ABSTRACT
Objective:To investigate the clinical characteristics and outcomes in patients with wake-up stroke.Methods:From January 2019 to December 2019, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Huizhou Municipal Central Hospital were enrolled retrospectively. The modified Rankin Scale was used to evaluate the outcome of patients at 90 d after the onset. 0 to 2 was defined as a good outcome, and >2 was defined as a poor outcome. Multivariate logistic regression analysis was used to determine the factors affecting the poor outcome of patients with wake-up stroke. Results:A total of 356 patients with acute ischemic stroke were enrolled, including 97 (27.2%) wake-up stroke, and 259 (72.8%) non-wake-up stroke. The National Institutes of Health Stroke Scale (NIHSS) score at admission and the proportion of patients with atrial fibrillation, moderate to severe stroke and cardiogenic embolism in the wake-up stroke group were significantly higher than those of the non-wake-up stroke group, and the proportion of patients with small artery occlusion was significantly lower than that in the non-wake-up stroke group (all P<0.05). Moreover, the proportion of patients with poor outcome in the wake-up stroke group was significantly higher than that in the non-wake-up stroke group (36.1% vs. 24.7%; χ2=4.546, P=0.033). In the wake-up stroke group, 62 patients (63.9%) had a good outcome, and 35 (36.1%) had a poor outcome. The NIHSS score at admission and the proportion of patients with atrial fibrillation and moderate to severe stroke in the subgroup with poor outcome were significantly higher than those in the subgroup with good outcome, and the proportion of patients receiving intravenous thrombolysis and mechanical thrombectomy was significantly lower than those in the good outcome subgroup (all P<0.05). Multivariate logistic regression analysis showed that moderate to severe stroke (odds ratio [ OR] 6.674, 95% confidence interval [ CI] 2.223-20.034; P=0.001) was independently associated with the poor outcome in patients with wake-up stroke, while intravenous thrombolysis ( OR 0.102, 95% CI 0.017-0.630; P=0.014) and endovascular mechanical thrombectomy ( OR 0.108, 95% CI 0.023-0.506; P=0.005) were independently associated with the good outcome of patients with wake-up stroke. Conclusions:In patients with wake-up stroke, the proportion of cardioembolism is higher, the clinical symptoms are more serious and the incidence of poor outcome is higher. The severity of stroke at admission is associated with poor short-term outcome, and intravenous thrombolysis and endovascular mechanical thrombectomy can improve the outcome in patients with wake-up stroke.
ABSTRACT
Objective:To investigate the predictive value of STAF (score for the targeting of atrial fibrillation) score for paroxysmal atrial fibrillation (PAF) in patients with recurrent acute ischemic stroke.Methods:Consecutive patients with recurrent acute ischemic stroke hospitalized in the Department of Neurology, Huizhou Municipal Central Hospital from January 2014 to January 2020 were enrolled retrospectively. All patients were divided into a sinus rhythm (SR) group and a PAF group. PAF was defined as no PAF during the last stroke hospitalization or after discharge, and PAF was found by routine ECG, ambulatory ECG or long-term ECG monitoring after this recurrent acute ischemic stroke. Multivariate logistic regression analysis was used to evaluate the independent related factors of PAF in patients with recurrent acute ischemic stroke. