Hyperreactivity to stress may be one explanation for the increased risk of cardiovascular disease (CVD) in individuals with essential hypertension. We investigated blood lipid reactivity to the Montreal Imaging Stress Task (MIST), a psychosocial stressor, in hypertensive and normotensive men and tested for prospective associations with biological risk factors. Fifty-six otherwise healthy and medication-free hypertensive and normotensive men underwent the MIST. We repeatedly measured cortisol and blood lipid profiles (total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG)) immediately before and up to 1 h after stress. Lipid levels were corrected for stress hemoconcentration. Thirty-five participants completed follow-up assessment 2.9 ± 0.12 (SEM) years later. CVD risk was assessed by prospective changes in TC/HDL-C ratio, IL-6, D-dimer, and HbA1c from baseline to follow-up. The MIST induced significant changes in all parameters except TC (p-values ≤ 0.043). Compared with normotensives, hypertensives had higher TC/HDL-C-ratio and TG (p-values ≤ 0.049) stress responses. Blood lipid stress reactivity predicted future cardiovascular risk (p = 0.036) with increases in HbA1c (ß = 0.34, p = 0.046), IL-6 (ß = 0.31, p = 0.075), and D-dimer (ß = 0.33, p = 0.050). Our results suggest that the greater blood lipid reactivity to psychosocial stress in hypertensives, the greater their future biological CVD risk. This points to lipid stress reactivity as a potential mechanism through which stress might increase CVD risk in essential hypertension.

Cvd Risk

Background Cardiovascular disease (CVD), is the primary cause of morbidity and mortality in patients with diabetes and have approximately - two to four times higher CVD rate than adult without diabetes. Low density lipoprotein cholesterol (LDL-C) is primarily used as the marker of cardiovascular risk in diabetes despite its several limitations. Although several newer markers of CVD are emerging, no marker has been established in Nepal. Objectives The study was designed to evaluate the non-high-density-lipoprotein- cholesterol(Non-HDL-C) and Total Cholesterol to High density lipoprotein cholesterol (TC:HDL-C ratio) as CVD risk marker in diabetes mellitus. Methods The study was conducted in the Department of Bbiochemistry, Kathmandu University School of Medical Sciences. The study comprised of 76 diabetic subjects and 60 non-diabetic subjects. The anthropometric and biochemical parameters were measured. The Non-HDL-C and TC:HDL-C ratio were also calculated employing their respective formula. Results Body mass index (BMI), waist circumference (WC), blood pressure and lipid parameters were significantly different between diabetic subjects and non-diabetic subjects. There was increased non-HDL-C and TC:HDL-C ratio in subjects with diabetes mellitus. Furthermore, statistically significant correlations of non-HDL-C and TC:HDL-C ratio were obtained with BMI, WC, total cholesterol, HDL-C and LDL-C in diabetic subjects. Conclusions The present study observation revealed that the Non-HDL-C and TC: HDL-C strongly correlate with established independent risk factors such as obesity(WC), elevated blood pressure, HDL-C and LDL-C in diabetes. Thus, the evaluation of Non-HDL-C and TC: HDL-C ratio can be used as the simple, cost-effective and cumulative marker of cardiovascular risk in diabetes mellitus.http://dx.doi.org/10.3126/kumj.v8i4.6239 Kathmandu Univ Med J 2010;8(4):398-404

