Categorical parameters are described by absolute number and percentage of patients in given category; continuous variables are described by median (5th; 95th percentile).
2
Overall statistical significance of differences among groups is based on Mann-Whitney test for continuous variables and ML chi-square test for categorical variables,
3
Creatinine clearance was estimated according to MDRD formula;
*
statistically significant.
BMI – Body mass index, TIA – Transitory ischemic attack, EF LV – Ejection fraction of left ventricle, PA systolic – Pulmonary artery systolic pressure, AVA – Aortic valve area.
