Effects of Virtual Reality on Pain, Anxiety, Patient Satisfaction in Coronary Angiography: A Randomized Trial.

BACKGROUND: Since patients are conscious during the coronary angiography procedure, they may experience pain and anxiety regarding possible complications and an uncertain outcome. AIM: This study was conducted to determine the effects of virtual reality application on pain severity, anxiety level, and patient satisfaction in patients who undergo coronary angiography. METHOD: This randomized controlled study was conducted with a total of 70 patients, including 35 patients in the intervention and 35 patients in the control group. Apart from their routine treatment, virtual reality glasses application was used in the intervention group patients during the procedure. The patients in the control group were given only routine treatment. Data were collected by using "Descriptive Information Form", "Visual Analogue Scale (VAS)", Anxiety Assessment Scale (AAS), "Physiological Symptoms of Anxiety Follow-up Form", and "Virtual Reality Glass Application Satisfaction Form". RESULTS: Mean post-intervention scores of VAS, AAS, heart rate, diastolic and systolic blood pressure, respiratory rate of the intervention group decreased significantly compared with the control group, while O2 saturation value was found to increase significantly. CONCLUSIONS: In this study, it was found that virtual reality application was effective in reducing pain and anxiety, increasing patient satisfaction, and normative regulation of vital signs in patients who undergo coronary angiography.

Efficacy of education delivery through multimedia and text messaging on the psychological parameters of patients scheduled for coronary angiography: a single-blind randomized controlled clinical trial.

BACKGROUND: Angiography is a highly effective invasive method for diagnosing coronary artery diseases but can lead to certain psychological problems such as stress, anxiety, and depression. This study aimed to compare the effects of education delivery through multimedia DVD content or text messaging in comparison with conventional printed pamphlets on the psychological parameters of patients scheduled for angiography. METHODS: This study was a randomized controlled clinical trial. We used the convenience sampling method to select 120 patients who met the inclusion criteria among individuals who were scheduled for elective coronary angiography. The patients were randomly divided into three groups through the block randomization method. The necessary educational tips for before, during, and after the angiography procedure were delivered to the patients in interventional group 1 (n = 40) and interventional group 2 (n = 40) through text messages and a multimedia DVD, respectively. The control group received routine hospital education through pamphlets besides the opportunity for verbal discussions with nurses. All educational content was delivered to the patients four days before the scheduled day of angiography. The DASS-21 questionnaire, consisting of the three domains of stress, anxiety, and depression, was used to collect the data. The questionnaire was administered at the time of delivering the educational content as the pretest evaluation and 30 min after the angiography procedure as the posttest evaluation. SPSS software, version 18, was used for statistical analysis. RESULTS: There was no significant difference among the three groups of patients in terms of pretest DASS-21 scores. Conversely, the mean posttest scores in all DASS-21 domains were significantly lower among the patients receiving education via the multimedia DVD or text messaging in comparison with the control group (P < 0.001). However, there were no statistically significant differences between the mean scores in all domains between the participants in the DVD and text messaging groups. CONCLUSION: It seems that both DVDs and text messaging are more effective than conventional pamphlets in controlling the anxiety, stress, and stress of patients scheduled for elective coronary artery angiography.

Patient Preferences for Coronary CT Angiography with Stress Perfusion, SPECT, or Invasive Coronary Angiography.

