Core tip: sleep-disordered breathing also increases the incidence of hypertension, coronary heart disease, and cerebral thrombosis. When apnea suffocates and awakens, as well as the whole body organization organ repeatedly ischemia, the hypoxia causes the sympathetic nerve to excite, causes the peripheral blood vessel to contract, causes the blood pressure to rise. For a long time, it can increase the weight of the left heart, thicken the ventricular wall, reduce the blood volume of the heart every time, and cause coronary artery disease.
Some people snore unconsciously when they are sleeping. They think they have a good sleep when they wake up. In fact, although snoring is a common sleep phenomenon, there are huge hidden dangers behind it. Repeated snoring at night will not only cause obstructive sleep apnea syndrome, but also a series of cardiovascular diseases.
What is snoring
Snoring is a kind of sound produced by the vibration of pharyngeal soft tissue caused by the impact of airflow on narrow airway during sleep breathing, which is more common in obese, male, and elderly people.
In patients with narrow airway, the airway is kept open during the day due to compensatory contraction of pharyngeal muscles. But in sleep, the nerve excitability drops, the muscle relaxes, causes the upper airway to collapse, the airway narrows. When the airflow passes through the narrow part, it produces an eddy current and causes vibration, which results in snoring.
If the airway is too narrow, or even completely blocked, resulting in intermittent abnormal airflow at night, it will lead to sleep apnea syndrome.
(snoring can also cause disease, which needs prompt treatment)
Snoring causes hypertension
Repeated intermittent respiratory arrest, so that patients often have chest tightness at night, suffocation, sweating, limbs disorderly movement and other phenomena, seriously affecting the sleep quality, leading to daytime headache, poor energy, fatigue, drowsiness, memory loss, etc.
Sleep-disordered breathing also increased the incidence of hypertension, coronary heart disease, and cerebral thrombosis. Suffocation and waking up during apnea, as well as repeated ischemia and hypoxia of tissues and organs in the whole body, cause sympathetic nerve excitation, make peripheral blood vessels constrict, and lead to high blood pressure. For a long time, it can increase the weight of the left heart, thicken the ventricular wall, reduce the blood volume of the heart every time, and cause coronary artery disease.
If the blood oxygen is always reduced when sleeping, and the body gradually tolerates it, it will continue to decrease. When it exceeds a certain limit, it may directly turn to brain edema and asphyxia death.
Snoring and cardiovascular disease is a two-way relationship
According to the data, about 50% of the patients with sleep apnea syndrome suffer from hypertension, at least 30% of the patients with hypertension have sleep apnea syndrome, but they have often missed diagnosis and delayed treatment.
Heart failure can cause obstructive sleep apnea, and obstructive sleep apnea can also increase the burden of the heart, making heart failure more serious.
With the gradual warming of the weather, snorers are more likely to cause cardiovascular disease. If the sleep check found that the average number of respiratory arrests per hour is more than 5 times, and sleepy during the day and accompanied by hypertension, diabetes, etc., it needs treatment. If the respiratory arrest occurs very frequently, more than 15 times per hour on average, active treatment is needed even if there are no such complications.
