Heart failure classification and ejection fraction data in the 81 heart failure patients with ejection fraction available at baseline
| Ejection fraction | |||
|---|---|---|---|
| rEF EF ≤ 40% (n = 26) | Borderline pEF 40% < EF < 50% (n = 40) | pEF 50% ≥ EF (n = 15) | |
| Heart failure | |||
| Yes, NYHA Class I, n (%) | 1 (3.8) | 3 (7.5) | 8 (53.3) |
| Yes, NYHA Class II, n (%) | 25 (96.2) | 37 (92.5) | 7 (46.7) |
| No | 0 | 0 | 0 |
| Ejection fraction (%) | |||
| N | 26 | 40 | 15 |
| Mean (SD) | 37.4 (2.7) | 44.8 (2.6) | 58.1 (7. 8) |
| Median | 38.0 | 45.0 | 56.0 |
| Quartiles (25th, 75th) | 36.0, 39.0 | 42.0, 47.0 | 51.0, 60.0 |
EF, ejection fraction; HF, heart failure; NYHA, New York Heart Association; pEF, preserved ejection fraction; rEF, reduced ejection fraction; SD, standard deviation.
