Hemoglobin loss method calculates blood loss during pancreaticoduodenectomy and predicts bleeding-related risk factors. World J Gastrointest Surg 2024; 16:419-428. [PMID: 38463360 PMCID: PMC10921204 DOI: 10.4240/wjgs.v16.i2.419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 12/26/2023] [Accepted: 01/19/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND The common clinical method to evaluate blood loss during pancreaticoduodenectomy (PD) is visual inspection, but most scholars believe that this method is extremely subjective and inaccurate. Currently, there is no accurate, objective method to evaluate the amount of blood loss in PD patients. AIM The hemoglobin (Hb) loss method was used to analyze the amount of blood loss during PD, which was compared with the blood loss estimated by traditional visual methods. The risk factors for bleeding were also predicted at the same time. METHODS We retrospectively analyzed the clinical data of 341 patients who underwent PD in Shandong Provincial Hospital from March 2017 to February 2019. According to different surgical methods, they were divided into an open PD (OPD) group and a laparoscopic PD (LPD) group. The differences and correlations between the intraoperative estimation of blood loss (IEBL) obtained by visual inspection and the intraoperative calculation of blood loss (ICBL) obtained using the Hb loss method were analyzed. ICBL, IEBL and perioperative calculation of blood loss (PCBL) were compared between the two groups, and single-factor regression analysis was performed. RESULTS There was no statistically significant difference in the preoperative general patient information between the two groups (P > 0.05). PD had an ICBL of 743.2 (393.0, 1173.1) mL and an IEBL of 100.0 (50.0, 300.0) mL (P < 0.001). There was also a certain correlation between the two (r = 0.312, P < 0.001). Single-factor analysis of ICBL showed that a history of diabetes [95% confidence interval (CI): 53.82-549.62; P = 0.017] was an independent risk factor for ICBL. In addition, the single-factor analysis of PCBL showed that body mass index (BMI) (95%CI: 0.62-76.75; P = 0.046) and preoperative total bilirubin > 200 μmol/L (95%CI: 7.09-644.26; P = 0.045) were independent risk factors for PCBL. The ICBLs of the LPD group and OPD group were 767.7 (435.4, 1249.0) mL and 663.8 (347.7, 1138.2) mL, respectively (P > 0.05). The IEBL of the LPD group 200.0 (50.0, 200.0) mL was slightly greater than that of the OPD group 100.0 (50.0, 300.0) mL (P > 0.05). PCBL was greater in the LPD group than the OPD group [1061.6 (612.3, 1632.3) mL vs 806.1 (375.9, 1347.6) mL] (P < 0.05). CONCLUSION The ICBL in patients who underwent PD was greater than the IEBL, but there is a certain correlation between the two. The Hb loss method can be used to evaluate intraoperative blood loss. A history of diabetes, preoperative bilirubin > 200 μmol/L and high BMI increase the patient's risk of bleeding.

Temporal trends in low-dose aspirin therapy for primary prevention of cardiovascular disease in European adults with and without diabetes. Eur J Prev Cardiol 2023; 30:1172-1181. [PMID: 36947152 DOI: 10.1093/eurjpc/zwad092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 03/10/2023] [Accepted: 03/20/2023] [Indexed: 03/23/2023]
Abstract
AIMS Aspirin therapy for primary prevention of cardiovascular disease (CVD) is controversial, and guideline recommendations have changed throughout the last decades. We report temporal trends in primary prevention aspirin use among persons with and without diabetes and describe characteristics of incident aspirin users. METHODS AND RESULTS Using Danish nationwide registries, we identified incident and prevalent aspirin users in a population of subjects ≥40 years without CVD eligible for primary preventive aspirin therapy from 2000 through 2020. Temporal trends in aspirin users with and without diabetes were assessed, as were CVD risk factors among incident users. A total of 522 680 individuals started aspirin therapy during the study period. The number of incident users peaked in 2002 (39 803 individuals, 1.78% of the eligible population) and was the lowest in 2019 (11 898 individuals, 0.49%), with similar trends for subjects with and without diabetes. The percentage of incident users with no CVD risk factors [diabetes, hypertension, hypercholesterolemia, or chronic obstructive pulmonary disease (a proxy for smoking)] decreased from 53.9% in 2000 to 30.9% in 2020. The temporal trends in prevalent aspirin users followed a unimodal curve, peaked at 7.7% in 2008, and was 3.3% in 2020. For subjects with diabetes, the peak was observed in 2009 at 38.5% decreasing to 17.1% in 2020. CONCLUSION Aspirin therapy for primary prevention of CVD has decreased over the last two decades. However, the drug remained used in individuals with and without diabetes, and a large proportion of individuals started on aspirin therapy had no CVD risk factors.

