RESUMO
BACKGROUND: Type 2 Diabetes Mellitus (T2DM) has become a major health concern with an increasing prevalence and is now one of the leading attributable causes of death globally. T2DM and cardiovascular disease are strongly associated and T2DM is an important independent risk factor for ischemic heart disease. T-wave abnormalities (TWA) on electrocardiogram (ECG) can indicate several pathologies including ischemia. In this study, we aimed to investigate the association between T2DM and T-wave changes using the Minnesota coding system. METHODS: A cross-sectional study was conducted on the MASHAD cohort study population. All participants of the cohort population were enrolled in the study. 12-lead ECG and Minnesota coding system (codes 5-1 to 5-4) were utilized for T-wave observation and interpretation. Regression models were used for the final evaluation with a level of significance being considered at p < 0.05. RESULTS: A total of 9035 participants aged 35-65 years old were included in the study, of whom 1273 were diabetic. The prevalence of code 5-2, 5-3, major and minor TWA were significantly higher in diabetics (p < 0.05). However, following adjustment for age, gender, and hypertension, the presence of TWAs was not significantly associated with T2DM (p > 0.05). Hypertension, age, and body mass index were significantly associated with T2DM (p < 0.05). CONCLUSIONS: Although some T-wave abnormalities were more frequent in diabetics, they were not statistically associated with the presence of T2DM in our study.

BACKGROUND AND AIM: The current study investigated the association between triglyceride-glucose index (TyG) and triglyceride/HDL-C indices and coronary atherosclerosis extent in diabetic and non-diabetic patients. METHODS AND RESULTS: In this case-control study, 1538 individuals were classified into two groups: diabetic and non-diabetic subjects. Each group was further grouped as follows: (1) angiography+ (2) angiography-and (3) subjects without a history of cardiovascular diseases. The TyG and TG/HDL-C indices were compared between the subgroups of the diabetic (n = 407) and non-diabetic (n = 1131) groups. In both diabetic and non-diabetic patients, there was no significant association in TG/HDL-C; and diabetic subjects, angiography+ and angiography-groups had significantly higher TyG (p < 0.05). A high TyG index was associated with a higher risk of angiography+ (OR: 1.883 (1.410-2.514)). CONCLUSIONS: The TyG index, but not the TG/HDL-C, was an independent marker for predicting the severity of coronary stenosis in non-diabetic patients.

BACKGROUND: Coronary artery disease (CAD) is known as the leading cause of disability and death globally. Anxiety disorders are also recognized as common types of mental disorders that substantially impact global health. Iran ranks among the countries with a high incidence of CAD and anxiety disorders. Therefore, the present study aims to determine the potential association and epidemiological aspects of anxiety and CAD within the population of Mashhad, the second most popoulos city in Iran. METHODS: The present study is based on extracted data from the Mashhad stroke and heart atherosclerotic disorder (MASHAD) study which is a 10-year prospective cohort study intended to assess the effects of various CAD risk factors among Mashhad city residents. Anxiety scores were assessed at the baseline using Beck Anxiety Inventory and individuals were classified based on the BAI 4-factor structure model which included autonomic, cognitive, panic, and neuromotor components. Accordingly, the association between baseline anxiety scores and the BAI four-factor model with the risk of CAD events was analyzed using SPSS software version 21. RESULTS: Based on the results, 60.4% of the sample were female, and 5.6% were classified as having severe forms of anxiety. Moreover, severe anxiety was more prevalent in females. Results showed a 1.7% risk of CAD (p-value < 0.001) over 10 years with one unit increase in anxiety score. Based on the 4-factor model structure, we found that only panic disorder could significantly increase the risk of CAD by 1.1% over the 10-year follow-up (p-value < 0.001). CONCLUSION: Anxiety symptoms, particularly panic disorder, are independently and significantly associated with an increased overall risk of developing CAD over a 10-year period. Therefore, further studies are warranted to investigate the mechanisms through which anxiety may cause CAD, as well as possible interventions to mitigate these processes.