Background Patient preference is pivotal for widespread adoption of tests in clinical practice. Patient preferences for invasive versus other noninvasive tests for coronary artery disease are not known. Purpose To compare patient acceptance and preferences for noninvasive and invasive cardiac imaging in North and South America, Asia, and Europe. Materials and Methods This was a prospective 16-center trial in 381 study participants undergoing coronary CT angiography with stress perfusion, SPECT, and invasive coronary angiography (ICA). Patient preferences were collected by using a previously validated questionnaire translated into eight languages. Responses were converted to ordinal scales and were modeled with generalized linear mixed models. Results In patients in whom at least one test was associated with pain, CT and SPECT showed reduced median pain levels, reported on 0-100 visual analog scales, from 20 for ICA (interquartile range [IQR], 4-50) to 6 for CT (IQR, 0-27.5) and 5 for SPECT (IQR, 0-25) (P < .001). Patients from Asia reported significantly more pain than patients from other continents for ICA (median, 25; IQR, 10-50; P = .01), CT (median, 10; IQR, 0-30; P = .02), and SPECT (median, 7; IQR, 0-28; P = .03). Satisfaction with preparation differed by continent and test (P = .01), with patients from Asia reporting generally lower ratings. Patients from North America had greater percentages of "very high" or "high" satisfaction than patients from other continents for ICA (96% vs 82%, respectively; P < .001) and SPECT (95% vs 79%, respectively; P = .04) but not for CT (89% vs 86%, respectively; P = .70). Among all patients, CT was preferred by 54% of patients, compared with 18% for SPECT and 28% for ICA (P < .001). Conclusion For cardiac imaging, patients generally favored CT angiography with stress perfusion, while study participants from Asia generally reported lowest satisfaction. © RSNA, 2019 Online supplemental material is available for this article.

Possible Effect of Video and Written Education on Anxiety of Patients Undergoing Coronary Angiography.

PURPOSE: The aim of this study was to investigate possible effects of video and written education on anxiety of patients undergoing coronary angiography. DESIGN: The study design was quasi-experimental. METHODS: This randomized controlled semitrial model included patients who underwent coronary angiography between October 2015 and May 2016 at the Department of Cardiology of a university hospital. The number of subjects determined by power analysis was 90 patients in three groups. Written education, video education, and control groups were included. Data were collected using personal information forms, State-Trait Anxiety Inventory, and physiological variables. FINDINGS: There was a statistically significant difference in the mean scores of state anxiety, satisfaction, and physiological variables after education, compared with baseline, in both patient and control groups (P < .005). CONCLUSIONS: Our study results suggest that education given by the nurse before the procedure reduces level of anxiety and affects physiological variables positively.

Impact of video on the understanding and satisfaction of patients receiving informed consent before elective inpatient coronary angiography: A randomized trial.

BACKGROUND: Appropriate information about the benefits and risks of invasive procedures is crucial, but limited data is available in this field. The aim of this study was to evaluate the incremental value of a short video about coronary angiography compared with standard information, in terms of patient understanding, satisfaction and anxiety. METHODS: This prospective multicenter study included patients admitted for scheduled coronary angiography, who were randomized to receive either standard information or video information by watching a three-dimensional educational video. After information was delivered, patients were asked to complete a dedicated 16-point information questionnaire, as well as satisfaction and anxiety scales. RESULTS: From 21 September to 4 October 2015, 821 consecutive patients were randomized to receive either standard information (n=415) or standard information with an added educational video (n=406). The information score was higher in the video information group than in the standard group (11.8±2.8 vs 9.5±3.1; P<.001). This result was consistent across age and education level subgroups. Self-reported satisfaction was also higher in the video information group (8.4±1.9 vs. 7.7±2.3; P<.001), while anxiety level did not differ between groups. The variables associated with a higher information score were the use of the educational video, younger age, higher level of education, previous follow-up by a cardiologist, prior information about coronary angiography and previous coronary angiography. CONCLUSIONS: In comparison with standard information, viewing a dedicated educational video improved patients' understanding and satisfaction before scheduled coronary angiography. These results are in favor of widespread use of this incremental information tool.

The effects of environmental factors in waiting rooms on anxiety among patients undergoing coronary angiography: A randomized controlled trial.

