Ischemic stroke causes death and disability worldwide. Better understanding and controlling factors associated will improve the prevention of the disease. This study reviews records of patients with ischemic stroke in Central Africa.
Patients of Bantu ethnicity with clinical diagnosis of stroke and lesion on computed tomography scan from January 2011 to December 2012 were selected. Computed tomographic subtypes of ischemic stroke and factors associated were considered with tropical seasonal variation.
Of the 303 first-ever stroke patients (average age 53 years old, range 3- 84 years old; 62% male) were included in the study. The prevalence of computed tomography stroke subtypes was: lacunar infarct (63%) and non lacunar infarct lesion (37%). Silent brain infarct was seen in 9 % of patients. Prevalence of factors associated with ischemic stroke was: age≥60 years old (55%); male gender (63%), chronic and uncontrolled hypertension (54%) and type 2 Diabetes mellitus (11%). A seasonal high prevalence was observed in warmer season (p < 0.05).
This study shows a high prevalence of lacunar infarct than non lacunar in Bantu of Central Africa.
缺血性中风在全球范围内导致死亡和残疾。更好地理解和控制相关因素将改善该疾病的预防。本研究回顾了中非地区缺血性中风患者的记录。
选取2011年1月至2012年12月期间临床诊断为中风且计算机断层扫描有病变的班图族患者。考虑缺血性中风的计算机断层扫描亚型及相关因素与热带季节变化的关系。
303例首次中风患者（平均年龄53岁，范围3 - 84岁；62%为男性）纳入研究。计算机断层扫描中风亚型的患病率为：腔隙性梗死（63%）和非腔隙性梗死病变（37%）。9%的患者有无症状脑梗死。与缺血性中风相关因素的患病率为：年龄≥60岁（55%）；男性（63%），慢性且未控制的高血压（54%）和2型糖尿病（11%）。在温暖季节观察到季节性高患病率（p < 0.05）。
本研究表明，在中非班图族中，腔隙性梗死的患病率高于非腔隙性梗死。
