AIM: To study the effect of cognitive education on the rehabilitation of mental status and physical symptom in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: totally 112 patients, who had successful PCI, were selected from 186 CHD inpatients, who were hospitalized in the Cardiological Department of Second Affiliated Hospital of Xinxiang Medical College and Xinxiang Second People's Hospital and treated with PCI from January 2000 to December 2003. The patients were randomly divided into cognitive education group (n = 56) and control group (n = 56). All the patients received regular medical nursing, besides systematic cognitive education was given to those in the cognitive education group. The complication and adverse effects were observed during and after PCI. All the patients were evaluated with the self-rating depressive scale (SDS) and self-rating anxiety scale (SAS) at admission and after PCI respectively. RESULTS: The occurrences of too high or too low blood pressure and hypoglycemia during PCI, difficulty of urination and aching pain in waist and back were less in the cognitive education group that in the control group (Chi2 = 4.94 to 19.05, p < 0.05 to 0.01). The incidence rate of anxiety after PCI in the cognitive education group (14%) was significantly lower than that in the control group (39%) (Chi2 = 4.624, p < 0.05), while the incidence rate of depression (18%) was insignificantly lower than that in the control group (32%) (p > 0.05). The scores of SDS and SAS in the cognitive education group were markedly lower than those in the control group (t = 6.124, 7.028, p < 0.01), while the rate of score reduction was remarkably higher than that in the control group (t = 24.651, 22.081, p < 0.01). CONCLUSION: Systemic cognitive education can promote the physical and psychological rehabilitation of CHD patients after PCI.
