Background and Purpose-Little information exists on the epidemiology and patterns of treatment of patients admitted to Brazilian hospitals with stroke. Our objective was to describe the frequency of risk factors, patterns of management, and outcome of patients admitted with stroke in Fortaleza, the fifth largest city in Brazil. Methods-Data were prospectively collected from consecutive patients admitted to 19 hospitals in Fortaleza with a diagnosis of stroke or transient ischemic attack from June 2009 to October 2010. Results-We evaluated 2407 consecutive patients (mean age, 67.7Ϯ14.4 years; 51.8% females). Ischemic stroke was the most frequent subtype (72.9%) followed by intraparenchymal hemorrhage (15.2%), subarachnoid hemorrhage (6.0%), transient ischemic attack (3%), and undetermined stroke (2.9%). The median time from symptoms onset to hospital admission was 12.9 (3.8 -32.5) hours. Hypertension was the most common risk factor. Only 1.1% of the patients with ischemic stroke received thrombolysis. The median time from hospital admission to neuroimaging was 3.4 (1.2-26.5) hours. In-hospital mortality was 20.9% and the frequency of modified Rankin Scale score Յ2 at discharge was less than 30%. Older age, prestroke disability, and having a depressed level of consciousness at admission were independent predictors of poor outcome; conversely, male gender was a predictor of good outcome. Conclusions-The prevalence of stroke risk factors and clinical presentation in our cohort were similar to previous series.Treatment with thrombolysis and functional independency after a stroke admission were infrequent. We also found long delays in hospital admission and in evaluation with neuroimaging and high in-hospital mortality. (Stroke. 2011;42:3341-3346.)
OBJECTIVE:Atrial fibrillation is a common arrhythmia that increases the risk of stroke by four- to five-fold. We aimed to establish a profile of patients with atrial fibrillation from a population of patients admitted with acute ischemic stroke or transient ischemic attack using clinical and echocardiographic findings.METHODS:We evaluated patients consecutively admitted to a tertiary hospital with acute ischemic stroke or transient ischemic attack. Subjects were divided into an original set (admissions from May 2009 to October 2010) and a validation set (admissions from November 2010 to April 2013). The study was designed as a cohort, with clinical and echocardiographic findings compared between patients with and without atrial fibrillation. A multivariable model was built, and independent predictive factors were used to produce a predictive grading score for atrial fibrillation (Acute Stroke AF Score-ASAS).RESULTS:A total of 257 patients were evaluated from May 2009 to October 2010 and included in the original set. Atrial fibrillation was diagnosed in 17.5% of these patients. Significant predictors of atrial fibrillation in the multivariate analysis included age, National Institutes of Health Stroke Scores, and the presence of left atrial enlargement. These predictors were used in the final logistic model. For this model, the area under the receiver operating characteristic curve was 0.79. The score derived from the logistic regression analysis was The model developed from the original data set was then applied to the validation data set, showing the preserved discriminatory ability of the model (c statistic = 0.76).CONCLUSIONS:Our risk score suggests that the individual risk for atrial fibrillation in patients with acute ischemic stroke can be assessed using simple data, including age, National Institutes of Health Stroke Scores at admission, and the presence of left atrial enlargement.
Background: Stroke is the fourth leading killer in the US, the first in Brazil and a leading cause of adult long-term disability in both countries. In spite of widespread recommendation, clinical practice guidelines have had limited effect on changing physician behavior. Recognizing that both knowledge and acceptance of guidelines do not necessarily imply guideline adherence, the American Heart Association/American Stroke Association (AHA/ASA) developed a national stroke quality improvement program, the ‘Get With The Guidelines (GWTG) stroke’. Even though GWTG has produced remarkable results in the US, other countries have not adopted the program. Methods: We compared the stroke treatment quality indicators from a private Brazilian tertiary hospital to those published by the GWTG stroke program. Seven predefined performance measures selected by the GWTG stroke program as targets for stroke quality improvement were evaluated: (1) tissue plasminogen activator use in patients who arrived <2 h from symptom onset; (2) antithrombotic medication use within 48 h of admission; (3) deep vein thrombosis prophylaxis within 48 h of admission for nonambulatory patients; (4) discharge use of antithrombotics; (5) discharge use of anticoagulation for atrial fibrillation; (6) dosing of LDL and treatment for LDL >100 mg/dl in patients meeting the National Cholesterol Education Program Adult Treatment Panel (NCEP) III guidelines, and (7) counseling for smoking cessation. Results: A total of 343 consecutive patients with acute ischemic stroke (70.8%) or transient ischemic attack (29.2%) were evaluated from August 2008 to December 2010. Antithrombotic medication within 48 h was used in 98.5% of the eligible patients and deep vein thrombosis prophylaxis in 100%. A total of 123 patients arrived within 2 h from symptoms onset, 23 were eligible for intravenous thrombolysis and 16 were treated (69.5%). All eligible patients were discharged using antithrombotic medication, and 86.9% of the eligible patients who had atrial fibrillation received anticoagulation. Only 56.1% of the eligible patients were treated according to the NCEP III guidelines. Counseling for smoking cessation was done in 63.6% of the eligible patients. Conclusions: Our study is the first in Brazil and the second outside the US to analyze compliance with the GWTG recommendations. Close attention to a better implementation of these measures may produce an improvement in such results similar to what happened after the full implementation of the program in the US. Whether or not a US disease-based registry such as GWTG can be adopted with success beyond the US is still a matter of debate.
