PeriOperative Bridging - Perioperative Anticoagulation in the Setting of Recent Intracoronary Drug Eluting Stents
An observational study of Stent Thrombosis, run by The Cleveland Clinic at 1 site in United States.
Trial summary
The purpose of this study is to determine if an intravenous (IV) antiplatelet medication is as safe and effective at preventing clot formation in your stented artery as compared in people who have stopped clopidogrel prior to surgery. Read more about this study

About this study
Official title: Short-Term Outcomes of Perioperative Anticoagulation in the Setting of Recent Intracoronary Drug Eluting Stents
The purpose of this study is to determine if an intravenous (IV) antiplatelet medication is as safe and effective at preventing clot formation in your stented artery as compared in people who have stopped clopidogrel prior to surgery.
Read the detailed description
Stent thrombosis continues to be associated with a high rate of death or myocardial infarction. While this risk has been ameliorated through the use of the oral antiplatelet agent clopidogrel, there is a small but important subset of patients who will require discontinuation of clopidogrel due to unplanned or emergency surgery. These patients are exposed to a high risk of stent thrombosis during this time period. It is not known whether a strategy of intravenous antiplatelet therapy to "bridge" these patients is effective at preventing the morbidity related to stent thrombosis in the perioperative period. We intend to assess, in a prospective observational manner, the clinical course of patients who have undergone stent implantation less than 6 months prior to a surgical procedure requiring discontinuation of clopidogrel therapy and the efficacy of intravenous antiplatelet therapy to prevent morbidity related to stent thrombosis.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
stent thrombosis (time frame: hospitalization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
