Data are expressed as mean ± SD. A, late diastolic transmitral velocity; A’, late diastolic myocardial velocity; E, early diastolic transmitral velocity; E’, early diastolic myocardial velocity; DT, deceleration time; IVRT, isovolumic relaxation time; S’, systolic myocardial velocity; TDI, tissue Doppler imaging. *P < 0.05, third trimester vs. baseline.
