New Diastology Guidelines: Evolution, Validation and Impact on Clinical Practice - 26/07/19
Résumé |
The 2016 American Society of Echocardiography/European Association of Echocardiography (ASE/EACVI) guidelines on the assessment of diastolic function sought to simplify the assessment of diastolic function by recommending a streamlined, stepped approach with a focus on four key variables. Haemodynamic validation using simultaneous cardiac catheterisation and echocardiographic assessment of diastolic function have shown robust prediction of left ventricular filling pressure (LVFP) using the streamlined 2016 algorithms, with favourable comparisons to the 2009 guidelines. Similarly, prognostic validation data demonstrates that the 2016 algorithms are easier to implement in clinical practice, have superior inter-observer reliability across a broad range of observer experience, and are better at predicting clinical outcomes. Furthermore, published data show improved classification of clinical heart failure patients. However, increased specificity of the updated 2016 guidelines results in a lower prevalence of diastolic dysfunction compared to the 2009 recommendations. Further refinement of guidelines for the identification and diagnosis of diastolic dysfunction is possible through incorporation of new diastolic parameters.
