ObjectiveTo investigate the impact of graft type on perioperative outcomes and long-term prognosis in patients undergoing surgical repair of post-myocardial infarction ventricular septal rupture (VSR) with concomitant coronary artery bypass grafting (CABG). MethodsA retrospective analysis was conducted on clinical data from patients who underwent VSR repair and simultaneous CABG at Fuwai Hospital between 2005 and 2022. Patients were divided into an arterial graft group and a saphenous vein graft (SVG)-only group based on the type of bypass grafts used. Clinical outcomes were compared between the two groups. ResultsA total of 92 patients were included, comprising 56 males and 36 females, with a mean age of (62.4±7.9) years. The arterial graft group consisted of 60 patients, and the SVG-only group consisted of 32 patients. There were no statistical differences between the two groups in baseline characteristics, time interval from myocardial infarction to surgery, or culprit vessel distribution (P>0.05). A higher proportion of patients in the SVG-only group received preoperative intra-aortic balloon pump (IABP) support (56.3% vs. 35.0%, P=0.049). However, cardiopulmonary bypass time, aortic cross-clamp time, and early mortality rates were similar between the two groups (P>0.05). Follow-up data revealed no statistically significant differences in cumulative 10-year survival (82.8% vs. 80.0%, P=0.940) or freedom from major adverse cardiovascular and cerebrovascular events (MACCE) (49.6% vs. 58.6%, P=0.491) between the SVG-only and arterial graft groups. Furthermore, graft type did not significantly affect long-term mortality in patients with a culprit vessel in the left anterior descending artery or those with multivessel disease. ConclusionIn patients undergoing delayed repair of VSR with concomitant CABG, the use of arterial or saphenous vein grafts did not significantly impact perioperative outcomes or long-term prognosis. Future research should further explore the benefits of different revascularization strategies to optimize treatment for this population.
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.
ObjectiveTo summarize the effectiveness and safety of antiplatelet combined with anticoagulant therapy for peripheral arterial disease (PAD). MethodUsing the search strategy developed by Cochrane Collaborative Network, the relevant literature from domestic and foreign databases as of November 1, 2023 was searched and a meta-analysis of outcome indicators was conducted using Stata 14.0 software and Review Manager 5.4.1 software provided by Cochrane Collaboration Network. ResultsA total of 15 eligible literature and 15 383 patients were included, including 7 692 in the antiplatelet combined with anticoagulant therapy group (study group) and 7 691 in the control group (only antiplatelet drug therapy). The meta-analysis results showed that: ① Symptoms: The ankle brachial index [mean difference (MD) and 95% confidence interval (95%CI)=0.04(0.02, 0.06)] and the minimum lumen diameter [MD (95%CI)=0.48(0.40, 0.55)] of the study group were greater than those of the control group; The plasma D-2 dimer level of the study group was lower than that of the control group [MD (95%CI)=–0.55(–0.57, –0.52)], and the probability of the limb ischemia risk of the study group was lower than that of the control group [risk ratio (RR) and 95%CI=0.67(0.56, 0.80)]. ② Vascular patency: The probability of the vascular patency of the study group was higher than that of the control group [RR (95%CI)=1.13(1.08, 1.17)]; The subgroup analysis results: the vascular patency rate of the two antiplatelet drugs combined with anticoagulation therapy was highest among the different treatment regimens [effect size (ES) and 95%CI=0.90(0.86, 0.94)], which of the other measures in descending order was only one antiplatelet drug combined with anticoagulation therapy [ES(95%CI)=0.82(0.76, 0.89)], two antiplatelet drugs therapy [ES(95%CI)=0.79(0.72, 0.85)], and only one antiplatelet drug therapy [ES(95%CI)=0.71(0.54, 0.87)]; The probability of the vascular patency using vitamin K antagonists in the study group was higher than that in the control group [RR(95%CI)=1.15(1.10, 1.20)], which had no statistical difference using Ⅹa inhibitor between the study group and the control group [RR(95%CI)=1.04 (0.95, 1.15)]. ③ Bleeding risk: The risk of bleeding of the study group was higher than that of the control group [RR(95%CI)=1.55(1.27, 1.89)]; The subgroup analysis results: The bleeding rate of the only one antiplatelet drug therapy among the different intervention measures was the lowest [ES(95%CI)=0.02(0.01, 0.02)], which of the other measures in ascending order was only one antiplatelet drug combined with anticoagulant therapy [ES(95%CI)=0.04(0.03, 0.06)], two antiplatelet drugs therapy [ES(95%CI)= 0.08(0.06, 0.10)], and two antiplatelet drugs combined with anticoagulant [ES(95%CI)=0.12(0.06, 0.18)]; The probabilities of the bleeding occurring using the vitamin K antagonists and Ⅹa inhibitor in the study group were higher than those in the control group [RR(95%CI)=1.76(1.28, 2.42); RR(95%CI)=1.44(1.12, 1.84)]. ConclusionsFrom the results of this meta-analysis, it can be seen that the combination of antiplatelet and anticoagulant therapy can effectively improve symptoms of patients with PAD, increase vascular patency rate, but it has a certain risk of bleeding. The combination of only one antiplatelet drug combined with anticoagulant therapy might achieve an optimum clinical effect and lower bleeding risk.
