- The Hemodynamic Basis of Atherosclerosis
-
- Atherosclerosis, the buildup of plaque deposits on the interior of blood
- vessels, is found in varying degrees of severity in all individuals and cannot
- be cured in the sense of eliminating an infectious disease. It is the price we
- pay for blood flow as a requirement of life. Atherosclerosis develops
- primarily from the fluid effects of blood flow, or hemodynamics, through
- various blood vessel sections as curvatures, branches, bifurcations, tapers,
- and external attachments. As blood flows through narrow or curved sections, an
- area of low pressure develops against the vessel wall, stimulating the normal
- layer of endothelium to proliferate. This plaque gradually enlarges and
- further reduces the flow area. For example, the plaque builds up on the convex
- surface of a curvature, where the flow-induced area of low pressure occurs.
-
- Data from human autopsy specimens, hydraulic system models, and atherosclerosis
- lesion production experiments support the conclusion that atherosclerosis is a
- reactive biological response of blood vessels to hemodynamics. Current
- research aims to minimize or retard the rate of development by controlling the
- relevant blood flow parameters. A promising area of research is the decrease
- in blood velocity, which is expected to retard the progressive development of
- atherosclerosis if achieved without impairing the metabolic requirements of
- vital organs.

- Meyer Texon received his A.B. (cum laude) from Harvard College and his M.D.
- from New York University School of Medicine. He has served as Assistant
- Medical Examiner for New York City. He is a practicing cardiologist and an
- Associate Professor of Forensic Medicine at the New York University Medical
- Center. Mr. Texon was awarded the Hektoen medal by the American Medical
- Association for his original research on Atherosclerosis.
