Several randomised controlled trials suggest that mindfulness-based approaches are helpful in preventing depressive relapse and recurrence, and the UK Government’s National Institute for Health and Clinical Excellence has recommended these interventions for use in the National Health Service. There are good grounds to suggest that mindfulness-based approaches are also helpful with anxiety disorders and a range of chronic physical health problems, and there is much clinical and research interest in applying mindfulness approaches to other populations and problems such as people with personality disorders, substance abuse, and eating disorders. We review the UK context for developments in mindfulness-based approaches and set out criteria for mindfulness teacher competence and training steps, as well as some of the challenges and future directions that can be anticipated in ensuring that evidence-based mindfulness approaches are available in health care and other settings.
BACKGROUND: Many anecdotes and several uncontrolled case series have suggested that emotionally stressful events, and more specifically, anger, immediately precede and appear to trigger the onset of acute myocardial infarction. However, controlled studies to determine the relative risk of myocardial infarction after episodes of anger have not been reported. METHODS AND RESULTS: We interviewed 1623 patients (501 women) an average of 4 days after myocardial infarction. The interview identified the time, place, and quality of myocardial infarction pain and other symptoms, the estimated usual frequency of anger during the previous year, and the intensity and timing of anger and other potentially triggering factors during the 26 hours before the onset of myocardial infarction. Anger was assessed by the onset anger scale, a single-item, seven-level, self-report scale, and the state anger subscale of the State-Trait Personality Inventory. Occurrence of anger in the 2 hours preceding the onset of myocardial infarction was compared with its expected frequency using two types of self-matched control data based on the case-crossover study design. The onset anger scale identified 39 patients with episodes of anger in the 2 hours before the onset of myocardial infarction. The relative risk of myocardial infarction in the 2 hours after an episode of anger was 2.3 (95% confidence interval, 1.7 to 3.2). The state anger subscale corroborated these findings with a relative risk of 1.9 (95% confidence interval, 1.3 to 2.7). Regular users of aspirin had a significantly lower relative risk (1.4; 95% confidence interval, 0.8 to 2.6) than nonusers (2.9; 95% confidence interval, 2.0 to 4.1) (P<.05). CONCLUSIONS: Episodes of anger are capable of triggering the onset of acute myocardial infarction, but aspirin may reduce this risk. A better understanding of the manner in which external events trigger the onset of acute cardiovascular events may lead to innovative preventive strategies aimed at severing the link between these external stressors and their pathological consequences.
BACKGROUND: Patterns of temporal variation of cardiac arrests may be important for understanding mechanisms leading to the onset of acute cardiovascular disorders. Previous studies have reported diurnal variation of the onset of cardiac arrests, with high incidence in the morning and in the evening, lack of daily variation during the week, and some seasonal variation. METHODS AND RESULTS: We explored weekly and yearly (seasonal) temporal variation in 6603 out-of-hospital cardiac arrests attended by the Seattle Fire Department. We observed daily variation that peaks on Monday and seasonal variation that peaks in the winter. CONCLUSIONS: Cardiac arrests do not occur randomly during the week or year but follow certain periodic patterns. These patterns are probably associated with patterns of activities.
BACKGROUND Seasonal and circadian variations in the occurrence of myocardial infarction and sudden cardiac death have been documented, suggesting that triggering factors may play a role in the causation of cardiac events. However, there are only sparse and conflicting data on the weekly distribution of the disorders. METHODS AND RESULTS To determine the weekly variation of acute myocardial infarction and sudden cardiac death, 5596 consecutive patients (71% men; age, 63 +/- 1 years) were analyzed in a regionally defined population (n = 330,000; age, 25 to 74 years) monitored from 1985 to 1990. The exact time of onset of symptoms was used to determine the day of the event. Patients with myocardial infarction (n = 2636) demonstrated a significant weekly variation (P < .01) with a peak on Monday, whereas patients with sudden cardiac death (n = 2960) were evenly distributed throughout the week. A similar weekly pattern was observed in subgroups of patients with myocardial infarction defined with respect to age, sex, cardiac risk factors, prior cardiac medication, and infarct characteristics. The working population demonstrated a weekly variation of myocardial infarction as opposed to the nonworking population, with a 33% increase in relative risk of disease onset on Monday (P < .05) and a trough on Sunday compared with the expected number of cases, if homogeneity was assumed. CONCLUSIONS The onset of acute myocardial infarction demonstrates a peak on Monday primarily in the working population. If this finding is confirmed in other communities, it may aid in identifying acute triggering events of myocardial infarction and perhaps in improving prevention of the disease.
