Acute vascular syndrome (ACS), in which the coronary arteries supplying blood to the heart become blocked by an acute clot. A study found that it was fine at the beginning of hospitalization, but gradually worsened the prognosis due to sleep disturbance.
Dr. Roland von Kannell of the University of Zurich, Switzerland, reviewed the progress of both sides and related factors for a year, and reported that women, depression, fear of death, and feelings of helplessness were the causes.
The subjects of this study were 180 ACS inpatients. As a result of analyzing their sleep disorders through an interview method, they evaluated difficulty falling asleep at night, waking up frequently, and difficulty maintaining sleep over the past month.
As a result, the rate of sleep disturbance was regarding 57% at the time of admission, 49% at 3 months, and 50% at 1 year. After adjusting for age and gender, the factors that cause sleep disturbance in the first year were women and fear of death, helplessness, and depression.
