Diastolic Left Ventricular Dysfunction A Clinical Appraisal
Objective: In dilated cardiomyopathy and in athlete’s heart, progressive LV dilatation is accompanied by rightward displacement of thediastolic LV pressure–volume relation. In dilated cardiomyopathy, an increase in diastolic LV stiffness can limit this rightwarddisplacement thereby decreasing LV systolic performance. Because nitric oxide (NO) reduces diastolic LV stiffness, the present ...
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 کاملTherapeutic strategies for diastolic dysfunction: a clinical perspective.
Diastolic dysfunction, which is increasingly viewed as being influential in precipitating heart failure and determining prognosis, is often unrecognized and has therapeutic implications distinct from those that occur with systolic dysfunction. In this review, several therapeutic modalities including pharmacologic, nonpharmacologic, and surgical approaches for primary diastolic dysfunction and h...
