Angina self-management plan and quality of life, anxiety and depression in post coronary angioplasty patients

Effectiveness of self-care program on the quality of life in patients with coronary artery disease undergoing cardiac rehabilitation: A Randomized clinical trial

BACKGROUND

Coronary artery disease (CAD) is a life-threatening condition that causes physical and psychological disorders and decreases patients' quality of life (QoL). Performing proper educational self-care program may lead to higher QoL in these patients. This study was performed to investigate the effectiveness of a self-care educational program on QoL in patients with CAD.

MATERIALS AND METHODS

This semi-experimental study was performed on 60 patients with CAD referred to the cardiac rehabilitation (CR) center of Vali Asr hospital in Qom, Iran, in 2018-2019. Patients were divided into control and intervention groups by randomized sampling. The self-care educational program was provided through lectures and booklet. Data collection was done using the "demographic and clinical data questionnaire," and "Seattle Angina questionnaire." Questionnaires were completed in both groups, before and at least 1 month after education. Analysis of the obtained data was performed using SPSS software (version 25), central indexes, Mann-Whitney test, and Wilcoxon test.

RESULTS

No significant differences were observed between the two groups for demographics characteristics and quality of life before the intervention. Before the self-care program, the mean score of the QoL in the intervention and control group were 56.14 ± 9.75 and 58.46 ± 11.71, respectively. After that, the mean score of the QoL in the intervention and control group were 59.25 ± 10.56 and 59.7 ± 13.33, respectively. The statistical analysis showed significant differences in the mean scores of QoL in the intervention group before and after the intervention (P < 0.05). However, no statistically significant differences were seen in the control group before and after the study (P > 0.05).

CONCLUSIONS

The self-care educational program improved the QoL in patients with CAD. Therefore, lectures and educational booklets should be considered by CR nurses.

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.

Translation and psychometric testing of the Farsi version of the Seattle angina questionnaire

Background

Angina pectoris causes substantial psychological and functional disabilities and adversely effects quality of life in patients. The aim of this study was to investigate the psychometric properties including validity and reliability of the Farsi version of the Seattle angina questionnaire.

Methods

The ‘forward-backward’ procedure was applied to translate this questionnaire from English to Farsi. The translated version of the Seattle angina questionnaire was assessed in terms of validity and reliability with a convenience sample of 200 patients suffering from angina pectoris who were recruited from the inpatient ward (post CCU) and outpatient department at two teaching hospitals in an urban area of Iran. Validity was assessed using content, face and construct validity. The calculation of the Cronbach’s alpha coefficient and the test-retest method helped with the assessment of reliability of the questionnaire’s five subscales. Construct validity of the questionnaire was evaluated using exploratory factor analysis.

Results

The results of exploratory factor analysis indicated a five-factor solution for the questionnaire including ‘physical limitation in middle to strenuous activities’, ‘physical limitation in slight activities’, ‘angina pattern and discomfort of treatment’, ‘treatment satisfaction’ and ‘disease perception’ that jointly accounted for 64.42% of variance observed. Convergent validity was mostly supported by the pattern of association between the Seattle angina questionnaire-Farsi version and the SF-36. Cronbach’s alpha of the subscales ranged from 0.60 to 0.86 and test-retest scores ranged from 0.79 to 0.97 indicating a good range of reliability.

Conclusions

The Seattle angina questionnaire-Farsi version had acceptable psychometric properties. Therefore, it can be used to assess health-related quality of life and assess the effects of different medical and nursing interventions on patients’ quality of life.

Quality of Life in Patients with Coronary Artery Disease and Panic Disorder: A Comparative Study

OBJECTIVES

The quality of life (QOL) of patients with coronary artery disease (CAD) is known to be impaired. Non-cardiac chest pain referrals are often under-diagnosed and untreated, and there are hardly any studies comparing the QOL of CAD and panic disorder related (non-cardiac) chest pain referrals (PDRC).

METHODS

We assessed the psychiatric morbidity and QOL of patients newly diagnosed with CAD (n = 40) at baseline and six weeks post-treatment and compared their QOL with patients with PDRC (n = 40) and age- and gender-matched healthy controls (n = 57). Psychiatric morbidity in the CAD group was assessed using the General Health Questionnaire (GHQ12) item, Hamilton Anxiety Scores (HAM-A), and Hamilton Depression Scores (HAMD). QOL measures were determined by the World Health Organization QOL questionnaire (brief) and Seattle Angina Questionnaire. The CAD group was treated with anti-ischemic drugs (nitrates, betablockers), antiplatelet drugs (acetylsalicylsalicylic acid), anticoagulants (low molecular weight heparin, clopidogrel), and managed for risk factors. The PDRC group was treated with selective serotonin reuptake inhibitors and anxiolytics.

RESULTS

Patients with panic disorder had a worse QOL than those with CAD and healthy controls in the physical domain and psychological domain (PDRC vs. CAD vs. healthy controls, p < 0.001). In the CAD group, smoking was associated with change in angina stability (p = 0.049) whereas other tobacco products were associated with change in angina frequency (p = 0.044). Psychiatric morbidity was present in 40.0% of patients with CAD. In the PDRC group, a significant correlation of HAM-A scores was noted in the physical (p = 0.000), psychological (p = 0.001), social (p = 0.006), and environment (p = 0.001) domains of QOL. Patients with panic disorder had a significant improvement in anxiety scores after treatment compared to baseline (HAM-A scores difference 21.0 [16.5-25.6]; p < 0.001).

CONCLUSIONS

Patients in the PDRC group had a worse QOL than those in the CAD and healthy control groups. This highlights the need for careful diagnosis and prompt treatment of panic disorder in these patients to improve their QOL. Additionally, smoking, the use of other tobacco products, and hypercholesterolemia were associated with angina symptoms in patients with CAD.
