SYSTEMS AND METHODS FOR DETERMINING CORONARY FLOW RESERVE

摘要

The invention generally relates to systems and methods for determining coronary flow reserve (CFR). The invention provides systems and methods for determining coronary flow reserve using a flow reserve index obtained at rest and during hyperemia. One flow reserve index obtained under the two conditions can be used to compute coronary flow reserve. The difference between the resting value and the hyperemic value of the index correlates to a coronary flow reserve value.

主权项

1. A method of determining coronary flow reserve, the method comprising:
obtaining a resting value for a flow reserve index from a patient; obtaining a hyperemic value for the flow reserve index from the patient; computing the coronary flow reserve based on the resting value and the hyperemic value; and providing the coronary flow reserve to a user.
