Abstract
INIGO-RIESGO, Carmen Armida; GOMEZ-VARGAS, Juan Rafael; GUTIERREZ-FAJARDO, Pedro and TORRES-GOMEZ, Luis Guillermo. Echocardiographical findings in pregnancy and late postpartum of healthy mexicans women´s. Ginecol. obstet. Méx. [online]. 2020, vol.88, n.5, pp.296-305. Epub Sep 20, 2021.

OBJECTIVE:
The aim of this prospective, observational and longitudinal study, was to evaluate and to compare the maternal adaptation through changes on anthropometric and Doppler echocardiographic parameters in Mexican normal pregnancy with single product.
MATERIALS AND METHODS:
Prospective, observational, longitudinal study, from January 2014 to January 2017. Obstetric ecosonograms and echocardiographic Doppler studies were performed on 2nd and 3rd trimester and six months postpartum. Each patient was her own control. The data were analyzed using SPSS Windows 17, ANOVA for compared the 3 groups with P value < 0.05 was considered significant, as well as a non-parametric correlation of Pearson.
RESULTS:
There were thirty pregnant with a mean age 22.5 ± 3.1 years-old, between 2nd and 3rd trimester, with obstetrics ultrasound were corroborated gestational age. With transthoracic echocardiography, we found significant changes between 2nd trimester and 6 month post-partum, among the main, the left ventricle (LV) in diastole (cm), 4.5 ± 2.5 versus 4.2 ± 2.3 (p < 0.01), end diastolic left ventricle volume (mL) 93 ± 14.8, vs 78 ± 17.8 (p < 0.05). Stroke volume (mL) 99.5 ± 15.7 vs 86 ± 11.8 (p < 0.01). Systemic vascular resistance (dyne/sec/cm5 ) 870 ± 108 vs 1,262 ± 176 (p < 0.001). From, 2nd and 3rd trimester and postpartum, left atrial diameter (cm), 3.1 ± 4.4, 3.3 ± 4.4, 2.9 ± 4.3 (p < 0.001). Cardiac output (L/m), 6.8 ± 0.4, 7.0 ± 0.4, 4.7 ± 0.4 (p < 0.001).
CONCLUSION:
Pregnancy is a transitory overload condition with important organic and functional effects mainly in the second trimester.
