Background: 2nd & 3rd trimester of pregnancy is associated with profound adaptive autonomic cardiovascular
changes. Anaemia in pregnancy, which is a common problem in India is known to put pregnant female at
higher cardiovascular risk.
Objective: The aim of this study is to measure & compare DBP response to CPT in both trimester in
both control group & pregnancy with moderate anaemia (Case) for screening & diagnosis of autonomic
imbalance.
Method: After measuring vitaldata, anthropometric data, DBP response to CPT were measured & compared
among control & case group (13-39 weeks of gestation) in sitting position.
Result: A highly significant difference in Wt, SBP, DBP were observed in control group of 2nd trimester
when compared with 3rd trimester. A highly significant difference was observed in Wt, DBP, DBP response
to CPT of case group of 2nd trimester when compared with 3rd trimester; A highly significant difference
was observed in Hb, SBP, DBP of case group of 3rd trimester when compared with control group during
3rd trimester of pregnancy;The chi-square test value shows that the observed DBP response to CPT in
moderately anaemic pregnancy during 2nd & 3rd trimester is not due to chance.
Conclusion: This study has found CPT as simple, safe, cost effective, reliable test aiding to understand
pathophysiology of anaemia during late gestation. It is also useful tool to predict & screen high risk pregnancy
among anaemic pregnancies for early intervention.
