Figure 1 (A) Event-free (cardiac death or nonfatal myocardial infarction) survival of patients according to the response of the left ventricular (LV) end-systolic size to exercise. The one-, three- and five-year event-free survival rates for patients with a decrease in LV end-systolic size in response to exercise were 98.7 ± 0.3%, 95.8 ± 0.7% and 91.1 ± 1.3%, respectively (event rate 1.6%); and for patients with an increase or no change in LV end-systolic size, 98.0 ± 0.6%, 93.7± 1.3% and 86.2 ± 2.6%, respectively (event rate 2.9%). (B) The percentage of LV segments that were severely abnormal immediately after exercise. The one-, three- and five-year event-free survival rates for patients with 0% of LV segments severely abnormal immediately after exercise were 99.3 ± 0.3%, 96.6 ± 0.7% and 93.8 ± 1.3%, respectively (event rate 1.2%); for patients with 1% to 25% of LV segments severely abnormal, 97.7 ± 0.6%, 93.5 ± 1.2% and 91.3 ± 1.6%, respectively (event rate 2.2%); and for patients with >25% of LV segments severely abnormal, 97.8 ± 0.8%, 95.0 ± 1.4% and 75.2 ± 4.8%, respectively (event rate 3.8%).
