ACUTE MYOCARDIAL INFARCTION

SHORT-TERM EFFECT OF SUCCESSFUL ASPIRATION IN PRIMARY STENTING ON PATIENTS WITH ACUTE MYOCARDIAL INFARCTION

Abstract

Objectives: To evaluate the effects of aspiration thrombectomy (AT) using an
Aspiration Catheter (INVATEC SPA DIVER C.E. MAX, Italy) in patients with acute myocardial
infarction (AMI). Study Design: Cross sectional and Case series study. Setting: Department
of Cardiology, Liaquat University Hospital, Hyderabad. Period: January 2012 to December
2013. Methodology and Results: Measurement of left ventricular ejection fraction (LVEF) by
echocardiography 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 ST
segment elevation following PCI were higher in the aspiration Catheter control group (90 vs
68%, P < 0.01), (86 vs 62%, P < 0.01) and (90 vs 64%, P < 0.01) respectively. Minimal change
in LVEF was observed in patients between the Aspiration Catheter group and control group at
1 week post procedure. Conclusion: Combination of AT using Aspiration Catheter (INVATEC
SPA DIVER C.E. MAX) with primary stenting can better outcome, while left ventricle (LV) function
had subtle change in AMI when compared to primary stenting after balloon predilation without
thrombectomy.
