My dad was taken to the hospital. He was not able to breathe and his chest hurt alittle. They determined no heart attack. He has congestive heart failure and his heart was beating irregularly. They did an echo test on him and he has a leaking heart valve. They also did a cath on him and he has a blockage in the back of his heart. Doctor said that he did not recommend stents and could not fix the blockage. IS this true? If not, why would they not correct his problem, He has Parkinson Disease, maybe this is a factor.
