China-based Rainmed Medical Limited has announced that it has received market approval from the National Medical Products Administration (NMPA) for its innovative coronary artery function measurement system, the caIMR system.
Microcirculatory Resistance Index (IMR) and Its Clinical Significance
The microcirculatory resistance index (IMR) is a quantitative method used to evaluate the microvascular function of blood vessels. It is crucial for identifying effective adjuvant treatments to reduce microcirculation dysfunction and improve patient prognosis following percutaneous coronary intervention (PCI). IMR guides the diagnosis and management of patients with coronary artery disease (CAD). Approximately 70% of patients undergoing coronary angiography have microvascular dysfunction and require IMR measurement. However, accurate IMR measurement has traditionally required interventional surgery, which is complex, time-consuming, and inconvenient for clinical use.
The caIMR System: A Breakthrough in Intervention Precision Medicine
The caIMR system is a groundbreaking product in the field of intervention precision medicine, designed to address microcirculation disorders. In confirmatory clinical trials, the system demonstrated an evaluation accuracy of up to 93.8%. Compared to the traditional guide wire-based IMR measurement, which takes 40 to 60 minutes, the caIMR system significantly reduces the time required for IMR measurement and coronary microvascular disease diagnosis to an average of fewer than five minutes.-Fineline Info & Tech
