Correlation of regional myocardial blood flow and function with myocardial infarct size during acute myocardial ischemia in the conscious pig.

abstract：BACKGROUND:Although beta-adrenergic receptor (AR) blockade therapy is beneficial in the treatment of heart failure, little is known regarding the transcriptional mechanisms underlying this salutary action.
