A COMPARATIVE STUDY OF ECHOCARDIOGRAPHIC PARAMETERS IN INDIAN PREGNANT AND NONPREGNANT WOMEN
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 62
Abstract
BACKGROUND Pregnancy is a physiological stressful condition, which is accompanied by changes in cardiovascular parameters to fulfil the requirement of rapidly developing embryo and subsequent foetal growth. Serial evaluation has demonstrated noticeable changes in echocardiographic variables due to haemodynamic overload. Hence, it was proposed to estimate the degree of cardiovascular alteration during pregnancy in South Indian women. MATERIALS AND METHODS Uncomplicated singleton pregnancies in 1st, 2nd and 3rd trimesters (n= 10 in each group) along with healthy parous non-pregnant age matched women were used as control (n= 10) for this study. After recording baseline ECG and blood pressure, cardiovascular parameters were monitored using M-mode echocardiography and finally data were collected. RESULTS Results were analysed by ANOVA taking p < 0.05 as statistically significant. Among cardiac parameters, heart rate showed significantly higher values during pregnancy as gestation advanced (P= 0.003). But ECG could not demonstrate any significant difference throughout pregnancy. All of the echocardiographic parameters definitely showed alteration during various trimesters of pregnancy, but could not reach statistical significance which could be due to small sample size. CONCLUSION In view of these observations, it can be concluded that pregnancy leads to reversible left ventricular hypertrophy as a consequence of augmented venous return, which directly affects stroke volume resulting in physiological alteration in cardiopulmonary status of women. Understanding these alterations will help to extend proper antenatal care for safe motherhood and perinatal outcome.
