Cox Regression Analysis between echocardiographic parameters and outcome
events.
Univariate analysis: All the echocardiographic systolic and diastolic
function parameters assessed.
Multivariate Model 1: Parameters currently used to indicate surgery
(LVEDV, LVESV and LVEF) and conventional diastolic variables
statistically significant in the univariate model (E, E/e’ ratio, LA
volume) except SPAP because it is available only in 39 patients.
Model 2: In LA autostrain group. Significant parameters in the Model 1
(LVEDV, E/e’ ratio) and LASr.
CI, confidence interval; HR, hazard ratio; LVEDV, left ventricular
end-diastolic volume, LVESV, left ventricular end-systolic volume, LVEF,
left ventricular ejection fraction; and TR, tricuspid regurgitation.