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of STAF for PAF in patients with recurrent acute ischemic stroke. Results:A total of 234 patients with recurrent acute ischemic stroke were enrolled, including 174 males (74.4%), aged 67.15±10.63 years, and 199 (85.0%) in the SR group and 35 (15.0%) in the PAF group. Univariate analysis showed that the proportion of patients in age >62 years old (94.3% vs. 63.8%; χ2=12.777, P<0.001) and left atrial enlargement (54.3% vs. 11.1%; χ2=40.379, P<0.001) of the PAF group was significantly higher than those of the SR group. Multivariate logistic regression analysis showed that age (odd ratio [ OR] 1.071, 95% confidence interval [ CI] 1.028-1.114; P=0.001) or age >62 years ( OR 17.512, 95% CI 2.881-106.453; P=0.002), left atrial enlargement ( OR 17.511, 95% CI 6.298-48.687; P<0.001), absence of vascular etiology ( OR 8.562, 95% CI 2.534-28.923; P=0.001), STAF score ( OR 2.715, 95% CI 1.969-3.744; P<0.001) and STAF score ≥5 ( OR 12.714, 95% CI 5.636-28.681; P<0.001) were independently associated with PAF. ROC curve analysis showed that the area under the curve of STAF for predicting PAF in patients with recurrent acute ischemic stroke was 0.848 (95% CI 0.779-0.917), and the sensitivity and specificity of STAF ≥5 for predicting PAF were 58.1% and 89.4%, respectively; the area under the curve for predicting PAF in patients with recurrent ischemic stroke of undetermined cause was 0.809 (95% CI 0.663-0.956), and the sensitivity and specificity of STAF ≥5 for predicting PAF were 53.8% and 91.3%, respectively. Conclusions:PAF is likely to exist in patients with recurrent acute ischemic stroke and aged >62 years, left atrial enlargement and absence of vascular etiology. STAF has medium predictive value for PAF in patients with recurrent acute ischemic stroke, but the sensitivity is not high.
ABSTRACT
Objective To investigate the risk factors of intracranial hemorrhagic (ICH) transformation within 14-days in acute cerebral infarction with non-valvular atrial fibrillation (NVAF) patients. Methods CT and/or MRI scans of the head were conducted within 14 days on patients with NVAF acute cerebral infarction who admitted to the Department of Neurology, Huizhou Municipal Central Hospital between January 2015 to March 2018. The baseline scan data were reviewed to determine whether ICH conversion occurred. Comparable risk assessment were based on stratification scores using HAS-BLED, ASPECTS, and pc-ASPECTS. Results There were 150 cases of acute cerebral infarction with NVAF, 126 patients were eligible for the analysis, with an ICH conversion rate of 27.0% (34/126). The following four risk factors were statistically significant among the ICH and non-ICH transformation groups: ①systolic blood pressure (SBP) >160 mmHg or diastolic blood pressure (DBP) >100 mmHg post-cerebral infarction, ②Severe cerebral infarction, progressing stroke, ③ASPECTS (pc-ASPECTS) score ≤7 points, and ④ HAS-BLED score ≥3 points (P<0.05). Conclusion Approximately 1/3 of NVAF acute cerebral infarction patients experience an ICH transformation within 14 days of their episode. The following indicators are independent risk factors of ICH transformation: SBP >160mmHg or DBP >100mmHg after cerebral infarction, severe cerebral infarction, progressing stroke, ASPECTS (pc-ASPECTS)≤7 points, and HAS-BLED score≥3 points.
ABSTRACT
Objective To find out whether inpatients with acute ischaemic stroke and atrial fibrillation (AF) have higher rate of renal dysfunction than without AF,and analyze risk factors associated with renal dysfunction.Method 374 patients with acute ischaemic stroke and AF were enrolled,which cases have complete data.500 patients were randomly selected as the non-AF group.To compare the prevalence of renal dysfunction [eGFR ＜ 60 mL/(min· 1.73 m2)] of two groups.Non-conditional Logistic regression analysis was used to detemmine the factors associated with renal dysfunction.Results 374 patients in AF group,114 (30.5％) were renal dysfunction;500 patients in non-AF group,75 (15％) were renal dysfunction (P =0.000,OR =2.485).The eGFR of AF and non-AF group was (77.75 ± 39.89) mL/(min· 1.73 m2) and (96.93±39.14) mL/(min · 1.73 m2).In Logis tic regression analysis,heart dysfunction (OR =2.057),hypertension (OR =1.826),diabetes (OR =1.897),hypevuricemia (OR =3.161) were found to be associated with renal dysfunction.Conclusions Adult patients with acute ischaemic stroke and AF have a higher rate of renal dysfunction than acute ischaemic stroke without AF.Heart dysfunction,hypertension,diabetes,hyperuricemia were factors associated with renal dysfunction.
