Cardiac output shifts days before symptoms do — but most monitoring systems miss this key windown

In conditions like heart failure, cardiac output begins to decline before a patient feels anything, and well before clinicians are able to observe changes. By the time intervention happens, it is often reactive, and often in the hospital. Measuring cardiac output continuously from inside the body closes that gap, turning a late crisis into an early signal.
