Objective  To investigate the current status of acute psychological stress among patients with acute myocardial infarction after percutaneous coronary intervention (PCI).

Methods  A total of 150 patients with acute myocardial infarction who underwent PCI were selected as study subjects. The patients were surveyed through questionnaires usingBasic Information Questionnaire, the Stanford Acute Stress Response Questionnaire (SASRQ) and Comprehensive Quality of Life Assessment Questionnaire (GQOLI-74).

Results  The score of acute psychological stress in patients with acute myocardial infarction after PCI was (45.38±8.94). The acute psychological stress of patients was divided into three potential profile categories, namely low stress (C1 group, n=53), moderate stress disorder with high avoidance (C2 group, n=59), and severe stress disorder with repeated experience (C3 group, n=30). There were statistically significant differences in age, gender, residence style and chest pain score among the three groups (P < 0.05). The score of quality of life for patients with acute myocardial infarction after PCI was (194.67±34.95). The quality of life level of patients in C1 group was higher than that in the C2 and C3 groups, and the difference was statistically significant (P < 0.01). The quality of life level of patients in the C2 group was higher than that in the C3 group, and the difference was statistically significant (P < 0.05).

Conclusion  Clinical staff should identify the characteristics of different types of patients, attach importance to patients with a potential profile of repeated experiences of severe stress disorder, and carry out necessary psychological intervention in a timely manner to improve the subsequent treatment effect and prognosis of patients.
