Cardiac Catheterization, Coronary Computed Tomographic Angiography, Myocardial Infarction (MI)
Conditions
Brief summary
The goal of this clinical data collection study is to collect raw CT scan data using a new GSI Cardiac mode on GE HealthCare's Revolution Apex CT system. Two groups of participants will be enrolled: A) Participants scheduled to undergo a Coronary CT Angiography (CCTA) as part of their standard of care B) Participants scheduled to undergo a cardiac catheterization or have a history of heart attack Participants in Group A will: -Have a standard of care CCTA immediately followed by a research GSI Cardiac scan Participants in Group B will: -Have a research CCTA immediately followed by a research GSI Cardiac scan Both groups will be in the study for approximately 1 day. There are no follow-up visits after the day of scan.
Interventions
DEVICEGSI Cardiac Scan
The investigational GSI Cardiac scan will take place immediately ("back-to-back acquisition") following the single energy, non-GSI CCTA. The GSI Cardiac scan takes around 1 minute. A subset of Cohort B's participants who are eligible due to a history of heart attack will have the investigational GSI Cardiac scan 10-15 minutes after the end of the CCTA scan.
OTHERStandard of Care CCTA
The standard of care scan will be a single-energy, non-GSI CCTA. Any pre-contrast screening (such as kidney function or pregnancy testing) will follow the site's standard operating procedures. The administration of contrast media (either IV or oral) and any cardiac medications used to control heart rate will be prescribed per the site's standard operating procedures. All contrast and cardiac medications will be FDA approved and used in accordance with its approval.
OTHERResearch CCTA
The research scan will be a single-energy, non-GSI CCTA. Any pre-contrast screening (such as kidney function or pregnancy testing) will follow the site's standard operating procedures. The administration of contrast media (either IV or oral) and any cardiac medications used to control heart rate will be prescribed per the site's standard operating procedures. All contrast and cardiac medications will be FDA approved and used in accordance with its approval.
