Detection of Left Ventricular Diastolic Dysfunction Grade Ii-Iii by New Dopplerographic Ratio E/El

Abstract

relationship between EL and cardiac structure and function in patients with HFmrEF. Methods: The study includes 28 patients with HFmrEF, compared with 23 normals. HFmrEF patients are divided into 2 groups:group I with diastolic dysfunction, group II without diastolic dysfunction. VFM is used to calculate EL in left ventricle in IVR, RFP, ACP, IVC, REP. Results: The EL at RFP, IVC, REP in left ventricle at every phase decrease in the HFmrEF group. Compared with group II,the EL of group I at IVR and RFP increase (P,0.05).The EL at RFP, IVC, REP in left ventricle decrease in the HFmrEF group (P,0.05). Compared with group II,the EL of group I at IVR and RFP increase (P,0.05). Total EL in LV during RFP is independently associated with E/e' (b5 0.423, P5 0.019).Total EL in LV during ACP is associated with GLS(b5 0.392, P5 0.039).Total EL in LV during IVC is independently associated with GLS (b5 0.546, P5 0.001). Conclusions: In HEmrEF, EL in the left ventricle decreases in RFP, IVC, REP. However, the EL in RFP will increase if accompanied with diastolic dysfunction. The EL in the left ventricle in RFP is related to the diastolic function of the heart, and the EL in ACP and IVC is related to the systolic function of the heart.
