Background and Purpose. Stroke is a leading cause of death and disability, with ischemic stroke as the highest prevalent cases in Indonesia. Ischemic stroke can be classified further into five subtypes according to TOAST classification. Numerous studies have revealed that stroke risk factor has variable correlation with different stroke subtype. Currently, there is no data regarding this phenomenon in Indonesia. The aim of study is to identify characteristic of ischemic stroke subtypes and the risk factors in TOAST classification. Methods. A retrospective, cross-sectional study of patients diagnosed with ischemic stroke at Cipto Mangunkusumo Hospital from January till December 2016. Demographic data, ischemic stroke subtypes, risk factors, and other relevant data were documented. Bivariate and multivariate analysis was done using SPSS 23. Results. 235 recorded data patients were included. Large artery atherosclerosis (LAA) was the most prevalent stroke subtypes at 59,6%, followed with small vessel disease (SVD) at 26,7%, undetermined etiology at 9,8%, cardioembolism (CE) at 2,1%, and other determined etiology at 0,9%. Hypertension was the most common vascular risk factor. However, it was only significant in SVD (p=0,023) and undetermined etiology subtypes (p<0,001). Significant risk factor in LAA was diabetes (55%; p=0,016) while in CE subtypes was atrial fibrillation (60%;p<0,001). In multivariate analyses, hypertension (OR 3; 95% CI 1,12-8,05) was the only variable that was related to SVD while in CE it was atrial fibrillation (OR 113,5; 95% CI 13,6-946,5). Conclusion. LAA was the most common stroke ischemic subtypes. Associated risk factor in LAA was diabetes while in SVD and undetermined etiology subtypes it was hypertension. Atrial fibrillation was associated with cardioembolism.

Stroke is a leading cause of disability and mortality worldwide, and it disproportionately affects low- and middle-income countries (LMICs), which account for 88% of stroke fatalities. Prehospital stroke care delays are a crucial obstacle to successful treatment in these settings, especially given the limited therapeutic window for thrombolytic treatments, which may greatly improve recovery chances when initiated early after stroke onset. These delays are caused by a lack of public understanding of stroke symptoms, sociodemographic and cultural variables, and insufficient healthcare infrastructure. This review discusses these issues in detail, emphasizing the disparities in stroke awareness and reaction times between locations and socioeconomic classes. Innovative options for reducing these delays include the deployment of mobile stroke units and community-based educational campaigns. This review also discusses how technology improvements and personalized educational initiatives might improve stroke awareness and response in LMICs. The primary goal is to give a thorough assessment of the challenges and potential remedies that might serve as the foundation for policy reforms and healthcare improvements in LMICs, eventually improving stroke care and lowering disease-related mortality and disability.

Background and Purpose: Stroke is the number one cause of morbidity and mortality in Indonesia. Lacunar infarction is one of cerebral small vessel disease spectrum. This study aimed to present stroke epidemiology in Indonesia and risk factors associated with cerebral small vessel disease. Methods: A multicenter prospective cross-sectional study of 18 hospitals in Indonesia was conducted using Stroke Case Report Form from 2012 to 2014. Stroke was diagnosed based on clinical findings confirmed with non-contrast computed tomography of the brain. Subjects were classified into two large groups: ischemic (lacunar and non-lacunar) and hemorrhagic (intracranial and subarachnoid hemorrhage). Other risk factors were assessed on admission. Results: We enrolled 5411 patients, of whom 3627 (67.03%) had ischemic stroke and 1784 (32.97%) had hemorrhagic stroke. Male patients were prevalent in both large groups, although found less in subarachnoid hemorrhage group. Among patients with hemorrhagic stroke, 1603 (89.54%) of them had intracerebral hemorrhage and 181 (10.46%) had subarachnoid hemorrhage. From 3627 ischemic stroke patients, 1635 (45.07%) of them had lacunar infarction. We found that age above 55 years old, male gender, hypertension, dyslipidemia, and diabetes were important risk factors associated with lacunar stroke (p < 0.05). Conclusion: Ischemic stroke was the leading cause of stroke in Indonesia. In total, 45% of the total ischemic stroke patients had lacunar infarction. Important risk factors associated with lacunar infarction were hypertension, dyslipidemia, diabetes, age over 55, and male population.

