Figure 2 Increased videointensity and left ventricular (LV) volumes (mean value ± SEM) in the "primary/rescue" percutaneous transluminal coronary angioplasty (PTCA) group (left graph) and in the "late" PTCA group (right graph). A trend for a beneficial effect from increased videointensity was evident in all subgroups, but it reached statistical significance only for the diastolic volume in the "primary/rescue" PTCA group. Ventricular volumes were, on the average, larger in the "late" PTCA group.