Platelet Glycoprotein-Ib (GPIb) May Serve as a Bridge between Type 2 Diabetes Mellitus (T2DM) and Atherosclerosis, Making It a Potential Target for Antiplatelet Agents in T2DM Patients. Life (Basel) 2023; 13:1473. [PMID: 37511848 PMCID: PMC10381765 DOI: 10.3390/life13071473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 06/23/2023] [Accepted: 06/26/2023] [Indexed: 07/30/2023] Open
Abstract
Type 2 diabetes mellitus (T2DM) is a persistent metabolic condition that contributes to the development of cardiovascular diseases. Numerous studies have provided evidence that individuals with T2DM are at a greater risk of developing cardiovascular diseases, typically two to four times more likely than those without T2DM, mainly due to an increased risk of atherosclerosis. The rupture of an atherosclerotic plaque leading to pathological thrombosis is commonly recognized as a significant factor in advancing cardiovascular diseases caused by TD2M, with platelets inducing the impact of plaque rupture in established atherosclerosis and predisposing to the primary expansion of atherosclerosis. Studies suggest that individuals with T2DM have platelets that display higher baseline activation and reactivity than those without the condition. The expression enhancement of several platelet receptors is known to regulate platelet activation signaling, including platelet glycoprotein-Ib (GPIb). Furthermore, the high expression of platelet GP1b has been reported to increase the risk of platelet adhesion, platelet-leucocyte interaction, and thrombo-inflammatory pathology. However, the study exploring the role of GP1b in promoting platelet activation-induced cardiovascular diseases in T2DM patients is still limited. Therefore, we summarize the important findings regarding pathophysiological continuity between T2DM, platelet GPIb, and atherosclerosis and highlight the potential therapy targeting GPIb as a novel antiplatelet agent for preventing further cardiovascular incidents in TD2M patients.

Duration of the diabetic state altered platelet indices from baseline values in a streptozotocin-induced rat model for type 1 diabetes mellitus. Vet Clin Pathol 2023; 52:236-242. [PMID: 36973508 DOI: 10.1111/vcp.13229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 11/08/2022] [Accepted: 12/07/2022] [Indexed: 03/29/2023]
Abstract
BACKGROUND Changes in platelet indices in naturally occurring type I diabetes mellitus (T1DM) have been described in several studies. In this study, platelet indices such as platelet count (PLT), plateletcrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), and MPV to PLT ratio were investigated according to diabetic duration after streptozotocin (STZ)-induced T1DM, as well as for their correlation with glucose. METHODS Forty healthy adult Wistar rats were randomly assigned to four experimental groups of ten (5 rats of each sex), including the control group, the 7, 14, and 28 days diabetic groups (D7, D14, and D28, respectively). RESULTS In diabetic groups, plasma glucose was significantly higher than in control (P < 0.01). D7, D14, and D28 groups presented significantly lower PLT than the control (P < 0. 01). A significant decrease in PCT was observed in D14 and D28 females (P < 0.05). Mean platelet volume was significantly higher in the D28 group than in to control. D28 females also showed a significant difference in PLT, MPV, and the MPV-to-PLT ratio compared with D7 females (P < 0.05). A comparison between D28 females and males showed a significant difference in PDW (P < 0.05). Both females and males showed a significant correlation between glucose and PLT, PCT, MPV, and the MPV-to-PLT ratio. CONCLUSIONS Platelet indices change significantly with the duration of diabetes compared with the baseline values, and female and male rats did not have significant differences in platelet indices in any period except the 28 days.

