Objective To formulate an individualized evidence-based treatment for a first-diagnosed patient with coronary artery-pulmonary artery fistula. Methods Aiming at the issue of whether interventional operation was necessary for first-diagnosed coronary artery-pulmonary artery fistula or not, the computer retrieval was conducted in the US National Guideline Clearinghouse, The Cochrane Library, PubMed and MEDLINE from 1990 to 2011, to collect and assess the best evidence of relevant systematic reviews, randomized controlled trials, controlled clinical trials and treatment guidelines, in order to be applied in clinical treatment. Results There were 1 clinical guideline for treating coronary artery fistula and 3 different high-quality evidence studies were retrieved. The results showed percutaneous coronary intervention was the best treatment currently. According to the obtained evidence and patient’s willingness, the relevant examinations were taken, and the preoperative preparation for percutaneous coronary intervention was done actively after the patient was admitted. Three days after hospitalization, the selective coronary angiography showed right coronary artery-pulmonary artery fistula and left coronary circumflexus artery-left atrial multiple fistulae, then the percutaneous coronary intervention spring coil embolization was successfully conducted for right coronary artery-pulmonary artery fistula. After operation, bayasprin enteric-coated tablets 0.1 g/d was taken for anti-platelet aggregation and preventing thrombotic diseases. The observation during operation and postoperative 5-day hospitalization showed no relevant complications. Conclusion Percutaneous coronary intervention is safe and effective for the symptomatic patients with coronary artery-pulmonary artery fistula.
ObjectiveTo summarize our experience of emergency coronary artery bypass grafting (CABG) for the treatment of coronary accidents during percutaneous coronary intervention (PCI). MethodsFrom January 2011 to January 2013, 30 patients with coronary accidents during PCI from our hospital and other hospitals received surgical treatment in Xinhua Hospital, Medical School of Shanghai Jiaotong University. There were 21 male and 9 female patients with their age of 68±11 (54-84) years. Coronary accidents included coronary artery dissection in 12 patients, coronary artery perforation in 12 patients, acute in-stent thrombosis in 2 patients, dilation balloon rupture in 1 patient and balloon retention in 1 patient, and PCI guidewire retention in 2 patients. Among the 30 patients, 8 patients received intra-aortic balloon pump (IABP) implantation preoperatively. All the patients underwent emergency CABG, including 29 patients undergoing off-pump CABG and 1 patient undergoing CABG on pump with heart beating. The patients' medical history, PCI and surgical records were retrospectively reviewed, and surgical treatment strategies, clinical outcomes and prognosis were summarized. ResultsThe average number of grafts was 2.8±0.4. Postoperative length of ICU stay was 8.3±4.8 days, and mean hospital stay was 20.3±15.2 days. Postoperative complications included low cardiac output syndrome (LCOS) in 3 patients, tracheotomy in 2 patients, acute renal failure requiring continuous renal replacement therapy in 2 patients, and reexploration for bleeding in 1 patient. Twenty-eight were discharged, 1 patient died of multiple organ dysfunction syndrome caused by LCOS, and another patient died of refractory ventricular fibrillation. A total of 26 patients were followed up for 10.2±8.3 months and 1 patient died of stroke during the following up. ConclusionEmergency CABG can restore coronary artery blood flow quickly and provide good results for coronary accidents during PCI.