Abstract Background Aim of the study was to assess trends of cardiovascular risk factors among Siberian adolescents during the last 30 years including period of Russian reforms (1989-2019). Methods Seven cross-sectional surveys of representative samples of school children aged 14-18 since 1989 (every 5 years) were carried out. Body mass index (BMI), systolic and diastolic blood pressure, serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured. Self-reported smoking and physical activity rates were obtained. To define overweight the sex- and age-specific IOTF cutoffs for BMI were used. Hypertension (HT) and lipid disorders were revealed according to international criteria. Results Prevalence of high TC significantly decreased from 22 to 4% (p < 0,01) in males and from 32 to 17% (p < 0,05) in females. High LDL-C showed similar trends. Prevalence of low HDL-C was stable with some fluctuations. In the period of Russian reforms (1989-1999) the prevalence of overweight significantly decreased from 12% in boys and from 14% in girls in 1989 to 4% in 1999 (p < 0,01). Since 2003 rapid increasing of overweight was observed. Trends of HT have shown double decreasing during the reform period and stabilization in the post-reform time. So, since 2003 discordant trends in HT and overweight were revealed. Physical activity was stably low in boys (49-55%) and girls (83-73%). Average weekly screen time doubled from 15 (2009) to 30 h/w (2019), p < 0,05. Cigarette smoking rates in boys dramatically decreased from 45% (1989) to 3% (2019), in girls - from 19% to 5% (p < 0,01). Smoking of electronic devices was registered in 2019: 6% among boys and 3% among girls. Conclusions Obtained data indicate on trends to reduction in CVD risk profile among Siberian adolescents during the period of Russian reforms. Discordant trends of HT and overweight were revealed. The study was supported by RFBR grant 19-013-00800. Key messages Long time changes in cardiovascular risk profile among Siberian adolescents were registered. Against the background of a decrease in combustible smoking among adolescents, electronic smoking began to register.

Context: Thyroid dysfunction may have detrimental effects on patient outcomes. Few studies have assessed this issue in patients with secondary hypothyroidism. Objective: Our objective was to test the hypothesis that thyroid hormone status has an impact on cardiovascular risk factors in adult patients with hypopituitarism. Design and Setting: This was a retrospective observational study (1993–2012) at a tertiary referral university hospital. Patients: All GH-deficient patients starting GH replacement (1993–2009) with measured free T4 (fT4) (n = 208). Baseline fT4 defined patients as TSH-sufficient and TSH-deficient (further divided into tertiles according to baseline fT4; first tertile had lowest fT4). Main Outcome Measures: Anthropometric (body mass index [BMI], waist circumference, total fat (fat mass) and lean body mass [LBM]) and biochemical (lipids and fasting plasma glucose) data were collected at baseline and a median 4.1 years after commencement of GH. Results: At baseline, fT4 was negatively associated with BMI and waist circumference, but positively with high-density lipoprotein, independent of age, gender, and IGF-I (SD score). Only first-tertile TSH-deficient patients had higher BMI (P = .02), fat mass (P = .03), total cholesterol (P = .05), triglycerides (P < .01), and waist circumference (P = .01), and lower high-density lipoprotein cholesterol (P = .03) as compared with TSH-sufficient patients. At follow-up, IGF-I, LBM, and plasma glucose had increased in all subgroups (P < .01). The change in fT4 (ΔfT4) (follow-up − baseline) was negatively correlated to ΔBMI, ΔLBM, Δtotal cholesterol, and Δlow-density lipoprotein cholesterol (all P < .05, adjusted for ΔIGF-I and ΔGH and hydrocortisone dose). The negative correlation to Δtotal cholesterol and Δlow-density lipoprotein cholesterol persisted only in first-tertile TSH-deficient patients. Conclusion: This single-center study over a 20-year period has strengthened the importance of improved awareness of thyroid status and optimal thyroid replacement of hypopituitary patients to reduce cardiovascular risks in hypopituitary patients.

