Abstract
BACKGROUND Identifying reliable prognostic markers is crucial for the effective management of hypertension. The neutrophil-to-lymphocyte ratio (NLR) has emerged as a potential inflammatory marker linked to cardiovascular outcomes. This study aims to investigate the association of NLR with all-cause and cardiovascular mortality among patients with hypertension. METHODS This study analyzed data from 3067 hypertensive adults in the National Health and Nutritional Examination Surveys (NHANES) from 2009 to 2014. Mortality details were obtained from the National Death Index (NDI). Restricted cubic spline (RCS) was deployed to visualize the association of the NLR with mortality risk. Weighted Cox proportional hazards models were employed to assess the independent association of NLR with mortality risk. Time-dependent receiver operating characteristic curve (ROC) analysis was conducted to access the predictive ability of NLR for survival. Mediation analysis was used to explore the indirect impact of NLR on mortality mediated through eGFR. RESULTS Over a median 92.0-months follow-up, 538 deaths occurred, including 114 cardiovascular deaths. RCS analysis revealed a positive association between NLR and both all-cause and cardiovascular mortality. Participants were stratified into higher (> 3.5) and lower (≤ 3.5) NLR groups. Weighted Cox proportional hazards models demonstrated that individuals with higher NLR had a significantly increased risk of all-cause (HR 1.96, 95% confidence interval (CI) 1.52-2.52, p < 0.0001) and cardiovascular mortality (HR 2.33, 95% CI 1.54-3.51, p < 0.0001). Stratified and interaction analysis confirmed the stability of the core results. Notably, eGFR partially mediated the association between NLR and both all-cause and cardiovascular mortality by a 5.4% and 4.7% proportion, respectively. Additionally, the areas under the curve (AUC) of the 3-, 5- and 10- year survival was 0.68, 0.65 and 0.64 for all-cause mortality and 0.68, 0.70 and 0.69 for cardiovascular mortality, respectively. CONCLUSION Elevated NLR independently confers an increased risk for both all-cause and cardiovascular mortality in individuals with hypertension.

[PMID: 37605511 PMCID: PMC10642315 DOI: 10.1002/clc.24131] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/31/2023] [Accepted: 08/10/2023] [Indexed: 08/23/2023] Open
Abstract
BACKGROUND This study aimed to investigate the association between a novel kidney disease index (KDI), which combines information from both estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (uACR), and all-cause and cardiovascular disease (CVD) mortality among individuals with hypertension. METHODS We analyzed data from 19 988 adults with hypertension who participated in the National Health and Nutrition Examination Survey from 1999 to 2018. Mortality outcomes were determined by linking to National Death Index records through December 31, 2019. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals for all-cause and CVD mortality. RESULTS Baseline KDI levels were positively associated with glucose, insulin resistance, hemoglobin A1c, triglycerides, and C-reactive protein (p value for trend <.05). During a follow-up period of 179 859 person-years, a total of 5069 deaths were documented, including 1741 from cardiovascular causes. After multivariable adjustment, each standard deviation increment in KDI level was associated with a 27% increased risk of all-cause mortality and a 31% increased risk of cardiovascular deaths (both p < .05). Further analysis showed a J-shaped association between KDI and mortality, with the risk increasing dramatically when KDI exceeded 0.27. CONCLUSION Elevated KDI levels were significantly associated with increased mortality from all causes and CVD among individuals with hypertension. We recommend routine testing of eGFR and uACR in hypertensive patients, and using KDI as a tool to identify individuals who are most likely to benefit from preventive therapies.

Abstract
OBJECTIVE High levels of D-dimer, a marker of thrombotic events, are associated with poor outcomes in patients with various cardiovascular diseases. However, there has been no research on its prognostic implications in acute severe hypertension. This study investigated the association between D-dimer levels and long-term mortality in patients with severe acute hypertension who visited the emergency department. DESIGN AND METHOD This observational study included patients with acute severe hypertension who visited the emergency department between 2016 and 2019. Acute severe hypertension was defined as a systolic blood pressure ≥ 180 mmHg or a diastolic blood pressure ≥ 100 mmHg. Among the 10,219 patients, 4,127 who underwent D-dimer assay were analyzed. The patients were categorized into tertiles based on their D-dimer levels at the time of emergency department admission. RESULTS Among the 4,127 patients with acute severe hypertension, 3.1% in the first (lowest) tertile, 17.0% in the second tertile, and 43.2% in the third (highest) tertile died within 3 years. After the adjustment for confounding variables, the third tertile of the D-dimer group (hazard ratio, 6.440; 95% confidence interval, 4.628-8.961) and the second tertile of the D-dimer group (hazard ratio, 2.847; 95% confidence interval, 2.037-3.978) had a significantly higher risk of all-cause mortality over 3 years than the first tertile of the D-dimer group. CONCLUSIONS D-dimer may be a useful marker for identifying the risk of mortality among patients with acute severe hypertension who visit the emergency department.

