Why the study?
It was unknown whether insulin-like growth factor-binding protein 5 (IGFBP5) is involved in myocardial repair following myocardial infarction.
Population
Mice with MI and neonatal rat cardiomyocytes exposed to oxygen-glucose deprivation
Comparison
Heart-specific IGFBP5 knockdown or regulation vs controls
Design
Preclinical animal and in vitro mechanistic study

No immediate clinical role in MI; leaves open IGFBP5 as a preclinical target for post-infarct repair.
IGFBP5 knockdown improves cardiomyocyte survival and functional recovery after myocardial infarction in preclinical models, suggesting it may be a novel therapeutic target for ischemic injury.