ObjectiveTo investigate the influencing factors of serum NT-proBNP level in elderly patients with acute myocardial infarction (AMI) after PCI, and to analyze its predictive value for the short-term prognosis of patients. MethodsA total of 98 elderly patients with AMI in Zhengzhou central hospital from May 2020 to August 2022 were selected, all of whom underwent PCI. The level of serum NT-proBNP before and after PCI was detected. The level of serum NT-probNP after PCI was ≥125 pg/mL, and the level of serum NT-probNP after PCI was normal. Univariate analysis of the general data of the elevated NT-proBNP group and the normal group, Lasso regression model was used to screen the screening variables, and Logistic regression was used to analyze the influencing factors of serum NT-proBNP level in elderly AMI patients after PCI. The prognosis recovery of patients with different NT-proBNP and the level of NT-proBNP in patients with different prognosis were compared and analyzed. ROC curve was drawn to analyze the predictive value of NT-proBNP level in patients with short-term prognosis after PCI. ResultsLogistic regression analysis showed that the time from onset to PCI, age, left ventricular ejection fraction (LVEF), stroke, number of stents implanted, no recirculation and stent diameter were the influencing factors of serum NT-proBNP level in elderly AMI patients after PCI. The incidence of adverse cardiovascular events (MACE) was 21.43% (21/98) in 98 patients followed up 6 months after surgery, and the incidence of NT-proBNP increased group was 68.00% (17/25), which was significantly higher than that of normal group (5.48% (4/73) (P<0.05). The level of NT-proBNP in the group with MACE was significantly higher than that in the group without MACE (P<0.05). ROC curve showed that AUC was 0.813 (95%CI 0.721 to0.884), sensitivity and specificity were 80.95% and 79.22%, respectively, suggesting that serum NT-proBNP level after PCI had certain predictive value for short-term prognosis of patients. ConclusionSerum NT-proBNP level in elderly AMI patients after PCI has a good ability to predict the short-term prognosis of patients. Comprehensive consideration of the number of stents inserted, the presence of stroke, the presence of reflow and age and other factors to strengthen the monitoring of NT-proBNP level is helpful to prevent and control the occurrence of MACE, so as to improve the prognosis of patients.
ObjectiveTo systematically review the effect of compound Danshen dripping pills combined with Western medicine on inflammatory factors and cardiac function after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction.MethodsDatabases including CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, EMbase and The Cochrane Library were searched for randomized controlled trials of compound Danshen dripping pills combined with Western medicine in the treatment of acute myocardial infarction after PCI. The retrieval time was from the establishment of the databases to June 11th, 2020. Two reviewers independently screened literature, extracted data and evaluated the risk bias of included studies. RevMan 5.3 software was used for meta-analysis.ResultsA total of 16 studies were included, involving 2 069 patients. The results of the meta-analysis showed that the combination of compound Danshen dripping pills could increase the left ventricular ejection fraction (MD =−4.74, 95%CI 4.07 to 5.42, P<0.01), decrease the B-type natriuretic peptide (SMD=−3.81, 95%CI −5.06 to −2.57, P<0.01), the level of interleukin-6 (SMD=−3.20, 95%CI −4.54 to −1.86, P<0.01) and level of tumor necrosis factor-a (SMD=−4.96, 95%CI −7.03 to −2.89, P<0.01).ConclusionsCurrent evidence suggests that the combination of compound Danshen dropping pills has potential benefits in inhibiting inflammation and improving cardiac function after PCI. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectivesTo evaluate the efficacy and safety of four antiplatelet regimens after coronary drug-eluting stents by network meta-analysis.MethodsPubMed, The Cochrane Library, EMbase and Web of Science databases were electronically searched to collect randomized controlled trials (RCTs) of the comparison of different antiplatelet regimens after coronary drug-eluting stenting from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Network meta-analysis was then performed by using Gemtc14.3 software, Stata16.0 software and RevMan5.3 software.ResultsA total of 23 RCTs involving 45 837 patients were included. The results of network meta-analysis showed that: in terms of prevention of myocardial infarction (MI) recurrence, the aspirin monotherapy after short-term dual antiplatelet therapy was inferior to the triple antiplatelet therapy (OR=2.13, 95%CI 1.08 to 4.03). In terms of reducing the incidence of ischemic compound events, the triple antiplatelet therapy was superior to the standard dual antiplatelet therapy (OR=0.53, 95%CI 0.39 to 0.72), the aspirin monotherapy after short-term dual antiplatelet therapy (OR=0.49, 95%CI 0.35 to 0.69) and the P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy (OR=0.51, 95%CI 0.35 to 0.73). There was no statistically significant difference among the four interventions in reducing the rate of in-stent thrombosis and all-cause mortality (P>0.05). In terms of safety, the bleeding rate of aspirin monotherapy after short-term dual antiplatelet therapy was lower than that of standard dual antiplatelet therapy (OR=0.70, 95%CI 0.55 to 0.86) and triple antiplatelet therapy (OR=0.58, 95%CI 0.36 to 0.90), and the bleeding rate of P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy was also lower than that of standard dual antiplatelet therapy (OR=0.51, 95%CI 0.39 to 0.65) and triple antiplatelet therapy (OR=0.43, 95%CI 0.26 to 0.67). The probability ranking diagram showed that: in terms of the recurrence rate of MI, the rate of in-stent thrombosis and the incidence of ischemic compound events, triple antiplatelet therapy was the lowest and aspirin monotherapy after short-term dual antiplatelet therapy was the highest. However, in terms of all-cause mortality and bleeding rate, aspirin or P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy was the lowest and triple antiplatelet therapy was the highest.ConclusionsThe available evidence suggests that when the risk of ischemia is low, we should choose aspirin or P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy, and P2Y12 inhibitor monotherapy may have a lower risk of ischemia and bleeding. When the risk of ischemia is high and bleeding is low, the triple or standard dual antiplatelet therapy should be selected, and the efficacy of triple antiplatelet therapy is superior, while the safety may be inferior.
