Detecting Pulse Waves in Pregnant Women

Prediction of Pregnancy Constitutions and Pregnancy Slippery Pulse Using ANSWatch

Observational China Medical University Hospital · NCT05428878

This study is testing a special watch to see how pulse waves in pregnant women compare to those in non-pregnant women to better understand heart health during pregnancy.

What this trial studies

This project aims to utilize a portable ANS Watch to measure pulse waves in pregnant women and compare them with non-pregnant women. The study will recruit 100 pregnant and 100 non-pregnant women to assess cardiovascular indices such as cardiac output and vessel stiffness. The ANS Watch is designed to predict traditional Chinese medicine pulses, particularly focusing on the slippery pulse, which is commonly observed in pregnant women. A neural network will be employed to analyze the data and provide predictions regarding pregnancy constitution and pulse characteristics.

Who should consider this trial

Good fit: Ideal candidates include non-pregnant females and singleton pregnant females aged 20 to 45 years without chronic diseases or recent medication use.

Not a fit: Patients with active heart disease, chronic illnesses requiring medication, or those currently experiencing acute conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of cardiovascular changes during pregnancy and improve prenatal care.

How similar studies have performed: While the use of pulse wave detection in pregnancy is a novel approach, similar studies in traditional Chinese medicine have shown promise in understanding pulse characteristics.
