THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations nor did they see the final draft of the report before its release. The review of this report was overseen by Floyd E. Bloom, M.D., The Scripps Research Institute, and Rogene F. Henderson, Ph.D., Lovelace Respiratory Research Institute. Appointed by the NRC, they were responsible for making certain that an independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution.
The untimely death of a family member, friend, or coworker from acute cardiovascular events is a tragedy that repeats itself too many times each day. Overall age-adjusted mortality rates for heart disease have fallen significantly since the 1950s. Yet heart disease is still the leading cause of death in the United States. Ischemic heart disease killed nearly 424,900 people in the United States in 2006; or about half of the heart attacks that occurred that year.
Largely we have been focused on prevention of ischemic heart disease at the individual level, through identification of genetic risk factors and modification of lifestyle factors such as diet and physical fitness. Chief among these has been smoking and the role that it has played both in chronic and acute cardiac diseases.
More recently we have begun to appreciate that the environment plays a role. Years of careful research have elucidated a role for fine particulate air pollution formed from the combustion of fossil fuels in premature mortality due to cardiac disease. As smoking bans were put in place a number of researchers observed that there were reductions in hospital admissions and deaths due to acute cardiovascular events.
In carrying out our research it became clear that, while we have learned much about why and how tobacco smoke and particulate air pollution aggravate cardiovascular disease, there is still much to learn. The paucity of information about cardiovascular toxicity of chemicals, even those in tobacco smoke, is indicative of the lack of attention that has been paid to environmental contributions to cardiovascular disease.
It is hoped that our report will spur efforts to learn more. Too many people die prematurely each year to do otherwise.
I am deeply appreciative of the expert work of our committee members: Neal Benowitz, Aruni Bhatnagar, Francesca Dominici, Steve Fienberg, Gary Friedman, Kathie Hammond, Jiang He, Suzanne Oparil, Eric Peterson, and Ed Trapido. This was an extraordinary group who each provided important contributions to the final report. It has been a privilege and a pleasure to work with the Institute of Medicine staff, study director Michelle Catlin and her excellent team Rita Deng and Raina Sharma, as well as Jennifer Saunders and Naoko Ishibe, Sc.D. Without them, this report would not have been possible. I thank those who provided expert presentations and background materials and gave us much to think about: Captain Matthew McKenna, M.D., M.P.H. and Darwin Labarthe, M.D., M.P.H., Ph.D., Centers for Disease Control and Prevention; Stanton Glantz, Ph.D., University of California, San Francisco; Joel Kaufman, M.D., M.P.H., University of Washington, Seattle; Jon Samet, M.D., University of Southern California; Cynthia Hallett, American Nonsmokers’ Rights Foundation; and Jared Jobe, Ph.D., National Heart, Lung and Blood Institute of the National Institutes of Health. In addition, I would like to thank individuals who assisted with the additional analyses of the committee: Aidan McDermott and Howard Chang, both from the Department of Biostatistics, Bloomberg School of Public Health, Johns Hopkins University. And, last, but certainly not least, I am appreciative of the time and effort offered by our reviewers, Floyd E. Bloom (monitor), Rogene F. Henderson (coordinator), Scott Appleton, John C. Bailar III, Robert Brook, Stanton A. Glantz, Christopher B. Granger, C. Arden Pope, Peter Rosen, Jonathan M. Samet, Michael Siegel, Ponisseril Somasundaran, and Noel S. Weiss.