Abstract
OBJECTIVE The studies evaluating cases with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) in the adult population reported hyperreactive platelets and increased activation of prothrombotic factors, resulting in an increased risk of thrombosis. The aim of this study was to evaluate the effects of poor glycemic control and the duration of diabetes on platelet parameters in pediatric population. METHODS The study included 366 children, out of which 144 (39.3%) were included in the T1DM group and 222 (60.6%) in the healthy control group. The platelet count, mean platelet volume (MPV), platelet distribution width and plateletcrit values were recorded. The children with T1DM were divided into three groups as per their glycated hemoglobin (HbA1c) levels, good (<7.5%), moderate (7.5-9%) and poor metabolic control (>9%). RESULTS No significant difference in the MPV level between the T1DM (7.41 ± 1.49 fl) and control (7.15 ± 1.23 fl) groups was observed. However, the MPV levels were significantly higher in the poor glycemic control group than in the healthy control group (p = 0.026). Furthermore, as the duration of diabetes and HbA1c levels increased, the MPV levels also increased (p < 0.001, p = 0.441). CONCLUSION This study suggested as the duration of diabetes and HbA1c levels increased, the MPV levels also increases. Evaluation of hematological parameters can be a cheap and useful method in the evaluation of diabetes regulation in patients with diabetes.

Abstract
We investigated the platelet count (PLT), mean platelet volume (MPV), and plateletcrit (PCT) in dogs with type 1 diabetes mellitus (DM) compared to healthy controls, and their association with the major fraction of glycated hemoglobin (HbA1c). Blood samples from 33 clinically healthy dogs and 14 newly diagnosed diabetic dogs were included. CBCs were performed with the Advia 120; HbA1c was determined using a validated assay (Capillarys 2 flex-piercing; Sebia). Median [range] PLT and PCT were significantly higher (p = 0.040 and p = 0.010, respectively) in diabetic dogs (434 [176-987] × 109/L and 0.60 [0.26-1.22]%, respectively) compared to healthy dogs (297 [223-671] × 109/L and 0.35 [0.24-0.87]%, respectively]. Thrombocytosis was observed in 6 of 14 (43%) diabetic dogs. The median MPV was not significantly different (p = 0.114) between the diabetic (13.6 fL, 10.1-22.6 fL) and healthy dogs (11.9 fL, 8.6-19.1 fL). A significant, albeit weak, correlation was detected between HbA1c and PLT (rho = 0.298, p = 0.042) and PCT (rho = 0.340, p = 0.019), but no significant correlation was found with MPV (rho = 0.199, p = 0.180). Canine DM was associated with increased PLT and PCT, which was correlated with glycemic status. Our findings suggest dysregulated megakaryopoiesis in diabetic dogs, but this should be confirmed by large-scale studies, and the clinical implications should be investigated.

Association between central non-dipping pattern and platelet morphology in adults with type 1 diabetes without cardiovascular disease: a cross-sectional study. Sci Rep 2021; 11:15416. [PMID: 34326364 PMCID: PMC8322100 DOI: 10.1038/s41598-021-94414-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 06/14/2021] [Indexed: 11/15/2022] Open
Abstract
The non-dipping pattern is nighttime systolic blood pressure (SBP) fall of less than 10%. Several studies showed that the non-dipping pattern, increased mean platelet volume (MPV), and platelet distribution width (PDW) are associated with elevated cardiovascular risk. Hypertensives with the non-dipping pattern have higher MPV than the dippers but this relationship was never investigated among people with type 1 diabetes mellitus (T1DM). This study aimed to investigate the association between the central dipping pattern and platelet morphology in T1DM subjects. We measured the central and brachial blood pressure with a validated non-invasive brachial oscillometric device—Arteriograph 24—during twenty-four-hour analysis in T1DM subjects without diagnosed hypertension. The group was divided based on the central dipping pattern for the dippers and the non-dippers. From a total of 62 subjects (32 males) aged 30.1 (25.7–37) years with T1DM duration 15.0 (9.0–20) years, 36 were non-dippers. The non-dipper group had significantly higher MPV (MPV (10.8 [10.3–11.5] vs 10.4 [10.0–10.7] fl; p = 0.041) and PDW (13.2 [11.7–14.9] vs 12.3 [11.7–12.8] fl; p = 0.029) than dipper group. Multivariable logistic regression revealed that MPV (OR 3.74; 95% CI 1.48–9.45; p = 0.005) and PDW (OR 1.91; 95% CI 1.22–3.00; p = 0.005) were positively associated with central non-dipping pattern adjusting for age, sex, smoking status, daily insulin intake, and height. MPV and PDW are positively associated with the central non-dipping pattern among people with T1DM.

