Abstract:
Objective: To investigate the relationship between Oxfordshire community stroke project (OCSP) classification (and each subtype) and the risk factors for stroke. Methods: Nine hundred thirty-two consecutive patients with ischemic stroke from the symptom onset to admission < 2 weeks were registered. The patients were divided into 4 groups according to the OCSP classification criteria: total anterior circulation infarction (TACI), partial anterior circulation infarction (PACI), lacunar infarction (LACI), and posterior circulation infarction (POCI). The gender, age, nationality of the patients as well as the history of hypertension, diabetes, hyperlipidemia, smoking, and alcohol consumption were recorded. The effects of different risk factors on each subtypes of stroke were analyzed. Results: Circled digit oneAmong the 932 patients, there were 463 patients (49.7%) in the LACI group, 326 (35.0%) in the PACI group, 78(8.4%) in POCI group, and 65 (7.0%) in the TACI group. Circled digit twoThere were no significant differences in age, hypertension, diabetes, hyperlipidemia, cerebral hemorrhage, and history of smoking among all subtype groups. The proportion of male was the highest (75. 6%) in the OCSP group; the proportions of Muslim (21.5%), ischemic stroke (36. 9%), atrial fibrillation (20.0%), and TIA (21.5%) patients were the highest in the TACI group (21.5%); the proportion of alcoholic drinkers was the highest in the LACI group (50.3%). Circled digit threeThere were no significant differences on the relative risk of the occurrence of POCI in patients with history of diabetes, hypertension, hyperlipidemia, smoking, alcohol consumption, ischemic stroke, TIA, cerebral hemorrhage, and atrial fibrillation. There were no significant differences on the relative risks of the occurrence of all types of stroke in patients with history of diabetes, hypertension, hyperlipidemia, and smoking. The history of alcohol consumption and TIA increased the risk of LACI (OR, 1.488, 95% CI 1.148-1.928; OR, 1.686, 95% CI 1.155-2.462); the history of ischemic stroke increased the risks of PACI and TACI (OR, 1.466, 95% CI 1.058-2.032; OR, 2.472, 95% CI 1.453-4.205); the history of intracerebral hemorrhage increased the risk of TACI (OR, 2.570, 95% CI 1.036-6.379); atrial fibrillation increased the risk of TACI (OR, 4.266, 95% CI 2.174-8.368). Conclusion: The incidence of the LACI subtype was the highest among all the OCSP subtypes. The different risk factors may increase the risks of different subtypes of OCSP.
