Ultrasonic backscatter and diastolic function in hypertensive patients.
This study was designed to assess whether ultrasonic reflectivity, evaluated by a real-time integrated backscatter analysis, was related to the severity of diastolic dysfunction, as studied by Doppler echocardiography in patients with essential hypertension. One hundred nine subjects were included in the study. Diastolic function was assessed by mitral-inflow Doppler ultrasound recordings. Back...
متن کاملA relationship between ultrasonic integrated backscatter and myocardial contractile function.
We have shown previously that the physiologic, mechanical cardiac cycle is associated with a parallel, cardiac cycle-dependent variation of integrated backscatter (IB). However, the mechanisms responsible are not known. The mathematical and physiological considerations explored in the present study suggest that the relationship between backscatter and myocardial contractile function reflects cy...
متن کاملAssociation between serum ferritin level and diastolic cardiac function in patients with major β-thalassemia
Abstract Background Prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. Our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. Materials and Methods Sixty-six patients with major thalassemia were studied in Amir Kabir hospital, Arak, Iran. Serum ferritin levels ...
متن کاملOne-Hour Postload Plasma Glucose Levels and Diastolic Function in Hypertensive Patients
OBJECTIVE To address whether glucose tolerance status, and in particular 1-h postload plasma glucose levels, may affect diastolic function in 161 never-treated hypertensive white subjects. Impaired left ventricular relaxation, an early sign of diastolic dysfunction, represents the first manifestation of myocardial involvement in diabetic cardiomyopathy. A plasma glucose value ≥155 mg/dL for the...
متن کاملLeft ventricular diastolic function in essential hypertensive patients: influence of age and left ventricular geometry.
PURPOSE To evaluate diastolic dysfunction (DD) in essential hypertension and the influence of age and cardiac geometry on this parameter. METHODS Four hundred sixty essential hypertensive patients (HT) underwent Doppler echocardiography to obtain E/A wave ratio (E/A), atrial deceleration time (ADT), and isovolumetric relaxation time (IRT). All patients were grouped according to cardiac geomet...
