The Effect of Acute Changes in Coronary Blood Flow
نویسندگان
چکیده
The effect of acute alterations in coronary blood flow (CBF) on left ventricular (LV) end-diastolic wall thickness was measured by reflected ultrasound in twelve anesthetized dogs. During five minutes of coronary ligation, wall thickness decreased from a control of 9.0 ± 0.3 mm to 8.1 ± 0.3 mm (P < 0.001); during reperfusion (reactive hyperemia), wall thickness was greater than control (10.2 ± 0.2 mm at one minute, P < 0.001). Increased CBF produced

The Role of Nitric Oxide and Prostaglandins in the Effect of Adenosine on Contractility, Heart Rate and Coronary Blood Flow in Guinea Pig Isolated Heart
It is a well-established fact that adenosine and its receptor subtypes (A 1 and A ) are involved in changes of contractility, heart rate and coronary blood flow (CBF) under different circumstances. This study was conducted to evaluate the role of nitric oxide and prostaglandins in development of these changes. For this purpose, Nitro-L-Arginine methyl ester (L-NAME), and indomethacin as inhibit...
متن کاملEffect of Cardiac Rehabilitation Program Based on Combined Training on VEGF/Endostatin Gene Expression Ratio in Patients with Acute Coronary Syndrome
Background: Coronary artery disease is one of the most common causes of death in the world. With the increase in the incidence of these diseases, surgical and non-surgical interventions followed by cardiovascular rehabilitation programs have become more important. The process of angiogenesis and improvement of blood flow is considered as one of the therapeutic goals in these patients, and vascu...

Background and Aim: Inactivity increases the risk of chronic diseases. The aim of the present study was to investigate the acute changes in Normetanephrine and glucose in boxing with Kinect Xbox with and without blood flow restriction as an alternative to aerobic exercise during quarantine in young non-athletes. Material and Methods: Fourteen healthy non-athlete individuals with a range of 20 ...
متن کاملRelationship between demographic and clinical factors with electrocardiography deviation as a prognostic factor in acute coronary syndrome patients
Background: Acute coronary syndrome (ACS) is one of the causes of disability and death. Levels of Uric acid, blood glucose, and dyslipidemia are the risk factors for the disease, but their role in electrocardiographic changes has not been studied. Based on this, this study aimed to investigate the relationship between some demographic and clinical characteristics with electrocardiographic chang...
متن کاملAn advection-diffusion multi-layer porous model for stent drug delivery in coronary arteries
Arterial drug concentration distribution determines local toxicity. The safety issues dealt with Drug-Eluting Stents (DESs) reveal the needs for investigation about the effective factors contributing to fluctuations in arterial drug uptake. The current study focused on the importance of hypertension as an important and controversial risk factor among researchers on the efficacy of Heparin-Eluti...
متن کاملThe effect of turbulence model on predicting the development and progression of coronary artery atherosclerosis
A severe case of stenosis in coronary arteries results in turbulence in the blood flow which may lead to the formation or progression of atherosclerosis. This study investigated the turbulent blood flow in a coronary artery with rigid walls, as well as 80% single and double stenoses on blood flow. A finite element-based software package, ADINA 8.8, was employed to model the blood flow. The hemo...
