| dc.description.abstract | Background: Stroke is one of the most common causes of morbidity and mortality the world over. Established risk factors such as arterial hypertension, diabetes mellitus, cigarette smoking, hyper-lipidaemia, micro-vascular rupture, male gender, age and observed co-morbities such as sickle cell disease, HIV/AIDS infection and cerebral malaria are increasingly being encountered in the tropics.
Objectives: To determine pathological sub-types, risk factors, in-hospital period prevalence and in-hospital outcome of stroke.
Design: Hospital-based retrospective study.
Setting: The Nairobi Hospital, Nairobi, Kenya.
Subjects: Patients with recorded diagnosis of stroke/cerebral vascular accident; as per WHO criteria for diagnosis of stroke, all gender and age≥ 18 years were studied.
Results: A total of 2629 patients were admitted to the division of medicine at the hospital during study period. Eighty patients had diagnosis of stroke; giving an in-hospital period prevalence of 3042/100,000. Mean age was 61.3 years, mode; 63 years, range 34-95 years. Males were 43 (53.8%), M to F ratio 1.2: 1 stroke sub-types: Ischaemic stroke 68 (85%), haemorrhagic stroke seven (8.8%). In five patients (6.3%) no evidence of stroke sub-type was on-record. Established risk factors for stroke included hypertension and diabetes mellitus. Hypertension was found in 64 patients (80%) and diabetes-mellitus in 27 (33.7%). Twenty three patients (28.8%) had both hypertension and diabetes-mellitus. Co-morbidities were observed and included mitral-stenosis, cardiac-arrhythmias cardio-myopathy, HIV/AIDS, Left Ventricular Hypertrophy (LVH), infective endocarditis, atrial septal | en_US |
