Timeline - post IM complications Flashcards
Papillary mm rupture
5-10 days post MI
Due to weakening of necrotic myocardium as macrophages degrade structural tissue and form weak granulation tissue
Arrhythmias
2 days post-MI
Chronic CHF
Months after MI
Dressler syndrome (autoimmune pericarditis)
Several weeks post MI
True ventricular aneurysms
several weeks post MI
What part of the heart is most likely affected in myocardial rupture after an MI?
LV (lower 1/3 of anterior wall)
Often occurs during 1st week when myocardial necrosis is at a max
LV free wall rupture
5-14 days post MI
Rupture –> hemopericardium and cardiac tamponade –> profound hypotension and shock –> death
Most freq complication of fibrinolytic therapy?
bleeding (GI, intracranial)
