Cardiovascular changes during Pregnancy, Labour and Puerperium

Dr. C. Indira Devi, Dr. S. Srikanth

Abstract :

 Background & Objectives: Maternal physiology undergoes many changes during pregnancy which are largely secondary to the effects of progesterone and estrogen which are produced predominantly by the ovary in the first 12 weeks of pregnancy and thereafter, produced by the placenta. These changes enable the fetus and placenta to grow and prepare the mother and baby for childbirth. Materials & Methods: This is a longitudinal study conducted among 30 female subjects in age group 18 to 30 years. Heart rate, Blood pressure (SBP, DBP, and MABP) was measured. SV and CO were calculated using Echocardiography. Results: In our study, we observed an increase in heart rate, SBP, SV and CO with a decrease in hematocrit during the three trimesters of pregnancy. Conclusion: We observed a gradual increase in SBP with a peak value during labour and also found an increase in SBP in puerperium. The DBP and mean arterial BP decreased to maximum during second trimester and an increase in DBP and mean arterial BP was observed from labour till day 1 of puerperium.DBP decreased during first and second week of puerperium with a slight increase in mean arterial BP. SV and CO gradually increased and reached a maximum during labour and continued to increase during puerperium. Summary: The cardiovascular physiological adaptations of pregnancy represent an efficient oxygen carrying capacity state which delivers adequate oxygen and nutrients for both the mother and fetus. Cardiovascular disorders remain an important cause of maternal morbidity and mortality and of adverse fetal outcomes. Hypertensive disorders account for a significant proportion of this group of pregnancy–associated complications. Understanding the normal cardiovascular changes in pregnancy is essential to cå for patients with cardiovascular disease
