Effect of the WeChat Platform Health Management and Refined Continuous Nursing Model on Life Quality of Patients with Acute Myocardial Infarction after PCI

The purpose was to explore the effect of the WeChat platform health management and refined continuous nursing model on life quality of patients with acute myocardial infarction (AMI) after PCI. 100 AMI patients treated in the cardiovascular medicine of the First Affiliated Hospital of Soochow University from June 2018 to June 2019 were selected as the study subjects and randomly divided into research group and reference group, with 50 cases in each group. The reference group received routine nursing after PCI, while the research group received WeChat platform health management and continuous refined nursing. There were no significant differences in sex ratio, age, BMI, complications, education level, and residence between the two groups of patients (P > 0.05). The MPR values of patients in the two groups after intervention were significantly higher than those before intervention (P < 0.05), and the MPR value in the research group after intervention was significantly higher than that in the reference group (P < 0.05). The SF-36 scores of patients in the two groups after intervention were significantly higher than those before intervention (P < 0.001), and the SF-36 score in the research group after intervention was higher than that in the reference group (P < 0.001). The emotional, physical, and economic dimensions of patients in the research group after intervention were significantly lower than those in the reference group (P < 0.001). The HAMA and HAMD scores of patients in the research group after intervention were significantly lower than those in the reference group (P < 0.001). The nursing satisfaction score of patients in the research group was significantly higher than that in the reference group (P < 0.001). The total incidence of complications of patients in the research group after intervention was significantly lower than that in the reference group (P < 0.05). The WeChat platform health management and refined continuous nursing model can effectively improve the medication compliance of patients after PCI, improve the life quality, alleviate depression and anxiety, and reduce postoperative complications, with a definite effect, which is worthy of promotion and application.


Introduction
In recent years, with the increasing aging population in China, the prevalence of acute myocardial infarction (AMI) is increasing year by year [1,2]. AMI is the most serious type of coronary heart disease, and patients will suffer from pressing sensation of precordial pain and ischemic necrosis of cardiac muscle during the onset of the disease. erefore, taking effective first-aid measures is an important means to save the lives of patients. Clinical studies have confirmed that previous medical history, dyslipidemia, smoking, obesity, emotional agitation, and so on are all risk factors for AMI [3][4][5]. e development and application of percutaneous coronary intervention (PCI) have significantly improved the prognosis of AMI patients, and PCI has become one of the current clinical methods for the treatment of AMI.
is technique can effectively dredge the narrow or even occluded coronary artery lumen, increase myocardial blood perfusion, and effectively reduce the death risk in the acute phase of patients [6]. However, cardiovascular events may occur again in some patients after PCI, which affects the clinical treatment. e main factors are excessive anxiety or depression, low medication compliance, unhealthy lifestyles, etc.
e WeChat platform is mobile software used by modern people to obtain information and communicate instantly, with the advantages of easy operation, rich content, etc. Health management by means of the WeChat platform can timely and efficiently solve the problems raised by patients, establish a good monitoring and feedback mechanism, and improve the quality of nursing service [7][8][9]. A refined continuous nursing model can provide good nursing services for patients discharged from hospital, help patients develop healthy life habits, and strengthen guidance and supervision of medication for patients, which is conducive to establishing a good nurse-patient relationship and improving patients' nursing satisfaction [10][11][12].

