Remote ischaemic preconditioning to protect the myocardium during abdominal aortic aneurysm repair

INTERVENTION: Randomised controlled trial: 1. Abdominal aortic aneurysm repair alone 2. Abdominal aortic aneurysm repair with intermittent cross clamping/perfusion of common iliac artery Postoperatively, patients will have cardiac troponin and creatine kinase MB (CKMB) recorded on days 1, 3 and 7. Holter monitoring is to be continued until 48 h post operation. CONDITION: Aortic aneurysm repair ; Circulatory System ; Aortic aneurysm and dissection PRIMARY OUTCOME: A reduction in myocardial damage as assessed by serum measurement of cardiac troponin and Holter electrocardiogram. SECONDARY OUTCOME: Not provided at time of registration INCLUSION CRITERIA: 72 Subjects aged 18‐90.
