Intermediate-Risk Chronic Stable Angina: Neutrophil-Lymphocyte Ratio and Fibrinogen Levels Improved Predicting Angiographically-Detected Coronary Artery Disease

Diagnostic value of fibrinogen in lower extremity deep vein thrombosis caused by rib fracture: A retrospective study

Objectives: To investigate the diagnostic value of fibrinogen (FIB) in patients with rib fractures complicated by lower extremity deep venous thrombosis (DVT).Methods: Analyzing data from 493 patients at Shijiazhuang Third Hospital, FIB levels at 24, 48, and 72 h post-injury were compared between DVT and non-DVT groups.Results: DVT group had elevated FIB levels at all times (p < .001). FIB at 24 h showed highest AUC, particularly in patients with BMI <28.Conclusion: In conclusion, measuring FIB at 24 h post-injury enhances DVT detection in rib fracture patients, with potential BMI-related variations.

Comparison of the Relationship Between Inflammatory Markers and Contrast-Induced Nephropathy in Patients With Acute Coronary Syndrome After Coronary Angiography

Contrast-induced nephropathy (CIN) is one of the most important complications after invasive cardiovascular procedures. The neutrophil-to-lymphocyte ratio (NLR), mean platelet volume-to-lymphocyte ratio (MPVLR), and platelet-to-lymphocyte ratio (PLR) may be markers of the risk of CIN. We aimed to investigate the association of these indices with the development of CIN in patients with ST-elevation myocardial infarction and non-ST-elevation-acute coronary syndrome who underwent percutaneous coronary intervention. We retrospectively collected the data of patients with ACS after coronary angiography (CA); 564 patients were included (mean age, 62.3 ± 13.0 years; 41.1% female). We compared 62 (10.9%) patients who developed CIN and 502 patients who did not, after CA in terms of NLR, PLR, and MPVLR. Patients who developed CIN had significantly higher MPVLR, NLR, and PLR; the MPVLR (P ≤ .001) was an independent predictor of CIN. NLR, MPVLR, and PLR are simple, cheap, and easily accessible tests that can predict CIN; the MPVLR was the strongest of these predictors.

Association between neutrophil-lymphocyte ratio and arterial stiffness in patients with acute coronary syndrome

The aim of the present study was to assess the association between neutrophil–lymphocyte ratio (NLR) and arterial stiffness and provide a predictive index for diagnosing atherosclerosis in patients with acute coronary syndrome (ACS). We enrolled patients with ACST who were confirmed by coronary angiography. Data were collected by questionnaire and blood indexes. Brachial-ankle pulse wave velocity (baPWV) was measured using BP-203RPE III network arteriosclerosis detection equipment. Correlation analysis of traditional cardiovascular risk factors and baPWV was performed, and multivariate line regression analysis was conducted to explore the relevant factors for baPWV. A total of 210 patients were included in the final analyses according to the inclusion criteria. Patients with a high baPWV had a lower lymphocyte count than those with a low baPWV (1.2 ± 0.4 vs. 1.4 ± 0.4, P = 0.004). The NLRs of the low and high bvPWV groups were 3.1 ± 1.5 and 4.0 ± 2.1, respectively; no significant difference was observed. The results suggest that there is a positive relationship between baPWV and NLR (r = 0.403, P = 0.005) and neutrophils (r = 0.319, P = 0.016). Multivariate line regression suggested that NLR was positively associated with baPWV (B = 0.372, P = 0.000). The present results indicate that NLR is independently associated with arterial stiffness in patients with ACS. NLR, an inexpensive, easily measurable, widely available biomarker, could be an additional tool for assessing cardiovascular risk in clinical practice.
