Is there a role for ischemia detection after an acute myocardial infarction?

Table 1 Main differences between the invasive vs conservative treatment in unstable coronary syndromes, randomized intervention trial of unstable angina 3 and fast revascularization during instability in coronary artery disease studies

	FRISC-II	RITA-3	ICTUS
Year	1999	2002	2005
Inclusion criteria: Raised troponin	No	No	Yes
Functional imaging in the conservative arm	-	No (exercise ECG testing)	Yes (exercise with MIBI-SPECT)
Interventionism in the conservative arm	7%	16%	53%
Stents, invasive arm	61%	88%	88%

ICTUS: Invasive vs conservative treatment in unstable coronary syndromes; RITA-3: Randomized intervention trial of unstable angina 3; FRISC-II: Fast revascularization during instability in coronary artery disease; ECG: Electrocardiography.
