Objective:

Identify nursing diagnoses in patients with myocardial infarction in hospital emergency situations, according to Orem's self-care theory.

Materials and methods:

This is a cross-sectional study that was conducted from February to August 2016 with 50 infarcted patients who were able to participate in the research. Data collection was done through an interview, using a questionnaire pursuant to the self-care theory, and the nursing diagnoses were formulated based on the NANDA-I Taxonomy.

Results:

The majority of patients were women (54%) ages 60 to 69 (34%), with family incomes ranging from one to two minimum wages (88%), with basic education (70%) and retirees (76%). There was a high frequency of arterial hypertension (62%), physical inactivity (76%) and smoking (70%). The rapid test for troponin was positive in 16 of the participants (32%). Many of the infarcted patients had self-care deficits that were indicated in 10 nursing diagnoses, particularly sedentary lifestyles (80%), physically impaired mobility (76%), and risk of activity intolerance (76%). Risk-prone health behavior and self-neglect were related to three self-care requirements.

Conclusion:

The patients needed health assistance for changes in lifestyle, comfort measures, and the realization of activity and rest.
