Insights
Hematological parameters like neutrophil-lymphocyte ratio and mean platelet volume-to-lymphocyte ratio can help predict the no-reflow phenomenon after primary percutaneous coronary intervention. However, no single parameter showed superior predictive capacity for identifying high-risk patients.
Area of Science:
- Cardiology
- Hematology
- Interventional Cardiology
Background:
- The no-reflow phenomenon complicates ST-segment elevation myocardial infarction (STEMI) treatment, leading to adverse outcomes.
- Early identification of patients at high risk for no-reflow is crucial for clinical management.
Purpose of the Study:
- To evaluate and compare the predictive utility of various hematological parameters for early identification of the no-reflow phenomenon.
- To assess hematological markers during primary percutaneous coronary intervention (PCI) in STEMI patients.
Main Methods:
- A cohort of 612 STEMI patients undergoing primary PCI was analyzed.
- Patients were categorized into no-reflow and normal reflow groups based on reflow status.
- Hematological parameters were measured on admission, and their predictive values were assessed using sensitivity, specificity, and ROC analysis.
Main Results:
- No-reflow patients exhibited significantly higher neutrophil count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume-to-lymphocyte ratio (MPVLR).
- MPVLR demonstrated moderate predictive value and high specificity (66.8%) for no-reflow.
- NLR yielded the largest area under the curve (AUC) for predicting no-reflow, though no significant difference in predictive utility was found among the evaluated parameters.
Conclusions:
- MPVLR shows moderate performance in predicting no-reflow.
- No single hematological parameter on admission demonstrated a definitively superior ability to predict no-reflow in STEMI patients undergoing primary PCI.
Objective:
Because the no-reflow phenomenon in patients with ST- segment elevation myocardial infarction can lead to poor outcomes and early identification of patients at high risk may alter the clinical outcome, we aimed to study possible differences in the predictive utility among hematological parameters for early identification of patients at high risk of the no-reflow phenomenon during the primary percutaneous coronary intervention.
Methods:
A total of 612 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were enrolled. The patients were divided into 2 groups: no-reflow and normal reflow. Hematological parameters were measured on admission. Sensitivity, specificity, positive and negative predictive values, and receiver-operating characteristic areas under the curve were determined to evaluate the predictive values of these parameters.
Results:
The patients in the no-reflow group had a significantly higher neutrophil count, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and mean platelet volume-to-lymphocyte ratio when compared to the normal reflow patients. We identified mean platelet volume-to-lymphocyte ratio to have a moderate predictive value and high specificity (66.8%) for the no-reflow phenomenon. Neutrophil-lymphocyte ratio provided the largest area under the curve for predicting no reflow. Regarding the predictive utility for no reflow, the comparison showed no statically significant differences among evaluated hematological parameters.
Conclusion:
For the prediction of no reflow, mean platelet volume-to-lymphocyte ratio yielded moderate performance. No hematological parameter on admission had persuasive superior capacities to predict no-reflow in patients receiving the primary percutaneous coronary intervention.

The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
