How to reduce stress and anxiety in patients undergoing cardiac catheterization?

Stress Management in Pre- and Postoperative Care Amongst Practitioners and Patients in Cardiac Catheterization Laboratory: A Study Protocol

Background

As the number of cardiac diseases continuously increases within the last years in modern society, so does cardiac treatment, especially cardiac catheterization. The procedure of a cardiac catheterization is challenging for both patients and practitioners. Several potential stressors of psychological or physical nature can occur during the procedure. The objective of the study is to develop and implement a stress management intervention for both practitioners and patients that aims to reduce the psychological and physical strain of a cardiac catheterization.

Methods

The clinical study (DRKS00026624) includes two randomized controlled intervention trials with parallel groups, for patients with elective cardiac catheterization and practitioners at the catheterization lab, in two clinic sites of the Ernst-von-Bergmann clinic network in Brandenburg, Germany. Both groups received different interventions for stress management. The intervention for patients comprises a psychoeducational video with different stress management technics and additional a standardized medical information about the cardiac catheterization examination. The control condition includes the in hospitals practiced medical patient education before the examination (usual care). Primary and secondary outcomes are measured by physiological parameters and validated questionnaires, the day before (M1) and after (M2) the cardiac catheterization and at a postal follow-up 6 months later (M3). It is expected that people with standardized information and psychoeducation show reduced complications during cardiac catheterization procedures, better pre- and post-operative wellbeing, regeneration, mood and lower stress levels over time. The intervention for practitioners includes a Mindfulness-based stress reduction program (MBSR) over 8 weeks supervised by an experienced MBSR practitioner directly at the clinic site and an operative guideline. It is expected that practitioners with intervention show improved perceived and chronic stress, occupational health, physical and mental function, higher effort-reward balance, regeneration and quality of life. Primary and secondary outcomes are measured by physiological parameters (heart rate variability, saliva cortisol) and validated questionnaires and will be assessed before (M1) and after (M2) the MBSR intervention and at a postal follow-up 6 months later (M3). Physiological biomarkers in practitioners will be assessed before (M1) and after intervention (M2) on two work days and a two days off. Intervention effects in both groups (practitioners and patients) will be evaluated separately using multivariate variance analysis.

Discussion

This study evaluates the effectiveness of two stress management intervention programs for patients and practitioners within cardiac catheter laboratory. Study will disclose strains during a cardiac catheterization affecting both patients and practitioners. For practitioners it may contribute to improved working conditions and occupational safety, preservation of earning capacity, avoidance of participation restrictions and loss of performance. In both groups less anxiety, stress and complications before and during the procedures can be expected. The study may add knowledge how to eliminate stressful exposures and to contribute to more (psychological) security, less output losses and exhaustion during work. The evolved stress management guidelines, training manuals and the standardized patient education should be transferred into clinical routines.

A quasi-experimental study examining QR code-based video education program on anxiety, adherence, and satisfaction in coronary angiography patients

Background: QR (quick response) codes are a promising tool for health education, however effects of QR code application in providing peri-procedure education to patients with coronary angiography is unclear.Aim/Objective: This study investigated the effect of a QR code-based video education program on anxiety, adherence, and satisfaction in Chinese coronary angiography patients.Material and Methods: This prospective controlled clinical trial included 335 patients undergoing coronary angiography, including 166 patients in the experimental group and 169 patients in the control group. On the day before coronary angiography, patients in the experimental group had access to and could watch an educational video on their smartphones by scanning a QR code for multiple times, while patients in the control group watched the same video on a tablet once only. The primary outcome was anxiety assessed using the Chinese State Anxiety Inventory (C-SAI). Adherence to instructions and patient satisfaction with the information delivery method were also evaluated.Results: The C-SAI scores improved in the experimental group compared to the control group (F = 9.8, P < 0.001) over time. There is a significant difference in the changes of anxiety scores from baseline to pre-procedure (P < 0.001) and post-procedure (P < 0.01) between the two groups. Individuals in the experimental group showed better adherence to instructions on removing dentures and jewelry, and taking medicines before the procedure (P < 0.05), and limb activity, water consumption, and diet after the procedure (P < 0.001).Conclusion: Patient education programs on smartphone that can be accessed multiple times by scanning a QR code can be an effective and convenient approach to reducing anxiety and enhancing adherence to instructions among Chinese coronary angiography patients. Hospitals and clinicians should consider more investments in developing such patient education programs and also help improve ehealth literacy.

