Assessing Left Ventricular Systolic Function in Patients with Pregnancy-Induced Hypertension Using Three-Dimensional Speckle Tracking Technology.

ABSTRACT

Objective: This study investigates the clinical utility of three-dimensional speckle tracking technology in assessing left ventricular systolic function in pregnancy-induced hypertension syndrome (PIH). Methods: We retrospectively enrolled 70 patients with diagnosed PIH treated at our institution between July 2019 and August 2021 as the study group. A total of 70 healthy pregnant women undergoing routine antenatal examinations at the same institution during the same period were included in the control group. Two-dimensional conventional echocardiography measured left ventricular parameters in both groups. Three-dimensional speckle tracking technology analyzed Left Ventricular Global Longitudinal Peak Strain (LVGLS), Left Ventricular Global Radial Peak Strain (LVGRS), and Left Ventricular Global Circumferential Peak Strain (LVGCS). Differences in left ventricular systolic function and pregnancy outcomes were compared. Results: In the study group, LVEDD, LVPWTd, and IVSTd (47.67±4.88, 10.68±1.21, 11.24±1.03) exceeded those in the control group (45.21±5.65, 8.17±0.98, 8.91±0.37). LVEF (62.12±5.63) was lower than the control group (65.25±5.17) (all P < .05). LVGLS, LVGCS, and LVGAS in the study group (-15.66±1.07, -20.17±2.89, -23.17±3.43) were higher than the control group (-20.14±1.27, -25.17±1.36, -37.68±3.29), while LVGRS (30.29±3.61) was lower than the control group (34.18±4.08) (all P < .05). The study group had 72.86% natural deliveries and 27.14% cesarean sections; the control group had 31.43% natural deliveries and 68.57% cesarean sections (all P < .05). Weeks of delivery and birth weight in the study group (36.87±1.23, 2.71±0.41) were lower than the control group (38.96±1.54, 3.41±0.78) (both P < .05). Conclusions: Compared to traditional methods, three-dimensional speckle tracking technology more sensitively detects left ventricular strain and rotation in PIH patients. It holds clinical relevance in early left ventricular dysfunction detection, effectively mitigating adverse pregnancy outcomes and warranting clinical adoption and application.
