Independent predictors of physical health in community-dwelling patients with coronary heart disease in Singapore

Postoperative Cognitive Behavioral Intervention in Patients with Coronary Heart Disease Based on the Effect of Nursing Process Reengineering

With the development of society and economy, patients with coronary heart disease increasingly hope to receive more humanized services after surgery, and the reengineering of the nursing process is precisely based on humanized management. In order to create a nursing intervention that helps in boosting total nursing gains and lowering disasters, the primary element of the nursing business process reengineering is to reintegrate or condense the creative work flow that was fragmented by specialization into a whole job. The “patient” is positioned in the center of nursing process reengineering, with service quality as the main guiding principle. It follows the management principles of continuous regulation and innovation, and cultivates and promotes the development of the nursing field from the perspective of “sublation.” In the method part, this article introduces and supplements related information on nursing process reengineering, coronary heart disease, and postoperative cognitive behavioral intervention. Algorithmically, this paper proposes 3D RPN structure, loss function, capsule network, and improved activation function algorithm for coronary heart disease region extraction. In the part of experiment and results, this article collects general data of patients and compares memory ability, grades of self-management behaviors of patients treated with coronary heart disease, scores of quality control standards before and after nursing process reengineering, scores of patients' mental state, and comparison of postoperative physical indicators. According to the test results, the test group's diastolic and systolic blood pressure declined by more than 20, their total cholesterol dropped from 6.23 to 5.28, and their triglyceride levels dropped from 1.82 to 1.39 after the stent was implanted. Triglycerides reduced from 1.82 to 1.39, and total cholesterol dropped from 6.15 to 5.98. It indicates postoperative memory in patients with coronary heart disease. Abilities, including recognition, number, touch memory, and associative memory, decline significantly, but it can be improved after receiving the nursing process reengineering. It can be seen that nursing process reengineering can play a positive role in the postoperative cognitive behavior of patients with coronary heart disease.

Application of Ferrans et al.'s conceptual model of health-related quality of life: A systematic review

Ferrans, Zerwic, Wilbur, and Larson proposed the conceptual model of health-related quality of life (HRQOL) in 2005 to explicate the constructs associated with HRQOL and to describe the associations among those constructs. In this systematic review, the authors aimed to describe empirical studies that used Ferrans et al.'s model and to examine the evidence related to the hypothesized model concepts. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Relevant articles were identified using Crossref, CINAHL, and PubMed. To be included, studies had to employ the model as a theoretical framework and be published in English between 2005 and 2020. Type of theory use was coded using four designations: informed by theory, applied theory, testing theory, and building theory. Thirty-one studies were included. Most studies involved adult patients with chronic illnesses (n = 20) and were conducted in Western countries (n = 22). The most common type of theory use was testing theory (74.19%). Among the seven concepts in Ferrans et al.'s model, all 20 hypothesized associations were tested and 19 were supported by study results. The three associations most frequently supported were between symptoms and functional status (n = 13), environmental characteristics and quality of life (n = 10), and individual characteristics and functional status (n = 8). No studies found an association between environmental characteristics and biological function. Our review found that Ferrans et al.'s model has been used extensively to guide HRQOL research. An emerging body of research provides preliminary support for the associations hypothesized in the model. Additional research is needed to confirm the hypothesized associations among model concepts.

Physical Activity and Cardiac Self-Efficacy Levels During Early Recovery After Acute Myocardial Infarction: A Jordanian Study

BACKGROUND

Regular physical activity is important for patients with established coronary heart disease as it favorably influences their coronary risk profile. General self-efficacy is a powerful predictor of health behavior change that involves increases in physical activity levels. Few studies have simultaneously measured physical activity and self-efficacy during early recovery after a first acute myocardial infarction (AMI).

PURPOSE

The aims of this study were to assess changes in objectively measured physical activity levels at 2 weeks (T2) and 6 weeks (T3) and self-reported cardiac self-efficacy at hospital discharge (T1) and at T2 and T3 in patients recovering from AMI.

METHODS

A repeated-measures design was used to recruit a purposive sample of patients from a single center in Jordan who were diagnosed with first AMI and who did not have access to cardiac rehabilitation. A body-worn activity monitor (activPAL) was used to objectively measure free-living physical activity levels for 7 consecutive days at two time points (T2 and T3). An Arabic version of the cardiac self-efficacy scale was administered at T1, T2, and T3. Paired t tests and analysis of variance were used to examine differences in physical activity levels and cardiac self-efficacy scores, respectively.

RESULTS

A sample of 100 participants was recruited, of which 62% were male. The mean age of the sample was 54.5 ± 9.9 years. No statistically significant difference in physical activity levels was measured at 2 weeks (T2) and 6 weeks (T3). Cardiac self-efficacy scores improved significantly between T1, T2, and T3 across subscales and global cardiac self-efficacy.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Participants recovering from AMI in Jordan did not increase their physical activity levels during the early recovery phase, although cardiac self-efficacy scores improved. This may be because the increase in cardiac self-efficacy was not matched by the practical skills and knowledge required to translate this positive psychological construct into behavioral change. This study provides a first step toward understanding the complex relationship between cardiac self-efficacy and physical activity in this population. The authors hope that these findings support the design of culturally appropriate interventions to increase physical activity levels in this population.

Analysis and Evaluation of Conceptual Model for Health-Related Quality of Life Employing Fawcett and DeSanto-Madeya's Critique Framework

Health-related quality of life is increasingly used as a predictor in nursing research and practice because its multidimensional constructs encompass the holistic spectrum of care. This article comprehensively analyzes and evaluates the conceptual model of health-related quality of life of Ferrans and colleagues using Fawcett and Desanto-Madeya's 2013 framework. The model encompasses all relevant concepts and propositions in its theoretical foundation while maintaining consistency with the nursing metaparadigm. Also, the model has comprehensive content, appropriate context, and social and theoretical significance. To maximize the model's empirical and pragmatic adequacy, researchers should carefully define the variables associated with each concept.