Abstract
Background Altered mean platelet volume (MPV) and plasma albumin has been reported in type 2 diabetes (T2D). MPV is suggested to predict cardiovascular risk but there is a lack of evidence for associations between MPV and platelet adhesion. Plasma albumin and magnesium are other factors reported to influence thrombotic risk. The objectives of this study were to assess the association between platelet adhesion and plasma factors with a potential role to affect platelet activation. Methods Blood was collected from 60 T2D patients and 60 healthy controls. Platelet adhesion to different protein surfaces induced by various soluble activators were measured in microplates. MPV, albumin and magnesium were analysed together with additional routine tests. Results Despite normal levels, plasma albumin significantly correlated with adhesion of T2D platelets but not with controls. There was a significant association between MPV and platelet adhesion in both groups, but association was smaller in T2D. Levels of glucose, HbA1c or magnesium did not correlate with platelet adhesion. Conclusions Plasma albumin was associated with platelet adhesion in T2D suggesting that albumin may be a factor to consider upon cardiovascular risk assessment. MPV was more associated with the level of platelet adhesion in healthy individuals than in well-controlled T2D patients.

Abstract
In patients with diabetes, metabolic disorders disturb the physiological balance of coagulation and fibrinolysis, leading to a prothrombotic state characterized by platelet hypersensitivity, coagulation disorders and hypofibrinolysis. Hyperglycemia and insulin resistance cause changes in platelet number and activation, as well as qualitative and/or quantitative modifications of coagulatory and fibrinolytic factors, resulting in the formation of fibrinolysis-resistant clots in patients with diabetes. Other coexisting factors like hypoglycemia, obesity and dyslipidemia also contribute to coagulation disorders in patients with diabetes. Management of the prothrombotic state includes antiplatelet and anticoagulation therapies for diabetes patients with either a history of cardiovascular disease or prone to a higher risk of thrombus generation, but current guidelines lack recommendations on the optimal antithrombotic treatment for these patients. Metabolic optimizations like glucose control, lipid-lowering, and weight loss also improve coagulation disorders of diabetes patients. Intriguing, glucose-lowering drugs, especially cardiovascular beneficial agents, such as glucagon-like peptide-1 receptor agonists and sodium glucose co-transporter inhibitors, have been shown to exert direct anticoagulation effects in patients with diabetes. This review focuses on the most recent progress in the development and management of diabetes related prothrombotic state.

Abstract
BACKGROUND Diabetes mellitus, largely type 2, affects nearly 10% of the global adult population according to the World Health Organization. Diabetes is an independent risk factor for atherosclerotic cardiovascular diseases, including coronary artery disease. Diabetes patients experience a two to three-fold increased incidence of coronary artery disease, despite improved metabolic control and management of other cardiovascular risk factors. DISCUSSION Platelet abnormalities and activation as well as reduced antiplatelet drug responsiveness characterise diabetes mellitus. Mechanisms linking diabetes to platelet and vascular abnormalities, atherogenesis and atherosclerotic cardiovascular disease are still only partially known, highlighting the unique complexity of the pro-atherogenic clinical scenario and its treatment. Consistently, a higher residual cardiovascular risk characterises patients with diabetes compared with those without, in spite of improved antiplatelet and antithrombotic treatment combinations. Randomised clinical trials aimed at optimising antiplatelet treatment specifically in patients with diabetes are lacking, both in acute and chronic coronary artery disease settings. Thus, patients with diabetes are treated with regimens validated in studies including only variable proportions of diabetes patients. Myocardial revascularisation appears to confer a comparable relative benefit between diabetes patients and patients without diabetes, and generally coronary artery bypass grafting has a better outcome in diabetes mellitus versus peripheral coronary intervention. New glucose-lowering drugs have been shown to reduce the incidence of major cardiovascular events in secondary prevention. Type 1 diabetes mellitus remains less explored than type 2 in this context. CONCLUSION Diabetes-tailored antithrombotic strategies in acute and chronic coronary artery disease remain an unmet clinical need, requiring ad-hoc trials and precision pharmacological strategies.

