echocardiographic 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 کاملArterial pulsatile hemodynamic load induced by isometric exercise strongly predicts left ventricular mass in hypertension.
Although resting hemodynamic load has been extensively investigated as a determinant of left ventricular (LV) hypertrophy, little is known about the relationship between provoked hemodynamic load and the risk of LV hypertrophy. We studied central pressure-flow relations among 40 hypertensive and 19 normotensive adults using carotid applanation tonometry and Doppler echocardiography at rest and ...
متن کاملLeft Ventricular Myocardial Function in Children With Pulmonary Hypertension: Relation to Right Ventricular Performance and Hemodynamics.
BACKGROUND Through ventricular interdependence, pulmonary hypertension (PH) induces left ventricular (LV) dysfunction. We hypothesized that LV strain/strain rate, surrogate measures of myocardial contractility, are reduced in pediatric PH and relate to invasive hemodynamics, right ventricular strain, and functional measures of PH. METHODS AND RESULTS At 2 institutions, echocardiography was pr...
متن کاملLeft ventricular contractile performance, ventriculoarterial coupling, and left ventricular efficiency in hypertensive patients with left ventricular hypertrophy.
Contractile performance of hypertrophied left ventricle may be depressed in arterial hypertension. Ventriculoarterial coupling is impaired when myocardial contractile performance is reduced and when afterload is increased. The left ventricular contractile performance and the ventriculoarterial coupling were evaluated in 30 hypertensive patients with moderate left ventricular hypertrophy and 20 ...
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...
