Cardiovascular disease epidemic in the developing world

Narrator:       This is Science Today. In the United States, stroke has dropped from the third leading cause of death to fourth, while heart disease remains the No.1 killer. But in other countries, like China, stroke is the leading cause of death and heart disease is relatively lower.

Kim:               One of the questions that I had was whether or not the patterns of disease across the globe are related to national income or not.

Narrator:       Using data from the World Health Organization, researcher Anthony Kim of the University of California, San Francisco, found that heart disease and stroke worldwide do seem to be tied to national income.

Kim:               We think of infectious diseases as a major scourge in the developing world. But there is an ongoing epidemic of cardiovascular disease in developing world that's expected to worsen with time and needs to be addressed directly, so that appropriate resources can be marshaled to deal with this epidemic.

Narrator:       For Science Today, I'm Larissa Branin.
