ABSTRACT


OBJECTIVES - The aim of this study was to evaluate the utility of distal protection during percutaneous coronary intervention (PCI) in patients with acute coronary syndromes at high risk for distal embolization.


BACKGROUND - The results of previous clinical trials indicated that the routine use of distal protection in patients with ST-segment elevation myocardial infarction did not improve clinical outcomes. However, selective use of distal protection by means of a filter-based distal protection system has not been evaluated.

METHODS - Two hundred patients with acute coronary syndromes who had native coronary artery lesions and attenuated plaque with longitudinal length ≥5 mm on pre-PCI intravascular ultrasound were randomly assigned to undergo PCI with distal protection or conventional treatment.

RESULTS - The primary endpoint (no-reflow phenomenon) occurred in 26 patients (26.5%) in the distal protection group and 39 patients (41.7%) in the conventional treatment group (p = 0.026), and the corrected TIMI (Thrombolysis In Myocardial Infarction) frame count after revascularization was significantly lower in the distal protection group (23 vs. 30.5; p = 0.0003). The incidence of cardiac death, cardiac arrest, cardiogenic shock after revascularization requiring defibrillation, cardiopulmonary resuscitation, or extracorporeal membrane oxygenation was significantly lower in the distal protection group than in the conventional treatment group (0% vs. 5.2%; p = 0.028).

CONCLUSIONS - The use of distal embolic protection applied with a filter device decreased the incidence of the no-reflow phenomenon and was associated with fewer serious adverse cardiac events after revascularization than conventional PCI in patients with acute coronary syndromes with attenuated plaque ≥5 mm in length.
