Trained professional should assess ECG; ST-segment elevation myocardial infarction (STEMI)
What is STEMI and non STEMI?
STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria..NSTEMI usually results from severe coronary artery narrowing, transient occlusion, or microembolization of thrombus and/or atheromatous material.
What is STEMI management?
Initial medical therapy during STEMI consists of oxygen administration, antiplatelet therapy (aspirin, thienopyridines and glycoprotein IIb/IIIa inhibitors), anticoagulation, anginal pain relief with nitrates and morphine, and beta-blockade.
What is the difference between a STEMI and a non STEMI?
If there is a pattern known as ST-elevation on the EKG, this is called a STEMI, short for ST elevation myocardial infarction. If there is elevation of the blood markers suggesting heart damage, but no ST elevation seen on the EKG tracing, this is known as a NSTEMI.
What is the primary goal of acute coronary syndrome algorithm?
Initial therapy for ACS should focus on stabilizing the patient’s condition, relieving ischemic pain, and providing antithrombotic therapy to reduce myocardial damage and prevent further ischemia.
What causes stemi?
STEMI: Most commonly caused by an acute occlusion of a coronary blood vessel secondary to acute plaque rupture and thrombosis. However, cocaine use can also cause a STEMI due to coronary vasospasm, rather than occlusion with thrombosis.
What is troponin protein?
Troponin is a type of protein found in the muscles of your heart. Troponin isn’t normally found in the blood. When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood.
What is PCI STEMI?
Primary percutaneous coronary intervention (PCI) refers to the strategy of taking a patient who presents with STEMI directly to the cardiac catheterization laboratory to undergo mechanical revascularization using balloon angioplasty, coronary stents, aspiration thrombectomy, and other measures.
Why is heparin used in STEMI?
The most important is that the heparin-antithrombin complex cannot bind or inactivate thrombin bound within a clot . Such clot-bound thrombin acts as an important thrombogenic stimulus at a site of coronary thrombosis, particularly after clot disruption by fibrinolytic agents .
What is acute STEMI?
An acute ST-elevation myocardial infarction (STEMI) is an event in which transmural myocardial ischemia results in myocardial injury or necrosis.  The current 2018 clinical definition of myocardial infarction (MI) requires the confirmation of the myocardial ischemic injury with abnormal cardiac biomarkers.
What is Inferolateral STEMI?
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
What are the 3 cardiac enzymes?
Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase.
What are the troponin levels?
For example, the normal range for troponin I is between 0 and 0.04 ng/mL but for high-sensitivity cardiac troponin (hs-cTn) normal values are below 14ng/L. Other types of heart injury may cause a rise in troponin levels.
What is the most common symptom of myocardial ischemia and infarction?
When they do occur, the most common is chest pressure or pain, typically on the left side of the body (angina pectoris). Other signs and symptoms — which might be experienced more commonly by women, older people and people with diabetes — include: Neck or jaw pain.
In what order should MONA be done?
In a medical setting, when treating a patient with Myocardial Infarction, it used to be recommended to give: Oxygen first, then nitrates, then aspirin, then morphine.
What is PCI in ACLS?
Percutaneous coronary intervention (PCI) can restore flow of blood into the myocardium in more than 90% of patients if performed by a skilled provider at a proficient PCI facility with a “door-to-balloon” time of less than 90 minutes.
