Aim This study aimed to explore the effect of implementing pre‐operative WeChat‐assisted health education for parents of children with restrictive ventricular septal defects to improve their quality of life. Methods A prospective randomised controlled study was conducted in a provincial hospital in China. Participants were randomly divided into the intervention group (WeChat group, n = 35) and the control group (leaflet group, n = 35). The quality of life of parents of children with restricted ventricular septal defects was studied. Results Compared with the leaflet group, the WeChat group had a significantly lower score for the pre‐operative Self‐Rating Anxiety Scale (SAS) (P < 0.05). The pre‐operative SAS score in the WeChat group was significantly lower than that at the first visit (P < 0.05). However, the SAS score in the leaflet group was similar at the time of preoperation and the first visit (P > 0.05). The pre‐operative scores of the World Health Organization Quality of Life‐BREF (WHOQOL‐BREF) scale in the physiological, psychological, social, and environmental fields and the total life quality score in the WeChat group were significantly higher than those of the leaflet group (P < 0.05). Conclusion Implementing pre‐operative WeChat‐assisted health education for parents of children with restrictive ventricular septal defects can effectively relieve their anxiety and improve their quality of life.

Objective: The purpose of this study was to explore the effects of music therapy on pain, anxiety and depression in patients after coronary artery bypass grafting. Methods: A retrospective study of 99 patients after coronary artery bypass from January 2017 to January 2019 was conducted in a cardiac center in China. According to the different interventions, all the participants were divided into 3 groups: group A: music therapy; group B: rest without music therapy; and group C: conventional treatment. The Numerical Rating Scale (NRS), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were used to measure the patient's pain, anxiety and depression before and after 30 min of the intervention. Results: There were no significant differences in the NRS, SDS and SAS scores between the three groups of patients before the intervention. After 30 min of music therapy, the NRS, SDS and SAS scores of patients in group A were significantly lower than those before music therapy, and the differences were statistically significant. However, before and after the intervention in groups B and C, the NRS, SDS and SAS scores were not statistically significant. By comparison among the three groups after 30 min of intervention, the NRS, SDS and SAS scores in patients in group A were significantly lower than those in groups B and C, and the differences were statistically significant. The scores were not significantly different between groups B and C. Conclusion: Music therapy can effectively alleviate the pain, anxiety and depression of patients after coronary artery bypass grafting.

Objective The purpose of this study was to explore the clinical effect of preoperative health education based on the WeChat platform for parents of children with simple congenital heart disease. Methods In this study, participants were randomly divided into an intervention group (WeChat group, n=40) and a control group (leaflet group, n=40) in our center. All parents were required to complete the Family Caregiver Task Inventory (FCTI) on the first visit and the Zarit Burden Interview (ZBI) and FCTI before the operation. Clinical, family and relevant data from children and parents were collected and subsequently analyzed. Results Before the operation, the FCTI score and the ZBI score in the WeChat group were significantly lower than those in the control group ( P =0.010, P =0.027, respectively). Compared to the FCTI score on the first visit, the preoperative status score was significantly lower in the WeChat group ( P =0.008). The rate of loss to follow-up and complications in the WeChat group was also significantly lower than in the control group ( P =0.003). Conclusion Preoperative health education assisted by the WeChat platform for parents of children with simple congenital heart disease can effectively improve the parents' care ability and reduce the burden of care, preoperative complications and the rate of loss to follow-up.

Objective To explore the effects of using the WeChat platform on the perioperative health education of parents of children who underwent transthoracic device closure of ventricular septal defects (VSDs). Methods Participants were divided into a WeChat group and a leaflet group. Responses to relevant questionnaires and clinical data were recorded and analyzed. Results Before the operation, the scores of the Caretaker Knowledge Questionnaire in the WeChat group were significantly higher than those in the leaflet group. The scores of PSQ-18 in the WeChat group were significantly higher than those in the leaflet group. All the children in the WeChat group were followed up 1 month after discharge, while four children in the leaflet group were lost to follow-up. The rate of attrition in the leaflet group was significantly higher than that in the WeChat group. For the postoperative complications, there was no significant difference between the two groups. Conclusion Perioperative health education for parents of children who undergo transthoracic device closure of VSDs through the WeChat platform can effectively enhance parents’ knowledge of care, improve parent satisfaction, which is an effective method to ensure convenient operation and reduce loss to follow-up.

