AIM: The present investigation was aimed at assessing the prognostic impact of renal dysfunction rate in STEMI patients submitted to thrombectomy (TP).
METHODS: Out of 1268 consecutive ST elevation myocardial infarction (STEMI) patients treated with pPCI from January 1rst 2004 to December 31th 2012 in our hospital 671 patients (52.9%) underwent adjunctive thrombus aspiration and constituted the study population. Patients were divided into three groups according to eGFR: group 1 included patients with eGFR>60 mL/min/m2, group 2 eGFR>30 mL/min/m2 and <60 mL/min/m2, group 3 eGFR<30 mL/min/m2. The rate of utilization of thrombectomy, the rate of pPCI failure and the incidence of major bleeding were assessed in each subgroup. Patients in group 3 and group 2 were less likely to be submitted to TP, while more than 50% of patients with normal eGFR underwent TP (overall P=0.019). The rate of pPCI failure was significantly higher in group 2 and 3 when compared to group 1 (P=0.002). Worsening renal failure was associated with a higher mortality rate both at ICCU and at 1 year follow-up (P<0.001 and P<0.001, respectively). A higher incidence of major bleedings was reported in group 2 and group 3, despite the lower administration of glycoprotein IIb/IIIa inhibitors (P<0.001). Moderate and severe renal impairment was associated with a higher mortality rate both at ICCU and at 1 year follow-up (P<0.001 and P<0.001, respectively).
CONCLUSION: Thrombus aspiration is less like to be performed among patients with impaired renal function. Despite thrombus aspiration patients with reduced eGFR showed a higher incidence of pPCI failure.
