Thanks so much to everyone who commented here and in private emails on my brother's heart attack. We were all surprised when he was released yesterday from the hospital. So the congestive heart failure/fluid buildup must have gotten better (they gave him a chest x-ray to check). He now has to take care of himself for 1.5 weeks before he sees his new cardiologist for further information about the other blocked arteries and the pacemaker (which was discussed in the hospital). I hope he doesn't go back to smoking!!! And I hope he takes his pills like he should.
