[Diastolic Dysfunction in CKD: Cause or Effect?s].

Left Ventricular Diastolic Dysfunction (LVDD) describes changes in the heart's structure and function, leading to impaired ventricular relaxation and increased filling pressures during the diastolic phase of the cardiac cycle. In the context of isolated LVDD, the left ventricular end-diastolic volume, global contractility, and ejection fraction (EF) are normal, with EF being 50% or higher. However, as filling pressures progressively increase, diastolic dysfunction worsens.
