Abstract
The present study is a systematic review of the literature that aimed to characterize
the profile in animal models used to study perinatal protein malnutrition correlating
with the cardiovascular system and the implications of malnutrition to the heart.
Therefore, an extensive search was conducted in the PubMed, BVS, and SciELO databases,
using combinations of the descriptors protein malnutrition, pregnancy, heart, lactation, and cardiovascular system. A total of 247 articles were found, but after excluding duplicities and applying
the inclusion/exclusion criteria, only 12 papers remained. The analysis of the results
shows that the diet used in the studies has a protein content of between 17 and 22%
for the control animals, and of between 0 and 9% for the animals submitted to perinatal
protein malnutrition. The main morphofunctional changes observed in the cardiovascular
system are related to high blood pressure, increased apoptosis of cardiomyocytes,
and reduction in the absolute size of the heart, among other ultrastructural and molecular
changes.
