Objective To systematically evaluate efficacy and safety of endoscopic pneumatic dilation and endoscopic stent placement in treatment of achalasia. Methods Eligible studies comparing the pneumatic dilation and the stent placement in treatment of achalasia were identified by an electronic search of MedLine, Embase, ISI Web of Science, the Cochrane Database, China Biology Medicine and Wanfang databases from inception to December 2015. Two reviewers independently screened the literatures, extracted data, and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. Results A total of 4 randomized controlled trials including 343 patients with achalasia (176 cases in the pneumatic dilation group, 167 cases in the stent placement group) were subjected to the final analysis. The results of meta-analysis showed that the postoperative short term symptom relief rate had no significant difference between the pneumatic dilation group and the stent placement group 〔RR=1.03, 95%CI (0.95, 1.12),P=0.53〕, the postoperative 2-year symptom relief rate of the stent placement group was significantly higher than that of the pneumatic dilation group 〔RR=0.77, 95%CI (0.64, 0.92),P=0.005〕, but the complications rate of the stent placement group was significantly higher as compared with the pneumatic dilation group 〔RR=0.52, 95%CI (0.40, 0.69),P<0.000 01〕 too. Conclusions Although this meta-analysis has some shortcomings, preliminary results show that short term effects of pneumatic dilation and stent placement in treatment of achalasia are effective, long term effect of stent placement in treatment of achalasia is better as compared with pneumatic dilation, but it’s complications rate is higher. So in clinical diagnosis and treatment, effect, risk, patient’s physical condition, and demand should be considered together; during treatment, we should pay attention to adverse reactions and prepare adequately in order to reducing complications. When complications occur, we should take timely symptomatic treatment.
Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
ObjectiveTo evaluate the efficacy of staged carotid artery stenting and coronary artery bypass grafting in the treatment of coronary heart disease complicated with carotid stenosis. MethodsThe clinical data of patients with coronary heart disease and carotid stenosis treated in Fuwai Hospital from November 2019 to September 2021 were retrospectively analyzed. All patients underwent staged carotid artery stenting and coronary artery bypass grafting. The incidence and risk factors of severe complications such as myocardial infarction, cerebral infarction and death during the perioperative period and follow-up were analyzed. ResultsA total of 58 patients were enrolled, including 47 males and 11 females with an average age of 52-77 (64.2±5.6) years. No complications occurred before coronary artery bypass grafting. There was 1 myocardial infarction, 1 cerebral infarction and 1 death after the coronary artery bypass grafting. The early complication rate was 5.2%. During the follow-up of 18.3 months, 1 cerebral infarction and 2 deaths occurred, and the overall complication rate was 10.3%. According to Kaplan-Meier survival curve analysis, patients with symptomatic carotid stenosis (log-rank, P=0.037) and placement of close-cell (log-rank, P=0.030) had a higher risk of postoperative ischemic cerebrovascular event, and patients with previous cerebral infarction had a higher risk of postoperative severe complications (log-rank, P=0.044). ConclusionStaged carotid artery stenting and coronary artery bypass grafting is safe and feasible for the treatment of coronary heart disease complicated with carotid stenosis.
ObjectiveTo systematically review the long-term efficacy of coronary artery bypass grafting (CABG) versus drug-eluting stent implantation (DES-PCI) for patients with multivessel coronary artery disease. MethodsWe searched The Cochrane Library (Issue 2, 2015), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP to collect randomized controlled trials (RCTs) about CABG versus DES-PCI for patients with coronary multivessel disease from the inception to October 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of seven RCTs, involving 5 723 patients were included. The results of meta-analysis showed that: compared with the DES-PCI group, the CABG group had lower 1-year incidence of target vessel revascularization (OR=0.39, 95%CI 0.31 to 0.48, P<0.000 01), 5-year mortality (OR=0.78, 95%CI 0.65 to 0.94, P=0.008), and 5-year incidence of myocardial infarction (OR=0.46, 95%CI 0.37 to 0.58, P<0.000 01). However, 1-year, 2-year and 5-year incidences of stroke in the CABG group were significantly higher than that in the DES-PCI group (all P values <0.05). ConclusionThe available evidence suggests that CABG is superior to DES-PCI for patients with multivessel coronary artery disease in long-term effects, but CABG could increase the incidence of stroke. Due to the quantity and quality of the included studies, the above conclusions still need to be verified by more high-quality RCTs.
