Abstract

Objective: Cerebral vascular events are the second leading cause of mortality worldwide and is increasing
in developing countries. Epidemiological studies are important to improve outcomes and preventive and
supportive strategies. This research was aimed to study epidemiology of stroke in Tabriz, Iran.
Materials and Methods: This cross-sectional, analytic population-based study was performed from May
2009 to April 2010. Information about probable stroke events was obtained from 5000 randomly selected
people. In a door-to-door process, questionnaires were completed by a trained team. Any probable stroke
case was referred to a stroke expert for further evaluation. After diagnosing stroke cases, 214 healthy
people were assembled for a control group to compare stroke related risk factors.
Results: Out of 5000 studied people, 34(0.68%) stroke patients, with a mean age of 68.7 years (range:
38-85), were detected. Nineteen (56%) patients were male, 31 (91%) were ischemic, and 3 (9%) had
hemorrhagic stroke. Six first-ever strokes occurred in the 1 year study period. Identified risk factors
included hypertension in 25 (74%), hyperlipidemia in 11 (32%), diabetes mellitus in 9 (27%), smoking in
10 (29%) and coronary artery disease in 6 (18%).
Conclusion: This report showed a high incidence rate of stroke of about 120 per 100,000 people and a
remarkably high prevalence of hypertension. It speaks to the need to make special health system strategies
to raise awareness for primary and secondary prevention of stroke.
