Hlo sir/Mam. Is normal stress echo sufficient to rule out possibility of heart blockages/angina in an intermediate risk patient with typical angina symptoms ( 26/M, no sugar/lipids/family history)? And how often shud I be going for stress echo to ensure it's all fine with my heart? My doc told me about CT angio but wants me to avoid it due to radiation and allergic reaction risk ( I take l-hist mint already)? Just require a second opinion to get out of the dilemma n be happy with my negative stress echo results