AIM: QTc interval prolongation is a growing global issue which can cause torsades de pointes, a potentially fatal arrhythmia. We aimed to identify risk factors for prolonged QT interval in men and women. METHODS: The Mashhad stroke and heart atherosclerotic disorder (MASHAD) cohort study collected electrocardiogram interval data. QT was corrected for heart rate using the Bazett's formula. Ordinal logistic regression with crude (univariable) and adjusted (multivariate) association analyses in the form of odds ratio and corresponding 95% confidence interval (CI) were used to identify the factors associated with QTc prolongation. RESULTS: A total of 8878 individuals including 5318 females and 3560 males, aged 35 to 65 years, were included in this cross-sectional study. Participants with QTc prolongation were more likely to be older and have hypercholesterolemia, hypertension (HTN), and Type 2 diabetes mellitus (T2DM), but to have lower levels of physical activity (P < 0.05). Age (OR = 1.68, 95%CI = 1.18-2.39), hypercholesterolemia (OR = 1.77, 95%CI = 1.24-2.51), HTN (OR = 1.36, 95%CI = 1.06-1.73), T2DM (OR = 1.59, 95%CI = 1.19-2.13), severe anxiety (OR = 1.80, 95%CI = 1.05-3.11) and mild depression (OR = 1.38, 95%CI = 1.01-1.88) were independent risk factors for prolonged QTc interval in men. For women, only HTN (OR = 1.29, 95%CI = 1.02-1.63) and T2DM (OR = 1.50, 95%CI = 1.14-1.97) were independent risk factors. CONCLUSIONS: Older age, Hypercholesterolemia, HTN, T2DM, severe anxiety and mild depression in men, and HTN and T2DM in women were associated with high risk of prolonged QTc interval. Healthcare practitioners should be aware of the risk factors of QTc interval prolongation and should exercise caution in the management of certain patients.

BACKGROUND AND AIM: Coronavirus disease (COVID-19) is an infectious disease that can spread very rapidly with important public health impacts. The prediction of the important factors related to the patient's infectious diseases is helpful to health care workers. The aim of this research was to select the critical feature of the relationship between demographic, biochemical, and hematological characteristics, in patients with and without COVID-19 infection. METHOD: A total of 13,170 participants in the age range of 35-65 years were recruited. Decision Tree (DT), Logistic Regression (LR), and Bootstrap Forest (BF) techniques were fitted into data. Three models were considered in this study, in model I, the biochemical features, in model II, the hematological features, and in model II, both biochemical and homological features were studied. RESULTS: In Model I, the BF, DT, and LR algorithms identified creatine phosphokinase (CPK), blood urea nitrogen (BUN), fasting blood glucose (FBG), total bilirubin, body mass index (BMI), sex, and age, as important predictors for COVID-19. In Model II, our BF, DT, and LR algorithms identified BMI, sex, mean platelet volume (MPV), and age as important predictors. In Model III, our BF, DT, and LR algorithms identified CPK, BMI, MPV, BUN, FBG, sex, creatinine (Cr), age, and total bilirubin as important predictors. CONCLUSION: The proposed BF, DT, and LR models appear to be able to predict and classify infected and non-infected people based on CPK, BUN, BMI, MPV, FBG, Sex, Cr, and Age which had a high association with COVID-19.

