How sleep disturbance affects cardiovascular disease
March 21st is World Sleep Day. The importance of sleep to people is self-evident, and it accounts for one-third of life in terms of time alone. Good sleep helps to maintain normal physiological functions, restore energy and strength, and maintain good health. But just by looking around, we can see that people are not sleeping well. With the rapid development of society and the increasing pressure of life, the number of people with sleep disorders is also increasing significantly.
The survey found that the proportion of adults with sleep disorders is as high as 35%, and the elderly over 60 years old is as high as 57%. Among these sleep disorders, 55.5% of the patients have different degrees of social dysfunction. It is well known that cardiovascular disease also interacts with sleep disorders and is closely related. There are many kinds of cardiovascular diseases, and the overall patient population is huge. Among them, the proportion of insomnia is high, and it interacts with the primary disease, seriously affecting the quality of life and clinical outcomes of patients. Cardiovascular disease patients may experience myocardial ischemia, arrhythmia, respiratory disorders and even death during sleep. According to relevant expert statistics, about 37,500 people die suddenly at night in the United States every year, and about 88% of the sudden deaths are related to cardiovascular diseases.
When a person is in a normal sleep state, the sympathetic nerves are inhibited and the parasympathetic nerves are excited. At this time, the heart rate slows down, the blood pressure drops, and the heart load decreases, which is conducive to maintaining the stability of the cardiovascular system and thereby relieving the condition of patients with cardiovascular diseases. On the contrary, sleep disorders can cause autonomic nervous disorders, affect people's metabolism, affect both endocrine and immune systems, increase the secretion of catecholamines (especially adrenal cords), lead to vasoconstriction, increased blood pressure, faster breathing, increased metabolism, and improved The level of plasma free fatty acids and triglycerides increases the viscosity of platelets, which in turn causes a series of physiological and biochemical changes, leading to the occurrence of cardiovascular diseases such as coronary heart disease, heart failure, hypertension, and arrhythmia. A meta-analysis found that among 173,301 participants, those who slept 6 to 7 hours a day had a 7% increased risk of developing hypertension compared with those who slept 7 to 8 hours a day, and those who slept less than 6 hours a day The risk of developing high blood pressure increased by 35%.
Therefore, it is very important to pay attention to the sleep status of cardiovascular patients, but we need to remind everyone that sleep disorders are simply insomnia at night, difficulty in falling asleep, difficulty in maintaining sleep, early awakening, and no feeling of sleep after going to bed. category. If the sleep is not good, it is recommended to adjust the lifestyle. If the regular life is still not effective after a period of time, it is recommended to seek medical advice to ensure healthy sleep with the help of a doctor.
