The population was divided into MAP quartiles. The mean systolic BP, diastolic BP, and MAP in the entire population were 149 \u00b1 25, 68 \u00b1 11, and 98 \u00b1 14 mmHg. Patients in the lowest MAP quartile had the lowest left ventricular ejection fraction (LVEF), systemic vascular resistance, and valvulo-arterial impedance, whereas there were no significant differences in mean right atrial pressure, mean pulmonary artery wedge pressure, pulmonary vascular resistance, and stroke volume index across MAP quartiles. However, left ventricular stroke work index (LVSWI) was lowest in patients in the lowest and highest in those in the highest MAP quartile. After a median (interquartile range) post-AVR follow-up of 3.7 (2.6\u20135.2) years, mortality was highest in patients in the lowest MAP quartile [hazard ratio 3.08 (95% confidence interval 1.21\u20137.83); P = 0.02 for lowest versus highest quartile]. In the multivariate analysis, lower MAP [hazard ratio 0.78 (95% confidence interval 0.62\u20130.99) per 10 mmHg increase; P = 0.04], higher mean right atrial pressure and lower LVEF were independent

patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular
