Background: Pre-eclampsia with severe features (PEC) is a pregnancy-related condition marked by severe hypertension and end-organ dysfunction, as well as short-term adverse cardiovascular events such as heart failure, pulmonary edema, and stroke.
The authors wanted to see how right ventricular (RV) systolic pressure (RVSP) and echocardiographic-derived diastolic, systolic, and speckle monitoring parameters changed over time in women with PEC.
The authors enrolled 63 women with PEC and 36 pregnant control patients in this prospective retrospective study.
The following are the outcomes:
As compared to the control cohort, the PEC cohort had a higher RVSP (31.0 7.9 mm Hg vs. 22.5 6.1 mm Hg; p 0.001) and a lower global RV longitudinal systolic strain (RVLSS) (19.6 3.2 percent vs. 23.8 2.9 percent [p 0.0001]). There were significant differences (p 0.001) in mitral septal e′ velocity (9.6 2.4 cm/s vs. 11.6 1.9 cm/s), septal E/e′ ratio (10.8 2.8 vs. 7.4 1.6), left atrial area size (20.1 3.8 cm2 vs. 17.3 2.9 cm2), and posterior and septal wall thickness for left-sided cardiac parameters (median [interquartile range]: 1.0 cm [0.9 to 1.1 cm] vs. 0.8 cm [0.7 to 0.9 cm], and 1.0 cm [0.8 to 1.2 cm] vs. 0.8 cm [0.7 to 0.9 cm]). PEC was seen in eight women (12.7%) with grade II diastolic dysfunction and six women (9.5%) with peripartum pulmonary edema.
When compared to healthy pregnant women, women with PEC have higher RVSP, higher rates of irregular diastolic activity, decreased global RVLSS, increased left-sided chamber remodeling, and higher rates of peripartum pulmonary edema.
