Prognostic value of heart rate reserve is additive to coronary flow velocity reserve during dipyridamole stress echocardiography.

CONCLUSIONS: HRR is weakly related to CFVR, and a blunted HRR usefully complements RWMA and CFVR for prediction of outcome with dipyridamole SE. The patient without inducible RWMA is still at intermediate risk, but the risk is low with concomitant preserved CFVR, and very low with concomitant normal HRR.