BACKGROUND: Twelve-lead electrocardiogram (ECG) is a common and inexpensive tool for the diagnostic workup of patients with suspected cardiovascular disease, both in clinical and epidemiological settings. The present study was designed to evaluate ECG abnormalities in Mashhad population. METHODS: ECGs were taken as part of MASHAD cohort study (phase1) and were coded according to the Minnesota coding criteria. Data were analyzed using SPSS. RESULTS: Total 9035 ECGs were available for final analysis including 3615 (40.0%) male and 5420 (60.0%) female. Among ECG abnormalities precordial Q wave, major T-wave abnormalities, inferior Q wave, sinus bradycardia, and left axis deviation were the most prevalent abnormalities. The frequency of precordial and inferior Q wave, inferior QS pattern, major and minor ST abnormalities, major and minor T abnormalities, Wolff-Parkinson-White and Brugada pattern, sinus bradycardia, sinus tachycardia, left axis deviation, ST elevation, and tall T wave were significantly different between two genders. Moreover, the frequency of Q wave in precordial and aVL leads, QS pattern in precordial and inferior leads, major and minor T-wave abnormalities, Wolff-Parkinson-White, atrial fibrillation, sinus bradycardia, left axis deviation, and ST elevation were significantly different in different age groups. A comparison of the heart rate, P-wave duration, and QRS duration between men and women indicated that there was a significant difference. CONCLUSIONS: Our finding indicated that the prevalence ECG abnormalities are different between men and women and also it varied in different age groups.

BACKGROUND: Anxiety and depression are crucial public health issues, affecting the rising in hospitalizations and death. Anxiety and depression can worsen hypertension and vice versa. OBJECTIVE: The current study has investigated the effects of celery seed extract, as a drug supplement, with the active ingredient of 3-n-butylphthalide, on mental problems primarily anxiety and secondary depression in hypertensive patients. DESIGN: The current study was a randomized, triple-blind, placebo-controlled, cross-over, 4-week clinical trial with a 4-week washout period. Fifty hypertensive patients received 4 placebo or celery seed extract capsules (1.34 g per day) for 4 weeks as a supplement to their usual medication regimen. The blood pressure parameters were assessed using 24-h ambulatory blood pressure monitoring device. Anxiety and depression and their wide range of symptoms were evaluated using Beck anxiety and depression inventories (BAI and BDI). RESULTS: In the celery treatment step, the mean reduction in BAI and BDI scores were 6.78 (P < 0.001) and 3.63 (P < 0.01), respectively. Some symptoms of anxiety including unable to relax, nervousness, numbness, dizziness, flushed face, sweating, and breathing difficulty were significantly improved by celery consumption (P < 0.001). Celery could decrease symptoms of depression such as sadness, crying, loss of energy, insomnia, irritability, fatigue, loss of interest in sex, and punishment feeling (P < 0.01). The mean reduction in blood pressure parameters was also significant during celery therapy (P < 0.001). CONCLUSIONS: The psychometric properties of anxiety and depression were investigated and the results were promising. The results indicated the anti-anxiety and anti-depressive properties of celery seed extract as a supplement in hypertensive patients. CLINICAL TRIAL REGISTRATION: Registry name: Iranian Registry of Clinical Trials (IRCT), Registration number: IRCT20130418013058N8, Registration link: https://www.irct.ir/trial/30021 . The study was carried out between 2018-09-21 and 2020-07-20.

In the present work, the antihypertensive effects of celery seed extract (Apium graveolens) with active ingredients, such as 3-n-butylphthalide, were studied as a drug supplement in the treatment of hypertension. This study was a randomized, triple-blind, placebo-controlled, cross-over clinical trial. Fifty-two patients were divided into two groups (celery and placebo) and completed the two-step clinical trial. Four celery seed extract capsules (totally 1.34 g per day) or 4 placebo capsules per day were administered to the patients during a 4-week clinical trial. The blood pressure was assessed using a 24-hr ambulatory blood pressure monitoring method. In celery group, systolic blood pressure changed from 141.2 ± 5.91 to 130.0 ± 4.38 mmHg (p < .001) while diastolic blood pressure changed from 92.2 ± 5.74 to 84.2 ± 4.87 mmHg (p < .001). Moreover, the mean arterial blood pressure changed from 108.5 ± 5.76 to 99.5 ± 4.66 mmHg (p < .001), and pulse pressure decreased from 49.0 ± 6.21 to 45.8 ± 6.01 mmHg (p < .01). However, no significant changes were observed in placebo group in terms of the above-mentioned parameters (p > .05). Furthermore, no significant side effect was reported in the celery group, compared to the placebo group (p > .05). The results were promising and indicated the therapeutic effects of celery seed extract as a supplement in the management of hypertension.

