Prognostic value of peak work rate indexed by left ventricular diameter.

ABSTRACT: Left ventricular diameter (LVEDD) increases with systematic endurance training but also in various cardiac diseases. High exercise capacity associates with favorable outcomes. We hypothesized that peak work rate (W_peak) indexed to LVEDD would carry prognostic information and aimed to evaluate the association between W_peak/LVEDD_rest and cardiovascular mortality. W_peak/LVEDD_rest (W/mm) was calculated in patients with an echocardiographic examination within 3 months of a maximal cycle ergometer exercise test. Low W_peak/LVEDD_rest was defined as a value below the sex- and age-specific 5th percentile among lower-risk subjects. The association with cardiovascular mortality was evaluated using Cox regression. In total, 30
