Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory responses, and cell death. Characteristic changes in heart electrical activity (such as ST‐segment elevation) and tissue alterations (including scarring and immune cell accumulation) further validate its relevance for cardiovascular research. Physical assessments include the heart‐to‐body weight ratio and electrocardiogram abnormalities. Blood tests detect elevated levels of specific proteins that indicate heart muscle injury, such as cardiac troponins and creatine kinase‐MB. Measurements of antioxidant enzymes and oxidative damage markers help assess stress levels in heart tissue. Heart function is evaluated through blood pressure monitoring and ventricular pressure measurements. Inflammatory molecules in the bloodstream reveal the body's response to heart damage. Microscopic examination of heart tissue shows structural changes, including cell death, scar formation, and immune cell invasion. By combining these different types of measurements, researchers can thoroughly analyze heart damage in this experimental model. This comprehensive approach supports the discovery of new heart‐protective treatments and improves our understanding of heart attack mechanisms, benefiting both laboratory studies and patient care.
