unobstructed coronary arteries -- keywords
The following is an initial stab at this search. It would be far more specific if the "AND" could be replaced by a proximity indicator. Alas, this option is not available in PubMed.
((normal OR negative OR "no stenosis" OR stenosis-free OR astenotic OR patent OR unblocked OR unobstructed OR clear ) AND (MRA OR CTA OR angiograph* OR "coronary artery" OR "coronary arteries" ))
