| Abstract | BACKGROUND AND PURPOSE: Acute cerebral ischemia is frequently associated with headache. It is unknown whether concomitant headache reflects a partly different pathogenesis, and thus, may influence long-term prognosis after stroke. Here, we compared the long-term risk of recurrent vascular events in patients in whom a transient ischemic attack or minor ischemic stroke of noncardioembolic origin was associated with headache with those without headache. METHODS: We used data from the Life Long After Cerebral ischemia (LiLAC) cohort. Participants were grouped on the basis of presence or absence of headache at presentation. We calculated the hazard ratios (HRs) and corresponding 95% confidence intervals (CI) for any first vascular event (primary outcome) or any cardiac or cerebral event (secondary outcomes). Adjustments were made for baseline clinical characteristics. RESULTS: Of 2473 participants, 420 (17%) experienced headache during the acute event. Median follow-up was 14.1 years. For the primary outcome, the crude HR of headache versus no headache was 0.75 (95% CI, 0.66-0.89) and the adjusted HR 0.83 (95% CI, 0.71-0.97). For cardiac events the adjusted HR was 0.88 (95% CI, 0.67-1.14) and for cerebral events, 0.97 (95% CI, 0.76-1.24). The ratio of cardiac versus cerebral events, however, did not differ between the 2 groups. Participants with headache were at lower risk of vascular death (adjusted HR, 0.73; 95% CI, 0.61-0.87). CONCLUSIONS: Patients who experienced headache in association with a transient ischemic attack or minor ischemic stroke have a better vascular prognosis than those without concomitant headache. This may, at least partly, reflect a different pathogenesis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
