What is afterload?
Afterload is the pressure the heart must generate to move blood into the aorta.
What is cardiac contractility?
Cardiac contractility is the ability of the heart to change its force of contraction without changing its
resting (diastolic) length.
What is an inotrope?

What is mean arterial pressure?
An inotropic influence is one that increases the strength of the muscular contraction.
What is thrombocytosis?
Thrombocytosis is defined as an elevated platelet count above 450,000/µL.
What are the most common causes of inherited disorders of hypercoagulability?
Factor V gene and prothrombin gene
What are acquired or secondary factors of hypercoagulability that lead to venous stasis?
Prolonged bed rest and immobility, myocardial infarction, cancer, hyperestrogenic states, oral
contraceptives, smoking, and obesity
What is thrombocytopenia?
