Why the study?

How does normal pregnancy affect maternal left ventricular performance as measured by 3D speckle-tracking echocardiography compared to nonpregnant controls?

Population

68 pregnant women and 30 age-matched, healthy, nonpregnant women serving as controls (total n=98).

Comparison

Observation during each pregnancy trimester and… vs Age-matched, healthy, nonpregnant women.

Design

Cohort

Follow-up

6 to 9 weeks after delivery

Overview

Transient LV strain/EF reductions in late pregnancy recover postpartum; leaves open 3D STE thresholds for peripartum cardiomyopathy detection.

Structured PICO

How does normal pregnancy affect maternal left ventricular performance as measured by 3D speckle-tracking echocardiography compared to nonpregnant controls?

P
Population
68 pregnant women and 30 age-matched, healthy, nonpregnant women serving as controls (total n=98).
I
Intervention
Observation during each pregnancy trimester and 6 to 9 weeks postpartum using two-dimensional echocardiography (2DE) and three-dimensional speckle-tracking echocardiography (3D STE).
C
Comparator
Age-matched, healthy, nonpregnant women.
O
Outcome
Maternal left ventricle performance measured by 3D speckle-tracking echocardiography parameters (Global longitudinal strain [GLS], global circumferential strain [GCS], global area strain [GAS], and global radial strain [GRS]).surrogate

3D speckle-tracking echocardiography reveals transient, physiological reductions in myocardial strain and ejection fraction during late pregnancy that recover postpartum.
