Hypertension is one of the common chronic diseases and a major risk factor for cardiovascular health in middle-aged and elderly people. Many cardiovascular and cerebrovascular diseases such as: myocardial infarction, coronary heart disease, cerebral infarction , cerebral hemorrhage are all related to this high blood pressure. Data survey shows that there are nearly 300 million hypertensive patients in my country, of which more than 90~95% are essential hypertension patients
Most scholars believe that long-term hypertension can cause cerebral arteries to develop. glass-like degeneration , the elasticity is reduced and the brittleness is increased. Loss of vascular wall tension and fibrinous necrosis result in local arteries that appear as spindle or spherical aneurysms under the impact of blood pressure, and blood can also invade the vessel wall to form dissecting aneurysms. When blood pressure rises suddenly, the aneurysm ruptures causing bleeding. Hypertension can also cause spasm of cerebral arterioles, leading to ischemia, hypoxia, necrosis, and hemorrhage of distal cerebral tissue.
Hypertensive intracerebral hemorrhage is one of the most serious complications of hypertension, often occurs in 50 to 70 years old, slightly more male, prone to occur in winter and spring, especially those with hypertension or obvious arteriosclerosis. Patients with cerebral hemorrhage often have a sudden onset of due to emotional agitation and sudden exertion. If the treatment is not timely, the early mortality rate is very high. Most of the survivors have different degrees of movement disorder, cognitive impairment, Sequelae such as speech and swallowing disorders.
Men's high blood pressure is uncontrolled after meals Smoking Sudden cerebral hemorrhage
Case: Patient xxx, male, 46 years old, has a history of hypertension for 10 years, the blood pressure was slightly high in the past, and he did not pay attention to it. Later, the blood pressure continued to rise. drug control. But there is a bad habit of smoking after meals.
Recently, the patient walked to the balcony to smoke after eating one day. Halfway through the cigarette, he suddenly felt a severe headache. He rested on the sofa for a period of time, but did not relieve. Furthermore, and limb weakness appeared. The patient is sent to the hospital for treatment. After a preliminary examination, it was found that the blood pressure was as high as 180/97mmHg, was confused and , and the doctor initially considered it as a brain lesion. Immediately do CT examination , diagnosed as cerebral hemorrhage. After rescue, the bleeding point was controlled, and then sent to ICU for follow-up treatment.
Doctors said that hypertensive cerebral hemorrhage often occurs in 50 to 70 years old. It usually occurs during activities and emotional agitation. There is no warning before the bleeding. Half of the patients have headache and are very severe. Vomiting is common, and blood pressure rises significantly after hemorrhage. Clinical symptoms often peak within minutes to hours. Hemiparesis caused by hemorrhage in the basal ganglia, thalamus and internal capsule is a common early symptom; epileptic seizures occur in a few cases, often focal; severe cases quickly turn into confusion or coma.
Patients with high blood pressure, despite taking medicine, smoking after meals, resulting in poor blood pressure control, and even large fluctuations , resulting in cerebral vascular rupture and hemorrhage. As the saying goes, "a cigarette after a meal is better than a fairy", but in fact, a cigarette after a meal may seriously endanger human health and even life. Because when we are full, a lot of blood in the body is concentrated in the stomach, and the blood circulation is also more active at this time. The harmful substances in cigarettes will also be over-absorbed, thereby stimulating the body's blood vessels and nerves, resulting in unstable blood pressure. resulting in cerebral hemorrhage.
What are the main factors of essential hypertension?
1. Genetic factors. In all patients with essential hypertension, nearly 60% have a family history, and nearly 30-50% have a genetic background.Studies have shown that polygenic inheritance of is an important factor causing family aggregation of hypertension. The long-term common living environment, diet, etc., are also the reasons for the gathering of high blood pressure families;
2, long-term smoking. Cigarettes can increase blood pressure. Because cigarettes contain " nicotine ", it not only makes the brain dependent and addicted. Nicotine also stimulates the adrenal glands to release a large amount of catecholamine and adrenaline , causing abnormal contraction and spasm of their own blood vessels, and increased heart rate. Over time, the smooth muscle of the arteriolar wall degenerates and the intima of the blood vessel gradually thickens, eventually developing into hypertension and arteriosclerosis. Data shows that smoking a cigarette a day increases systolic blood pressure by 10-30mmhg;
3. Alcoholism. Studies have shown that a small amount of long-term drinking can cause a mild increase in blood pressure, and excessive drinking can lead to a significant increase in blood pressure. Although alcohol will cause a short-term drop in blood pressure during the process of metabolizing in the body, this is mainly related to the property of alcohol to dilate blood vessels. However, when the alcohol is completely metabolized, blood pressure rebounds again. At the same time, alcohol will also cause damage to the vascular endothelium, and then induce hypertension, atherosclerosis ;
4, high-sodium diet. In fact, it is the sodium ion contained in the salt that causes the blood pressure to rise. Excessive intake of any high-sodium food will cause metabolic burden on the kidneys, resulting in the accumulation of a large amount of sodium ions in the body, which will gradually develop into water and sodium retention, increased blood volume, and fluctuations in blood pressure. In addition to salt, all kinds of condiments, potato chips, instant noodles, noodles, cakes, etc. are high-sodium foods and should be eaten less;
5. Emotional instability. Emotions can affect changes in high blood pressure. For example, long-term life pressure, excessive mental stress, and severe mood swings can cause blood pressure fluctuations. Because emotions interact with endocrine and neurological functions.Severe mood swings will stimulate the massive secretion of , angiotensin and , leading to rapid heartbeat and vasodilation. Repeated action will develop into abnormal arterial vasospasm and increased blood pressure. Studies have shown that blood pressure generally rises after meals. If you are emotional and irritable at this time, it will induce an increase in blood pressure, resulting in abnormal contraction of blood vessels in the brain and accelerating the occurrence of cerebral hemorrhage.
6. Cold stimulation. Cold weather can lead to increased blood pressure through multiple mechanisms: it can activate the sympathetic nervous system and the renin-angiotensin-aldosterone system, causing peripheral blood vessels and skin vasoconstriction, heart rate to increase, thereby increasing blood pressure; inhibiting dilation Vascular substances such as nitric oxide generate, promote blood pressure; activate the endothelin system in the body, help to increase blood pressure. Especially when the cold air is suddenly inhaled, it will cause coronary artery spasm, which can easily induce the occurrence of angina pectoris, myocardial infarction and aortic dissection. Cold stimulation can also induce stroke.
In addition, the blood of the human body is concentrated in the stomach after a meal. If you take a bath immediately after a meal, the blood vessels of the human body will expand rapidly, but the blood cannot keep up, which will cause great pressure on the blood vessels and increase the burden on the heart. Fall in a coma and cause cerebral hemorrhage .
