CARDENAS, Claudio et al. Design of a predictive model of cardiovascular screening using decision trees: propensity of patients to present type 2 diabetes, arterial hypertension or dyslipidemia. Pilot study commune of Quellón, Chiloé. Rev Chil Cardiol [online]. 2018, vol.37, n.2, pp.126-133. ISSN 0718-8560.


: Data Mining is increasingly popular in the health field because there is a need for an efficient analytical methodology to detect unknown and valuable information of health data.


: To develop a predictive model using data mining techniques, specifically Decision Trees, to investigate patients with a propensity to develop Type II Diabetes, Arterial Hypertension or Dyslipidemia.

The data of adult patients presenting Type II diabetes, Hypertension or Dyslipidemia being followed in a preventive cardiovascular control program were analyzed with the aim of unveiling phenomena that could help develop the prediction of these risk factors.


: With respect to other decision tree algorithms, Algorithm C 5, showed a greater predictive power. The variables age and waist circumference had the greatest power of discrimination for DM2, HTA or DLP. The C 5 algorithm reached a global precision of 83.01% in the test partition. Then, in the same partition the model managed to discriminate a patient with some of the risk factors in 85.25% of cases, and to rule out any of them in 80.27% of cases.


: Data Mining, specifically decisión tree models, is a valid alternative for early detection of cardiovascular of risk factors.

Keywords : cardiovascular research, datamining; decision trees; diabetes mellitus II; hypertension; dyslipidemia.
