Values are shown as odd ratio (95% CI), values indicate statistically significant values; it is significant at the 0.05 level. PWV: pulse wave velocity; AVR: aortic valve replacement; CABG: coronary artery bypass grafting; CI: confidence interval; AVA: aortic valve area; LV: left ventricular; NYHA: New York Heart Association
