Chauges in Ventricular Volume, Wall Thickness and Wall Stress During Progression of Left Ventricular Dysfuncthu
To assess the long-term changes in cardiac function iu N tomatic patients with severe left veatricuiar dysfunction, left ventricular (clneangiography) and right ventricular (radionuelide angiography) function were assesxd at baseline in 49 patients enrolled in the prevention arm of the Studies of Left Ventricular Dysfuoction. After an average follow-up period of 12.4 months, 30 patients (11 ran...
متن کاملCalculation of left ventricular wall stress.
Chamber-stress equations relate wall stresses to pressure and wall dimensions. Such equations play a central role in the analysis and understanding of heart-chamber function. Over the past three decades, several stress equations giving radically different results have been derived, used, and/or espoused. They can be classified into two categories, according to the definition of stress underlyin...
متن کاملEffect of exercise training and L-arginine supplementation on oxidative stress and left ventricular function in rats with myocardial infarction
Introduction: The aim of the present study was to evaluate the effect of exercise training and L-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (MI). Methods: Four weeks after the surgically-induced MI, 40 male Wistar rats were randomly assigned to the following 4 groups (n=10): MI-sedentary control (Sed) MI-exercise (Ex) MI-...
متن کاملReduction in Left Ventricular Wall Stress and Improvement in Function in Failing Hearts using Algisyl-LVR
Injection of Algisyl-LVR, a treatment under clinical development, is intended to treat patients with dilated cardiomyopathy. This treatment was recently used for the first time in patients who had symptomatic heart failure. In all patients, cardiac function of the left ventricle (LV) improved significantly, as manifested by consistent reduction of the LV volume and wall stress. Here we describe...
متن کاملCorrelation of echocardiographic wall stress and left ventricular pressure and function in aortic stenosis.
Previous studies have suggested that left ventricular pressure (P) can be predicted in patients with aortic stenosis by the equation P = 235 h/r, where 235 is a constant peak wall stress (sigma), h is end-systolic wall thickness, and r is end-systolic dimension/2; h and r are measured by M-mode echocardiography. In 73 patients with aortic stenosis (valve area less than 0.7 cm2), measured and pr...
