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...

Mesenchymal stem cells (MSCs) are multipotent stem cells that reside in various organs. They have the capacity to differentiate into various cell types, including cardiomyocytes, vascular endothelial cells, and vascular smooth muscle cells. Among the various MSCs, bone marrow-derived MSCs (BMMSCs) have been widely used for treating acute myocardial infarction (AMI) and ischemic heart failure (IHF) in preclinical and clinical studies. Although the beneficial effects of BMMSCs in treating AMI and IHF were originally attributed to their capacity to differentiate into cardiac cell types, recent evidence suggests that the differentiation capacity of BMMSCs appears to be minimal and that BMMSCs exert cardioprotective effects by secreting paracrine factors...

Heart transplantation (HTx) is a method of treatment for patients with end-stage heart failure with severe symptoms despite complex therapy. Post-transplant difficulties include acute rejection and infectious complications, which are the most common reason of morbidity and mortality in the first year after heart transplant. It requires the patient to remain on immunosuppressive medication to avoid the possibility of graft rejection. Therefore the range of infection is much larger. The diagnosis and treatment of viral, bacterial and fungal infections is often difficult...

Background -Clinical trials of bone marrow cell (BMC)-based therapies after acute myocardial infarction (MI) have produced mostly neutral results. Treatment with specific BMC-derived secreted proteins may provide an alternative biologic approach to improving tissue repair and heart function after MI. We recently performed a bioinformatic secretome analysis in BMCs from patients with acute MI and discovered a poorly characterized secreted protein, endoplasmic reticulum membrane protein complex subunit 10 (EMC10), showing activity in an angiogenic screen...

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...

There have been multiple reports of allergic reactions associated with acute coronary syndromes. This has been classically described as Kounis syndrome. We present an unusual case of 70-year-old male with multiple prior hypersensitivity reactions and history of coronary artery bypass grafting who presented recurrent episode of severe angioedema and anaphylaxis. He responded to epinephrine but subsequently developed a non-ST elevation myocardial infarction with worsening heart failure. Our case is unique in that, unlike classic Kounis syndrome, the acute coronary event in this case did not present concurrently with the allergic reaction; rather it took nearly 48 hours to present...

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...

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported...
