal effect has not yet been established. Thus, we conducted a Mendelian randomisation (MR) analysis to reveal the causal impact of dietary habits on CVD. Genetic variants strongly associated with 20 dietary habits were selected from publicly available genome-wide association studies conducted on the UK Biobank cohort (n 449 210). Summary-level data on CVD were obtained from different consortia (n 159 836–977 323). The inverse-variance weighted method (IVW) was the primary outcome, while MR-Egger, weighted median and MR Pleiotropy RESidual Sum and Outlier were used to assess heterogeneity and pleiotropy. We found compelling evidence of a protective causal effect of genetic predisposition towards cheese consumption on myocardial infarction (IVW OR = 0·67; 95 % CI = 0·544, 0·826; P = 1·784 × 10−4) and heart failure (IVW OR = 0·646; 95 % CI = 0·513, 0·814; P = 2·135 × 10−4). Poultry intake was found to be a detrimental factor for hypertension (IVW OR = 4·306; 95 % CI = 2·158, 8·589; P = 3·416 × 10−5), while dried fruit intake was protective against hypertension (IVW OR = 0·473; 95 % CI = 0·348, 0·642; P = 1·683 × 10−6). Importantly, no evidence of pleiotropy was detected. MR estimates provide robust evidence for a causal relationship between genetic predisposition to 20 dietary habits and CVD risk, suggesting that well-planned diets may help prevent and reduce the risk of CVD.

Type 2 diabetes (T2D) and CVD are major causes of mortality and chronic morbidity. Whilst mortality from CVD has decreased they remain the largest cause of death in Europe and the prevalence of T2D is increasing rapidly. A consistent component of public health advice is to reduce intake of SFA to reduce CVD in particular, which implies limiting dairy food consumption. The prospective studies and randomised controlled trials included in this review show that for dairy foods at least, SFA are not consistently associated with CVD or T2D risk. For CVD the association with dairy foods is generally neutral despite dairy foods being the major source of SFA in many diets. This creates considerable doubt, at least for dairy foods, concerning the validity of the traditional diet-heart hypothesis which positively relates SFA intake to increased serum LDL-cholesterol and subsequent increased CVD. There is now emerging evidence to explain this which is highly relevant to dairy foods. These include the potentially counterbalancing effect of SFA-stimulated HDL-cholesterol and specific food matrix factors. In addition, SFA are associated with the less atherogenic large buoyant LDL particles and possible counterbalancing hypotensive effects of dairy proteins. Overall, dairy foods have either a neutral or beneficial association with CVD and T2D. Beneficial associations are seen for blood pressure and the reduced T2D risk linked to yoghurt consumption, a subject that needs urgent attention given the sharp rise in T2D prevalence in many countries.

Kawasaki disease is usually self-limited, but it can lead to aneurysm, stenosis, thrombosis, and myocardial infarction in the coronary arteries. The most important complication of Kawasaki disease is coronary artery aneurysm. Coronary artery aneurysm or ectasia may be seen in 15–25% of patients who do not receive treatment. It develops in 5% of children who receive intravenous immunoglobulin at the appropriate time. Acute myocardial infarction is the most important cause of morbidity and mortality in Kawasaki patients with giant aneurysms. We present a 10-year-old girl who had a history of giant aneurysm in the coronary arteries and underwent percutaneous coronary intervention due to anterior myocardial infarction.

