The pan-immune-inflammation value (PIV) integrates neutrophil, platelet, monocyte, and lymphocyte counts as a prognostic biomarker in acute coronary syndrome (ACS) patients.
-
2
Nineteen cohort studies involving 18,715 patients were included, showing higher PIV associated with major adverse cardiovascular events (MACE) and all-cause mortality.
-
3
Elevated PIV demonstrated consistent discrimination for angiographic no-reflow or slow-flow, with an AUC of 0.828, indicating moderate certainty.
-
4
The evidence for PIV's association with cardiac mortality was limited, with only one study reporting an HR of 3.24 and low certainty.

The review highlights the need for prospective validation of PIV and comparison with established inflammatory indices before clinical implementation.
