Understanding heart imaging scans to predict heart disease risk

Researchers are studying a special heart imaging scan called CT coronary angiography to see how well it can detect heart disease and predict who is at risk for serious heart problems. This study is collecting information from patients who have already had this scan over the past 4 years to learn whether the scan results can better predict which patients will have heart attacks, unstable angina, or other dangerous heart events.

Doctors need better ways to figure out which patients with suspected heart disease are actually at high risk for serious problems. This study aims to show how reliable and useful this imaging scan is for identifying the true burden of heart disease and predicting future cardiovascular events.