Abstract Background: Experimental studies found that the functionality of high density lipoprotein cholesterol (HDL-C) may be lost in the presence of diabetes mellitus (DM). We prospectively tested whether DM modified the association between HDL-C concentrations and cardiovascular disease (CVD).Methods: Included were 91,354 Chinese adults (8,244 participants with DM and 83,110 participants without DM) without use of lipid-lowering drugs and free of CVD or cancer at baseline (2006). The primary endpoint of interest was a composite of CVD (myocardial infarction, ischemic stroke and hemorrhagic stroke). Cumulative average HDL-C concentrations were calculated from all available HDL-C measures at baseline (2006) and during the follow-up period (2008, 2010, 2012 and 2014).Results: During a mean of 10.4 year of follow-up, there were 5,076 CVD events identified. Presence of DM significantly modified the association between HDL-C concentrations and CVD risk (Pinteraction =0.003). The association between HDL-C concentrations and CVD followed a U-shaped curve in individuals without DM (Pnonlinearity <0.001). The adjusted hazard ratio (HR) of CVD was 1.25 (95% confidence interval (CI): 1.06-1.48) for HDL-C concentrations <1.04 mmol/L and 1.80 (95% CI: 1.56-2.07) for HDL-C concentrations >2.07 mmol/L, relative to the lowest risk group (HDL-C concentrations of 1.30-1.42mmol/L). In participants with DM, higher HDL-C concentrations were associated with a higher risk of CVD, in a dose-response manner (Pnonlinearity =0.44; Ptrend <0.001). The adjusted HR of CVD was 1.63 (95%CI: 1.20-2.20) for HDL-C concentrations >2.07 mmol/L, relative to HDL-C concentrations of 1.30-1.42mmol/L. Conclusion: High HDL-C concentrations were paradoxically associated with increased risk of composite CVD outcomes in individuals with or without DM. However, low HDL-C concentrations failed to predict future CVD risk in individuals with DM.

The relationships between maternal dietary patterns and blood lipid profile during pregnancy have not been well understood. We aimed to analyze the dietary patterns of pregnant women and their associations with blood lipid concentrations during pregnancy. A cohort of 1008 Chinese pregnant women were followed from 10–15 weeks of gestation to delivery. Their dietary patterns were identified using a principal component analysis. The relationships between dietary pattern score and maternal blood lipid concentrations were assessed using both multivariate linear regression models and generalized estimating equation (GEE) models. Five different dietary patterns were identified. GEE showed that a high score for the fish-shrimps pattern was associated with higher concentrations of total cholesterol (TC) (β = 0.11), low-density lipoprotein cholesterol (LDL-C) (β = 0.07), and high-density lipoprotein cholesterol (HDL-C) (β = 0.03), with all p values < 0.001. In contrast, a high tubers-fruit-vegetables pattern score was associated with lower concentrations of TC (β = −0.12), LDL-C (β = −0.07), and HDL-C (β = −0.03), with all p values < 0.001. In addition, dietary protein, carbohydrate, and cholesterol intake significantly contributed to the associations between the fish-shrimps dietary pattern and blood lipid concentrations. Predominant seafood consumption is associated with higher cholesterol concentrations, whereas predominant tuber, fruit, and vegetable consumptions are associated with lower cholesterol concentrations during pregnancy.

BackgroundFor childhood onset type 1 diabetes (T1D), the pathogenesis of atherosclerosis is greatly accelerated and results in early cardiovascular disease (CVD) and increased mortality. However, cardioprotective interventions in this age group are not routinely undertaken.AimsTo document prevalence of cardiovascular risk factors from diagnosis of childhood T1D and their relationship with disease duration and ethnicity.MethodsRoutinely collected clinical records for 565 children with T1D were retrospectively analyzed. Data were collected from diagnosis and at routine check-ups at pediatric diabetes clinics across Barts Health National Health Service Trust. Age at diagnosis was 8.5 years (0.9–19.4). Mean follow-up 4.3 years (0–10.8). 48% were boys and 60% were non-white. Linear longitudinal mixed effects models were used to evaluate relationships between risk factors and diabetes duration.ResultsCVD risk factors were present at first screening; 33.8% of children were overweight or obese, 20.5% were hypertensive (elevated diastolic blood pressure (BP)) and total cholesterol, low-density lipoprotein-cholesterol and high-density lipoprotein-cholesterol were abnormal in 63.5%, 34.2% and 22.0%, respectively. Significant associations between diabetes duration and annual increases of body mass index (0.6 kg/m2), BP (0.1 SD score) and lipids (0.02–0.06 mmol/L) were noted. Annual increases were significantly higher in black children for BP and Bangladeshi children for lipids. Bangladeshi children also had greatest baseline levels.ConclusionsCVD risk factors are present in up to 60% of children at diagnosis of T1D and increase in prevalence during the early years of the disease. Commencing screening in younger children and prioritizing appropriate advice and attention to ethnic variation when calculating risk should be considered.

