Type D personality negatively associated with self-care in Chinese heart failure patients

Journal of Geriatric Cardiology 2016年第5期13卷 401-407页

Background Little is known about the association between type D personality and self-care behaviors in heart failure （HF） patients. We examined the effect of type D personality on self-care behaviors and self-efficacy among Chinese HF patients. Methods A cross-sectional study with a convenience sample was conducted. All participants completed the questionnaires of the self-care of HF index （V6） and type D personality scale. Demographic and clinical variables were obtained from medical records and patient interviews. The me- thods used for data analysis included descriptive analysis, independent-sample t-test, Z2 test, and multiple linear regression. Results A total of 127 HF patients were included and 61.4% of them were male. The average age for this study sample was 64.9± 12.34 years. The majority of the participants were in a New York Heart Association class III or IV （87%）, and the average length of living with HF was 38.24 ± 41.1 months. A total of 33.1% of the participants were identified as having type D personality. No significant differences were determined in the demographic and clinical variables between type D and non-type D patients, except for the mean age and the length of living with HF. Type D patients were younger and had a shorter time of living with HF than their non-type D counterparts. Multiple regression demonstrated significant associations between type D personality and self-care maintenance and self-efficacy after adjusting the demographic and clinical factors. However, type D personality was not significantly associated with self-care management behaviors. Conclusions Type D personality was negatively related to self-care maintenance and self-efficacy in Chinese HF patients. Future study is warranted to develop a tailored intervention to improve engagement in self-care behaviors in HF patients with type D personality.

Effects of a nurse-led heart failure clinic on hospital readmission and mortality in Hong Kong

Background Heart failure （HF） is a physically and socially debilitating disease that carries the burden of hospital re-admission and mortality. As an aging society, Hong Kong urgently needs to find ways to reduce the hospital readmission of HF patients. This study evaluates the effects of a nurse-led HF clinic on the hospital readmission and mortality rates among older HF patients in Hong Kong. Methods This study is a retrospective data analysis that compares HF patient in a nurse-led HF clinic in Hong Kong compared with HF patients who did not attend the clinic. The nurses of this clinic provide education on lifestyle modification and symptom monitoring, as well as titrate the medications and measure biochemical markers by following established protocols. This analysis used the socio-demographic and clinical data of HF patients who were aged 〉 65 years old and stayed in the clinic over a six-month period. Results The data of a total of 78 HF patients were included in this data analysis. The mean age of the patients was 77.38 ± 6.80 years. Approximately half of the HF patients were male （51.3%）, almost half were smokers （46.2%）, and the majority received 〈 six years of formal education. Most of the HF patients （87.2%） belonged to classes II and III of the New York Heart Association Functional Classification, with a mean ejection fraction of 47.15± 20.31 ml. The HF patients who attended the clinic （n = 38, 75.13 ± 5.89 years） were significantly younger than those who did not attend the clinic （n = 40, 79.53 ± 6.96 years）（P = 0.04）, and had lower recorded blood pressure. No other statistically significant difference existed between the socio-demographic and clinical characteristics of the two groups. The HF patients who did not attend the nurse-led HF clinic demonstrated a significantly higher risk of hospital readmission [odd ratio （OR）： 7.40; P 〈 0.01] than those who attended after adjusting for the effect of age and blood pressure. In addition, HF patients who att

Evolvement of left ventricular assist device： the implications on heart failure management

Journal of Geriatric Cardiology 2016年第5期13卷 425-430页

作者： Sek Ying Chair Doris SF Yu Michael Timothy Ng Qun Wang Ho Yu Cheng eliza ml wong Janet WH Sit The Nethersole School of Nursing Faculty of Medicine The Chinese University of Hong Kong Hong Kong China Department of Psychology Faeulty of Social Science The Chinese University of Hong Kong Hong Kong China

Heart failure （HF） is a potentially fatal disease that affects increasing number of people worldwide. Although heart transplant is the ＂gold standard＂ therapy for HF, due to the limited availability of organs, many patients died when waiting for the transplant. Left ventricular assist device （LVAD）, as a mechanical circulatory support, has become a new light for patients with HF. With the technical advancements, LVADs work not only as a bridge to transplant, but also assist heart recovery and even as a destination therapy in long-term treatment. This observation paper reviewed the development of LVAD and its clinical roles. The challenges and possible solutions in nursing care for pa- tients with LVAD at different stage of implantation were discussed. The healthcare professionals could obtain a better understanding about the LVAD treatment for HF patients.
