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.

Secondary Stroke Prevention

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: Atrial fibrillation (AF) and large artery diseases (LAD) share several risk factors and often coexist in the same patient. Optimal treatments for acute ischemic stroke (AIS) patients with concomitant AF and LAD have not been extensively studied so far. Objective: This study aimed to compare the effectiveness of the addition of antiplatelet (AP) to oral anticoagulant (OAC) with that of OAC alone in AIS with AF according to the LAD. Methods: Using a multicenter stroke registry, acute (within 48h of onset) and mild-to-moderate (NIHSS score ≤15) stroke patients with AF were identified. Propensity scores using IPTW were used to adjust baseline imbalances between the OAC+AP group and the OAC alone group in all patients and in each subgroup by LAD. The primary outcome was major vascular events, defined as the composite of recurrent stroke, MI, and all-cause mortality at up to 3 months after index stroke. Results: Among the 5469 patients (age, 72±10yrs; male, 54.9%; initial NIHSS score, 4 [2-9]), 79.0% (n=4323) received OAC alone, and 21.0% (n=1146) received OAC+AP. By weighted Cox proportional hazards analysis, a tendency of increasing the risk of 3-months primary composite events in the OAC+AP group vs the OAC alone (HR 1.36 [0.99-1.87], p=0.06), with significant interaction with treatments and LAD (Pint=0.048). Briefly, among patients with moderate-to-severe large artery stenosis, tendency of decrease in 3-months primary composite events of the OAC+AP group, compared with OAC alone group, was observed (HR 0.54 [0.17-1.70]), whereas among patients with complete occlusion, the OAC+AP group markedly increased the risk of 3-months composite events (HR 2.00 [1.27-3.15]), compared with the OAC alone group. No interaction between direct oral anticoagulant and warfarin on outcome was observed (Pint=0.35). Conclusion: In conclusion, treatment with addition of AP to OAC had a tendency to increase the risk of 3-months vascular events, compared with OAC alone in AIS with AF. However, the effects of antithrombotic treatment could be modified according to the LAD, with substantial benefits of OAC alone in subgroup of large artery occlusion. Our results address the need for the further study to tailor the optimal treatment in AIS with concomitant AF and LAD.

Atrial fibrillation is one of the most common arrhythmias, with a significant increase in incidence in recent years. AF is a major cause of stroke, heart failure, sudden cardiac death, and cardiovascular disease. Timely intervention and modification of risk factors increase chance to stop the disease. Aggressive, multilevel prevention tactics are a component of combined treatment, including – in addition to lifestyle changes, anticoagulant therapy, pharmacotherapy and invasive anti-arrhythmic treatment – prevention of cardiovascular diseases, hypertension, ischemia, valvular disease and heart failure.

Background: We investigated the effect of D-dimer levels and efficacy of different antithrombotic therapies according to the baseline D-dimer levels on recurrent stroke in patients with atrial fibrillation (AF)-related stroke and atherosclerosis. Methods: We enrolled 1441 patients with AF-related stroke and atherosclerosis in this nationwide multicenter study. The primary outcome measure was the occurrence of recurrent ischemic stroke over a 3-year period. Results: High D-dimer levels (≥2 μg/mL) were significantly associated with higher risk of recurrent ischemic stroke (adjusted hazard ratio (HR), 1.80; 95% confidence interval (CI), 1.13–2.84; p = 0.012). The risk of recurrent stroke was similar between the anticoagulant and the antiplatelet groups in all subjects (adjusted HR, 0.78; 95% CI, 0.46–1.32; p = 0.369). However, in patients with high D-dimer levels (≥2 μg/mL), risk of recurrent stroke was significantly lower in the anticoagulant group than in the antiplatelet group (adjusted HR, 0.40; 95% CI, 0.18–0.87; p = 0.022). Conclusion: Our findings suggested that baseline D-dimer levels could be used as a risk assessment biomarker of recurrent stroke in patients with AF-related stroke and atherosclerosis. High D-dimer levels would facilitate the identification of patients who are more likely to benefit from anticoagulants to ensure secondary prevention of stroke.

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)

Abstract Background: Identifying risk factors of cardiovascular events is crucial for stroke prevention and they can be used as predictive factors of stroke outcomes.In this study, it is to evaluate the risk factors that predict outcomes of acute non-cardioembolic ischemic stroke in patients stratified by Essen Stroke Risk Score (ESRS). Methods: A retrospective study was carried out in acute non-cardioembolic ischemic stroke patients in a Chinese tertiary-care teaching hospital. ESRS stratification and factors that might influence the outcomes of stroke, as indicated by fatal or non-fatal combined vascular events of recurrent stroke, myocardial infarction, or primary intracranial hemorrhage, were documented. Univariate analysis and multivariable regression analysis was used to identify independent predictors of stroke outcomes. Results: A total of 878 patients with acute non-cardioembolic ischemic stroke who completed a mean follow-up of 5.2 years were enrolled, and 163 patients experienced at least one component of the combined vascular event. In patients with an ESRS ≤ 3, age ≥ 65 years (OR , 2.935; 95% CI 1.625-5.301, P < 0.001) and clopidogrel treatment (OR , 1.685 ; 95% CI , 1.026-2.768; P = 0.041) were significantly associated with stroke outcomes. In patients with an ESRS > 3, age ≥ 65 years (OR , 2.107, 95% CI , 1.208-3.673 ; P = 0.008) and history of diabetes (OR , 1.465 ; 95% CI , 1.041–2.062 ; P = 0.027) were risk factors for stroke outcomes , whereas clopidogrel treatment (OR , 0.542; 95% CI , 0.356–0.824; P = 0.003) was a protective factor for stroke outcomes. Conclusions: According to this study, clopidogrel treatment, blood pressure control, and glycemic control are protective factors for stroke outcomes in high-risk patients (ESRS>3).

Background In older adults with stroke, there is an increased risk of cardiovascular events in the intermediate period, up to one year after stroke. The risk of cardiovascular events in this period in young adults after stroke has not been studied. We hypothesized that in the intermediate risk period, young adults with ischemic stroke have an increased risk of recurrent stroke and a smaller increase of cardiac events. Methods Using the National Readmissions Database during the year 2013, we identified ischemic stroke admissions among those aged 18–45 years using International Classification of Disease, Ninth Revision, Clinical Modification codes to identify index vascular events and risk factors. Primary outcomes were readmission for cardiac events and stroke. Multivariable Cox proportional hazard models and Kaplan–Meier analysis were used to estimate risk of primary outcomes. Results We identified 12,392 young adults with index stroke. The readmission rate due to recurrent stroke was higher than for cardiac events (2913.3.1 vs. 1132.4 per 100,000 index hospitalizations at 90 days). There was a higher cumulative risk of both cardiac events and recurrent stroke in the presence of baseline diabetes and hypercholesterolemia. Conclusion In a large, nationally representative database, the intermediate risk of recurrent stroke after index stroke in young adults was higher than the risk of cardiac events. The presence of vascular risk factors augmented this risk but did not entirely account for it. The aggressive control of hypercholesterolemia and diabetes may play an important role in secondary prevention in young adults with stroke.

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.
