A 51-year-old man with a history of transmural MI one month ago presents with sudden occlusion of his abdominal aorta. The following is/are true:

a. Most likely location of the MI is anterolateral

b. The vast majority of emboli occur within 6 weeks of the occurrence of the MI

d. Heparin can reduce the incidence of embolism after MI 

Acute MI with endocardial thrombus is the second most common cause of arterial embolism most commonly within 6 weeks, and the most typical location postmortem is anterolateral. Arterial embolism after MI is associated with an increase in mortality rate. Heparin following acute MI has been shown to reduce the incidence of systemic arterial embolism.
