contrast fluid via an IV, and usually a 64-slice scanner creates a detailed three-dimensional image of the beating heart that a doctor can examine for evidence of fatty or calcium deposits. This test is less invasive and less expensive, but somewhat less accurate, than the standard angiogram....
There would also be false-positive results in that many calcified arteries will have normal blood flow and will not be affected by clinically apparent thrombosis: abnormal CT not followed by a heart attack." The NCCHTA assessment concluded: "For CT screening to be cost-effective, it has to a...
"There was no difference incardiac eventsat 90 days or at 18 months between the group that had positive findings on the CT angiogram screening compared to the group that did not have the test," says John W. McEvoy, M.B., BCh., BAO, a Johns Hopkins heart specialist and lead author of...
Cardiovascular diseases are still among the first causes of death worldwide with a huge impact on healthcare systems. Within these conditions, the correct diagnosis of coronary artery disease with the most appropriate imaging-based evaluations is of utmost importance. The sustainability of the healthca...
FFRCT led to a change in hypothetical management in 65% (64/98; p<0.001) patients with a functional imaging test cancelled in 17% (17/98) and a diagnostic angiogram cancelled in 47% (46/98). FFRCT-guided management had a reduced mean time to definitive investigation compared with CTCA ...

particularly myocardial infarction (MI) (10), and a recent 2018 paradigm-shifting New England Journal of Medicine publication showed 5-year hard outcomes that were clearly in favor of coronary CTA, with less invasive angiograms compared with standard of care after the 12-month follow-up point (...
