Yesterday evening I took Pat to the hospital with difficultities breathing and chest pains. he did not have a heart attack but the blood work shows a possible clot. None was found on the CT Scan. Today he is having lung tests done and in the morning he is having an arteriogram. One doctor believes it is lungs the other believes it is heart. It could be both. The only reason the arteriogram is not being done today is because the contrast is hard on the kidneys and they want the first dye to flush out of system before injecting more.
