BackgroundPatients after percutaneous coronary intervention （PCI） are prone to experience depression， which has been shown to significantly affect patients' quality of recovery in postoperative period. Resourcefulness plays an important role between stress and depression， yet there is insufficient research evidence on the predictive effect of intellectual resourcefulness levels on depressive symptoms among patients undergoing PCI.ObjectiveTo investigate the cross-lagged effect between level of resourcefulness and depressive symptoms among patients after PCI， so as to provide references for alleviating depressive symptoms in patients after PCI.MethodsA total of 363 patients who had undergone PCI in Tangshan Gongren Hospital from September to December 2019 were selected using random sampling technique. All participants were subjected to complete Chinese Resourcefulness Scale （CRS） and Chinese version of Cardiac Depression Scale （C-CDS） at both baseline and two years after PCI. A structural equation model was constructed to determine the cross-lagged effect between the level of resourcefulness and depressive symptoms in patients.ResultsMale patients scored higher on CRS （t=-19.871， P
