global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...
The purpose of the work presented here was to investigate endotheliumdependent relaxations in the rabbit coronary ligation model of heart failure. We investigated endothelium-dependent relaxations at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal e...
We investigated neuronal uptake of noradrenaline (NA) at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. The model presented here is the rabbit coronary ligation model in which myocardial infarcti...
Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them. Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...
Listen to the heart sounds gives us valuable information about existence of disorder in heart rate and rhythm, ventricular fibrillation and movement of blood through valves. This required a lot of skills. So it is necessary to understand and apply these skills for nurses in cardiac and intensive care. Abnormal sounds can be recognized by them. For facilitation this work, nurses should be have...
Abstract Background; the MYH7 and MYH7b genes have important role on heart function on other hand endurance training is a challenge for heart function, therefore the aim this study was to study The effect of endurance training[a2] on Change of MYH7and MYH7b genes expression and left ventricular structural changes of wistar male rats. Material and Methods; For this purpose, 14 rats (113±20...
background: desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. the aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. methods: this interventional ...
Introduction & Objective: Heart failure that is a major health problem with increasing incidence with the aging of the population often occurs as a result of ischemia and coronary artery disease. Allopurinol can protect the ischemic heart muscle and improve the use of energy during myocardial ischemia. The aim of the present study was to evaluate the effects of allopurinol on the left ventric...
Hypertonic saline solution can absorb part of the intracellular fluid volume into the extracellular space. The effects of this solution on the cardiovascular system are increased coronary flow and increased left ventricular contraction, without sympathetic system activation. This study was designed to assess the effects of hypertonic saline solution in open heart surgery and to compare it w...
Background: AMPK and P53 proteins regulate the TOR protein in the TORC1 complex, which regulates many physiological processes. The aim of this study was to evaluate the effect of AMPK and P53 proteins on the TOR pathway following endurance training in the left ventricle of the heart of diabetic rats by streptozotocin and nicotinamide. Methods: In this experimental study, 12 head two-month-old ...
