Explain the significance of Myocardial Infraction
A myocardial infarction (MI), sometimes known as a "heart attack," occurs when blood supply to a region of the myocardium is reduced or completely stopped.
- Myocardial infarction can be "silent" and go unnoticed, or it can be a life-threatening event resulting in hemodynamic decline and rapid death.
- The vast majority of myocardial infarctions are caused by underlying coronary artery disease, which is the leading cause of mortality in the world.
- The myocardium is deprived of oxygen due to coronary artery blockage. Prolonged oxygen deprivation of the heart can result in myocardial cell death and necrosis.
Patients may complain of chest pain or pressure that spreads to the neck, jaw, shoulder, or arm.
Myocardial ischemia may be linked with ECG abnormalities and increased biochemical markers such as cardiac troponins in addition to the history and physical exam.
