The impact of low ambient temperature on cardiovascular health

Extreme weather events and climate change have witnessed a substantial increase in recent years,leading to heightened concerns.The rise in abnormal ambient temperatures,both in intensity and frequency,directly and indirectly impacts cardiovascular health.While the impact of high ambient temperatures on cardiovascular response is a common concern in the context of global warming,the significance of low temperatures cannot be overlooked.The challenges posed by low temperatures contribute to increased cardiovascular morbidity and mortality,posing a significant threat to global public health.This review aims to provide an overview of the relationship between low ambient temperature and cardiovascular health,encompassing the burden of cardiovascular outcomes and underlying mechanisms.Additionally,the review explores strategies for cold adaptation and cardioprotection.We posit that to optimize cold adaptation strategies,future research should delve deeper into the underlying mechanisms of cardiovascular health in response to low ambient temperature exposure.

Ideal Cardiovascular Health Metrics and Coronary Artery Calcification in Northern Chinese Population:A Cross-sectional Study

Objective Coronary artery calcification（CAC） is a well-established risk predictor of coronary heart disease events and is recognized as an indicator of subclinical atherosclerosis.Methods A cross-sectional study consisting of 2999 participants aged ≥40 years from the Jidong community of Tangshan City,an industrial and modern city of China,was conducted between 2013 and 2014 to examine the association between the ideal cardiovascular health（CVH） metrics and CAC.The ideal CVH metrics were determined based on the definition of the American Heart Association（AHA）.The participants were then grouped into 4 categories according to the quartiles of their CVH metric scores as follows：first quartile（0-2）,second quartile（3）,third quartile（4）,and fourth quartile（5-7）.CAC was assessed by using high-pitch dual-source CT,and patients were identified based on thresholds of 0,10,100,or 400 Agatston units,as per common practice.Results The prevalence of subclinical atherosclerosis was 15.92%,13.85%,6.76%,and 1.93%,determined by using the CAC scores at thresholds of 0,10,100,and 400 Agatston units,respectively.Compared with the group in the first quartile,the other three CVH groups had a lower odds ratio of CAC 0 after adjusting for age,sex,income level,education level,and alcohol use in the logistic regression analysis.The odds ratios in these groups were 0.86 [95% confidence interval（CI）,0.63-1.17;P0.05],0.75（95% CI,0.55-1.02;P0.05）,and 0.49（95% CI,0.35-0.69;P0.05）,respectively.These associations of CAC with the CVH metrics were consistent when different CAC cutoff scores were used（0,10,100,or 400）.Conclusion The participants with more-ideal cardiovascular metrics had a lower prevalence of subclinical atherosclerosis determined according to CAC score.Maintaining an ideal cardiovascular health may be valuable in the prevention of atherosclerosis in the general population.

Illness perception and cardiovascular health behaviour among persons with ischemic heart disease in Indonesia

Objective:A study was conducted to explore the level of illness perception,the level of cardiovascular health behaviour and the relationship between illness perception and cardiovascular health behaviour among persons with ischemic heart disease(IHD)in a community setting.Method:The participants comprised 235 persons with IHD.The instruments used were as follows:1)Demographic Data and Health Information,2)The Brief Illness Perception Questionnaire(Brief IPQ),3)The Open-ended Questionnaire(OEQ),and 4)The Modified Cardiac Health Behaviour Scale(MCHBS).Findings from the OEQ are used to assess in-depth illness perception and to extend the information obtained from the Brief IPQ.The design of the study was descriptive correlational.The data were analysed using descriptive statistics to present the demographic data and health information.Inferential statistics was used to resolve the relationship between illness perception and cardiovascular health behaviour by using Pearson's Product Moment Correlation.Result:The mean score of illness perception was at a moderate level(M=43.65,SD=3.93),whereas the mean score of cardiovascular health behaviour was at a high level(M=80.29,SD=5.42).A significant positive relationship existed between illness perception and cardiovascular health behaviour among persons with IHD(r=0.38,P<0.01).Conclusion:Persons with higher illness perception showed a positive correlation with higher cardiovascular health behaviour at a significant level of 0.01.Results provided important information for nurses to develop an intervention program to promoting appropriate illness perception and cardiovascular health behaviour among persons with IHD.

