Key result
Computerized exercise ECG criteria of >1/3 mm ST depression in lead I and/or >2.0 mm in chest leads identified critical coronary lesions with 85% sensitivity and 67% specificity.

These criteria may aid noninvasive lesion detection in severe angina; cross-sectional data leave open need for prospective validation.
Observational (n=85)
Does computerized exercise ECG testing accurately identify critical coronary lesions in patients with severe angina?
Effect estimate: Sensitivity 85%, Specificity 67%, Predictive value 83%
Specific computerized exercise ECG ST depression criteria offer high sensitivity and positive predictive value for detecting critical coronary lesions in patients with severe angina.
ck et al. (2008) conducted an observational in Severe angina (n=85). Computerized exercise ECG was evaluated on Lesions in the main stem and/or proximal LAD and/or three-vessel disease (Sensitivity 85%, Specificity 67%, Predictive value 83%). Computerized exercise ECG criteria of >1/3 mm ST depression in lead I and/or >2.0 mm in chest leads identified critical coronary lesions with 85% sensitivity and 67% specificity.
