[Mortality risk factors in cardiovascular diseases in patients with diabetes mellitus in Warsaw--a 10-year prospective study].

A prospective study was made in the years 1973 through 1983 on mortality among 4591 patients (2095 men and 2469 women) with usually noninsulin dependent diabetes, of 1-10 years duration. The anamnestic data and examination parameters obtained during a cross-sectional investigation served as the prognostic changeables (risk factors) to assess the mortality due the most frequent circulatory diseases. The applied model of the logistic regression allowed an attempt of the assessment of their independent effect. Analysis regarding the sex and the methods of diabetes treatment was done in four groups of mortality causes classified according to the VIII Revision of the International Classification of Disease. Injuries and Causes of Death: 1. Cardiovascular system diseases. 2. Ischaemic heart diseases. 3. Other diseases of the cardiovascular system. 4. Vascular diseases of the brain. The quantitative and qualitative effect of the arbitrarily chosen factor of death risk was of varying importance and was related to the sex and the methods of the hypoglycemising treatments. The effect of ageing was an independent factor of death risk among all analysed causes of mortality in both sexes independent from the methods of the hypoglycemising treatment with the one exception of women treated with insulin who died of stroke. Generally however, the ageing factor showed a greater prognostic value in patients treated with insulin. Hypertension, especially if marked, showed to have the most prognostic value among the all analysed factors of death-risk especially in patients on oral antidiabetics. The risk in this group was due mainly to the cerebral stroke, to a lesser degree to the "other" diseases of the circulatory system, and to the all diseases of the circulatory system but to the least degree it was related to the ischaemic heart disease, in both sexes. Among insulin treated diabetics the hypertension was a death-risk of most importance in men usually due to the vascular brain disease and other diseases of the cardiovascular system but to a lesser degree to the circulatory diseases, as a whole. In women however the marked hypertension increased the death-risk in patients with coexisting circulatory disease, not a particular one, but as a whole. Albuminuria had a pronounced prognostic value, especially if massive, in both types of diabetes, mainly, however, among women who died of any cardiovascular causes.(ABSTRACT TRUNCATED AT 400 WORDS)
