Regular sleep schedule linked to better results after heart failure

People who recover from heart failure should consider improving the regularity of their sleep. Moreover, suggests a study by Oregon Health & Science University.

The research team revealed that even sleeping sleeps that are moderately irregular doubles the risk of having another clinical event in the six months. For example, according to a study published today in the journal Avances Jacc. However, A clinical event could be another visit to the emergency room, hospitalization or even death.

“Going to bed. In addition, waking up at coherent moments is important for global health,” said the main author Brooke Shafer, Ph.D., deputy research professor in the Ohsu School of Nursing. Consequently, “Our study suggests that the coherence of the sleep moment can be particularly important for adults with heart failure. Meanwhile, »»

The researchers regular sleep schedule linked better registered 32 patients who had been hospitalized for acute heart failure in Ohsu hospital. the Hillsboro Medical Center from September 2022 to October 2023. For a week after driving the hospital. the participants used sleep newspapers to record the time when they fell asleep at night, woke up in the morning and at the time of the tables taken during the day.

Participants were then classified as regular sleeping or moderately irregular sleepers, depending on their sleep habits.

The study revealed:

• After leaving the hospital, 21 participants experienced a clinical event in six months.
• From this group, 13 were classified as moderately irregular sleeping in relation to eight classified as having a regular sleep schedule.
• Statistically, irregular sleepers had more than double the risk of an event over the duration of six months.

The increased risk of a clinical event for moderately irregular sleepers has remained even when regular sleep schedule linked better it is taken into account of possible contributory factors such as sleep disorders. other underlying medical conditions. The research team says that the study is among the first to examine the impact of the regularity of sleep in the context of heart failure. and the results are added to an increasing number of evidence suggesting the importance of maintaining a regular sleep calendar.

“Improving the regularity of sleep can be a low -cost therapeutic approach to alleviate adverse events in adults with heart failure. ” conclude the authors.

Shafer said the results strengthen the link between sleep regularity and cardiovascular health.

“When we sleep. in a state of rest, our blood pressure and our heart rate decrease compared to daytime levels,” she said. “But the variability of the sleep moment can disrupt the mechanisms involved in the regulation of the cardiovascular system. Irregular sleep can contribute to undesirable results, especially regular sleep schedule linked better for people already affected by heart failure. »»

The next step would be to extend research to a greater cohort of participants. to see if the improvement in the regularity of sleep reduces the risk of another clinical event, she said.
