Introduction: Increased oxidative stress is involved in the pathology of cardiovascular disease. Transient congenital hypothyroidism (TCH) leads to a variety of heart disorders during adulthood. In this study, the effect of TCH on antioxidant and oxidant systems in the serum and left cardiac ventricle of adult male rats was investigated. Materials and Methods: TCH was induced by administrating ...
Background: Cardiovascular problems including arterial hypertension, coronary artery diseases, congestive heart failure are prevalent among chronic hemodialyzed patients. Ultrafiltration of hemodialyzed patient's serum, which culminating in intravascular volume reduction, is frequently used during hemodialysis. One of the restrictions of the echocardiographic evaluation of the diastolic heart f...
Background: With the development of technology, human beings are increasingly under the exposure of Radio Frequency Radiation (RFR) (due to wireless technologies, mobile phones, base stations etc). The aim was to investigate the possible effects of Radio Frequency Radiation (RFR) on blood, aorta and heart tissue in hypertensive and non-hypertensive rats with various parameters. Materials and Me...
Background: Cardiac connective tissue dysplasia syndrome consists of mitral valve prolapse (MVP), anomalously located chordae tendinae of the left ventricle, or a combination of the two. MVP is marked by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. The nonclassic form of MVP carries a low risk of complications. Patients with severe classi...
the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...
Objective(s) In addition to antihypertensive effects, amlodipine may exhibit cardiovascular protective effects in heart tissue. The aim of this study was to evaluate the effects of amlodipine and/or high cholesterol diet on blood, heart tissue concentration and mRNA expression of endothelin-1 (ET-1) in male New Zealand white rabbits. Materials and Methods A total of 40 male New Zealand rabbi...
Background: The aim of this study was to evaluate the effect of eight weeks of endurance training and Empagliflozin consumption on inflammatory markers and their relationship with heart structure and function of diabetic male Rats. Methods: 40 male Wistar rats were randomly divided into five groups: healthy control, diabetic control, diabetic + empagliflozin, diabetic + endurance training and ...
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
