NCT02077218

Brief Summary

This pilot clinical trial studies computed tomography (CT) scans and biomarker analysis in diagnosing coronary artery disease (CAD) in patients who have undergone a stem cell transplant but have no symptoms of CAD. CAD is a disease in which there is a narrowing or blockage of the coronary arteries (blood vessels that carry blood and oxygen to the heart) and patients who have undergone a stem cell transplant are at an especially high risk for CAD. A CT scan involves a series of detailed pictures of areas inside the body taken from different angles. The pictures are created by a computer linked to an x-ray machine. Studying samples of blood from patients who have undergone a stem cell transplant in the laboratory may help doctors identify and learn more about biomarkers related to CAD. Using a CT scan in combination with biomarker analysis may be a better and less-invasive way to diagnose CAD.

Outcome Measures

Primary Outcomes (1)

  • Feasibility, defined by the percentage of patients that enroll onto the study, successful completion of all study measurements, ability of studies to be interpreted, and achievement of the recruitment goal

    The current protocol will be considered feasible if: 1) \>= 30% of eligible patients that are approached for participation enroll onto the study, 2) \>= 75% enrolled participants successfully complete all study measurements (history/physical examination, blood draw, completion of study questionnaires, CT-imaging), 3) \>= 90% of CT-based studies can be interpreted and 4) =\< 100 individuals are approached to achieve recruitment goal of 20 participants.

    Up to 9 weeks

Other Outcomes (9)

  • Prevalence of asymptomatic CAD, as measured by CT angiography

    Up to 9 weeks

  • Severity of asymptomatic CAD, as measured by CT angiography

    Up to 9 weeks

  • Patient demographics (age, sex, race/ethnicity)

    Up to 9 weeks

  • +6 more other outcomes
