Clinical and MRI Cardiac Biomarkers on Peripheral Arterial Disease in Patients With Long Term DM (CMRPADDM)

April 6, 2017 updated by: Yu-Hsiang Juan, Chang Gung Memorial Hospital

The Evolution and Impact of Clinical and MRI Cardiac Biomarkers on Peripheral Arterial Disease in Patients With Long Term DM

The aim of this study is to establish a clinically feasible simultaneous evaluation of heart and lower limb using MRI and to assess the combined benefit of clinical and cardiac MRI imaging markers in the evaluation of PAD and prediction of treatment outcome.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

We expect to enroll about 60 long-term DM patients (>10 years) from main study. Patient will receive evaluation of the perfusion in the lower limb by using blood oxygenation-level dependent (BOLD) sequence with measurement of the extracellular volume fraction (ECV) as an indicator of fibrosis severity in calf muscles. All patients will receive cardiac MRI (cardiac function, ischemia and fibrosis) and MR angiography (severity of PAD). The baseline studies will be completed within 2 years and 3 additional follow-up studies will be performed by the end of 4th year.

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

All

Description

The inclusion criteria include:

  1. Able to understand and provide signed informed consent
  2. DM history of 10 years and above
  3. Willing to receive 3 MRI follow-up and serum hematocrit examinations within 2 years, if applicable
  4. Willing to receive standard therapy such as surgery or medication
  5. Age between 18-80 years old

The exclusion criteria include:

  1. Pregnant or breast-feeding women
  2. Allergic MRI contrast medium