Objective To systematically review the angiographic predictors of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Methods The PubMed, EMbase, Cochrane Library, Web of Science, CBM, WanFang Data, and CNKI databases were electronically searched to collect observational studies on the angiographic predictors of CTO-PCI from inception to December 18, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.4 software. Results A total of 36 studies were included. The results of meta-analysis showed that the angiographic predictors of CTO-PCI included calcification (OR=1.92, 95%CI 1.49 to 2.47, P<0.01), occlusion length≥20mm (OR=1.80, 95%CI 1.26 to 2.57, P<0.01), bending>45° (OR=2.19, 95%CI 1.56 to 3.08, P<0.01), blunt stump (OR=1.53, 95%CI 1.08 to 2.16, P<0.01), ostial lesions (OR=2.27, 95%CI 1.34 to 3.85, P<0.01), proximal cap ambiguity (OR=2.27, 95%CI 1.40 to 3.68, P<0.01), side branch at proximal cap (OR=1.65, 95%CI 1.27 to 2.16, P<0.01), and J-CTO score≥3 (OR=2.53, 95%CI 1.53 to 4.16, P<0.01). Conclusion Current evidence indicates that calcification, occlusion length ≥20mm, bending>45°, blunt stump, ostial lesions, proximal cap ambiguity, side branch at proximal cap, and J-CTO score≥3 are the angiographic predictors of CTO-PCI. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Abstract： Objectives To evaluate the early and mid-term follow-up outcomes of “one-stop” hybrid coronary revascularization strategy for patients with multivessel coronary artery disease. Methods From June 2007 to December 2009, 104 consecutive patients underwent “one-stop”hybrid coronary revascularization in Fu Wai Hospital. There were 93 male patients and 11 female patients with mean age of （61.8±10.2）years（ranging from 35 to 81 years）. All the patients had multivessel coronary artery disease including left anterior descending （LAD）coronary artery stenosis, and underwent “one-stop”hybrid coronary revascularization. “One-stop”hybrid procedure was first performed through a lower partial sternotomy at the second left intercostal space. The distal anastomosis of in situ left internal mammary artery （LIMA）to LAD graft was completed. Angiography was performed immediately to confirm patency of the LIMA graft after closure of the thorax. A 300 mg loading dose of clopidogrel was administered through a nasogastric tube after confirmation of LIMA graft patency. Intravenous unfractionated heparin was administered to obtain an activated clotting time of greater than 250 s. Then percutaneous coronary intervention（PCI）was performed on the non-LAD lesions. Results All the patients underwent“one-stop”hybrid coronary revascularization including grafted LIMA to LAD，and one hundred and ninety one drug eluting stents and three bare metal stents were used for other non-LAD lesions. No death event occurred during surgery and in hospital. All the patients were followed up for a mean duration of 1.5 years. There was no myocardial infarction, neurologic event or death occurred during follow-up except one patient with stent stenosis who was treated by PCI. Conclusion “One-stop” hybrid coronary revascularization is a feasible and safe alternative for patients with multivessel coronary artery disease.
