Irrelevant: Lexiscan is an effective agent for stress tests which is independent of heart rate. It doesn't matter what your heart rate was.

Max predicted HR...: Exercise stress testing requires that the patient reach 85% of maximum predicted heart rate. Maximum predicted heart rate is given by equation (220-age). If adequate heart rate is not achieved then pharmacologic (lexiscan) stress test can be performed.
