We sought to determine whether exercise-induced left bundle-branch block independently predicts mortality and cardiac morbidity. Using a matched control cohort study design, we compared 70 patients who developed this conduction disorder with 70 controls who did not. Kaplan-Meier event rates at 4 years were 19% among cases and 10% among controls. After adjusting for small differences in age, exercise-induced left bundle-branch block remained associated with a higher risk of developing a primary end point.
