Electrocardiographic predictors of five-years mortality in chronic obstructive pulmonary disease patients

Introduction/Objective. Cardiovascular disease is one of the most common comorbidities among subjects with chronic obstructive pulmonary (COPD). The aim this study to evaluate electrocardiogram (ECG) parameters and mortality predictors in COPD patients. Methods. A total 835 consecutive patients were included. classified suffer from if forced expiratory volume first second (FEV1) vital capacity (FVC) was < 70% three postbronchodilator measurements. following ECG changes observed: axis, P wave, low ORS complex, transitional zone, left bundle branch block (LBBB), right (RBBB), incomplete RBBB, S1S2S3 configuration, negative T V1?V3. followed up for over a five-year period. Results. Both survivors non-survivors similar age, sex, status. FVC FEV1, as well Global Initiative Chronic Obstructive Lung Disease stadiums significantly higher survivor group (p 0.016, p 0.001, respectively). Normal axis percentage non-survived = 0.020). RBBB are more frequent findings who died 0.05, LBBB, configuration present In multivariable logistic model, LBBB have two times chance compared without LBBB. contrast, 1.6 lower having death outcome. Conclusion. main patients? but according statistical should be further explored possibly obligatory involved routine clinical practice an easy low-cost screening method.
