Evaluating ECG-less Cardiac CT for Diagnosing Coronary Artery Problems in Adults Surviving Cardiac Arrest Without STEMI

What this Trial Is About

Researchers are evaluating a new CT scan technique called ECG-less gated cardiac CT to see if it can accurately assess the coronary arteries in patients who survive a cardiac arrest without showing clear signs of a specific type of heart attack known as STEMI. This is important because current tests sometimes cannot clearly identify the cause of cardiac arrest, and the standard coronary angiography, while effective, is more invasive and carries some risks. The study aims to improve how doctors select patients who need urgent coronary angiography. The study uses an innovative CT scan method that does not require attaching ECG leads or extra medication, making it faster and safer in emergency settings. Patients undergo a combined pulmonary CT angiography and ECG-less cardiac scan using specialized equipment. This new technique captures images of the heart and blood vessels without additional contrast or drug administration, and the results will be compared to those from conventional coronary angiography. Participants are cardiac arrest survivors without STEMI who undergo the CT scan and then have a coronary angiography within 24 hours. Researchers will compare the two imaging results to measure how accurately the new CT technique identifies coronary artery disease. Additional follow-up evaluations include survival and heart function assessments up to 90 days after enrollment. The study involves various clinical measurements, monitoring, and safety evaluations throughout the process.
