I'm a 52 yr old male in good physical health have worked out, both cardio and resistance, my entire life. Never had any heart issues or symptoms until a year ago when I was working out got light-headed and had some very mild chest discomfort. Over the next 2 weeks I was in the ER five times thinking I might be starting to have a heart attack. All bloodwork normal, no positive signs for HA. This lead to a stress test with nuclear imagining, 24/7 heart monitor for 20 days, heart echo.... all negative. And eventually lead to a catheterization angiogram at Univ of Madison, WI hospital. There was no obstructive coronary disease found, but a 'prominent' myocardial bridge (MB) of the LAD was noted. I was told it was a benign finding and would not cause symptoms. From there I have been to the Cleveland Heart clinic (#1 in the nation) and told the MB was benign, Mayo Clinic in Rochester who repeated all heart test and told the MB was benign and heart was fine, and finally Stanford Medical in CA who has a myocardial bridge specialist by the name of Dr Schnittger. She looked at the cath angio film and said the MB is very significant and the LAD is obliterated during diastolic. Stanford then did another cath angio with specific testing of the hemodynamics of the MB and found the fractional flow rate (FFR) to be only .72 (anything less than .8 is bad). (FFR is the single most important measurment in defining the significance of an MB, or a static diseased vessel, but most places do not have the means to measure it.) Dr Schnittger believes unequivically that I should have debridging surgery to release the LAD from the bridge. While not a common surgery, it has been performed since the 70s and has proven to be very successful at resolving symptoms with very few surgical complications. To date I have not undergone surgery as I feel normal on a day to day basis, the only time I feel any symptoms is during exercise and if I don't push it, keep heart rate <140 and stay under 40 minutes of exercise, I basically have no symptoms. If I push it beyond those limits, my heart rate will stay in the 80s for hours after the exercise (normal resting is mid-high 50s) and I will feel like all the energy has been sucked out of my upper body... very weak for several hours. Surgery can now be done without a sternotomy, with a beating heart (no heart lung machine) and in a few very select centers completely robotically. Feel free to contact me if you would like any more specific info, I have a ton.
