    Health Behaviors and Patients with Coronary Artery Disease (CAD) : Role of Self-efficacy
    (Graphicsite, 2023-09-26) Chayanis Chobarunsitti; Sattha Prakobchai
    Cardiac disease is a major risk of mortality and morbidity globally. Patient with Coronary artery diseases are more likely than other chronic disease in poor health behavior either pre-treatment or post-treatment. Even though cardiac patients tried to seek the ways to promote their health, they might face with the difficulties to change the behavior. Numerous studies showed that self-efficacy plays a crucial role as a buffer to perform activity as reflect personal beliefs and confidence. We synthesize the evidences on self-efficacy and health behavior regarding smoking behavior, alcohol consumption, eating behavior, physical activity or exercise behavior and stress management.We found that most of the researchers successfully applied self-efficacy to promote physical activity or exercise among patients with coronary artery disease in short term period.Nurses should assess functional status and provide health education to promote well-being and encourage patients to perform and maintain their capability on health-promoting behaviors.

    Physical Activity and Heart Rate Variability Among Middle Age to Older Adults with Heart Failure: The State of Science
    (Graphicsite, 2024-04-30) Sattha Prakobchai; Kijja Suwan; Manida Dechakul
    Physical activity or exercise relates to the physiological responses especially in heart rate variability (HRV). HRV is a predictor of prognosis of heart failure and cardiac functions. However, little is known about the relationship of physical activity, HRV improvement and autonomic regulation in heart failure of older adults.The purpose of this state of science review is to synthesize the evidence that shows the effects of physical activity or exercise, HRV and physiological outcomes. The literature searched includes 12 studies from four electronic databases (PsycInfo, Pubmed, Scopus and CINAHL). The findings revealed that physical activity or exercise will improve HRV. This review showed that physical activity improves cardiac autonomic function (nerohormornal activation, sympathetovocal balance, baroreceptor reflex) and inhibits alpha 2 antagonist to improve HR reserve and RR intervals and prevent premature ventricular contraction (PVC). However, the level of physical activity and intensity are not clear. Tailored interventions or community-based programs will be effective in order to maintain physical activity and functional outcomes. A higher HRV is related to the functional capacity compared to the lower. Therefore, healthcare providers should regularly assess heart rate variability among heart failure patients to determine the threshold and recovery for physical functioning in regards to the stress form physical activity.
