Still had terrible pain kept me in the E.R. for hours (8) finally decided to do an echocariogram determined tamponide rushed me to the o.r. 2 weeks later had severe chest pain. They did a catheter determined a by pass collapsed. Since then I've had 17 stints and still severe chest pain upon exertion. I'm on all beta blockers.
