Abstract
To identify the possible defining characteristics (DCs) and related factors of the nursing diagnosis (ND) decreased cardiac tissue perfusion. Cross-sectional study using medical charts of adults admitted to an emergency department with the chief complaint of chest pain in a hospital in São Paulo, Brazil. DCs identified: crushing chest pain, elevated markers of myocardial necrosis, ischemic electrocardiogram changes, sweating, nausea, and vomiting. Related factors identified: interruption of arterial blood flow and coronary spasm. This ND was clinically identified due to significant differences in the DCs of patients with and without the diagnosis. The clinical indicators identified in this study can be the starting point for the DCs for this ND.
