My husband had a stress test done. When he was finished his chest was hurting terribly but Dr. Williams said that everything was fine and he could go home. On the way to the car, we had to stop several times for my husband to rest. We talked to several other people who had problems similar to my husband's and most of them said that they had a heart cath done. We ask Dr. Williams about having one done and he said we didn't need it. He said he would check everything on our next visit (in a year). After a lengthy conversation, Dr. Williams finally agreed to do a heart cath the next day. It was discovered that my husband had blockage in his arteries and had to have stents put in.
