background: erythropoietin (epo) is known as a regulating hormone for the production of red blood cells, called erythropoiesis. some studies have shown that epo exerts some non-hematopoietic protective effects on ischemia-reperfusion injuries in myocytes. using echocardiography, we evaluated the effect of epo infusion on reducing ischemia-reperfusion injuries and improvement of the cardiac func...

Objective: To investigate the effect of sacubitril-valsartan combined with Zhenyuan capsule in treatment chronic heart failure comorbid anxiety and depression its on level inflammatory factors. Methods: A total 106 patients from February 2020 to March 2022 were continuously enrolled divided into control group (36 cases), observation cases) B (34 according methods. All groups given conventional ...

Using a high-frequency linear transducer (15L8), we studied 1) the feasibility of performing echocardiography in nonanesthetized mice compared with mice given pentobarbital sodium (Pento) or a mixture of ketamine and xylazine and 2) the feasibility of echocardiographic evaluation of left ventricular (LV) hypertrophy, dilatation, and function in mice with two-kidney, one-clip hypertension or myo...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

OBJECTIVES The aim of this study was to determine if left ventricular preload, afterload or contractility is a correlate of left ventricular mass index in hypertensive pediatric patients. BACKGROUND It is believed that decreased contractility and increased preload are associated with left ventricular hypertrophy in adult hypertensive patients. METHODS Ninety pediatric hypertensive patients ...

We studied the exercise ejection fraction response in 56 patients with chronic aortic insufficiency. All had left ventricular dilatation but preserved resting ejection fraction and minimal or no symptoms. The exercise ejection fraction increased by 0.05 units or greater in 18 (32%) patients (group I), remained within 0.05 units of the resting value in 18 (32%) patients (group II), and fell by 0...

In nine conscious, chronically instrumented dogs, ultrasonic dimension transducers measured left ventricular anterior-posterior and septal-free wall minor axis and major axis diameters. Matched micromanometers measured right and left ventricular transmural and transeptal pressures. Ventricular pressures and volumes were varied by inflation of implanted vena caval and pulmonary artery occluders,...

BACKGROUND The first generation of cardiac resynchronization therapy (CRT) devices approved for the treatment of heart failure used simultaneous biventricular (BiV) pacing to achieve ventricular resynchronization. Left ventricular pacing alone and sequential BiV pacing also show promise as alternative ways to deliver CRT, but have not been studied together in a large randomized trial. METHODS...

background: cardiac dysfunction due to chronic anemia and hemosiderosis are the major causes of death among patients with thalassemia intermedia. this study was performed to compare the cardiac function in thalassemia intermedia patients with normal subjects by means of echocardiography. materials and methods: this was a case-control study performed on 22 patients affected by thalassemia interm...
