Early 50's..i have call it 30% blockage in my lada...lbbb..slight output issue;meds for hbp..what can i do to lessen chance of more heart afflictions?

Optimization medicin: Plus lifestyle changes (walk even daily 30 mins, eat as much of a MEditerranean diet as possible, and de-stress = meditate). Given your LBBB, some plaque buildup and possible decrement in LVEF, make sure you are on the "holy water"= asprin 81mg, betablocker, preferably Coreg, (carvedilol) ACE inhib, statin. This combo + heart healthy lefstyle ought to stave off heart disease and hopefully reverse low output
