| Variables | Level of E/e' |
P for difference | ||
|---|---|---|---|---|
| <8 [N=993, 35%] | 8-15 [N=1444, 51%] | ≥15 [N=378, 13%] | ||
| Outcomes at 3 months after stroke* | ||||
| mRS score 2-6 | 433 (43%) | 677 (45%) | 254 (63%) | <0.01 |
| Recurrent stroke | 51 (5%) | 99 (7%) | 30 (7%) | 0.13 |
| Composite vascular events | 60 (6%) | 104 (7%) | 34 (8%) | 0.21 |
| Outcomes at 1 year after stroke† | ||||
| mRS score 2-6 | 353 (38%) | 521 (40%) | 201 (58%) | < 0.01 |
| Recurrent stroke | 67 (7%) | 116 (9%) | 42 (12%) | 0.03 |
| Composite vascular events | 79 (8%) | 129 (10%) | 56 (16%) | < 0.01 |
mRS, modified Rankin Scale; composite vascular events include recurrent stroke, myocardial infarction and vascular death after the index stroke; E, peak early transmitral filling velocities during early diastole; e’, mean early velocities at septal mitral annuli on Tissue Doppler image.
*
Outcomes at 3 months after stroke were based on 2,812 cases for the mRS score and 2,827 cases for recurrent stroke and composite vascular events;
†
Outcomes at 1 year after stroke were based on 2,511 cases for the mRS score and 2,552 cases for recurrent stroke and composite vascular events.