ABSTRACT
Objectives The aim of this study was to study the relationship between silent cerebral ischemia (SCI) and mild cognitive impairment(MCI)in inpatients with nonvalvula atrial fibrillation (NAF) and those with sinus rhythm (SR) older than sixty. Methods Ninety-eight inpatients were enrolled from November 2014 to November 2015 in Hui?zhou Municipal Central Hospital: 45 patients with NAF and 53 with SR. All general clinical data was collected. The Montreal Cognitive Assessment (MoCA) and brain MRI were used to assess the cognitive performance of patients within 1 weeks of admission. Results The MoCA scores were lower in patients with NAF than in those with SR[16(10,20) vs. 20 (15,23),P=0.006]. At least one foci of SCI was present in patients 80%with NAF and 52.8%with SR (NAF vs. SR, P=0.018).The rates of SCIs in the cortex/subcortex were higher in the NAF group than in the SR group (25.2%vs. 12.4%, P=0.017). Multivariate analysis showed that MoCA score were related to the degree of education in NAF patients and were related to age and education level in SR patients. Conclusions NAF is an independent risk factor for cognitive impair?ment in NAF patient and associated with the SCI present. Educational level is a factor affecting the cognitive function with elderly patients.
ABSTRACT
Objective To explore the role of hypothermia in curing patients with acute cerebral infarction. Methods 40 patients with final diagnosis of acute cerebral infarction in our department from 2007-3 ～ 2009-1 were selected and randomly divided into hypothermia group and normathermia group. Both groups were treated with the same approach except the hypothermal intervention in hypothermia group. Prognosis,infarct size and the rate of revas-cularization were compared between the groups after 1 month following up. Results When compared with the normathermia group,the hypothermia group had better prognosis and less infarct size after treating,but statistical significance could not find in two groups in the rate of revascularization. Conclusion Under a series of mechanism,hypothermia could grow down the local infarct size and make important sense to improve the prognosis of patients with acute cerebral infarction.
ABSTRACT
Objective To explore the role of transcranial doppler(TCD) on therapeutic effects of intravenous thrombolysis for patients with acute cerebral infarction by using transcranial doppler to make dynamic detection pre and pro-intravenous thrombolysis. Methods 60 patients with the final diagnosis of acute cerebral infarction were selected according to the inclusion criteria and exclusion criteria standard promissory. Recombinant tissue type plasminogen activator as the intravenous thrombolysis agent was used 4.5h later onset of the disease in all these cases, and TCD monitoring was preformed to understand the sitiations of the target blood vessels pre and pro-thrombloysis treatment on the 6,12 hours and 24 hours,the 2st day and the 7th day,all the data offered by which was used to adjust the treatment protocois of antiplatelet and anticoagulant therapy after 24 hours. All patients were followed up for 3 months,among whom prognostic evaluation, situations of revascularization was carried out as well as the complications of secondary intracranial hemorrhages and reocclusion basing on the neurologic impairment Score and the Thrombolysis in Brain lschemia(TIBI) respectively. Results No patient was dead after following-up for 3 months and 17 cases with basi- healing(28.3%) ,20 cases with excellence(33.3%), 16 cases got better(26.7%) ,3 cases with inefficiency (5.0%), and 4 cases became deterioration (6.7%). According to the Thrombolysis in Brain lschemia( TIBI), 22 cases got 4-5 level( 36.7 %), 31 cases with 2-3 level ( 51.7% ), and 7 cases got 0-1 level ( 11.6 % ). Among all these cases ,4 cases were found with secondary intracranial hemorrhages (6. 7% ) and 5 cases with reocclusion ( 8.3% ) Conclusion Dynamic detection with transcranial doppler pre and pro-intravenous thrombolysis could improve the therapeutic effect on patients with acute cerebral infarction, and reduce its complication, which is important for the clinical wrok and deserving consulting.
