Coronary artery disease and Left Branch Bundle Block
I had a stent put in about 7 years ago now. I recently had a stress test and it was stopped because they said I had a left branch bundle block. Is there a relationship to the blocked arteries that were not proven to need stents a few years ago? is this saying that they are all now blocked and I need more stents? I have no pain and no way to tell that I have the left branch bundle block. What is the treatment or is there one?
The presence of a new left branch bundle block (LBBB) may be associated with progressive coronary artery disease (CAD) and if so, it would increase your risk for a heart attack. If the only finding is a LBBB, w/o other evidence of insufficient blood supply to your heart (called ischemia), an alternative next step to prove more CAD is a CTCA. The results could indeed prove you have CAD, but since you are asymptomatic (no angina), that doesn't automatically mean you need a stent or bypass surgery unless you have developed so-called Left main disease.
In asymptomatic patients with heart disease, medical treatment is often superior to stenting (the treatment doctors might recommend if they find CAD).
Hope this helps,

I proactively requested a stress test, at 66, due to not having had one in 10 years and my sister just had emergency CABG, possibly with genetic factors causing the coronary artery disease. Stress test completed, problem found, angiogram done 2 days ago. Two blockages, 90%-95% occlusion of LAD near bifurcation; 75% occlusion of an artery on right side (don't remember...
