CORE-COMPARE Pilot Study

Description

The utility of Ultra High-Resolution Computed Tomography (UHR-CT) compared to conventional CT in all-comers (i.e., a generally lower-risk population) remains uncertain but is an important area of study in order to justify wider spread implementation and use of this technology, particularly in light of reports of significantly higher radiation exposure with UHR-CT, as well as longer scan times. The availability of technology to reconstruct conventional resolution (CR) simulation images from the raw CT acquisition data acquired on the UHR-CT scanner offers a unique platform to study this question without subjecting individuals to two different scans. The primary objective of this study is to generate preliminary data in support of the hypothesis that noninvasive UHR-CT is superior to conventional resolution CT for identifying patients with obstructive CHD.

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Patients aged 21-85 years
  • * Clinical history suggestive of CHD who are referred by their primary cardiologist for further evaluation via Computed tomography angiography (CTA) will be asked to participate.
  • * Women of child bearing potential must demonstrate a negative pregnancy test within 24 hours of the study CTA.
  • * Ability to understand and willingness to sign the Informed Consent Form.
  • * Known allergy to iodinated contrast media.
  • * History of multiple myeloma or previous organ transplantation
  • * Elevated serum creatinine (\> 1.5mg/dl) OR calculated creatinine clearance of \< 60 ml/min (using the Cockcroft-Gault formula
  • * Atrial fibrillation or uncontrolled tachyarrhythmia, or advanced atrioventricular block (second or third degree heart block)
  • * Evidence of severe symptomatic heart failure (NYHA Class III or IV);
  • * Known or suspected moderate or severe aortic stenosis
  • * History of prior percutaneous coronary intervention (PCI) in one or more vessel or history of coronary arterial bypass grafting (CABG)
  • * Suspected acute coronary syndrome
  • * Presence of any other history or condition that the investigator feels would be problematic