Methods.
e reference group received routine nursing after PCI through carrying out clinical health education to patients, informing them of medication precautions, dietary intervention, psychological guidance, etc. After discharge, the patients were followed up by telephone every two weeks to inquire about medication and changes in their conditions, etc. e patients were required to have at least one outpatient follow-up every month, for 3 months. To further explore the effect of the WeChat platform health management and refined continuous nursing model on the life quality of AMI patients after PCI, 100 AMI patients treated in the cardiovascular medicine of the First Affiliated Hospital of Soochow University from June 2018 to June 2019 were selected as the study subjects, summarized and reported as follows.
e research group received the WeChat platform health management combined with refined continuous nursing model.
WeChat platform health management: during hospitalization, bed nurses set up health management records for patients meeting the requirements, including information of drugs to treat the disease, etc. A WeChat group for AMI health management was established, and patients were added into the Wechat group whose contacts were patients or family members (for elderly people who could not use smartphones). e medical staff in WeChat group included 2 doctors of cardiology, 1 cardiovascular specialist nurse, and 4-6 nurses to answer various questions after discharge and help patients make appointments for a return visit. e attending doctor gave video lectures in the group every 2 weeks to explain related knowledge of AMI disease. e patients needed to complete the tasks of clocking in, taking medicine, and measuring blood pressure and heart rate in the group every day. A reward system was formulated, and the patients could receive rewards at the end of 1 month if they performed well to encourage them to keep return visits. Refined continuous nursing model: (1) a refined continuous nursing team was established, including department doctors and specialist nurses. e head nurses with better nursing service and rich experience served as the team leader to conduct AMI knowledge training for other team members, with the contents of nurse-patient communication skills, refined continuous nursing knowledge and specialist knowledge, etc. Records for patients were established, including name, age, contact information, home address, and medication after discharge. (2) e family visit was conducted at least once a month, and telephone follow-up was conducted at least once a week. In the visits and follow-up, the patients were told to eat more fresh fruits and vegetables, pay attention to the intake of vitamins, carbohydrates, and other nutrients, maintain a low-salt, low-oil, and low-fat diet, quit smoking and alcohol, and carry out proper physical exercise which did not cause panic or chest tightness. e patients were also guided and supervised to take antiplatelet, hypoglycemic, and antihypertensive drugs on time. Communication with family members was strengthened, and psychological counseling to patients was conducted if necessary to alleviate adverse emotions such as depression and anxiety. (3) Reminder for continuation of medication: attention was paid to the patients' medication, and telephone or short message reminders were given to patients at 4 days before the completion of medication, for 3 months.

Observation Indexes.
Medication possession ratio (MPR) was calculated to reflect patients' medication compliance by recording the names, doses, and frequencies of drugs in the two groups. MPR � days of drug coverage/total treatment time × 100%, with a range of 0-100%. e higher the ratio was, the higher the medication compliance of the patients was.
Short-form 36 health surveys (SF-36 scoring) [13] were used to evaluate the life quality of patients in the two groups before and after intervention. ere were 36 scoring items in the scale, with a total score of 100 points. e higher the score was, the higher the life quality of the patients was.
e self-perceived burden scale (SPBS) [14], a Chineselanguage version, was used to evaluate the self-perceived burden of patients in the two groups after intervention. e scale consisted of 10 scoring items with a total score of 50 points. e higher the score was, the heavier the self-perceived burden of the patients was.
e Hamilton Anxiety Scale (HAMA) [15] and Hamilton Depression Scale (HAMD) [16] were used to evaluate the degree of anxiety and depression after intervention in the two groups of patients. e total score of each scale was 30 points, and the higher the score was, the more serious the anxiety or depression of the patients was.
e self-designed "Questionnaire for Patient Clinical Nursing Satisfaction" was used to evaluate the nursing satisfaction of patients in the two groups. e questionnaire was filled out at the last outpatient follow-up of the patients.
ere were 5 scoring items on the scale, with a total score of 100 points. e higher the score was, the higher the patients' satisfaction with the nursing was. e incidence of clinical complications after intervention was recorded and compared between the two groups.

Statistical Methods.
e experimental data were statistically analyzed and processed by SPSS21.0 software. GraphPad Prism 6 (GraphPad Software, San Diego, USA) was used to draw pictures of the data. e count data were tested by x 2 , expressed by [n (%)], and the measurement data were measured by the t-test, expressed by (x ± s). e difference was statistically significant when P < 0.05.

e total incidence of complications after intervention in the research group was significantly lower than that in the reference group (P < 0.05), as shown in Table 4.