Ideal Cardiovascular Health is Inversely Associated with Subclinical Atherosclerosis: A Prospective Analysis

Objective Ideal cardiovascular health(CVH) could predict a lower risk of developing cardiovascular diseases. This study was conducted to investigate the association between ideal CVH and subclinical atherosclerosis in a population cohort of Chinese adults aged ≥ 40 years. Methods This study was designed as a cross-sectional analysis of 8,395 participants who had complete data at baseline and a prospective analysis of 4,879 participants who had complete data at 4.3 years of follow-up. Ideal CVH metrics were defined according to the American Heart Association. Subclinical atherosclerosis was evaluated by plaques in carotid arteries, carotid intima-media thickness(CIMT), brachial-ankle pulse wave velocity(baPWV), and urinary albumin-to-creatinine ratio(UACR). Results Both the prevalence and incidence of atherosclerosis measures were found to be decreased with increasing numbers of ideal CVH metrics at baseline(all P values for trend < 0.01). The levels of CIMT and UACR at follow-up showed an inverse and significant association with the numbers of ideal CVH metrics at baseline(both P values for trend < 0.05) but a borderline significant association with baPWV(P for trend = 0.0505). Taking participants with 0-1 ideal metric as reference, we found that participants with 5-6 ideal metrics had significantly lower risks of developing carotid plaques(odds ratio, OR = 0.46; 95% confidence interval, CI 0.27-0.79), increased CIMT(OR = 0.60; 95% CI 0.42-0.84), and increased baPWV(OR = 0.57; 95% CI 0.34-0.97) after full adjustments. A significant interactive effect of age and CVH was detected on CIMT and baPWV progression(both P values for interaction < 0.05). Conclusion The numbers of ideal CVH metrics showed a significant and inverse association with the risk of developing subclinical atherosclerosis in middle-aged and elderly Chinese adults, whereas its dose-response effect was attenuated in individuals aged ≥ 60 years and partially weakened in male participants.

Ideal cardiovascular health and mortality:pooled results of three prospective cohorts in Chinese adults

Background: Evidence on the relations of the American Heart Association’s ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. Methods: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. Results: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. Conclusions: ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Decoding the nexus:branched-chain amino acids and their connection with sleep,circadian rhythms,and cardiometabolic health

The sleep-wake cycle stands as an integrative process essential for sustaining optimal brain function and,either directly or indirectly,overall body health,encompassing metabolic and cardiovascular well-being.Given the heightened metabolic activity of the brain,there exists a considerable demand for nutrients in comparison to other organs.Among these,the branched-chain amino acids,comprising leucine,isoleucine,and valine,display distinctive significance,from their contribution to protein structure to their involvement in overall metabolism,especially in cerebral processes.Among the first amino acids that are released into circulation post-food intake,branched-chain amino acids assume a pivotal role in the regulation of protein synthesis,modulating insulin secretion and the amino acid sensing pathway of target of rapamycin.Branched-chain amino acids are key players in influencing the brain's uptake of monoamine precursors,competing for a shared transporter.Beyond their involvement in protein synthesis,these amino acids contribute to the metabolic cycles ofγ-aminobutyric acid and glutamate,as well as energy metabolism.Notably,they impact GABAergic neurons and the excitation/inhibition balance.The rhythmicity of branchedchain amino acids in plasma concentrations,observed over a 24-hour cycle and conserved in rodent models,is under circadian clock control.The mechanisms underlying those rhythms and the physiological consequences of their disruption are not fully understood.Disturbed sleep,obesity,diabetes,and cardiovascular diseases can elevate branched-chain amino acid concentrations or modify their oscillatory dynamics.The mechanisms driving these effects are currently the focal point of ongoing research efforts,since normalizing branched-chain amino acid levels has the ability to alleviate the severity of these pathologies.In this context,the Drosophila model,though underutilized,holds promise in shedding new light on these mechanisms.Initial findings indicate its potential to introduce novel concepts,particularly in elucidating the intricate connections between the circadian clock,sleep/wake,and metabolism.Consequently,the use and transport of branched-chain amino acids emerge as critical components and orchestrators in the web of interactions across multiple organs throughout the sleep/wake cycle.They could represent one of the so far elusive mechanisms connecting sleep patterns to metabolic and cardiovascular health,paving the way for potential therapeutic interventions.

