Four out of five deaths from cardiovascular disease are due to heart attacks and strokes in
low- and middle-income countries. Early identification of risk factors in exposed individuals will help
to develop interventions that may eliminate and/or reduce these risks and prevent the development
of cardiovascular diseases. So, it is necessary to investigate the risk of impaired cardiovascular
function in university students due to the increase in some risk factors and cardiovascular events in
young adults, and to describe its epidemiology among international university students. For this,
an observational cross-sectional study through interviews is designed. The clinical validity was
addressed following the Fehring model. In addition, anthropometric data and results of laboratory
tests were collected. The nursing diagnosis “Risk of impaired cardiovascular function” showed
clinical validity, high sensitivity and specificity, as well as predictive values. Fehring ratio values were
above 0.79 and Kappa Index above 0.72. The study showed a high frequency of this nursing diagnosis
among university students, especially in students of Brazilian nationality. The main risks of impaired
cardiovascular function found in 86.8% of students were: family history of cardiovascular disease,
sedentary lifestyle, pharmacological agent, dyslipidemia, and insufficient knowledge. The most
prevalent risk factors of the nursing diagnosis in the studied population were related to insufficient
knowledge of modifiable health habits, such as sedentary lifestyle. The information provided is
expected to serve as the basis for the planning and implementation of health actions aimed at
reducing modifiable risk factors for cardiovascular disease.
