Instead of catheter angiography, enzyme studies, and stress tests that can require a long stay in the ED, the immediate CT scan protocol can create a scenario where door-to-balloon time for ill patients can be 90 minutes, and the total time in the hospital for patients with negative results is reduced from an average 22 to 25 hours to a few hours. The doctors referenced are working on independent studies at major urban hospitals to show that using CT angiography at intake can rapidly, accurately, and cost-effectively identify which patients are at risk and need treatment and can allow the majority of patients to return home safely with low risk for a recurrent problem. Based on randomized large-scale trials, the physicians believe that CT scan in the ED allows for improved workflow, better treatment for cardiac patients at risk, and the ability to get detailed images of vessels and plaque in obese patients and patients who cannot be given beta-blockers to slow the heart down.
