Application of the 2016 ASE-EACVI Criteria for the Assessment of Diastolic Function in Arterial Hypertension

Introduction: No data are available on the diagnostic algorithms recommended by guidelines for the assessment of diastolic dysfunction (DD) in patients with arterial hypertension. Aim: To fill this gap, we evaluated diastolic function in hypertensive patients with and without LVH matched with healthy subjects by applying 2016 American Society of Echocardiography-European Association of Cardiovascular Imaging Guidelines for the evaluation of LV diastolic function. Methods: 717 healthy and hypertensives with normal LV ejection fraction and with and without LV hypertrophy (LVH), matched 1:1:1 from two prospective registries, represented the study population. Results: By applying algorithm A, indeterminate pattern was found in 0.4% of healthy, in 6.3% of hypertensives without LVH, and in 21% with LVH (overall p < 0.05 vs. healthy). DD was absent in healthy, however present in 2 and 8% of hypertensives without and with LVH (p = 0.06 and p = 0.001 vs. healthy, respectively). By applying algorithm B, no cases of indeterminate pattern were found. DD was observed in 2.9% of healthy, 7 and 10.5% of hypertensives without and with LVH (p < 0.05 vs. healthy). Conclusions: The use of algorithm A should be limited only to truly normal subjects, whereas algorithm B should be applied to all patients with hypertension, even without comorbidities and irrespective of LVH.
