Insights
Higher leukocyte and neutrophil counts, along with the neutrophil-lymphocyte ratio (NLR), are linked to severe coronary lesions in acute myocardial infarction (AMI) patients. Neutrophil count may predict high thrombus burden and total coronary occlusion.
Area of Science:
- Cardiology
- Hematology
- Biomedical Science
Background:
- Leukocytes are crucial in acute myocardial infarction (AMI) development and progression.
- Understanding the link between leukocyte counts and coronary lesion severity is vital for patient management.
Purpose of the Study:
- To investigate the association between leukocyte count and coronary lesion severity in patients with AMI.
- To determine if leukocyte count, neutrophil count, or neutrophil-lymphocyte ratio (NLR) predict adverse cardiovascular events during hospitalization.
Main Methods:
- A retrospective study of 815 AMI patients undergoing primary percutaneous coronary intervention (2005-2014).
- Analysis of risk factors, routine blood parameters, and in-hospital cardiovascular events.
- Comparison of leukocyte counts, neutrophil counts, and NLR between thrombus burden and total occlusion groups.
Main Results:
- Leukocyte count, neutrophil count, and NLR were significantly higher in patients with high thrombus burden and total coronary occlusion.
- A neutrophil count ≥8.355 × 10^9/L was independently associated with high thrombus burden and total coronary occlusion.
- No significant relationship was found between leukocyte count, neutrophil count, NLR, and in-hospital cardiovascular events.
Conclusions:
- Neutrophil count may serve as an independent predictor of high thrombus burden and total coronary occlusion in AMI patients.
- Leukocyte parameters are associated with coronary lesion severity but not necessarily with in-hospital cardiovascular events.
Abstract:
Leukocytes play a pivotal role in the onset and progression of acute myocardial infarction (AMI). We evaluated the relationship between leukocyte count and coronary lesion severity of AMI. We carried out a retrospective study involving 815 patients with AMI undergoing primary percutaneous coronary intervention from 2005 to 2014 at a cardiovascular center. We recorded their risk factors, routine blood parameters, and cardiovascular events during hospitalization. When thrombus and nonthrombus burden groups were compared, leukocyte count (9.55 [7.80, 12.29] vs 10.70 [8.67, 13.04]×109/L, P = .005), neutrophil count (7.48 [5.65, 10.18] vs 8.61 [6.61, 10.80]×109/L, P = .001), and neutrophil-lymphocyte ratio (NLR; 4.99 [2.97, 7.16] vs 10.70 [8.67, 13.04], P = .003) were significantly different. Patients in the total occlusion group showed higher leukocyte count, neutrophil count, and NLR compared to the nontotal occlusion group. After multivariate logistic analysis, a neutrophil count ≥8.355 × 109/L was independently associated with high thrombus burden and total coronary occlusion. Leukocyte count, neutrophil count, or NLR was not significantly related to cardiovascular events during hospitalization. In conclusion, the neutrophil count might be an independent predictor of high thrombus burden and total coronary occlusion.
