Yes, David had a stress test, failed it; then an nuclear stress test; failed it; then EKG, failed it; then heart cath/angioplastio/whatever -- they went in through the femoral artery & did the camera thing -- that's when they found the 90% blockage, BUT it was in an "extra" artery -- most people have 2 arteries on the front of the left side of the heart; David has three... we don't have a clue, 2nd opinion this week, keeping our fingers crossed. In the meantime, ordered Explorer charts and cruising guides to cruise the southern Bahamas this year ... a bit more conservative than we'd like, but maybe suited to our health limitations right now....
