Interestingly, CHF patients did not have worse outcomes in admission vital signs (oxygen saturation, temperature, and mean arterial pressure), inflammatory indicators at admission [ferritin, C-reactive protein, and procalcitonin, but not WBC, lymphocytes, or IL-6], or in-hospital mortality compared with non-CHF patients (all p > 0.05). Here, IL6 is linked to congestive heart failure.
