Post-SPECT strategy

	CAG			Medical treatment
				Reason
	Revascularisation	Medical treatment		Small ischaemic burden	Good response to medical therapy	Risk of CAG or subsequent revascularisation considered too high
		Reason
		Revascularisation not possible	Coronary artery disease <70%
SPECT infarct only (N = 16)	2 [CABG = 1]	1	1	9 [NCD = 1, CD = 3]	1	2
SPECT infarct and ischaemia (N = 52)	15 [PCI = 2, CABG = 1]	4 [NCD = 1]	3 [PCI = 2]	13 [NCD = 1, CD = 1]	11 [CD = 6, PCI = 1]	6 [CD = 2, MI = 1]
SPECT ischaemia only (N = 28)	7 [CABG = 2, PCI = 1]	4 [MI = 1]	5 [PCI = 1]	4 [MI = 1]	4 [PCI = 1]	3 [CD = 1, MI = 1]

AARD = abnormal activation related defects, AMI = acute myocardial infarction, CABG = coronary artery bypass graft, CAG = coronary angiography, NCD = non-cardiac death, PCI = percutaneous coronary intervention, SPECT = single photon emission computed tomography