Dietary (poly)phenol intake is associated with cardiometabolic health parameters in adolescents

The protective role of(poly)phenols against metabolic disorders has been extensively studied in adults but not in adolescents.To assess associations of dietary(poly)phenols and their subclasses with cardiometabolic health parameters in adolescents.A cross-sectional study was conducted in 944 individuals aged 11–14 years enrolled in the SI!Program for Secondary Schools trial(NCT03504059).(Poly)phenol intake was assessed using semiquantitative food frequency questionnaires and the Phenol-Explorer database.The measured cardiometabolic parameters were waist circumference(WC)age-sex Z-score,blood pressure(BP)age-sex Z-score,blood glucose(BG),triglycerides(TG),and high-density lipoprotein cholesterol(HDL-c).Multilevel mixedeffect linear regression models were applied to examine the association between(poly)phenol quintiles and cardiometabolic health parameters.Compared to the lowest quintile,adolescents in the highest quintile of total(poly)phenol intake had lower WC Z-scores,mean arterial pressure Z-scores,and HDL-c after multivariable adjustment.The WC Z-scores and HDL-c were lower in the highest quintile of flavonoid intake compared to the lowest quintile.The highest quintile of phenolic acid intake was associated with a lower WC Z-score and TG levels,and the highest quintile of stilbene intake with lower BG and TG,and with higher HDL-c compared to the lowest quintile.A higher intake of(poly)phenols,especially flavonoids,phenolic acids,and stilbenes,was associated with better cardiometabolic parameters in adolescents.

Ideal cardiovascular health and incidence of atherosclerotic cardiovascular disease among Chinese adults:the China-PAR project

Existing evidence on the relationship between cardiovascular health(CVH) metrics and cardiovascular disease(CVD) was primarily derived from western populations. We aimed to evaluate the benefits of ideal CVH metrics on preventing incident atherosclerotic CVD(ASCVD) in Chinese population. This study was conducted among 93,987 adults from the China-PAR project(Prediction for ASCVD Risk in China) who were followed up until 2015. Cox proportional hazard regression models were used to estimate the hazard ratios(HRs) and their corresponding 95% confidence intervals(CIs) of CVH metrics for the risk of ASCVD, including coronary heart disease(CHD), stroke and ASCVD death. We further estimated the population-attributable risk percentage(PAR%) of these metrics in relation to each outcome. We observed gradient inverse associations between the number of ideal CVH metrics and ASCVD incidence. Compared with participants having ≤2 ideal CVH metrics, the multivariable-adjusted HRs(95% CIs) of ASCVD for those with 3, 4, 5, 6 and 7 ideal CVH metrics were 0.83(0.74–0.93), 0.66(0.59–0.74), 0.55(0.48–0.61), 0.44(0.38–0.50) and 0.24(0.18–0.31), respectively(P for trend <0.0001). Approximately 62.1% of total ASCVD, 38.7% of CHD, 66.4% of stroke, and 60.5% of ASCVD death were attributable to not achieving all the seven ideal CVH metrics. After adjusting effects of ideal health factors, having four ideal health behaviors could independently bring adults health benefits in preventing 17.4% of ASCVD, 18.0% of CHD, 16.7% of stroke, and 10.1% of ASCVD death. Among all the seven CVH metrics, to keep with ideal blood pressure(BP) implied the largest public health gains against various ASCVD events(PAR% between 33.0% and 47.2%), while ideal diet was the metric most difficult to be achieved in the long term. Our study indicates that the more ideal CVH metrics adults have, the less ASCVD burden there is in China. Special efforts of health education and behavior modification should be made on keeping ideal BP and dietary habits in general Chinese population to prevent the epidemic of ASCVD.

