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 evaluate the clinical efficacy and safety of triple-antiplatelet treatment based on Cilostazol for restenosis after percutaneous coronary intervention. Methods?We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2009), PubMed (1966 to 2009), EMbase (1974 to 2009), CNKI (1994 to 2009), CBM (1978 to Feb. 2009), VIP (1989 to Feb. 2009), and CMD Digital Periodicals (1998 to 2009). Two reviewers independently evaluated the quality of the included studies and extracted the data. Meta-analyses were performed using RevMan 5.0 software. Results?Five randomized controlled trials (RCTs) involving 2 348 patients were included. The results of meta-analyses showed that triple-antiplatelet treatment based on Cilostazol could increase minimum lumen diameter (MD=0.31, 95%CI 0.11 to 0.51) and decrease restenosis rate (OR=0.49, 95%CI 0.37 to 0.65). In addition, it could decrease death rate (OR=0.52, 95%CI 0.31 to 0.88), but it could not change target-vessel revascularization, stroke rate, palpitation rate, and the rate of major adverse cardiac and cerebral events and major adverse cardiac events. Conclusion?Evidence shows that triple-antiplatelet treatment based on Cilostazol could increase minimum lumen diameter and decrease restenosis rate and death rate. Their clinical application is worthy to be advocated.
Objectives
To systematically review the efficacy and safety of clopidogrel 600 mg and 300 mg loading dose in Chinese patients underwent percutaneous coronary intervention (PCI).
Methods
We searched The Cochrane Library, EMbase, PubMed, CNKI, WanFang Data, CBM and VIP databases to collect randomized controlled trials (RCTs) of the efficacy and safety of clopidogrel 600 mg and 300 mg loading dose in Chinese patients underwent PCI from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 14.0 software.
Results
A total of 10 RCTs involving 1 166 patients were included. The results of meta-analysis showed that: the 600 mg loading dose group had lower incidence rate of major adverse cardiovascular events (MACE) in comparison with the 300 mg loading dose group (RR=0.29, 95%CI 0.17 to 0.48, P<0.000 1). However, no significant difference was found in the incidence of major bleeding events within 30 days between two groups (RR=1.64, 95%CI 0.70 to 3.80,P=0.252).
Conclusions
The current evidence shows that in Chinese patients underwent PCI, administration of a 600 mg loading dose of clopidogrel is associated with a lower risk of MACE than is administration of a 300 mg loading dose of clopidogrel, without increasing major bleeding risk in 30 days. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
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.
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 systematically review the efficacy and safety of triple antiplatelet therapy (TAT:aspirin, clopidogrel and cilostazol) for patients with coronary heart diseases after percutaneous coronary intervention.
MethodsSuch databases as The Cochrane Library (Issue 2, 2014), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data were electronically searched for relevant randomized controlled trials (RCTs) on the efficacy and safety of TAT for patients with coronary heart diseases after percutaneous coronary intervention from inception to February 2014. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software.
ResultsA total of 15 RCTs involved 6 980 patients were included. The results of meta-analysis showed that:a) the DAT group (DAT:aspirin and clopidogrel) and the TAT group were similar in non-fatal myocardial infarction (OR=0.72, 95%CI 0.47 to 1.10, P=0.05), stroke (OR=0.66, 95%CI 0.38 to 1.16, P=0.15), and hemorrhage (OR=1.03, 95%CI 0.74 to 1.44, P=0.85) with no significant difference; b) the TAT group was superior to the DAT group in reducing the incidences of the major cardiovascular and cerebrovascular events (MACCE) (OR=0.50, 95%CI 0.39 to 0.65, P < 0.000 01), cardiac death (OR=0.53, 95%CI 0.33 to 0.84, P=0.007), stent thrombosis (OR=0.52, 95% CI 0.27 to 0.99, P=0.05), target vessel revascularization (OR=0.63, 95%CI 0.51 to 0.76, P < 0.000 01), and target lesion revascularization (OR=0.44, 95%CI 0.28 to 0.70, P=0.000 6); and c) no significant difference was found between the two groups in the incidences of thrombocytopenia, leucopenia, and liver damage. The DAT group was superior to the TAT group in gastrointestinal reaction, palpitations, headache, and skin rashes between the two groups, with significant differences.
