Key result
Aspiration thrombectomy with primary stenting significantly increased the rate of complete ST-segment resolution compared to primary stenting alone (90% vs 64%, p<0.01) in patients with acute myocardial infarction.
Why the study?

Does aspiration thrombectomy using the Diver C.E. MAX catheter improve ST segment resolution and LVEF in patients with acute myocardial infarction undergoing primary PCI?
Aspiration thrombectomy prior to primary stenting in acute myocardial infarction significantly improves ST-segment resolution and myocardial perfusion compared to standard PCI, though it does not significantly alter short-term LVEF.

May improve ST resolution in AMI; hypothesis-generating and should not change practice without RCTs.
Objectives: To evaluate the effects of aspiration thrombectomy (AT) using anAspiration Catheter (INVATEC SPA DIVER C.E. MAX, Italy) in patients with acute myocardialinfarction (AMI). Study Design: Cross sectional and Case series study. Setting: Departmentof Cardiology, Liaquat University Hospital, Hyderabad. Period: January 2012 to December2013. Methodology and Results: Measurement of left ventricular ejection fraction (LVEF) byechocardiography was obtained before (acute LVEF) percutaneous coronary intervention (PCI)and 1 week after (late LVEF) the procedure. Most of the patients with full restoration of STsegment elevation following PCI were higher in the aspiration Catheter control group (90 vs68%, P < 0.01), (86 vs 62%, P < 0.01) and (90 vs 64%, P < 0.01) respectively. Minimal changein LVEF was observed in patients between the Aspiration Catheter group and control group at1 week post procedure. Conclusion: Combination of AT using Aspiration Catheter (INVATECSPA DIVER C.E. MAX) with primary stenting can better outcome, while left ventricle (LV) functionhad subtle change in AMI when compared to primary stenting after balloon predilation withoutthrombectomy.

Tariq et al. (2018) conducted a cross-sectional in Acute Myocardial Infarction (n=136). Aspiration thrombectomy (DIVER C.E. MAX) with primary stenting vs. Primary stenting alone was evaluated on Complete restoration of ST segment elevation (p=<0.01). Aspiration thrombectomy with primary stenting significantly increased the rate of complete ST-segment resolution compared to primary stenting alone (90% vs 64%, p<0.01) in patients with acute myocardial infarction.
