Outcomes
Primary Outcomes
Correlation between systemic vascular resistance and aortic augmentation index
Time Frame: One year
Identity of cardiac output given by the PiCCO monitor and cardiac output given by the Arteriograph
Time Frame: One year
Number and degree of hypotensive episodes predicted by preoperative values of pulse wave velocity.
Time Frame: One year
The investigators will examine if high values of pulse wave velocity correlate with the frequency and severity of hypotensive episodes under anaesthesia.
Secondary Outcomes
No secondary outcomes reported
