Biologically active epoxyeicosatrienoic acid (EET) regioisomers are synthesized from arachidonic acid by cytochrome P450 epoxygenases of endothelial, myocardial, and renal tubular cells. EETs relax vascular smooth muscle and decrease inflammatory cell adhesion and cytokine release. Renal EETs promote sodium excretion and vasodilation to decrease hypertension. Cardiac EETs reduce infarct size after ischemia-reperfusion injury and decrease fibrosis and inflammation in heart failure. In diabetes, EETs improve insulin sensitivity, increase glucose tolerance, and reduce the renal injury...

Diabetic subjects are at risk of developing cardiovascular disease, which accounts for 60-80% of diabetes-related mortality. Atherosclerosis is still considered as a leading cause of heart failure in diabetic patients, but it could also be an intrinsic and long-term effect of contractile cardiac cells malfunction, known as diabetic cardiomyopathy (DCM). Pathologically, this cardiac dysfunction is manifested by inflammation, apoptosis, fibrosis, hypertrophy and altered cardiomyocytes metabolism. However, the underlying molecular mechanisms of DCM pathophysiology are not clearly understood...

Type 2 diabetes mellitus (T2DM) is a major risk factor for heart disease. Mortality rates following myocardial infarction (MI) are significantly increased in T2DM patients due to dysfunctional left ventricle (LV). However, molecular pathways underlying accelerated post-MI heart failure (HF) in T2DM remain unclear. We investigated the underlying mechanisms by inducing MI in a well-established model of T2DM and control mice. Cardiac imaging revealed a significantly decreased global LV ejection fraction (EF) in parallel with increased mortality post-MI in T2DM mice compared to controls...

Advanced glycation end products (AGE) have been implicated in diabetes associated complications. They have been suggested as potential mediators in the progression of diabetic heart failure and as a potential target for treatment. Brunvand et al. now provided evidence in that the suggested causal relationship between AGE and diastolic myocardial dysfunction cannot be confirmed in children with type 1 diabetes. The early signs of diastolic myocardial impairment were associated with higher BMI, but not with HbA1c levels...

Cardiovascular diseases account for the major cause of morbidity and mortality among individuals with diabetes. The diabetic cardiomyopathy (DCM) is a type of diabetic cardiovascular disease, which further directs to the heart failure. The researchers found that diabetes induced cardiac fibrosis plays a vital role in several of the pathological changes that associated with DCM, causing left ventricular hypertrophy (LVH), diastolic dysfunction and systolic dysfunction. However, the mechanisms involved in the pathogenesis of DCM are still elusive...

Mitochondria are very versatile organelles in continuous fusion and fission processes in response to various cellular signals. Mitochondrial dynamics, including mitochondrial fission/fusion, movements and turnover, are essential for the mitochondrial network quality control. Alterations in mitochondrial dynamics can cause neuropathies such as Charcot-Marie-Tooth disease in which mitochondrial fusion and transport are impaired, or dominant optic atrophy which is caused by a reduced mitochondrial fusion. On the other hand, mitochondrial dysfunction in primary mitochondrial diseases promotes reactive oxygen species production that impairs its own function and dynamics, causing a continuous vicious cycle that aggravates the pathological phenotype...

BACKGROUND: Elevated B-type natriuretic peptide (BNP) is a hallmark in heart failure (HF). Diabetic patients with chronic HF seem to have higher BNP than nondiabetics. We studied, in acute HF, if BNP levels are different between diabetics and nondiabetics. METHODS: From a prospectively recruited population of acute HF patients, we selected a convenience sample. In pair-matched analysis, each diabetic patient was matched with a nondiabetic of the same age (±1 year), gender, and according to left ventricular systolic dysfunction...

INTRODUCTION: In our ageing society, we are at the merge of an expected epidemic of atrial fibrillation (AF). AF management requires an integrated approach, including rate or rhythm control, stroke prevention with anticoagulation and treatment of comorbidities such as heart failure or type 2 diabetes. As such, primary care seems to be the logical healthcare setting for the chronic management of patients with AF. However, primary care has not yet played a dominant role in AF management, which has been in fact more fragmented between different healthcare providers...

