Chf & Possible Hypothyroid

My husband has chf and he has severe anemia and high creatinine levels. He does have some symptoms of hypothyroid - cold when I am hot, excessive fatigue, always sleepy, breathlessness, and chest tightening. He is getting the blood and urine tests done tomorrow. The Dr thinks I am nuts when I bring it up but he is testing to keep me quiet. Am I wrong in believing there may be a correlation here?