ABSTRACT
Objective To explore the influence of diastolic blood pressure to prognosis of patients with acute cerebral infarction. Methods Clinical data of 200 patients with acute cerebral infarction were retrospectively reviewed Patients were divided into three groups based on diastolic blood pressure(DBP)when admission;hypotensive group(DBP＜70 mm Hg),normotensive group(DBP;70-90 mm Hg)and hypertensive group(DBP ＞ 90 mm Hg).Constituent ratio of patients with different level of DBP were calculated and prognosis were compared among the three groups. Results Of all the total patients with acute cerebral infarction,8%(16)presented with hypotension,12%(24)were normotensive and 80%(160)were hypertensive.In the hypotensive group,50%(8)patients died as compared to 17%(4)in normotensive group and 38%(60)in hypertensive group,among all the cases,patients with bypotension or hypertension seemed like to have a higher mortality than normotensive group(P=0.037;x2=3.993,P=0.046),and there was no significant diffenence between two group with hypotension or hypertension. Conclusion The patients with diastolic blood pressure of less than 70 mm Hg or more than 90 mm Hg were predictors of poor outcome.
ABSTRACT
Objective To explore the early diagnosis of lower extremity deep venous thrombosis (LDVT)and evaluate the therapeutic effect of anticoagulant therapy in hospitalized patients with acute ischemic stroke. Methods According to Wells model for suspecting lower extremity deep venous thrombosis,patients with suspected LDVT were confirmed by compression ultrasonography. If the patients diagnosed with LDVT had no contraindications to anticoagulant therapy,they were treated with low molecular weight heparin(LMWH)subcutaneous injection and oral warfarin at the same time.The dosage of oral warfarin was determined by Roberts'age adjusted warfarin loading protocol.LMWH was stopped when the patients'international normalized ratio(INR)was 2.0～3.0 for two consecutive days. Results From January 2003 to August 2007,2067 cases with acute ischemic stroke were admitted to the department of neurology in Huizhou Municipal Central Hospital including 18 cases with LDVT and the incidence was 0.9%.The patients with LDVT all had paralytic extremities including 13 left legs and 5 right legs with deep vein thrombosis.All the 18 cases were treated by anticoagulant including 17 cases with oral warfarin treatment for 3 months.Symptoms in all LDVT patients were eliminated.12 cases had been observed for one year and 5 cases for three months after they stopped taking warfatin.There were no patients with pulmonary thromboembolism and LDVT recurrence. Conclusions By using Wells model for suspecting LDVT,patients with acute ischemic stroke-complicated LDVT can be timely diagnosed.The goal of prompt and enough anticoagulant can be achieved according to Roberts'age adjusted warfarin loading protocol.Because of racial difference,population difference and other unknown factors,the incidence of acute ischemic stroke patients with complicated LDVT is much lower in Huizhou.It suggests that it should be unnecessary to use LMWH in patients with acute ischemic stroke to prevent LDVT in Huizhou.
ABSTRACT
Objective To evaluate the effect of omeprazole in preventing treatment of hypertensive cerebral hemorrhage with stress ulcer bleeding. Methods A total of 100 patients with hypertensive cerebral hemorrhage were treated with conventional therapy including dehydration, antihypertensive and supporting treatment. The patients were randomly divided into omeprazole group(n=50) and control group( n = 50). The control group received conventional therapyonly, while the omeprazole group received additional omeprazole 40mg, iv, qd, for 14d. Results Omeprazole group stress ulcer 6 eaess(12.0% ) was significantly lower than the control group 12 cases(24.0% );two groups stress ulcer incidence of severity are increasing with the increase of the disease; the mortalities of cerbral hemorrhage were 6.0 % in the omeprazole group and 16.0 % in the control group and the difference had significant meaning(P＞0.05). Conclusion Omeprazole has significant beneficial effect in preventing upper gastrointestinal hemorrhage after hypertensive cerebral hemorrhage.