Neutrophil count as the centerpiece in the joined association networks of inflammatory and cell damage markers, and neuroendocrine stress markers in patients with stable angina pectoris following stenting

Objective

The primary aim of this study was to examine whether markers of cell damage and of the psycho-neuroendocrino-inflammatory/immune (PNI) system could be associated in patients with stable coronary artery disease (CAD) on the next day following percutaneous coronary intervention (PCI).

Materials and methods

Blood samples of 23 patients (18 men and five women, mean age 62.9 ± 10.6 years), were collected immediately before (pre-PCI), immediately after (post-PCI), and on the day following PCI (1d-PCI). Lactoferrin, LL-37 and interleukin-6 (IL-6) were assayed in plasma, in addition to cortisol and chromogranin A (CgA), as well as CK, ASAT and ALAT. Total and differential leukocyte counts were also analysed.

Results

At all the three time points, the monocyte fractions, the monocyte-to-lymphocyte and the neutrophil-to-lymphocyte ratios and CgA levels were elevated. We detected significant peri-procedural changes in the plasma levels of our PNI markers: IL-6 (p<0.05), lactoferrin, LL-37 (both: p <0.0001), CgA, (p<0.05), and cortisol (p<0.01). On the first day after PCI, highly significant associations were found of ASAT with IL-6 and neutrophil count (both: r>0.75, p<0.0001), and of CgA with neutrophil count and monocyte count (both: r>0.79, p<0.0001); furthermore, cortisol was also associated with neutrophil count (r>0.7, p<0.0001).

Conclusions

The findings suggest that myocardial damage could correlate not only with an inflammatory reaction but, via neutrophil count, also with increased level of stress in stable CAD after PCI. Furthermore, 1d-PCI neutrophil count may serve as an easy-to-obtain integrative PNI measure in stable CAD.

Educational Video Intervention Effects on Periprocedural Anxiety Levels Among Cardiac Catheterization Patients: A Randomized Clinical Trial

Purpose: To explore the effectiveness of an educational video intervention in lowering periprocedural anxiety among Jordanian patients hospitalized for cardiac catheterization (CATH). There are many potential reasons of anxiety related to CATH including involvement of the heart and the actual test procedure. Methods: A randomized controlled trial took place in a specialized heart institute in Jordan. The sample size was 186 patients who had undergone CATH procedure. Patients anxiety levels were measured by physiological parameters of anxiety (blood pressure, heart rate, and respiratory rate) and by the Spielberger State Anxiety Inventory (SAI). Results: After video education, there was a significant difference in periprocedural perceived anxiety between the groups: preprocedural anxiety levels (M = 39.03, SD = 5.70) for the experimental group versus (M = 49.34, SD = 6.00) for the control, p < .001, and postprocedural perceived anxiety for the experimental group (M = 29.18, SD = 5.42) versus (M = 41.73, SD = 5.41) for the control. Conclusion: Providing an educational video intervention about CATH may effectively decrease periprocedural anxiety levels.

Relationships between coronary angiography, mood, anxiety and insomnia

The purpose of this study was to investigate and compare the anxiety, depression and insomnia levels in the pre- and post-coronary angiography in patients undergoing elective coronary angiography due to suspected coronary artery disease. This prospective cross-sectional study consisted of 120 patients consecutively underwent coronary angiogram (CAG) between January and August 2014 in Departments of Cardiology. The mean age was 57.49 (SD±9.73), and 58.3% of the sample were women. The Hospital Anxiety and Depression Scale, Profile of Mood States Scale, Spielberger's State-Trait Anxiety Inventory, and Insomnia Severity Index were used. Patients were subsumed under 2 groups as normal and critical according to the presence or the absence of visually severe stenosis in at least one coronary artery. Subjects with significant stenosis had greater mean scores on depression-dejection and anger-hostility sub-scales of the POMS in the post-angiography than pre-angiography scores. We found that older age and having a physical illness significantly contributed to the risk of having significant stenosis in coronary vasculature. Subjects with severe coronary artery stenosis scored higher on depression-dejection and anger-hostility sub-scales at the post-angiography time period relative to pre-angiography scores. Trait and state anxiety levels were found to be moderate higher in both groups.

