Abstract/OtherAbstract:
BACKGROUND: Gestational hypertension (GH) is associated with hemodynamic changes, and alterations of systolic and diastolic left ventricular (LV) function. However, the magnitude and pattern of changes of different parameters of LV function and contractility in this patient population have not been fully clarified.
METHODS: Thirty-five pregnant women with GH underwent three echocardiographic examinations, in second and third trimester of pregnancy, and 1 month after delivery. Twelve normotensive pregnant women served as gestational age-matched controls. Hemodynamic parameters and standard indexes of LV systolic and diastolic function were analyzed. Additionally, we have measured peak systolic velocity of mitral annulus (S'), end-systolic elastance (Ees), and early transmitral to early lengthening velocity of mitral annulus ratio (E/E') as parameters of longitudinal function, contractility, and filling, respectively.
RESULTS: Women with GH had initially higher body weight, blood pressure, and heart rate (P < 0.005, P < 0.0001, and P = 0.011, respectively). Temporal analysis of different echocardiographic parameters revealed increase in wall thickness from baseline to second measurement, with consequential increase in LV mass in women with GH (P = 0.014 for septum, P = 0.010 for posterior wall, and P = 0.09 for LV mass). No significant changes of LV volumes, ejection fraction (EF), transmitral flow parameters, S', Ees, and E/E' were observed throughout the follow-up in both groups (P = nonsignificant for all). Importantly, pattern of changes was similar in both groups for all examined parameters (P = nonsignificant between groups, for all).
CONCLUSIONS: It appears that changes of LV longitudinal function, filling, and contractility during pregnancy are not significant and not influenced by GH.
