Abstract: Objective: To evaluate the effect of mhealth Apps (Tongxin Assist) +PCI Group on continuing care for CHD patients after Percutaneous Coronary Intervention (PCI) operation. Methods: We divided 60 CHD patients who had PCI operations from January to March 2015 into two groups evenly. The patients in both groups received regular discharge education and telephone visits. The patients in the treatment group received further continuing care via mhealth Apps (Tongxin Assist) +PCI Group for three months. We compared the two groups carefully at patients' knowledge of disease, level of anxiety and depression, and medicine compliance at the time of discharge as well as three months after discharge respectively. Results:After three months' intervention, the patients' knowledge of their disease and medicine compliance in the treatment group were statistically higher than those in the control group (P<0.05); the patients' level of anxiety (SAS) and depression (SDS) in the treatment group were significantly lower than those in the control group (P<0.05). Conclusion: The mhealth Apps (Tongxin Assist) +PCI group could be very effective for the continuing care for CHD patients after PCI operations.
