Effect of Comprehensive Psychological Intervention on Negative Emotions and Quality of Life in Patients with Acute Myocardial Infarction

Although acute myocardial infarction (AMI) currently has a high survival rate, the treatment and prognosis are still diffuse negative life events for patients, which will affect their quality of life (QOL) and psychological health. Based on an integrated physiological-psychological-social-medical model, it is necessary to design an intervention program for safeguarding the physical and mental health of AMI patients.This study aimed to explore the influence of psychological intervention on negative emotions and QOL of AMI patients using a randomized controlled trial (RCT) design.Based on convenience sampling and double-blinded group assignment, 101 patients from August 2019 to January 2020 were randomly divided into 2 groups. An intervention group received comprehensive psychological intervention, while a control group received general supportive nursing. Both groups answered questionnaires before and after the intervention, including assessments of anxiety, depression, and QOL.Before the intervention, there were no significant differences between the groups. After intervention, anxiety and depression in the intervention group (n = 48) were significantly lower (P < 0.001) and QOL was markedly improved (P < 0.05) compared to that of the control group (n = 53).Comprehensive psychological intervention contributed to ameliorate negative emotions, enhance confidence in treatment, and improve the QOL of AMI patients.
