SANTOS, Mariana Alvina dos; CRUZ, Diná de Almeida Lopes Monteiro da and BARBOSA, Ricardo Luís. Factors associated to sleep pattern in heart failure patients. Rev. esc. enferm. USP [online]. 2011, vol.45, n.5, pp. 1105-1112. ISSN 0080-6234. http://dx.doi.org/10.1590/S0080-62342011000500011.
The objective of this study was to describe sleep patterns in patients with heart failure (HF) and analyze associations between sleep and the following variables: gender, age, fatigue, fatigue on exertion, physical activity, functional class, drug therapy, dyspnea, and body mass index. The nonprobability sample consisted of 400 patients (mean age 57.8 years; 64.8% were men, average schooling of 6.1 years; 82.5% Functional Class II or III). The prevalence of poor sleepers was 68.5%, and 46.5% rated sleep as poor or very poor. Scores suggest that the bad sleeper category was associated with: female, unemployed, fatigue, fatigue on exertion, dyspnea and higher functional classes of HF. The proportion of poor sleepers among patients with HF is among the highest in chronic diseases. Dyspnea and fatigue, common symptoms of this disease, significantly increase the chance of being a bad sleeper.
