To the Editor: Dr Polanczyk and colleagues1 concluded that, after controlling for disease severity,
postoperative cardiac events and outcomes were no different in patients who
received RHC vs those who did not. It is debatable, however, whether these
are suitable end points for studying an intervention such as RHC, which has
2 functions. First, it can be used as a diagnostic tool, such as in differentiating
the etiology of shock. Second, it can be used to guide therapy with fluids
or vasoactive drugs. However, RHC itself is not therapeutic.
