Methods: Data of 124 patients who underwent CABG in our hospital from May 2020, to May 2022, were collected. In accordance with the presence or absence of mindfulness meditation, the patients were divided into control group (n = 64, conventional cardiac rehabilitation) and observation group (n = 60, conventional cardiac rehabilitation + mindfulness meditation). The Hamilton Anxiety Scale (HAMA), General Self-Efficacy Scale (GSES), quality of life, and postoperative complications were compared between the two groups. Results: No significant difference was observed in the HAMA, GSES, and quality-of-life scores between the two groups after operation (p > 0.05). After the intervention, the HAMA score of the observation group was lower than that of the control group (p < 0.05), and the GSES and quality of life scores of the observation group were higher than those of the control group (p < 0.05). The total incidence of postoperative complications in the observation group (5.00%) was lower than that in the control group (7.81%), without significant difference (p > 0.05). Conclusions: The use of mindfulness meditation for patients undergoing CABG is beneficial to relieve anxiety and improve their self-efficacy and quality of life, hence worthy of adoption.","PeriodicalId":503802,"journal":{"name":"The Heart Surgery Forum","volume":"63 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141349314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A case–control study was conducted to select patients undergoing PCI in our hospital from June 2020 to June 2022. Patients were divided into the occurrence group and the non-occurrence group according to whether MACEs occurred during the 12-month follow-up after surgery. Enzyme-linked immunosorbent assay was used to detect the expression levels of serum apelin and CD40L in the two groups, and the correlation between the expression of apelin and CD40L and prognosis was analyzed. Logistic regression analysis was performed on the indicators with differences to analyze the influencing factors of the prognosis of PCI. Results: Compared with the non-occurrence group, the occurrence group had a significantly lower level of apelin and a significantly higher level of CD40L (p < 0.001). Apelin was negatively correlated with the occurrence of MACEs after PCI (r = –0.583, p < 0.001), and CD40L was positively correlated with the occurrence of MACEs after PCI (r = 0.569, p < 0.001). Logistic regression analysis showed that apelin was a protective factor for MACEs after PCI (odds ratio (OR) = 0.248, p < 0.001); CD40L, age, hypertension, and the number of diseased vessels were risk factors for MACEs after PCI (OR = 8.684, 0.018, 0.003, 0.020, p < 0.05). The area under curve (AUC) of apelin combined with CD40L was large, and the predictive value was higher than that of apelin and CD40L alone (AUC values were 0.956, 0.857, 0.905, p < 0.001; p < 0.001; p < 0.001). Conclusions: This study showed that the levels of apelin and CD40L were correlated with MACEs after PCI. Clinicians should pay close attention to the levels of apelin and CD40L in patients after PCI and be alert to the occurrence of MACEs.","PeriodicalId":503802,"journal":{"name":"The Heart Surgery Forum","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141346659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PAA is often associated with other cardiac and congenital heart diseases, such as atrial septal defect (ASD). We report a case of a patient with ASD and a giant dissecting PAA who underwent surgical repair to prevent potentially fatal outcome and discuss the probable etiologies of this case. We present a rare case of a 50-year-old woman with a secundum ASD and severe pulmonary arterial hypertension (PAH) who developed a giant PAA of 114 mm with dissection. The PAA caused extrinsic compression of the left main coronary artery (LMCA), which was misdiagnosed as coronary artery disease (CAD) at local hospital. Right heart catheterization revealed PAH of 73 mmHg and she was referred to our center for further treatment. After 4 months of lowering PAH treatment, she underwent successful surgical repair of the PAA to release the compression of LMCA, as well as mechanical valve replacement, fenestrated ASD closure and tricuspid valvuloplasty. She had an uneventful recovery and showed significant improvement in pulmonary hemodynamics and clinical symptoms at one-year follow-up. PAA with dissection is a rare complication of ASD and PAH that can potentially be fatal. Patients with large or symptomatic PAA and PAD may require early surgical intervention, particularly if they experience compression of nearby structures or are at risk of rupture. It is crucial to promptly refer and consult with specialists and ensure optimal preoperative hemodynamic management to enhance patient outcomes.","PeriodicalId":503802,"journal":{"name":"The Heart Surgery Forum","volume":"2 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compare the prognostic outcomes of the different treatment modalities. Methods: Computerized searches of Embase, PubMed, and the Cochrane Library databases were performed. Randomized controlled trials (RCTs) and observational studies were searched to compare prognoses following transcatheter interventions, surgery, and optimal pharmacological treatment for FMR, all with a construction timeframe of 21 October 2023. The primary endpoint event was all-cause mortality. The secondary endpoint events were heart failure readmission rate, mitral regurgitation (MR) ≤2+ improvement rate, New York Heart Association (NYHA) improvement rate (improvement to I–II), and degree of left ventricular ejection fraction (LVEF) improvement. Results: Twenty-six (26) papers were included, comprising 10 RCTs and 16 observational studies involving 5443 patients. A network meta-analysis showed no significant difference in prognosis for all-cause mortality among transcatheter interventions, surgical procedures, and optimal pharmacological treatments. For heart failure readmission rates, mitral valve surgery was superior to MitraClip (odds ratio (OR) = 11.82; 95% confidence interval (CI): 1.67, 90.13). For NYHA (improvement to I–II) improvement rates, the results showed no significant differences for the various mitral interventions. For MR ≤2+ improvement rates, the MitraClip (OR = 3.07; 95% CI: 2.42, 3.76), MitraClip+Guideline-directed medical therapy (GDMT) (OR = 2.93; 95% CI: 2.38, 3.52), mitral valve surgery (OR = 3.01; 95% CI: 2.24, 3.8), and annuloplasty (OR = 4.31; 95% CI: 3.12, 5.58) were superior to GDMT, and mitral valve surgery (OR = 0.07; 95% CI: –0.45, 0.62) was superior to MitraClip+GDMT. For the degree of improvement in LVEF, Carillon+GDMT (mean difference (MD) = –0.97; 95% CI: –1.72, –0.22) was superior to GDMT, mitral valve surgery was superior to Carillon+GDMT (MD = 4.67; 95% CI: 0.92, 8.39); MitraClip+GDMT (MD = 4.01; 95% CI: 1.28, 6.66), GDMT (MD = 3.71; 95% CI: 0.04, 7.35), and annuloplasty were superior to mitral valve surgery (MD = –6.42; 95% CI: –11.96, –0.78). Conclusion: There were no significant differences among the three treatment modalities of transcatheter intervention, surgery, and optimal drug therapy in improving all-cause mortality hard endpoint events, and no significant differences were seen in the rates of heart failure readmission and NYHA improvement (improvement to I–II).

