Implication

Randomized trial investigates early angiogenesis factors in ischemic heart tissue, suggesting critical adaptation mechanisms.

Key Points

The study aims to investigate the early molecular responses of the myocardium to ischemia and infarction by examining the expression of HIF-1alpha and VEGF.
Analysis of ventricular-biopsy specimens from 37 patients undergoing coronary bypass surgery.
Utilization of reverse-transcriptase polymerase chain reaction to assess HIF-1alpha and VEGF mRNA expression.
Immunohistochemical analysis to locate HIF-1alpha and VEGF proteins in tissue samples.
HIF-1alpha mRNA detected in specimens with acute ischemia (<48 hours before surgery) or early infarction (<24 hours before surgery).
VEGF transcripts found in specimens with acute ischemia or evolving infarction (24 to 120 hours before surgery).
No detectable HIF-1alpha or VEGF mRNA in patients with normal ventricles or historical infarction.
