ABSTRACT
Objective To investigate the predictive value of D-dimer for early neurological deteriora- tion (END) in patients with acute ischemic stroke. Methods Patients with acute ischemic stroke admitted to the Department of Neurology, the Second People ' s Hospital of Shenzhen between January 2015 and December 2017 were enrolled retrospectively. END was defined as an increase ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score or an increase ≥1 in the motor function score within 7 days after admission compared with the baseline score. Demographics, baseline clinical data, and primary treatment options during hospitalization were compared between the END group and the non-END groups. Multivariate logistic regression analysis was used to determine the independent risk factors for END. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of D-dimer for END. Results A total of 625 patients were enrolled in the study, including 40 in the END group (including 3 deaths) and 585 in the non-END group. The mean hospital stay, international normalized ratio, D-dimer, uric acid, NIHSS score and modified Rankin Scale (mRS) score at admission, and the proportion of patients with complete anterior circulation infarction, large atherosclerotic stroke, and pulmonary infection were significantly higher than those in the non-END group (all P < 0. 05). There was no significant difference in the proportion of patients receiving thrombolysis, antiplatelet,anticoagulation, and statins between the two groups. ROC curve analysis showed that the area under the curve of D-dimer predicting END was 0. 810 (95％ confidence interval [CI] 0. 736-0. 884; P < 0. 001); the optimal cut-off value was 2. 35 mg/L, and the sensitivity and specificity were 54. 74％ and 96. 13％ respectively. Multivariate logistic regression analysis showed that large atherosclerotic stroke (odds ratio [OR] 1. 115, 95％ CI 1. 005-1. 390; P = 0. 003 ), D-dimer ≥2. 35 mg/L (OR 1. 055,95％ CI 1. 012-1. 150; P = 0. 001 ), NIHSS score at admission (OR 1. 191, 95％ CI 1. 006-1. 410; P <0. 001), mRS score > 1 at admission (OR 1. 755, 95％ CI 1. 139-3. 656; P = 0. 037 ), and pulmonary infection (OR 2. 598, 95％ CI 1. 132-3. 081; P = 0. 012) were the independent risk factors for END in patients with acute ischemic stroke. Conclusion D-dimer ≥2. 35 mg/L at admission has higher predictive value for END in patients with acute ischemic stroke.
ABSTRACT
Objective To evaluate the predictive value of HEART and GRACE scores for risk stratification and 30-day major adverse cardiovascular events (MACE) in patients with acute chest pain in emergency department.Methods This is a prospective observational study.Patients with acute chest pain aged 18 years or older who were first diagnosed in our emergency department were enrolled from January 1,2016 to September 1,2017.The clinical data were collected,and HEART and GRACE scores were calculated.All causes of MACE in each patient were followed up for 30 days.Results This study included 1004 patients with acute chest pain for analysis.Finally this study enrolled 600 patients with an age range of 20-98 years (mean 63.28±15.47 years),351 males (58.5％) and 249 females (41.5％).The age,past history (smoking,coronary heart disease and diabetes),GRACE score and HEART score in MACE patients were significantly higher than those in non-MACE patients (P＜0.05).The area under the ROC curve of HEART and GRACE scores were 0.817 (95％ CI 0.771-0.863) and 0.739 (95％ CI:0.687-0.791),respectively.The percent of patients with 30-day MACE with GRACE score and HEART score were 6.2％ vs 4.1％ in low-risk stratification,19.7％ vs 15.1％ in medium-risk stratification,and 35.1％ vs 56.5％ in high-risk stratification,respectively.Conclusions The HEART score is superior to the GRACE score in predicting 30-day MACE in patients with acute chest pain in emergency department.
ABSTRACT
Objective To explore the HEART risk score in predicting 30-day major adverse cardiovascu-lar events (MACE)for the patients presenting to Emergency Department (ED) with acute chest pain. Methods Patients presented in our ED with acute chest pain were enrolled from January,2016 to April,2016. All cause MACE of each patient were followed up at 30 days by Health insurance information management System and call . Results Total 209 patients were enrolled(mean age 65.28 ± 16.85 years;52.63%male). The age,hypertension, ratio of ACS,SpO2,in-patient number HEART score in MACE subject were significantly higher than that in non MACE patients(P<0.05). The blood pressure at admission of MACE patients was significantly decrease than that in non MACE patients(P<0.05). The MACE within 30 days was 5.74%. The respective areas under the curve (AUC)for 30-day MACE(95% CI)was 0.908(0.846 ~ 0.974). The percent of patients with 30-day MACE with HEART scores between 0% and 3,4 ~ 6,and 7 ~ 10 was 0%,2.5%,and 27%,respectively. Conclusion HEART score can be simple,rapid and accurate prediction of emergency department of patients with acute chest pain within 30 days of MACE,effective elimination of low-risk patients with MACE,it plays a very important role for disease assessment and diagnosis and treatment process in emergency department.
ABSTRACT
ObjectiveTo investigate the clinical characteristics of the inpatients suffering from dengue fever in order to provide references for better diagnosis and treatment.Methods The clinical data of 158 dengue fever patients admitted to the First Affiliated Hospital of Sun Yat-Sen University from July 23rd to October 31st, 2014 during the 2014 epidemic in Guangzhou area were retrospectively analyzed, including general clinical manifestations, conventional examinations, pathogenesis, and prognosis.Results The mean age of the 158 patients was (56±20) years, with half of them over 60 years old (79 cases). Among them, 94 (59.49%) were male.① The common manifestations included fever (100%), headache (70.89%), myalgia/bone soreness (62.03%), and skin rash (54.43%). Bleeding and plasma leakage were found in 25.95% and 14.56% of the patients respectively.② Laboratory examination:leucopenia (75.32%) and thrombocytopenia (77.85%) were found, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated in 57.59% and 77.85% of the patients respectively. However, elevation of blood hematocrit was rare (1.27%).③ It was found that in the acute phase (0 - 5 days of the onset), serum dengue virus antibody IgM (DF-IgM) was positive in 63.54% of the patients (61/96), and 92.62% (113/122) of patients were dengue virus RNA (DENA-RNA) positive.④ The rate of comorbidity in this study was 55.06% (87/158), including hypertension (27.22%) and type 2 diabetes (15.82%), which were the two most common co-morbidities.⑤ All the patients were given supportive therapy to prevent complications. They were also isolated for more than 5 days after onset, and at least for 24 hours after subsidence of fever in addition.⑥ The criteria for the diagnosis of severe dengue were fulfilled in 18 patients (11.39%). One patient died of massive hemorrhage from gastro-intestinal tract, and 1 patient voluntarily left hospital with untreated multiple organ dysfunction syndrome (MODS). Another 2 patients of dengue fever died from primary cardio-cerebrovascular disease, and the remaining 154 patients (97.47%) fully recovered with supportive therapy and complication prevention measures.Conclusions The clinical manifestations of inpatients with dengue fever in this study were typical, and they manifested a higher incidence of severe illness. DENA-RNA could be a sensitive indicator for early pathogenic diagnosis. With symptomatic and supportive therapy, most patients had a good outcome. However, early diagnosis and clinical interventions of severe dengue still need further studies.
