Pharmacological Postconditioning to Reduce Infarct Size Following Primary PCI

What this study is testing ClinicalTrials.gov NCT00835848 ↗

Description as written by the study sponsor.

Both pre- and postconditioning seem to protect cardiomyocytes during reperfusion therapy. Investigations both ex vivo and in vivo suggest that a gut derived hormone, Glucagon-Like-Peptide-1 (GLP-1), is able to reduce reperfusioninjury after myocardial ischemia. Results from our own laboratory have shown a marked reduction in infarct size when rat hearts in a Langendorf preparation were exposed to the GLP-1 analogue, exendin-4. The investigators want to investigate to what extent this effect can be translated to humans in the setting of acute STEMI treated with primary PCI when evalutaed by cardiac magnetic resonance imaging.

Treatments tested

• Exenatide Drug

  Following arrival at the catheter laboratory informed consent is obtained and the patient randomised to placebo or exenatid treatment. 25 μg Byetta (Lilly, Exenatide) and 0.1% human albumine are added to 250 ml isotonic NaCl. Infusion is started immediately at 72ml/hour for 15 min, followed by 26ml/hour to be contoinued for 6 hours.

• Saline Drug
