N2 - Randomized clinical trials that examined long-term clinical outcomes of routine aspiration thrombectomy prior to primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction have yielded different results. We hypothesized that the routine use of manual thrombus aspiration prior to primary PCI lacks long-term clinical benefits. Electronic databases were searched for randomized trials comparing routine aspiration thrombectomy and conventional PCI. We included only trials that reported clinical outcomes beyond 6 months. The primary outcome was all-cause mortality, and the secondary outcomes included major adverse cardiovascular events, re-infarction, cardiovascular mortality, and stent thrombosis (ST). A DerSimonian-Laird model was used to construct the summary estimates risk ratio (RR). We retrieved 18 trials with 20 641 ST-segment elevation myocardial infarction patients, of whom 10 331 patients underwent routine aspiration thrombectomy prior to primary PCI. At a mean follow-up of 12 months, there was no significant decrease in the risk of all-cause mortality (RR: 0.93, 95% confidence interval [CI]: 0.82-1.05, P = 0.22), major adverse cardiac events (RR: 0.95, 95% CI: 0.87-1.03, P = 0.18), re-infarction (RR: 0.95, 95% CI: 0.80-1.13, P = 0.59), cardiovascular mortality (RR: 0.80, 95% CI: 0.47-1.36, P = 0.40), or ST (RR: 0.80, 95% CI: 0.63-1.01, P = 0.06) with routine aspiration thrombectomy. Routine aspiration thrombectomy prior to primary PCI was not associated with a reduction in long-term mortality or clinical outcomes. Future randomized trials are warranted to further evaluate the role of aspiration thrombectomy in select patients and coronary lesions.
