Is there a difference in lv diastolic dysfunction and mild lv diastolic dysfunction ? what are the stages and does it always progress?

LVDD grading subject: The subjective scale of diastolic dysfunction: absent - mild - moderate - severe. Diastolic dysfunction is usually related to "stiffness" of the heart, which in turn, is attributed to the pressure of the blood flowing back to the heart that it has to deal with (diastolic blood pressure & pulmonary artery pressure). Depending on condition, the right medication can keep it from progressing. TTYD.
