"His number was 800 a yr ago and now it's 4500 in just that short of time."

I assume that number is referring to B-type Natriuretic Peptide (BNP) test results.

As applicable, BNP is secreted by the heart's ventricles (lower pumping chambers) in response to a worsening of congestive heart failure (CHF).

A level that high is way way into the severe heart failure category. CHF can often cause shortness of breath (dyspnea), among other symptoms.

He's got a-fib and a leaky heart valve also."

Of course, conditions such as atrial fibrillation (a-fib) and valvular regurgitation (leakage) can make matters much more.

"He stops breathing when he sleeps also."

Sleep apnea alone may/can contribute to the development of heart failure as well as its worsening.

Most important, communicate well (even if only over the phone) with his doctors at ALL times.

Best of luck to your dad down the road of life.

Take care,

Be well-informed

Understanding Your Ejection Fraction

**To get a decent estimate of LVEF, a MUGA scan is reported as being the most accurate of the non-invasive methods.

Pertinent excerpt from an article - Richard N. Fogoros, M.D.

When is the MUGA scan more useful than other heart tests?

The advantages of the MUGA scan over other techniques (such as the echocardiogram) for measuring the LVEF are twofold
. First, the MUGA ejection fraction is highly accurate, probably more accurate than that obtained by any other technique. Second, The MUGA ejection fraction is highly reproducible. That is, if the LVEF measurement is repeated several times, nearly the same answer is always obtained. (With other tests, variations in the measured LVEF are much greater.)

James Beckerman, MD, FACC responded:
I'm guessing that the number you are referring to is "BNP" - this is a blood test that doctors use to help assess whether someone is in congestive heart failure, and generally higher numbers suggest that a person's heart is more congested. More important than the number, though, is how he is feeling, how well he is breathing, his oxygen saturations, etc. I wish him the best during this hospitalization towards a quick recovery.