ObjectiveTo analyze systematic reviews (SRs) and meta-analyses on the efficacy of pharmacological interventions in the prevention of contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI). MethodsWe searched the PubMed, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data, and VIP databases to identify SRs and meta-analyses on the pharmacological interventions aimed at preventing CI-AKI after PCI from inception of the databases to February 2022. Two researchers independently screened the literature and extracted data. The PRISMA statement, AMSTAR 2 tool, and GRADE system were adopted to evaluate the reporting quality, methodological quality, and evidence quality of the findings of the included SRs and meta-analyses. ResultsA total of 14 SRs and meta-analyses were identified. Among the drugs used were statins, N-acetylcysteine, sodium bicarbonate, Dan-hong injection, vitamins, salvianolate, adenosine antagonists, nicorandil, allopurinol, alprostadil, furosemide, trimetazidine, probucol, and brain natriuretic peptide. Most of the studies had relatively comprehensive coverage of the items, with the PRISMA scores ranging from 18 to 24.5. The main issues of reporting quality were protocol and registration, search, and funding. The methodological quality of the SRs and meta-analyses was generally low. Items 2 and 7 were the key items with poor scores, and the non-critical items with poor scores were items 3, 10, and 16. All drugs, except furosemide, decreased the incidence of CI-AKI. The quality of evidence ranged from medium to very low according to GRADE. Conclusion Most of the single drugs or drugs combined with hydration show the potential to prevent CI-AKI, however, the overall methodological quality of the included studies is relatively low, and the strength of evidence is generally low.
Objective To systematically review the efficacy and safety of minimally invasive direct coronary artery bypass (MIDCAB) grafting versus percutaneous coronary intervention (PCI) for patients with single-vessel disease of the left anterior descending artery (LAD). Methods Databases including The Cochrane Library (Issue 2, 2015), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were searched electronically from inception to Oct. 2015, to collect randomized controlled trials (RCTs) about MIDCAB versus PCI for single-vessel disease of the LAD. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results A total of 10 RCTs including 1 489 patients were included. The results of meta-analysis showed that: compared with the PCI group, the MIDCAB group could significantly reduce the incidence of postoperative target vessel revascularization (OR=0.20，95%CI 0.13 to 2.29，P < 0.000 01), and the incidence of main adverse cardiovascular and cerebrovascular events (MACCE) (OR=0.44, 95%CI 0.33 to 0.58, P < 0.000 01). No significant differences were found between the two groups in total case mortality (OR=1.23, 95%CI 0.83 to 1.83, P=0.31), cardiogenic death (OR=1.12, 95%CI 0.59 to 2.12, P=0.73), and the incidence of postoperative myocardial infarction (OR=2.16, 95%CI 0.83 to 5.59, P=0.11). Conclusion In reducing the incidences of postoperative target vessels again revascularization and MACCE of patients with single-vessel disease of the LAD, MIDCAB is superior to PCI. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.
ObjectiveTo systematically review the efficacy and safety of primary percutaneous coronary intervention (PCI) via radial access versus via femoral access for patients with acute ST-segment elevation myocardial infarction (STEMI). MethodsRandomized controlled trials (RCTs) about the clinical efficacy and safety of radial access for PCI in patients with acute STEMI were searched in PubMed, EMbase, CBM, The Cochrane Library (Issue 6, 2014), CNKI, VIP, and WanFang Data from 2000 to November 2014. Literature screening according to the inclusion and exclusion criteria, data extraction and methodological quality assessment of included studies were completed by two reviewers independently. Then meta-analysis was conducted using RevMan 5.2 software. ResultsA total of fourteen RCTs involving 5 212 patients were enrolled. The results indicated that:a) radial access was associated with decreased risks of mortality (OR=0.54, 95%CI 0.40 to 0.74, P=0.000 1); decreased incidences of major bleeding (OR=0.50, 95%CI 0.34 to 0.74, P=0.000 8), major adverse cardiac events (MACE) (OR=0.65, 95%CI 0.50 to 0.83, P=0.000 6), and puncture site complications (OR=0.35, 95%CI 0.25 to 0.49, P < 0.000 01); and decreased hospital duration (MD=-2.14, 95%CI-3.97 to-0.31, P=0.002). b) However, the two groups were alike in the success rate of operation, exposure time of X ray, risk of stroke, and the rate of CABG. PCI via radial access took more operation time than that via femoral access, and PCI via radial access had a higher incidence of changing puncture access. ConclusionFor acute STEMI patients undergoing PCI, radial access could significantly reduce mortality, and incidences of major bleeding, MACE and puncture site complications. Therefore, under the conditions of strict indication control and increased operation skills, PCI via radial access is effective and safe in the treatment of acute STEMI. Due to limited quality and quantity of the included studies, more large-scale, multi-centre, high quality RCTs are needed to verify the above conclusion.
