Abstract: Objective: To investigate the coping styles,strategies and coping ability in a group of patients undergoing percutaneous coronary intervention(PCI) for the first time due to coronary artery disease,and to discuss the correlation between coping styles and coping ability.Methods: One hundred and ten subjects,recruited by convenience sampling,were required to complete the questionnaire survey by Jalowiec coping scale,sense of coherence-13 and self-designed questionnaire about the patient's general information.Results: With the exception of emotive(P>0.05),the values of other 7 coping styles of patients after PCI were much higher than that before PCI(P<0.01).The total score of coping ability of patients after PCI was unchanged(P>0.05),compared with the one before PCI.The total score of coping ability of patients before PCI was positively correlated with optimistic(r=0.233,P<0.05),and negatively correlated with fatalistic(r=-0.357,P<0.01).The total score of coping ability of patients after PCI was negatively correlated with fatailstic and emotive(r=-0.341,P<0.01;r=-0.243,P<0.05,respectively).Conclusions: PCI could remarkablely increase the total coping level of patients with coronany heart disease(cexcept for emotive coping),but could not significantly affect the coping capacity.Positive coping styles could raise patients' coping ability,and promote their health,and vice versa.