The present study was conducted to evaluate the safety of celery seed extract (Apium graveolens), as a medicinal herb with active ingredients such as 3-n-butylphthalide (NBP), in hypertensive patients. This study was a randomized, triple-blind, placebo-controlled, cross-over clinical trial. Hypertensive patients (51 participants) received 4 celery seed capsules (a total of 1.34 g extract per day) or 4 placebo capsules per day for 4 weeks as a supplement to their usual medication regimen. The results indicated that the celery seed capsule not only was safe for hypertensive patients but also caused a reduction in BP, FBS, and lipid profile values. Also, it had beneficial effects on kidney and liver functions. No significant change was observed in blood cells and serum electrolytes (p > 0.05). The mean reduction in BUN and SCr were 3.43 and 0.075 mg/dL, and in SGPT and SGOT were 4.08 and 3.03 U/L, respectively (p < 0.05). FBS reduced from 108.53 to 97.96 mg/dL after 4 weeks of celery administration (p < 0.01). The decrease in TC, TG, LDL, and increase in HDL were 16.37, 16.22, 11.84, and 2.52 mg/dL, respectively (p < 0.001). According to the promising results of this clinical trial, celery seed extract can be considered a safe supplement for hypertensive patients. The study is limited by the small sample size; therefore, larger randomized trials are required.

BACKGROUND: Coronary-artery-disease (CAD) is the leading cause of death worldwide, and hence there is a need to identify reliable markers for identifying individuals at high risk of developing CAD. Interleukin-10 (IL-10) is an anti-inflammatory cytokine that is associated with an increased risk of developing both atherosclerosis and acute coronary events. The study aimed to explore the association of a genetic variant in IL-10 with the risk of developing CAD and the severity of the disease. To further explore, a systematic review and meta-analysis was performed. The cumulative results of the relationship between IL and 10 -592 C > A polymorphism and CAD in Iranian population have also been presented. METHODS: In this cross sectional study, a total of 948 individuals including 307 healthy controls and 641 patients that among cases, four hundred and fifty-five of the patients had > 50% stenosis (angiogram positive group) and 186 patients had < 50% stenosis (angiogram negative group) were recruited from the Mashhad-Stroke and Heart-Atherosclerotic-Disorders cohort. Genotyping for the IL-10 -592 C > A polymorphism was performed using a PCR-RFLP technique, and statistical analysis undertaken by univariate and multivariate analyses. PubMed, Google Scholar and Scopus were searched for papers related to this polymorphism up to October 2019. The Meta-analysiswas done based on the random effect model using a Meta-analysis. RESULTS: In our study, the frequency of the variant A allele of the IL-10 -592 C > A was significantly higher in CAD patients than the control group (P value = 0.043). Moreover, subjects carrying AA genotype had a significantly higher risk of CAD (OR: 1.8, 95%CI: 1.04-3.16), p = 0.03), compared to those with the wild type genotype. The results of meta-analysis of 9336 cases and 8461 controls did not also show any significant association between IL and 10 -592 C > A and CAD in dominant and recessive genetic models but only in co-dominant model when fix effect was applied. CONCLUSION: Although our research findings support a significant association of genetic polymorphism in the IL10 gene with cardiovascular diseases, this finding cannot be confirmed in meta-analysis. Further functional analysis and evaluation of this marker in a multicenter setting are needed to establish its value as a risk stratification marker.

