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.

Self-rated competency and education/programming needs for care of the older adult with cardiovascular disease : A survey of the members of the council of cardiovascular nursing
AbstractHolm, K., Chyun, D., & Lanuza, D. M. (2006). In Journal of Cardiovascular Nursing (Vols. 21, Issues 5, pp. 363-366). 10.1097/00005082-200609000-00006AbstractAn online survey, Care of the Older Adult with Cardiovascular Disease (COA-CVD), was used to describe self-rated competency in the care of the aging adult with cardiovascular disease and subsequently determine the future education and programming needs of the Council of Cardiovascular Nursing. Respondents indicated that developing relationships, patient teaching, and assessment were areas where they felt most competent. The areas of highest priority for future programming included assessment of the older adult, diagnosis of health status, deriving a plan of care, implementing a treatment plan, patient teaching, and ensuring quality care. Most stated that content relative to the care of the older adult should be available at the annual meeting, Scientific Sessions of the American Heart Association, followed by self-study modules (65%), local and regional conferences (64%), and stand-alone national conferences (53%). The conclusions are that the Council of Cardiovascular Nursing and its membership need to address the importance of care of aging adults with cardiovascular disease and stroke in future programming. Although the Scientific Sessions of the American Heart Association is an appropriate venue, efforts can be directed toward developing self-study modules and local and regional conferences. As always, there is a need to work collaboratively with the other councils of the American Heart Association and other nursing organizations who view the care of the older adult as a high priority.Social support, self-efficacy, and adherence to self-care requirements in patients with coronary artery disease

In Journal of Nuclear Cardiology (Vols. 13, Issues 3, pp. 362-368). 10.1016/j.nuclcard.2006.01.022AbstractBackground: Endothelial dysfunction precedes overt atherosclerosis and is present in patients with type 2 diabetes mellitus (T2DM). Myocardial perfusion imaging (MPI) is an effective method of detection of coronary artery disease (CAD); however, the relationship between endothelial function and MPI in asymptomatic patients with T2DM has not been examined. Methods and Results: This study used a subset of the population from the Detection of Ischemia in Asymptomatic Diabetics (DIAD) study. Endothelium-dependent vasodilation (EDV) and endothelium-independent vasodilation (EIV) were measured by use of brachial artery ultrasonography in 75 asymptomatic patients with T2DM (56 men; mean age, 58.6 ± 6.4 years; mean duration of diabetes, 8.4 ± 7.5 years) who underwent adenosine MPI. Of the patients, 15 (20%) had evidence of relative ischemia (MPI+) whereas 60 (80%) had a normal study (MPI-). Both EDV (3.5% ± 3.7% vs 4.5% ± 6.6%, P = not significant) and EIV (15.1% ± 7.5% vs 16.8% ± 8.4%, P = not significant) were similar in the 2 groups. On the basis of a receiver-operator analysis, an EDV response of 8% was selected as a cut point, with a negative predictive value of 93% (13/14 subjects with EDV ≥8% were MPI-). Conclusions: Endothelial function in asymptomatic patients with T2DM is not associated with the presence of relative myocardial ischemia by MPI; however, an EDV of 8% or greater has a high negative predictive value for the exclusion of CAD.Angina

AbstractWagner, J., Lacey, K., Chyun, D., & Abbott, G. (2005). In Patient Education and Counseling (Vols. 58, Issue 1, pp. 82-87). 10.1016/j.pec.2004.07.004AbstractThis paper describes a paper and pencil questionnaire that measures heart disease risk knowledge in people with diabetes. The Heart Disease Fact Questionnaire (HDFQ) is a 25-item questionnaire that was developed to tap into respondents' knowledge of major risk factors for the development of CHD. Approximately half of these items specifically address diabetes-related CHD risk factors. Based on extensive pilot data, the current study analyzed responses from 524 people with diabetes to assess the psychometric properties. The HDFQ is readable to an average 13-year old and imposes little burden. It shows good content and face validity. It demonstrates adequate internal consistency, with Kuder-Richardson-20 formula = 0.77 and good item-total correlations. Item analysis showed a desirable range in P-values. In discriminant function analyses, HDFQ scores differentiated respondents by knowledge of their own cardiovascular health, use of lipid lowering medications, health insurance status, and educational attainment, thus indicating good criterion related validity. This measure of heart disease risk knowledge is brief, understandable to respondents, and easy to administer and score. Its potential for use in research and practice is discussed. Future research should establish norms as well as investigate its test-retest reliability and predictive validity.
