American researchers claim that patients who after hospitalization with acute coronary syndrome (ACS) sleep less than 7 hours a day have worse outcomes for 1 year of observation.

Recall that previous studies have already shown a connection between chronic lack of sleep and an increased frequency of coronary events, but no one has studied a group of patients with acute coronary syndrome before.

Carmela Alcantara and her colleagues at the University of Columbia Medical Center performed an analysis of a group of 742 Pittsburgh Sleep Quality Index patients who completed the Pittsburgh Sleep Quality Index. 51% of participants slept less than 7 hours each night.

According to scientists in a letter to the editor of the International Journal of cardiology, patients with chronic sleep deprivation had a risk of hospitalization with myocardial infarction of 20.1% for 1 year compared with 14% in patients with normal sleep.

The relationship remained significant after the addition of numerous secondary factors: OR 1.52; 95% CI 1.06-2.18.

The mechanism of this relationship is still unknown..