BACKGROUND: According to Florence Nightingale's hypothesis, the environment can play a central role in the healing of the patient's body and mind. The nurse should, therefore, strive to provide a healing and stress-reducing environment for patients about to undergo invasive procedures. AIMS: This study aimed to investigate the effects of environmental factors on anxiety as experienced by patients in waiting rooms prior to coronary angiography. METHODS: In this randomized controlled trial, 200 patients undergoing coronary angiography in an urban area of Iran were assigned randomly to the following intervention groups: (1) nature sounds; (2) nature sounds and daylight; (3) nature sounds, daylight, and colour enhancements; and (4) control. Portable monitors were used to measure the patients' physiological indices upon admission and 30 and 60 minutes thereafter. RESULTS: Patients who experienced environmental affecting interventions had significantly lower physiological indices of anxiety than the control group (P < 0.001). Some significance was demonstrated between the three interventions groups, with patients in the intervention group that experienced maximum environmental interventions demonstrating the most overall reduction in anxiety indices. CONCLUSION: Environmental factors were shown to have a positive effect on the indices of anxiety experienced by patients waiting for the procedure of coronary angiography; this is therefore an area of study and practice worthy of further development.

Effectiveness of Chinese Hand Massage on Anxiety Among Patients Awaiting Coronary Angiography: A Randomized Controlled Trial.

BACKGROUND: Anxiety is the most common negative emotion among the patients awaiting coronary angiography. The increased anxiety may exacerbate coronary heart disease symptoms and possibly contribute to complications during the procedure. Chinese hand massage is a nonpharmaceutical intervention that has been used in several clinical situations in China and might have beneficial effects on reducing anxiety before coronary angiography. OBJECTIVE: The aim of this study was to evaluate the effectiveness and safety of Chinese hand massage care on anxiety among patients awaiting coronary angiography. METHODS: One hundred eighty-five subjects awaiting coronary angiography in a single hospital in Fuzhou, China, between May 2012 and September 2012 were screened. One hundred eligible participants were recruited and randomly assigned into the control or Chinese hand massage group. The control group received the conventional therapies and care according to the guidelines, and those in the Chinese hand massage group received additional Chinese hand massage care in conjunction with the same conventional therapies and care as the control group. The anxiety scores (evaluated by using the Hamilton Anxiety Rating Scale), heart rate, blood pressure, quality of life (Short-Form Health Survey), and the adverse events were recorded at the baseline and after coronary angiography, respectively. RESULTS: The scores of Hamilton Anxiety Rating Scale in the Chinese hand massage group (11.78 [SD, 2.9]) had a statistically significant decrease compared with those in the control group (15.96 [SD, 3.4]) at post-procedure (P < .01). There was no statistically significant difference on blood pressure, heart rate, and Short-Form Health Survey at postangiography between the Chinese hand massage group and the control group. No adverse event was reported during the intervention period. CONCLUSIONS: Chinese hand massage effectively alleviated anxiety without any adverse effects among patients awaiting coronary angiography. Therefore, it might be recommended as a nonpharmacological nursing intervention. However, future study with a larger sample size is needed to further confirm the efficacy of Chinese hand massage intervention.

Randomized controlled trial of relaxation music to reduce heart rate in patients undergoing cardiac CT.

OBJECTIVES: To evaluate the heart rate lowering effect of relaxation music in patients undergoing coronary CT angiography (CCTA), pulmonary vein CT (PVCT) and coronary calcium score CT (CCS). METHODS: Patients were randomised to a control group (i.e. standard of care protocol) or to a relaxation music group (ie. standard of care protocol with music). The groups were compared for heart rate, radiation dose, image quality and dose of IV metoprolol. Both groups completed State-Trait Anxiety Inventory anxiety questionnaires to assess patient experience. RESULTS: One hundred and ninety-seven patients were recruited (61.9 % males); mean age 56y (19-86 y); 127 CCTA, 17 PVCT, 53 CCS. No significant difference in heart rate, radiation dose, image quality, metoprolol dose and anxiety scores. 86 % of patients enjoyed the music. 90 % of patients in the music group expressed a strong preference to have music for future examinations. The patient cohort demonstrated low anxiety levels prior to CT. CONCLUSION: Relaxation music in CCTA, PVCT and CCS does not reduce heart rate or IV metoprolol use. Patients showed low levels of anxiety indicating that anxiolytics may not have a significant role in lowering heart rate. Music can be used in cardiac CT to improve patient experience. KEY POINTS: • Relaxation music does not reduce heart rate in cardiac CT • Relaxation music does not reduce beta-blocker use in cardiac CT • Relaxation music has no effect on cardiac CT image quality • Low levels of anxiety are present in patients prior to cardiac CT • Patients enjoyed the relaxation music and this results in improved patient experience.

