On 226 diabetics at the age of greater than or equal to 40 years the prognostic evidence of the ECG after resting using the Minnesota code was prospectively analysed with regard to the life expectancy in the subsequent 10 years. During this period 65 diabetics died, 46 of them of vascular and 19 of another cause of death. Essential results of the analysis are Diabetics with Q/QS types (code 1.1-1.2) as well as repolarisation disturbances (code 4.1-4.3/5.1-5.3) in the ECG showed a higher lethality rate in the observation period (48.8%) than those ones with an ECG unsuspicious of ischaemic heart disease (15.9%). When a hypertension is simultaneously present the prognosis is additionally loaded. The proportion of ECG-findings suspicious of ischaemic heart disease was initially only 62.3% in diabetics with coronary cause of death. A relation between codation pattern and year of death in a temporary interval to the ECG-registration could not be established.
