− = TBR <1; + = TBR 1.00 to 1.99; ++ = TBR 2.0 to 2.99; +++ = TBR 3.0 to 3.99; ++++ = TBR of 4.0 or greater.

CP = chest pain; ECG = electrocardiogram; LAD = left anterior descending coronary artery; LCx = left circumflex coronary artery; MI = myocardial infarction; NSTEMI = non–ST-segment elevation myocardial infarction; PCI = percutaneous coronary infusion; RCA = right coronary artery; STEMI = ST-segment elevation myocardial infarction; TBR = target-to-background ratio; UAP = unstable angina pectoris; other abbreviations as in Table 1.
