Cardiac function in patients with treated hypertension during aortic aneurysm repair

Anesthesia for Open Abdominal Aortic Aneurysm Repair

“…61 Shuetz et al have shown that the treated hypertensive patients had significant increase in mean arterial pressure (MAP), PCWP, and mean peak A/peak E velocity after cross-clamping, compared to normotensive controls, but these disturbances normalized after unclamping and the intraoperative management did not differ in both groups. 62 Fayed et al reported acute diastolic dysfunction after high aortic clamping in six of nine patients with normal E/A ratios before clamping in thoracoabdominal surgery and three of those patients developed myocardial infarction. 63 The level of aortic cross clamp again has an influence on diastolic dysfunction and its effect on outcome.…”
