Impaired coronary flow reserve flags poor prognosis: review

Coronary flow measurement should be more routinely used to stratify risk, researchers say

Older adults with an abnormal coronary flow reserve have a near four-fold higher risk of all-cause death compared with those with normal coronary flow, a systematic review has found.

And every 0.1-unit reduction in coronary flow reserve (CFR) upped the likelihood of mortality and major adverse cardiovascular events (MACE), the UK researchers say.