Mediation and moderation of the effects of watching the angiography screen on patients.

It has been reported that allowing patients to watch the coronary angiography screen during the procedure results in psychological benefits. This study aimed to investigate the roles of illness perceptions as mediators of this outcome and to examine whether individual differences in monitoring coping style moderated these effects. The experiment compared patients who were instructed to watch the monitor screen (n = 57) with those who were not (n = 51). Questionnaires were used to measure the research variables at one day and one month after the procedure. Results showed that watching the angiography screen increased patients' personal and treatment control perceptions that mediated changes in self-assessed health, risk perceptions, negative affect, general and diet outcome expectancies, and diet and physical activity intentions. The behavior-related outcomes were moderated by monitoring coping style. These findings illustrate the significance of illness perceptions, perceived control and monitoring coping style in achieving desirable outcomes among patients undergoing coronary angiography, and reveal opportunities for interventions using medical imaging technologies.

Patient satisfaction with coronary CT angiography, myocardial CT perfusion, myocardial perfusion MRI, SPECT myocardial perfusion imaging and conventional coronary angiography.

OBJECTIVES: To evaluate patient acceptance of noninvasive imaging tests for detection of coronary artery disease (CAD), including single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI), stress perfusion magnetic resonance imaging (MRI), coronary CT angiography (CTA) in combination with CT myocardial stress perfusion (CTP), and conventional coronary angiography (CCA). METHODS: Intraindividual comparison of perception of 48 patients from the CORE320 multicentre multinational study who underwent rest and stress SPECT-MPI with a technetium-based tracer, combined CTA and CTP (both with contrast agent, CTP with adenosine), MRI, and CCA. The analysis was performed by using a validated questionnaire. RESULTS: Patients had significantly more concern prior to CCA than before CTA/CTP (p < 0.001). CTA/CTP was also rated as more comfortable than SPECT-MPI (p = 0.001). Overall satisfaction with CT was superior to that of MRI (p = 0.007). More patients preferred CT (46%; p < 0.001) as a future diagnostic test. Regarding combined CTA/CTP, CTP was characterised by higher pain levels and an increased frequency of angina pectoris during the examination (p < 0.001). Subgroup analysis showed a higher degree of pain during SPECT-MPI with adenosine stress compared to physical exercise (p = 0.016). CONCLUSIONS: All noninvasive cardiac imaging tests are well accepted by patients, with CT being the preferred examination. KEY POINTS: • A variety of cardiac imaging tests is available without known patient preference • CTA/CTP shows a lower degree of concern than conventional coronary angiography • CTA/CTP shows higher overall satisfaction compared to stress perfusion magnetic resonance imaging • CTA/CTP is rated as more comfortable than SPECT-MPI • CTA/CTP is the preferred cardiac imaging test.

Life satisfaction, cardiovascular risk factors, unhealthy behaviours and socioeconomic inequality, 5 years after coronary angiography.

BACKGROUND: Five years after coronary angiography, life satisfaction (LS) among patients may be related to incidents of cardiovascular diseases, risk factors and unhealthy behaviours and socioeconomic conditions, but their respective influence remains unclear. Our aim is to analyze LS and its relationships with those factors. METHODS: Among the 4,391 patients initially contacted, 547 deaths were reported and 209 had an invalid address. In 2013-2014, 3,635 patients who underwent coronary angiography in 2008-2009 at the National Institute of Cardiac Surgery and Cardiological Intervention (INCCI) in Luxembourg were asked to complete a self-administered questionnaire assessing LS [1-10] and other variables. Data were analysed via multiple regression models adjusted initially on age, sex and income, and for a second time with the addition of all CVRF. RESULTS: LS of 1,289 volunteers (69.2 years) was 7.3/10. Most were men, Luxembourgish, employees and manual workers, had secondary education and an income of 36,000 euros or more per year. LS was lowest in female patients, and those with a low to middle income. Patients who lived in a couple had the best LS. Patients with a history in the previous 5 years of physical inactivity (regression coefficient: -0.903), angina pectoris (rc -0.843), obesity (rc -0.512), diabetes, or hypercholesterolemia, were more likely to have lower LS. The previous associations were mostly maintained on the second analysis, with the exceptions of diabetes and obesity. In addition, patients who stopped smoking because of peer pressure (rc -0.011) had a lower LS. CONCLUSIONS: The finding that LS was lowest among female patients calls for further research on symptoms, and potential risk factors. Also, certain patient profiles are linked with low LS: 'inclined abstainers' who intended to modify their behaviours, but could not do so, and 'disinclined abstainers' who had no intention of changing and were insufficiently concerned to do so. Patients who stopped smoking and perceived it as unpleasant also had low LS. 'Disinclined actors' were those patients who had to adjust their lifestyles, but were ambivalent about their intentions and the behaviour, which they continued. Health promotion programs would benefit from targeting factors that moderate the unfavourable intention-behaviour relationship and can help enhance LS.

