Cardiovascular Epidemiology in a Changing World--Challenges to Investigators and the National Heart, Lung, and Blood Institute

Over the past 60 years, revolutionary discoveries made by epidemiologists have contributed to marked declines in cardiovascular disease morbidity and mortality. Now, in an era of increasingly constrained resources, researchers in cardiovascular epidemiology face a number of challenges that call for novel, paradigm-shifting approaches. In this paper, the authors pose to the community 4 critical questions: 1) How can we avoid wasting resources on studies that provide little incremental knowledge? 2) How can we assure that we direct our resources as economically as possible towards innovative science? 3) How can we be nimble, responding quickly to new opportunities? 4) How can we identify prospectively the most meritorious research questions? Senior program staff at the National Heart, Lung, and Blood Institute invite the epidemiology community to join them in an ongoing Web-based blog conversation so that together we might develop novel approaches that will facilitate the next generation of high-impact discoveries.
