Key result
Lower admission sGP-VI levels (≤ 25 ng/mL) were independent predictors of angiographic no-reflow phenomenon in patients with STEMI undergoing primary PCI (P<0.001).
Why the study?

Is admission soluble glycoprotein VI (sGP-VI) level associated with the no-reflow phenomenon after primary percutaneous coronary intervention in patients with acute STEMI?
Lower admission sGP-VI levels (≤ 25 ng/mL) are independently associated with the development of angiographic no-reflow phenomenon in STEMI patients undergoing primary PCI.

OBJECTIVES: The purpose of this study was to determine whether admission soluble glycoprotein VI (sGP-VI) level is associated with no-reflow phenomenon (NRP) after primary percutaneous coronary intervention (P-PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 178 consecutive patients admitted to our hospital for a first STEMI and undergoing P-PCI within 12 hours of onset of symptoms were enrolled. The patients were divided into 2 groups (NRP group and reflow group). Admission sGP-VI plasma levels were measured by enzyme-linked immunosorbent assay. RESULTS: Of the 178 patients who underwent P-PCI, 41 patients (23%) developed NRP. The patients in the reflow group had higher levels of sGP-VI compared with the patients in the NRP group (38.5 ± 21.0 vs 21.9 ± 11.9 ng/mL, P < 0.001). The sensitivity and specificity values of the sGP-VI levels were 90% and 49%, respectively (cutoff value was ≤ 25). In the multivariate logistic regression analyses, sGP-VI levels of 25 ng/mL or lower, higher peak troponin T levels and body mass index value, amount of opaque of greater than 250 mL, and lesion length of greater than 13.5 mm were independent predictors of angiographic NRP. CONCLUSIONS: Lower admission sGP-VI levels are associated with NRP in patients with STEMI undergoing P-PCI. This outcome may open new therapeutic facility in the setting of P-PCI.

Kobat et al. (2014) conducted an observational in Acute ST-segment elevation myocardial infarction (STEMI) (n=178). Admission soluble glycoprotein VI (sGP-VI) level ≤ 25 ng/mL vs. sGP-VI level > 25 ng/mL was evaluated on No-reflow phenomenon (NRP) after primary percutaneous coronary intervention (p=<0.001). Lower admission sGP-VI levels (≤ 25 ng/mL) were independent predictors of angiographic no-reflow phenomenon in patients with STEMI undergoing primary PCI (P<0.001).
