ObjectiveTo explore the development characteristics and influencing factors of short-term fatigue in patients with acute myocardial infarction(AMI).

MethodsA total of 103 patients with AMI were selected from a tertiary grade A hospital by convenience sampling method.The short-term fatigue status of patients at discharge and after 1-3 months of discharge were evaluated, and the development characteristics and categories of short-term fatigue were determined.The single factor and multiple factor logistic regression analysis were used to determine the influencing factors of each type of fatigue.

ResultsThe proportions of developmental longitudinal categories of AMI patients fatigue were 40.78%(42/103), 48.54%(50/103) and 10.68%(11/103) in significant remission group, slow remission group and no remission group, respectively.The gender, KILLIP grade and perceived social support were statistically significant among different groups of fatigue trajectory(P < 0.05 to P < 0.01).The anxiety(GAD-2), depression(PHQ-2) and insomnia(AIS) before and after discharge were compared among different groups of fatigue trajectory, and the differences were statistically significant(P < 0.05 to P < 0.01).The results of multiple logistic regression analysis showed that the male, KILLIP grade Ⅰ, and perceived social support were the protective factors, while the insomnia after 3 months of discharge was the risk factor in the slow remission group.The perceived social support was a protective factor, while the anxiety at discharge, depression at discharge and insomnia after 3 months of discharge were the risk factors in the significant remission group.

ConclusionsIt is suggested that in the future clinical nursing work, the targeted nursing should be carried out according to the characteristics and types of fatigue development of patients with myocardial infarction to prevent the occurrence of persistent fatigue.
