Figure 4 Effect of high-dose folate on peak flow ratio. The ratio for peak myocardial blood flow, in abnormal relative to normal segments, is shown for each patient. Group mean data are depicted by the thick line. Folate increased the ratio of flow in abnormal segments relative to normal segments (0.54 ± 0.17 vs. 0.75 ± 0.24, mean ± SD, placebo vs. folate, p < 0.01).
