Figure 2 Changes in time velocity integral of the diastolic coronary flow (Dtvi) and Dtvi x heart rate (HR) after food intake in controls (upper panel) and in patients (lower panel). Dtvi and Dtvi x HR increased in controls after food intake. In patients, Dtvi and Dtvi x HR decreased after food intake. *p < 0.05, p < 0.005 compared with the fasting state by the Wilcoxon signed rank test.
