BACKGROUND Some cases of acute coronary syndrome (ACS) may be triggered by emotional states such as anger, but it is not known if acute depressed mood can act as a trigger. METHODS 295 men and women with a verified ACS were studied. Depressed mood in the two hours before ACS symptom onset was compared with the same period 24 hours earlier (pair-matched(More)
AIMS Resumption of paid employment following acute coronary syndrome (ACS) is an important indicator of recovery, but has not been studied extensively in the modern era of acute patient care. METHODS AND RESULTS A total of 126 patients who had worked before hospitalization for ACS were studied with measures of previous clinical history, ACS type and(More)
OBJECTIVE Type-D or "distressed" personality and depression following admission for acute coronary syndrome (ACS) have been associated with poor clinical outcome. The biological pathways underpinning this relationship may include disruption of the hypothalamic-pituitary-adrenocortical (HPA) axis. We therefore assessed cortisol output in patients who had(More)
BACKGROUND Pre-hospital delays in patients experiencing acute coronary syndromes (ACS) remain unacceptably long. AIMS To examine simultaneously a wide range of clinical, sociodemographic and situational factors associated with total pre-hospital delay and its two components. METHODS Pre-hospital delay data were collected from 228 patients with ACS using(More)
OBJECTIVES To assess the prevalence and predictors of posttraumatic stress symptoms in patients at 12 and 36 months post hospital admission for an acute coronary syndrome (ACS). There is increasing recognition that posttraumatic stress may develop in the aftermath of an acute cardiac event. However, there has been little research on the longer-term(More)
Experiencing an acute coronary syndrome (ACS) may provoke a range of negative emotional responses, including acute distress and fear of dying. The frequency of these emotional states has rarely been assessed. This study examined the presence and severity of the fear of dying and acute distress in 184 patients with ACS and analyzed its correlates and(More)
Fruit and vegetable consumption is below recommended levels in the population, paricularly in low-income groups. This study assessed factors associated with self-reported intake and 2 biomarkers (potassium excretion and plasma vitamin C) in 271 adults living in a low-income neighborhood. Attitudinal barriers to change were negatively related to reported(More)
BACKGROUND The determinants of depression following acute coronary syndrome (ACS) are poorly understood. Triggering of ACS by emotional stress and low socio-economic status (SES) are predictors of adverse outcomes. We therefore investigated whether emotional triggering and low SES predict depression and anxiety following ACS. METHOD This prospective(More)
OBJECTIVE To assess the relationship among Type D personality, self-efficacy, and medication adherence in patients with coronary heart disease. METHODS The study design was prospective and observational. Type D personality, self-efficacy for illness management behaviors, and medication adherence were measured 3 weeks after hospitalization for acute(More)
OBJECTIVE To measure the effect of brief behavioural counselling in general practice on patients' consumption of fruit and vegetables in adults from a low income population. DESIGN Parallel group randomised controlled trial. SETTING Primary health centre in a deprived, ethnically mixed inner city area. PARTICIPANTS 271 patients aged 18-70 years(More)
