Interpeting progress notes from my cardiologist

[blaguna22]

Hi,  my name is Bill, and I am 58 years old.  I am a retired physical education teacher/baseball coach/high school administrator.  I thought I was in pretty good shape. (6' tall/205 lbs) I do have high blood pressure.  Long story short, I had the shock of my life last December.  I was told I had a mild heart attack.  The angiogram confirmed severe blockage.   So,  I had a quadruple by-pass surgery 4 months ago!  The following notes are from my 4 month "follow up" exam in which an echocardiogram was performed to check out my heart.  His notes are as follows:'
2D echo on 3/15/16:  ED 50% with anterior and lateral akinesis.  Severe left ventricular hypertrophy.  Left atrium enlarged up to 5.2 cm.  Right atrium enlarged.  Mild mitral regurgitation.  Mild tricuspid regurgitation.  Stage 1 left ventricular diastolic dysfunction.  
  My Dr. told me that I am at 50% "heart effectiveness".  That didn't sound too good, but he says that I'm ok and not to worry.  After looking at his notes, I am worried.  Can you please help me understand his notes.  He is not a very good communicator to say the least!
     FYI, I do feel great though! I have come through this surgery with very high marks for the recovery process.  I have completed my cardiac rehab and am continuing my physical fitness routine, along with a heart healty diet.

You may want to post your question on the Heart Disease forum as opposed to the Heart Rhythm forum to get better feedback.  This said, if the doctor wasn't overly concerned I would trust his judgment.  I personally don't know much about heart attacks and how much a person can recover from them but if you feel good and are taking steps to have a heart healthy lifestyle it could mean that your 50% strength will improve with time.  I do know the heart can recover from a lot but it takes a long time so just keep doing what you are doing and hopefully things will improve more for you or at least not get any worse which is good considering you say you feel well.  If you are concerned or have further questions there is nothing wrong with contacting your doctor's office for further clarity.  I know mine has an email feature that is helpful.  But either way you have a right to ask more questions.  Or make an appointment with him to specifically ask questions.  Or you can try to see a different doctor for a second opinion.  In any event, post your question in the Heart Disease section and you may find some people who have more experience with heart attacks who can give you some insights on the technical terms that you were told.  Take care.
