RESUMO
Objective:To observe the construction of mobile health management model for elderly patients with coronary heart disease, and to conduct empirical research.Methods:A total of 86 elderly patients with coronary heart disease treated in Henan Provincial People's Hospital from January 2019 to January 2021 were selected.They were randomly divided into 2 groups: the control group receiving routine intervention(n=43), and the observation group receiving mobile health management mode as an add-on to routine interventions(n=43).After 3 months of intervention in control versus observation groups, angina, readmission risk factors were assessed, and status of target criteria for low-density lipoprotein cholesterol(LDL-C), resting heart rate, systolic, and diastolic blood pressure as readmission risk factors were evaluated.Before and 3 months after intervention, the self-care ability of patients was evaluated.Results:Number of angina pectoris attacks was less in observation(0.53±0.18)than in control group(0.64±0.15)( t=3.079, P=0.003).Duration of the angina pectoris was shorter in observation(2.72±0.40)min than in control group(3.06±0.55)min, ( t=3.278, P=0.002).Rate of achieving effectiveness of indicators for the risk factors of readmission was higher in observation group than in control group as following data: LDL-C(90.7% and 72.1%, χ2=4.914, P=0.027), resting heart rate(95.4% and 81.4%, χ2=4.074, P=0.044), systolic blood pressure(86.1% and 60.5%, χ2=7.182, P=0.007)and diastolic blood pressure(88.4% and 67.4%, χ2=5.472, P=0.019).The scores of self responsibility, health knowledge, self-care skills and self-concept were higher in the observation group than in the control group, with a statistical significant difference(all P<0.05). Conclusions:The construction of mobile health management model and its application in elderly patients with coronary heart disease are beneficial to improve the symptoms of angina pectoris, reduce the risk factors of readmission and improve the ability of self-care of patients.
