Description
Steven Garcia and three colleagues test whether a wrist artery reading can stand in for a direct heart measure of squeezing strength, in a 2026 study of valve replacement patients. The direct measure, the rate of pressure rise in the left ventricle, is a standard gauge of heart muscle strength, yet it needs a catheter inside the heart.
Patients having a new aortic valve fitted by catheter had both measures recorded before and after the procedure. Before surgery the wrist reading sat far above the heart reading and tracked it weakly. After surgery the average gap shrank, yet agreement stayed poor. In 73 percent of patients the two measures moved in opposite directions across the procedure. The authors see the wrist signal as, at best, a rough guide to direction of change.
