Study Details

Study Description

Brief Summary

Aim of this single center randomized open label trial with blinded in-hospital outcomes assessment is designed with aim to compare manual thrombus aspiration followed by percutaneous coronary intervention (PCI) strategy with PCI alone.

Condition or Disease Intervention/Treatment Phase
  • Device: Export Catheter
  • Device: Balloon catheter
N/A

Detailed Description

Clinical benefit of manual aspiration has been a contentious point of debate and it is Class III indication in current clinical practice guidelines, however, recent observational data by Kumar D et al. showed benefits of usage of export in terms of favorable in-hospital outcomes and lesser complication rate in patients with total occlusion, furthermore, benefits of usage of export was observed to be directly associated with duration of chest pain at the time of thrombus aspiration. However, these observations are limited to immediate and in-hospital outcomes and data regarding efficacy of manual thrombus aspiration are not available.

Hence this single center randomized open label trial is designed with specific aim to test the following hypothesis for STEMI patients with total occlusion undergoing primary PCI;

  • Whether use of export catheter reduces in-hospital and short term adverse events

  • Whether use of export reduces slow flow or no reflow

  • Whether use of export reduces the use of intracoronary drugs

  • Whether use of export within 6 hours of symptom onset significantly reduces in-hospital and short term adverse events

Consecutively recruited patients will be randomized to either primary PCI with export or primary PCI alone group in 2:1 ratio. Post aspiration immediate TIMI flow will be observed and all the patients will be observed for adverse outcomes (MACE) and complications including slow flow/no-reflow. Follow-up intervals will be at the end of one month of randomization and end of 6 month of randomization.

Study Design

Study Type:
Interventional
Anticipated Enrollment :
300 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
Manual thrombus aspiration (use of export catheter) followed by primary PCIManual thrombus aspiration (use of export catheter) followed by primary PCI
Masking:
Single (Outcomes Assessor)
Masking Description:
Blinded in-hospital outcomes assessment will be insured by separating patients recruitment and follow-up team and follow-up team will be kept blinded of randomization. All the patients will be assigned a unique identity code and collected data will be stored against the assigned code.
Primary Purpose:
Treatment
