Abstract
BackgroundPatients with coronary heart disease (CHD) experienced poor physical health which was found to be associated with higher hospital readmission rates and increased mortality. The study aimed to identify the independent predictors of physical health in Singaporean patients with CHD.MethodsA consecutive sample of 129 patients with CHD was recruited from the medical heart clinic of a tertiary public hospital in Singapore. A set of questionnaires including the Short Form 12-item health survey version 2, Perceived Stress Scale, Hospital Anxiety and Depression Scale, and Cardiac Self-Efficacy Scale were used to measure the study outcomes. The patients’ socio-demographic and clinical data were also collected.ResultsA multivariate linear regression analysis indicated that depression (B = −0.766, p < 0.05) and self-efficacy for maintaining function (B = 2.351, p < 0.05) remained significant while the other variables were adjusted and identified as the independent predictors of physical health in Singaporean patients with CHD.ConclusionsThis study has shed some light on the key factors influencing the physical health of Singaporean patients with CHD. The finding suggests tailored interventions that target mitigating a patient’s depression and promote self-efficacy for maintaining function may be helpful in improving patients’ physical health and quality of life.
Highlights
Patients with coronary heart disease (CHD) experienced poor physical health which was found to be associated with higher hospital readmission rates and increased mortality
It has been well documented that patients with CHD experience poor health-related quality of life (HRQoL) [2, 3]
In terms of clinical characteristics, the length of diagnosis of CHD ranged from 1 month to 30 years, all participants (100 %) had a history of high cholesterol, 83.7 % had hypertension, and close to half (44.2 %) of them had Type 2 Diabetes. 57.4 % of the participants were ex-smokers
Summary
Patients with coronary heart disease (CHD) experienced poor physical health which was found to be associated with higher hospital readmission rates and increased mortality. The study aimed to identify the independent predictors of physical health in Singaporean patients with CHD. It has been well documented that patients with CHD experience poor health-related quality of life (HRQoL) [2, 3]. The physical health component of HRQoL was an important outcome measure for patients with CHD [5]. Poor physical health was found to be associated with higher hospital readmission rates and increased mortality [5]. Numerous studies have identified the determinates of physical health in patients with CHD, and many factors have
