Effect of Cardiac Rehabilitation Therapy Combined with WeChat Platform Education on Patients with Unstable Angina Pectoris after PCI

Objective. The aim of this study is to explore the effect of cardiac rehabilitation therapy combined with WeChat platform education on patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Methods. Eighty-eight UAP patients undergoing PCI in our hospital from June 2018 to June 2021 were chosen as the study subjects and were grouped according to the intervention methods. Specifically, patients receiving routine treatment only were included as the control group (CG) and those receiving cardiac rehabilitation therapy combined with WeChat platform education based on the routine treatment were included as the study group (SG), with 44 cases in each group. The clinical efficacy was compared between the two groups after intervention. Results. Compared with CG, SG achieved notably better biochemical indexes of TC, TG, FBG, FIB, LDL-c, and HDL-c after 12 months of intervention ( <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"> <a:mi>P</a:mi> <a:mo><</a:mo> <a:mn>0.05</a:mn> </a:math> ), lower systolic pressure (SBP), and diastolic pressure (DBP) after intervention ( <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" id="M2"> <c:mi>P</c:mi> <c:mo><</c:mo> <c:mn>0.05</c:mn> </c:math> ), and higher scores of limited mobility, anginal stability, anginal frequency, subjective perception, treatment satisfaction, and total SAQ after 12 months of intervention ( <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M3"> <e:mi>P</e:mi> <e:mo><</e:mo> <e:mn>0.05</e:mn> </e:math> ). The LVEF levels of both groups increased after intervention ( <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" id="M4"> <g:mi>P</g:mi> <g:mo><</g:mo> <g:mn>0.05</g:mn> </g:math> ), and the LVEF level was higher in SG than in CG ( <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" id="M5"> <i:mi>P</i:mi> <i:mo><</i:mo> <i:mn>0.05</i:mn> </i:math> ). The incidence of adverse cardiac events such as heart failure, ventricular arrhythmia, and sudden cardiac death was slightly higher in CG than in SG within 12 months of intervention, with no statistical difference ( <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" id="M6"> <k:mi>P</k:mi> <k:mo>></k:mo> <k:mn>0.05</k:mn> </k:math> ). The UAP recurrence rate and incidence of myocardial infarction in CG were obviously higher than those in SG ( <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" id="M7"> <m:mi>P</m:mi> <m:mo><</m:mo> <m:mn>0.05</m:mn> </m:math> ). Conclusion. Cardiac rehabilitation therapy combined with WeChat platform education intervention measures for UAP patients after PCI can effectively control the biochemical indexes such as blood lipid and blood glucose, improve the cardiac function, stabilize the disease condition, lower the recurrence rate, and reduce the incidence of other cardiac adverse events.