BACKGROUND AND OBJECTIVE: Previous studies showed controversial results of the relationship between fluoride exposure through drinking water and elevated blood pressure. We conducted a systematic review and meta-analysis to assess the direct relationship of drinking water fluoride exposure with blood pressure and essential hypertension prevalence in general populations. METHODS: We conducted a systematic search in databases including Web of Knowledge, PubMed, Scopus, and Embase by MeSH and non-MeSH terms for relevant studies with any design published until August 2019, with no limitation in time and language. The pooled effect measure was calculated within a 95% confidence interval (CI). RESULTS: Our search retrieved 630 journal articles, six of which were eligible for data extraction. The random-effects model found significantly higher systolic blood pressure (mean difference = 6.49 mmHg; 95% CI 3.73-9.25; p value < 0.01) and diastolic blood pressure (mean difference = 4.33 mmHg; 95% CI 1.39-7.26; p value < 0.01) in groups exposed to high-fluoride drinking water than in groups exposed to normal/low-fluoride drinking water. A significant relationship was also found between high-fluoride drinking water and essential hypertension (odds ratio = 2.14; 95% CI 1.02-4.49; p value = 0.045). CONCLUSION: The risk of elevated blood pressure increases in the general population of fluoride endemic areas. However, more research is needed to make a firm conclusion about the adverse effects of excess fluoride intake on the cardiovascular system at the individual level.

The dietary inflammatory index (DII) is a novel way of describing diet that has been studied in relation to various health conditions, including cardiovascular disease (CVD) in several populations. We aimed to investigate the association between DII and CVD events among a representative population sample in northeastern Iran. This prospective cohort study was a subsample of 4,672 adults aged 35-65 years, and recruited as part of Mashhad stroke and heart atherosclerotic disorder cohort study population. The DII was computed at baseline according to a 65-item validated food frequency questionnaire. Cox regression was used to determine the association of DII with incident CVD. One hundred twenty-four participants developed CVD (including 24 cases of myocardial infarction [MI], 34 cases of stable angina [SA], and 66 cases of unstable angina [UA]). After adjusting for potential confounding factors, a hazard ratios of 1.06 (95% confidence interval: 0.70-1.60), 1.36 (95% confidence interval: 0.52-3.52), 1.33 (95% confidence interval: 0.60-2.94), and 0.86 (95% confidence interval: 0.48-1.53) were found for total CVD, MI, SA, and UA events, respectively, among the participants with proinflammatory diet (DII ≥ 0) versus those with anti-inflammatory diet (DII < 0). There was no statistically significant association between the DII and total CVD, MI, SA, or UA in this population of middle-aged Iranian men and women.

Cardiovascular disease (CVDs) is the leading cause of morbidity and death worldwide. Most genetic variants could be identified by several genome-wide-association-studies (GWAS), including within genes encoding proteins involved in the AKT/PI3K pathways that are related with an increased risk of metabolic syndrome and CVDs. Therefore, due to the importance of genetic variants in the prognosis of diseases, we examined the genetic polymorphism of AKT-rs1130233 located on chromosome 14 with cardiovascular risk factors. In this cross-sectional study, 721 subjects recruited from the Mashhad-Stroke and Heart-Atherosclerotic-Disorders (MASHAD) cohort study. The participants including 257 subjects with metabolic syndrome, 144 subjects with cardiovascular disease and 320 subjects as a control group. Anthropometric, biochemical and demographic information measures were prepared. Dietary assessment was managed by 24h dietary recall. DNA extraction and genotyping were carried out by using the TaqMan real-time-PCR based method. The association of AKT rs1130233 locus with dietary intakes, metabolic syndrome and cardiovascular risk factors were assessed. Data were analyzed by using SPSS 21 software. Frequencies of genotypes AA, AG and GG of the AKT rs1130233 polymorphism were 12.6%, 44.5% and 42.9% in subjects with metabolic syndrome and 9.7%, 39.6% and 50.7% in subjects with cardiovascular disease, respectively. The frequency of allele A and G in cardiovascular disease and metabolic syndrome population were 29.5%, 70.5% and 34.8%, 65.2%, respectively. We have found no significant association between the AKT rs1130233 polymorphism with cardiovascular risk factors and metabolic syndrome. The results of dietary intake showed that the levels of phosphorus intake (p=0.008), calcium intake (p=0.007) and iodine intake (p=0.04) were different in subjects with and without metabolic syndrome. And also, energy intake was significantly different in subjects with cardiovascular disease (p=0.01) compared to the control group. Our findings suggest that AKT rs1130233 was not associated with the risk of metabolic syndrome and cardiovascular disease in the Iranian population. More studies are needed to validate our results. We did functional analysis, due to certify our investigation about value of this genetic biomarker for CVD risk.