Abstract
BACKGROUND Microscopic hematuria is associated with increased risk of developing chronic kidney function impairment and even death. However, data on the long-term mortality risk associated with microscopic hematuria among patients with hypertensive crisis are scarce. We hypothesized that microscopic hematuria at initial presentation in patients with hypertensive crisis would be associated with increased long-term mortality. METHODS This retrospective study included patients admitted to the emergency department between 2016 and 2019 for hypertensive crisis (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg). Microscopic hematuria was defined as ≥ 3 red blood cells per high-power field on microscopic evaluation of urine. RESULTS Among 3595 patients, 1359 (37.8%) had microscopic hematuria. The 3-year all-cause mortality in patients with and without microscopic hematuria was 25.5% and 16.3%, respectively. After adjusting for confounding variables, patients with microscopic hematuria (adjusted HR, 1.30; 95% CI 1.10-1.54) showed a significantly higher risk of 3-year all-cause mortality than patients without microscopic hematuria. In a subgroup analysis based on the presence of proteinuria, microscopic hematuria was a significant predictor of all-cause mortality in patients without proteinuria (adjusted HR, 1.61; 95% CI 1.28-2.03) but not in patients with proteinuria. CONCLUSION Microscopic hematuria was a significant predictor of all-cause mortality in patients with hypertensive crisis. Our study suggests that microscopic hematuria can be a useful prognostic marker and may permit early detection of patients with an increased risk of death. Clinicians in the emergency department should consider screening for kidney function using urine analysis during the initial assessment of patients with hypertensive crisis.

Abstract
B-type natriuretic peptide (BNP) is a well-established prognostic factor for cardiovascular disorders. However, the association between BNP levels and mortality in patients with acute severe hypertension remains unclear. This study aimed to investigate the association between BNP levels and long-term mortality in patients with acute severe hypertension visiting the emergency department (ED). This retrospective study included patients aged ≥ 18 years who were admitted to the ED between 2016 and 2019 with acute severe hypertension (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 100 mmHg). Patients were categorized into tertiles according to BNP levels upon admission to the ED. Of the 3099 patients with acute severe hypertension, 6.4% in the first (lowest) tertile, 24.8% in the second tertile, and 44.4% in the third (highest) tertile of BNP died within 3-years. After adjusting for clinically relevant variables, patients in the second tertile of BNP (adjusted hazard ratio [HR], 2.64; 95% confidence interval [CI], 1.96-3.55), and patients in the third tertile of BNP (adjusted HR 4.18; 95% CI, 3.09-5.64) had a significantly higher risk of 3-year all-cause mortality than those in the first tertile of BNP. Therefore, BNP may be valuable for the initial assessment to identify high-risk patients among those with acute severe hypertension.

Abstract
BACKGROUND Anaemia is frequent in patients with cardiovascular disease and is significantly associated with poor prognosis. However, the prognostic significance of anaemia in hypertensive crisis remains unknown. We conducted this study to determine whether anaemia is a risk factor for all-cause mortality in patients with hypertensive crisis visiting the emergency department (ED). METHODS This retrospective study included patients who visited the ED between 2016 and 2019 for hypertensive crisis, which was defined as systolic blood pressure ≥180 mmHg or diastolic blood pressure ≥110 mmHg. A total of 5,512 patients whose serum haemoglobin levels were checked were included in this study and were classified into three groups according to their serum haemoglobin levels at admission to the ED: moderate/severe anaemia (haemoglobin <11 g/dL), mild anaemia (haemoglobin 11 to <13 g/dL in men and 11 to <12 g/dL in women), and non-anaemia (haemoglobin ≥13 g/dL in men and ≥12 g/dL in women). RESULTS Among 5,512 patients, 665 (12.1%) and 668 (12.1%) were classified into the moderate/severe anaemia and mild anaemia groups, respectively. The three-year all-cause mortality rates in the moderate/severe anaemia, mild anaemia, and non-anaemia groups were 46.0, 29.2, and 12.0%, respectively. After accounting for relevant covariates, patients with moderate/severe anaemia group (hazard ratio [HR], 2.15; 95% confidence interval [CI], 1.75-2.64) and mild anaemia group (HR, 1.32; 95% CI, 1.07-1.63) had a higher risk of 3-year all-cause mortality than the non-anaemia group. CONCLUSION Anaemia is independently associated with 3-year all-cause mortality in patients with hypertensive crisis. A comprehensive therapeutic approach through more in-depth examination and close follow up are required for patients with hypertensive crisis with anaemia.KEY MESSAGESAnaemia is independently associated with 3-year all-cause mortality in patients with hypertensive crisis.A comprehensive therapeutic approach through more in-depth examination and close follow up are required for patients with hypertensive crisis with anaemia.
