Insights
The lactate dehydrogenase (LDH)/lymphocyte ratio (L-LWR) effectively predicts in-hospital mortality in infective endocarditis (IE) patients. This easily applicable marker demonstrates good performance and reliability for assessing prognosis in IE.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Diagnostics
Background:
- Infective endocarditis (IE) is associated with high mortality and poor prognosis.
- Predictive markers for in-hospital mortality in IE patients are crucial for clinical management.
Purpose of the Study:
- To evaluate the predictive value of the lactate dehydrogenase (LDH)/lymphocyte ratio (L-LWR) for in-hospital mortality in IE patients.
- To compare the efficacy of L-LWR with the LDH/lymphocyte percentage (L-LWR) in predicting outcomes.
Main Methods:
- Retrospective analysis of medical records from 147 IE patients (January 2017 - December 2019).
- Selection of admission indexes for statistical analysis.
- Comparison of L-LWR and LDH/lymphocyte levels between patients with and without adverse events.
Main Results:
- IE patients without adverse events showed significantly higher LDH/lymphocyte levels and lower L-LWR.
- L-LWR remained an independent predictor of mortality after adjustments (OR: 4.558, P=0.014).
- L-LWR demonstrated high predictive accuracy (AUC: 0.780) with good sensitivity (81.89%) and specificity (65.00%) at a cutoff of 34.
Conclusions:
- L-LWR is a reliable, cost-effective, and easily applicable prognostic marker for in-hospital mortality in IE.
- The L-LWR shows good performance and independence in predicting outcomes for patients with infective endocarditis.
Background:
Infective endocarditis (IE) has a high rate of mortality and the prognosis of IE was poor. The purpose of this investigation was to explore the value of lactate dehydrogenase (LDH)/lymphocyte and compare it with LDH/lymphocyte percentage (L-LWR) in predicting the in-hospital mortality in IE patients.
Methods:
The investigation cohort contained 147 IE patients between January 2017 and December 2019. We retrospectively went over the medical records and selected admission indexes.
Results:
Compared with IE patients with adverse events, significantly higher levels of LDH/lymphocyte and significantly lower levels of L-LWR were discovered in IE patients without adverse events. After adjustments, L-LWR (odds ratio (OR): 4.558, 95% confidence interval (CI) 1.362-15.256, P = 0.014) still maintained its significant independence. In addition, L-LWR had the highest area under curve (AUC) (0.780, 0.704-0.844, P < 0.001) with good sensitivity (81.89%) and specificity (65.00%) when 34 was selected as the best cutoff value.
Conclusions:
L-LWR is a reliable, low-priced, easily applicable, and independent prognostic parameter for in-hospital death with good performance in patients with IE.
