Stroke is cardiovascular disease that causes the world's highest disability and is the most prevalence disease after heart disease and cancer. Stroke is caused by circulatory disorders with 80% of the sufferers are diagnosed with ischemic stroke and 20% of them are diagnosed with hemorrhagic stroke. Patients who survive from the first stroke have high risk to have recurrent stroke. American Heart Association/American Stroke Association and Perhimpunan Dokter Spesialis Syaraf Indonesia recommend secondary stroke prevention therapy including antiplatelet/anticoagulant, antihypertensive agents, and antidislipidemia to minimalize the risk of recurrent stroke. Secondary stroke prevention therapy is only the first step. Patients need to be adhere to those therapies. The non-adherence will increase the risk of recurrent stroke. The study aimed to determine factors which causing the non-adherence to secondary prevention therapy in patients with ischemic stroke. This was a case control study with concecutive sampling method by interviewing patients who met the inclusion criterias i.e., had been diagnosed and were inpatients due to ischemic stroke, but in the time of interview patients were outpatients, patients were able to communicate and agree to participate in the study.Data was analized by bivariate / chi square test and multivariate logistic regression test. During the study period, 184 respondents met the inclusion criterias. Factors affecting non-adherence in the use of secondary prevention therapy were No one reminded to take medicine p = 0.03; OR 4.51, denial of the disease p = 0,036 OR 214, and tired of taking medicine p = 0,045 OR 1,97.

Background and Purpose Despite administration of evidence-based therapies, residual risk of stroke recurrence persists. This study aimed to evaluate the residual risk of recurrent stroke in acute ischemic stroke or transient ischemic attack (TIA) with adherence to guideline-based secondary stroke prevention and identify the risk factors of the residual risk.Methods Patients with acute ischemic stroke or TIA within 7 hours were enrolled from 169 hospitals in Third China National Stroke Registry (CNSR-III) in China. Adherence to guideline-based secondary stroke prevention was defined as persistently receiving all of the five secondary prevention medications (antithrombotic, antidiabetic and antihypertensive agents, statin and anticoagulants) during hospitalization, at discharge, at 3, 6, and 12 months if eligible. The primary outcome was a new stroke at 12 months.Results Among 9,022 included patients (median age 63.0 years and 31.7% female), 3,146 (34.9%) were identified as adherence to guideline-based secondary prevention. Of all, 864 (9.6%) patients had recurrent stroke at 12 months, and the residual risk in patients with adherence to guidelinebased secondary prevention was 8.3%. Compared with those without adherence, patients with adherence to guideline-based secondary prevention had lower rate of recurrent stroke (hazard ratio, 0.85; 95% confidence interval, 0.74 to 0.99; P=0.04) at 12 months. Female, history of stroke, interleukin-6 ≥5.63 ng/L, and relevant intracranial artery stenosis were independent risk factors of the residual risk.Conclusions There was still a substantial residual risk of 12-month recurrent stroke even in patients with persistent adherence to guideline-based secondary stroke prevention. Future research should focus on efforts to reduce the residual risk.

Introduction: Aspirin is one of the most commonly used medications for cardiovascular disease and stroke prevention. Many older patients who present with a first or recurrent stroke are already on aspirin monotherapy, yet little evidence is available to guide antithrombotic strategies for these patients. Method: Using data from the American Heart Association Get With The Guidelines-Stroke Registry, we described discharge antithrombotic treatment pattern among Medicare beneficiaries without atrial fibrillation who were discharged alive for acute ischemic stroke from 1734 hospitals in the United States between October 2012 and December 2017. Results: Of 261,634 ischemic stroke survivors, 100,016 (38.2%) were on prior aspirin monotherapy (median age 78 years; 53% women; 79.4% initial stroke and 20.6% recurrent stroke). The most common discharge antithrombotics (Figure) were 81 mg aspirin monotherapy (20.9%), 325 mg aspirin monotherapy (18.2%), clopidogrel monotherapy (17.8%), and dual antiplatelet therapy (DAPT) of 81 mg aspirin and clopidogrel (17.1%). Combined, aspirin monotherapy, clopidogrel monotherapy, and DAPT accounted for 86.8% of discharge antithrombotics. The rest of 13.2% were discharged on either aspirin/dipyridamole, warfarin or non-vitamin K antagonist oral anticoagulants with or without antiplatelet, or no antithrombotics at all. Among patients with documented stroke etiology (TOAST criteria), 81 mg aspirin monotherapy (21.2-24.0%) was the most commonly prescribed antithrombotic for secondary stroke prevention. The only exception was those with large-artery atherosclerosis, in which, 25.3% received DAPT of 81 mg aspirin and clopidogrel at discharge. Conclusion: Substantial variations exist in discharge antithrombotic therapy for secondary stroke prevention in ischemic stroke with prior aspirin failure. Future research is needed to identify best management strategies to care for this complex but common clinical scenario.

