Abstract
Recent studies have suggested that microalbuminuria is relatively common (9.4%) in non-diabetic subjects and that it is an excellent marker for increased cardiovascular risk. In an attempt to assess the prevalence of microalbuminuria in Northern Ireland where there is a high incidence of coronary heart disease, we studied 400 males, age 35-65 years, chosen at random from a Belfast general practice. There was a 73% response rate (n=273). Sixteen per cent of the population has ischaemic heart disease.
Microalbuminuria was defined as an increased urinary albumin excretion rate of 20-200 ug min-1. Thirteen subjects (4.7 %) had an albumin excretion rate of 20 ug min-1 or more. After exclusion of subjects with diabetes mellitus or renal diseases, the group with microalbuminuria (n=8), was compared to those without microalbuminuria (n=256) There was no significant difference in the incidence of ischaemic heart disease between the two groups, nor did the group with microalbuminuria have a more adverse profile of vascular risk factors, apart from serum triglyceride (1.8 ± 0.2 v 1.3 ± 0.0 mmol 1-1, p<0.05) and plasma glucose (53 ± 0.3 v 5.1 ± 0.3 mmol 1-1, p<0.05) levels.
We conclude that in a general practice from an area at high risk of ischaemic heart disease, the prevalence of microalbuminuria was low. Contrary to previous reports, microalbuminuria was not helpful in predicting subjects at risk of ischaemic heart disease.
