Characterization Of Pregnancy Induced Cardiac Hypertrophy In Rats, Patricia Holden

Online Theses and Dissertations

During pregnancy, an increase in blood volume occurs to compensate for fetal development, resulting in cardiac hypertrophy. For the majority of women, this physiological cardiac hypertrophy resolves following pregnancy. Prolonged cardiac hypertrophy can lead to heart failure. We propose that by studying the biochemical mechanisms that mediate healthy cardiac remodeling associated with pregnancy, we will gain a better understanding of mechanisms involved in pathological cardiac hypertrophy. To determine the biochemical changes that occur during pregnancy induced cardiac remodeling, we subjected rats to timed matings and collected morphological and biochemical data from not pregnant, 19 days pregnant, and 24 hours postpartum. …
