Treatment of Anxiety in Patients With Coronary Heart Disease: A Systematic Review

BACKGROUND

Anxiety is common in patients with coronary heart disease (CHD) and is associated with an increased risk for adverse outcomes. There has been a relative paucity of studies concerning treatment of anxiety in patients with CHD.

OBJECTIVE

We conducted a systematic review to organize and assess research into the treatment of anxiety in patients with CHD.

METHODS

We searched CCTR/CENTRAL, MEDLINE, EMBASE, PsycINFO, and CINAHL for randomized clinical trials conducted before October 2016 that measured anxiety before and after an intervention for patients with CHD.

RESULTS

A total of 475 articles were subjected to full text review, yielding 112 publications that met inclusion criteria plus an additional 7 studies from reference lists and published reviews, yielding 119 studies. Sample size, country of origin, study quality, and demographics varied widely among studies. Most studies were conducted with nonanxious patients. The Hospital Anxiety and Depression Scale and State-Trait Anxiety Inventory were the most frequently used instruments to assess anxiety. Interventions included pharmacological, counseling, relaxation-based, educational, or "alternative" therapies. Forty (33% of total) studies reported that the interventions reduced anxiety; treatment efficacy varied by study and type of intervention. Elevated anxiety was an inclusion criterion in only 4 studies, with inconsistent results.

CONCLUSION

Although there have been a number of randomized clinical trials of patients with CHD that assessed anxiety, in most cases anxiety was a secondary outcome, and only one-third found that symptoms of anxiety were reduced with treatment. Future studies need to target anxious patients and evaluate the effects of treatment on anxiety and relevant clinical endpoints.

Assessment of response shift using two structural equation modeling techniques

OBJECTIVE

To identify response shift using two structural equation modeling (SEM) techniques.

STUDY DESIGN AND SETTING

Hypertensive patients (n = 909) with coronary artery disease (CAD) completed SF-36 surveys at both baseline and 1-year follow-up. Response shift was identified using Oort and Schmitt SEM techniques. The type of response shift linked to changes in various parameters of the SEM measurement model is defined differently for both SEM approaches. Effect sizes were calculated for the impact of response shift on the change of SF-36 domain scores when using the Oort approach.

RESULTS

Both Oort and Schmitt SEM approaches identified response shift only in the SF-36 physical functioning (PF) scale. The effect size of recalibration on the change of PF domain scores when using the Oort approach was -0.12.

CONCLUSION

This study showed that hypertensive patients with CAD experienced a response shift over a 1-year period. Both the SEM approaches identified response shift (uniform recalibration using the Oort approach and recalibration using the Schmitt approach); however, both approaches use different parameters to define and test response shift. We found that either the variation in analytic methods or the sample used may influence the identification and type of response shift.

Psychiatric disorders and coronary heart disease in women -- a still neglected topic: review of the literature from 1971 to 2000

BACKGROUND

Coronary heart disease (CHD) is the leading cause of death in women aged over 40 years in the United States, for whom it conveys a worse prognosis than for men. Recently, psychosocial factors have been understood to represent significant risk factors for developing CHD, as well as having a worse outcome with established CHD. However, these factors are often overlooked, in particular comorbid psychiatric disorders and psychiatric symptoms. To summarize the current knowledge in this interdisciplinary field, the authors conducted a review of CHD in women, taking into account psychosocial aspects, in particular psychiatric disorders.

METHODS

Medline searches using the keywords 'psychiatric disorder' and 'coronary heart disease' and 'women', and 'psychiatric disorder' and 'cardiac disease' and 'women', were performed, covering the time span from the beginning of the Medline database until January 1, 2001.

RESULTS

Quoted items included depression, panic disorder, generalized anxiety disorder, mitral valve prolapse, chest pain, anorexia nervosa, menopause, alcohol abuse, cocaine use, sleep disorder, sexual dysfunction, hostility and type A behavior, as well as other psychosocial aspects. There is accumulating evidence of significant associations between psychosocial factors, in particular psychiatric disorders and psychiatric symptoms, and the development and recurrence of CHD in women.

CONCLUSIONS

However, in summary, the topic still seems to be neglected. Future research into psychiatric disorders and psychiatric symptoms and CHD in women is strongly required, and the focus on women exclusively is underlined.

The course of anxiety and depression in patients undergoing coronary artery bypass graft surgery

A semilongitudinal study was designed to follow-up the course of anxiety and depression in patients undergoing coronary artery bypass graft (CABG) surgery. The focus was on possible effects of gender and age on variations in both mean level and interindividual differences over time. At two timepoints before and two after surgery, 217 patients completed self-report questionnaires. Multivariate testing revealed an overall decrease in mean levels of anxiety and depression in the postoperative period but different trends for men and women. Compared with men, women reported more anxiety and depression, both pre- and postoperatively, but showed a relatively stronger decrease in the early postoperative period. Regarding variations in interindividual differences over time, multivariate testing revealed different trends of depression for men and women. Women appeared to be most homogeneous in the early days after surgery, whereas interindividual differences for men showed a stable trend.

Psychosocial factors of coronary heart disease in women: a review

Although coronary heart disease is the leading cause of death in women in most industrialized countries, much less research has been carried out on this topic to date than in men. This article gives an overview of psychosocial factors of coronary heart disease in women, focussing on psychosocial risk factors for coronary heart disease in women such as socioeconomic status, employment status, chronic troubling emotions, social support and bereavement/widowhood. A second focus lies on psychosocial adjustment in women once coronary heart disease has become manifest, i.e. well-being, return to work, sexual activity and rehabilitation outcome after a myocardial infarction or coronary artery bypass grafting. Via a computerized literature research in Medline, Psychlit and Sociofile over the period 1980-1994 all studies on these topics were collected and reviewed. Comparatively more research has been undertaken on psychosocial risk factors for than on psychosocial adjustment to coronary heart disease in women. Low social class, low educational attainment, the double loads of work and family, chronic troubling emotions and lack of social support emerge as documented risk factors in women. Regarding psychosocial adjustment to coronary heart disease in women, there is a paucity of data, and studies including large samples of women and adjusting for gender are warranted. Psychosocial adjustment in women after a myocardial infarction seems to be worse than in men, whereas results on adjustment after coronary artery bypass grafting are inconclusive. Return to work rates after myocardial infarction or coronary artery bypass grafting are significantly lower in women than in men. Data on sexual activity of women after myocardial infarction or coronary artery bypass grafting are scarce, and there seems to be a complete lack of physician counseling on this topic. Studies on rehabilitation outcome report poorer programme uptake, poorer adherence and significantly higher drop-out rates for women than for men, yet those women who complete cardiac rehabilitation show the same or even greater functional improvements than men.
