Introduction:

Cardiovascular disease is a frequent problem in patients with systemic rheumatic disorders. Patients may present with disease associated with heart disease at the time of diagnosis or at a later stage in the course of rheumatic disease.

Objective:

In the present investigation, the main objective is to determine the variables that are involved in the coronary heart disease process in rheumatic patients and the most representative factors such as: age, gender, weight in pounds, height in centimeters, income in dollars and the marital status in a group of rheumatic patients over a period of two years, treated in consultation with the Ecuadorian Social Security Institute.

Methods:

During a two-year period, a group of rheumatic patients from the IESS were consulted, consulted in a specialized cardiology consultation. Being a not very large population (105 patients), since this consultation was made only once every six months, for a period of 5 hours.

Results:

The table allows evaluating the fit of the regression model (until now, with a single parameter in the equation), comparing the predicted values with the observed values.

Conclusions:

Through a logistic equation, it was possible to determine if a patient who meets the characteristics of age and income determined, could be considered in the group that, a priori, could have coronary heart disease or not.
