What is a complication of myocardial infarction that results from a thinning of the myocardial wall and increases risk of thrombus, ventricular arrhythmias, and heart failure?
a. papillary necrosis
b. left ventricular dysfunction
c. ventricular aneurysm
d. ventricular rupture
Answer: c. ventricular aneurysm
Ventricular aneurysm is a complication of myocardial infarction tha results from a thinning of the myocardial wall and increases risk of thrombus, ventricular arrhythmias, and heart fialure.
