Objective To evaluate the efficacy of statins pretreatment in patients before percutaneous coronary intervention (PCI). Methods Published literature on relevant randomized controlled trials (RCTs) were retrieved via electronic and handsearch in databases CNKI, CBM, MEDLINE and The Cochrane Library from January 1990 to May 2011. The references of these articles were also retrieved. Two reviewers independently identified articles according to the inclusion and exclusion criteria, extracted the data, assess the quality of the included studies, and then conducted meta-analysis using RevMan 5.0 software. Results A total of 10 trials involving 3 012 patients were included. The results of meta-analyses showed that: during the periprocedural period, the trial group had a lower incidence than the control group (98 of 1 514 cases, incidence 6.5%) in periprocedural myocardial infarction with a significant difference (OR=0.43, 95% CI 0.34 to 0.56, Plt;0.000 01). The composite of death, myocardial infarction, or target vessel revascularization in one month, essentially driven by periprocedural myocardial infarction, was reported 6.8% in the trial group and 15.1% in the control group (OR=0.41, 95% CI 0.32 to 0.53, Plt;0.000 01). Conclusion Current evidence supports the effectiveness of statin pretreatment used to reducing the rate of periprocedural myocardial infarction in patients before receiving PCI.
Objective To systematically review the impact of cardiac shock waves on coronary artery disease. Methods The PubMed, Cochrane Library, Wed of Science, EMbase, ClinicalTrials.gov, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect randomized controlled trials and cohort studies related to the treatment of coronary artery disease with cardiac shock waves from inception to August 2022. After two evaluators independently screened the literature, extracted data, and evaluated the risk of bias of the included studies, a meta-analysis was conducted by using RevMan 5.4.1 and Stata 15.0 software. Results A total of 11 studies with 519 patients were included. The meta-analysis results revealed that compared with the control group, cardiac shock wave therapy could reduce hospitalization rates (RR=0.38, 95%CI 0.25 to 0.57, P<0.01), increase exercise time (SMD=0.93, 95%CI 0.17 to 1.70, P=0.02), and improve the Canadian Cardiovascular Society (CCS) angina grading (MD=−0.62, 95%CI −0.73 to −0.51, P<0.01), the New York Heart Association (NYHA) cardiac function grading (MD=−0.60, 95%CI −0.85 to −0.35, P<0.01), left ventricular ejection fraction (MD=4.81,95%CI 3.17 to 6.46, P<0.01), total score of the Seattle angina questionnaire (SAQ) (MD=10.87, 95%CI 4.63 to 17.12, P<0.01), and 6-min walking test (MD=85.06, 95%CI 31.02 to 139.09, P<0.01). Conclusion Cardiac shock wave therapy can improve cardiac function as well as the prognosis and exercise ability. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Abstract:Objective To investigate clinical characteristics of patients with aortic valve disease and coronary artery disease （CAD）， and improve the pertinence of clinical management. Methods Clinical data of 78 patients who were older than 50 years and underwent isolated aortic valve replacement （AVR） in General Hospital of Shenyang Command from January to October 2010. All the patients were divided into two groups according to whether they had CAD：20 patients with CAD in the CAD group， including 19 males and 1 female with their average age of 64.6±8.3 years， and 58 patients without CAD in the control group， including 28 males and 30 females with their average age of 58.7±6.2 years. Clinical characteristics of AVR patients with CAD were analyzed by one-way analysis of variance and multiple factor analysis. Results One-way analysis showed that the incidence of old age （P=0.000）， male patients （P=0.004）， diabetes （P=0.004）， aortic regurgitation （P=0.034）， valvular lesion （P=0.028）， and postoperative mechanical ventilation time （P=0.008）of CAD group patients were significantly higher or longer than those of control group patients. Multiple factor analysis showed that independent clinical characteristics of AVR patients with CAD included male patients， old age， prolonged postoperative mechanical ventilation time， significantly decreased pulmonary arterial systolic pressure （PASP） at 6th postoperative month， and significant preoperative right ventricular diastolic dysfunction. Conclusion The screening age for possible CAD should be reasonably lowered if male patients with aortic valve disease have concomitant preoperative right ventricular diastolic dysfunction and/or tricuspid aortic valve degeneration. Patients undergoing isolated AVR need to take medications to reverse left ventricular remodeling for a long time to avoid severe arrhythmia.
