During the dolbutamine stress echo my ekg showed I had a heart attack. I was then rushed off for an emergency cardiac cath in which no blockages or damage was found. Could the change in the EKG have been a reaction to the drug?I was discharged a day later and given a script for Norvasc and Plavix. I was told that my heart attack could have happened then or with another activity. But being I had no blockages, was it caused by the injection of Dolbutamine?
