Aim: Is to evaluate the value of thrombus aspiration devices in primary PCI compared to conventional primary PCI on intermediate and short term follow up.
Patients and methods: The study included 60 patients with acute myocardial infarction undergoing primary PCI, all patients submitted to history taking, general and local examination, ECG before procedure and 90 min after, Echocardiography to 24th and 1 month after procedure then before diagnostic angiography was performed, patients were divided randomly into: group A: 30 patients subjected to primary PCI only and group B: 30 patients subjected to thrombectomy device before primary PCI.
Results: There was no difference between two groups as regard to age, gender, risk factors or time from symptom onset to CCU admission. There was significant improvement in the TIMI flow grade after PPCI but there was no significant difference between two groups. Thrombus aspiration was successful in achieving significant better reperfusion by myocardial blush grade (MBG) as 96% in group B had MBG ≥2 while only 80% in group A achieved MBG ≥2 (p=0.02). Although there was no difference in the myocardial salvage predictors as regard to TIMI flow grade 3 (p=0.3) or EF% (p=0.74) but MBG ≥2 and ST resolution (STR) was higher in group A (p=0.002 and 0.001 respectively).
Conclusion: Thrombectomy device is safe to use before PPCI and although it did not affect the TIMI flow grade or EF% it significantly, it improved the MBG and STR especially when TIMI flow grade was 0. |
