The value of viscoelastic platelet function measurements with Sonoclot in patients with acute coronary syndrome undergoing percutaneous coronary intervention

Abstract Purpose Platelets play an important role in the pathogenesis of acute coronary syndrome (ACS), and adequate platelet inhibition is a cornerstone during invasive management with percutaneous coronary intervention (PCI). Despite this, pivotal role routine measurement of platelet function is not done. We aimed at using the using the Sonoclot device for measuring platelet activity and predicting outcome in patients with ACS undergoing PCI. Methods This was a cohort longitudinal study involving 50 patients who were admitted with ACS and undergoing emergent PCI in the critical care department at Cairo University from November 2020 to July 2021. Three parameters will be obtained: platelet function, ACT, and coagulation rate. Results According to the 1st parameter (platelet function), adequate platelet inhibition was achieved in 54% of our cases. To study the impact of this analysis, our population was classified into 2 groups (well-inhibited platelets vs. poorly inhibited platelets). The 2nd and 3rd parameters (ACT, CR) could separate our patients into 2 groups according to whether patients were well anticoagulated or not. Classification 1, well vs. poorly inhibited platelets, both groups were comparable. However, epicardial coronary flow (TIMI flow) and myocardial blush grade post-stenting were better in the well-inhibited platelets group. Classification 2, well vs. poor anticoagulation, there were no significant differences between the 2 groups. Conclusion Adequate platelet inhibition as measured by Sonoclot device can predict better outcomes in patients with ACS undergoing PCI.
