Insights
Mean platelet volume (MPV) can predict the location of myocardial infarction in the left anterior descending artery (LAD) and identify patients with non-ST-elevation myocardial infarction (NSTEMI) at higher risk for in-hospital events.
Area of Science:
- Cardiology
- Thrombosis Research
- Clinical Diagnostics
Background:
- Platelets are crucial in atherothrombosis, a leading cause of myocardial infarction.
- The left anterior descending artery (LAD) is a common site for plaque rupture, and LAD infarct location is linked to poorer prognosis.
- Predicting infarct location and patient outcomes in non-ST-elevation myocardial infarction (NSTEMI) is clinically significant.
Purpose of the Study:
- To investigate if mean platelet volume (MPV) can predict LAD infarct location in NSTEMI patients.
- To assess the association between MPV and short-term clinical outcomes in NSTEMI.
- To compare the predictive value of MPV against other clinical and laboratory markers for infarct localization.
Main Methods:
- A cohort of 190 consecutive NSTEMI patients was studied.
- Data collected included clinical characteristics, electrocardiography, laboratory tests, and coronary angiography.
- Multivariate analysis and receiver operating characteristic (ROC) curve analysis were employed to evaluate MPV's predictive capabilities.
Main Results:
- MPV was significantly lower in patients with LAD infarcts compared to those with left circumflex or right coronary artery infarcts (9.0 ± 1.5 vs. 9.8 ± 1.6, p<0.001).
- MPV emerged as the sole independent predictor of LAD infarct location (OR=0.65, p<0.0001).
- MPV also predicted major in-hospital events in NSTEMI patients (OR=1.46, p<0.01) and demonstrated reliable discrimination (AUC=0.65).
Conclusions:
- Mean platelet volume is the only independent factor associated with LAD infarct location in NSTEMI patients.
- MPV serves as a valuable biomarker for predicting infarct location and short-term adverse events in NSTEMI.
- Electrocardiography and B-type natriuretic peptide were found to be unreliable for culprit vessel localization.
Abstract:
Platelets play an important role in atherothrombosis. As the most common site plaque occurs, left anterior descending artery (LAD) infarct location always associate with poor prognosis. We sought to assess whether mean platelet volume (MPV) could predict LAD infarct location and short-term clinical outcome. In this study, 190 consecutive patients with non-ST-elevation myocardial infarction (NSTEMI) were enrolled. Clinical, electrocardiography and laboratory characteristics were measured. All patients underwent coronary angiography examination and had definite culprit vessel during hospitalization. The results showed that MPV was smaller in patients with a LAD infarct location than that of left circumflex artery or right coronary artery (9.0 ± 1.5 versus 9.8 ± 1.6, p<0.001). Multivariate analysis also showed that MPV was the only independent factor to predict LAD infarct location [Odds ratio (OR)=0.65, 95% confidence interval (CI) 0.53-0.80, p<0.0001] in patients with NSTEMI. B-type natriuretic peptide and electrocardiography were unreliable predictive factors to locate culprit vessel. Receiver operating characteristic curve analysis showed MPV (area under the curve: 0.65, 95% CI 0.56-0.74, p<0.01) could reliably discriminate those patients with NSTEMI who had a major in-hospital event. Multivariate regression analyses also showed that MPV (OR=1.46, 95% CI 1.15-1.86, p<0.01) were predictors of major in-hospital events. In conclusion, MPV was the only factor independently associated with LAD infarct location in patients with non-ST-elevation myocardial infarction.
