What is a heart attack?
A heart attack, also known as myocardial infarction, is a form of acute coronary syndrome. It happens when the heart doesn’t receive enough blood.
There are three types of heart attacks:
What is STEMI
STEMI stands for ST-Segment Elevation Myocardial Infarction.
ST-Segment refers to the pattern that is seen on the ECG.
It’s a severe and common heart attack in which the coronary artery becomes completely blocked because the muscles stop getting blood
How do we differentiate between STEMI and NSTEMI?
The main difference between STEMI and Non-STEMI is the ST-segment elevation, which indicates the cardiac muscle damage limit.
ST-segment elevation usually implies that the cardiac muscle is dying due to a total blockage.
Non-STEMI heart attacks typically feature a partially blocked artery, which generally results in less damage to the heart muscle.
If the ECG doesn’t show ST-segment elevation, it’s recommended to do a troponin test as troponin level in blood indicates heart muscle damage, and it means that there is an NSTEMI.
