A retrospective analysis of a cohort of 5210 diabetic patients revealed a mortality rate 1.3 times higher than in the general population of Warsaw. The higher death rate in the cohort under study was mainly due to an excess mortality from coronary heart disease and cerebrovascular disease. The excess mortality was greater in men than in women. Th risk of death from cardiovascular diseases was higher among the patients with early onset diabetes. Mortality from cerebrovascular disease was highest in patients treated with insulin, intermediate in the group treated with oral drugs, and lowest in the group treated only with diet. The mortality ratio from coronary heart disease in men was not related to the method of hypoglycaemic therapy given at the onset or during the course of the diabetes. In women, the highest mortality was in the group treated with insulin, intermediate in the group treated with oral agents, and lowest in the group treated with diet only.
In 1974 a cross-sectional study was conducted on 4591 out-patients (2095 males and 2496 females) aged 18-67 years, with diabetes of 1-10 years duration, and cardiovascular fatalities followed for 10 years. A multiple logistic regression was then performed on total cardiovascular deaths, deaths from ischaemic heart disease, and from stroke on selected baseline variables related to the course and control of diabetes, selected symptoms of macroangiopathy, and other risk factors, separately for insulin-treated and non-insulin-treated patients. Hyperglycaemia, proteinuria, arterial hypertension, various symptoms of ischaemic heart disease, age, and current cigarette smoking were found to be important predictors of cardiovascular mortality, more so in non-insulin-treated than in insulin-treated patients. Proteinuria and arterial hypertension carried a greater risk in females than males, but the opposite was true for the signs and symptoms of ischaemic heart disease. Relative body mass was found to correlate inversely with probability of cardiovascular death among insulin-treated males but not in non-insulin-treated males, whereas duration of diabetes was a significant factor only among non-insulin-treated females.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
