Background:
and Purpose: Blood pressure (BP) control is strongly recommended, but BP control rate has not been well studied in patients with stroke. We evaluated the BP control rate with fimasartan-based antihypertensive therapy initiated in patients with recent cerebral ischemia.
Methods:
This multicenter, prospective, single-arm trial involved 27 centers in South Korea. Key inclusion criteria were recent cerebral ischemia within 90 days and high BP [systolic blood pressure (SBP) >140 mm Hg or diastolic blood pressure (DBP) >90 mm Hg]. BP lowering was initiated with fimasartan. BP management during the follow-up was at the discretion of the responsible investigators. The primary endpoint was the target BP goal achievement rate (<140/90 mm Hg) at 24 weeks. Key secondary endpoints included achieved BP and BP changes at each visit, and clinical events (ClinicalTrials.gov Identifier: NCT03231293).
Results:
Of 1,035 patients enrolled, 1,026 were included in the safety analysis, and 951 in the efficacy analysis. Their mean age was 64.1 years, 33% were female, the median time interval from onset to enrollment was 10 days, and the baseline SBP and DBP were 162.3±16.0 and 92.2±12.4 mm Hg (mean±SD). During the study period, 55.5% of patients were maintained on fimasartan monotherapy, and 44.5% received antihypertensive therapies other than fimasartan monotherapy at at least one visit. The target BP goal achievement rate at 24-week was 67.3% (48.6% at 4-week and 61.4% at 12-week). The mean BP was 139.0/81.8±18.3/11.7, 133.8/79.2±16.4/11.0, and 132.8/78.5±15.6/10.9 mm Hg at 4-, 12-, and 24-week. The treatment-emergent adverse event rate was 5.4%, including one serious adverse event.
Conclusions
Fimasartan-based BP lowering achieved the target BP in two-thirds of patients at 24 weeks, and was generally well tolerated.

Objective:
Early identification of dysphagia after stroke helps in preventing aspiration pneumonia. However, data are limited regarding the effectiveness of formal dysphagia screening for reducing the risk of aspiration pneumonia.The current study evaluates the effectiveness of formal dysphagia screening in stroke patients, to prevent future episodes of aspiration pneumonia.
Methods:
The stroke registry of a tertiary hospital was retrospectively reviewed. We compared clinical variables and the incidence of aspiration pneumonia of patients hospitalized between 2014 and 2015 after formal screening was implemented, and patients hospitalized in 2011 when no established dysphagia screening protocol was in place.Additionally, we identified the incidence of pneumonia according to stroke severity, and evaluated the association with results obtained for incidence of pneumonia and dysphagia screening.
Results:
A total of 2,902 patients were identified to have suffered acute stroke (2,018 who underwent formal dysphagia screening; 884 without screening). Patients with formal dysphagia screening developed pneumonia less frequently than patients not administered screening (1.3% with formal screening vs. 3.4% no formal screening, P<0.001).Pneumonia was significantly lower in patients with moderate and severe stroke who underwent formal dysphagia screening. Furthermore, failure of the dysphagia screening test, presentation with severe dysarthria, and conditions where dysarthria could not be evaluated, were independent predictors of pneumonia among patients who underwent formal screening.
Conclusion
Our findings demonstrate the association of formal dysphagia screening with reduced risk of poststroke aspiration pneumonia, and indicates the efficacy of the procedure in identifying patients at higher risk of contracting pneumonia.

Background/Aims:
Although statins are widely used to reduce the risk of cardiovascular disease (CVD) including stroke and myocardial infarction (MI), it is reported that statin use increases the incidence of herpes zoster (HZ) that is associated with increased risk of CVD. So, we evaluated the mediation effect of HZ caused by statin use on CVD.
Methods:
We analyzed a prospective cohort from the National Health Insurance Service-database of South Korea. All individuals received a medical check-up and were followed-up from 2002 to 2013.
Results:
A total of 275,382 individuals > 40 years old were followed up for 11 years from 2003. Of these, 11,415 people (4%) were classified as statin users and 263,967 (96%) as non-statin users. Those who used statins had significantly lower risks of cardiovascular events, stroke, and MI compared with non-statin users; the adjusted hazard ratios in the multivariate analysis were 0.90 (95% confidence interval [CI], 0.82 to 0.98), 0.88 (95% CI, 0.80 to 0.98), and 0.91 (95% CI, 0.79 to 1.07), respectively. When we calculated the mediating effect of cardiovascular events by statin use through HZ, 11.6% of the total beneficial effect of cardiovascular events by statin use was mitigated through the occurrence of HZ caused by statin use. This mediating effect was higher in the younger age group (< 60 years).
Conclusions
This study showed that statin use reduced CVD by 10%, but the protective effect of statin use against CVD was mitigated by approximately 10% through the development of HZ caused by statin use.

