Coronary flow reserve provides independent prognostic information in diabetic and nondiabetic patients with known or suspected coronary artery disease and negative dipyridamole stress echocardiography. In particular, a normal CFR off therapy is associated with better and similar survival in the 2 populations.

In DCM patients, CFR is often impaired. A reduced CFR during vasodilator stress is an independent prognostic marker of bad prognosis.

CFR on LAD is a strong and independent indicator of mortality, conferring additional prognostic value over wall motion analysis in patients with known or suspected CAD. A negative result on stress echocardiography with a normal CFR confers an annual risk of death <1% in both patient groups.

In patients with known or suspected CAD, DET result by wall motion criteria and CFR are additive and complementary for the identification of patients at risk of experiencing hard events.

CFR on LAD provides useful information for vessel stenosis and prognostic assessment in both hypertensive and normotensive patients. However, diagnostic specificity is reduced in hypertensive.
