Validation of novel biomarkers to assess cardiac diastolic function extracted using a high frame rate speckle tracking algorithm

Accurate assessment of diastolic function is essential not only for diagnostic purposes, but also for estimates on prognosis. Several studies have shown the correlation of novel diastolic biomarkers, i.e., Strain Rate (SR) during isovolumic relaxation (SRIVR) and early filling (SRe), with the invasive gold standard assessment of left ventricular (LV) diastolic function, thus ...
