The aim of this trial was to evaluate the Angina Plan (AP), a cognitive-behavioral nurse-facilitated self-help intervention against standard care (SC). A randomized controlled trial of 218 patients hospitalized with angina assessed participants predischarge and 6 months later. Data were collected during a structured interview using validated questionnaires, self-report, and physiological measurement to assess between group changes in mood, knowledge and misconceptions, cardiovascular risk, symptoms, quality of life, and health service utilization. The intention-to-treat (ITT) analysis found no reliable effects on anxiety and depression at 6 months. AP participants reported increased knowledge, less misconceptions, reduced body mass index (BMI), an increase in self-reported exercise, less functional limitation, and improvements in general health perceptions and social and leisure activities compared to those receiving SC. Sensitivity analysis excluding participants with high baseline depression revealed a statistical significant reduction in depression levels in AP compared to the SC participants. Analysis excluding participants receiving cardiac surgery or angioplasty removed the ITT effects on physical limitation, self-reported exercise and general health perceptions and the improvements seen in social and leisure activities, while adaptive effects on knowledge, misconceptions and BMI remained and between-group changes in depression approached significance. Initiating the AP in a secondary care setting for patients with new and existing angina produces similar benefits to those reported in newly diagnosed primary care patients. Further evaluation is required to examine the extent of observed effects in the longer term.
本试验的目的是评估由护士协助的认知行为自助干预方案——心绞痛方案(AP),并与标准护理(SC)进行对比。一项针对218名因心绞痛住院患者的随机对照试验,在患者出院前及6个月后对参与者进行了评估。在结构化访谈期间,通过使用经过验证的问卷、自我报告和生理测量来收集数据,以评估两组在情绪、知识和误解、心血管风险、症状、生活质量以及医疗服务利用方面的变化。意向性分析(ITT)发现,在6个月时对焦虑和抑郁没有可靠的影响。与接受标准护理的患者相比,参与心绞痛方案的患者报告称知识有所增加、误解减少、体重指数(BMI)降低、自我报告的运动量增加、功能受限减少,并且在总体健康认知以及社交和休闲活动方面有所改善。排除基线抑郁程度较高的参与者后的敏感性分析显示,与接受标准护理的参与者相比,心绞痛方案组的抑郁水平有统计学意义的降低。排除接受心脏手术或血管成形术的参与者后的分析消除了意向性分析对身体限制、自我报告的运动和总体健康认知的影响,以及在社交和休闲活动中观察到的改善,而对知识、误解和体重指数的适应性影响仍然存在,并且两组之间抑郁的变化接近显著水平。在二级护理环境中为新患和现患心绞痛的患者启动心绞痛方案,所产生的益处与新诊断的初级护理患者中报告的益处相似。需要进一步评估以检查长期观察到的效果的程度。
