I am 22yr old and I had viral myocarditis on april. Susequently I had
congestive heart failure and later on diagonised with dilated cardiomyopathy.
My EF went down to 20% and cardiac output to 2litre/minute. I was put under
immunosuppression treatment and since then I have drasticaly improved physically,
I can alomost do whatever I want. But my EF has not improved although my
cardiac output has increased to 4. I thought that if the cardiac output increases
then EF should also increase. I don't understand why my EF has not increased.
Thanks for your time, awaiting your reply.

Dear Cheryl
Cardiac output incorporates several other parameters, such as heart rate; if your heart rate increases, your cardiac output usually goes up, even if your heart pumping function is no better. This is one of many ways that the body compensates for a weak heart. The muscles of the body also become more efficient, adjusting to the low ejection fraction.
I hope this is useful. Feel free to write back. I wish you the best of luck.
If you would like to set up an appointment with one of our cardiologists here at the Cleveland Clinic please feel free to call 1-800-CCF-CARE.
