Scientists from the Center for Cardiac Arrest Prevention (USA) report that cardiac arrest at night is more common in women than in the stronger sex.
According to statistics, of the nearly 350 thousand cases of cardiac arrest annually registered in the United States, 17-41% occur between 22:00 and 6:00. The survival rate does not exceed 10%.
Scientists have studied information on more than 3.2 thousand cases of cardiac arrest during the day and more than 900 cases when the heart stopped at night. According to the calculations, cardiac arrest in women in more than 25% occurred at night. For men, the same indicator was less than 21% of cases.
Additionally, studies have shown that people who have cardiac arrest at night are more likely to have lung disease, including chronic obstructive pulmonary disease and bronchial asthma, than people from the group of patients with cardiac arrest during the day. Also, those who had cardiac arrest at night were more likely to smoke (or were previously smokers). Finally, a third possible risk factor is the use of sedatives, pain relievers, and antidepressants that suppress breathing. Those who took these drugs were more likely to die of cardiac arrest at night.
