RESUMO

【Objective】 To investigate the risk factors of frailty syndrome in elderly patients with acute coronary syndrome (ACS) and their impact on prognosis. 【Methods】 The elderly patients with ACS aged 65 and over, who were hospitalized in the Department of Cardiology and Geriatric Cardiology of The First Affiliated Hospital of Xi’an Jiaotong University from September 2020 to February 2021, were selected in the cross-sectional survey. The patients were divided into frailty syndrome and non-frailty syndrome groups via the Chinese revised version of Tilburg Frailty Scale. We collected the patients’ activities of daily living, nutrition, depression, sleep quality, total cholesterol, triglycerides, low-density lipoprotein, and adverse events during hospitalization and within 30 days of discharge. We then performed LOG-BINOMIAL regression to analyze the risk factors of frailty syndrome. 【Results】 A total of 250 elderly ACS patients were enrolled, and 118 patients were diagnosed with frailty syndrome with 47.2% prevalence of frailty syndrome. There was a significant difference in the average score between the frailty syndrome group and the non-frailty syndrome group (11.06±2.53 vs. 5.77±1.54, P<0.01). Multivariate regression analysis revealed that age (PR=2.01 CI: 1.81-2.22, P<0.001), hypertension (PR=1.20 CI: 1.09-1.30, P<0.001), chronic kidney disease (PR=1.16 CI:1.04-1.29, P=0.012), and NT-proBNP (PR=1.20 CI: 1.07-1.35, P=0.004) were risk factors for frailty syndrome in elderly ACS patients. The incidence of arrhythmia and pulmonary infection during hospitalization and the rate of readmission within 30 days after discharge were significantly higher in the frailty syndrome group than those in the non-frailty syndrome group (P<0.05). 【Conclusion】 There is a higher incidence of frailty syndrome in elderly patients with ACS. Older age, hypertension, chronic kidney disease and high NT-proBNP can increase the risk of frailty syndrome. In clinical practice, attention should be paid to the above factors, and reasonable intervention should be provided in time.

RESUMO

Chemotherapy-related cardiotoxicity is common and has become one of the factors that affect the prognosis of patients. Early identification and intervention of chemotherapy-related cardiotoxicity is very important. Currently, the commonly used clinical, imaging and laboratory examination methods have their own shortcomings, while PET/CT imaging has not been widely used for chemotherapy-related cardiotoxicity. This article reviews the current application and deficiencies of PET/CT imaging in animal experiments and human trials of chemotherapy-related cardiotoxicity.

RESUMO

Objective To reveal the role of serum ACE2/Ang (1-7)in the occurrence of atrial fibrillation (AF)and find new targets for the prevention and treatment of AF by analyzing the correlation between the serum concentration of ACE2/Ang (1-7 )in patients with rheumatic valvular heart disease and the occurrence of AF. Methods We collected the basic clinical information and peripheral venous blood of patients with rheumatic heart valve disease (totally 46 patients,including 24 with AF and 22 with SR).ELISA method was used to detect the serum concentration of ACE2,Ang (1-7)and AngⅡ in the serum samples.Then the differences and correlation between the two groups were analyzed.Results In the AF group ① the diameter of the left atrium was significantly greater than that in the SR group [(60.70±3.08 vs.48.15±2.16)mm,P<0.05];② the serum concentration of AngⅡ was significantly higher than that in the SR group [(45.88±2.87 vs.35.78±1.08)pg/mL, P<0.05],AngⅡ and left atrium diameter were positively correlated (Pearson test,P<0.05);③ the serum concentrations of ACE2 [(7.87±0.74 vs.11.65±0.57)U/L,P<0.05]and Ang (1-7)[(146.05±17.61 vs. 321.71±36.50)pg/mL,P<0.05]were significantly lower than those in the SR group,and negatively correlated with left atrium diameter (Pearson test,P<0.05);④ the serum concentration of Ang (1-7)was negatively correlated with AngⅡ concentration (Pearson test,P<0.05).Conclusion For patients with rheumatic valvular heart disease,ACE2/Ang (1-7 )may play a protective role in the occurrence of AF via antagonizing AngⅡ and inhibiting atrial remodeling.

RESUMO

Objective To assess the therapeutic effect and safety of radiofrequency catheter ablation of atrial fibrillation.Methods We analyzed the clinical data of 47 patients with atrial fibrillation who underwent radiofrequency catheter ablation between March 2013 and January 2008,in the First Affiliated Hospital of Xi'an Jiaotong University.In the average 32 months’follow-up,Holter monitering and echocardiography were reviewed for the left atrial diameter.Results The immediate success rate of catheter ablation for atrial fibrillation was 82.6%.The long-term success rate was 65%,the rate of paroxysmal atrial fibrillation was 69.7%,and the rate of longstanding persistent atrial fibrillation was 42.9%.After ablation,the left atrial diameter were markedly reduced compared with that before treatment [(36.3 ± 4.3 )mm vs .(38.1 ± 5.9 )mm)(P < 0.001 ).The patients with recurrent atrial fibrillation were older than those without recurrence,their left atrial diameter was bigger,and the prevalence rate of hypertension was higher (P <0.05).The average atrial fibrillation load was 14.9% after ablation compared with 46.1% before (P <0.05).Conclusion Radiofrequency catheter ablation is an effective and safe treatment of atrial fibrillation,especially for paroxysmal atrial fibrillation.The left atrial diameter was significantly decreased after radiofrequency catheter ablation compared with that before the ablation.

RESUMO

Objective To assess the effectiveness and safety of radiofrequency catheter ablation for idiopathic ventricular arrhythmia in patients with idiopathic ventricular arrhythmia after radiofrequency catheter ablation treated in the First Affiliated Hospital of Xi’an Jiaotong University based on the follow-up and retrospective analysis.Methods We retrospectively analyzed the clinical data of 63 patients with idiopathic ventricular arrhythmia who underwent radiofrequency catheter ablation during January 2008 and March 2014 in the First Affiliated Hospital of Xi’an Jiaotong University.In the follow-up,Holter moniterings were reviewed to evaluate ventricular arrhythmia and echocardiography to assess the ejection fractions and left ventricular end-diastolic diameters.Results The immediate success rate of catheter ablation for the treatment of idiopathic ventricular arrhythmia was 89.29% and the long-term success was 82.14%.The ejection fractions and left ventricular end-diastolic diameters were not obviously improved after radiofrequency ablation (P > 0.05 ). The ventricular premature contractions were significantly reduced after radiofrequency ablation (P <0.05).In postoperative care, one case was found with ruptured sinus valsalva tumor and another patient was found with the complication of hematoma in femoral artery puncture.Conclusion Radiofrequency ablation for idiopathic ventricular arrhythmia is safe and effective.