ConclusionTAT therapy has good efficacy and safety in the treatment of patients with coronary heart diseases after percutaneous coronary intervention.
ObjectiveCompare the therapeutic effects of multivessel percutaneous coronary intervention (MV-PCI) and culprit-only revascularization strategy (C-PCI) in percutaneous coronary intervention (PCI) for patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) and multivessel disease (MVD). MethodsThe PubMed, Embase, Cochrane Library, MEDLINE, Web of Science, CENTRAL, CNKI and WanFang Data databases were searched to collect studies comparing C-PCI vs. MV-PCI in patients with AMI and CS from inception to March 2, 2025. Methodological quality of the included studies was assessed using the Newcastle-Ottawa scale (NOS) and the risk of bias (ROB) tool. Meta-analysis was performed using RevMan software (version 5.4.0). ResultsA total of 18 studies (1 randomized controlled trial, 1 post-hoc analysis of a randomized controlled trial, and 16 retrospective observational studies), enrolling 101 693 patients. The results of the observational studies showed that MV-PCI was associated with higher risk of short-term mortality (OR=1.13, 95%CI 1.01 to 1.25, P=0.03), renal replacement therapy (OR=1.41, 95%CI 1.32 to 1.50, P<0.00001), and cerebrovascular accident events (OR=1.21, 95%CI 1.10 to 1.33, P=0.0001). No significant difference was observed in long-term mortality (OR=0.93, 95%CI 0.74 to 1.16, P=0.51), recurrent myocardial infarction (OR=1.16, 95%CI 0.97 to 1.39, P=0.10), repeat revascularization events (OR=0.83, 95%CI 0.58 to 1.20, P=0.33) and bleeding event rates (OR=1.01, 95%CI 0.71 to 1.34, P=0.97) between groups. The results remained consistent after adding the only randomized trial.ConclusionsIn patients with AMICS and concomitant MVD, C-PCI provides comparable survival benefits to MV-PCI and is associated with a reduced risk of all-cause mortality, cerebrovascular events, and the need for renal replacement therapy.
Objective To evaluate the effectiveness and security through meta-analysis of a comprehensive study of efficacy of coronary artery bypass grafting (CABG) versus drug-eluting stent percutaneous coronary intervention (DES-PCI), for diabetes mellitus with multi-vessel coronary disease. Methods Databases including The Cochrane Library, PubMed, MEDLINE, EMbase, CBM, CNKI, WanFang Data and VIP were searched from their establishment dates to 2010. Published information and conference papers including references were handsearched. Relevant randomized controlled trials (RCTs) on diabetic patients with coronary multi-vessel disease treated with revascularization were collected and screened by two reviewers independently. After data extraction and quality assessment of the included studies, meta-analysis was performed using RevMan 5.0. Results A total of eight studies involving a total of 3 689 cases (CABG group: 1 814 cases; DES-PCI group: 1 875 cases) were included. Results of meta-analyses showed that: compared with the DES-PCI group, the CABG group could significantly reduce postoperative repeat revascularization rate (OR=0.27, 95% CI 0.10 to 0.69, P=0.006) and major cardio-cerebral vascular events (OR=0.49, 95% CI 0.38 to 0.62, Plt;0.000 01). But in reducing mortality rate (OR=0.84, 95%CI 0.64 to 1.10, P=0.21), cerebrovascular events (OR=2.00, 95%CI 0.97 to 4.14, P=0.06) and myocardial infarction incidence rate (OR=0.92, 95%CI 0.53 to 1.59, P=0.75), there were no significant differences between the two groups. Conclusion CABG is superior to DES-PCI in the treatment of diabetic patients with multi-vessel disease. However, due to the limitation of the quality and quantity of the included studies, the above conclusion should be tested by conducting more large-scale, multi-center and prospective RCTs in future.
Objective To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.
