STEMI vs. NSTEMI

ST-segment elevation myocardial infarction (STEMI) involves a complete blockage of a coronary artery, causing severe pain, while non-ST elevation myocardial infarction (NSTEMI) involves a partial blockage, resulting in less severe pain.

STEMI ECG Change

A change in the ECG that is consistent with a ST-segment elevation myocardial infarction (STEMI). This includes ST segment elevation in leads facing the infarcted area or a new left bundle branch block (LBBB).

What is a STEMI?

An ST-segment elevation myocardial infarction, or STEMI, is a type of heart attack where a complete blockage of a coronary artery causes significant damage to the heart muscle. This damage is evident on the ECG by an elevated ST segment, which is a specific pattern of electrical activity in the heart.

Signup and view all the flashcards

NSTEMI ECG Changes

In contrast to STEMI, a non-ST elevation myocardial infarction (NSTEMI) shows different ECG changes including ST-segment depression and deep T wave inversion. NSTEMI involves partial blockage of a coronary artery, leading to less extensive damage to the heart.

Cardiac Enzymes in MI

When the heart muscle is damaged (like in a heart attack), specific enzymes are released into the bloodstream. One of these is Cardiac troponin, considered the gold standard for diagnosing MI because it is more sensitive and specific than older enzymes.

Signup and view all the flashcards

Why is Troponin Important?

Troponin levels are measured to confirm a diagnosis of acute MI. This test is done at the initial assessment and then again 10-12 hours later because troponin is released gradually. The levels peak around 6-12 hours after the onset of chest pain.

3 TIMI Risk Factors

The Thrombolysis in Myocardial Infarction (TIMI) risk score helps assess the risk of complications in patients with acute coronary syndromes. It considers 3 factors: age, prior coronary artery bypass graft (CABG) surgery, and symptoms of chest pain at rest or with minimal exertion.

ECG in Suspected ACS

In suspected acute coronary syndromes (ACS), a resting 12-lead ECG should be performed immediately. This helps doctors determine the type of heart attack (STEMI or NSTEMI) and guide treatment.
