What this trial studies

The Nanowear SimpleSense study is an observational trial designed to validate the SimpleSense wearable system for estimating cardiac output in patients undergoing right heart catheterization. It consists of two phases: the first phase will correlate data from the SimpleSense device with values obtained from right heart catheterization, while the second phase will evaluate algorithms developed to estimate cardiac output using data from a separate group of subjects. The study aims to enroll up to 100 participants at Westchester Medical Center over the course of one year.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are scheduled for right heart catheterization due to conditions like advanced heart failure or candidacy for heart transplant.

Not a fit: Patients who are pregnant or have severe aortic stenosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive method for monitoring cardiac output, improving patient management in heart-related conditions.

How similar studies have performed: Other studies have explored wearable technology for cardiac monitoring, but this specific approach using the SimpleSense system is novel.
