INTRODUCTION
Physiological changes occur in all systems of the body
during pregnancy. The changes in the cardiovascular
system include an increase in the cardiac output, heart
rate and stroke volume throughout pregnancy, but the
systolic and diastolic blood pressures are found to
decrease during the second trimester.
1,2
These changes
are essential to meet the metabolic demands of the
mother as well as the fetus. Anemia is a major public
health problem that needs total elimination and is one of
the most commonly encountered medical disorders
during pregnancy. In developing country like India,
anaemia is a cause of serious concern and contributes to a
significantly higher maternal mortality. It accounts for
nearly 20-40% of maternal deaths and affects both
mother and fetus.

According to WHO, haemoglobin
level less than 11gm/dl in pregnant women constitutes
anaemia and haemoglobin level below 7 gm/dl is severe
anaemia. Severe anaemia during pregnancy is associated
with poor fetal outcomes.

term labour, pre-eclampsia, and sepsis have been
ABSTRACT
Background: Anaemia is a cause of serious concern and contributes to a significantly higher maternal mortality. Rate
Pressure Product (RPP) is a major determinant of myocardial oxygen consumption and blood flow. There is an
increase in oxygen demand in anemia. Thus, in the present study, we have compared the difference in RPP between a
normal pregnant women and pregnant women with anemia.
Methods: A total of 180 pregnant women (normal pregnant woman - 90 and pregnant woman with anaemia - 90)
belonging to different trimesters of pregnancy were included in the study. Age, height, and weight were recorded, and
their body mass index was calculated. The systolic blood pressure, diastolic blood pressure, heart rate was recorded
and RPP was calculated.
Results: There was a significant increase in RPP in pregnant woman with anaemia in all three trimesters of
pregnancy, but the significant increase was more in the third trimester.
Conclusions: The present study shows that there is an increase in RPP in pregnant woman with anaemia and they are
more prone to hemodynamic stress and cardiovascular risks, especially in their third trimester of pregnancy. This
hemodynamic change may be taken into account to prevent the cardiovascular complications associated with anemia
in pregnancy. Thus, RPP can be used as a sensitive non-invasive simple marker for early diagnosis of cardiovascular
disease in pregnant woman.
