Deborah A Chyun's additional information
-
-
Dr. Chyun's expertise on cardiac-related outcomes, psychosocial and behavioral factors, quality of life in older adults with type 2 diabetes mellitus, and cardiovascular nursing and chronic disease epidemiology has provided a unique opportunity to expand the understanding of cardiovascular disease (CVD) in older adults through multiple studies. Findings have made a significant contribution to knowledge of cardiac autonomic neuropathy and asymptomatic heart disease, and have been incorporated into American Diabetes Association clinical practice recommendations. She has lectured and consulted nationally and internationally on topics related to type 2 diabetes and CVD. As an active member of the American Heart Association, Dr. Chyun has represented nursing on interdisciplinary committees focusing on prevention, epidemiology, diabetes, and older adults.

AbstractChyun, D. A. (1985). Heart and Lung: Journal of Acute and Critical Care, 14(3), 223-227.AbstractAlthough fairly large individual discrepancies were noted between the systolic and diastolic readings obtained through intra-arterial and auscultatory methods, the mean differences in these readings were not found to be significant. In agreement with AHA standards, the disappearance of sound was found to be a better indicator of intra-arterial diastolic pressure than was muffling. The only hemodynamic variable that had a significant relationship (p < 0.001) with the discrepancy in diastolic readings was heart rate. The level of systolic and diastolic pressure readings, pulse pressure, and PVR varied minimally in this sample. Extremely high and low values were present when these parameters were correlated with discrepancies in other studies. While CO/CI and SV were depressed in most of the sample, in this limited number of subjects, these parameters alone, were not found to be associated with a discrepancy. The findings of this study suggest the following implications for clinical practice and further research: 1. Cuff size needs to be individualized for each patient. 2. Palpatory readings should be obtained before auscultation. 3. A way to determine the frequency response and damping coefficient should be available and used when comparing intra-arterial and auscultatory readings. 4. Simultaneous auscultatory and intra-arterial pressures should be taken in the same arm when assessing any discrepancy. In addition, auscultatory and palpatory, brachial and forearm pressures should be compared with an intra-arterial reading. Measurements of brachial and radial blood flow in the forearm would be useful in seeking to explain a discrepancy between measurement methods.Pregnancy and Cardiac Valvular Prostheses
AbstractCHYUN, D. A. (1985). Journal of Obstetric, Gynecologic, & Neonatal Nursing, 14(1), 38-44. 10.1111/j.1552-6909.1985.tb02201.xAbstractMany women who have had cardiac valve replacements have reached or will soon be reaching childbearing age. Pregnancy exposes these women to potential problems resulting from the previous valvuloplasty. The three most common problems in this population–thromboembolism, infective endocarditis, and myocardial decompensation are discussed through a review of current literature. Preventive measures and treatment modalities are presented in order to assist nurses caring for these clients during their pregnancy.Intravenous nitroglycerin in ischemic heart disease
