introduction: sleep disturbance is common in patients undergoing coronary artery bypass graft surgery and has been subject to concern for more than 30 years. new literature suggests the importance of sleep and rest to restore, protect and promote performance and wellbeing of these patients. due to the important role nurses play to diagnose such disorders and to help patients get rid of these pr...

t rue saccular aneurysm is exceptional in coarctation of aorta in children. a 6-year-old girl with headache and systemic arterial hypertension referred to our center for cardiovascular evaluation. physical examination revealed high blood pressure and weak lower extremity pulses. two-dimensional and doppler echocardiography and angiography demonstrated a saccular aneurysm of the descending aorta...

Background: Cardiovascular disease (CVD) is the main cause of mortality in the world and is normally argued as the third cause of all mortalities. Opium and alcohol every day consumption can cause people to have many health problems. The present study aimed to assess the effect of ethanol and opium consumption on lipid profiles and atherosclerosis in aorta. Methods: Twenty four male golden Syri...

introduction: the correlation of central venous pressure (cvp) with inferior vena cava (ivc) sonographic diameter has been reported in several studies. however, few studies have attempted to find the best anatomic location of measurement. therefore, the purpose of this study was determining the best anatomic location to find precise correlation between cvp and ivc diameter using transesophageal...

• Many surgical procedures designed to increase the total blood flow to the heart or to distribute the existing flow more equitably have been proposed. 1 " 3 The assessment of these operations has been hampered in the past by: (1) difficulty in obtaining objective data from clinical patients, (2) lack of a method to measure capillary (tissue) blood flow to specific areas of myocardium, and (3) ...

OBJECTIVE ATP-sensitive K+ channels have been classified based on their inhibition by cytoplasmic ATP. Recent evidence in vascular smooth muscle has suggested that these channels show weak sensitivity to intracellular ATP. However, it is not known whether these channels regulate the resting K+ conductance in vascular smooth muscles. Therefore, the aim of the present investigation was to charact...

objective(s) four novel losartan analogues 5a-d were synthesized by connecting a dihydropyridine nucleus to imidazole ring. the effects of 5a and 5b on angiotensin receptors (at') and l-type calcium channels were investigated on isolated rat aorta. materials and methods aortic rings were pre-contracted with 1 pm angiotensin ii or 80 mm kcl and relaxant effects of losartan, nifedipine, 5a a...

Objective(s): Cardiovascular disease is a leading cause of morbimortality with over half cardiovascular events occurring in the asymptomatic population by traditional risk stratification. This preliminary study aimed to evaluate systemic plaque vulnerability in patients with prior Coronary Artery Disease (CAD) with a single Whole Body [FDG] PET-CT scan in terms of plaq...
