Early diastolic filling dynamics in diastolic dysfunction
BACKGROUND The aim of the study was to determine the relationship between the rate of peak early mitral inflow velocity and the peak early diastolic mitral annular tissue velocities in normal controls and to compare them with subjects with diastolic dysfunction. METHODS The relationship between early passive diastolic transmitral flow and peak early mitral annular velocity in the normal and i...
متن کاملDiastolic dysfunction.
Diastolic dysfunction of the heart is characterized by normal left ventricular contractility and normal ejection fraction, however ventricular relaxation is impaired. In systolic dysfunction, ventricular contractility and ejection fraction are reduced, in addition to impaired relaxation. The prevalence of diastolic dysfunction is increased in the elderly, especially those who have had inadequat...
متن کامل[Diastolic dysfunction and diastolic heart failure].
There are frequent clinical Cases in Cardiological practice when cardiac failure develops together with normal systolic function of left ventricle. In these patients after revealing the diastolic dysfunction the heart diastolic failure is diagnosed, but in frequent cases this diagnosis is based on exclusion method. According to Framingham data the number of patients with clinically manifested d...
متن کاملDiastolic filling dynamics in patients with aortic stenosis.
Left ventricular filling dynamics were investigated in 24 patients with aortic stenosis (AS). Biplane cineangiography was performed with simultaneous micromanometry in these 24 patients and in six control subjects. Twelve of the patients with AS had moderate hypertrophy with a left ventricular muscle mass index of less than 180 g/m2 (ASI group) and 12 had severe hypertrophy with an index of 180...
متن کاملA Noninvasive Method for Characterizing Ventricular Diastolic Filling Dynamics
We developed a novel method for estimating a single parameter (τD) which summarizes the diastolic filling dynamics of the ventricle that governs the effects of diastolic filling time on stroke volume. The method involves the analysis of beat-to-beat fluctuations in heart rate, arterial blood pressure, and left ventricular stroke volume, each of which may be measured noninvasively in humans. In ...