BACKGROUND: Systemic inflammation is emerging as an important factor in the etiology of psychiatric disorders such as depression and anxiety. Therefore, the inflammatory potential of the diet may also be an etiological factor for these conditions, and this may be estimated by calculating the dietary inflammatory index (DII®) score. We aimed to investigate the association between DII score and incidence of depression and anxiety among a representative sample in northeastern Iran. METHODS: This cross-sectional study undertook in a sub-sample of 7083 adults aged 35 to 65 years recruited as part of Mashhad stroke and heart atherosclerotic disorder (MASHAD) cohort study population, and after excluding subjects with incomplete data. All participants completed the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI-II), and a validated 65-item food frequency questionnaire (FFQ). Logistic regression was used to evaluate the association between DII score and depression/anxiety score. RESULTS: Of the study participants, 37.1% (n = 2631) were found to have mild to severe depression, and 50.5% (n = 3580) were affected by mild to severe anxiety. After adjusting for confounding factors, in women, the third (OR: 1.41, 95% CI: 1.06-1.88, p-values< 0.05) and fourth quartiles (OR: 1.37, 95% CI: 1.03-1.83, p-values< 0.05) of DII score were associated with increased risk of a high depression score compared to the first quartile of DII score. CONCLUSION: There was a significant association between DII score and severe depression among women but not men in this Iranian population. In order to confirm the association between DII food score, depression, and anxiety, further research is required in different populations, and perhaps an intervention study.

INTRODUCTION: Dyslipidemia may be defined as increased levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), or a decreased serum high-density lipoprotein cholesterol (HDL-C) concentration. Dyslipidemia is an established risk factor for cardiovascular disease (CVD). We aimed to investigate the association of dyslipidemia and CVD events among a population sample from Mashhad, in northeastern Iran. MATERIAL AND METHODS: This prospective cohort study comprised a population of 8698 men and women aged 35-65 years who were recruited from the Mashhad Stroke and Heart Atherosclerotic Disorder (MASHAD) study. Socioeconomic and demographic status, anthropometric parameters, laboratory evaluations, lifestyle factors, and medical history were gathered through a comprehensive questionnaire and laboratory and clinical assessment for all participants. Cox regression model and 95% confidence interval (CI) were used to evaluate the association of dyslipidemia and its components with CVD incidence. RESULTS: After 6 years of follow-up, 233 cases of CVD (including 119 cases of unstable angina [US], 74 cases of stable angina [SA], and 40 cases of myocardial infarction [MI]) were identified in the study population. Unadjusted baseline serum LDL-C, TC, and TG levels were positively associated with the risk of total CVD events among the entire population (HR: 1.54, 95% CI: 1.19-2; P-value< 0.01; HR: 1.53; 95% CI: 1.18-1.98; P < 0.01; HR: 1.57; 95% CI: 1.27-2.03; P < 0.01, respectively). However, after adjusting for confounding factors (age, body mass index [BMI], family history of CVD, smoking status [non-smoker, ex-smoker and current smoker], lipid lowering drug treatment, anti-hypertensive drug treatment, hypertension, healthy eating index [HEI], total energy intake, and presence of diabetes mellitus), a significant direct association only remained between TC and MI risk in men (HR: 2.71; 95%CI: 1.12-6.57; P-value< 0.05). CONCLUSION: In the present study, TC baseline level was significantly associated with the risk of MI among men.

