Introduction/Etiology and Pathophysiology of STEMIMyocardial infarction is a serious and life-threatening emergency. Prompt assessment and diagnosis are imperative to properly treat a patient. It is essential that the nurse and health care team understand the diagnostic procedures, laboratory tests, and treatments that can save the life of a patient with chest pain. Myocardial infarctions can occur in different parts of the heart and may receive different classifications depending on the symptoms presented. The most serious type of myocardial infarction is classified as ST elevation myocardial infarction or STEMI. A STEMI is a type of heart attack that involves an ST-elevation myocardial infarction (CDC, 2010). A STEMI is the traditional manifestation and was historically used to diagnose myocardial infarction (Ignatavicius & Workman, 2013, p. 829). We now know that not all myocardial infarction patients will present this way (Ignatavicius & Workman, 2013, p. 829). According to Ignatavicius and Workman (2013), patients with STEMI typically have ST-segment elevation in two contiguous leads on a 12-lead ECG. A STEMI indicates myocardial infarction or necrosis and requires immediate treatment (Ignatavicius & Workman, 2013, p. 829). According to the American Heart Association (AHA) (2010), STEMI accounts for 25–40% of the 683,000 U.S. patients diagnosed with acute coronary syndrome each year. A myocardial infarction occurs when myocardial tissue is abruptly and severely deprived of oxygen (Ignatavicius and Workman, 2013, p. Due to this rapid decrease in blood flow, ischemia develops, which can then lead to damage and myocardial necrosis... middle of paper ...... hey, it may require surgical management, which could require another APTC or CABG. the nurse will need to monitor their patient for postoperative complications. ConclusionIn conclusion, coronary health is of utmost importance. The prevalence of coronary heart disease and acute coronary syndromes is alarming. are essential to promote cardiac health and reduce the risk of MI. An acute myocardial event such as a STEMI can be seriously life-threatening. Prompt diagnosis and treatment are imperative to provide the best chance of reperfusion to the myocardial muscle. to restore oxygen and blood flow to reduce injuries and complications. It is essential that the nurse is informed about the signs, symptoms, diagnosis and treatment of STEMI to help achieve the best outcome for the patient..
