Relationship between the extent of non-viable myocardium and regional left ventricular function in chronic ischemic heart disease.
PURPOSE To define the relationship between left ventricular (LV) regional contractile function and the extent of myocardial scar in patients with chronic ischemic heart disease and multi-vessel coronary artery disease. METHODS Twenty-three patients with chronic ischemic heart disease and 5 healthy volunteers underwent magnetic resonance imaging (MRI). In patients, the relative area (Percent S...
متن کاملRelationship between myocardial viability and improvement in left ventricular function and heart failure symptoms after coronary artery bypass surgery.
BACKGROUND The evaluation of myocardial viability is an important preoperative parameter, predictive of improvement in regional and global left ventricular (LV) function after coronary artery bypass surgery (CABG). However, whether the presence of viability is also associated with relief of heart failure symptoms after revascularization is not always certain. The aims of the study were to defin...
متن کاملPrevalence of myocardial viability as detected by positron emission tomography in patients with ischemic cardiomyopathy.
BACKGROUND Detection of myocardial viability is important in patients with ischemic cardiomyopathy. Restoration of blood flow to viable myocardium is associated with improved left ventricular function and improved patient prognosis. However, the prevalence of viable myocardium in patients with ischemic cardiomyopathy is unknown. METHODS AND RESULTS To determine the prevalence of myocardial vi...
متن کاملThe Correlation between Left and Right Ventricular Ejection Fractions in Patients with Ischemic Heart Disease, Documented by Cardiac Magnetic Resonance Imaging
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...
متن کاملPrevalence of myocardial viability assessed by single photon emission computed tomography in patients with chronic ischaemic left ventricular dysfunction.
OBJECTIVE To assess the prevalence of myocardial viability by technetium-99m (Tc-99m)-tetrofosmin/fluorine-18-fluorodeoxyglucose (FDG) single photon emission computed tomography (SPECT) in patients with ischaemic cardiomyopathy. DESIGN A retrospective observational study. SETTING Thoraxcenter Rotterdam (a tertiary referral centre). PATIENTS 104 patients with chronic coronary artery diseas...
