Question 4

Patients with increased risk for myocardial infarction also have an increased risk of stroke. What is the relationship between these problems? Select all correct answers.

a. Atherosclerosis is the prominent underlying pathology for both stroke and MI.
b. If thrombus forms on parts of the heart wall damaged by an MI, it can break off and embolize the brain producing a stroke.
c. If damage to the heart wall leads to atrial fibrillation, this increases the risk that thrombus will be formed in the left atrium, and that a piece will leave the heart, and travel in the systemic circulation to the brain where it can block a vessel and produce a stroke.
d. Hypertension causes damage to the walls of both coronary and cerebral vessels.
e. Cigarette smoking causes changes in the blood such as increased sticking together of platelets and faster clotting times that would promote clot formation in both coronary and cerebral vessels.
