Taking Low-molecular-weight heparin (LMWH) when INR is below 1.7? (mechanical valve)

[erik]

Hi there,

I have a mechanical St. Jude in the aortic position, but besides that no other heart problems
My therapeutic INR range is 2 - 2.5
My cardiologist suggest to take a LMWH (Fragmin) when it is below 1.7 (for example, when I forgot to take the pills, doesnt happen very ofthen though)

Is there anybody that also follows this procedure?
Is this a scientic proven measure?

Best regards,

Eric
