Two years ago, I was dx'd with CHF and tests indicated a totally blocked LAD, 90% for the RCA (stented) at time in ER, and 70% for circumflex branch. The trip to ER was after I worked several days finishing my basement. The environment was very dusty and I didn't wear a mask
and developed a lung problem .
Recently tests indicated a natural bypass of the LAD (totally occluded just below the branch) and the branch occlusion is not a problem. I never had angina (pain), but obviously ischemia was present.
My current medical problem is MV regurgitation (moderate down from severe) has reduced an enlarged heart to normal and an EF is 59% up from below 29%. My cholesterol is normal, proper weight, exercise, proper diet, etc. If I had had angina, the symptom probably would have been treated with a stent or bypass! At this time I don't know if having a stent was the best decision, but I was drugged at the time
and led to believe it was a matter of life or death. I now believe a stent injures the artery wall, and as a result this lesion can cause inflammation and another occlusion within days, months or years. With intervention (vascular medication), a natural bypass may not be called upon as the system does not interrupt an ischemic problem. Just a theory of mine.