Recurrent stroke remains the key health issue in the world. A higher three-year recurrence rate of stroke in patients with persistence of the genome of herpes viruses, and with presence in the blood of the genome of at least 2 types of viruses was identified. These investigations demonstrate the importance of further research into the role of antiviral therapy in improving the rehabilitation and secondary prevention of stroke in patients with persistent viral infection The purpose of the study was to evaluate the effectiveness of antiviral therapy in the secondary ischemic stroke prevention on the viral infection manifestation background. Material and methods. The study included 105 patients with moderate to severe ischemic stroke with a viral manifestation confirmed by the detection of herpes virus’s DNA (HSV1, HSV2, EBV, CMV, HHV6) and Flu RNA. Patients who were additionally prescribed antiviral drugs on the background of traditional therapy were in the main group (n = 35). Patients who received only traditional, recommended by the modern stroke treatment guidelines, therapy and secondary stroke prevention measures were included in the comparison group (n = 70). Results and discussion. We found that the effectiveness of the proposed preventive treatment depended on the viral load of the patient. In the presence of three or more types of viruses, the proposed therapy provided a significantly lower ischemic stroke recurrence rate, compared to the patients who did not receive antiviral therapy 11.1% vs. 49.8%, p = 0.042. Prevention of recurrent ischemic stroke, which should have started as soon as possible after the development of the first stroke or transient ischemic attack occurrence, F. Rincon and R. L. Sacco (2008) consider the most relevant in this group of patients. Herewith, as emphasized by D. G. Hackam and J. D. Spence (2007), comprehensive prevention has reduced the risk of recurrent ischemic stroke by almost 80%, thus preventing 4 out of 5 possible disorders. However, both native and world literature still has a lack of systematic data of the problem of antiviral therapy using in patients with acute disorders of cerebral circulation, although it has been proven that infectious and inflammatory complications are an important pathogenetic factor of its unfavorable and severe outcome. M. S. Elkind et al. (2016) consider that antiviral drugs such as acyclovir may play an appropriate role in the prevention of recurrent ischemic stroke in children if their causal relation is confirmed. Conclusion. The use of acyclovir in complex rehabilitation therapy and secondary stroke prevention in patients with viral infection manifestation provided an increase in the average score of Bartel index after 1 year, p = 0.017. In the case of antiviral therapy using in the complex prevention of recurrent vascular events in patients with viral infection manifestation, the three-year recurrence rate of stroke is lower (p = 0.042)

Background: Patients who had stroke recurrence after the first stroke have a high risk of disability as well as high rates of morbidity and mortality. Incidence of stroke recurrence can be prevented by controlling risk factors and secondary prevention among post stroke patient, and also tent of the duration of the occurrence of recurrent stroke after the first attack. Objective: The purpose of this study was to determine the characteristics and stroke recurrence periods of post stroke patients.Methods: Cross sectional study design was used in this study. Total 73 recurrent stroke patients age 18-60 years old were selected using consecutive sampling technique. This study was conducted on patients during their follow up in the outpatient department of unit neurology, Margono Soekardjo Purwokerto Hospital during November-December 2015. The characteristics of the recurrent stroke patients include sex, age, education, occupation, and income. This study also describes type of stroke and duration of illness. The periods of recurrent stroke patients divided in to three time periods (≤ 6-month, 7-12 month, >12 month). Results: 73 recurrent stroke patients showed 56% were female, age group 39-60 years old was 97,5%, 60,3% have low education (below senior high school), 64,7% work as public and private employees. Income of respondents were low income 53,4%. Ischemic stroke was the majority (87,7%), no history family of stroke 64,4%, 1-5 years duration of illness and periods of stroke recurrence >12 month was 45,20%.Conclusion:  Ischemic stroke is the biggest case of recurrent stroke, so that we need to emphasize the importance of secondary prevention including medication and treatment.

