Nuclear stress w/ lexiscan shows moderate to severe ischemia anterior/apical wall. cath scheduled, doc thinks no blockage, why? i have lbbb; no other defects lv normal size and function, 50% ef. y?

Cath= gold standard: The catheterization will identify any obstruction or blockage. Your EF is just fine.

Need cath: I do not know why the doc feels no blockage. If the stress is abnormal you need to clear up why this is. if you are having these tests, you have had to have had symptoms. 50% Ef is good and the echo being normal does not tell us why. Have the cath. Males are more likely to have abnormal caths and may require some intervention.
