Background. Individual randomized trials have suggested that everolimus-eluting stents may have improved clinical outcomes compared to paclitaxel-eluting stents, but individual trials are underpowered to examine outcomes such as mortality and very late stent thrombosis. Methods. Medline, Cochrane, and conference proceedings were searched for randomized trials comparing everolimus versus paclitaxel-eluting stents for percutaneous coronary intervention. Results. 6792 patients were included from 4 randomized controlled trials. Stent thrombosis was reduced with everolimus stents versus paclitaxel stents (0.7% versus 2.3%; OR: 0.32; CI: 0.20–0.51; P<0.00001). The reductions in stent thrombosis were observed in (i) early stent thrombosis (within 30 days) (0.2% versus 0.9%; OR: 0.24; P=0.0005), (ii) late (day 31–365) (0.2% versus 0.6%; OR: 0.32; P=0.01), and (iii) very late stent thrombosis (>365 days) (0.2% versus 0.8%; OR: 0.34; P=0.009). The rates of cardiovascular mortality were 1.2% in everolimus group and 1.6% in paclitaxel group (OR: 0.85; P=0.43). Patients receiving everolimus-eluting stents had significantly lower myocardial infarction events and target vessel revascularization as compared to paclitaxel-eluting stents. Interpretation. Everolimus compared to paclitaxel-eluting stents reduced the incidence of early, late, and very late stent thrombosis as well as target vessel revascularization.

SummaryAlthough bivalirudin has been shown to reduce bleeding events in patients undergoing percutaneous coronary intervention, residual concerns remain about a possible higher risk of early (within 30 days) stent thrombosis (ST). Therefore, we performed a meta-analysis of randomised trials reporting ST events with bivalirudin compared to other antithrombotic therapies (heparins ± glycoprotein IIb/IIIa inhibitors). A systematic literature search of electronic resources was performed through May, 2014. The primary endpoint was definite early ST, according to Academic Research Consortium criteria. Secondary endpoints included: all-cause death, myocardial infarction and major bleeding. A total of 11 trials, including 16,415 patients, were accrued. Compared to other regimens, bivalirudin significantly increased the risk of early ST (odds ratio [OR]=1.80; 95 % confidence interval [CI], 1.28 2.52; p=0.0007) and reduced the risk of major bleeding (OR [95 %CI]=0.64 [0.51 0.82], p=0.0003), with a comparable risk of mortality or myocardial infarction. The higher risk of early ST was mainly attributable to acute (OR [95 % CI] =4.33 [2.33 8.05], p < 0.001) than subacute (OR [95 % CI] =0.89 [0.53 1.50], p =0.67) ST events (p for interaction < 0.001). Non-fatal myocardial infarction was the most common presentation (83 %) of early ST events, while death occurred infrequently (about 5 %). In conclusion, in patients undergoing PCI, bivalirudin compared to heparins is associated with a higher risk of early ST, which is mainly related to more frequent acute events. Further studies are required to evaluate alternative strategies to mitigate this risk, without hampering the benefits derived from the reduction in bleeding events with bivalirudin.

Objective. The effect of postdilation in patients with acute coronary syndrome is still controversial. This meta-analysis aims to analyze the clinical and angiographic outcomes of postdilation after percutaneous coronary intervention in patients with acute coronary syndrome. Methods. PubMed, Embase, the Cochrane Library, Web of Science, CNKI, and Wangfang databases were searched from inception to August 30, 2020. Eligible studies from acute coronary syndrome patients treated with postdilation were included. The primary clinical outcome was major adverse cardiovascular events (MACE), the secondary clinical outcomes comprised all-cause death, stent thrombosis, myocardial infarction, and target vessel revascularization, and the angiographic outcomes were no reflow and slow reflow. Results. 11 studies met inclusion criteria. In clinical outcomes, our pooled analysis demonstrated that the postdilation had a tendency of decreasing MACE (OR = 0.67, 95% CI 0.45–1.00; P  = 0.05) but significantly increased all-cause death (OR = 1.49, 95% CI 1.05–2.12; P  = 0.03). No significant difference existed in stent thrombosis (OR = 0.71, 95% CI 0.40–1.26; P  = 0.24), myocardial infarction (OR = 1.40, 95% CI 0.51–3.83; P  = 0.51), and target vessel revascularization (OR = 0.61, 95% CI 0.21–1.80; P  = 0.37) between postdilation and non-postdilation groups. In angiographic outcomes, there were no significant differences in no reflow (OR = 1.19, 95% CI 0.54–2.65; P  = 0.66) and slow reflow (OR = 1.12, 95% CI 0.93–1.35; P  = 0.24) between two groups. Conclusions. The postdilation tends to reduce the risk of MACE but significantly increases all-cause death, without significantly affecting stent thrombosis, myocardial infarction, target vessel revascularization, and coronary TIMI flow grade. However, more randomized controlled trials are required for investigating the effect of postdilation for patients with acute coronary syndrome (registered by PROSPERO, CRD42020160748).

Background The clinical impact of early aspirin discontinuation compared with dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention with stenting remains poorly studied. We investigated the clinical outcomes of patients assigned to either early aspirin discontinuation or DAPT after percutaneous coronary intervention with stenting. Methods and Results We performed a meta‐analysis of aggregate data from randomized clinical trials enrolling participants receiving a percutaneous coronary intervention with stenting and assigned to either early aspirin discontinuation or DAPT. Scientific databases were searched from inception through March 30, 2020. Trial‐level hazard ratios (HRs) and 95% CIs were pooled using a random effects model with inverse variance weighting. The primary outcome was all‐cause death. Secondary outcomes were myocardial infarction, stent thrombosis, stroke, and major bleeding. Overall, 36 206 participants were allocated to either early aspirin discontinuation (experimental therapy, n=18 088) or DAPT (control therapy, n=18 118) in 7 trials. Median follow‐up was 12 months. All‐cause death occurred in 2.5% of patients assigned to experimental and 2.9% of patients assigned control therapy (hazard ratio [HR], 0.91, 95% CI, 0.75–1.11; P =0.37). Overall, patients treated with experimental versus control therapy showed no significant difference in terms of myocardial infarction (HR, 1.02 [0.85–1.22], P =0.81), stent thrombosis (HR, 1.02 [0.87–1.20], P =0.83), or stroke (HR, 1.01 [0.68–1.49], P =0.96). However, the risk for major bleeding (HR, 0.58 [0.43–0.77], P <0.01) was significantly reduced by experimental as compared with control therapy. Conclusions In patients treated with percutaneous coronary intervention and stenting, assigned to a strategy of early aspirin discontinuation versus DAPT, the risk of death and ischemic events is not significantly different but the risk of bleeding is lower.