The first investigation of dietary intake in the Mediterranean region was undertaken at the initiative of the government of Greece in 1948. Plant foods (cereals, pulses, nuts, potatoes, vegetables and fruits) accounted for 61 % of total energy intake (TEI), animal foods (meat, eggs, fish and dairy products) for 7 % of TEI and olive oil was the main oil used. In 1950s, Ancel Keys undertook studies in USA, Italy, Spain, England, Japan, Australia and Canada leading him to hypothesise that a link could exist between diet, plasma cholesterol and CHD. Between 1958 and 1964, Keys and co-workers carried out the Seven Countries Study, which enrolled men aged 40–59 years in one of sixteen cohorts from seven countries (Finland, Greece, Italy, Yugoslavia, Japan, USA and Italy). After 15-, 25- and 50-year follow-up, a strong positive relation was observed between saturated fat intake and CHD mortality, and a negative one with Mediterranean Dietary Index. In 1975, Keys and his wife published a book entitled: ‘How to eat well and stay well. The Mediterranean way’, which popularised Mediterranean Diet (MedDiet). After 45-year follow-up, longevity without CHD death was 12·9 years higher in Crete than in Finland. Protecting effect of MedDiet towards CHD incidence and risk is now confirmed by Prevencion con Dieta Mediterranea study and by cohorts’ studies gathered in several recent meta-analyses. MedDiet is sustainable and recognised by UNESCO as an intangible cultural heritage, which is the most beautiful homage that can be paid to Ancel Keys and all his co-workers.

This series describes three adolescent females who presented with chest pain and ventricular dysfunction related to acute coronary ischemia secondary to Takayasu’s arteritis with varied courses of disease progression leading to a diverse range of therapies including cardiac transplantation. While Takayasu’s arteritis is rare in childhood, it should be strongly considered in any adolescent female presenting with systemic inflammation and chest pain consistent with myocardial infarction. A high index of suspicion can lead to early detection and aggressive management of the underlying vasculitis reducing associated morbidity and mortality. The purpose of this report is to describe the challenges in the clinical diagnosis and management of Takayasu’s arteritis with myocardial infarction. We also seek to enhance awareness about unique presentations of Takayasu’s arteritis within the paediatric community.

Intake of vegetables is recommended for the prevention of myocardial infarction (MI). However, vegetables make up a heterogeneous group, and subgroups of vegetables may be differentially associated with MI. The aim of this study was to examine replacement of potatoes with other vegetables or subgroups of other vegetables and the risk of MI. Substitutions between subgroups of other vegetables and risk of MI were also investigated. We followed 29 142 women and 26 029 men aged 50–64 years in the Danish Diet, Cancer and Health cohort. Diet was assessed at baseline by using a detailed validated FFQ. Hazard ratios (HR) with 95 % CI for the incidence of MI were calculated using Cox proportional hazards regression. During 13·6 years of follow-up, 656 female and 1694 male cases were identified. Among women, the adjusted HR for MI was 1·02 (95 % CI 0·93, 1·13) per 500 g/week replacement of potatoes with other vegetables. For vegetable subgroups, the HR was 0·93 (95 % CI 0·77, 1·13) for replacement of potatoes with fruiting vegetables and 0·91 (95 % CI 0·77, 1·07) for replacement of potatoes with other root vegetables. A higher intake of cabbage replacing other vegetable subgroups was associated with a statistically non-significant higher risk of MI. A similar pattern of associations was found when intake was expressed in kcal/week. Among men, the pattern of associations was overall found to be similar to that for women. This study supports food-based dietary guidelines recommending to consume a variety of vegetables from all subgroups.

Several countries have issued dietary recommendations about total and specific fatty acid (FA) intake for the prevention of CHD. For many years until today, controversies have existed especially about the deleterious effect or not of SFA, and the protective effect or not of n-3 PUFA, so that some authors have criticised these recommendations. There are many reasons for these controversies, including the different conclusions of prospective cohort studies compared with randomised clinical trials (RCT), and the contradictory conclusions of meta-analyses depending on the quality, number and type of studies included. The interrelationships between different FA in the diet make it difficult to analyse the specific effect of a particular class of FA on CHD. Furthermore, based on clinical practice and effectiveness of population-based prevention, it is very difficult at the individual level to assess in personal dietary intake the actual percentage and/or amount of SFA contained in each meal or consumed daily/weekly. In this critical narrative review, we try to answer the question of whether it would not be more relevant, in 2020, to promote dietary patterns, rather than FA intake recommendations. We critically analyse past and recent data on the association of FA with CHD, then propose that the Mediterranean diet and Japanese diet should be revitalised for Westerners and Asian populations, respectively. This does not exclude the usefulness of continuing research about effects of FA towards CHD, and accepting that what seems true today might be revised, at least partially tomorrow.
