OBJECTIVE: Speckle tracking echocardiography (STE) enables global and regional evaluation of the left ventricle (LV); therefore, it is the most useful method for detecting subclinical dysfunction in patients exposed to cardiotoxic agents. A novel technique triplane (3P) echocardiography also allows single beat assessment of LV global longitudinal strain values. We firstly aimed to demonstrate both two-dimensional (2D)- and 3PSTE-derived LV global longitudinal strain measurements in children after anthracycline exposure...

OBJECTIVE: Pedal (inframalleolar) bypass is a long-standing therapy for tibial arterial disease in patients with ischemic tissue loss. Endovascular tibial intervention is an appealing alternative with lower risks of perioperative mortality or complications. Our objective was to compare the effectiveness of these two treatment modalities with respect to patency and limb-related clinical outcomes. METHODS: We performed a retrospective chart review of patients presenting between 2006 and 2013 with ischemic foot wounds and infrapopliteal arterial disease who underwent a revascularization procedure (either open surgical bypass to an inframalleolar target or endovascular tibial intervention)...

Previous studies have demonstrated that oxymatrine may inhibit ventricular remodeling and serves an important role in the treatment of cardiovascular disease. The present study investigated whether oxymatrine treatment protects against the effects of cardiopulmonary resuscitation (CPR) via regulation of the transforming growth factor‑β1 (TGF‑β1)/mothers against decapentaplegic (Smad) signaling pathway. A CPR model was established in Sprague‑Dawley (SD) rats by asphyxiation, and rats were subsequently anaesthetized by intraperitoneal injection of chloral hydrate...

BACKGROUND: Warfarin has a long history of use to reduce the risk of stroke in patients with atrial fibrillation (AF), but it requires frequent laboratory monitoring to maintain international normalized ratio levels in the therapeutic range. Dabigatran, a novel oral anticoagulant (OAC), has demonstrated efficacy in reducing the risk of stroke and systemic embolism and does not require laboratory monitoring. OBJECTIVE: To compare health care resource utilization (HCRU) and costs of OAC-naive patients newly diagnosed with nonvalvular atrial fibrillation (NVAF), using dabigatran or warfarin...

Both patients with non-ischaemic systolic heart failure and patients with type 2 diabetes (T2DM) often have reduced myocardial blood flow without significant coronary atherosclerosis. However, the mechanisms are not fully understood. The aim of this study was to investigate whether perfusion is reduced additionally when the 2 are combined. In a cross-sectional study, we scanned patients with non-ischaemic systolic heart failure with and without T2DM using Rubidium-82 positron emission tomography/computed tomography at rest and adenosine-induced stress, thereby obtaining the myocardial flow reserve (myocardial flow reserve (MFR) = stress flow/rest flow) as a measure of the myocardial vasomotor function; 28 patients with T2DM and 123 without T2DM were included...
