[Reproducibility of the answers of various groups of cardiovascular patients in a standardized questionnaire, differentiated by age and gender].

For the purpose of the valuation of a questionnaire developed by us for the anamnestic recognition of angiocardiopathies, which consists of 63 questions, a repeated interrogation was performed with 220 patients of different age and sex during 14 days. The average reproducibility of the yes/no-decisions was good and varied only slightly in the 8 groups of diseases (86.3--99.4%). The average degree of reproducibility referred to the sexes is nearly the same (94.7% and 95.5%, respectively). Referred to the age groups the highest reproducibility was established in the patients older than 60 years (95.7%) and the lowest in patients between 50 and 60 years (93.3%).
