Hyperventilation Strain CMR Imaging in Patients With Acute Chest Pain

MORRISVILLE, N.C., August 9, 2022 – MyoStress™, a rapid stress test utilizing breathing maneuvers, has continued to demonstrate excellent accuracy at detecting ischemic coronary artery disease without the need for pharmacologic stress agents or contrast injections in this new publication from University of Heidelberg.

In this article, results comparing MyoStress to high sensitivity troponin and EKG in triaging patients with chest pain in the emergency department reiterated the clinical utility of MyoStress. In detecting ischemia, MyoStress was highly accurate (95.4%) and provided improved benefit over traditional emergency room chest pain protocols. MyoStress has the potential to help reduce crowding in the emergency department by accelerating diagnostic work up in coordination with traditional emergency room chest pain protocols for suspected acute coronary syndrome (ACS).

Conclusion: “Our suggested protocol achieved a high diagnostic accuracy, outperforming other clinical markers for ACS identification. This approach may be particularly useful for ‘troponin observe zone’ patients allowing for a safe, drug-free, and non-invasive assessment of myocardial function.”
