Vascular Healing After Deployment of Titanium-nitride-oxide-coated OPTIMAX™ Stent and PROMUS-ELEMENT™ Everolimus-Eluting Stent (TIDES-OCT)

October 30, 2014 updated by: The Hospital District of Satakunta

A Randomized Prospective Multicenter Trial to Compare Vascular Healing and Vasodilation at 2 Months After Deployment of TItanium-nitride-oxide-coated OPTIMAX™ Stent and PROMUS-ELEMENT™ Drug-Eluting Stent in Patients With Acute Coronary Syndromes by Means of Optical Coherence Tomography and Coronary Flow Reserve

The purpose of this study is to compare vascular healing of the stented segment after deployment of titanium-nitride-oxide coated cobalt-chromium Optimax™-stent stent and Promus-Element™ everolimus-eluting stent in patients with acute coronary syndromes requiring percutaneous coronary intervention.

  1. Comparison of OCT and CFR findings of titanium-nitride-oxide coated cobalt-chromium Optimax™-stent and Promus-Element™ everolimus-eluting stent at two months after the index procedure.
  2. Comparison of intravascular coronary flow reserve measurement to non-invasive transthoracic echocardiography-derived coronary flow reserve measurement.
  3. Comparison of epicardial vasodilation to coronary microcirculatory vasodilation

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Percentage of uncovered struts
Time Frame: 2 months
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
