Infrasensor for Early Identification of High-grade Obstructive Non-ST-segment Elevation Acute Coronary Syndrome in Patients With Suspected Acute Coronary Syndrome
The objective of this prospective, cross-sectional, multicenter pivotal trial study is to validate Infrasensor's clinical performance for the detection of high grade obstructive NSTE-ACS. High-grade obstructive NSTE-ACS is defined as an acute coronary syndrome in which severe obstructive coronary artery disease, including total coronary artery occlusion is present. Study Endpoints Primary Endpoint: Infrasensor performance (Lower bound of 95% CI for sensitivity, specificity) between device detection of high-grade obstructive NSTE-ACS and angiographic diagnosis of High-grade obstructive CAD defined as the aggregate of \>50% left main stenosis, or \>70% stenosis in 1 or more coronary arteries and/or emergent revascularization. Secondary Endpoint: Infrasensor performance (positive and negative predictive values, and overall accuracy).
• Subject is willing and able to sign an Informed Consent
• Age: ≥18 years
• Study subjects with symptoms suggestive of ACS within 24 hours of presentation in an emergency department or acute care setting in whom invasive coronary angiography is intended.
• The following conditions for Infrasensor use must be present: The Infrasensor should only be used on alert patients who are able to keep the device still for the 5 minute measurement duration, who have clean, intact skin at the measurement site, and who do not have blood pressure cuffs, IV lines, or other medical equipment on the arm used for measurement.
