Clinical validation of the defining characteristics of the nursing diagnosis "activity intolerance" in patients with acute coronary syndrome.
The objective was to clinically validate the defining characteristics (CDs) of the diagnosis "Activity intolerance " in patients with ACS, hospitalized in a fourth-level care center specialized in cardiovascular health. Background: Acute coronary syndrome (ACS) is one of the main causes of morbi-mortality due to cardiovascular disease. Among the physiological findings of ACS, activity intolerance has been described. To our knowledge, this diagnosis has been validated mainly in patients with heart failure, refractory angina and other cardiovascular diseases. Design: Cross-sectional study. Patients over 18 years of age with a confirmed medical diagnosis of hospitalized ACS were included and those who were hemodynamically unstable, with alterations in the mental sphere or with communication limitations were excluded. The CDs were previously operationalized for standardized measurement and independently assessed by nurses. The prevalence of the CDs was estimated and the degree of agreement between the evaluators was evaluated with the Kappa index.
