The aim of this study was to determination and comparison of echocardiographic profile of elite Iranian weightlifters with non-athletes. Sample of research included 10 elite weightlifters with mean age of /2±1/218 years old and 10 non-athletes with mean age of 8/3±1/19 years old that As subjects participated in this study. The subjects were tested by one and two-dimensional echoca...
BACKGROUND Genome-wide association studies have identified single-nucleotide polymorphisms (SNPs) for subclinical cardiovascular outcomes in adults. We examined the influence of these variants on the same outcomes in childhood. METHODS AND RESULTS In a population-based prospective cohort study among 4137 children, we examined the associations of SNPs, individually and incorporated in genetic ...
AIM The aim of this study is to compare the ultrasound estimation of the cross-sectional area (CSA) and diameter of internal jugular vein (IJV) with left ventricular end diastolic area (LVEDA) for the assessment of intravascular volume in pediatric patients during cardiac surgery. PATIENTS AND METHODS The CSA and diameter of the left IJV were defined, using ultrasound machine, and compared wi...
PURPOSE To determine the usefulness of transcranial color-coded real-time sonography in detecting occlusion of the horizontal portion of the middle cerebral artery. METHODS Using transcranial color-coded real-time sonography, we measured the end-diastolic flow velocity with incident angle correction and the side-to-side ratio of the end-diastolic flow velocity (the end-diastolic ratio) in bot...
BACKGROUND Understanding the genetic architecture of cardiac structure and function may help to prevent and treat heart disease. This investigation sought to identify common genetic variations associated with inter-individual variability in cardiac structure and function. METHODS A GWAS meta-analysis of echocardiographic traits was performed, including 46,533 individuals from 30 studies (Echo...
The clinical utility of plasma natriuretic peptide concentrations in dogs with right-sided congestive heart failure (CHF) remains unclear. We investigated whether plasma levels of atrial natriuretic peptide (ANP) and N-terminal pro B-type natriuretic peptide (NT-proBNP) are useful for assessing the congestive signs of right-sided heart failure in dogs. This retrospective study enrolled 16 healt...
BACKGROUND Duplex ultrasonography criteria for assessing the severity of carotid artery (CA) in-stent restenosis are not well established. METHODS AND RESULTS We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound. Intravascular ultrasound measurements included minimum luminal diameter, percent...
The Doppler wave form along the proximal left internal thoracic artery (LITA), which is detected by the parasternal or suplaclavicular view, shows a different pattern from that of the distal side of the LITA due to the effect of blood pulsatility from the subclavian artery. We evaluated postoperative LITA function immediately after surgery with an apical approach of transthoracic pulsed Doppler...
OBJECTIVES We sought to better understand the effects of aging and gender on left ventricular (LV) structure and function. BACKGROUND Cardiovascular disease in older persons is associated with increased mortality and morbidity. The influence of gender on age-related cardiac changes is incompletely characterized. METHODS We studied 34 senescent, male and female, normotensive Fischer rats wit...
AIMS The aim of our study was to evaluate the influence of left ventricular (LV) diastolic filling impairment on postoperative results in patients (pts) with low LV ejection fraction (EF) (<35%) undergoing coronary artery bypass grafting (CABG). METHODS The study covered 56 patients (mean age 58.9 +/- 17.1 years). Two dimensional Doppler echocardiographic investigations were performed pre- an...
