Table 2 Clinical applications of tissue Doppler and strain

From: Tissue Doppler and strain imaging: anything left in the echo-lab?

Parameters Information Clinical condition TDI Strain SR
Basal systolic peak Global longitudinal systolic function Aspecific - - +/-
Systolic time-to-peak Mechanical dyssynchronicity Cardiomyopathy + +/- -
Systolic peak Right ventricular systolic function Heart failure - +/- +/-
Systolic peak and/or protodiastolic peak Regional systolic function at rest Ischemic Cardiopathy - +/- +/-
Systolic peak and/or protodiastolic peak Regional systolic function during stress Ischemic Cardiopathy - +/- +/-
Systolic peak Preclinical cardiac involvement Infiltrative Cardiomyopathy - - +/-
Systolic peak Monitoring of therapeutic effect Infiltrative Cardiomyopathy - +/- +/-
Protodiastolic peak Ventricular filling pressures Aspecific ++ - +/-
Protodiastolic peak Prognostic indicator Arterial Hypertension + - -
Protodiastolic peak Distinction between constriction and restriction Heart failure + - +/-
Protodiastolic peak Identification of pathological hypertrophy Ventricular Hypertrophy + - +/-
Atrial systolic peak Prediction of response to cardioversion Atrial Fibrillation - + -
  1. SR = Strain rate; - = not useful; +/- = useful but limited reproducibility; + = potentially useful; ++ = proven to be useful.
