WebJan 7, 1997 · Ventricular diastolic dysfunction implies the requirement for elevated filling pressures to maintain cardiac output, resulting ultimately in congestive cardiac failure. Normal ventricular performance during early diastole is largely dependent on the process of active myocyte relaxation. WebJan 31, 2024 · Left ventricular (LV) diastolic dysfunction is a condition of impaired LV relaxation and increased LV chamber stiffness, which can lead to elevated LV filling pressures. This topic summarizes available echocardiographic methods for assessment of LV diastolic function.
WebIntroduction. Hypertension is one of the major risk factors for left ventricular (LV) diastolic dysfunction (DD) and heart failure with preserved ejection fraction (HFpEF). 1 Some previously documented sex-specific differences in structural and functional parameters of the heart and arteries may influence LV diastolic function in men and women. 2 … WebApr 10, 2024 · A person’s blood pressure is measured by the balance between diastolic and systolic pressure in the heart.
