Background: There is a paucity of data on patients with stroke/transient ischaemic attack in low- and middle-income countries. We sought to describe the characteristics and management of patients with an ischaemic stroke and recent transient ischaemic attack or minor ischaemic strokes in low- or middle-income countries. Methods: The Outcomes in Patients with TIA and Cerebrovascular disease registry is an international, prospective study. Patients ≥45 years who required secondary prevention of stroke (either following an acute transient ischaemic attack or minor ischaemic strokes (National Institutes of Health Stroke Scale <4) of <24h duration, or recent (<6 months), stable, first-ever, non-disabling ischaemic stroke) were enrolled in 17 countries in Latin America, the Middle East, and Africa. The main measures of interest were risk factors, comorbidities, and socio-economic variables. Results: Between January 2007 and December 2008, 3635 patients were enrolled in Latin America (n=1543), the Middle East (n=1041), North Africa (n=834), and South Africa (n=217). Of these, 63% had a stable, first-ever ischaemic stroke (median delay from symptom onset to inclusion, 25 days interquartile range, 7-77); 37% had an acute transient ischaemic attack or minor ischaemic stroke (median delay, two-days; interquartile range, 0-6). Prevalence of diabetes was 46% in the Middle East, 29% in Latin America, 35% in South Africa, and 38% in North Africa; 72% had abdominal obesity (range, 65-78%; adjusted P<0·001); prevalence of metabolic syndrome was 78% (range, 72-84%, P<0·001). Abnormal ankle brachial index (<0·9) was present in 22%, peripheral artery disease in 7·6%, and coronary artery disease in 13%. Overall, 24% of patients had no health insurance and 27% had a low educational level. Interpretation: In this study, patients in low- and middle-income countries had a high burden of modifiable risk factors. High rates of low educational level and lack of health insurance in certain regions are potential obstacles to risk factor control.
