Researchers may have discovered an effective method of predicting heart attack and other serious cardiovascular events with a combination of CT angiography and CT myocardial stress perfusion imaging.
The research, published in the journal Radiology, found that the CT imaging combinations could work just as well or better than invasive coronary angiography and stress tests with single photon emission tomography (SPECT) in predicting adverse cardiovascular events.
"Invasive angiography is generally safe, but it can cause vascular problems in a significant number of patients, most commonly at the site of the puncture," said João A.C. Lima, MD, the lead author on the study, who works at Johns Hopkins Hospital and School of Medicine in Baltimore. "In rare cases, it can cause strokes or heart attacks. These risks are not trivial."