Abstract Background Non-high-density lipoprotein cholesterol (non-HDL-C) may be an independent risk factor for cardio-cerebrovascular disease (CVD); however, the cutoff level in patients on maintenance hemodialysis (MHD) is unknown. Methods This was a retrospective multicenter study of MHD patients treated at 10 dialysis centers in Guangdong Province from July 1, 2016, to April 1, 2017. Laboratory test data were collected and CVD complications and outcomes recorded. Results In total, 1288 eligible patients were included in this study; the non-HDL-C interquartile range was 2.76 (2.24–3.45) mmol/L. Over a median follow-up time of 24 months, 141 patients developed CVD. The non-HDL-C level was a principal risk factor for such events (P < 0.05; 95% confidence interval 0.800–0.842). The maximum Youden index was 0.549 and the best cutoff > 3.39 mmol/L. Conclusion Higher baseline non-HDL-C levels may increase the CVD risk in MHD patients. Thus, non-HDL-C effectively predicts CVD.

Aims: To investigate changes in cardiovascular risk factors over 14 years in relation to diabetes status. Methods: The study is based on 10,327 subjects who attended the Tromsø Study in 1994 and were screened again in 2007–8. At baseline there were 79 prevalent cases, and 397 incident cases of type 2 diabetes mellitus (DM2) were diagnosed between 1994 and 2008. Results: Cases with DM2 had decreasing levels of high-density lipoprotein cholesterol (HDL-C), total cholesterol and blood pressure (BP) and increasing levels of triglycerides, body mass index (BMI), and anti-hypertensive treatment during 14 years of follow-up. Despite decreasing BP, more than 75% of the treated cases had BP above 135/80 at the end of follow-up. Similarly, less than 35% of incident cases using statins had low-density lipoprotein cholesterol (LDL-C) below the recommended threshold value of 2.6 mmol/l. Conclusions: Despite greater relative reduction in cardiovascular risk factors among people with DM2 compared to those without, treatment targets were met in less than 50% of subjects with DM2. Thirteen percent reached the combined targets for glucose, BP and LDL-C control. This indicates a need for more effective strategies to control cardiovascular risk factors especially among individuals with DM2.

Abstract Background Dyslipidemia is a major cardiovascular risk factor and common in diabetes patients. Most guidelines focus on optimal lipid levels, while variation of lipid profiles is far less discussed. This study aims to investigate the association of visit-to-visit variability in blood lipids with all-cause, cardiovascular, and non-cardiovascular mortality in patients with type 2 diabetes. Methods We identified 10,583 type 2 diabetes patients aged ≥ 30 years with follow-up ≥ 3 years and who participated in the Diabetes Care Management Program at a medical center in Taiwan. Variability in lipid profiles within 3 years after entry was calculated using coefficient of variation. Cox proportional hazard models were used to evaluate lipid variability in relation to subsequent mortality. Results Over a mean follow-up of 6.4 years, 1838 all-cause deaths (809 cardiovascular deaths) were observed. For each 10% increase in variability in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol, the hazard ratios (95% confidence intervals) of all-cause mortality were 1.30 (1.22–1.37), 1.05 (1.01–1.09), and 1.10 (1.03–1.16), respectively; those of cardiovascular mortality were 1.27 (1.16–1.39), 1.08 (1.02–1.15), and 1.16 (1.07–1.27), respectively. Each 10% increase in high-density lipoprotein cholesterol variability conveyed 31% greater risk of non-cardiovascular mortality. High variability in total cholesterol and low-density lipoprotein cholesterol increased all-cause mortality in subgroups of nonsmoking, regular exercising, non-dyslipidemia, and more severe status of diabetes at baseline. Conclusions Blood lipid variability except for triglyceride variability was associated with all-cause and cardiovascular mortality in patients with type 2 diabetes.
