It is a research developed at a University hospital, aiming to identify the prevalent stressors to patients which procedure heart disease submitted to a PTCA and a MRC. To collect data it was used a questionnaire to identify the patients on pre procedure to characterize the population; and the Intensive Care Unit Environmental Stressor Scale (ICUESS) on post procedure. To analyse the data is was obtained the average values attributed to each one of the items, ranking it, whatever the higher the average the strongest were the stressors intensity. To compare these results obtained from ICUESS between the groups (PTCA and MRC), it was chosen the chi-square test and the no-parameter Kruskall-Wallis test. The meaning level was 5%. The main stressors identified in both groups were: having pain, unknown sounds and noises, listening the equipment noise and alarm.