[The sense of coherence in women undergoing coronary arteriography]. / Poczucie koherencji w grupie kobiet poddanych koronarografii.

AIM: The examination referred to two groups of female patients: with and without significant coronary stenoses in coronarography. There were two stages of the examination: before and 6-9 months after coronarography. The factor dividing patients into two groups: without significant atheromatosis and with coronary atheromatosis, was the result of invasive diagnostics of coronary heart disease. METHODS: The sense of coherence scale (SOC-29) and sociodemographic questionnaires were used to evaluate the condition of the two groups. RESULTS: In group of patients with irrelevant coronary stenoses statistically lower values of sense of comprehension were noticed in the first and the second examination and also sta- tistically lower values of sense of manage were observed, comparing to the group of patients with significant stenoses. The initial value of general coherence was comparable in both groups and did not significantly change in 6-9 months after coronarography. The characteristic parameters: lack of social support, intensity of depressiveness and anxiety before getting information about necessity of coronarography and worse education were connected with lower sense of coherence. CONCLUSIONS: The baseline strength of the total sense of coherence was not different between groups. Patients with no significant stenosis of coronary arteries demonstrate a lower sense of comprehensibility before and after the coronary arteriography and lower sense of manageability after the procedure compared to the group of patients with significant atherosclerotic lesions. No social support, tendency for depression and anxiety and lower level of education were associated with lower sense of coherence in both groups.

Diagnostic procedures, revascularization, and inpatient mortality after acute myocardial infarction in patients with schizophrenia and bipolar disorder.

OBJECTIVE: To investigate inpatient mortality and the use of invasive diagnostic and revascularization procedures after acute myocardial infarction (AMI) in people with schizophrenia and bipolar disorder. METHODS: A case-control study was nested within the first AMI episodes between 1996 and 2007 using nationwide data. Participants with schizophrenia or bipolar disorder were compared with a random sample of all other adults without severe mental illness. Inpatient mortality and receipt of cardiac catheterization, coronary arteriography, percutaneous transluminal coronary angioplasty, and coronary artery bypass graft were compared in logistic regression models after adjusting for demographic and health status, hospital type, and AMI complications. RESULTS: A total of 3361 adult patients who had incident AMI between 1996 and 2007 were identified. Patients with schizophrenia and bipolar disorder (n = 834; 24.8%) had a significantly decreased likelihood of catheterization (12.2% and 14.0%, respectively) and revascularization (9.0% and 12.8%, respectively) during the index AMI episode compared with controls (27.9% of whom received catheterization and 23.9% of whom received revascularizations). Inpatient mortality remained 2.68 times the rate in patients with schizophrenia (95% confidence interval = 1.73-4.15; p < .001) compared with controls after adjusting for intervention receipt among other covariates, but mortality was not significantly raised in patients with bipolar disorder. CONCLUSIONS: In a large national sample and in the context of a comprehensive free health service, patients with schizophrenia and bipolar disorder were substantially disadvantaged, being half as likely to receive catheterization or revascularization procedures after AMI. Further research is required to clarify the reasons for this.

