Poor sleep linked to worsening of heart disease in women

Sleeping for less than six hours per night may make heart disease worse in female patients, according to a new study.

Women with coronary heart disease who sleep badly, and in particular those who wake up too early in the morning, have more than twice as much inflammation in their bodies, researchers found.

The findings suggest that poor sleep could play a greater role in raising unhealthy inflammation levels and worsening chronic conditions such as heart disease than previously thought, they said.

The study, by scientists from the University of California, San Francisco, examined the link between sleep and changes in inflammation levels in 700 older people with heart disease.

Poor sleep – usually defined as less than six hours per night – was linked to increases in inflammation in female patients during the five-year study, but not male patients.

Women who reported sleeping "poorly" or "very poorly" had 2.5 times as much inflammation as men, researchers found.
