Trial Outcomes & Findings for Optical Frequency Domain Imaging (OFDI) and Vascular Healing After Stent Placement (NCT NCT01794949)

NCT ID: NCT01794949

Last Updated: 2017-05-15

Results Overview

Assessment of vascular healing 6 months after Resolute Integrity placement in non-diabetic patients and patients with non-insulin dependent diabetes presenting with acute coronary syndrome (ACS) using optical frequency domain imaging (OFDI). Vascular healing will be measured by percent covered stents as determined by OFDI. A higher percentage of stent coverage indicates increased endothelial regrowth, which is an essential component for the maintenance of long-term luminal patency.

Participant Flow

Participants were selected from patients with acute coronary syndrome (ACS) presenting to Emory University Hospital Midtown for coronary angiography. Participants were recruited between September 2013 and September 2015.

Of the 24 individuals who signed the consent form, 16 were found to be ineligible to participate in the study, resulting in 8 participants who started the trial.

PRIMARY outcome

Timeframe: 6 months

Population: Participants included in the analyses for this outcome are those who completed the 6 month follow-up imaging to assess vascular healing. Optical frequency domain imaging (OFDI) was not performed on two participants in the non-diabetic study arm.

Assessment of vascular healing 6 months after Resolute Integrity placement in non-diabetic patients and patients with non-insulin dependent diabetes presenting with acute coronary syndrome (ACS) using optical frequency domain imaging (OFDI). Vascular healing will be measured by percent covered stents as determined by OFDI. A higher percentage of stent coverage indicates increased endothelial regrowth, which is an essential component for the maintenance of long-term luminal patency.
