Description

Myocardial Infarction (MI) also referred to as a “heart attack” is caused by a partial or total interruption of blood supply to the myocardium. Myocardial infarction can either be “silent” or go undetected, or it can be a catastrophic occurrence that causes hemodynamic deterioration and sudden death. The primary cause of death in the United States and the underlying cause of the majority of myocardial infarctions is coronary artery disease. Coronary artery blockage deprives the myocardium of oxygen. Myocardial necrosis and cell death can occur if the myocardium is continuously deprived of oxygen. Patients may complain of chest tightness or discomfort that radiates to their neck, jaw, shoulder, or arm. Myocardial ischemia may also be indicated by an elevated cardiac troponin level and abnormalities in the ECG in addition to the history and physical examination. The pathogenesis, assessment, and therapy of myocardial infarction are discussed in this practice, which also emphasizes the importance of the interprofessional team in enhancing patient care.

Acute or persistent myocardial ischemia can lead to myocardial infarction. Myocardial ischemia differs slightly from myocardial hypoxia in that it causes cellular damage above and beyond that caused by hypoxia because it causes a stasis of metabolic waste products in addition to a lack of oxygen delivery. Acute or chronic myocardial infarction is a pathologic diagnosis that is characterized by the loss of normal cardiac myocyte structure (i.e., myocytolysis, coagulative necrosis, inflammatory cell infiltration, and fibrosis). Many factors can induce myocardial infarction, which is a major factor in cardiovascular disease and mortality in people. Myocardial infarction in humans is mostly caused by atherosclerosis and coronary artery disease, both of which are rather uncommon in the veterinary patient population. The probability of irreversible myocardial ischemia from any one coronary artery obstruction may be lower in dogs because of the relatively large collateral circulation of the coronary arterial supply.

Preferably, a medical professional should assess you for risk factors for heart attacks during routine exams. In an emergency situation, a heart attack is frequently identified. Heart attack diagnosis tests include the following:

Electrocardiogram (ECG) (ECG or EKG)

This initial test for heart attack diagnosis records electrical signals as they move through the heart. Electrodes with sticky patches are affixed to the chest, and sometimes the arms and legs. Waves that are displayed on a monitor or printed on paper are used to record signals. If you are having or have had a heart attack, an ECG can detect it.

Blood tests

Following cardiac damage after the heart attack, some heart proteins gradually leak into the circulation. These proteins can be examined via blood testing

A chest X-ray

The size and condition of the heart and lungs can be seen on a chest X-ray.

Echocardiogram

Ultrasound creates images of the beating heart. This test can demonstrate how the heart and heart valves function. Your heart's damage can be determined with the aid of an echocardiography.

Coronary angioplasty (angiogram)

In order to reach the heart, a long, thin tube (catheter) is placed into an artery, typically in the leg. In order to improve the visibility of the arteries on test images, dye flows via the catheter.

Heart CT or MRI scans

Images of the heart and chest are produced by these following tests. X-rays are used in cardiac CT scans. A magnetic field and radio waves are used in cardiac MRI to produce images of your heart.
