A 70-year-old man with known CAD and prior stent placement 5 years ago presents with recurrent angina. Stress testing shows inducible ischemia. Angiography reveals 85% stenosis in the LAD distal to a patent stent, and 70% stenosis in the RCA. Which finding would support medical management over revascularization for the RCA lesion?
- A)Three-vessel disease with left main involvement
- B)No evidence of ischemia in RCA territory on stress imagingGABARITO
- C)Ejection fraction of 30%
- D)Recent non-STEMI in inferior wall
- E)Chronic kidney disease with creatinine 2.8
Explicação
Revascularization decisions are guided by both anatomic stenosis and functional significance. Absence of inducible ischemia in the RCA distribution suggests that despite the 70% angiographic stenosis, the vessel is not causing significant myocardial ischemia. ...