Stroke is the leading cause of death and disability in the world as well as in Indonesia. Initial stroke severity is an important factor that affects short- and long-term stroke outcomes. This cross-sectional study was conducted in Cipto Mangunkusumo Hospital from July 2017 to January 2018 to investigate the factors that affect stroke severity. A total of 77 acute ischemic stroke patients were divided into three groups, which include low blood homocysteine levels (< 9 μmol/L), moderate blood homocysteine levels (9–15 μmol/L), and high blood homocysteine levels (> 15 μmol/L). The acquired data were analyzed using Kruskal–Wallis test and a significant difference of initial National Institute of Health Stroke Scale (NIHSS) and blood homocysteine levels (H = 13.328, p = 0.001) were seen, with a mean rank of 25.86 for low blood homocysteine levels, 33.69 for moderate blood homocysteine levels, and 48.94 for high blood homocysteine levels. The patients were then divided into two groups based on the NIHSS (≤5 and > 5) to calculate the risk correlation of blood homocysteine levels and NIHSS by using regression. We found that patients with high blood homocysteine levels had 14.4 times higher risk of having NIHSS > 5 compared with those with low blood homocysteine levels (p = 0.002, 95% confidence interval [CI] [2.714–76.407]), and 3.9 times higher risk compared with those with moderate blood homocysteine levels (p = 0.011, 95% CI [1.371–11.246]). We concluded that homocysteine is a risk factor for a higher stroke severity. Future studies to evaluate the usefulness of homocysteine-lowering therapy in stroke patients are recommended. This study has been approved by Ethics Committee of Faculty of Medicine, Indonesia University.

Objective. Clopidogrel is a common antiplatelet used as secondary prevention of ischemic stroke, known to have better efficacy than aspirin, with a equivalent safety profile. However, clopidogrel resistance is not uncommon but has not been widely studied in Asia. This study will further assess clopidogrel resistance and its risk factors.Materials and Methods. A cross-sectional study was conducted at Rumah Sakit Universitas, Indonesia, and Rumah Sakit Cipto Mangunkusumo, Indonesia in 2020-2021. All patients had had at least one episode of ischemic stroke. Clopidogrel resistance was assessed using a VerifyNow assay.Results. 57 subjects were enrolled in this study. We found 15.8% of subjects were clopidogrel resistant. Gender was significantly associated with clopidogrel resistance, with males having 80% lower clopidogrel resistance (OR 0.2 (95% CI 0.022 – 0.638); P=0.006). Meanwhile, smoking was not associated with clopidogrel responsiveness (P=0.051). We found no association between haemoglobin, blood glucose, HbA1c, cholesterol, liver enzymes, serum urea concentration or creatinine levels and clopidogrel resistance.Conclusion. Clopidogrel remains an effective treatment to prevent recurrent ischemic stroke in Indonesia. Further studies are needed to assess gene polymorphism and clopidogrel resistance, which may explain the findings of this study.

Background: COVID-19 increases the risk of acute ischemic stroke. The objective of this study is to identify the risk factors, comorbidities, and outcomes in COVID-19 patients with acute ischemic stroke at University of Indonesia Hospital. Results: The clinical condition of COVID-19 patients with ischemic stroke is more severe for patients older than 55 years (p < 0.05), patients at the critical COVID-19 clinical stage, and patients with atrial fibrillation (p < 0.05). The level of C-reactive protein (CRP) more than 60 mg/L correlated with the outcome of the patient as well. Conclusion: The study concluded that, age, COVID-19 clinical degree, and atrial fibrillation significantly affect the outcome in COVID-19 patients with stroke.
