I've had some irregular heartbeats and stress test shows possible blockage. They want to do heart cath, then possible angioplasty. My question is this: Could a 10 day Water Fast clear the blockage so I don't have to go thru all that? I have not had any chest pain, just trouble breathing on exertion. I wanted to start exercising again and this is when all that came up. I was able to do the treadmill stress test so I did not need the chemically induced test. I feel pretty good...they sais I could wait a week if I wanted - just the sooner the better.
