Um índice de função sisto-diastólica muito bom!

Left ventricular dysfunction measured by TDI is a powerful and independent predictor of death in the general population. When the information on systolic and diastolic performance provided by TDI is combined, the prognostic value of TDI is further strengthened.

Combined index (eas index) of diastolic and systolic performance: e'/(a'xs')
