| Scientific title | A multicentre randomised interventional treatment trial to explore the mechanistic pathway of ischaemic preconditioning and postconditioning in the clinical settings of myocardial ischaemia-reperfusion injury |
| Study acronym | ACE - CABG/PPCI |
| Study objectives | The aim of the study is use pharmacological agents that have been shown to activate survival kinases and inhibit mPTP opening to explore the mechanistic pathway of ischaemic preconditioning and postconditioning in the clinical settings of myocardial ischaemia-reperfusion injury. Patients who are due to undergo planned cardiac surgery will be recuited to receive an interventional agent. These patients will be randomised and compared against a group of controls. Blood tests would be taken post-operatively to assess the primary end points. |
| Ethics approval(s) | The Joint UCL/UCLH Committees on the Ethics of Human Research Committee (Alpha) approved on the 23/11/2006 (ref: 06/Q0502/83) |
| Health condition(s) or problem(s) studied | Topic: Cardiovascular; Subtopic: Cardiovascular (all Subtopics); Disease: Cardiovascular |
| Intervention | 1. Intervention 1: Cyclosporin A at dose of 2.5 mg/kg; diluted in 100 ml of normal saline. Once only dose given over 30 minutes prior to surgery. 2. Intervention 2: Atorvastatin at a dose of 160 mg; given on the morning of surgery and a second dose of 160 mg repeated 24 hours later 3. Intervention 3: Erythropoietin at a dose of 50,000 IU; given as an infusion of 50 ml over 30 minutes prior to revascularisation. A second dose is repeated 24 hours later. |
| Intervention type | Other |
| Primary outcome measure(s) |
Serum cTnT and CK-MB (bloods taken before intervention and at 6, 12, 24, 48 and 72 hours post-intervention). |
| Key secondary outcome measure(s) |
1. Inotropic score: calculated using the maximum inotropic dose used on day 1 post-op |