Ischemic stroke and myocardial infarction share common risk factors and pathophysiologic mechanisms. Unrecognized coronary artery disease typically occurs in 20-30% of patients with ischemic stroke, and its presence helps to predict the outcome. Coronary artery disease is also an important cause of morbidity and mortality in patients with ischemic stroke. Therefore, applying a screening test for asymptomatic coronary artery disease may be considered in ischemic stroke patients who have a high cardiovascular risk profile. Coronary computed tomography (CT) angiography, myocardial perfusion imaging, or stress echocardiography can be used as a screening test. Coronary CT angiography is recommended in the absence of allergy to contrast media and renal insufficiency.

The purpose of this clinical practice guideline (CPG) is to provide current and comprehensive recommendations for the medical and surgical management of primary intracerebral hemorrhage (ICH). Since the release of the first Korean CPGs for stroke, evidence has been accumulated in the management of ICH, such as intracranial pressure control and minimally invasive surgery, and it needs to be reflected in the updated version. The Quality Control Committee at the Korean Society of cerebrovascular Surgeons and the Writing Group at the Clinical Research Center for Stroke (CRCS) systematically reviewed relevant literature and major published guidelines between June 2007 and June 2013. Based on the published evidence, recommendations were synthesized, and the level of evidence and the grade of the recommendation were determined using the methods adapted from CRCS. A draft guideline was scrutinized by expert peer reviewers and also discussed at an expert consensus meeting until final agreement was achieved. CPGs based on scientific evidence are presented for the medical and surgical management of patients presenting with primary ICH. This CPG describes the current pertinent recommendations and suggests Korean recommendations for the medical and surgical management of a patient with primary ICH.

Extracranial carotid stenosis is a well-established, modifiable risk factor for stroke. Asymptomatic extracranial carotid stenosis is increasingly being detected due to the introduction of less-invasive and more-sensitive advanced diagnostic technologies. For severe asymptomatic stenosis, earlier pivotal clinical trials demonstrated the benefit of carotid endarterectomy over the best medical therapy. Since then, great advances have been made in interventional and medical therapies as well as surgical techniques. The first edition of the Korean Stroke Clinical Practice Guidelines for primary stroke prevention for the management of asymptomatic carotid stenosis reflected evidences published before June 2007. After the publication of the first edition, several major clinical trials and observational studies have been published, and major guidelines updated their recommendation. Accordingly, the writing group of Korean Stroke Clinical Practice Guidelines (CPG) decided to provide timely updated evidence-based recommendations. The Korean Stroke CPG writing committee has searched and reviewed literatures related to the management of asymptomatic carotid stenosis including published guidelines, meta-analyses, randomized clinical trials, and nonrandomized studies published between June 2007 and Feb 2011. We summarized the new evidences and revised our recommendations. Key changes in the updated guidelines are the benefit of intensive medical therapy and further evidence of carotid artery stenting as an alternative to carotid endarterectomy. The current updated guidelines underwent extensive peer review by experts from the Korean Stroke Society, Korean Society of Intravascular Neurosurgery, Korean Society of Interventional Neuroradiology, Korean Society of Cerebrovascular Surgery, and Korean Neurological Association. New evidences will be continuously reflected in future updated guidelines.

BACKGROUND: This scientific statement is intended to provide a systematic review of new evidences in dyslipidemia and inflammation for primary stroke prevention. METHODS: Using a structured literature search, we identified major observational studies, clinical trials, meta-analyses, and updated major guidelines published between July 2007 and November 2010. In addition to the brief summary of earlier evidences employed in the first edition of Korean clinical practice guideline for primary prevention of stroke, we summarized the newly identified evidences. RESULTS: For dyslipidemia, observational studies further support a strong association between ischemic stroke and high total and low-density lipoprotein cholesterol and low high-density lipoprotein cholesterol. Two clinical trials and 6 meta-analyses confirm statin efficacy for primary prevention of stroke in high risk patients. Efficacy of other lipid-lowering agents is not established. For inflammation, inflammatory markers might help to identify patients having high risk for stroke or cardiovascular event and to decide whether statin therapy is indicated, but its usefulness for broad population needs to be confirmed. CONCLUSIONS: Writing committee will continue to keep an eye on upcoming evidences to timely update the guideline for primary stroke prevention in dyslipidemia and inflammation.

Writing Committee of Korean clinical practice guidelines for secondary prevention of stroke has reviewed recent randomized controlled trials of cilostazol published after the first edition of Korean clinical practice guidelines that considered evidences published before June 2007. Two clinical trials and 1 meta-analysis which compared cilostazol directly with aspirin in the prevention of stroke in patients with cerebral infarction or transient ischemic attack (TIA) were identified and included for the current guideline update. Review of findings indicates that cilostazol as compared to aspirin achieved a greater reduction of stroke as well as composite vascular events of stroke, myocardial infarction, and vascular death. For safety, cilostazol was associated with fewer major bleeding events than aspirin. Accordingly, new recommendations for cilostazol are made for prevention of stroke in the setting of noncardioembolic stroke or TIA. Changes in the guidelines necessitated by new evidences will be continuously reflected in future guidelines.
