What Is the Evidence That the Tissue Doppler Index E/e' Reflects Left Ventricular Filling Pressure Changes After Exercise or Pharmacological Intervention for Evaluating Diastolic Function? A Systematic Review.

ABSTRACT: Noninvasive echocardiographic tissue Doppler assessment (E/e') in response to exercise or pharmacological intervention has been proposed as a useful parameter to assess left ventricular (LV) filling pressure (LVFP) and LV diastolic dysfunction. However, the evidence for it is not well summarized. Clinical studies that evaluated invasive LVFP changes in response to exercise/other interventions and echocardiographic E/e' were identified from PubMed, Scopus, Embase, and Cochrane Library databases. We grouped and evaluated studies that included patients with preserved LV ejection fraction (LVEF), patients with mixed/reduced LVEF, and patients with specific cardiac conditions. Overall, we found 28 studies with 9 studies for preserved LVEF, which was our primary interest. Studies had differing m
