We tested the hypotheses that angiotensin-converting enzyme insertion/deletion (I/D) and angiotensinogen 235 methionine/threonine (M/T) substitution gene polymorphisms influence angiotensin-converting enzyme and angiotensiongen serum concentrations and cardiac dimensions in 91 monozygotic and 41 dizygotic twin pairs. Cardiac dimensions were determined echocardiographically. Angiotensin-converti...

Echocardiograms were obtained on 27 adults with electrocardiographic criteria of left ventricular hypertrophy (LVH) to determine how echocardiograms might best identify LVH. Both the left ventricular (LV) posterior wall thickness and interventricular septal thickness were found by echocardiography to be increased (greater than or equal to 12 mm) in only 13 of 27 patients (48%) with LVH. The LV ...

introduction: this study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. materials and methods: this study was performed on total of 30 first and second extracted molar teeth (15 each). the mesiobuccal roots of each tooth were separated at the cement-enamel junction (cej) level and embedded in acrylic resin. the embedded roots were cut ...

Background—To assess the reliability of pediatric echocardiographic measurements, we compared local measurements with those made at a central facility. Methods and Results—The comparison was based on the first echocardiographic recording obtained on 735 children of HIV-infected mothers at 10 clinical sites focusing on measurements of left ventricular (LV) dimension, wall thicknesses, and fracti...

OBJECTIVES We examined the echocardiographic characteristics of highly trained American football players. BACKGROUND Intense physical training is associated with morphologic and physiologic cardiac changes often referred to as the "athlete's heart." Echocardiographic features peculiar to elite football players have not been described. METHODS We studied cardiac morphology and function as as...

OBJECTIVE We assessed the relation of diabetes and insulin resistance (IR) on left ventricular (LV) structure and function in African Americans. RESEARCH DESIGN AND METHODS Among those receiving echocardiograms in cycle 1 of the Jackson Heart Study, we assessed the sex-specific relation of fasting blood glucose (FBG), diabetes, and IR to LV structure and function, adjusting for age, systolic ...

Left Ventricular Hypertrophy has a risk of increasing the brevity of the population if left untreated. Quantitative aid in the diagnosis and prognosis of Left Ventricular Hypertrophy to field experts is very essential to classify the disease and proceed treatment. Endocardium segmentation of left and right ventricles is done through Local Chan Vese Model using Radial Charge Fitting Curve. This ...

1. Changes in left ventricular structure and function were assessed by echocardiography in 22 patients before and after 9 months blood pressure control. 2. Nine patients had normal baseline echocardiograms (group 1) and 13 had echocardiographic evidence of left ventricular hypertrophy (group 2). 3. Group 2 patients demonstrated significant reductions in posterior wall thickness (P < 0.01), sept...
