Implication
May refine risk stratification on exercise echocardiography; hypothesis-generating and requires prospective validation before practice change.
Structured PICO
Does elevated exercise E/e' predict cardiovascular death and hospitalization in patients referred for exercise echocardiography?
P
Population
522 patients referred for exercise echocardiography
I
Intervention
Measurement of exercise E/e' (ratio of transmitral and annular velocities) to estimate left ventricular filling pressure during exercise echocardiography
C
Comparator
Normal exercise E/e' and absence of inducible ischemia
O
Outcome
Composite of cardiovascular death and hospitalizationcomposite
Exercise E/e' provides incremental prognostic value beyond exercise capacity and inducible ischemia for predicting cardiovascular events in patients undergoing exercise echocardiography.
