AIMS: Mortality rates for coronary heart disease (CHD) have declined substantially in developed countries. Diabetes mellitus is an important risk factor for CHD; its prevalence is increasing. We aimed to compare trends in population-based mortality for CHD without diabetes on the death certificate with trends for CHD with diabetes on the same certificate. METHODS: Analysis of an all-England dataset with multiple-cause coded mortality records from 1995 to 2010. Analysis of a similar dataset for Oxford, because it has the longest run of multiple-cause coded mortality in England, from 1979. Age-specific and age-standardized mortality rates were calculated. RESULTS: In the all-England dataset, there were 1 772 760 deaths with CHD and no mention of diabetes; and 173 184 deaths with CHD and diabetes on the same death certificate. Of deaths with CHD without a mention of diabetes, rates per million men fell by more than half from 2843 (95% confidence interval: 2822-2862) in 1995 to 1379 (1366-1391) in 2010; and those in women halved from 1324 (1314-1336) to 628 (621-635). Of deaths with CHD and diabetes, rates per million men increased from 194 (188-200) to 215 (210-220); and those for women fell, but only very slightly, from 114 (111-118) to 101 (98-104). The longer run in Oxford, from 1979, showed that rates in men and women without diabetes had fallen by two-thirds; but that rates for CHD with diabetes had not fallen. CONCLUSIONS: The fall in mortality from CHD without diabetes has been spectacular. There has been no comparable fall in mortality from CHD with diabetes.