Discussion
As a common clinical cardiovascular disease, AMI refers to acute myocardial necrosis caused by severe and lasting myocardial ischemia [17]. With the increasing improvement of the PCI technique, this technique has gradually become the first treatment method to achieve reperfusion of infarctrelated vessels and restore normal myocardial function in  Note. e abscissa represents before intervention and after intervention, and the ordinate represents SF-36 scores (points). e SF-36 scores of the research group were (54.27 ± 6.35)% and (74.26 ± 6.44)%, respectively, before and after intervention. e SF-36 scores of the reference group were (54.30 ± 6.32)% and (63.84 ± 6.36)%, respectively, before and after intervention. * indicates that there was a significant difference in SF-36 scores in the research group before and after intervention (t � 15.629, P � 0.000); * * indicates that there was a significant difference in SF-36 scores in the reference group before and after intervention (t � 7.524, P � 0.000); and * * * indicates that there was a significant difference in SF-36 scores between the two groups after intervention (t � 8.140, P � 0.000). AMI patients. Clinical studies have confirmed that PCI has a significant short-term clinical efficacy in AMI patients, but cardiovascular events are likely to occur again with the changes in patients' lifestyles after discharge. Besides, the patients have anxiety, depression, and other adverse emotions and worry about the cost of treatment, which seriously affects the disease treatment and prognosis. Routine nursing service after PCI confines the focus of nursing to patients during hospitalization, implements clinical health education for patients about to be discharged, and informs patients of basic nursing services such as medication methods and dosage, which results in a "disruption" state after patients are discharged from hospital. For patients with low knowledge of their own diseases or more negative emotions, their medication compliance after discharge is worse [18][19][20]. WeChat, as a common communication tool for young and middle-aged people, can make up for the deficiencies of clinical nursing in hospitals to some extent and break the limitation of routine nursing after PCI, which truly provides more high-quality services for patients. Chapman et al. [21] believe that WeChat, as a real-time communication tool, can help doctors timely understand the condition and psychological changes of discharged patients and take effective measures to address their situation to break the limitations of space and time and meet the nursing needs of patients after discharge. In this study, WeChat platform health management was implemented for patients after PCI, urging patients to clock in the group every day and report medication. e MPR value of patients after intervention was significantly higher than that of the reference group (P < 0.001). Nicole R. Pinelli et al. [20] pointed out in their paper that, "after the implementation of WeChat platform health management for rectal cancer patients undergoing radical resection, the MPR value of patients after intervention was (85.67 ± 3.28)%, significantly higher than that of the reference group (75.21 ± 3.32)%," indicating that WeChat platform health management can effectively improve the treatment compliance of discharged patients and accelerate physical rehabilitation. In addition, the refined continuous nursing model provides comprehensive,  Figure 3: Comparison of nursing satisfaction scores between two groups of patients (x ± s). Note. e abscissa represents the research group and reference group, respectively, and the ordinate represents the nursing satisfaction score. e nursing satisfaction score of patients was (87.68 ± 4.82) points in the research group and (72.17 ± 4.76) points in the reference group. * indicates that there was a significant difference in nursing satisfaction scores between the two groups of patients (t � 16.190, P � 0.000).

Conclusions
How to improve the medication compliance, improve the life quality, and reduce cardiovascular complications of patients after PCI has become a hot topic in the medical field [24][25][26]. e long rehabilitation process of AMI and a variety of oral drugs for a long time in the treatment result in poor treatment compliance. is study showed that the HAMA and HAMD scores of patients after refined continuous nursing were significantly lower than those of the reference group (P < 0.001), indicating that this nursing model can effectively alleviate the adverse emotions of patients after PCI and is beneficial to treatment.
However, this study also had some shortcomings. Single cases were selected, and the results of the study were easily affected by regions. Besides, the duration of continuous nursing was only 3 months, and there was a lack of longterm follow-up studies for patients after PCI. It is suggested that the selection of samples should follow the diversification principle and the postoperative nursing service time should be prolonged.
In summary, the WeChat platform health management combined with refined continuous nursing model can significantly improve the medication compliance of patients after PCI, alleviate their negative emotions, improve the life quality, and reduce their self-perceived burden, with high safety, which is worthy of application and promotion.
