Figure 4 Kaplan-Meier survival curves (considering cardiac death) in patients stratified according to DET test results in relation to the pharmacologic dose achieved. Low-dose positivity was considered to have occurred during the dose of 0.56 mg/kg in 4 min of dipyridamole or during the following 4 min or at the dose 20 µg/kg/min of dobutamine (high-dose positivity vs. low-dose positivity, p = 0.0000).
