Is diastolic dysfunction a significant concern?

Question

Hi doctor,

I am a 59-year-old male, weighing 507 pounds and standing 5 feet 11 inches tall. I have been suffering from high blood pressure for the past 15 years and am currently taking Metoprolol, along with a combination of Triamterene and Hydrochlorothiazide. I underwent an echocardiogram four years ago, which was mostly normal, except for an enlarged left atrium measuring 52 mm and moderate mitral regurgitation. Last year, I had another echocardiogram, and the results showed minimal changes. I still have moderate regurgitation, but it also indicated grade 2 diastolic dysfunction and mild left ventricular enlargement measuring 58 mm.

I exercise and walk five days a week, and I have lost some weight, but I am concerned about my test results. The findings were not explained in detail, so I am trying to understand them better. My ejection fraction (EF) is 60 percent. I have attached my reports for your reference, which indicate that there are no regional wall abnormalities.

Please explain the condition of my heart.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

Do not worry; your report is not that bad. Most regurgitant lesions are well tolerated by the body. Unless you are experiencing symptoms such as breathlessness or angina, there is no need for concern. I recommend repeating your echocardiogram once a year and continuing your medications, including Metoprolol and Hydrochlorothiazide.

I hope this helps you.

Thank you.

Hi,

Welcome back to icliniq.com.

Diastolic dysfunction refers to an abnormality in the diastolic phase of the cardiac cycle, during which the ventricles fail to relax properly and become stiff, preventing them from filling with blood adequately. As we age, the arteries and heart muscle naturally become stiffer, leading to a decrease in their ability to relax. Grade 2 diastolic dysfunction is the mildest form of diastolic heart failure and is characterized by an abnormal relaxation pattern. Patients are usually asymptomatic. Since you are already taking Metoprolol, no additional medication is required. I recommend repeating your echocardiogram every six months and following aggressive lifestyle changes.

I hope this helps you.

Thank you.