Objective To investigate the association between D-dimer levels within 2 hours of admission and in-hospital major adverse events (MAEs) in patients with acute type A aortic dissection (ATAAD) who underwent total arch replacement combined with frozen elephant trunk (FET) implantation. Methods This retrospective study included patients with ATAAD who underwent total arch replacement with FET implantation at Fuwai Yunnan Cardiovascular Hospital from September 2017 to December 2022. Patients were divided into two groups based on the occurrence of in-hospital MAEs: a MAEs group and a non-MAEs group (control). Perioperative data were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for in-hospital MAEs, which included in-hospital death, gastrointestinal bleeding, paraplegia, acute kidney injury, low cardiac output syndrome, stroke, respiratory failure, multiple organ dysfunction syndrome, and severe infection. The predictive value of D-dimer was evaluated using the area under the receiver operating characteristic curve (AUC). Results A total of 218 patients were included (157 males, 61 females), with a mean age of (51.54±9.79) years. There were 152 patients in the non-MAEs group and 66 in the MAEs group. The overall incidence of in-hospital MAEs was 30.3%, and the in-hospital mortality rate was 2.8% (6/218). Compared to the non-MAEs group, the MAEs group had significantly higher levels of D-dimer and lactate, as well as longer cardiopulmonary bypass time, aortic cross-clamp time, and ICU length of stay (all P<0.05). Multivariate logistic regression analysis identified D-dimer as an independent risk factor for in-hospital MAEs [OR=1.077, 95%CI (1.020, 1.137), P=0.013]. The AUC for the D-dimer level within 2 hours of admission to predict in-hospital MAEs was 0.83 [95%CI (0.736, 0.870), P<0.001]. The optimal cutoff value was 2.2 μg/mL, with a sensitivity of 84.8% and a specificity of 73.0%. Conclusion The serum D-dimer level is an independent risk factor for in-hospital MAEs in patients with ATAAD following total arch replacement with FET implantation. D-dimer levels on admission can help clinicians optimize risk stratification and perioperative management, potentially reducing the incidence of early adverse events.
ObjectiveTo analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. MethodsWe reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). ConclusionStaged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.
ObjectiveTo investigate the factors related to recurrent coronary events in patients after coronary artery stent implantation. MethodsWe retrospectively studied the patients performing coronary angiography (CAG) who were admitted to the Department of Cardiology of the Second Affiliated Hospital of Guangzhou Medical University between January 2012 and June 2013. All of the enrolled patients had received CAG in our hospital, with complete coronary angiogram and clinical data. The patients were divided into two groups according to the coronary angiogram and clinical data: coronary event group and non-coronary event group. SPSS 16.0 software was employed for statistical analysis, and multivariate analysis was performed using binary logistic regression model to analyze the risk factors. ResultsA total of 115 patients were included, of which 50 patients had recurrent coronary events. Both the serum total bilirubin and unconjugated bilirubin in patients with coronary events were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05 or P < 0.01). The serum total bilirubin at baseline and the serum total bilirubin and unconjugated bilirubin at the time of CAG reexamination were significantly lower in patients with revasculization due to the progression of coronary artery lesions compared with the patients without coronary events (P < 0.05 or P < 0.01). The serum unconjugated bilirubin in patients with in-stent restenosis were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05). The results of logistic regression analysis showed that multi-vessel coronary artery disease (two-vessel coronary artery disease: OR=10.094, 95%CI 2.498 to 40.798, P=0.001; three-vessel coronary artery disease: OR=16.047, 95%CI 4.121 to 62.481, P=0.000) and low serum unconjugated bilirubin (OR=0.873, 95%CI 0.773 to 0.987, P=0.03) were independent risk factors of recurrent coronary events. ConclusionMulti-vessel coronary artery disease and low serum unconjugated bilirubin are independent risk factors of recurrent coronary events in patients after coronary artery stent implantation.