High-density lipoprotein (HDL) function rather than level may better predict cardiovascular disease (CVD). However, the contribution of the impaired antioxidant function of HDL that is associated with increased HDL lipid peroxidation (HDLox) to the development of clinical CVD remains unclear. We have investigated the association between serum HDLox with incident CVD outcomes in Mashhad cohort. Three-hundred and thirty individuals who had a median follow-up period of 7 years were recruited as part of the cohort. The primary end point was cardiovascular event, including myocardial infarction, stable angina, unstable angina, or coronary revascularization. In both univariate/multivariate analyses adjusted for traditional CVD risk factors, HDLox was an independent risk factor for CVD (odds ratio, 1.62; 95% confidence interval, 1.41-1.86; p < 0.001). For every increase in HDLox by 0.1 unit, there was an increase in CVD risk by 1.62-fold. In an adjusted analysis, there was a >2.5-fold increase in cardiovascular risk in individuals with HDLox higher than cutoff point of 1.06 compared to those with lower scores, suggesting HDLox > 1.06 is related to the impaired HDL oxidant function and in turn exposed to elevated risk of CVD outcomes (hazard ratio, 2.72; 95% CI, 1.88-3.94). Higher HDLox is a surrogate measure of reduced HDL antioxidant function that positively associated with cardiovascular events in a population-based cohort.
RESUMO
Serum high-sensitivity C-reactive protein (hs-CRP) is predictive of coronary artery disease (CAD). The aim of this study was to examine the possible association of hs-CRP with presence and severity of CAD and traditional CAD risk factors. This case-control study was carried out on 2,346 individuals from September 2011 to May 2013. Of these 1,187 had evidence of coronary disease, and were subject to coronary angiography, and the remainder were healthy controls (n = 1,159). Characteristics were determined using standard laboratory techniques and serum Hs-CRP levels were estimated using enzyme-linked immunosorbent assay (ELISA) kits, and severity of CAD was assessed according to the score of obstruction in coronary artery. Serum hs-CRP levels were higher in those with severe coronary disease, who had stenosis ≥ 50% stenosis of at least one coronary artery (all p < 0.001 vs. individuals in healthy control), and correlated significantly with the score for coronary artery disease (all p < 0.01). After adjustment for conventional risk factors, regression analysis revealed that smoking habits, fasting blood glucose, total cholesterol, high-density lipoprotein, hs-CRP, blood pressure, anxiety, dietary intake of vitamin E, and cholesterol remained as independent determinants for angiographic severity of CAD. The area under the receiving operating characteristic (ROC) curve for serum hs-CRP was 0.869 (CI 95% 0.721-0.872, p < 0.001). The optimal values for the cut-off point was a serum hs-CRP of 2.78 mg/l (sensitivity 80.20%, specificity 85%) to predict severity of CAD. Increased serum hs-CRP levels are significantly associated with angiographic severity of CAD, suggesting its value as a biomarkers for predicting CAD.

BACKGROUND: Combination of dyslipidemic phenotypes, including elevated plasma levels of low-density lipoprotein cholesterol (LDL-C), elevated plasma triglycerides (TG), and decreased low-density lipoprotein cholesterol (HDL-C) concentrations, is important because of the association of individual phenotypes with increased risk of cardiovascular disease (CVD). We investigated the prevalence of combined dyslipidemias and their effects on CVD risk in an Iranian large population. METHOD: A total of 9847 individuals were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Anthropometric parameters and biochemical indices were measured in all of the subjects. Different types of combined dyslipidemias including high TG + low HDL-C, high TG + low HDL-C + high LDL-C, low HDL-C + high LDL-C, high TG + high LDL-C, and finally high TG + high LDL-C + low HDL-C were considered. Ten-year CVD risk was calculated using the QRISK2 risk algorithm and adjustments were made as suggested by the Joint British Societies' (JBS2). Logistic regression analyses were performed to determine the association between different combined dyslipidemias and categorical QRISK. RESULTS: A total of 3952 males and 5895 females were included in this current study. Among the included subjects, 83.4% had one form of dyslipidemia, and 16.6% subjects were not dyslipidemic. The mean age was 48.88 ± 7.9 and 47.02 ± 8.54 years for dyslipidemic and nondyslipidemic groups, respectively. The results showed that the frequency of dyslipidemia was 98%, 87.1%, and 90% in subjects with metabolic syndrome, CVD, and diabetes, respectively. Our results suggested that around 15.7% of study population were at 10 years CVD risk (high ≥20) and it was higher in men than women (P < .001). Moreover, risk of CVD was higher in TG↑ & HDL↓ & LDL↑ group than other groups. CONCLUSION: Prevalence of dyslipidemia was 83.4% among Iranian adults. The results showed that individuals with increased plasma TG and LDL-C, and low HDL-C levels had the highest 10 years CVD risk compared to other combined dyslipidemic phenotypes.