Assessing Cardiovascular Health Using Life＇s Simple 7 in a Chinese Population Undergoing Stroke Prevention

Background： The American Heart Association/American Stroke Association proposed a metric called Life＇s Simple 7 （LS7） to define cardiovascular health （CVH）. The presence of a large number of ideal components of CVH is associated with lower cardiovascular disease and all-cause mortality. We aimed to assess CVH using LS7 in a Chinese population undergoing primary and secondary stroke prevention. Methods： Patients with either ischemic stroke or cardiovascular risk factors were enrolled in the study from October 2010 to July 2013. LS7 components were scored as poor （0 points）, intermediate （1 point）, or ideal （2 points）. The overall LS7 score was categorized as inadequate （0-4）, average （5-9）, or optimal （10-14） CVH. The Chi-square test, Mann-Whitney U-test, and Kruskal-Wallis test were used. Results： In total, 706 patients were enrolled. （1） The distribution of the overall LS7 score （n = 255） indicated that 9.4%, 82.4%, and 8.2% of the patients had inadequate, average, and optimal CVH, respectively. The proportion of patients with optimal CVH undergoing secondary stroke prevention was lower than that for patients undergoing primary stroke prevention （3.8% vs. 12.8%, P = 0,005）. The vast laaajority of participants （76.1%） presented with 〈2 ideal health components. （2） The proportions of patients with poor, intermediate, and ideal status, respectively, lbr the following LS7 components were assessed： Total cholesterol （n = 275; 5.1%, 73.8%, and 21.1%）, blood pressure （11 = 351 ; 32.5%. 59.0%, and 8.5%）, blood glucose （n = 280; 9.3%, 39.6%, and 51.1%）, physical activity （n = 540; 90.7%, 8.7%, and 0.6%）, diet （n = 524; 0.2%. 92.4%, and 7.4%）, smoking （n = 619： 20.7%, 2.9%, and 76.4%）, and body mass index （n = 259; 6.6%, 35.5%, and 57.9%）. Conclusions： Few Chinese patients undergoing stroke prevention had optimal CVH （determined using LS7）. Additionally, fewer patients undergoing secondary prevention had optimal CVH than those undergoing primary prevention. In particular, physical activity and diet status in this population require improvement.

Factors Affecting Children’s Cholesterol Levels with a View to Prevent Cardiovascular Disease—The Unique Benefits of Health Screening at the Elementary School

Background: The prevention of cardiovascular disease (CVD) can substantially contribute to reducing the mortality rate across countries. The level of interest in cholesterol among experts increases when the subjects are elderly and obese individuals. However, specialists do not recommend that children should receive the cholesterol test. The objective of this study was to investigate the distribution of cholesterol levels among the children of public school and their parents’ lifestyles that are associated with cholesterol levels, and to assess the need for and utility of cholesterol testing in school settings. Methods: The study investigated a group of 226 fourth-grade public school children aged between 9 and 10 years and guardians in Akitakatacity of Hiroshima Prefecture, Japan. Multiple regression analyses were performed with the logarithmic value of cholesterol levels as a response variable, awareness about lifestyles and health of children as an explanatory variable, and child’s sex and body mass index (BMI) as moderating variables. Using questionnaires about lifestyles, the step-down procedure was applied in multiple regression analyses to narrow down relevant lifestyle variables. Results: The percentage of children with the high total cholesterol (TC) value was about 15 and with low-density lipoprotein (LDL) cholesterol value was about 10. Children with low high-density lipoprotein (HDL) cholesterol value were 5%. Treatment was not required according to the comprehensive assessment. Cholesterol levels were associated with the situation of the children and their guardians as follows, guardian need to consider the food, and child has the correct knowledge about food like how to eat snacks. Conclusions: Children had poor cholesterol levels. From childhood, along with the parents, there is a need to learn about appropriate level of cholesterol for CVD prevention.

