Myocardial infarction Flashcards
1
Q
define an MI
A
blockage of blood flow to the heart muscle leading to ischaemia and infarction
2
Q
presentation of an MI
A
- central, crushing chest pain that can radiate to the neck, arm or jaw
- not relieved by GTN, onset at rest or activity
- nausea, sweating and vomiting
- sense of impending doom
3
Q
diagnosis
A
- ECG
- troponin (I and T)
- creatinine kinase (CK)
4
Q
inferior STEMI ECG
A
II, III and aVF
5
Q
which coronary artery is an inferior STEMI
A
right coronary artery
6
Q
anterior STEMI ECG
A
V2-V5
7

10
Q
anterolateral STEMI ECG
A
I, aVL, V4-V6
11
Q

management of MI
A
- PCI
2. if PCI unavailable then thrombolysis (reteplase, alteplase or tenecteplase)