Effects of a 360° virtual counselling environment on patient anxiety and CCTA process time: A randomised controlled trial.

INTRODUCTION: This study investigated whether a 360° virtual counselling environment (360°VCE) was more effective at decreasing patients' anxiety than routine standard of care counselling for patients undergoing coronary computed tomography angiography (CCTA), and if there was any difference in the process times for both of these groups. METHODS: A total of 86 patients underwent CCTA in this randomised controlled trial. Patients were randomly assigned to intervention and control groups. The 360°VCE was developed using spherical panoramic images and non-immersive 360° technology. The primary outcome, anxiety, was measured using the State-Trait Anxiety Inventory (STAI). The secondary outcome, CCTA process time, was measured from the time of arrival in the department until end of examination. RESULTS: Pre-scan anxiety was lower among patients in the 360°VCE group immediately before CCTA in comparison to patients in the control group (p = 0.015). Women demonstrated higher levels of anxiety than men in both groups. No between-group differences were discerned in CCTA process time. CONCLUSION: Access to 360°VCE can reduce patients' pre-CCTA anxiety levels. IMPLICATIONS FOR PRACTICE: The presented results can be used to improve patient counselling and care, reduce anxiety among patients undergoing CCTA, and optimise the CCTA examination procedure.

Anger rumination, social support, and cardiac symptoms in patients undergoing angiography.

OBJECTIVES: Socially isolated individuals report more cardiac symptoms, suffer increased cardiovascular morbidity and mortality, and experience higher levels of stress and anxiety than those with more effective support resources. However, the complex interactions of psychosocial factors implicated in the disease process remain to be fully elucidated. We sought to explore these relationships, with the addition of a novel psychosocial variable, anger rumination, which could be associated with increased cardiovascular risk. DESIGN: We examined the association of psychological stress, social support, and anger rumination, with surgical anxiety, self-reported cardiac symptoms, and angiographically documented coronary artery disease, using a correlational ex post facto design. METHODS: One hundred and one patients scheduled for elective coronary angiography completed questionnaires during the week prior to angiography. Disease severity was objectively assessed using the Gensini scoring system. RESULTS: Self-reported cardiac symptom severity was significantly correlated with higher perceived stress, less social support, and higher anger rumination, but none of the psychosocial variables predicted Gensini score. Social support partially mediated the relationship between anger rumination and surgical anxiety. Perceived stress mediated the relationship between anger rumination and cardiac symptoms. CONCLUSIONS: For patients awaiting angiography, stress, and lack of social support are important predictors of self-reported cardiac symptoms, irrespective of actual disease severity. Intervention could focus on reducing perceived stress by encouraging reappraisal and a support seeking, rather than a ruminative, anger coping style.

Effectiveness of respiratory-sinus-arrhythmia biofeedback on state-anxiety in patients undergoing coronary angiography.

AIM: This study is a report of a study conducted to evaluate the value of psychological assistance including respiratory-sinus-arrhythmia biofeedback training in its ability to reduce the level of anxiety in patients undergoing coronary angiography. BACKGROUND: Coronary angiography has been reported to cause anxiety and emotional stress. METHODS: Between March 2004 and January 2005, 212 patients undergoing routine elective coronary angiography for the evaluation of stable coronary artery disease were randomized into two groups. In the psychological support group (n = 106) a structured psychological conversation and respiratory-sinus-arrhythmia biofeedback training were offered prior to coronary angiography. In the control group (n = 106) standard care and information was provided without psychological support. State-anxiety was measured (scale 20-80) 1 day prior to and after coronary angiography, along with blood pressure and heart rate. FINDINGS: Prior to coronary angiography, state-anxiety was 54.8 +/- 11.5 (mean +/- SD) in the control group and 54.8 +/- 12.6 in the psychological support group. After coronary angiography, state-anxiety was 47.9 +/- 18.5 in the control group but 28.3 +/- 12.5 in the psychological support group (Wilcoxon rank sum test W = 7272, P < 0.001). Blood pressure was statistically significantly lower in the psychological support group prior to the intervention and the day after coronary angiography. CONCLUSION: Psychological support including respiratory-sinus-arrhythmia biofeedback is an effective and simple tool that could be used by nurses to reduce state-anxiety and emotional stress in patients undergoing coronary angiography.