Cytokines play a key role in the pathogenesis of coronary artery disease (CAD). The aim of current study was to investigate the relationship between the serum concentrations of 12 cytokines with mortality and extent of CAD in individuals undergoing angiography and healthy controls. 342 CAD patients were recruited and divided into 2 groups: those with ≥50% occlusion in at least one coronary artery [Angiography (+)] or <50% obstruction in coronary arteries [Angiography (-)]. Also 120 healthy subjects were enrolled as control group. Lipid profile, fasting blood glucose, body mass index, and blood pressure were evaluated in all the subjects. An Evidence Investigator® was used for measuring 12 cytokines (IL-1α, IL-1ß, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, MCP-1, IFN-γ, EGF, VEGF) using sandwich chemiluminescent assays. Univariate analysis, multivariate regression models, ROC, and Kaplan-Meier survival curves were used for exploring the candidate markers in CAD patients. Serum level of IFN-γ, IL-4, MCP-1, EGF, IL-6, and IL-8 were markedly higher in angiogram-positive patients, while VEGF concentrations were significantly (P < 0.05) lower, compared to control group. ROC analysis for MCP-1 showed that a cut-off of 61.95 pg/mL had 91% sensitivity and 91% specificity for predicting CAD patients. Moreover, >2.16 pg/mL IL-6 had a > 94% sensitivity and 70% specificity in predicting 2 years mortality in the subjects with a serum MCP-1 > 61.95 pg/ mL, and patients having IL-6/MCP-1 combination had a shorter survival.Our findings demonstrate that CAD patients with serum MCP-1 and IL-6 levels of >61.95 and >2.16 pg/mL had a higher mortality with 94.1% sensitivity and 70.5% specificity for predicting mortality in CAD patients.

BACKGROUND: The prevalence of coronary artery disease (CAD) is increasing globally, supporting the need for the identification of novel biomarkers. Therefore in the present study, we have explored the association of SIL2A, SIL6R, STNFRI, STNFRII, and MMP9 in CAD patients. METHODS: Twenty one patients with angiographically defined CAD with more than 50% occlusion, at least, in one coronary artery and twenty healthy subjects (n=20) without the history of cardiovascular symptoms were enrolled. Demographic and biochemical analysis (e.g. Total Cholesterol (TC), Triglyceride (TG), and HDL-C) were measured in all the subjects. The level of cytokines receptor (SIL2A, SIL6R, SIL6R, STNFRI, STNFRII, and matrix metallopeptidase 9 (MMP9) were evaluated. RESULTS: Our results showed the higher level of MMP9 in patients group compared to the control subjects, while no significant differences were detected for other cytokines. In particular the level of MMP9 was significantly (P=.015) increased from 181.16 ng/mL (95%CI: 112.1-199.2) to 192.0 ng/mL (95%CI: 181.5-265.2). Moreover, the sensitivity and specificity of MMP9 were 95.45% and 45%, respectively, as detected by receiver operating characteristic (ROC) curves. CONCLUSION: We demonstrate the significant correlation of MMP-9 with CAD with sensitivity of 95.45%, suggesting its role as a biomarker in CAD patients. Further studies in larger population - preferably multicenter setting - are warranted to explore the functional role of this marker in coronary artery disease.
