Secular trends in the cardiovascular risk profile and mortality of stroke admissions in an inner city, multiethnic population in the United Kingdom (1997-2005)

Our objective was to study ethnic differences in the cardiovascular risk profile and mortality of stroke admissions to an inner city teaching hospital serving a multiethnic population in Birmingham, UK, over a 9-year period (1997-2005). Hospital case notes and registry data of 3083 patients admitted with a first onset stroke were reviewed. Secular trends in the prevalence of risk factors (hypertension, diabetes, hyperlipidaemia, atrial fibrillation and myocardial infarction), hospital admission rates and 30-day mortality among Afro-Caribbean, European Caucasian and South Asian ethnic groups were analysed. Between 1997 and 2005, there were 3083 first onset strokes, of whom 47.6% (1595) were men, 9.3% Afro-Caribbean, 57.8% European Caucasian and 15.1% South Asian. There was a significant trend towards a reduction in non-haemorrhagic stroke admissions over the study period (P
