Left ventricular function and cardiovascular events following adjuvant therapy with adenosine in acute myocardial infarction treated with thrombolysis, results of the ATTenuation by Adenosine of Cardiac Complications (ATTACC) study.

Background: Reperfusion therapy for acute myocardial infarction (AMI) reduces mortality but is also associated with reperfusion injury. The present study tested the hypothesis that adjuvant therapy with a low anti-inflammatory dose of adenosine might prevent reperfusion injury and preserve left ventricular function.

Methods: Six hundred and eight patients with ST-elevation AMI were randomised to receive infusions of adenosine (10 microg x kg(-1) x min(-1)) or placebo (saline) to be started with thrombolysis and maintained for 6 h.
