PURPOSE: To describe the clinical trial protocol that aims to evaluate the effectiveness of telenursing on lung function in patients with heart failure (HF).

METHODS: This will be a blind randomized controlled trial with parallel-group. The study area is the city of Salvador-Brazil. Salvador is the second largest metropolis in Northeastern of Brazil. The HF amounts 2.6 % of hospitalizations and 6 % of deaths from all causes in Brazil. Telenursing, in our country is still a new technology. Study sample: 156 subjects (78 per group) considering 90 % power and 12 % increase in the experimental group. Patients will be diagnosed with HF (I, II or III, according to the NYHA) and presents deteriorated lung function. The intervention group will receive health education and will be monitored for signs of exacerbation through telenursing. Telenursing consist in weekly contact, by phone, over six months with call recording. Patients has ambulatory visits monthly (V1 to V6). Groups will receive health education standard in all visits. At V1 to V6 it will be collected variables as sociodemographic, clinical of HF and pulmonary function (FEV1, FVC, FEV1/FVC , SVC , FEF 25 - 75 %), quality of life (MLHFQ), index dyspnea (Mahler), six minute walk test. There are criteria for run-in and wash-out. Statistics: descriptive, association tests and multivariate regression, intention to treat analysis. P values < 0.05 and 95% CI. The study was approved by IRB.

RESULTS: It will be suggested new technology for monitoring and preventing complications and improving the clinical management of patients with pulmonary dysfunction resulting from HF.

CONCLUSIONS: This trial may provide significant subsidies for the implementation and consolidation of lightweight technologies, contributing to new strategies, especially those that have easy implementation, potential to assist a large number of people with low cost.

CLINICAL IMPLICATIONS: The trial can help to provide earlier detection of deteriorated lung function of patients with heart failure functional and morbidity declined rates after telenursing.
