Insights
The neutrophil-to-lymphocyte ratio (NLR) may help identify left ventricular diastolic dysfunction (LVDD) in type 2 diabetes patients. Higher NLR levels correlate with increased LVDD prevalence, suggesting it as a potential diagnostic indicator.
Area of Science:
- Cardiology
- Endocrinology
- Inflammation Biomarkers
Background:
- Diabetes mellitus is a global pandemic linked to severe health complications.
- Left ventricular diastolic dysfunction (LVDD) is a common, often asymptomatic, cardiac complication in diabetic patients.
- The neutrophil-to-lymphocyte ratio (NLR) is an inflammation biomarker with potential links to cardiac conditions, but its association with LVDD in type 2 diabetes mellitus (T2DM) remains unexplored.
Purpose of the Study:
- To investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR) and left ventricular diastolic dysfunction (LVDD) in patients with type 2 diabetes mellitus (T2DM).
Main Methods:
- A cross-sectional study analyzed medical records of 855 T2DM patients.
- Patients were classified into LVDD and non-LVDD groups based on echocardiographic criteria.
- The correlation between NLR levels and LVDD prevalence was statistically evaluated.
Main Results:
- The prevalence of LVDD was 47.8% among the studied T2DM patients.
- Patients with LVDD exhibited significantly higher mean NLR values compared to those without LVDD (P<0.001).
- Logistic analysis revealed a positive association between NLR levels and LVDD prevalence, with elevated NLR correlating to increased odds of LVDD (P<0.001).
Conclusions:
- The neutrophil-to-lymphocyte ratio (NLR) shows potential as an indicator for identifying LVDD in T2DM patients.
- Elevated NLR levels may signify a higher risk of LVDD, warranting clinical attention and intervention to prevent progression to heart failure.
Background:
Diabetes has become a global pandemic, posing a sustained threat to human health, primarily due to its associated complications. Left ventricular diastolic dysfunction (LVDD) is a prevalent cardiac complication among patients with diabetes. Since most patients are asymptomatic and lack relevant biomarkers, LVDD has not attracted significant attention from clinicians. The neutrophil-to-lymphocyte ratio (NLR) is a widely studied inflammation biomarker that has been suggested to be linked to various medical conditions, including cardiac diseases. However, its association with LVDD among patients with type 2 diabetes mellitus (T2DM) has not been explored.
Aim:
To clarify the relationship between NLR and LVDD among patients with type 2 diabetes.
Methods:
We conducted a cross-sectional study using medical records from 855 patients diagnosed with T2DM who were admitted to the Endocrinology department at Wuhan Union Hospital. According to the ASE/EACVI 2016 recommendations, these patients were categorized into two groups based on sonographic parameters: patients with normal left ventricular diastolic function (the non-LVDD group) and patients with LVDD (the LVDD group). NLR values were calculated and divided into three different levels. Statistical analysis was conducted to evaluate the correlation between NLR levels and the prevalence of LVDD.
Results:
The prevalence of LVDD among hospitalized patients with T2DM in our study was 47.8% (409/855). The mean NLR value of the LVDD group was significantly higher compared with the non-LVDD group [1.60 (1.24-2.05) vs 1.85 (1.44-2.31), P<0.001]. The prevalence of LVDD in the three different NLR levels was 35.51% (76/214), 49.27% (203/412), and 56.77% (130/229), respectively. Unjustified logistic analysis showed that NLR levels were positively associated with the prevalence of LVDD (P <0.001). Compared to the low level of NLR, the unadjusted odds ratios (OR) of LVDD at the medium and high levels were 1.764 (1.255-2.478, P=0.001) and 2.384 (1.626-3.497, P<0.001), respectively (P for trend <0.001).
Conclusion:
Our findings suggest that the NLR is a potential indicator for assisting clinicians in identifying LVDD in patients with T2DM. Patients with elevated NLR levels may be at a greater risk of developing LVDD than those with lower NLR levels, which may require attention and interventions to prevent patients from progressing into heart failure.