Objective To investigate the effect of WeChat-based telehealth services on the postoperative follow-up of children who underwent congenital heart surgery during the COVID-19 epidemic. Methods This study retrospectively analyzed the clinical and family data of 108 children who underwent congenital heart surgery and underwent remote follow-up via the WeChat platform from December 2019 to March 2020 in our hospital. Results During the follow-up period, the WeChat platform was used to refer 8 children with respiratory infection symptoms to local hospitals for treatment. Two children with poor incision healing were healed after we used the WeChat platform to guide the parents in dressing the wounds on a regular basis at home. Nutritional guidance was given via the WeChat platform to 13 patients with poor growth and development. The psychological evaluation results of the parents showed that the median (range) SDS score was 43 (34-59), and 7 parents (6.5%) were classified as depressed; the median (range) SAS score was 41 (32-58), and 12 parents (11.1%) were classified as having mild anxiety. Conclusion The use of WeChat-based telehealth services was effective for the remote postoperative follow-up of children who underwent congenital cardiac surgery during the COVID-19 epidemic. Providing WeChat-based telehealth services can reduce the amount of travel required for these children and their families, which is helpful for controlling and preventing the spread of COVID-19.

Although estrogen and testosterone deficiency have often been associated with the development of cardiac diseases in postmenopausal women, the benefits of estrogen or testosterone therapy are controversial. Supplementation with high dose of estrogen or testosterone alone has been associated with many side effects, especially estrogen. This study was aimed to investigate whether supplementation of testosterone in combination with low-dose estrogen conferred stronger cardioprotective effects on ovariectomized rats subjected to ischemia/reperfusion injury. Female Sprague Dawley rats were subjected to sham operation (Sham) or bilateral ovariectomy (OVX). Two weeks after ovariectomy, OVX rats were treated with one of the following: (1) vehicle (OVX), (2) testosterone (100 μg·kg·d) (OVX+T), (3) estrogen (20 μg·kg·d) (OVX+E), (4) testosterone (100 μg·kg·d) + estrogen (20 μg·kg·d) (OVX+T+E) for 4 weeks. The hearts were mounted on the Langendorff apparatus and subjected to ischemia/reperfusion injury subsequent to the determination of hemodynamic parameters. We examined the release of lactate dehydrogenase, serum estrogen, and testosterone levels and the expression of pAkt/Akt and bax/bcl-2. Testosterone supplementation alone improved the heart function, increased p-Akt/Akt and bcl-2 expression, and decreased the release of lactate dehydrogenase. Accordingly, these effects of testosterone were more pronounced when low-dose estrogen was administered simultaneously, whereas estrogen alone at the dose of the experiment had no significant effects. These effects might be partially orchestrated by the Akt signaling pathway.

Background To investigate the effect of music therapy on early postoperative pain, anxiety, and sleep quality in patients after mechanical mitral valve replacement (MVR). Methods A total of 222 patients undergoing mechanical MVR were divided into two groups: the music group and the control group. The patients in the music group received 30 minutes of music therapy every day, whereas the patients in the control group had 30 minutes of quiet time. The visual analogue scale (VAS) was used to evaluate the degree of pain, and the Self-Rating Anxiety Scale (SAS) was used to evaluate the degree of early postoperative anxiety. We also recorded the sleep duration of the patients and used the Verran and Snyder-Halpern (VSH) Sleep Scale to evaluate the sleep quality of the patients. Results The VAS scores in the music group were significantly lower than those in the control group, and early postoperative anxiety in the music group was also significantly improved compared with that in the control group. The sleep duration in the music group was significantly greater than that in the control group. In the evaluation of sleep quality using the VSH Sleep Scale, the scores for sleep interruption, sleep length, sleep depth, degree of rest, and subjective sleep quality in the music group were significantly lower than those in the control group. Conclusions Music therapy can be an effective intervention to reduce early postoperative pain, relieve early postoperative anxiety, prolong sleep time, and improve the sleep quality of patients after mechanical MVR.
