Aim: To report a case of “end-stage” constrictive pericarditis with clinical manifestations such as ascites mimicking as cirrhosis of liver. Introduction: In “End-stage” constrictive pericarditis, the etiology remains unknown in majority of cases and inflammation plays a central role in its development. It has been readily confused with cirrhosis of liver in which there may be ascites, but veno...

Abstract On the basis of angular spectrum representation, a formalism describing paraxial beams propagating through an isotropic left-handed material (LHM) slab is presented. The treatment allows us to introduce the ideas of beam focusing and phase compensation by LHM slab. Because of the negative refractive index of LHM slab, the inverse Gouy phase shift and the negative Rayleigh length of par...

in this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...

we investigated neuronal uptake of noradrenaline (na) at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. the model presented here is the rabbit coronary ligation model in which myocardial infarction w...

although primary chronic hypertension (htn) is increasingly common in adolescence, secondary forms of htn are more common among children. primary htn is associated with being overweight and/or a positive family history of htn. carotid intima-media thickness, a known risk factor for atherosclerosis is frequent in both adults and children with htn and other associated cardiovascular (cv) risk fac...

background: sleep disorders are common among patients with chronic heart failure (hf), and it can have a significant effect on patients’ daily activities as well as their health. the purpose of this study was to assess sleep quality and its predictors in iranian patients with chronic hf.   methods : this cross-sectional study was conducted on a sample of 200 patients with hf in two hospitals of...

background: sleep disorders among heart failure (hf) patients negatively influence the quality of life. awareness of sleep disturbances, as one of the disturbing factors of the quality of life among hf patients, and its related factors would help health care staff to provide more comprehensive care. hence, this study was conducted to determine the quality of sleep and its related factors in hos...

background: several echocardiographic markers have been introduced to assess the left ventricular (lv) mechanical dyssynchrony. we studied dyssynchrony markers and the latest lv activation site in heart failure patients with and without left bundle branch block (lbbb). methods: conventional echocardiography and tissue velocity imaging were performed for 78 patients (lv ejection fraction ≤ 35%),...

objective: congestive heart failure (chf) has become one of the most important health care problems in western countries. this article focuses on the outpatient diagnosis and management of heart failure. we want to compare the outcome of patients who were treated with high dose diuretics in the emergency department (ed) without admission with patients who were admitted to hospital for standard ...

objectives: the aim of this study was to assess nutritional status and identify the most significant mna-items (mini nutritional assessment) to accelerate the determination of nutritional risk of heart-failure in elderly patients. methods and materials: the present research was a cross-sectional descriptive analytical survey on hospitalized heart- failure elderly patients (n=225). the sampling ...
