Key result
Pre-intervention platelet to lymphocyte ratio was significantly higher in STEMI patients who developed coronary no-reflow after primary PCI compared to those with normal reflow (139.65 vs 85.5, p<0.001).
Why the study?
No reflow after primary PCI increases morbidity and mortality, and the relation between admission platelet to lymphocyte ratio and angiographic reflow in STEMI needed assessment.
Does admission platelet to lymphocyte ratio predict angiographic no-reflow in STEMI patients undergoing primary PCI?
Population

Absolute Event Rate: 139.65% vs 85.5%
p-value: p=<0.001
Pre-intervention platelet to lymphocyte ratio is an independent predictor of angiographic slow flow or no-reflow in patients with STEMI undergoing primary PCI.
Emara et al. (2019) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=60). Platelet to lymphocyte ratio (PLR) vs. Normal reflow (TIMI III) was evaluated on Admission platelet to lymphocyte ratio (PLR) (p=<0.001). Pre-intervention platelet to lymphocyte ratio was significantly higher in STEMI patients who developed coronary no-reflow after primary PCI compared to those with normal reflow (139.65 vs 85.5, p<0.001).
