Description
Victor Weerts and co-authors study a blood flow test for narrowed heart arteries in a 2026 paper. The test, called fractional flow reserve, judges whether a mid-level narrowing truly starves the heart of blood, and one cutoff is used for all arteries. The team asked whether that cutoff behaves the same in each of the heart's three main territories.
They reviewed three hundred ten patients tested on a single vessel at one center. Fewer than one in five narrowings tested positive, and positive results clustered in the front artery, with none in one side artery. Patients held back from surgery after a negative test did well over five years in every territory. The authors back the test for safe deferral, while urging vessel-aware reading.
