coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...

Abstract Objective Cardiac dysfunction is a major cause of death in patients with beta thalassemia. In these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. Left ventricular ejection fraction was measured in major beta thalassemia (β-Th) patients to detect the rela...

Background & Objective: Sternal wound infection and dehiscence are feared complications observed in 0.4-5% of cardiac operations. Even nowadays the mortality remains as high as 20-40%. The aim of the current study was to determine the rate of sternal wound infection. Material and Methods: The outcomes of 388 patients undergoing cardiac surgery during a 7 month follow up were analyzed and t...

Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...

INTRODUCTION AND OBJECTIVES The prognostic value of a single measurement of ejection fraction and peak oxygen uptake in chronic heart failure has been extensively investigated. The aim of our study was to evaluate the prognostic significance of serial changes in ejection fraction and exercise performance in moderate to severe chronic heart failure. METHODS 182 patients (156 men, 53 [47-58] ye...

conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

In 61 patients (77 studies) who had a transmural myocardial infarction, we compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by a computerized radioisotope technique that makes no assumptions regarding left ventricular geometry. In 31 studies of 26 patients with normal left ventricular wall motion by videotracking and normal left heart siz...

OBJECTIVES The purpose of this study was to determine the mathematical relationship between left ventricular ejection fraction and global myocardial strain. A reduction in myocardial strain would be expected to cause a fall in ejection fraction. However, there is abundant evidence that abnormalities of myocardial strain can occur with a normal ejection fraction. Explanations such as a compensat...
