Maturity-onset diabetes independently increased the risk of nonfatal myocardial infarction and fatal coronary heart disease in middle-aged women (RR 3.1; 95% CI 2.3-4.2).
Cohort (n=116,177)
Effect estimate: RR 3.1 (95% CI 2.3 to 4.2)
We examined the relationship of maturity-onset clinical diabetes mellitus with the subsequent incidence of coronary heart disease, stroke, total cardiovascular mortality, and all-cause mortality in a cohort of 116,177 US women who were 30 to 55 years of age and free of known coronary heart disease, stroke, and cancer in 1976. During 8 years of follow-up (889 255 person-years), we identified 338 nonfatal myocardial infarctions, 111 coronary deaths, 259 strokes, 238 cardiovascular deaths, and 1349 deaths from all causes. Diabetes was associated with a markedly increased risk of nonfatal myocardial infarction and fatal coronary heart disease (age-adjusted relative risk RR = 6.7; 95% confidence interval CI, 5.3 to 8.4), ischemic stroke (RR = 5.4; 95% CI, 3.3 to 9.0), total cardiovascular mortality (RR = 6.3; 95% CI, 4.6 to 8.6), and all-cause mortality (RR = 3.0; 95% CI, 2.5 to 3.7). A major independent effect of diabetes persisted in multivariate analyses after simultaneous control for other known coronary risk factors (for these end points, RR 95% CI = 3.1 2.3 to 4.2, 3.0 1.6 to 5.7, 3.0 1.9 to 4.8, and 1.9 1.4 to 2.4, respectively). The absolute excess coronary risk due to diabetes was greater in the presence of other risk factors, including cigarette smoking, hypertension, and obesity. These prospective data indicate that maturity-onset clinical diabetes is a strong determinant of coronary heart disease, ischemic stroke, and cardiovascular mortality among middle-aged women. The adverse effect of diabetes is amplified in the presence of other cardiovascular risk factors, many of which are modifiable.
JoAnn E Manson (Sat,) conducted a cohort in Maturity-onset clinical diabetes mellitus (n=116,177). Maturity-onset clinical diabetes mellitus vs. Without diabetes was evaluated on Nonfatal myocardial infarction and fatal coronary heart disease (RR 3.1, 95% CI 2.3 to 4.2). Maturity-onset diabetes independently increased the risk of nonfatal myocardial infarction and fatal coronary heart disease in middle-aged women (RR 3.1; 95% CI 2.3-4.2).
