High-Sensitivity Cardiac Troponin Assays in U.S. Hospitals

“The implementation of high-sensitivity troponin [assays] increased steadily, but at the end of our study period, just one-third of hospitals had implemented the assays. The study period ended in September 2021 because we didn't have data beyond that period, and the new chest pain guidelines were introduced in October 2021, so it's possible uptake will increase more dramatically. But we'll have to wait and see.”

“We examined the implementation of high-sensitivity cardiac troponin assays among participating hospitals in the National Cardiovascular Data Registry Chest Pain-MI Registry in the United States. We found that, although implementation is increasing, only one-third of hospitals had implemented these assays by the third quarter of 2021. We found use of high-sensitivity cardiac troponin was associated with a slightly shorter length of hospital stay, more use of echocardiography for non-ST segment elevation ACS and less use of invasive angiography in low-risk chest pain patients.”
