Risk factors and 30-day case fatality of first-ever stroke in Basrah, Iraq.

Abstract

Background:The aim of this hospital-based study is to determine the types, the frequency of risk factors and the 30-day case fatality of first-ever stroke in Basrah, Iraq.Materials and Methods:This was a hospital-based prospective study between January 2008 and July 2008 in Basrah, Iraq. Two hundred twenty-five (225) patients, who were admitted for first-ever stroke to the four major hospitals in Basrah, were interviewed and followed up for 30 days. Risk factors studied were smoking, history of diabetes mellitus, hypertension, atrial fibrillation, ischaemic heart diseases and transient ischaemic attack.Results:The mean age of the studied subjects was 63.8 ± 12.3 years. Males constituted 56% of cases. Clinical types of stroke were ischaemic stroke (83.6%), intracerebral haemorrhage (16%) and subarachnoid haemorrhage (0.4%). The prevalence of risk factors was; hypertension (66.2%), family history of stroke (31.6%), ischaemic heart diseases (28.9%), smoking (28.4%), diabetes mellitus (28%), transient ischaemic attack (10.2%), atrial fibrillation (9.8%) and heart failure (5.8%). The 30-day case fatality rate was 22.7%.Conclusions:Ischaemic stroke was the highly prevalent type. Hypertension, family history of stroke, ischaemic heart diseases, smoking and diabetes mellitus were the major risk factors of first ever stroke in Basrah. The 30-day case fatality rate of stroke in Basrah was nearly similar to that in western countries, but higher than that reported in the neighbouring Arab countries. Early detection of modifiable risk factors that can prevent stroke or at least minimise its complications is highly recommended.
