Abstract
In a recent issue of this Journal (2003;61:257-61) Asplund reported that in a group of elderly men and women increased nightmares were associated with an increase in irregular heart beats and spasmodic chest pain. In the description of the study, however, no definition of nightmares was presented. The conclusion of the study was based on a questionnaire survey with questions on sleep symptoms, nightmares and cardiac symptoms. As a consequence of this kind of study no conclusions can be made on the mechanism of the reported association.
