BACKGROUND We examined the role of menopause on cardiac dimensions and function and assessed the efficacy of exercise training before and after menopause. METHODS AND RESULTS Two groups of healthy premenopausal (n=36, 49.4±0.3 years) and postmenopausal (n=37, 53.5±0.5 years) women with no history of cardiovascular disease and with a mean age difference between groups of only 4 years were stud...

Cardiac structural adaptations in response to physical growth and obesity in older children have been identified and might have long-term consequences. We examined the associations of growth and obesity with cardiac structures during the first 2 years of life. In a population-based prospective cohort study among 974 children, left atrial diameter, left ventricular diastolic diameter, left ventr...

Background- To investigate the role of endothelial nitric oxide synthase (NOS3) in left ventricular (LV) remodeling after myocardial infarction (MI), the impact of left anterior descending coronary artery ligation on LV size and function was compared in 2- to 4-month-old wild-type (WT) and NOS3-deficient mice (NOS3(-/-)). Methods and Results- Two days after MI, both strains of mice had a simila...

Results The age was 48±13 years old and 69% were men. Most of patients (88%) were in functional classes I and II, under a conventional treatment for cardiac insufficiency. The fraction of ejection of the left ventricle was 39±13%. The indicators of diastolic function associate to those of systolic function and the functional class. The carriers of pseudonormal or restrictive pattern of diastoli...

Background: Thalassemia is one of the common inherited blood disorders and Beta Major a homozygous form deficiency beta globin chain synthesis causing severe transfusion-dependent anemia, manifesting between 6 24 months life. Objectives: The objective study to pattern cardiac function in children adolescents with beta-thalassemia major by 2D Echocardiography its correlation serum ferritin level...

mendations about external diameter.2 While internal diameter is important for the airway resistance, the magnitude of the external diameter may play a role in the development of postintubation airway edema, postintubation croup and subglottic stenosis in pediatric patients. Therefore, when choosing a certain size of tracheal tube in children, both internal and external diameters should be taken...

Curves relating left ventricular end-diastolic pressure (LVEDP) to echocardiographically determined end-diastolic diameter (LVEDD) were obtained before and after ischemic arrest in 15 patients during open heart surgery. LVEDP ranged from 0-20 mm Hg during routine operation of the heart-lung machine. Ischemic arrest ranged from 0-94 minutes. In eight patients averaging 21 ± 7 (SEM) minutes of ar...

OBJECTIVE This study is the first in a series investigating the relationship between autonomic nervous system dysfunction and chronic cerebrospinal venous insufficiency in multiple sclerosis patients. We screened patients for the combined presence of the narrowing of the internal jugular veins and symptoms of autonomic nervous system dysfunction (fatigue, cognitive dysfunction, sleeping disorde...

conditional monitoring is prerequisite to prevent severe damage or falling down the trees. problems such as trunk decays, reduces trees resistance against wind and floods. in this study, a mathematical modeling technique is being selected to determine the trees strength against such events. finally, an applicable model for safety factor was created by having numeral (dimensions of crown and tru...

Our aim was to analyze any changes during diastole in patients with normal left ventricular ejection fraction (LVEF), after pacemaker stimulation from the right ventricular outflow tract (RVOT) and right ventricular apex (RVA) lead position. This was a prospective, randomized, follow up study, which lasted for 12 months. Our research included 132 consecutive patients who were implanted with a p...