Objective To compare the clinical effects of coronary artery bypass grafting (CABG) via the left anterior small thoracotomy (LAST) versus lower-end sternal splitting (LESS) approach in the treatment of coronary heart disease. Methods The patients who underwent LAST CABG in Tianjin Chest Hospital from October 2015 to December 2020 were allocated to an observation group (LAST group), and the patients who underwent LESS CABG at the same period were allocated to a LESS group. Propensity score matching method was applied with a ratio of 1∶1. The baseline data, perioperative data and grafts data were compared between the two groups after matching. Results Before matching, there were 110 patients in the LAST group, and 206 patients in the LESS group. After matching, there were 110 patients in each group. In the LAST group, there were 83 males and 27 females with an average age of 60.6±8.3 years. In the LESS group, there were 80 males and 30 females with an average age of 61.0±9.6 years. There was no statistical difference in baseline data between the two groups after matching (P>0.05). The hospital stay time (t=2.255, P=0.025) and ventilator using time (t=−2.229, P=0.027) in the LAST group were significantly shorter than those in the LESS group. There were no statistical differences between the two groups in the postoperative hospital stay time, ICU stay time, postoperative left ventricular ejection fraction, postoperative left ventricular end-diastolic diameter, average number of grafts, secondary intubation, secondary thoracotomy, postoperative wound infection, sternal complications, postoperative atrial fibrillation, postoperative pulmonary infection or main adverse cardiovascular and cerebrovascular events (P>0.05). There was no statistical difference in the distribution of target vessels in the anterior descending branch, diagonal branch or posterior descending branch between the two groups (P>0.05). The grafts of the LAST group were significantly more than those of the LESS group in the area of obtuse marginal branch and posterior ventricular branch, and the grafts of the LESS group were significantly more than those of the LAST group in the area of right coronary artery (P<0.05). Postoperative computerized tomography angiography indicated that 1 patient in the LAST group had obtuse marginal branch vein bridge vessel occlusion, and the bridge vessels in the other patients were unobstructed. Conclusion Minimally invasive CABG via both LAST and LESS approaches is safe and effective. LAST approach can achieve complete revascularization for multi-vessel lesions, and it is safe and reliable, with the advantages of less trauma and aesthetic appearance. However, it requires a certain learning curve of surgical techniques and certain surgical indications.
ObjectiveTo systematically review whether or not obstructive sleep apnea hypopnea syndrome (OSAHS) increases the incidence of atrial fibrillation in coronary artery disease patients.MethodsPubMed, EMbase, The Cochrane Library, SinoMed, CNKI, VIP and WanFang Data databases were searched for studies on the relationship between OSAHS and the incidence of atrial fibrillation in coronary artery disease patients from inception to July 2nd, 2018. Two reviewers independently screened literatures, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.ResultsIn total, 11 cohort studies were included, involving 709 in exposed group and 975 in non-exposed group. The results of meta-analysis indicated that OSAHS was associated with the incidence of atrial fibrillation in coronary artery disease patients (RR=2.01, 95%CI 1.72 to 2.36, P<0.000 01). The subgroup analysis showed that OSAHS of PSG diagnosis increased the risk of the incidence of atrial fibrillation in coronary artery disease patients (RR=2.40, 95%CI 1.84 to 3.12, P<0.000 01); moderate and severe OSAHS of PSG diagnosis had higher risk of the incidence of atrial fibrillation in coronary artery disease patients (RR=3.73, 95%CI 2.51 to 5.53, P<0.000 01); high risk OSAHS of Berlin questionnaire assessment increased the incidence of atrial fibrillation in CAD patients (RR=1.56, 95%CI 1.27 to 1.92, P<0.000 1).ConclusionThe current evidence indicates that OSAHS is associated with an increased risk of atrial fibrillation in coronary artery disease patients. Due to the limitation of quality and quantity of the included studies, more large-scale and fine quality research are needed to warrant the accuracy of conclusion above.
