Latent profile analysis and related factors of post-traumatic growth in young and middle-aged patients with acute myocardial infarction.

• There are three potential categories of post-traumatic growth in young and middle-aged acute myocardial infarction patients: Malgrowth group, Good growth group, Excellent growth group. • The elderly and the spouseless are high-risk groups for post-traumatic growth failure, and we should pay special attention to them. • Health care providers may consider providing targeted interventions based on different types of patients to improve patient outcomes. AMI incidence in young and middle-aged patients is increasing year by year, and such patients are prone to negative emotions after illness, which affects health outcomes. However, post-traumatic growth can bring about positive changes in the patient, which is beneficial to their recovery. This study aimed to understand the different types of post-traumatic growth characteristics and their related factors in young and middle-aged patients with acute myocardial infarction to help find precise intervention measures. This was a cross-sectional study. Self-reported questionnaires were used to assess general demographic characteristics, post-traumatic growth, and rumination. The mean of the five dimensions of the Post-traumatic Growth Scale was used to perform a Latent profile analysis. A total of 312 participants, including 285 male and 27 female patients, with the mean age was 51.95±5.75. Latent profile analysis results showed that three-profile model was the most suitable. Three different profiles were named: the "Malgrowth group" (45.51%), the "Good growth group" (18.91%), and the "Excellent growth group" (35.58%). The related factors included rumination, age, monthly income, whether to return to work, marital status, residential address, classification of disease, and whether to perform PCI treatment (P<0.05). According to our results, the post-traumatic growth of young and middle-aged AMI patients can be divided into three profiles, and targeted intervention can be carried out for patients according to the determined patient profiles.
