What is Grade 3 diastolic dysfunction?

Grade 3 diastolic dysfunction is a severe impairment of the heart's ability to relax and fill with blood between heartbeats. It is the most severe of three grades of diastolic dysfunction.

Diastolic dysfunction occurs when the heart muscle is stiff or thickened, making it difficult for the ventricles to relax and fill with blood. This can lead to a number of symptoms, including shortness of breath, fatigue, and swelling in the feet and ankles.

Grade 3 diastolic dysfunction is often caused by underlying conditions such as high blood pressure, coronary artery disease, and diabetes. It can also be a result of certain medications, such as chemotherapy drugs and some antidepressants.

Treatment for grade 3 diastolic dysfunction typically focuses on managing the underlying condition and relieving symptoms. This may include medications to lower blood pressure, improve heart function, and reduce fluid retention. In some cases, surgery may be necessary to correct the underlying condition.

Grade 3 diastolic dysfunction is a serious condition that can lead to heart failure. However, with proper treatment, many people with grade 3 diastolic dysfunction are able to live long and healthy lives.