ObjectiveTo explore the prevalence of depression and anxiety of chronic obstructive pulmonary disease complicated coronary artery disease before and after percutaneous intracoronary arterial stenting. MethodsA total of 114 chronic obstructive pulmonary disease complicated coronary artery disease patients were enrolled in this study and were measured with the Hospital Anxiety and Depression Scale before and after percutaneous intracoronary arterial stenting. ResultsA total of 71 patients (62.3%) had depression symptom and 68 patients (59.6%) had anxiety symptom before percutaneous intracoronary arterial stenting. There were 46 patients (40.4%) had significant depression symptom and 40 patients (35.1%) had significant anxiety symptom before percutaneous intracoronary arterial stenting. A total of 85 patients (74.6%) had depression symptom and 83 patients (72.8%) had anxiety symptom after percutaneous intracoronary arterial stenting. There were 60 patients (52.6%) had significant depression symptom and 48 patients (42.1%) had significant anxiety symptom after percutaneous intracoronary arterial stenting. There was significant difference in prevalence rate of depression and anxiety before and after percutaneous intracoronary arterial stenting (P < 0.05). ConclusionsThe patients with chronic obstructive pulmonary disease complicated coronary artery disease show higher prevalence of depression and anxiety. The prevalence of depression and anxiety increases significantly after percutaneous intracoronary arterial stenting.
ObjectivesTo assess the accuracy of different types and magnetic field intensity of cardiac magnetic resonance for coronary artery disease.MethodsPubMed, The Cochrane Library, EMbase, WanFang Data, CNKI and CBM databases were searched to collect the studies on different types and magnetic field intensity of cardiac magnetic resonance for coronary artery disease from inception to May 15th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, data were synthesized by using MetaDisc 1.4, RevMan 5.3 and Stata 12.0 softwares. The pooled sensitivity (Sen), pooled specificity (Spe), pooled positive likelihood ratio (+LR), pooled negative likelihood ratio (–LR), pooled diagnostic odds ratio (DOR) and the area under curve (AUC) of the summary receiver-operating characteristic curve (SROC) were used to assess the diagnostic value of different types and magnetic field intensity of cardiac magnetic resonance.ResultsTwenty diagnostic studies were included, which involved 1 357 patients. The results of meta-analysis showed that (1) based on patient: compared with the gold standard, the pooled Sen, Spe, +LR, –LR, DOR and the AUC of SROC, pre-test probability, post-test probability were (0.87, 95%CI 0.82 to 0.90), (0.88, 95%CI 0.82 to 0.92), (7.33, 95%CI 4.74 to 11.32), (0.15, 95%CI 0.11 to 0.20), (49.53, 95%CI 27.46 to 89.36), (0.93, 95%CI 0.91 to 0.95), 20.00% and 65.00%, respectively. (2) Based on blood vessels: the pooled Sen, Spe, +LR, –LR, DOR and the AUC of SROC, pre-test probability, post-test probability were (0.81, 95%CI 0.76 to 0.85), (0.87, 95%CI 0.81 to 0.91), (6.37, 95%CI 4.37 to 9.30), (0.22, 95%CI 0.17 to 0.27), (29.58, 95%CI 18.53 to 47.22), (0.89, 95%CI 0.86 to 0.92), 20.00% and 61.00%, respectively. (3) Subgroup analysis showed that there was no difference in AUROC of different types of cardiac magnetic resonance, but significant difference was found in AUROC of 1.5T and 3.0T magnetic field intensity.ConclusionsCurrent evidence shows that, compared with gold standard, cardiac magnetic resonance can be regarded as an effective and feasible method for preoperative staging of breast cancer.
Objective?To explore the glucometabolic state of angiographically documented inpatients with coronary artery disease (CAD) but without diagnosed diabetes mellitus (DM). Methods?The study recruited 449 patients, who were performed a coronary angiography as well as an oral glucose tolerance test (OGTT) when admitted in the cardiovascular medical ward in our hospital from January 2007 to May 2009. According to the results of coronary angiography, the patients were divided into a coronary artery disease (CAD) group and a non-coronary artery disease (non-CAD) group, and abnormal glucose metabolism (AGM) status was compared between the two groups. Results?The random plasma glucose (RPG) and fasting plasma glucose (FPG) had no significant differences (P values were 0.249 and 0.444, respectively) in the two groups, while the OGTT 2-hour plasma glucose (2hPG) was much higher in the CAD group, with a significant difference (Plt;0.001) compared with the non-CAD group. The CAD group had a prevalence of AGM up to 74.0%, of which 32.1% were newly diagnosed DM patients, and 39.0% were impaired glucose tolerance (IGT) patients, much higher than that in the non-CAD group, respectively, there being a significant difference (P=0.006). Logistic regression analyses revealed that the risk of IGT and newly diagnosed DM was 1.6 times (OR=1.603, 95% CI 1.023 to 2.512, P=0.04) and 2.3 times (OR=2.292, 95% CI 1.391 to 3.777, P=0.001) as much as that in non-CAD patients, respectively; when adjusted for the factors such as hypertension, dyslipidemia, BMI, hs-CRP, and other factors, CAD patients still had a higher risk of newly diagnosed DM (OR=1.852, 95%CI 1.064 to 3.223, P=0.029), compared with the non-CAD patients. Conclusion?AGM is common in the admitted patients with CAD but undiagnosed diabetes, most of whom need an OGTT to be diagnosed timely and accurately. OGTT should be considered to be a routine inspection item to diagnose AGM in the inpatients with CAD; if possible, all hospitalized patients with cardiovascular disease should be performed an OGTT routinely.
