Meaning and Clinical Context

The phase of the cardiac cycle during which the heart muscle relaxes and the chambers fill with blood, comprising approximately two-thirds of the cardiac cycle duration.

Diastolic function is assessed by echocardiographic parameters such as E/A ratio and e' velocity; abnormalities correlate with conditions like heart failure with preserved ejection fraction (HFpEF).

Turkish Translation

Diyastol

Example in Use

English: Impaired ventricular relaxation during diastole leads to elevated filling pressures, a hallmark of diastolic dysfunction commonly seen in hypertensive heart disease.

Turkish: Diyastol sırasında bozulmuş ventriküler gevşeme, hipertansif kalp hastalığında sık görülen diyastolik disfonksiyonun bir belirtisi olan yüksek dolum basınçlarına yol açar.

Clinical Notes

Scenario

A 72-year-old female with long-standing hypertension presents with exertional dyspnea; echocardiogram reveals abnormal mitral inflow patterns consistent with diastolic dysfunction.

Response Template

The patient's diastolic parameters show grade II dysfunction with E/e' ratio of 15; consider diuretics and strict blood pressure control.
