The problem is that you have to take medication after stenting, especially aspirin and clopidogrel, the former for life and the latter for at least 1-3 months, but since it is unpredictable when the hematologic disease will recur, if it does, you may not be able to take aspirin and clopidogrel. However, since it is unpredictable when a hematologic disorder will recur, if it does, you may not be able to take aspirin and clopidogrel, which would put you at risk of intra-stent thrombosis, especially if it recurs within 3 months after surgery. Therefore, if the angina is really severe and cannot be controlled by regular medications, stenting or simple balloon dilation can be considered, but in this case, it is reasonable to consider a bare stent, which has a lower risk of in-stent thrombosis, but the patient needs to understand the possible risks after surgery.