INTRODUCTION: The predominant underlying mechanism of lacunar stroke differs from that of other ischemic stroke subtypes. Accordingly, so may the ideal stroke prevention regimen. We aimed to evaluate the efficacy of different antiplatelet agents in lacunar stroke patients. Method: We searched MEDLINE, EMBASE and the Cochrane library for RCTs that evaluated antiplatelet therapy in patients with ischemic stroke. Trials which provided stroke recurrence rates in patients presenting with lacunar stroke, or where the data was obtainable from manuscript authors were included. In addition, we included the novel SPS3 trial’s antiplatelet arm data presented at the 2011 ISC. We performed pooled analysis to assess the crude frequency of recurrent stroke and a random effects meta-analysis. Results: Lacunar stroke data was available for 12 trials encompassing 35, 218 participants (mean age 65, 65% male). The pooled crude recurrent stroke rate was least for cilostazol monotherapy (6.2%), followed by ASA monotherapy (7.4%), clopidogrel monotherapy (8.6%), ASA/dipyridamole (8.6%) and greatest for ASA/clopidogrel therapy (9.1%). Rate ratios of lacunar stroke patients suggest no significant efficacy advantage for ASA [ASA vs placebo (RR 0.72, 95% CI 0.34-1.50; p=0.38)], ASA/clopidogrel [ASA/clopidogrel vs ASA (RR 0.80, 95% CI 0.62-1.03; p=0.08), ASA/clopidogrel vs clopidogrel (RR 0.95, 95% CI 0.79-1.15; p=0.63)], sarpogrelate [sarpogrelate vs ASA (RR 1.31, 95% CI 0.84-2.04; p=0.23)] and ASA/dipyridamole [ASA/dipyridamole vs ASA (RR 0.90, 95% CI 0.70-1.16; p=0.042)] for recurrent stroke. The results from Japanese trials evaluating the efficacy of cilostazol found that it is significantly better than both placebo (RR 0.51, 95% CI 0.30-0.85; p=0.01) and ASA (RR 0.70, 95% CI 0.51-0.96; p=0.03) in the secondary prevention of stroke. Conclusions: There seems to be no significant advantage among the various antiplatelet agents studied in lacunar stroke patients apart for cilostazol. However, this requires confirmation within large randomized trials outside of Japanese populations.

Introduction: The RESPECT-ESUS trial is proposed to evaluate the best stroke prevention strategy for patients with strokes of uncertain etiology. This trial will compare a novel anticoagulant with antiplatelet agents to prevent recurrent stroke among cryptogenic stroke patients. We sought to evaluate the eligibility for this trial within a large, biracial population representative of the US. Methods: All adult ischemic stroke patients in 2010 among residents of the 5-county Greater Cincinnati/Northern Kentucky region (population 1.3 million) were ascertained from all local hospitals via ICD-9 codes 430-436. Inclusion and exclusion criteria supplied by the corporate sponsor as of 6/30/14 were applied to the ischemic stroke population. Per trial protocol, a complete workup was defined as brain and both intra- and extracranial vascular imaging, ECHO, telemetry, and EKG. Results: Of 1894 ischemic stroke patients without hemorrhagic transformation who survived the hospital stay (and not sent to hospice), 138 (7.4%) would have been eligible for RESPECT-ESUS. Inclusion and exclusion criteria are listed in the Table. If we were to assume that every stroke patient received a complete workup and no further etiologies were identified, the “hypothetical” eligibility could be as high as 18.7%. Discussion: We found that the potential eligibility for the RESPECT-ESUS trial to be low, and in fact is similar to population-based estimates of rt-PA eligibility (6%-8%). Extrapolation of eligibility across the US would be further limited by presentation to an enrolling center and consent refusal rates. Our estimates are based on information obtained during hospitalization, which may over- or underestimate eligibility within the 3-6 month post-event enrollment window. It is likely that centers that participate in the trial will have more complete diagnostic workups, which was a major exclusion in our population, especially the requirement for intracranial vascular imaging.

