Pulse pressure. Considerable evidence suggests that pulse pressure serves as an important risk factor for future cardiovascular events. This video clip explains the derivation of pulse pressure and some of the pathophysiology that determines this parameter. (With permission from the Academy for Health Care Education.)

Formation and complication of atherosclerotic plaques. We now understand the generation of atherosclerotic plaques as a dynamic process involving an interchange between cells of the artery wall, inflammatory cells recruited from blood, and risk factors such as lipoproteins. This video animation reviews current thinking about how risk factors alter the biology of the artery...

Metabolic syndrome. A number of important cardiovascular risk factors tend to cluster in a pattern described by some as the "metabolic syndrome." While controversy persists regarding whether cardiovascular risk due to these factors is additive or synergistic, their clinical importance is growing. This animation discusses some of the metabolic derangements that underlie the "metabolic syndrome."
