Predictors of survival following extracorporeal cardiopulmonary resuscitation in patients with acute myocardial infarction-complicated refractory cardiac arrest in the emergency department: a retrospective study

Table 3 Comparison of angiographic characteristics between non-survivors and survivors

	Non-survivors	Survivors	p
	n = 30	n = 7	p
Coronary angiographic findings			0.157**
Spasm	3 (10%)	-
Left main	1 (3%)	2 (29%)
One vessel	6 (20%)	-
Two vessels	11 (37%)	3 (43%)
Three vessels	9 (30%)	2 (29%)
Infarction-related artery			0.285**
Left main	8 (27%)	4 (57%)
Left anterior descending	10 (33%)	1 (14%)
Right coronary artery	12 (40%)	2 (29%)
Percutaneous coronary intervention			0.302**
Stent	19 (63%)	7 (100%)
Balloon	5 (17%)	-
Failed	2 (7%)	-
No procedure	4 (13%)	-

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.
