Depression and anxiety are common among people who have experienced an acute coronary event (e.g., heart attack). Multidisciplinary cardiac rehabilitation programs often focus on reducing risk factors associated with future cardiac events, however, mental health interventions are not routinely available. Given known difficulties with access to mental health treatment, the present study sought to explore the efficacy and acceptability of an Internet-delivered cognitive behavioural therapy program (Cardiac Wellbeing Course) among participants who experienced an acute coronary event. The five-lesson course was delivered over eight weeks and was provided with brief weekly contact, via telephone and secure email with a guide. Participants were randomized to the Cardiac Wellbeing Course (n = 25) or waiting-list control group (n = 28). Symptoms were assessed at pre-treatment, post-treatment, and four-week follow-up. Completion rates (84%) and satisfaction ratings (95%) were high. Statistically significant between-group improvements were observed for the treatment group on primary measures of general anxiety (Cohen's d = 1.62; 67% reduction), depression (Cohen's d = 1.09; 61% reduction), and physical activity levels (Cohen's d = 0.27; 70% increase). Statistically significant improvements were also observed on secondary measures of distress (Cohen's d = 0.98; 51% reduction), cardiac anxiety (Cohen's d = 0.92; 34% reduction), and mental-health quality of life (Cohen's d = 0.23; 24% improvement). The changes were maintained at four-week follow-up. The current findings add to the existing literature and highlight the potential of Internet-delivered cognitive behavioural therapy programs among participants who have experienced an acute coronary event.

经历过急性冠脉事件（例如心脏病发作）的人中，抑郁和焦虑是常见的。多学科心脏康复计划通常侧重于减少与未来心脏事件相关的危险因素，但是，精神卫生干预措施并非常规可用。考虑到在获得心理健康治疗方面的已知困难，本研究旨在探讨经历急性冠脉事件的参与者通过互联网提供的认知行为治疗计划（心脏健康课程）的有效性和可接受性。这门为期五堂的课程历时八周，通过电话和安全的电子邮件以及指南，每周进行简短的联系。参加者被随机分配到心脏健康课程（n  = 25）或候补名单对照组（n  = 28）。在治疗前，治疗后和四周的随访中评估症状。完成率（84％）和满意度（95％）高。在一般焦虑的主要测量指标（Cohen d  = 1.62；减少67％），抑郁症（Cohen d  = 1.09；减少61％）和身体活动水平（Cohen d  = 0.27 ）的治疗组中，观察到治疗组之间的统计显着改善。;增加70％）。在二级求救指标（Cohen's d  = 0.98；减少51％），心脏焦虑（Cohen's d）上也观察到统计学上的显着改善 = 0.92; 减少34％），以及心理健康生活质量（科恩d  = 0.23；改善24％）。这些变化在四个星期的随访中得以维持。当前的发现增加了现有文献，并突出了在经历了急性冠脉事件的参与者中互联网提供的认知行为治疗计划的潜力。
