I am 68 yrs old male, already 3 yrs back I had a stent in RCA distal. Now i went through a gated myocardial perfusion spect. The findings showed normal ventricular cavity with moderately reduction of uptake involving mid segment of anterolateral wall together with moderate to severe reduction of uptake in basal inferior wall. The hypoperfused area shows partial reperfusion on resting re-injection study. Decreased tracer uptake in distal anterior wall and apex which became more conspicuous on resting re-injection scan. My LVEF is > 70%. As a layman could someone tell me my situation. Do i need a heart bypass, or angiography or medication?
