What defines a STEMI?

What defines a STEMI?

Description. STEMI is defined by symptoms of myocardial ischemia accompanied by a persistent elevation of the ST segment on the electrocardiogram (ECG) and the subsequent release of biomarkers of myocardial necrosis.

What are the 5 types of MI?

Five Types of MI Will Make Up New Definition

  • A primary coronary event, such as plaque rupture or dissection.
  • A problem of oxygen supply and demand, such as coronary spasm, coronary embolism, arrhythmia, anemia, or hypotension.

What is PCI for 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.

How do you manage STEMI?

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 STEMI and Nstemi?

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.

How much elevation is needed for STEMI?

Note that 1 mm of ST elevation in 2 contiguous leads is required to diagnose STEMI, however there are two major exceptions. Anterior STEMI requires 2 mm of ST elevation in V2 and V3 in men > 40 years old according to the ACC/AHA definition.

How do you treat a STEMI?

The priority in treating a STEMI heart attack is to open the artery quickly, saving as much heart muscle as possible. Treatment options include percutaneous coronary intervention (PCI), a term that encompasses both angioplasty and stenting; clot-busting medication; and coronary artery bypass graft surgery (CABG).
