Two vessels	11 (37%)	3 (43%)
Three vessels	9 (30%)	2 (29%)

Three patients showed spontaneous reperfusion in the coronary artery spam during the no-procedure period, but the procedure could not be pursued in one patient who had received bronchial artery embolization because of a continuing massive pulmonary hemorrhage.
