Why the study?
Is the E/E' ratio more sensitive than the E/A ratio for detecting left ventricular diastolic dysfunction in patients with systemic lupus erythematosus?
Is the E/E' ratio more sensitive than the E/A ratio for detecting left ventricular diastolic dysfunction in patients with systemic lupus erythematosus?
The E/E' ratio is a more sensitive echocardiographic marker than the E/A ratio for detecting subclinical left ventricular diastolic dysfunction in patients with systemic lupus erythematosus.

E/E' may detect subclinical LV diastolic dysfunction missed by E/A in SLE; hypothesis-generating and should not change practice without prospective validation.
Park et al. (2008) studied this question.
