This is my first post here, my husband has been in AF for two years due to Graves Disease. He is 52, he has finally been scheduled for a Cardioversion this Friday, 3rd June. His INR was checked yday and is 1.9, target is 2 or above . His previous reading was 2.4 on 5th May, and 2.3 on 7th April. We though he was on track. The healthcare asst has not adjusted his dosage of Warfarin and has kept him on the dose calculated on 5th May. Is there anything he can do between now and Friday to get the INR up to 2 again. I wondered if the warmer weather could be causing a bit dehydration & therefore thicker blood? I am also wondering whether the HA should have upped the Warfarin? Many thanks.
