Stress test stated moderate to severe ischemia anterior/apical. Heart cath says stress test false p,no blocks,but mild elevated EDP/LBBB. Is this causing dyspnea and exercise intolerance? Help?

In brief: Yes

Elevated EDP indicates left ventricular dysfunction.
You did not report what your ejection fraction (EF) is - it's crucial. Your EDP may be elevated from systolic and/or diastolic dysfunction. Moreover, LBBB causes dys-synchrony which further compromises LV function. Both abnormalities you list will result in impaired functional capacity manifested as exercise intolerance.

In brief: DiastolicDysfunction

Increased end-diastolic pressure or diastolic dysfunction can cause shortness of breath because the left ventricle doesn't relax enough between beats to accommodate all the blood coming in from lungs.
Usually BP control is the answer. Diuretics can help. LBBB doesn't usually cause symptoms. There are other non-cardiac causes of exercise intolerance that may need exploration.
