Effectiveness of cognitive-behavioral therapy on perceived stress among patients undergoing percutaneous coronary intervention: A randomized controlled trial.

Purpose: This study aimed to determine the effectiveness of cognitive-behavioral therapy on perceived stress of patients undergoing percutaneous coronary intervention (PCI).

Design And Methods: This was a randomized clinical trial in which the patients under coronary intervention were allocated to two groups, intervention and control by using block randomization. The experiment group received eight sessions of cognitive-behavioral therapy. The patients' perceived stress was measured before, immediately, and 1-month post ntervention.

Findings: The results showed the perceived stress scores changed significantly in the intervention group compared with the control group immediately and 1 month after the intervention. Therefore, the perceived stress level significantly reduced in the patients of the intervention group (p < 0.001).

Practice Implications: Cognitive-behavioral therapy significantly reduced perceived stress in patients undergoing PCI.
