Background and Purpose Cardioembolism is a postulated mechanism of embolic stroke of undetermined source (ESUS). We investigated endothelial glycocalyx, aortic elastic properties, oxidative stress, and their association with left atrial (LA) function in ESUS and healthy individuals. Methods In 90 ESUS patients (age 50.4 ± 13.2) and 90 controls with similar risk factors, we measured: (1) perfused boundary region (PBR) of the sublingual arterial microvessels (range 5–25 µm), a marker inversely rel...

Background Anakinra, an interleukin-1 receptor antagonist and tocilizumab, an interleukin-6 receptor blocker, are used for the treatment of rheumatoid arthritis. We investigated the differential effects of anakinra and tocilizumab on myocardial and vascular function in an atherosclerosis model of patients with rheumatoid arthritis.

Abstract Inotropes aim at increasing cardiac output by enhancing cardiac contractility. They constitute the third pharmacological pillar in the treatment of patients with decompensated heart failure, the other two being diuretics and vasodilators. Three classes of parenterally administered inotropes are currently indicated for decompensated heart failure, (i) the beta adrenergic agonists, including dopamine and dobutamine and also the catecholamines epinephrine and norepinephrine, (ii) the phosp...

Randomized clinical trials initially used heart failure (HF) patients with low left ventricular ejection fraction (LVEF) to select study populations with high risk to enhance statistical power. However, this use of LVEF in clinical trials has led to oversimplification of the scientific view of a complex syndrome. Descriptive terms such as 'HFrEF' (HF with reduced LVEF), 'HFpEF' (HF with preserved LVEF), and more recently 'HFmrEF' (HF with mid-range LVEF), assigned on arbitrary LVEF cut-off point...

Background: Poor glycaemic control affects myocardial function. We investigated changes in endothelial function and left ventricular (LV) myocardial deformation in poorly controlled type 2 diabetics before and after glycaemic control intensification. Methods: In 100 poorly-controlled diabetic patients (age: 51 ± 12 years), we measured at baseline and at 12 months after intensified glycaemic control: (a) Pulse wave velocity (PWV, Complior); (b) flow-mediated dilatation (FMD, %) of the brachial ar...

Cardiogenic shock (CS) is increasingly recognized in patients with malignancies, while cancer is independently associated with worse prognosis in CS. A number of conditions may lead to CS in cancer, including acute coronary syndromes, cardiomyopathy, takotsubo syndrome, myocarditis, pulmonary embolism, tamponade, and cardiac herniation. In these conditions, CS may be related to cancer itself or to cancer therapy, including surgery, chemotherapy, or radiotherapy. Given the significantly improved ...

Abstract Heart Failure (HF) is a global pandemic with rapidly increasing prevalence. In an attempt to maintain patients well being, the therapeutic interest has expanded to the vicious cycles that confer to HF mortality and morbidity and a number of comorbidities have been targeted. Iron deficiency represents a common comorbid condition that affects outcomes in HF. The treatment of iron deficiency is strongly supported by the cardiologic societies all over the world. Intravenous iron, primarily ...
