Figure 3  .

Scatterplot showing the distribution of myocardial blood flow (uncorrected and corrected for the rate-pressure product) before revascularisation in the hibernating segments. The thresholds of 0.55 and 0.45 ml/min/g represent the mean value minus 2 SDs of myocardial blood flow in control segments (uncorrected and corrected for the rate-pressure product). MBF, myocardial blood flow uncorrected for the rate-pressure product; MBFcorr, myocardial blood flow corrected for the rate-pressure product.
