[Behavior of predictive variables of exacerbations of the COPD in the neumological hospital of Cuba.]

The use of predictive variables of exacerbations of the COPD is not a practice generalized in our environment, for what we cannot characterize the exacerbating patient neither to design strategies for its integral handling. There was carried out a prospective descriptive study to correlate in patient with diagnosis of COPD from the Neumologic Hospital of Cuba, with the objective of determining the association between clinical, functional variables and imagenological and the exacerbations frequency a year. The population was constituted for patients with clinical diagnosis of COPD and the sample for those patients with confirmed diagnosis that they completed the inclusion approaches. The correlation among the variables was carried out by means of the Coefficient of Correlation of Pearson with an interval of Trust of 95% and the test t student with a significance level (p) smaller than 0.05. 81.82% of the very serious patients are exacerbating with emphysema. 75% of the patients with index of the lung artery / aorta have more than two exacerbations a year. 84.61% of the patient exacerbating presented degree four of the dyspnea. The half pressure of the lung artery next to the VEF1 constituted the best exacerbations predictors in the group of studied patients.
