MI complications

Question 1

MI complications

Answer 1

1) cardiac arrhythmias
2) cardiogenic shock
3) ventricular free wall rupture
4) ventricular aneurysm formation
5) postinfarction fibrinous pericarditis
6) Dressler’s syndrome

Question 2

Cardiac arrhythmias

Answer 2

Important cause of death before reaching hospital, common in first few days LV failure and pulm edema

Question 3

Cardiogenic shock

Answer 3

Large infarct, high risk of mortality

Question 4

Ventricular free wall rupture

Answer 4

Cardiac tamponade;
papillary muscle rupture;
severe mitral regurg;
IV septum rupture => VSD

Question 5

Ventricular aneurysm formation

Answer 5

Low CO
risk of arrhythmias
embolus from mural thrombus
greatest risk 1 week post MI

Question 6

Post infarction fibrinous endocarditis

Answer 6

Friction rub (1-3 days post MI)

Question 7

Dressler’s syndrome

Answer 7

Autoimmune phenomenon resulting from fibrinous pericarditis (several weeks post MI)
