Coronary artery disease and Left Branch Bundle Block
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,

If ef was 25% and after 2 yrs it is 50%, should carvedilol be reduced? Carvedilol is 12.5mg 2x with Losartan at 25mg. I exercised during those two years for 30 min four times per week. Started with water aerobics and then treadmill. Added yoga recently.
