Comparison of all-cause deaths between HFrEF and HFpEF + HFmrEF group
| Comparison/group | HFrEF (n = 406) | HFpEF+HFmrEF (n = 566) | Total (n = 972) | p value |
|---|---|---|---|---|
| Median survival time, days | 901.00±97.26 | – | 1,236 | – |
| Age, years | 64.12±12.08 | 69.07±12.04 | 67.00±12.29 | <0.001 |
| Total all-cause mortality, n (%) | 212 (52.22) | 232 (40.99) | 444 (45.68) | 0.001 |
| All-cause mortality, n (%) | ||||
| Male | 149 (52.28) | 122 (39.10) | 271 (45.40) | 0.001 |
| Female | 63 (52.07) | 110 (43.31) | 173 (46.13) | 0.112 |
Quantitative data with a normal distribution are described as X ± S; comparisons were performed using the t test. The categorical data are described as n (%); comparisons were performed using the χ2 test.
p value <0.05 indicated statistical significance. p values compare the HFpEF + HFmrEF group with the HFrEF group.