Abstract
PURPOSE OF REVIEW To critically review the literature describing links between mean platelet volume (MPV) and cardiovascular disease (CVD). We will focus on coronary artery disease (CAD). The MPV is measured routinely as part of a routine blood count. RECENT FINDINGS There is accumulating evidence showing that the MPV may predict CVD, as well as outcomes in patients with CAD. There is also evidence linking MPV and comorbidities (e.g. diabetes mellitus and impaired glycaemic control) that are expected in patients with CAD. The effect on MPV of drugs commonly used to treat CAD has not been clarified, but there is some evidence that they may exert a beneficial effect on the MPV. More specifically, the MPV may predict the effect of antiplatelet drugs (e.g. clopidogrel). There is also evidence relating MPV to stroke, atrial fibrillation, coronary artery ectasia and periprocedural outcomes after percutaneous coronary intervention (PCI). SUMMARY Measuring the MPV may prove useful in CVD risk assessment in patients with established CAD or at risk of developing CAD. Overall, there is evidence pointing to the role of MPV as a contributor rather than simple marker of CVD.

Abstract
Although the improved control of hyperglycaemia and other cardiovascular risk factors was associated with a parallel decline of atherosclerotic cardiovascular disease (ASCVD) and death in both type 1 (T1) and type 2 (T2) diabetes mellitus (DM), the burden of death and hospitalization for ASCVD remains significantly higher by about 2-fold versus the matched non-DM population. Life style interventions, such as physical activity and healthy diet, and drugs, such as statins and low-dose aspirin, may have beneficial effects by targeting one or multiple pathways responsible for accelerated atherosclerosis and its thrombotic complications. The debate on the benefit-risk balance of primary cardiovascular prevention with aspirin has been especially vivacious over the past two years, following the publication of three large randomized, placebo-controlled, primary prevention trials in different settings, spanning from healthy elderly to DM subjects. The aim of this review is to discuss the pathophysiological, pharmacological and clinical evidence supporting the appropriate use of low-dose aspirin in DM, within the context of the current multifactorial approach to primary cardiovascular prevention.

Abstract
Diabetes (both type-1 and type-2) affects millions of individuals worldwide. A major cause of death for individuals with diabetes is cardiovascular diseases, in part since both types of diabetes lead to physiological changes that affect haemostasis. Those changes include altered concentrations of coagulatory proteins, hyper-activation of platelets, changes in metal ion homeostasis, alterations in lipid metabolism (leading to lipotoxicity in the heart and atherosclerosis), the presence of pro-coagulatory microparticles and endothelial dysfunction. In this review, we explore the different mechanisms by which diabetes leads to an increased risk of developing coagulatory disorders and how this differs between type-1 and type-2 diabetes.

