These comprehensive and novel clinical imaging data will prove useful in refining stroke guidelines and advancing stroke care in India.

Rationale Recurrent stroke, cardiovascular morbidity, and mortality are important causes of poor outcome in patients with index stroke. Despite the availability of best medical management recurrent stroke occur in up to 15–20% of patients with stroke in India. Education for stroke prevention could be a strategy to prevent recurrent strokes. Hypothesis We hypothesize that a structured semi-interactive stroke prevention package can reduce the risk of recurrent strokes, acute coronary artery syndrome, and death in patients with sub-acute stroke at the end of one year. Design Secondary Prevention by Structured Semi-Interactive Stroke Prevention Package in INDIA (SPRINT INDIA) is a multi-center stroke trial involving 25 centers under the Indian Stroke Clinical Trial Network. Patients with first ever sub-acute stroke within two days to three months of onset, age 18–85 years, mRS <5, showing recent stroke in imaging are included. Participants or caregivers able to read and complete tasks suggested in a stroke prevention workbook and have a cellular device for receiving short message service and watching videos. A total of 5830 stroke patients speaking 11 different languages are being randomized to intervention or control arm. Patients in the intervention arm are receiving a stroke prevention workbook, regular educational short messages, and videos. All patients in the control arm are receiving standard of care management. Summary Structured semi-interactive stroke prevention package may reduce the risk of recurrent strokes, acute coronary artery syndrome, and death in patients with sub-acute stroke. Trial registration This trial is registered with clinicaltrials.gov (NCT03228979) and CTRI (Clinical Trial Registry India; CTRI/2017/09/009600).

These data provide insights into the status of ischemic stroke care in academic urban centers within 2 large Asian countries. Further research is needed to determine whether these patterns are representative of care across the countries, to explain differences in observed severity, and to drive improvements.
