Abstract
OBJECTIVE
To investigate the influence of age and social circumstances on probability of revascularisation among British men.
DESIGN
Prospective population based study
SETTING
24 medium sized British towns, none of which contained a hospital undertaking coronary artery bypass surgery.
SUBJECTS
5814 surviving participants of the BRHS (British regional heart study), aged 52-73 years, with no history of revascularisation when responding to a questionnaire in November 1992.
MAIN OUTCOMES
Incident coronary revascularisations, as documented in general practitioner records, over the following 7.1 years and coronary angiography investigations reported by men in a further questionnaire in November 1996.
RESULTS
160 men underwent at least one revascularisation during this period (4.2/1000 person-years). In multifactorial analysis, which included adjustment for incidence of major coronary heart disease or angina, a lower incidence of revascularisation was found among men aged over 65 years in November 1992 (hazard ratio 0.62, 95% confidence interval (CI) 0.44 to 0.87), among men with manual occupations (0.73, 95% CI 0.53 to 1.02), among men living in households possessing no car (0.44, 95% CI 0.24 to 0.80) or one car (0.60, 95% CI 0.42 to 0.87) compared with two or more cars, among council tenants (0.49, 95% CI 0.25 to 0.97), and among men living outside southern England (0.71, 95% CI 0.51 to 0.99). Only car ownership was related to the incidence of diagnostic angiography: the odds ratio for angiography for those owning fewer than two cars was 0.62 (95% CI 0.42 to 0.89).
CONCLUSION
During the 1990s, there were major inequalities in the probability of undergoing coronary revascularisation between British men according to socioeconomic status, age, and geographic location.
