Relationship between early diastolic strain rate imaging and left ventricular geometric patterns in hypertensive patients
Springer Science and Business Media LLC - Tập 23 - Trang 271-278 - 2008
Hypertension is an important contributor to different left ventricular (LV) geometric patterns with resultant myocardial dysfunction. Strain rate image (SRI) has been suggested as a useful tool for the evaluation of myocardial function. The aim of this study was to assess whether SRI correlates with LV geometric patterns in hypertensive subjects. Fifty-one hypertensive subjects and 21 healthy cont...... hiện toàn bộ
The prognostic significance of a fragmented QRS complex after primary percutaneous coronary intervention
Springer Science and Business Media LLC - Tập 27 - Trang 20-28 - 2011
Fragmented QRS (fQRS) may occur due to non-homogeneous activation of ischemic ventricles. We want to investigate the prognostic significance of a fQRS complex in a patient who had undergone primary percutaneous coronary intervention (PCI). Eighty-five patients with no history of coronary artery disease who underwent primary PCI were included in the study. Of these patients, 34 who were found to ha...... hiện toàn bộ
Advanced atrioventricular block induced by obstructive sleep apnea before oxygen desaturation
Springer Science and Business Media LLC - - 2009
We report a patient with transient advanced atrioventricular (AV) block induced by obstructive sleep apnea (OSA). This 54-year-old man was diagnosed as having severe OSA and AV block with ventricular asystole for more than 6 s during overnight polysomnography, which occurred just from the onset of OSA before oxygen desaturation had occurred. An electrophysiological study revealed normal AV conduct...... hiện toàn bộ
Optimal therapeutic range for oral anticoagulants in Japanese patients with prosthetic heart valves: a preliminary report from a single institution using conversion from thrombotest to PT-INR
Springer Science and Business Media LLC - - 2000
The thrombotest (TT) technique has been widely used in Japan for monitoring oral anticoagulant therapy (OAT). The therapeutic range was originally recommended to be 10%–25%. However, the International Committee for Standardization in Hematology/International Committee on Thrombosis and Hemostasis (ICSH/ICTH) recommended using the international normalized ratio of prothrombin time (PT-INR) for mon...... hiện toàn bộ
Acute myocarditis with autoimmune features: one-year follow-up with CMR
Springer Science and Business Media LLC - Tập 37 - Trang 291-299 - 2021
In this prospective study on patients with acute myocarditis (AM), we aimed to describe the new concept of AMAF (AM with autoimmune features) similar to the previously described interstitial pneumonia with autoimmune features (IPAF). IPAF has recently emerged as a new entity, and IPAF patients appear to have fewer episodes of exacerbation and better survival than patients with idiopathic pulmonary...... hiện toàn bộ
Acute effects of amiodarone on membrane properties, refractoriness, and conduction in guinea pig papillary muscles
Springer Science and Business Media LLC - Tập 10 - Trang 78-86 - 1995
Amiodarone has potent and complex antiarrhythmic effects associated with a rare incidence of proarrhythmia. For a comprehensive understanding of its antiarrhythmic mechanisms in the same preparations, amiodarone (50 µM) was employed as it would be in the clinical setting and applied to guinea pig papillary muscles impaled by microelectrodes, paced at different rates, and superfused with various co...... hiện toàn bộ
Absent pulmonary valve syndrome with ascending aortic aneurysm
Springer Science and Business Media LLC - Tập 25 - Trang 569-572 - 2010
Absent pulmonary valve syndrome is rare. We report the case of a child with absent pulmonary valve syndrome noted after birth. Progressive dilatation of the main pulmonary artery and ascending aorta were noted by echocardiography and confirmed by heart computed tomography. He underwent ascending aorta graft replacement and pulmonary artery reduction angioplasty at the age of 6. Good outcome was ac...... hiện toàn bộ
Flow cytometric characterization of the saphenous veins endothelial cells in patients with chronic venous disease and in patients undergoing bypass surgery: an exploratory study
Springer Science and Business Media LLC - Tập 35 - Trang 1-13 - 2019
Recent findings have suggested that the primary factors for development of chronic venous disease (CVD), which commonly manifests as varicose veins (VV), are due to structural and biochemical modifications of the vessel wall. The aim of this exploratory study was to characterize by flow cytometry the endothelial cells (EC) mechanically extracted from the varicose saphenous veins (VSV) segments of ...... hiện toàn bộ
Inflammatory profile in subcutaneous and epicardial adipose tissue in men with and without diabetes
Springer Science and Business Media LLC - Tập 29 - Trang 42-48 - 2013
In recent years, evidence has emerged indicating that insulin resistance and diabetes mellitus type 2 are associated with inflammation of adipose tissue (AT). Interest has been focused on epicardial AT (EAT) because of its possible involvement with atherosclerosis and cardiovascular diseases. The aim of this study was to characterize adipocyte size and inflammatory profile in subcutaneous (SAT) an...... hiện toàn bộ
Disturbances of flow through transparent dog aortic arch
Springer Science and Business Media LLC - Tập 1 - Trang 24-28 - 1985
The present study was carried out to determine the hydrodynamic structure of flow in an aortic arch and to correlate the findings with the possible involvement of fluid dynamics in atherogenesis and thrombogenesis. Each aorta was made transparent under a transmural pressure of 100 mmHg to maintain its in vivo configuration. Methyl salicylate with a kinematic viscosity of 2.6 cSt was substituted fo...... hiện toàn bộ
