Figure 2 Diastolic coronary flow reserve in patients with left anterior descending coronary artery disease before and early after stent implantation (p < 0.0001). Confidence intervals (95%) of the average value obtained in 23 consecutive control subjects provide a direct comparison to visually estimate how the variable distributes before and after the procedure. There is a clear overlap between the post-stent reserve distribution and average values measured in control subjects, indicating a high probability of normalized reserve after the procedure. Conversely, values measured before the procedure are far from normal in the large majority of patients.
