This protocol describes the porcine myocardial infarction (MI) model using a 90 min closed-chest coronary balloon occlusion of the left anterior descending artery (LAD), followed by reperfusion. Furthermore, the protocol for several outcome parameters, such as cardiac function, hemodynamics, microvascular resistance, and infarct size, are also presented.

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.
FAQs
The affected cortical territory can be related to the function that becomes impaired. Findings involving movement, sensation, language, vision, or cognition provide clinical clues about which cortical functions may be disrupted. This relationship helps clinicians interpret neurological deficits alongside imaging rather than treating each symptom as an isolated abnormality.
Comparing examination findings with the imaged location and extent of injury strengthens interpretation of the event. The comparison can support stroke diagnosis, help distinguish cortical ischemic injury from other causes of neurological dysfunction, and provide information relevant to prognosis. It also creates a consistent basis for following changes over time.
An arterial blockage limits delivery of oxygen and glucose to the affected cortex. The resulting energy failure initiates neuronal injury, which can impair the functions served by that region. Recognizing this mechanism explains why the clinical assessment focuses on both the neurological consequences and the corresponding evidence of cortical damage on brain imaging.
The assessment combines clinical evaluation of neurological deficits with brain imaging. Clinicians examine the pattern of impaired movement, sensation, language, vision, or cognition, then correlate those findings with the identified infarct, its location, and its extent. This integrated approach provides more useful information than relying on symptoms or imaging findings alone.
By identifying the affected cortical region and estimating the extent of injury, the assessment supports timely stroke diagnosis and selection of appropriate management. It also helps clinicians estimate likely neurological consequences and prognosis. The information therefore links diagnostic interpretation with immediate care planning rather than serving only as a description of the lesion.
Repeated clinical and imaging evaluation provides a framework for monitoring neurological recovery after cortical injury. Changes in movement, sensation, language, vision, or cognition can be considered alongside the known infarct. In research, this framework helps investigators study how cortical damage relates to long-term neurological outcomes and differences in recovery.
