I have been the medical director for several nursing homes, and medical director for the Veterans Administration home care program. I have done laboratory work on the renin angiotensin aldosterone axis in human beings as they age. Plasma renin activity and aldosterone concentrations are known to be lower in the blood of older human beings. It is not clear if this leads to clinical problems in older adults. In the laboratory, we studied platelet receptors for angiotensin in relationship to age, blood pressure and plasma renin activity.
Platelet receptors increase in number in older adults.
This appears to reflect regulation in response to low renin angiotensin aldosterone axis activity. I am an attending physician on the University of Wisconsin Hospital Geriatrics Service, and Medical Director of UW Clinics East and the Oakwood Clinic. The Section of Geriatrics and Gerontology has a large emphasis on primary care, and we see patients at these sites. I have a keen interest in teaching and have been involved in teaching medicine, primary care and geriatric medicine. I am an instructor in Clinical Medicine and Practice, and a preceptor in the Generalist Partners Program at the Medical School.