Effect of peer support on patient anxiety during the coronary angiography or percutaneous coronary intervention perioperative period: a protocol for a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: The purpose of this study is to investigate the effect of peer support on patient anxiety during the perioperative period of coronary angiography or percutaneous coronary intervention (PCI). METHODS AND ANALYSIS: We will search the following databases (PubMed, Web of Science, EMBASE, Cochrane Library, CINAHL, Clinicaltrials.gov, WHO International Clinical Trials Registry Platform, Google Scholar, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data) from the date of database inception to January 2019. Only randomised controlled trials will be included. For the data analysis, we will use RevMan V.5.3.5 software to evaluate the risk of bias, and the heterogeneity will be investigated using the Q statistic and P index. Additionally, the Grading of Recommendations Assessment, Development and Evaluation system will be used to assess the quality of evidence. ETHICS AND DISSEMINATION: No ethics approval will be required since this is a systematic review of published studies. We aim to report information regarding the effects of peer support on patient anxiety during the perioperative period of coronary angiography or PCI. This systematic review and meta-analysis will be submitted to a peer-reviewed journal for publication. PROSPERO REGISTRATION NUMBER: CRD42019123290.

Efficacy of complementary interventions for management of anxiety in patients undergoing coronary angiography: A rapid systematic review.

Coronary angiography (CAG) is an invasive and anxiety-provoking procedure for many patients. Psychological problems, especially anxiety, are the main concern of nurses taking care of these patients before the procedure. This rapid systematic review aimed to assess the efficacy of interventions for management of anxiety in patients undergoing CAG. In this study, all published, peer-reviewed, English-language interventional studies from 2009 to 2018 were identified in a search of Scopus, PubMed, and Google Scholar databases. The relevant studies were assessed using a quality assessment checklist. All included studies were assessed by 2 researchers. Finally, 15 studies with 1,312 participants that evaluated the effects of complementary methods on management of anxiety in patients undergoing CAG were included. The findings of this rapid systematic review suggested that complementary and nonpharmacological methods, such as music therapy, reflexology, Benson's relaxation technique, aromatherapy, guided imagery, and yoga, could be used effectively for management of anxiety in patients undergoing CAG.

The Effectiveness of Peer Group-Based Training on the Outcomes of Patients Undergoing Transradial Coronary Angiography.

INTRODUCTION: Coronary artery angiography using radial artery is one of the methods used for diagnosis of coronary artery disease, which causes physical and psychological problems in patients despite its precise and definite diagnosis. The present study is aimed at investigating the effect of peer group-based education on physical and psychological outcomes of patients undergoing coronary artery angiography through the radial artery. Methodology. The present clinical study was conducted on 60 patients undergoing coronary angiography through the radial artery in Vali-e-Asr educational hospital of Fasa during 2018 to 2019. The participants were divided into peer training and control groups (n = 30 in each group) using permutated block randomization. In the peer training group, the patients received the necessary precare training through peer training during and after angiography care. In the control group, the patients received the routine care by the nurse of the related ward. The peer group's stress, anxiety, and depression levels were evaluated before and after the training. Indeed, their comfort, tolerance, satisfaction, and pain levels were measured by a nurse after angiography at the time of entering the ward. Findings. The results indicated no significant difference between the two groups regarding the mean scores of stress, anxiety, and depression before the intervention (p > 0.05). After the intervention, however, there was a significant difference between the two groups concerning the mean score of anxiety (p < 0.05). Nonetheless, no significant difference was found between the two groups in terms of tolerance, comfort, satisfaction, and pain levels (p > 0.05). Finally, the level of pain decreased in both groups over time (p < 0.001). CONCLUSION: Peer group-based training was effective in decreasing the mean score of anxiety in the patients undergoing coronary angiography. Thus, this method is recommended to be utilized alongside other methods to train patients before coronary angiography due to its inexpensiveness and lack of side effects as well as not increasing the nurses' workload.
