What this trial studies

This study evaluates an online Cognitive Behavioral Therapy (CBT) program designed for patients recovering from Acute Coronary Syndrome (ACS) to reduce cardiac anxiety, improve quality of life, and encourage physical activity. Participants will be randomly assigned to either the internet-based CBT group or an active control group receiving internet-based cardiac lifestyle intervention. Both groups will receive weekly therapist support through online communication over an 8-week period. The study aims to determine the effectiveness of the online CBT protocol in alleviating anxiety and enhancing overall well-being in ACS patients.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce cardiac anxiety and improve the quality of life for patients recovering from ACS.

How similar studies have gone: Previous studies have shown promise in using online CBT for anxiety management, suggesting potential success for this approach.