BACKGROUND: Patients with acute leukemia (AL) have a higher rate of congestive heart failure than patients with other cancers. AL may predispose to cardiac dysfunction before chemotherapy because of high cytokine release or direct leukemic myocardial infiltration. The aims of this study were to evaluate whether AL is associated with abnormalities of myocardial structure and function before chemotherapy and to identify possible risk factors associated with these myocardial changes. METHODS: Using an echocardiographic database, 76 patients with AL and 76 patients without cancer matched for age, gender, hypertension, and the presence of diabetes were retrospectively selected...

BACKGROUND: Although cancer treatment considerably affects cardiovascular health, little is known about how cancer patients are treated for an acute myocardial infarction. We aimed to investigate whether acute myocardial infarction patients with a history of cancer received the same guideline recommended treatment as those acute myocardial infarction patients without and whether they differ with respect to inhospital outcome. METHODS: All patients with ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction, enrolled between 2002 and mid-2015 in the acute myocardial infarction in Switzerland (AMIS Plus) registry with comorbidity data based on the Charlson comorbidity index were analysed...

Diabetic ketoacidosis (DKA) is a critical complication of type 1 diabetes associated with water and electrolyte disorders. Here, we report a case of DKA with extreme hyperkalemia (9.0 mEq/L) in a patient with type 1 diabetes on hemodialysis. He had a left frontal cerebral infarction resulting in inability to manage his continuous subcutaneous insulin infusion pump. Electrocardiography showed typical changes of hyperkalemia, including absent P waves, prolonged QRS interval and tented T waves. There was no evidence of total body water deficit...

Objective Post-stroke cognitive impairment often afflicts stroke survivors and is a major obstacle both for cognitive and physical rehabilitation. Stroke risk scores ["Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, Stroke" (CHADS2) and "CHADS2 + creatinine clearance <60 mL/min" (R2CHADS2)] are used to assess the future risk of cardioembolic stroke in patients with atrial fibrillation (AF). However, congestive heart failure, hypertension, aging, diabetes mellitus, stroke, and renal dysfunction are also risk factors for cognitive impairment...

Purpose The use of anthracycline chemotherapy is associated with heart failure (HF) among survivors of non-Hodgkin lymphoma (NHL). We aimed to understand the contribution of preexisting cardiovascular risk factors to HF risk among NHL survivors. Methods Using Danish registries, we identified adults diagnosed with aggressive NHL from 2000 to 2010 and sex- and age-matched general-population controls. We assessed HF from 9 months after diagnosis through 2012. We used Cox regression analysis to assess differences in risk for HF between survivors and general population controls...

BACKGROUND: The effect of the α-glucosidase inhibitor acarbose on cardiovascular outcomes in patients with coronary heart disease and impaired glucose tolerance is unknown. We aimed to assess whether acarbose could reduce the frequency of cardiovascular events in Chinese patients with established coronary heart disease and impaired glucose tolerance, and whether the incidence of type 2 diabetes could be reduced. METHODS: The Acarbose Cardiovascular Evaluation (ACE) trial was a randomised, double-blind, placebo-controlled, phase 4 trial, with patients recruited from 176 hospital outpatient clinics in China...

BACKGROUND: The best treatment option for patients with type 2 diabetes in whom treatment with metformin alone fails to achieve adequate glycaemic control is debated. We aimed to compare the long-term effects of pioglitazone versus sulfonylureas, given in addition to metformin, on cardiovascular events in patients with type 2 diabetes. METHODS: TOSCA.IT was a multicentre, randomised, pragmatic clinical trial, in which patients aged 50-75 years with type 2 diabetes inadequately controlled with metformin monotherapy (2-3 g per day) were recruited from 57 diabetes clinics in Italy...
