The Value of Autopsy Studies of Atherosclerosis in Human Subjects as We Approach the 21 st Century Study of Soldiers Killed in the Korean War Middle of Early Studies of Natural History in New Orleans 20 th Century International Atherosclerosis Project1960’s Community Pathology of Atherosclerosis in New Orleans1970’s Studies of Atherosclerosis and Risk Factors in Hisayama1970’s-1980’s The Akita Pathology Study Comparison of Atherosclerosis in Tokyo, New Orleans and Oslo Nationwide Study of Atherosclerosis in Infants and Children and Young Adults in Japan1980’s Bogalusa Hearty Study- Atherosclerosis in Children and Youth Histological Classification of Coronary Atherosclerosis in Young Subjects1980’s-1990’s Pathobiological Determinants of Atherosclerosis in Youth1980’s 1990’s
Coronary and Aortic Atherosclerosis in Young Men from Tokyo and New Orleans Toshiharu Ishii, William P. Newman III, Miguel A. Guzman, Yahuhiro Hosoda, Jack P. Strong Laboratory Investigation 1986; 54:561-565
Coronary Atherosclerosis in New Orleans and Japan, Men 25-44 Years of Age Percent Intimal Surface Involvement with Atherosclerotic Lesions
PDAY Pathobiological Determinants of Atherosclerosis in Youth Nationwide study of atherosclerosis in autopsied persons, 15-34 years old, conducted by 14 cooperating centers.
PDAY Study Subjects Males and females aged 15-34 Death due to external causes (accidents, homicides, suicides) 2876 cases collected
Institutions Participating in the Multicenter Cooperative Study, Pathobiological Determinants of Atherosclerosis in Youth University of Alabama Birmingham Albany Medical College Albany Baylor College of Medicine Houston University of Chicago Chicago The University of Illinois Chicago Louisiana State University Medical Center New Orleans University of Maryland Baltimore Medical College of Georgia Augusta University of Nebraska Medical Center Omaha The Ohio State University Columbus Southwest Foundation for Biomedical Research San Antonio The University of Texas Health Science Center San Antonio Vanderbilt University Nashville West Virginia State University Morgantown
PDAY Methods of Evaluating Atherosclerosis Visual estimate of surface involved by fatty streaks and raised lesions in Sudan-IV-stained arteries by three pathologists (LSU) Computerized image analysis of lesions in photographs of arteries (OSU) Computerized image analysis of histologic sections (OSU)
Risk Factors Measured in Autopsied Persons Risk FactorMarker Serum lipoprotein cholesterol and apolipoprotein concentrations Smoking Blood pressure Diabetes mellitus Obesity DNA Polymorphisms Total cholesterol, HDL cholesterol, and apolipoproteins in post mortem serum Thiocyanate in post mortem serum Wall thickness of renal arteries Glycosylated hemoglobin in post mortem red blood cells Body mass index and panniculus adiposus RFLP’s in liver DNA

Atherosclerosis begins in childhood with the appearance of aortic fatty streaks. Coronary fatty steaks begin to form in adolescence Most persons have coronary fatty streaks by the age 20-29 years.
In the PDAY study, the association of serum lipoprotein levels with atherosclerotic lesions in young persons 15-34 years of age supports the view that control the hyperlipoproteinemia will retard the progression of atherosclerosis in the young.
There is strong evidence for the effects of smoking on atherosclerosis in this young age group. The association of a hypertensive index to clinically significant raised arterial lesions is also well established in this young age group, 15-34 years of age. Elevated glycohemoglobin levels and obesity are associated with accelerated atherosclerosis in the third and fourth decades of life.
Control Programs to prevent coronary heart disease should be directed toward individuals in the twenties and thirties for maximum benefits Early detection and control of hypercholesterolemia hypertension, hyperglycemia and obesity in young persons should reduce the risk of atherosclerotic disease later in life. Dietary and other habits that retard atherosclerosis should be established in childhood.
