Exercise capacity in patients with severe left ventricular dysfunction.
Normal or near-normal exercise capacity has been thought to reflect normal left ventricular function. Many compensatory mechanisms could preserve exercise capacity in patients with severe left ventricular dysfunction. We evaluated exercise capacity using a treadmill exercise test in 26 patients with severe left ventricular dysfunction defined by a left ventricular ejection fraction of 30% or le...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
متن کاملHigh myocardial 18F-FDG uptake after chemotherapy in the presence of left ventricular dysfunction as well as 3-month later with no left ventricular dysfunction
Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...
متن کاملCapacity and Exercise Hemodynamics in Patients with Left Ventricular Failure
Resting hemodynamics improve during vasodilator administration in patients with congestive heart failure (CHF), but the effects of these agents on exercise is unknown. Twenty-two patients with class II or III CHF performed bicycle exercise to symptomatic maximum before and 90 minutes after random doubleblind administration of oral hydralazine (100 mg) and isosorbide dinitrate (40 mg) (11 patien...
متن کاملThe Relation between Left Ventricular Function and Serum Ferritin in Major Β-Thalassemia
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...
