Mortality in relation to Minnesota code items in elderly subjects. Sex-related differences in a cardiovascular study in the elderly.

The prognostic value of electrocardiographic abnormalities has not been widely studied in the elderly. We examined the Minnesota code ECG items in 2254 elderly subjects of the Cardiovascular Study in the Elderly (CASTEL), performed on an Italian general population. In our experience, codes for ischaemia, 1st-degree atrio-ventricular block, bundle branch blocks, myocardial infarction, atrial fibrillation or sinus tachycardia were predictors of overall mortality in females, while only the former three items were predictors in men. Although ischaemia, left bundle branch block and atrial fibrillation were predictors of cardiovascular mortality in both sexes, right bundle branch block, supraventricular arrhythmias and left ventricular hypertrophy were predictors only in men, and 1st-degree atrio-ventricular block were predictors only in women. Surprisingly, left anterior haemiblock and bifascicular blocks were not predictive of mortality.