Objective To evaluate the importance of "one-stop" hybrid operating room in the individualized treatment of aortic pathology. Method We retrospectively analyzed the clinical data of 247 patients of aortic pathology who were operated in the hybrid operating room in our hospital from January 2013 through December 2014. There were 193 males and 54 females at age of 24-83(54±12) years. Results Thoracic or abdominal endovascular aortic repair (TEVAR/EVAR) was applied in 132 patients, including 122 simple patients and 10 complexes. Fenestrated TEVAR was applied in 61 patients. Hybrid operation was done in 54 patients. Perioperative death occurred in 9 patients (3.6%). Perioperative complication rate was 11.7% (29/247) . The patients were followed up for one year. During follow-up, five patients were dead. The one-year survival rate was 98.0% (242/247) . Conclusions "One-stop" individualized treatment of aortic pathology shows its advantage, yet long-term result still needs to be followed up.
Objective To investigate the impact of peripheral artery disease (PAD) on the short-term prognosis after coronary artery bypass grafting (CABG) in patients of different age groups. MethodsRetrospective inclusion of patients who underwent CABG at Tongji Medical College Affiliated Union Hospital of Huazhong University of Science and Technology from 2016 to 2020. Divided into four groups by age (<50 years, 50-60 years, 60-70 years, >70 years). Propensity score matching (PSM) was used to balance the baseline characteristics of PAD and non PAD patients across different age groups. The primary endpoint of the study was all-cause mortality, and the secondary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) during the perioperative period. ResultsTotally, 1 516 patients were enrolled, including the GroupⅠ (<50 years, n=167), Group Ⅱ (50-60 years, n=477), Group Ⅲ (60-70 years, n=688), and Group Ⅳ (>70 years, n=184). After PSM treatment, a total of 375 pairs of patients (75.2% male) were successfully matched. Only in the age group of 60-70 years, the in-hospital mortality rate (7.73% vs. 1.45%, P＜0.01) and MACCE incidence rate (21.26% vs. 13.04%, P=0.02) of PAD patients were significantly higher than those of the non PAD group. Further multivariate analysis suggests that PAD is an independent risk factor for in-hospital mortality (OR=3.96, P＜0.01) and MACCE (OR=1.58, P=0.04) in this group, while there is no statistically significant difference in other age groups. Conclusion: PAD significantly increases the risk of recent mortality and MACCE in CABG patients aged 60-70 years, and perioperative management needs to be optimized for this population.

Heritable aortic disease (HAD) is characterized by thoracic aortic aneurysm/dissection with strong genetic predisposition and high clinical phenotypic heterogeneity. HAD is one of the main causes of sudden death. Early diagnosis of this disease is difficult because of atypical clinical symptoms, leading to the deterioration of disease with the development of aortic aneurysm, aortic dissection or sudden death. Genetic testing plays an important role in the early diagnosis, standardized follow-up, screening of family members, genetic counseling and individualized treatment of HAD. This review focused on the application of genetic testing in the standardized diagnosis and treatment of HAD.
