Digital CBT Effectively Reduces Post-Heart Attack Anxiety, Boosts Quality of Life
A new randomized study from Karolinska Institutet indicates that digital Cognitive Behavioral Therapy (CBT) effectively reduces cardiac-related anxiety and significantly improves the quality of life and physical function in patients post-heart attack.
Published in the Journal of the American College of Cardiology, this research compared digital CBT with standard medical care, offering a promising avenue for cardiac recovery.
Addressing Persistent Cardiac Anxiety
Following a heart attack, many individuals experience persistent heart-related anxiety. This often includes a fear of future cardiac events or an avoidance of crucial activities like physical exercise, which are vital for rehabilitation and overall well-being.
The study included 96 participants who had experienced a heart attack at least six months prior and exhibited significant cardiac-related anxiety.
The Randomized Study Design
Participants were randomly divided into two distinct groups for the study:
- One group received eight weeks of digital, exposure-based CBT.
- The other group continued with standard medical follow-up without additional psychological treatment.
The digital CBT program involved tailored exercises designed to help participants gradually confront and approach situations and heart-related symptoms they had previously avoided due to fear. All participants completed symptom self-assessments before and after the treatment period to evaluate changes.
Positive Outcomes: Reduced Anxiety and Enhanced Function
The results were compelling. The digital CBT group experienced significantly greater improvements in quality of life and notable reductions in heart-related anxiety compared to the control group at the three-month follow-up. Remarkably, these improvements remained stable for up to one year post-treatment.
Beyond psychological benefits, the treatment group also demonstrated greater improvements in physical functioning. Participants reported less hindrance in their daily lives and an increased engagement in physical activity, indicating a more robust recovery.
Expert Perspectives
Josefin Särnholm, a licensed psychologist and researcher at Karolinska Institutet, highlighted the method's impact:
"The method targets the reduction of fear associated with cardiac symptoms, enabling patients to resume activities previously avoided, thereby improving quality of life."
Amanda Johnsson, a licensed psychologist and doctoral student at Karolinska Institutet, underscored the broader implications:
"Cardiac-related anxiety is common after a heart attack and is treatable, with digital therapy offering broader patient access."
