THERE ARE TWO TYPES
- ST ELEVATED MI
- NON ST ELEVATED MI
It’s one type of classification
Can anyone write about the MI and angina ?
What’s the difference between them

Myocardial infarction - A heart attacks occurs when the blood flow to the heart is blocked. Causing damage to heart muscle.
Angina - due to less supply of blood to heart muscle,there is symptoms of pain…this chest pain is called angina.
Conclusion - we can say that angina is a symptom of myocardial infarction.

The ecg changes occurs in the qrs complex waves such as
T wave inversion
Pathological q waves
ST segment elevation.
Non ST segment elevation
Reciprocal of ST wave.
T wave inversion
Furthermore,
Pathological Q wave.

St segment elevation in a particular lead defines the infraction in that wall
Eg:- st elevation in 2,3,avf :- inferior wall MI.
Deep Q wave:- defines the stage of MI
For a heart attack, ST elevation on ECG is key. Immediately, we’d focus on restoring blood flow, usually with emergency angioplasty, plus pain relief and oxygen.
Ecg changes are of 2 types : stemi and nstemi
Immediate treatment involves: double dose aspirin/ecospirin(175mg) and isordil ( nitroglycerin). These drugs must be present in ur pockets as emergency drugs
ECG shows ST elevation (STEMI), ST depression or T wave inversion (NSTEMI).
Immediate steps: MONA-BASH—Morphine, Oxygen, Nitrates, Aspirin, Beta-blockers, Anticoagulants, Statins. Reperfusion via PCI or fibrinolysis.
