To evaluate the effect of video information given before cardiovascular magnetic resonance imaging on patient anxiety and to compare patient experiences of cardiovascular magnetic resonance imaging versus myocardial perfusion scintigraphy. To evaluate whether additional information has an impact on motion artefacts.
Cardiovascular magnetic resonance imaging and myocardial perfusion scintigraphy are technically advanced methods for the evaluation of heart diseases. Although cardiovascular magnetic resonance imaging is considered to be painless, patients may experience anxiety due to the closed environment.
A prospective randomised intervention study, not registered.
The sample (n = 148) consisted of 97 patients referred for cardiovascular magnetic resonance imaging, randomised to receive either video information in addition to standard text-information (CMR-video/n = 49) or standard text-information alone (CMR-standard/n = 48). A third group undergoing myocardial perfusion scintigraphy (n = 51) was compared with the cardiovascular magnetic resonance imaging-standard group. Anxiety was evaluated before, immediately after the procedure and 1 week later. Five questionnaires were used: Cardiac Anxiety Questionnaire, State-Trait Anxiety Inventory, Hospital Anxiety and Depression scale, MRI Fear Survey Schedule and the MRI-Anxiety Questionnaire. Motion artefacts were evaluated by three observers, blinded to the information given. Data were collected between April 2015-April 2016. The study followed the CONSORT guidelines.
The CMR-video group scored lower (better) than the cardiovascular magnetic resonance imaging-standard group in the factor Relaxation (p = .039) but not in the factor Anxiety. Anxiety levels were lower during scintigraphic examinations compared to the CMR-standard group (p < .001). No difference was found regarding motion artefacts between CMR-video and CMR-standard.
Patient ability to relax during cardiovascular magnetic resonance imaging increased by adding video information prior the exam, which is important in relation to perceived quality in nursing. No effect was seen on motion artefacts.
Video information prior to examinations can be an easy and time effective method to help patients cooperate in imaging procedures.
评估心血管磁共振成像前提供视频信息对患者焦虑的影响，并比较心血管磁共振成像与心肌灌注闪烁成像的患者体验。评估额外信息是否会对运动伪影产生影响。
心血管磁共振成像和心肌灌注闪烁成像都是评估心脏病的先进技术方法。虽然心血管磁共振成像被认为是无痛的，但由于封闭的环境，患者可能会感到焦虑。
前瞻性随机干预研究，未注册。
样本（n=148）由 97 名接受心血管磁共振成像检查的患者组成，随机分为接受附加视频信息（CMR-video/n=49）或仅接受标准文本信息（CMR-standard/n=48）的两组。第三组接受心肌灌注闪烁成像（n=51）的患者与心血管磁共振成像标准组进行比较。焦虑程度在检查前、检查后立即和 1 周后进行评估。使用了 5 个问卷：心脏焦虑问卷、状态-特质焦虑量表、医院焦虑和抑郁量表、MRI 恐惧调查量表和 MRI 焦虑问卷。运动伪影由三名观察者评估，观察者对所提供的信息不知情。数据收集于 2015 年 4 月至 2016 年 4 月之间。该研究遵循 CONSORT 指南。
CMR-video 组在 Relaxation（放松）因子上的得分低于（更好）CMR-standard 组（p=0.039），但在 Anxiety（焦虑）因子上没有差异。与 CMR-standard 组相比，闪烁成像检查期间的焦虑水平较低（p<0.001）。CMR-video 和 CMR-standard 之间在运动伪影方面没有发现差异。
在检查前增加视频信息可提高患者在心血管磁共振成像过程中的放松能力，这对于护理质量的感知很重要。对运动伪影没有影响。
检查前的视频信息可以是帮助患者配合成像过程的一种简单且有效的方法。
