What is the pathophysiology of NSTEMI?

What is the pathophysiology of NSTEMI?

UA/NSTEMI most often represents severe coronary artery narrowing or acute atherosclerotic plaque rupture/erosion and superimposed thrombus formation. Alternatively, it may also be due to progressive mechanical obstruction from advancing atherosclerotic disease, in-stent restenosis, or bypass graft disease.

What is NSTEMI myocardial infarction?

Non-ST-elevation myocardial infarction (NSTEMI) is a type of [“heart attack”: link to new heart attack copy] involving partial blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscle.

How do you diagnose NSTEMI?

NSTEMI heart attacks are diagnosed through the combination of a blood test and an electrocardiogram (ECG). Doctors use the blood test to look for indications of NSTEMI, such as higher than usual levels of creatine kinase-myocardial band (CK-MB), troponin I, and troponin T.

What is the difference between an NSTEMI and a 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 causes a NSTEMI?

The etiology of NSTEMI varies as there are several potential causes. These include tobacco abuse, lack of physical activity, high blood pressure, high cholesterol, diabetes, obesity, and family history.

Is NSTEMI serious?

A non-ST segment elevation myocardial infarction, also called an NSTEMI or a non-STEMI, is a type of heart attack. While it’s less damaging to your heart than a STEMI, it’s still a serious condition that needs immediate diagnosis and treatment.

How do you manage an NSTEMI?

Unfractionated heparin with bolus dosing and a continuous infusion is commonly used, with most institutions having protocols available. Other strategies may include the use of enoxaparin, bivalirudin, fondaparinux, and dual antiplatelet therapies. Fibrinolytic therapies should not be used in NSTEMI.

How long can a NSTEMI last?

The “typical” presentation of NSTEMI is a pressure-like substernal pain, occurring at rest or with minimal exertion. The pain generally lasts more than 10 minutes and may radiate to either arm, the neck, or the jaw.

What is the difference between NSTEMI and STEMI?

NSTEMI has a depressed ST segment while STEMI has an elevated ST segment that is not relieved by nitroglycerine. 4. NSTEMI is a partially blocked artery while STEMI happens when the whole artery is blocked causing a part of the heart to die off.

What does STEMI mean medically?

A STEMI is a full-blown heart attack caused by the complete blockage of a heart artery. A STEMI heart attack, like a Widow Maker, is taken very seriously and is a medical emergency that needs immediate attention. For this reason its often called a “CODE STEMI” or a “STEMI alert.” STEMI stands for ST elevation…

What does STEMI stand for medical?

STEMI stands for ST-segment Elevation Myocardial Infarction. The ST in this case doesn’t stand for anything; it refers to the part of the EKG tracing that is higher than usual (elevated). Patients with STEMI may benefit from treatment to restore flow to the heart muscle.
