Isolated right atrial tissue from cardiac-surgery patients
How the study was set up
Right-atrial tissue obtained during surgery from adults with severe coronary disease was studied outside the body.
What the researchers measured
Contraction force and relaxation time were measured alongside receptor-blocking and cell-signaling experiments.
How to read this evidence
This paper examines laboratory measurements or analytical methods. It is not a study of treatment outcomes in people.
Results in context
The tissue showed contraction responses under laboratory conditions. Human-derived tissue does not make this a trial of heart function, cardiovascular benefit, or safety in patients.
What this does not establish
Patient-derived tissue outside the body remains laboratory evidence. This does not establish cardiac benefit, arrhythmia risk, or clinical safety in people.
