UNASSIGNED: Objective Interpretation of the electrocardiogram (ECG) during exercise is not easy in @entity1 with @entity714 ( @entity714 ). Also, the value of exercise echocardiography (ExE) for predicting outcome in them has not been addressed. We sought to assess its prognostic value in @entity1 with @entity714 and known/suspected @entity301 . Design Retrospective analysis of data on 703 @entity1 with @entity714 who were submitted to a clinically-indicated ExE. The end points were overall mortality and combined @entity583 and @entity65 . Results During follow-up (4.1        4.5 years) there were 130 deaths and 108 combined events. Independent predictors of combined events were history of @entity453 (hazard ratio [HR]   =   2.37, 95% Confidence Interval [CI]   =   1.24-4.52, p   =   0.009) resting wall motion score index (HR   =   2.14, 95% CI   =   1.12-4.10, p   =   0.02), metabolic equivalents (HR   =   0.89, 95% CI   =   0.93-0.97, p   =   0.007),    in double product with exercise (HR   =   0.96, 95% CI   =   0.92-1.00, p   =   0.036) and    in left ventricular ejection fraction (LVEF) with exercise (HR   =   0.97, 95% CI   =   0.94-0.99, p   =   0.01). Neither positive clinical nor ECG exercise testing was predictive. Combined event rates were 3.3% in @entity1 with   LVEF   >   5%, 4.7% in those with   LVEF between 1-5% and 8.2% in those with no increase (     <   1%). Conclusions A decrease in LVEF during exercise is predictive of serious events in @entity1 with @entity714 .