In this review manuscript, the effect of extracorporeal membrane oxygenation (ECMO) support on complex high-risk elective PCI was critically evaluated through an analysis of relevant clinical studies. The objective is to elucidate the role of ECMO in optimizing procedural success, mitigating complications, and improving long-term patient outcomes in this high-stake domain of interventional cardiology. Methods: A comprehensive search strategy identified seven publications encompassing single-center prospective, retrospective, and case report designs, collectively involving 91 patients undergoing high-risk elective PCI with ECMO support. Results: The results from these studies demonstrated the potential of ECMO support to facilitate successful high-risk elective PCI with favorable procedural outcomes, highlighting the importance of careful patient selection and proactive management of potential complications to further optimize the use of ECMO in this clinical setting. The refinement of patient selection criteria, optimization of procedural techniques, and assessment of long-term clinical outcomes following ECMO-assisted high-risk PCI procedures represent crucial avenues for future research. Conclusions: Overall, the reviewed evidence supports the notion that ECMO represents a valuable tool for providing hemodynamic support during high-risk PCI procedures, particularly in patients deemed at very high risk for surgical revascularization.","PeriodicalId":503802,"journal":{"name":"The Heart Surgery Forum","volume":"109 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141115991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: From March 2022, to March 2023, 97 patients with CAF admitted to the Department of Cardiology of our hospital (study group) and 100 normal people who received health examination (control group) were subjected to echocardiogram and electrocardiogram to record relevant parameters for correlation analysis. Results: Significant differences were found in the electrocardiogram indices and right heart function parameters between the two groups. The study group had significantly higher heart rate, QTc interval, QT interval and T wave time than the control group (p < 0.05). The study group showed significantly higher right ventricular end-diastolic volume (RVEDV) and right ventricular end-systolic volume (RVESV), and lower right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF) than the control group (p < 0.05). Pearson correlation analysis showed that QTc interval, QT interval, and T wave time were positively correlated with RVESV (p < 0.05); QTc interval, QT interval, and T wave time were negatively correlated with RVSV (p < 0.05); and QTc interval was negatively correlated with RVEF (p < 0.05).

Therefore, the purpose of this study was to investigate the effects of early rehabilitation exercise on lower limb function and mental health after coronary artery bypass grafting. Methods: Eighty patients who underwent CABG were randomly divided into a routine exercise group and an early rehabilitation exercise group. The degree of lower limb swelling, the amount of incision complications, the first time the patient got out of bed after the operation, the length of postoperative hospital stay, activity tolerance and postoperative psychological state were compared between the two groups. Results: The incidence of postoperative lower extremity oedema was 30% in the early rehabilitative exercise group as compared to 52.5% in the routine exercise group. Between the two groups, there was a statistically significant difference (p < 0.05) in the incidence of postoperative lower limb edema as well as the amount of swelling in the thighs and ankles on postoperative days 1, 3, and 5. In the routine exercise group, the first time the patients got out of bed was 3.45 ± 1.09 days, and the length of postoperative hospitalization was 12.75 ± 5.06 days. In the early rehabilitation exercise group, the first time the patients got out of bed was 1.93 ± 0.57 days, and the length of postoperative hospitalization was 9.50 ± 2.92 days. There were statistically significant differences in these two indices between the two groups (p < 0.05). The activity tolerance of patients in the routine exercise group was 46.10 ± 19.09 min at 2 months after surgery and 69.88 ± 19.05 min at 3 months after surgery. The activity tolerance of patients in the early rehabilitation exercise group was 56.40 ± 17.42 min at 2 months after surgery and 105 ± 23.04 min at 3 months after surgery, and there was a significant difference in activity tolerance between the two groups at these time points following surgery (p < 0.05).
