I am afraid my brother in law has amyloid protein disease of the heart. He had open heart surgery on February 14 and just got home yesterday. He weighs 148 and was 190 in December. He had his aorta valve replaced, another valve repaired from a leak and the doctor said his heart was stretched and all the valves and ventricles were also and he said the walls were harder than normal. He is very weak, has swelling in his legs, ankles, feet, thighs, stomach. He has had one and sometimes 2 lungs tapped 6 times and then they finally put in drains that they are draining one every day now and the other every other day. He is getting 6 mile-liters from one and about 1 in the other. What do you think?