Background: High blood pressure (BP) is a well recognized risk factor for ischemic stroke, and aggressive BP control is critical for secondary stroke prevention. However, hypertensive (HTN) outpatients are often found to have uncontrolled BP, in part due to poor compliance with daily at-home BP monitoring and consequent poor medication adherence. Here, we explore the association of patient home BP self-monitoring compliance with stroke recurrence. Method: Ischemic stroke patients with pre-existing HTN were prospectively recruited in accordance with IRB protocol for this observational study. All patients were trained on BP self-monitoring as per standard of care, and were asked to monitor BP at home daily consistently for 2 weeks. BP monitoring compliance, per completion of BP log, was assessed at each follow-up clinical visit by an investigator blinded to patient outcome. Stroke recurrence was followed for 5 years and independently adjudicated by two vascular neurologists. Result: In a total of 219 patients, only 36 patients (16.4%) were compliant in completing the home BP log as instructed. The compliant and non-compliant groups showed no baseline difference and no medication usage difference (p>0.05) (Table 1). Compliance with at-home BP monitoring was associated with well controlled systolic (p<0.001) and diastolic BP (p<0.001). Of note, 30 patients (16.4%) had recurrent strokes in the non-compliant group, while there were no recurrent strokes in the compliant group. BP self-monitoring compliance is associated with reduced incidence of stroke recurrence (p=0.030) and the significance remains robust after adjusting for multiple confounders (p=0.029) (Table 2). Conclusion: Regular home BP monitoring is associated with lower risk of stroke recurrence in HTN stroke patients. Study in expanded patient cohort is ongoing to leverage technology for better home BP monitoring and to create incentives for compliant behavior for better secondary stroke prevention.

Background: In the first 5 years after their stroke, about a quarter of patients will suffer from a recurrent stroke. Digital health interventions facilitating interactions between a caregiver and a patient from a distance are a promising approach to improve patient adherence to lifestyle changes proposed by secondary prevention guidelines. Many of these interventions are not implemented in daily practice, even though efficacy has been shown. One of the reasons can be the lack of clear economic incentives for implementation. We propose to map all health economic evidence regarding digital health interventions for secondary stroke prevention. Summary: We performed a systematic search according to PRISMA-P guidelines and searched on PubMed, Web of Science, Cochrane, and National Institute for Health Research Economic Evaluation Database. Only digital health interventions for secondary prevention in stroke patients were included and all study designs and health economic outcomes were accepted. We combined the terms “Stroke OR Cardiovascular,” “Secondary prevention,” “Digital health interventions,” and “Cost” in one search string using the AND operator. The search performed on April 20, 2017 yielded 163 records of which 26 duplicates were removed. After abstract screening, 20 articles were retained for full-text analysis, of which none reported any health economic evidence that could be included for analysis or discussion. Key Messages: There is a lack of evidence on health economic outcomes on digital health interventions for secondary stroke prevention. Future research in this area should take health economics into consideration when designing a trial and there is a clear need for health economic evidence and models.

Objective: Patients who survive from the first stroke have risk factors to be recurrent. Based on American Heart Association/American Stroke Association and PERDOSSI (Indonesian Neurologist Association), medications which are prescribed to reduce the risk of recurrent stroke as secondary stroke prevention therapies include antiplatelet/anticoagulant as well as antihypertensive and lipid lowering agent. Patients’ adherence to the secondary stroke prevention therapies is important to reduce the recurrent stroke. Methods: This is a quantitative research and the data was collected retrospectively. The number of subjects of this study were 165 respondents. The participants were interviewed by researchers about their adherence to secondary stroke prevention by Modified Morisky Adherence Scale 8 (MMAS-8) questionnaire. Patients’ adherence was stated as low (MMAS-8 score < 6); moderate (MMAS-8 score = 6-7) and high (MMAS-8 = 8). This research was taken at a teaching hospital in Central Java Indonesia.Results: Of 165 participants, 48 participants (29%) were categorized to have low adherence, 43 participants (26%) had moderate adherence, and 74 participants (45%) had high adherence to secondary stroke prevention therapies. The reasons for not adhering to the medications were felt better (34.1%), forgetfulness (18.7%), boredom (16.5%), lack of family support (8.8%), lack of time (6.6%), felt worse (5.5%), concern about side effects (3.3%), preference to Complementary Alternative Medicines (3.3%), and cost (3.3%).Conclusion: The number of patients who has high adherence to secondary stroke prevention was 45% and the most common reason why participants did not adhere to therapy was because they felt better (34.1%).

Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors) clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.
