Zotarolimus vs Sirolimus Eluting Stent in High Bleeding Risk

Instituto Nacional de Cardiologia Ignacio Chavez280 enrolled

Overview

Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients who underwent elective coronary percutaneous intervention with a zotarolimus eluting stent versus a sirolimus eluting stent and short Dual Antiplatelet Therapy (DAPT).

Interventions

Zotarolimus eluting stentDEVICE

Size (diameter and length) will be chosen at operator's discretion aided by simple angiography, QCA, or intravascular image; so that the lesion previously prepared and 2 mm at each end are covered by DES with an stent to artery ratio of 1.1. Post-dilatation will be performed when indicated. Device will be used by CE mark instructions. All patients will receive DAPT as follows: After a loading dose (if necessary) of aspirin and a P2Y12 inhibitor, aspirin 100 mg and a P2Y12 inhibitor daily will be indicated for 1 month in both ACS and Chronic Coronary Syndrome (CCS). Patients with high ischemic risk could be extended to 3 months. After DAPT, SAPT will be continued with the drug of choice, preferably P2Y12 inhibitor. Patients requiring chronic anticoagulation will receive triple therapy only during hospitalization. At release, an oral anticoagulant (NOAC preferred over VKA) will be indicated along with 6 months of SAPT with a P2Y12 inhibitor.

Outcomes

Primary Outcomes

Target Lesion Failure (TLF)

Rate of composed of cardiovascular death, myocardial infarction related to the treated vessel or ischemia driven target lesion revascularization

Time frame: 12 months

Secondary Outcomes

Cardiovascular death

Rate of death resulting from cardiovascular causes: Death caused by acute MI Death caused by sudden cardiac, including unwitnessed, death Death resulting from heart failure Death caused by stroke Death caused by cardiovascular procedures Death resulting from cardiovascular hemorrhage Death resulting from other cardiovascular cause Any MI not clearly attributable to a non- target vessel will be considered as target-vessel MI. Percutaneous coronary intervention (PCI) related MI is termed type 4a MI.

Time frame: 12 months

Myocardial Infarction related to the treated vessel

Rate of myocardial infarction related to the treated vessel (according to the 4th international definition of myocardial infarction): detection of an increase or decrease in cardiac troponin values with at least 1 of the values above the upper reference limit of the 99th percentile and at least 1 of the following conditions : Symptoms of acute myocardial ischemia. New ischemic changes in the electrocardiogram. Appearance of pathological Q waves. Imaging evidence of loss of viable myocardium or new regional abnormalities in myocardial wall mobility following a pattern compatible with ischemic etiology. Identification of a coronary thrombus by angiography with intracoronary imaging or by autopsy Any MI that cannot be clearly attributed to a vessel other than the revascularized one will be considered as MI related to the treated vessel.

Time frame: 12 months

Target Lesion Revascularization

Rate of repeated percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion.

Time frame: 12 months
