Associations of heart failure with sleep quality: the Rotterdam Study.

ABSTRACT:

Study objectives

The prevalence of sleep disturbances and heart failure increases with age. We aimed to evaluate the associations of incident heart failure and cardiac dysfunction with changes in sleep quality.

Methods

This prospective population-based study was conducted in the Rotterdam Study. Of the 3445 eligible persons (mean age 72.0±7.1 years) available for cross-sectional analyses, 8.9% (n = 307) had prevalent clinical heart failure. In longitudinal analyses, 1989 eligible persons (mean age 70.0±5.8 years) were followed for an average of 6.5±0.4 years, of which 4.6% (n = 91) had prevalent or incident clinical heart failure. Heart failure was assessed according to European Society of Cardiology criteria. To estimate cardiac function, we measured left ventricular fracti
