Disorders of the Cardiovascular System
You are appointed as a cardiac epidemiologist advisor on an international committee setting global health policy. Your committee is assigned to predict health trends in a Pacific East Asian nation with a population and environment very similar to China. At this point in history, the nation is just moving from the first classic stage in the epidemiologic transition (“pestilence and famine”) to the second classic stage (“receding pandemics”). In regard to the anticipated patterns of cardiovascular disease (CVD) in this nation, which of the following is true?
Explanation
ExplanationThe global rise in cardiovascular disease (CVD) is the result of an unprecedented transformation in the causes of morbidity and mortality during the 20th century. Known as the epidemiologic transition, this shift is driven by industrialization, urbanization, and associated lifestyle changes and is taking place in every part of the world among all races, ethnic groups, and cultures. The transition is divided into four basic stages: pestilence and famine, receding pandemics, degenerative and man-made diseases, and delayed degenerative diseases. A fifth stage, characterized by an epidemic of inactivity and obesity, is emerging in some countries.
