Newly published data shows using a Respiratory Modulation Response (RMR) is a novel, non-invasive measure to quickly and accurately detect the presence of significant coronary artery disease (sCAD). Patients in the study with sCAD had a lower RMR compared to patients without, regardless of their risk factors or clinical history of angina, previous myocardial infarction (MI), or angioplasty. These data, published in the current issue of Euro Intervention Journal, demonstrate that RMR was lower in patients with significant CAD compared to those with non-significant CAD (P<0.0011), regardless of their risk factors or clinical history of angina, previous MI, or angioplasty.
Researchers at Rabin Medical Center used an innovative respiratory stress test developed by SPIROCORTM Ltd. The test uses a Pulse Oximeter (PPG) to measure a patient's blood flow in the finger in response to his or her paced breathing for 70 seconds. PPG data captured in the study are recorded immediately and analyzed using a proprietary algorithm that determines the Respiratory Modulation Response in a percent value. The findings of this study were further validated in research recently published in Cardiovascular Revascularization Medicine.
"Identifying significant coronary artery disease through non-invasive testing is very challenging," said Dr. Ran Kornowski, Director, Interventional Cardiology, Rabin Medical Center, Tel Aviv. "This study shows that the SPIROCOR test is a simple and non-invasive test that independently predicts significant coronary artery disease in patients referred for a coronary artery evaluation."
