Diastolic dysfunction beyond distensibility: adverse effects of ventricular dilatation.
Diastolic function has conventionally been assessed on the basis of the LV end-diastolic pressure-volume relation (Figure 1). A shift of this curve upward and to the left (curve A, Figure 1) has been considered to be the hallmark of diastolic dysfunction. In this situation, each LV end-diastolic volume is associated with a higher end-diastolic pressure, and therefore, the ventricle is less dist...
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 کاملEarly 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 کاملEffects of coronary venous pressure on left ventricular diastolic distensibility.
Coronary arterial pressure and flow are known to influence left ventricular (LV) diastolic distensibility, but the influence of coronary venous pressure is unknown. To test the hypothesis that increased coronary venous pressure leads to an increase in LV wall volume and a decrease in LV diastolic distensibility, we studied excised, blood-perfused LV isovolumic dog hearts without the pericardium...
