This study evaluates the clinical usefulness of ST/HR slope derived from ST elevation on exercise to predict the improvement in regional wall motion following coronary revascularization in patients with healed myocardial infarction. We studied 58 patients with a diseased, infarct-related and single-vessel coronary artery. The decline calculated from the final 12 data points relating ST-segment elevation to heart rate during exercise were derived (ST/HR slope). Hypokinesis in the infarcted region was assessed by the centerline method and expressed in terms of standard deviations (SD/chord). The increase more than 30% of the SD/chord, which was defined as the improvement in regional wall motion, was seen in 23 of the 30 patients with a ST/HR slope of > or = 5.0 (microV/bpm), and in 4 of the 28 patients with a ST/HR slope <5.0 (microV/bpm) (P <.0001). Thus, a ST/HR slope derived from ST elevation on exercise identifies subgroups of patients who show a good recovery of regional wall motion.
