the clinical and economic importance of heart failure is widely recognized.   the incidence of heart failure is on the increase, particularly with the aging of the population around the world.   it is time for a paradigm shift in heart failure management. alternative non-pharmacological strategies to remodel the failing ventricle will shape a major portion of heart failure therapy in the decade...

background: primary percutaneous coronary intervention (primary pci) is the method of choice in establishing reperfusion in acute myocardial infarction (ami) patients. the aim of this study was to determine the success rate of primary pci in a university medical center in iran with a view to promoting it as a first-line therapy in patients with ami, especially in centers with established cathet...

background: we compared the outcomes in patients with a low ejection fraction (ef) and multivessel coronary artery disease (cad) who either underwent coronary artery bypass grafting (cabg) or received medical treatment (mt) after a viability study via dobutamine stress echocardiography (dse). methods: we considered patients with cad and left ventricular ejection fraction (lvef) <40% who were re...

blunt injury to the chest can affect any one or all components of the chest wall and thoracic cavity. the clinical presentation of patients with blunt chest trauma varies widely and ranges from minor reports of pain to florid shock. traumatic tricuspid valve regurgitation is a rare cardiovascular complication of blunt chest trauma. tricuspid valve regurgitation is usually begotten by disorders ...

mitral valve regurgitation (mvr) is a common valvular disease in dogs. hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (vfm), which shows the blood flow within the ventricles in vector and vortex flows. blood flow within the left ventricle of mvr dogs was compared at different stages of mvr and to that of normal dogs. 14 normal dogs and...

background and objective: congenital heart disease (chd) is the most form of cardiovascular disease in children. chd have different presentations, from defects that progress asymptomatically to those with significant symptoms and high mortality. this study was performed to highlight the importance of signs and symptoms to diagnosis of chd neonates. materials &amp; methods: this descriptive an...

conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...

objectives the aim of this study was to investigate the relation between respiratory muscle strength and the severity of chf, and the influence of respiratory muscle strength on abnormal ventilation during exercise in chf patients. conclusions respiratory muscle strength is related to the severity of chf, and associated with rapid and shallow ventilation or excessive ventilation during exercise...

conclusions we believe that the sh state in chf patients may be associated with the impaired pattern of circulating emps, with the predominantly increased number of apoptotic-derived microparticles. background subclinical hypothyroidism (sh) is diagnosed biochemically by the presence of normal serum free thyroxine concentration, in conjunction with an elevated serum thyroid-stimulating hormone ...

conclusions this is the first case report of a vanishing tumor in the right pulmonary apex. case presentation such masses have been designated as vanishing tumors of the lung. it is extremely rare that a vanishing tumor occurs in the apex of the lung. introduction in patients with acute heart failure, pleural fluid localized in an inter-pleural fissure produces a mass on chest x-ray, which mimi...
