I have no known cardiac issues. Neither did my wife until last year when she had a heart attack. They did in angiogram and found a partial blockage. She has fully recovered with a stent. But if she held a 3rd class medical the FAA would have had an issue. Is there a cardiac test/screening/checkup that I could take that would not get the FAA worked up? I do routine colonoscopies for colon cancer and the FAA is ok with that. Is there a routine cardiac screening that does not say to the FAA, "This guy has some heart issues. We are not going to issue his next 3rd class medical" ? I would like to be proactive on this issue.
