p-value (P-1) |
p-value (P-2) |
|---|---|---|---|---|---|
| LVEDP, mm Hg | 17 (13–24) | 20 (16–26) | 19 (14–24) | 0.01 | 0.10 |
| Transaortic mean gradient, mm Hg | 41 (31–54) | 43 (30–57) | 44 (34–55) | 0.24 | 0.85 |
| Transaortic peak gradient, mm Hg | 46 (31–61) | 51 (34–67) | 50 (37–67) | 0.07 | 0.63 |
| Aortic pulse pressure, mm Hg | 83 ± 28 | 77 ± 26 | 75 ± 27 | 0.01 | 0.56 |
| Heart rate adjusted ARi | 45 ± 15 | 42 ± 15 | 40 ± 15 | 0.03 | 0.32 |
Values are means ± SD or medians (25th–75th percentile). p-values of P‑1 and P‑2 represent the statistical significance of the pairwise comparison of pre-COVID-19 versus COVID-19 year 1 and COVID-19 year 1 versus COVID-19 year 2, respectively
