Features of cardiac structure and function associated with higher CHADS2 scores as a measure of stroke risk from forward stepwise multivariate logistic regression
| Characteristic | Odds ratio | 95% CI | P-value |
|---|---|---|---|
| E/e′ avg (per 4.7) | 1.24 | 1.09–1.37 | 0.001 |
| LAVI, mL/m2 (per 11.2) | 1.22 | 1.06–1.34 | 0.005 |
| Abnormal LV geometry | 1.16 | 1.01–1.39 | 0.035 |
LAVI, left atrial volume index; LV, left ventricular; abnormal LV geometry defined as concentric remodelling or hypertrophy.
Covariates entered into model: heart rate, systolic BP, diastolic BP, rhythm at the time of echocardiography, LVEF, LV end-diastolic volume, LV end-systolic volume, LV end-diastolic diameter, LV end-systolic diameter, LV wall thickness, LV mass index, LV geometry, LA width, LA volume index, LA minimum volume, LA emptying fraction, LA expansion index, E-wave velocity, E-wave deceleration time, tissue Doppler imaging E′ velocity, LV filling pressures (E/e′), and mitral regurgitation.
Model characteristics: log likelihood = −860; χ2 = 25.7, P < 0.001.
