Non-invasive evaluation of myocardial reperfusion by transthoracic Doppler echocardiography and single-photon emission computed tomography in patients with anterior acute myocardial infarction

Table 4 The relationship between CFR, the final infarct size (TPD) and myocardial viability at follow-up

		TPD yes	≤15% no	Positive predictive value	Negative predictive value	Sensitivity	Specificity
CFR ≥	yes	17	2	0,89	0,80	0,77	0,91
1.75	no	5	20
		Myocardial	viability
		yes	no
CFR ≥	yes	10	9	0,52	0,92	0,83	0,72
1.75	no	2	23
		Myocardial	viability
		yes	no
TPD ≤	yes	11	11	0,50	0,95	0,92	0,66
15%	no	1	21

CFR - coronary flow reserve; TPD - total perfusion defect; the difference between WMSI (at rest) during AMI and WMSI (at rest) at follow-up ≥ 0.25 indicates the myocardial viability
