Insights
The platelet-to-lymphocyte ratio (PLR) is elevated in patients with mitral annular calcification (MAC). Higher PLR levels are independently associated with the presence of MAC, suggesting its potential as a biomarker.
Area of Science:
- Cardiology
- Hematology
- Biomarkers
Background:
- Mitral annular calcification (MAC) shares risk factors and pathogenesis with atherosclerosis.
- Increased platelet-to-lymphocyte ratio (PLR) is linked to atherosclerotic diseases.
Purpose of the Study:
- To investigate the association between PLR levels and the presence of MAC.
- To determine if PLR can serve as a biomarker for MAC.
Main Methods:
- A cohort of 1060 patients (704 with MAC, 356 without) was analyzed.
- Demographic, clinical, and laboratory data, including complete blood count for PLR calculation, were collected.
- Statistical analysis identified independent predictors of MAC.
Main Results:
- Patients with MAC were older and had higher rates of hypertension.
- Mean PLR was significantly higher in the MAC-positive group (129.1 vs 103.5, p < 0.001).
- PLR, along with age, hypertension, and NLR, was independently associated with MAC presence (OR: 1.109).
Conclusions:
- PLR is significantly increased in patients with MAC.
- PLR is an independent predictor of MAC presence.
- Elevated PLR may indicate an increased risk or presence of MAC.
Objectives:
Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased platelet-to-lymphocyte ratio (PLR) has been shown to be associated with atherosclerotic diseases in previous studies. In this study, we aimed to show the association of PLR levels with the presence of MAC.
Design:
A total of 1060 patients [n = 704 MAC (+), and n = 356 MAC (-)] who were admitted to our cardiology department were enrolled between January 2014 and December 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. PLR was calculated from the complete blood count.
Results:
The MAC (+) group comprised of those older in age and having a higher rate of hypertension. The mean PLR value was also significantly higher in the MAC (+) group, as compared to that in the MAC (-) group (129.1 ± 32.2 vs 103.5 ± 23.8, p < 0.001). There was a statistically significant and positive correlation between the neutrophil-to-lymphocyte ratio (NLR) and PLR (r = 0.644, p < 0.001). Age, hypertension, mean platelet volume, NLR, and PLR (OR: 1.109, 95% CI: 1.101-1.123, p < 0.001) were independently associated with the presence of MAC.
Conclusions:
Our results demonstrated that the PLR was significantly increased in patients with MAC, and that the PLR was independently associated with the presence of MAC.