Abstract
Platelet (PLT) hyperactivity is a key factor which contributes to cardiovascular complications in patients with type 2 diabetes mellitus even in preclinical stages of disease. To the best of our knowledge, there is limited researches in this regard among patients with type 1 diabetes. The aim of this study was to evaluate hematologic indices indicating PLT activity in children with type 1 diabetes. This was a case-control study which was conducted on 166 inpatients in 17 Shahrivar children hospital, Rasht, Iran during April 2016 to April 2017. Cases and controls were 83 children with type 1 diabetes mellitus and 83 children hospitalized for thorough assessment of short stature, respectively. Groups were matched for age and sex. Demographic characteristics and hematologic variables were assessed. The Shapiro-Wilk test was used to determine the normality of the distribution. Results for continuous and categorical variables were demonstrated as mean±SD and number and percent, respectively. Continuous variables without normal distribution were demonstrated as median (interquartile range). The χ/Fisher's exact test was used to compare categorical variables. The normal and non-normal distributed quantitative variables were respectively assessed by independent T-test or Mann-Whitney U test. P-value <0.05 noted statistical significance. The median (interquartile range) age of all children was 10 (6 to 13) years old. Thirty-five (42.2) of patients with diabetes and 35 (42.2) of control group were male individuals. There were positive correlation between age (r=0.370; P=0.001), hemoglobin (r=0.278; P=0.009), blood sugar (r=0.243; P=0.027), PLT distribution width (r=0.229; P=0.038), plateletcrit (PCT) (r=0.290; P=0.008), PLT to lymphocyte ratio (r=0.230; P=0.037) and glycosylated hemoglobin in children with diabetes. The cut-off point of PCT was 0.19 (sensitivity=87.8%, specificity=66.7%). Only increased PCT (>0.19) was related with poor metabolic control and can put the patients to the risk of future cardiovascular events. The authors recommend considering multiple PLT parameters, and not just one of them, and even designing a scoring system in terms of PLT parameters for type 1 diabetes mellitus management programs.

Platelet number is positively and independently associated with glycated hemoglobin in non-diabetic overweight and obese subjects. Nutr Metab Cardiovasc Dis 2019; 29:254-259. [PMID: 30738641 DOI: 10.1016/j.numecd.2018.12.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2018] [Revised: 12/05/2018] [Accepted: 12/28/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND AIMS A significant increase in platelet count may be a risk factor for atherosclerotic cardiovascular disease. This study investigates the association between platelet number and glucose metabolism, evaluated by glycated hemoglobin (HbA1c) levels, in a apparently healthy population represented by overweight and obese subjects with normal glucose and HbA1c levels. METHODS AND RESULTS As many as 240 subjects, 177 women and 63 men, aged 18-70 years, were enrolled. Body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure levels, platelet count and fasting blood glucose, insulin, insulin resistance, HbA1c, uric acid, triglyceride, total cholesterol, high and low density lipoprotein cholesterol concentrations were evaluated. Concerning the univariate correlation analyses between platelets number and all other variables, platelet count was significantly (and positively) correlated only with HbA1c (P < 0.05) and female sex (P < 0.01). HbA1c (P < 0.05), female sex (P < 0.001), and diastolic blood pressure (P < 0.01), positively, and age (P < 0.05) and systolic blood pressure (P < 0.05), negatively, were significantly and independently associated to platelet count in a final multiple regression analysis. CONCLUSION This is the first study showing a strong positive and independent relationship between HbA1c and platelet number in non-diabetic overweight and obese subjects.

Abstract
Obesity and the metabolic syndrome (MS) are two of the pressing healthcare problems of our time. The MS is defined as increased abdominal obesity in concert with elevated fasting glucose levels, insulin resistance, elevated blood pressure, and plasma lipids. It is a key risk factor for type 2 diabetes mellitus (T2DM) and for cardiovascular complications and mortality. Here, we review work demonstrating that various aspects of coagulation and hemostasis, as well as vascular reactivity and function, become impaired progressively during chronic ingestion of a western diet, but also acutely after meals. We outline that both T2DM and cardiovascular disease should be viewed as inflammatory diseases and describe that chronic overload of free fatty acids and glucose can trigger inflammatory pathways directly or via increased production of ROS. We propose that since endothelial stress and increases in platelet activity precede inflammation and overt symptoms of the MS, they are likely the first hit. This suggests that endothelial activation and insulin resistance are probably causative in the observed chronic low-level metabolic inflammation, and thus both metabolic and cardiovascular complications linked to consumption of a western diet.