Depression Levels Following Discharge Predict Quality of Life in Heart Disease Patients

Abstract Depression and stress have been related with poor Health Related Quality of Life (HRQoL) prognosis. However, it is not clear when these depressive symptoms should be measured. A sample of 177 Coronary Heart Disease patients were followed for 15 months aimed to compare the effect of depression and stress measure at time of hospitalization and three months later on the physical HRQoL trajectory. Linear growth models’ results showed that depression and stress after discharge are negatively correlated with the physical HRQoL and depressive symptoms negatively affect the prognosis of these patients.

The effect of a self-help psychoeducation programme for people with coronary heart disease: A randomized controlled trial

AIM

To examine the effect of a self-help psychoeducation program for people with coronary heart disease in Singapore.

BACKGROUND

Cardiac rehabilitation has shown benefits for mitigating many cardiac risk factors and can lead to improvement in health-related quality of life and psychological well-being in people with heart disease. However, traditional hospital-based cardiac rehabilitation faces substantial challenges. A self-management cardiac rehabilitation program offers an avenue to increase uptake and empowers patients to manage their condition at home.

DESIGN

A two-arm, randomized controlled trial.

METHODS

A total of 129 patients with coronary heart disease were recruited from an outpatient clinic in a public hospital in Singapore from April 2015-January 2016. They were randomly assigned to the intervention group or the control group. Participants in the intervention group received the 4-week home-based self-help psychoeducation program. Outcomes were measured at baseline and at 4 weeks and 16 weeks from the baseline.

RESULTS

There were no significant differences in health-related quality of life, psychological status (i.e., perceived stress level, anxiety, and depression levels), or cardiac physiological risk parameters between the intervention and the control groups immediately after the program or at different time points. There was also no significant difference in unplanned health service use at the 16 week posttest point between the two groups.

CONCLUSIONS

This study did not find any significant effect of our program on outpatients with coronary heart disease. Nonetheless, findings on participant characteristics may offer healthcare professionals valuable insights to help facilitate future development of an effective cardiac rehabilitation program catered to outpatients with coronary heart disease.

TRIAL REGISTRATION

The study has been registered with ISRCTN registry. The trial registration number is ISRCTN15839687.

Chinese translation and psychometric testing of the cardiac self-efficacy scale in patients with coronary heart disease in mainland China

Background

A person’s self-efficacy plays a critical role during the chronic management process of a health condition. Assessment of self-efficacy for patients with heart diseases is essential for healthcare professionals to provide tailored interventions to help patient to manage the disease.

Objective

To translate and test the psychometric properties of the Chinese version of Cardiac Self-efficacy Scale (C-CSES) as a disease-specific instrument for patients with coronary heart disease (CHD) in mainland China.

Methods

The original English version of the CSES was translated into Chinese using a forward-backward translation approach. A convenience sample consisting of 224 Chinese patients with CHD were recruited from a university-affiliated hospital in Shiyan, China. The C-CSES and the General Self-efficacy Scale (GSES) were used in this study. The factor structure, convergent and discriminative validities, and internal consistency of the C-CSES were evaluated.

Results

The confirmatory factor analysis (CFA) supported a three-factor high-order structure of the C-CSES with model fit indexes (RMSEA = 0.084, CFI = 0.954, NNFI = 0.927, IFI = 0.954 and χ ² /df = 2.572). The C-CSES has good internal consistency with a Cronbach’s alpha of 0.926. The convergent validity of the C-CSES was established with significantly moderate correlations between the C-CSES and the Chinese version of the GSES (p < 0.001). The C-CSES has also shown good discriminative validity with significant differences of cardiac self-efficacy being found between patients with and without comorbidities of hypertension, diabetes, or heart failure.

Conclusion

The empirical data supported that the C-CSES is a valid and reliable disease-specific instrument for assessing the self-efficacy of Chinese patients with CHD.

Relação entre estresse percebido com coping e estressores de pacientes em pré-operatório de revascularização miocárdica

La enfermedad coronaria se destaca entre las enfermedades cardiovasculares al victimizar pacientes en todo el mundo. En el periodo preoperatorio de cirugía de revascularización miocárdica (CRM), ocurre estrés. Objetivo: averiguar la relación entre estrés percibido con coping y con estresores de pacientes en preoperatorio de CRM. Materiales y método: enfoque cuantitativo y transversal. La muestra se compuso de 105 pacientes coronariopatas internados en hospital cardiológico. Se utilizaron Escala de Estrés Percibido, Inventario de Estrategias de Coping y dos preguntas abiertas cuyas respuestas fueron cuantificadas y categorizadas. Para el análisis de datos, se utilizó regresión lineal multivariada. Resultados: mayor estrés percibido se relacionó con mayor Escape y esquiva (β = 0,416, p < 0,001), mayor Afrontamiento (β = 0,353, p = 0,001), menor Autocontrol (β = –0,226, p = 0,024), Sexo femenino (β = –0,173, p = 0,048) y “Síntomas clínicos” (β = 0,235, p = 0,015). “Búsqueda por ocupar la mente” (β = –0,196, p = 0,047) y “Afrontar la cirugía como instru- mento de mejoría/cura” (β = –0,255, p = 0,009) se relacionaron con menor estrés percibido. Conclusiones: el estrés percibido sufre variabilidad según determinados estresores y coping. Tales relaciones se deben tener en cuenta para la planeación de la asistencia en enfermería con el fin de reducir el estrés preoperatorio de pacientes coronariopatas.
