Leveraging Speed & Accuracy to Enable the First Ever Green & "Needle-free" Stress Test

A peer-reviewed study published in the Journal of the American College of Cardiology: Cardiovascular Imaging validated MyoStress for its ability to accurately detect myocardial ischemia using a hyperventilation breath-hold maneuver, providing a faster and safer stress test to help improve the diagnosis and management of coronary artery disease.

CMR detects decreased myocardial deformation in asymptomatic patients at risk for heart failure
A recently published article from Berlin highlights the potential of MyoStress in terms of identifying at-risk patients who have reserve and are therefore not symptomatic compared to patients with heart failure who have a preserved ejection fraction. This article shows that asymptomatic subjects with increased CV risk present with HFpEF like impaired myocardial deformation at rest, while they show results like controls under HG stress.

Fast-Strain Encoded Cardiac Magnetic Resonance During Vasodilator Perfusion Stress Testing
This study shows MyoStress was non-inferior to CMR stress testing, with a comparable ability to diagnose and risk stratify CAD patients. This test offers advantages in speed, ease and reproducibility, creating an opportunity for a rapid, cost-effective stress test that gives physicians the ability to evaluate patients efficiently.

Feasibility of fast cardiovascular magnetic resonance strain imaging in patients presenting with acute chest pain
This study indicates that in patients presenting with acute chest pain and inconclusive initial clinical screening, MyoStrain can be used to rule out obstructive coronary artery disease. These results show that MyoStrain may serve as a fast and accurate diagnostic tool that could be integrated into clinical workflows.
