Figure 1 Cardiac function over time after heart transplantation. There were no statistically significantly differences in left ventricular ejection fraction at 1, 6, and 12 months after heart transplantation. At 3 months after heart transplantation, left ventricular ejection fraction of the RRT group (59.5±2.1%, mean±SD) was significantly lower than that of the non-RRT group (64.2±0.6%, mean±SD) (p=0.008). Left ventricular ejection fraction at 1 month was 61.5±3.9% (mean±SD) in the RRT group and 64.2±4.5% (mean±SD) in the non-RRT group. At 6 months, it was 61.8±3.2% (mean±SD) in the RRT group and 63.5±6.3% (mean±SD) in the non-RRT group. At 12 months, it was 62.5±4.2% (mean±SD) in the RRT group and 52.0±15.0% (mean±SD) in the non-RRT group. P values were calculated using the t test. * P<0.05 was considered statistical significance.
