Insights
Elevated endocan levels predict the no-reflow phenomenon (NRP) in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Higher endocan indicates a greater risk of poor myocardial perfusion.
Area of Science:
- Cardiology
- Biomarkers
- Vascular Biology
Background:
- The no-reflow phenomenon (NRP) complicates primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI).
- Endocan, a marker of endothelial dysfunction and inflammation, is secreted by activated vascular endothelium.
- The association between endocan levels and NRP in STEMI patients remains to be fully elucidated.
Purpose of the Study:
- To investigate the relationship between serum endocan levels and the occurrence of NRP in STEMI patients undergoing pPCI.
- To determine if endocan can serve as an independent predictor of NRP.
Main Methods:
- A cohort of 137 consecutive STEMI patients undergoing coronary angiography and pPCI were enrolled.
- Clinical characteristics and serum endocan levels were measured for all participants.
- Statistical analyses, including multivariate analysis, were performed to assess the association between endocan and NRP.
Main Results:
- Endocan levels were significantly higher in patients with NRP compared to those without NRP (P < .001).
- Multivariate analysis identified endocan as an independent predictor of NRP (P < .001, OR = 2.39, 95% CI = 1.37-4.15).
- An endocan level >2.7 ng/mL demonstrated high sensitivity (89.6%) and specificity (74.2%) for predicting NRP (AUC: 0.832, P < .001).
Conclusions:
- Serum endocan level is an independent predictor of NRP in STEMI patients treated with pPCI.
- Measuring endocan levels may help identify patients at higher risk for insufficient myocardial perfusion and adverse clinical outcomes.
Abstract:
No-reflow phenomenon (NRP) is an important problem in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). Endocan is synthesized and secreted by activated vascular endothelium, and it has been shown to be related to endothelial dysfunction and inflammation. We aimed to evaluate the relationship between endocan levels and NRP. Consecutive patients (n = 137) with STEMI who had undergone coronary angiography and pPCI were enrolled into the study. The clinical characteristics of the patients were obtained and endocan levels were measured. Endocan levels were significantly higher in the NRP (+) group compared with the NRP (-) group (P < .001). In multivariate analysis, endocan (P < .001, OR = 2.39, 95% CI = 1.37-4.15) was found to be an independent predictor of NRP. An endocan value of >2.7 ng/mL has 89.6% sensitivity and 74.2% specificity for the prediction of the NRP (area under the curve: 0.832, P < .001). The present study demonstrated that the endocan level is an independent predictor of the NRP in patients with STEMI who underwent pPCI. Endocan levels may be helpful in detecting patients with a higher risk of insufficient myocardial perfusion and worse clinical outcome.
