Q: One of the deceiving forms of acute congestive heart failure is "occult shock", where it may be difficult to distinguish end-stage CHF patients from mildly decompensated CHF patients. Which one lab test may be vital and ideally should be obtained in all patients with acute decompensated CHF?
Answer: Lactic acid
One of the deceiving forms of acute congestive heart failure is "occult shock", where it may be difficult to distinguish end-stage CHF patients from mildly decompensated CHF patients. High lactate level indicates acute emergency in such patients and may require relatively early initiation of inotrope, floatation of pulmonary artery catheter (PAC) to guide the volume management and managing perfusion to other vital organs.
