“…In pregnancy, a previous cross-sectional study suggested that longitudinal function (assessed by M-mode) might deteriorate prior to circumferential function [assessed by EF and FS (fractional shortening)] [32]. With normal aging, a deterioration in longitudinal function, with preservation of circumferential function, has also been reported [43].…”

The aim of the present study was to undertake a longitudinal study of systolic and diastolic cardiac function during normal pregnancy. At a median of 16 weeks of gestation, 100 primiparous women underwent echocardiography, including tissue Doppler imaging, determining left ventricular mass, cardiac output, systolic and diastolic velocities, and wall stress. A total of 32 were assessed again at a median of 37 weeks of gestation. Non-pregnant control estimates (n=9) were obtained by averaging four separate measures over two menstrual cycles. Initially, the pregnant women had significantly higher pulse rates than controls, associated with greater ventricular wall stress (two-tailed P value=0.015), and systolic (two-tailed P value=0.005) and diastolic (two-tailed P value=0.018) lateral wall myocardial velocities, but no differences in systolic blood pressure, left ventricular mass or cardiac output. By 37 weeks of gestation, increased blood pressure (two-tailed P value<0.001) and left ventricular mass (two-tailed P value=0.002) were associated with a significant increase in ventricular wall stress (two-tailed P value<0.001), and reductions in septal systolic (two-tailed P value=0.004) and septal and lateral early diastolic (two-tailed P value<0.001) myocardial velocities. The diastolic velocities at 37 weeks correlated inversely with maternal weight and age. In conclusion, by term pregnancy, an increase in ventricular wall stress is accompanied by a deterioration in cardiac function.

Objective To compare maternal cardiac function in women with intrauterine growth restriction (IUGR) to those with small-for-gestational age (SGA) pregnancies (non-IUGR). Methods This was a cross-sectional study involving maternal echocardiography and uterine, umbilical and fetal middle cerebral artery Doppler assessment in 52 normotensive women at 20-36 weeks' gestation with SGA fetuses (26 IUGR and 26 non-IUGR). Results In the IUGR (compared to the non-IUGR) group

Maternal left ventricular transverse and long‐axis systolic function during pregnancy

Abstract: Changes in left ventricular long-axis performance during pregnancy occur earlier than do measures of transverse function.