ObjectiveTo explore the relationship between myocardial viability in patients with coronary artery disease who underwent elective coronary artery bypass grafting (CABG) and early application of intra-aortic balloon pump (IABP) after coronary revascularization, and to provide relevant clinical reference for the pre-implantation of 16G single-lumen catheter in the femoral artery of high-risk patients to facilitate the addition of IABP after operation.MethodsThis retrospective study included 521 patients (414 males and 107 females, aged 62.50±8.82 years) who underwent positron emission tomography (PET)-computed tomography (CT) perfusion-metabolism imaging prior to CABG surgery in our institution from December 2015 to August 2020. The myocardial viability information and left ventricular functional parameters were measured, including the proportion of non-viable myocardium (perfusion-metabolic imaging match), hibernating myocardium (perfusion-metabolic imaging mismatch) and dysfunctional myocardium (non-viable+viable myocardium), left ventricular ejection fraction, left ventricular end-diastolic volume and left ventricular end-systolic volume (LVESV). The patients were divided into an IABP group and a non-IABP group according to whether they received IABP treatment after revascularization. The clinical data were reviewed and compared to explore significant impact factors between the two groups. And the multivariate logistic regression analysis was performed to investigate the correlation between preoperative myocardial viability and early use of IABP after CABG.ResultsIn multivariate logistic regression analysis, the amount of non-viable, dysfunctional myocardium and LVESV value were identified as the independent predictors for the probability of IABP use in the initial postoperative period. Receiver operating characteristic analysis showed that 9.5% non-viable myocardium, 19.5% dysfunctional myocardium, and LVESV of 114.5 mL were the optimal cutoff for predicting early IABP implantation during CABG.ConclusionThe myocardial survival status displayed by preoperative PET-CT myocardial perfusion-metabolism imaging can predict the possibility of applying IABP in CABG perioperative period. In addition to routine pre-anesthesia assessment, anesthesiologists can conduct risk stratification assessment for patients with CABG according to the results of preoperative myocardial viability imaging, which is of great significance to ensure the perioperative safety of high-risk patients with CABG.
Objective To investigate the relationship between diabetic retinopathy (DR) and coronary atherosclerosis (CAS) in type 2 diabetes patients and other risk factors of DR. Methods A total of 118 patients of type 2 diabetes with DR (DR group), 120 patients of type 2 diabetes without DR matched in age and sex (non-DR group), and 86 normal controls (control group) were enrolled in this study. The body mass index (BMI), blood pressure (BP), fasting blood-glucose (FPG), glycosylated haemoglobin (HbA1C), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterin (LDL-C), creatinine, estimate glomerular filtration rate (eGFR) and urinary albumin excretion rate(UAER) in all the subjects were measured. Meanwhile, the incidence of CAS in the three groups was detected by 64slice multidetector computed tomography angiography (MDCTA). Assume concurrent DR as dependent variable, clinical indicators and laboratory parameters as independent variable, the risk factors were determined by Logistic regression analysis. In addition, CAS as dependent variable, DR as fixed factor, analysis of covariance was used to investigate the relationship between CAS and DR. Results The incidence of CAS in DR group was higher than that in nonDR group and control group, the differences were statistically significant (chi;2=26.9,35.5;P＜0.05). The results of Logistic regression analysis showed that systolic BP, BMI, CAS, myocardial infarction and UAER were key risk factors for DR ［odds ratio (OR)=1.02, 0.89, 4.50, 3.89, 1.34;P＜0.05］. There was a negative relationship between BMI and DR. The results of analysis of covariance showed that there was significant correlation between CAS and DR (OR=5.31, 95% confidence interval=2.62-10.60; P＜0.05). Conclusion CAS is independently associated with DR in type 2 diabetes patients. In addition, the other risk factors for DR include systolic BP, BMI, myocardial infarction and UAER.
