MI complications Flashcards
What are common causes of death post-MI?
VF
LVF
CVA
Examples of early complications?
Death Pericarditis Rupture Arrthyhmias Heart failure
Examples of late complications?
Aneurysm
Embolism
Dressler’s syndrome
How does pericarditis present?
Mild fever, central chest pain, relieved by sitting forward
Signs of pericarditis?
Pericardial friction rub
ECG: saddle shaped ST elevation +/- PR depression
Types of rupture that can occur post-MI?
Ventricular free wall rupture (cardiac tamponade, Beck’s triad)
Papillary muscle rupture (blowing PSM, pulmonary oedema)
Septal rupture (PSM, raised JVP, RHF)
What is Beck’s triad?
3 signs of cardiac tamponade:
Hypotension
Raised JVP
Muffled heart sounds
Examples of SVTs?
Sinus tachycardia
Atrial fibrillation
Atrial flutter
Examples of ventricular tachycardias?
PVCs
Sustained VT
VF (commonest cause of death post-MI)
Examples of bradycardias?
Sinus bradycardia
AV block (treat if Mobitz type II)
Ventricular bradycardia
When do ventricular aneurysms typically present?
4-6 weeks post-MI
What is the ECG sign for ventricular aneurysms?
SUSTAINED ST ELEVATION
If patients are at high risk of embolic disease post-MI, what drug should they be started on?
Warfarin for 3 months after large anterior MI
What is Dressler’s syndrome?
Autoimmune mediated pleuro-pericarditis (antibodies against myocyte sarcolemma)
How does Dressler’s syndrome present?
Recurrent pericarditis (fever, central chest pain, relieved by sitting forward)
Pleural effusions
Anemia
Raised ESR
