ABSTRACT
Thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) is reported to improve myocardial reperfusion. However, the long-term prognostic implication of TA remains unclear. We aimed to investigate the influence of adjunctive TA on long-term outcomes in ST-segment elevation myocardial infarction (STEMI) patients undergoing PPCI. All STEMI patients from China that included in the TOTAL trial who were ≥18 years old and referred for PPCI within the 12 hours after symptom onset between January 2011 and November 2012 were retrospectively analyzed. Patients were divided into 2 groups based on the use of TA or not. The primary efficacy outcomes were 5-year major adverse cardiac events, a composite of cardiovascular death, recurrent MI, cardiogenic shock, or heart failure hospitalization. The primary safety outcome was a 5-year stroke. A total of 563 patients were included. The incidence rate of major adverse cardiac events at 5 years in the TA group was similar to that in the PCI group (hazard ratio [HR] 0.70; 95% confidence interval [CI] 0.42 to 1.17). In addition, TA was significantly associated with a nearly sevenfold increased risk of stroke at 5 years compared with PCI alone (HR 7.32, 95% CI 1.33 to 40.31). Our propensity scoring match analyses suggested that patients with an occluded lesion might benefit from the TA (HR 0.24, 95% CI 0.08 to 0.70). In conclusion, TA is not associated with improved outcomes in patients with STEMI but may have an adverse impact on stroke. Patients with an occluded infarct-related artery could benefit from the TA.
