Relation from a linear regression model between change over baseline in regional left ventricular function (the response, or y, variable, assessed by five segment and 20 segment models) and a 0.1 unit change in PDCF (the explanatory, or x, variable)
| Regional wall motion | Change in regional wall motion (95% CI) for a 0.1 unit increase in PDCF | p Value |
|---|---|---|
| Anterobasal (AB), anterolateral (AL), and apical (AP) segments are from the left anterior descending coronary artery (LAD) territory in the five segment model; diaphragmatic (DM), posterobasal (PB), and AP segments are from the left circumflex (LCX)/right coronary artery (RCA) territories. Note: the AP segment overlaps the two territories. Slager segments 1–10 represent LAD territory and segments 11–20 represent LCX/RCA territory. | ||
