Staying up late every day is not a good habit, on the basis of organic diseases, it may increase the risk of sudden death, especially for patients with coronary heart disease, because staying up late every day can cause increased sympathetic excitability, increased secretion of hormones such as catecholamines in the blood, which can easily induce instability of coronary plaques, causing atheromatous plaque rupture, leading to platelet aggregation to form thrombus. Myocardial ischemic necrosis occurs when the thrombus blocks the coronary artery, thus causing acute myocardial infarction. On the basis of acute myocardial infarction, malignant ventricular arrhythmias, such as sustained ventricular tachycardia and ventricular fibrillation, can occur, leading to sudden death. Therefore, you should avoid exertion, ensure sufficient sleep and have a regular life in order to benefit your physical and mental health and prevent the occurrence of cardiovascular and cerebrovascular events that can lead to adverse consequences.
