Clinical impact of direct stenting and interaction with thrombus aspiration in patients with ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention : Thrombectomy Trialists Collaboration
Aims Preliminary studies suggest that direct stenting (DS) during percutaneous coronary intervention (PCI) may reduce microvascular obstruction and improve clinical outcome. Thrombus aspiration may facilitate DS. We assessed the impact of DS on clinical outcome and myocardial reperfusion and its interaction with thrombus aspiration among ST-segment elevation myocardial infarction (STEMI) patients undergoing PCI. Methods and results Patient-level data from the three largest randomized trials on routine manual thrombus aspiration vs. PCI only were merged. A 1:1 propensity matched population was created to compare DS and conventional stenting. Synergy between DS and thrombus aspiration was assessed with interaction P-values in the final models. In the unmatched population (n= 17 329), 32% underwent DS and 68% underwent conventional stenting. Direct stenting rates were higher in patients randomized to thrombus aspiration as compared with PCI only (41% vs. 22%; P < 0.001). Patients undergoing DS required less contrast (162mL vs. 172mL; P< 0.001) and had shorter fluoroscopy time (11.1min vs. 13.3 min; P< 0.001). After propensity matching (n= 10 944), no significant differences were seen between DS and conventional stenting with respect to 30-day cardiovascular death [1.7% vs. 1.9%; hazard ratio 0.88, 95% confidence interval (CI) 0.55-1.41; P=0.60; Pinteraction = 0.96) and 30-day stroke or transient ischaemic attack (0.6% vs. 0.4%; odds ratio 1.02; 95% CI 0.14-7.54; P=0.99; Pinteraction = 0.81). One-year results were similar. No significant differences were seen in electrocardiographic and angiographic myocardial reperfusion measures. Conclusion Direct stenting rates were higher in patients randomized to thrombus aspiration. Clinical outcomes and myocardial reperfusion measures did not differ significantly between DS and conventional stenting and there was no interaction with thrombus aspiration

Thrombus Aspiration in ST Elevation Myocardial Infarction : An Individual Patient Meta-analysis
BACKGROUND—: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with STEMI. METHODS—: Included were large (N≥1000) randomized controlled trials comparing manual thrombectomy vs. PCI alone in patients with STEMI. Individual patient data was provided by the leadership of each trial. The pre-specified primary efficacy outcome was cardiovascular (CV) mortality within 30 days and the primary safety outcome was stroke or transient ischemic attack (TIA) within 30 days. RESULTS—: The 3 eligible randomized trials (TAPAS, TASTE and TOTAL) enrolled 19,047 patients, of whom 18,306 underwent PCI and were included in the primary analysis. CV death at 30 days occurred in 221 (2.4%) of 9155 patients randomized to thrombus aspiration and 262 (2.9%) of 9151 randomized to PCI alone (hazard ratio (HR) 0.84; 95% CI 0.70-1.01, p=0.06). Stroke or TIA occurred in 66 (0.8%) randomized to thrombus aspiration and 46 (0.5%) randomized to PCI alone (odds ratio [OR] 1.43 95% CI 0.98-2.1, p=0.06). There were no significant differences in recurrent myocardial infarction, stent thrombosis, heart failure or target vessel revascularization. In the subgroup with high thrombus burden (TIMI thrombus grade ≥3) thrombus aspiration was associated with less CV death (170 [2.5%] vs. 205 [3.1%] HR 0.80; 95% CI 0.65-0.98, p =0.03), and with more stroke or TIA (55 [0.9%] vs. 34 [0.5%] OR 1.56; 95% CI 1.02-2.42, p=0.04). However, the interaction p-values were 0.32 and 0.34, respectively. CONCLUSIONS—: Routine thrombus aspiration during STEMI PCI did not improve clinical outcomes. In the high thrombus burden subgroup the trends toward reduced CV death and increased stroke or TIA provide a rationale for future trials of improved thrombus aspiration technologies in this high-risk subgroup.
