The post-mortem assessment of myocardial infarction (MI) in rodents is based on quantification of the infarct on stained heart sections. We describe an accurate method to quantify the infarct size using systematic sampling of harvested rat hearts from base to apex and image analyses of trichrome-stained histological sections.

This protocol describes a highly reproducible model of cardiac regeneration by surgical induction of myocardial infarction in the left ventricle of postnatal day 1 mice. The method involves induction of hypothermic anesthesia and ligation of the left anterior descending coronary artery.
FAQs
The comparison provides an internal structural reference for recognizing ischemic injury. Stains can distinguish damaged or necrotic regions from tissue that remains preserved, allowing researchers to identify the distribution and boundaries of injury within a section. This contrast supports more consistent interpretation of microscopic findings and helps relate visible tissue disruption to the overall extent of infarction.
Area and volume describe the extent of injury at different levels. Image analysis can quantify the affected region within individual tissue sections as area, while volume represents the three-dimensional burden of injury across tissue. Reporting either measurement helps researchers compare disease models or interventions, provided the chosen metric matches the tissue assessment being performed.
A numerical infarct measurement shows how much tissue is affected, while microscopic examination reveals what that injury looks like. Cellular changes and disruption of tissue architecture provide structural context for the measured region. Together, these observations connect the extent of ischemic damage with the underlying changes visible in the tissue, supporting a fuller assessment of injury.
The workflow begins by fixing the tissue and preparing sections for microscopic examination. Researchers then apply stains that differentiate damaged or necrotic regions from preserved tissue. Microscopy provides the visual assessment, and image analysis is used to quantify infarct area or volume. This sequence combines tissue preparation, structural visualization, and measurement in one analytical process.
Stains make differences between damaged or necrotic tissue and preserved tissue more apparent under microscopy. By creating visual contrast, they help researchers identify which regions contribute to the infarct measurement. Their role is therefore analytical rather than merely descriptive: staining supports recognition of injury patterns and provides the basis for subsequent image-based quantification.
This analysis is useful when researchers need structural evidence of ischemic injury in disease models or when evaluating a treatment. It can show both the extent of tissue damage and associated cellular or architectural changes. Comparing these findings after an intervention helps assess whether the treatment alters the observed tissue injury, making the method relevant to therapeutic research.