Relationship changes in lifestyle, cardiovascular risk factors, and mental health in Japanese workers: A four-year follow up with high-risk and population strategies of the occupational health promotion (HIPOP-OHP) study

Background: Cardiovascular diseases (CVD) are major causes of death in Japan, and controlling the risk factors for CVD is an important public health task. Lifestyle factors, for example, diet and stress, have impacts on risk factors such as hypertension and hyperlipidemia. Deterioration of mental health is related to CVD pathogenesis. Aim: We investigated the relationships between levels of mental health, 4-year changes in lifestyle, and CVD risk factors among Japanese workers, using the SF-36 (Japanese version), which is a comprehensive scale measuring health-related quality of life. We hypothesized that workers’ mental health levels would influence 4-year changes in their lifestyles and CVD risk factors. Methods: Data from the High-Risk and Population Strategy for Occupational Health Promotion (HIPOP-OHP) study, which were collected by examination and administration of the SF-36, were used. The relationships between mental health levels at baseline, lifestyle chan- ges, and cardiovascular risk factors were longitudinally analyzed. Subjects with total SF-36 scores ≥65 were classified as the “Good Mental Health Group,” and those with total scores <65 were classified as the “Poor Mental Health Group.” Results: Multiple logistic regression analyses showed that, as compared to people who had poor mental health, those who had good mental health at baseline had a significantly higher probability of good maintenance of improvements in body mass index, (OR = 1.20, 95% CI: 1.03 - 1.39), blood pressure (OR = 1.20, 95% CI: 1.01 - 1.43), total cholesterol (OR = 1.07, 95% CI: 0.86 - 1.33) and HDL cholesterol (OR = 1.26, 95% CI: 1.07 - 1.47). Conclusion: Japanese workers with good mental health tend to improve or maintain good lifestyle conditions and minimize CVD risk factors, while those with poor mental health generally have difficulty improving their lifestyles and lowering their CVD risk.

Cardiovascular Risk in Adults and its Association with Health Services Utilization. ENSANUT 2018-2019

Background The use of health services by the adult population is related to cardiovascular risk and its stratification. Cardiovascular risk (CVR) stratification should be a tool for the assessment of the patients and the appropriate control during the process of medical care and utilization of health services for the adults. Objective Evaluate the association between cardiovascular risk (CVR) in adults and the utilization of health services. Material and Methods A secondary analysis was performed of the data from the National Health and Nutrition Survey (ENSANUT) 2018-2019. The CVR classification (risk score) was obtained in 43,070 adults with a previous diagnosis (self-report) and 1,237 adults newly diagnosed. Independent, risk factors and the association between groups of CVR and utilization of preventive, outpatient and hospital services were analyzed. Results More than 85% of adults interviewed have some degree of CVR. Almost half of them have low CVR (48.2%). Older adults with social security predominate in the group with high and very high CVR. Seventy-five percent of adults recently diagnosed have low CVR. In both, there is very little utilization of health services. For adults previously diagnosed CVR, the higher the CVR, the greater the likelihood of utilization of outpatient, preventive and hospital services, in contrast to adults without CVR independent of the marital status, sex, health institution and socioeconomic level. Conclusion The results give evidence of areas of opportunity for improvement in the quality of health services. The evaluation of CVR in primary care and promotion and prevention of CVR should be strengthened.