ACTH- and cortisol-associated neutrophil modulation in coronary artery disease patients undergoing stent implantation

Background

Psychosocial stress and activation of neutrophil granulocytes are increasingly recognized as major risk factors of coronary artery disease (CAD), but the possible relationship of these two factors in CAD patients is largely unexplored. Activation of neutrophils was reported to be associated with stenting; however, the issue of neutrophil state in connection with percutaneous coronary intervention (PCI) is incompletely understood from the aspect of stress and its hypothalamic-pituitary-adrenal axis (HPA) background. Thus, we aimed to study cortisol- and ACTH-associated changes in granulocyte activation in patients undergoing PCI.

Methodology/Principal Findings

Blood samples of 21 stable angina pectoris (SAP) and 20 acute coronary syndrome (ACS) patients were collected directly before (pre-PCI), after (post-PCI) and on the following day of PCI (1d-PCI). Granulocyte surface L-selectin, CD15 and (neutrophil-specific) lactoferrin were analysed by flow cytometry. Plasma cortisol, ACTH, and lactoferrin, IL-6 were also assayed. In both groups, pre- and post-PCI ratios of lactoferrin-bearing neutrophils were relatively high, these percentages decreased substantially next day; similarly, 1d-PCI plasma lactoferrin was about half of the post-PCI value (all p≤0.0001). Post-PCI ACTH was reduced markedly next day, especially in ACS group (SAP: p<0.01, ACS: p≤0.0001). In ACS, elevated pre-PCI cortisol decreased considerably a day after stenting (p<0.01); in pre-PCI samples, cortisol correlated with plasma lactoferrin (r∼0.5, p<0.05). In 1d-PCI samples of both groups, ACTH showed negative associations with the ratio of lactoferrin-bearing neutrophils (SAP: r = −0.601, p<0.005; ACS: r = −0.541, p<0.05) and with plasma lactoferrin (SAP: r = −0.435, p<0.05; ACS: r = −0.609, p<0.005).

Conclusions/Significance

Pre- and post-PCI states were associated with increased percentage of activated/degranulated neutrophils indicated by elevated lactoferrin parameters, the 1d-PCI declines of which were associated with plasma ACTH in both groups. The correlation of plasma cortisol with plasma lactoferrin in the extremely stressed ACS before stenting, however, suggests an association of cortisol with neutrophil activation.

Effects of music therapy on intravitreal injections: a randomized clinical trial

PURPOSE

To investigate the effects of music therapy on anxiety, perceived pain, and satisfaction in patients undergoing intravitreal injections in the outpatient setting.

METHODS

This is a randomized clinical trial. Seventy-three patients were recruited from the retina clinic at 1 institution and randomized into a music therapy (n=37) or control (n=36) group. Prior to injection, patients completed the state portion of the Spielberger State Trait Anxiety Inventory (STAI-S). The music therapy group listened to classical music through computer speakers while waiting for and during the injection. The control group underwent the injection in the same setting without music. Afterward, all patients completed another STAI-S and a satisfaction and pain questionnaire. The main outcome measures were objective anxiety derived from STAI-S scores and subjective pain and anxiety from the post procedure questionnaire.

RESULTS

The music therapy group had a greater decrease in anxiety than the control group (P=0.0480). Overall, 73% of all patients requested music for future injections (P=0.0001). The music therapy group (84%) requested music in future injections more frequently than the control group (61%) (P=0.0377). Both groups reported similar levels of pain (P=0.5879).

CONCLUSIONS

Classical music before and during intravitreal injections decreases anxiety in patients without decreasing pain. Most patients desire to have music during future injections. Music therapy is a low-cost, easy, safe intervention that reduces anxiety during intravitreal injections in the outpatient setting.
