Study of Heart Rate Variability and Blood Flow Changes During Pregnancy and After Birth in Women

What this Trial Is About

Researchers are studying how heart rate variability HRV relates to changes in blood flow and heart function during pregnancy and after childbirth. This observational study aims to understand how the nervous system controls the heart throughout pregnancy, which undergoes significant cardiovascular changes. Understanding these changes is important for monitoring heart health and predicting possible complications during pregnancy and postpartum. Participants will be monitored at specific times during pregnancyweeks 13, 27, and 41and at 1, 3, 6, and 12 months after giving birth. The study involves measuring many different heart and blood pressure indicators, including RR intervals, heart rate turbulence, blood pressure, cardiac output, and vascular resistance. Researchers will also assess physical activity, anxiety, depression, and pregnancy-related health events during these periods. Participants will have regular assessments involving heart rate and blood pressure measurements, blood tests for pregnancy-related proteins, and questionnaires about physical activity and mental health. These evaluations will help researchers track cardiovascular adaptations and health outcomes over time. The study includes data collection on hospitalizations and pregnancy complications, extending up to one year postpartum, to provide a comprehensive view of cardiovascular health changes.
