Discussion
To the best of our knowledge, the present study is the first to assess
the feasibility and test-retest reproducibility of all major
measurements of left ventricular diastolic function included in the
former and current guidelines. The findings, acquired from patients
commonly encountered, are in accordance with a true clinical scenario
and thus mirror daily clinical practice. Comparing the recent guidelines
from 2016 with the more ambiguous guidelines from 2009, it was exposed
that the classification of diastolic function in the guidelines from
2016 was superior in terms of both feasibility and reproducibility.
