Left atrial assessment
| LA LGE (√%)a | LA‐vol min (mL/m2) | LA‐EF (%) | |
|---|---|---|---|
| LA‐vol min, indexed (mL /m2) | r = 0.18, P = 0.12 | ||
| LA‐EF (%) | r = −0.16, P = 0.15 | r = −0.69, P < 0.0001 | |
| MRI e′ (cm/sec) | r = −0.27, P = 0.01 | r = −0.26, P = 0.02 | r = 0.39, P = 0.0003 |
| MRI E (m/sec) | r = 0.24, P = 0.30 | r = 0.13, P = 0.58 | r = −0.26, P = 0.24 |
| MRI A (m/sec) | r = 0.23, P = 0.32 | r = −0.19, P = 0.42 | r = −0.21, P = 0.37 |
| MRI E/A | r = −0.39, P = 0.08 | r = 0.42, P = 0.06 | r = −0.06, P = 0.78 |
| MRI E/e′ | r = −0.10, P = 0.66 | r = 0.01, P = 0.95 | r = −0.47, P = 0.03 |
| Filling pressure (mmHg) | r = 0.48, P = 0.05 | r = 0.16, P = 0.51 | r = 0.26, P = 0.80 |
| PCWP (mmHg) | r = 0.81, P = 0.01 | r = 0.54, P = 0.17 | r = 0.08, P = 0.85 |
| LVEDP (mmHg) | r = 0.26, P = 0.50 | r = 0.08, P = 0.82 | r = 0.24, P = 0.82 |
Filling pressure is both PCWP and LVEDP. Volumes were indexed to body surface area. LA LGE, left atrial late gadolinium enhancement; LA‐vol min, minimum left atrial volume (atrial end‐systole); LA‐EF, left atrial ejection fraction; MRI, magnetic resonance imaging; PCWP, pulmonary capillary wedge pressure; LVEDP, left ventricular end‐diastolic pressure.
Significant correlates are highlighted with a bold font.
