Coronary Artery Disease Clinical Trial
Official title:
Comprehensive Characterization of Coronary Atherosclerotic Disease Using Photon Counting- Detector Dual-source CT and Its Impact on Patient Management
Verified date | November 2023 |

Is FDA regulated | No |
Health authority | |
Study type | Interventional |
The purpose of this research trial is to determine whether images taken using a Photon Counting Detector CT scanner (PCD-CT) after the patient has received a drug that makes the heart work harder provide clinically important information about the severity of suspected coronary artery disease compared to CT imaging performed without using the drug that causes the heart to work harder.

Eligibility | Inclusion Criteria: - Patients referred for coronary artery cardiac CT imaging or nuclear medicine or MRI cardiac perfusion within the Department of Radiology or Cardiology. - Patients who are able and willing to sign the informed consent will be enrolled - Negative pregnancy test if subject is of child-bearing age (females of child-bearing potential will be screened for pregnancy using a urine pregnancy test, which will be administered by the unit study coordinator at no cost to the patient). Exclusion Criteria: - Patients unable to provide written informed consent - Pregnancy - eGFR = 30 - History of prior moderate or severe contrast reaction includes: unresponsiveness, severe respiratory distress, convulsions, arrhythmia, cardiopulmonary distress, progressive angioedema, laryngeal edema, dyspnea, bronchospasm, symptomatic tachycardia, symptomatic bradycardia, hypotension, hypertensive crisis. - Any history of required premedication prior to iodinated contrast administration. - Patients that consent to participation but do not undergo their clinically-indicated, contrast-enhanced CT, or nuclear medicine or MR perfusion scanning for any reason (e.g., bad IV, infiltration, reaction, change in indication). - Patients experiencing atrial fibrillation, premature ventricular contractions or other heart rhythm abnormalities - Hospitalized patients or patients under care in the Emergency Department Specific exclusion criteria only for participation in the cardiac stress test arm of this study (requiring administration of Regadenoson): - Anything by mouth within three hours of the examination - Known hypersensitivity to Regadenoson, Adenosine, or Dipyridamole. - Active ongoing wheezing or poorly controlled asthma or COPD (hospitalized within last month or receiving treatment for flair within last month). - Second (type I or II) or third degree atrioventricular (AV) block or sinus node dysfunction unless patient has functioning artificial pacemaker. - Ingested greater than 4 oz. of caffeine within the last 12 hours. - Currently experiencing unstable coronary syndrome. - Uncontrollable seizures within the last 3 months |

Primary | Change in disease status or post-exam recommendations | A sub-specialty trained cardiac radiologist and a sub-specialty trained cardiologist will compare qualitative and quantitative results from the photon counting CT scans to the clinically ordered CT, MRI, or nuclear medicine scan. Clinically important differences in findings and recommendations will be recorded to assess the overall clinical impact of using photon-counting CT to assess patients with potential coronary artery disease, especially patients with heavily calcified, stented, or high-risk plaques, or having myocardial perfusion defects. Our premise is that the established benefits of PCD-CT, used with a dual-source geometry and advanced noise reduction and material decomposition algorithms, will yield clinically important differences in imaging findings that will impact patient management decisions. | Through completion of CT exam, approximately 1 day |
