<jats:p><jats:bold>Introduction:</jats:bold> Stroke is one of the leading causes of death in Latin America, a region with countless gaps to be addressed to decrease its burden. In 2018, at the first Latin American Stroke Ministerial Meeting, stroke physician and healthcare manager representatives from 13 countries signed the Declaration of Gramado with the priorities to improve the region, with the commitment to implement all evidence-based strategies for stroke care. The second meeting in March 2020 reviewed the achievements in 2 years and discussed new objectives. This paper will review the 2-year advances and future plans of the Latin American alliance for stroke.</jats:p><jats:p><jats:bold>Method:</jats:bold> In March 2020, a survey based on the Declaration of Gramado items was sent to the neurologists participants of the Stroke Ministerial Meetings. The results were confirmed with representatives of the Ministries of Health and leaders from the countries at the second Latin American Stroke Ministerial Meeting.</jats:p><jats:p><jats:bold>Results:</jats:bold> In 2 years, public stroke awareness initiatives increased from 25 to 75% of countries. All countries have started programs to encourage physical activity, and there has been an increase in the number of countries that implement, at least partially, strategies to identify and treat hypertension, diabetes, and lifestyle risk factors. Programs to identify and treat dyslipidemia and atrial fibrillation still remained poor. The number of stroke centers increased from 322 to 448, all of them providing intravenous thrombolysis, with an increase in countries with stroke units. All countries have mechanical thrombectomy, but mostly restricted to a few private hospitals. Pre-hospital organization remains limited. The utilization of telemedicine has increased but is restricted to a few hospitals and is not widely available throughout the country. Patients have late, if any, access to rehabilitation after hospital discharge.</jats:p><jats:p><jats:bold>Conclusion:</jats:bold> The initiative to collaborate, exchange experiences, and unite societies and governments to improve stroke care in Latin America has yielded good results. Important advances have been made in the region in terms of increasing the number of acute stroke care services, implementing reperfusion treatments and creating programs for the detection and treatment of risk factors. We hope that this approach can reduce inequalities in stroke care in Latin America and serves as a model for other under-resourced environments.</jats:p>

<jats:p>Objective. A narrative overview of regional academic research collaborations to address the increasing burden and gaps in care for patients at risk of, and who suffer from, stroke in Latin America (LA). Materials and methods. A summary of experiences and knowledge of the local situation is presented. No systematic literature review was performed. Results. The rapidly increasing burden of stroke poses immense challenges in LA, where prevention and management strategies are highly uneven and inadequate. Clinical research is increasing through various academic consortia and networks formed to overcome structural, funding and skill barriers. However, strengthening the ability to generate, analyze and interpret randomized evidence is central to further develop effective therapies and healthcare systems in LA. Conclusions. Regional networks foster the conduct of multicenter studies –particularly randomized controlled trials–, even in resource-poor regions. They also contribute to the external validity of international studies and strengthen systems of care, clinical skills, critical thinking, and international knowledge exchange.</jats:p>

<jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Low ankle-brachial index (ABI) identifies a stroke subgroup with high risk of recurrent stroke, cardiovascular events, and death. However, limited data exist on the relationship between low ABI and stroke in low and middle-income countries. Therefore, we evaluated the prevalence of ABI ≤0.90 (which is diagnostic of peripheral artery disease) in nonembolic stroke patients or transient ischemic attack and assessed the correlation of low ABI with stroke risk, factors, and recurrent vascular events and death.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>Patients ≥45 years with acute transient ischemic attack or minor ischemic strokes were recruited consecutively from over 17 low-income and middle-income countries (Latin America [1543 patients], Middle East [1041 patients], North Africa [834 patients], and South Africa [217 patients]). The ABI measurement was performed at a single visit. Stroke recurrence and risk of new vascular events were assessed after 24 months of follow-up.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p> Among 3487 enrolled patients, abnormal ABI (<0.9) was present in 22.3 %. Patients with an ABI of ≤0.9 were more likely ( <jats:italic>P</jats:italic> <0.05) to be male, older, and have a history of peripheral artery disease, hypertension, and diabetes mellitus. During 2-year follow-up, the rate of major cardiovascular event was higher in patients with ABI <0.9 than those with ABI ≥0.9 (Kaplan-Meier estimates, 22.5%; 95% CI, 19.6–25.8 versus 13.7%; 21.4–15.1; <jats:italic>P</jats:italic> <0.001), and when ABI was categorized into 4 groups (≤0.6; 95% CI, 0.6–0.9; 0.9–1; 1–1.4), the rate of major cardiovascular event was higher in those with ABI ≤0.6 than the other groups (Kaplan-Meier estimates, 32.6%; 95% CI, 21.0–48.3 for ABI≤0.6 versus 21.7%; 95% CI, 18.8–25.0 for ABI 0.6–0.9 versus 14.3%; 95% CI, 12.4–16.6 for ABI 0.9–1 versus 13.3%; 95% CI, 11.6–15.2 for ABI 1–1.4; <jats:italic>P</jats:italic> <0.001). </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>Among patients with nonembolic ischemic stroke or transient ischemic attack, those with low ABI had a higher rate of vascular events and death in this population. Screening for ABI in stroke patients may help identify patients at high risk of future events.</jats:p> </jats:sec>
