The question was whether anxiety, heart rate and skin conductance level just before invasive cardiac procedures could be predicted by anxiety related measures obtained at patients homes approximately 3 weeks before treatment. Trait measures of avoidant coping and defence were provided by sixty-three male and thirty-three female patients who were scheduled for a diagnostic or interventional heart catheterization. In hospital physiological measures were registered continously during a 20 min interview and subsequently patients reported their anxiety. Results with hierarchical regression analysis showed that sex, age, medical variables and state anxiety at home explained 62% of state anxiety in hospital. Female sex predicted high anxiety in hospital while advanced age predicted low anxiety. Medical variables and measures of coping and defence did not add a significant contribution to this prediction of anxiety. Skin conductance and heart rate measures could not be predicted by the psychological measures collected at home.
