Is high pressure 75 and low pressure 50 dangerous?

Symptoms of hypertension vary from person to person. There may be no symptoms or obvious symptoms in the early stage, and blood pressure will rise only after fatigue, mental tension and emotional fluctuation, and return to normal after rest. With the prolongation of the course of disease, blood pressure increases obviously and continuously, and various symptoms will appear gradually. This is called progressive hypertension. The common clinical symptoms of progressive hypertension include headache, dizziness, inattention, memory loss, numbness of limbs, nocturia, palpitation, chest tightness, fatigue and so on. Some symptoms are not directly caused by high blood pressure, but by higher nervous dysfunction. Dizziness and headache are the most common brain symptoms of hypertension, and most patients show persistent dullness and discomfort. Often dizziness will hinder thinking, reduce work efficiency, lack of concentration and memory loss, especially in the near future. Long-term hypertension leads to insufficient blood supply to the brain, which is also one of the reasons for dizziness. Some patients with long-term hypertension have adapted to higher blood pressure. When taking antihypertensive drugs to reduce blood pressure to normal, you will also feel dizzy because of the inadaptability of cerebrovascular regulation. When blood pressure drops too low, sometimes I feel dizzy, which is related to insufficient blood supply to the brain. Headache can be manifested as persistent simple pain or pulsating swelling pain, and sometimes even cause nausea and vomiting. Most of them are caused by the strong reflex contraction of blood vessels in the head caused by the sudden increase of blood pressure, and the pain site can be in the temple or the back of the head. Chest tightness and palpitation indicate that the patient's heart is affected by high blood pressure. Long-term high blood pressure will cause left ventricular dilatation or myocardial hypertrophy, increase the burden on the heart, and then myocardial ischemia and arrhythmia will occur, and patients will feel chest tightness and palpitation. In addition, due to brain nerve dysfunction, symptoms such as irritability, palpitation, insomnia and irritability may occur; Systemic arteriolar spasm and insufficient blood supply to limb muscles can lead to numbness of limbs and tension and soreness of neck and back muscles; It turns out that patients with vascular defect of nasal septum are prone to epistaxis. When blood pressure suddenly rises to a certain extent, there will even be severe symptoms such as headache, vomiting, palpitation and dizziness, and in severe cases, there will be confusion and convulsions. This belongs to acute hypertension and hypertensive critical illness, which often causes serious damage and pathological changes of heart, brain, kidney and other organs in a short time, such as stroke, myocardial infarction, renal failure and so on. Therefore, once the above symptoms appear, we should check and treat them as soon as possible to prevent target organ damage and hypertensive crisis or hypertensive encephalopathy. Many patients with hypertension, whether early or severe, have no conscious symptoms, and it is too late to find out when their blood pressure is measured after a stroke or other diseases. Therefore, regular physical examination to diagnose and treat hypertension at an early stage is very important for maintaining health. In addition, there is no consistent relationship between symptoms and elevated blood pressure. Patients with hypertension can't estimate blood pressure and decide the dosage of antihypertensive drugs by the severity of symptoms. According to the urgency of the disease and the progress of the course, it can be divided into slow-moving type and fast-moving type, of which slow-moving type is more common. First, progressive hypertension. (1) Early manifestations: there are no symptoms in the early stage, blood pressure occasionally rises during physical examination, or symptoms such as dizziness, headache, dizziness, tinnitus, insomnia, fatigue and inattention appear, which may be caused by mental dysfunction in the late stage. In the early stage, the blood pressure was only temporarily increased. With the progress of the disease, the blood pressure continued to increase and the organs were involved. (2) Brain manifestations: Headache and dizziness are common. Most of them are induced by emotional excitement, fatigue, climate change or withdrawal of antihypertensive drugs. Blood pressure rose sharply. Severe headache, visual impairment, nausea, vomiting, convulsion, coma, transient hemiplegia, aphasia, etc. (3) Cardiac manifestations: Early cardiac function was compensated, and the symptoms were not obvious. In the late stage, the heart function is decompensated and heart failure occurs. (4) Renal manifestations: Renal arteriole sclerosis caused by long-term hypertension. When renal function declines, it can cause nocturia, polyuria and urine containing protein, cast and red blood cells. The urine concentration function is low, and there are obstacles in phenol red excretion and urea removal. There is azotemia and uremia. (5) Arterial changes. (6) fundus changes. Second, rapid hypertension: also known as malignant hypertension, accounting for 1% of hypertension, which can suddenly change or become ill from slow hypertension. Malignant hypertension can occur at any age, but it is most common in 30-40 years old. The blood pressure is obviously increased, and the diastolic pressure is mostly above 17.3Kpa( 130mmHg), with symptoms such as fatigue, thirst and polyuria. Vision drops rapidly, retinal hemorrhage and exudation are found in the fundus, and bilateral papillae edema is often found. Proteinuria, hematuria and renal insufficiency appear rapidly. Heart failure, hypertensive encephalopathy and hypertensive crisis can also occur, and the course of disease progresses rapidly, and most of them die of uremia. Hypertension staging: the first stage: the blood pressure reaches the level of diagnosed hypertension, and the clinical manifestations are unintentional, brain and kidney damage. The second stage: the blood pressure reaches the level of diagnosed hypertension, and there are one of the following situations: ① physical examination, X-ray, electrocardiogram or echocardiography show that the left ventricle is enlarged. ② Fundus examination showed that the fundus artery was generally or locally narrowed. ③ Proteinuria or plasma creatinine concentration increased slightly. The third stage: the blood pressure reaches the level of diagnosed hypertension and has one of the following conditions; ① Cerebral hemorrhage or hypertensive encephalopathy. ② Heart failure. ③ Renal failure. ④ Fundus hemorrhage or exudation with or without optic papilla edema. ⑤ Angina pectoris, myocardial infarction and cerebral thrombosis.

What are the symptoms of hypertension and the symptoms of treating hypertension? Symptoms of hypertension vary from person to person.

Chest tightness and palpitation indicate that the patient's heart is affected by high blood pressure. Long-term high blood pressure will cause left ventricular dilatation or myocardial hypertrophy, increase the burden on the heart, and then myocardial ischemia and arrhythmia will occur, and patients will feel chest tightness and palpitation. In addition, due to brain nerve dysfunction, symptoms such as irritability, palpitation, insomnia and irritability may occur; Systemic arteriolar spasm and insufficient blood supply to limb muscles can lead to numbness of limbs and tension and soreness of neck and back muscles; It turns out that patients with vascular defect of nasal septum are prone to epistaxis. When blood pressure suddenly rises to a certain extent, there will even be severe symptoms such as headache, vomiting, palpitation and dizziness, and in severe cases, there will be confusion and convulsions. This belongs to acute hypertension and hypertensive critical illness, which often causes serious damage and pathological changes of heart, brain, kidney and other organs in a short time, such as stroke, myocardial infarction, renal failure and so on. Therefore, once the above symptoms appear, we should check and treat them as soon as possible to prevent target organ damage and hypertensive crisis or hypertensive encephalopathy. Many patients with hypertension, whether early or severe, have no conscious symptoms, and it is too late to find out when their blood pressure is measured after a stroke or other diseases. Therefore, regular physical examination to diagnose and treat hypertension at an early stage is very important for maintaining health. In addition, there is no consistent relationship between symptoms and elevated blood pressure. Patients with hypertension can't estimate blood pressure and decide the dosage of antihypertensive drugs by the severity of symptoms. Treatment of hypertension In the treatment of hypertension, we should pay attention to the principle of individualized treatment. Patients with different cardiovascular risk factors, different target organ damage and other cardiovascular diseases have different therapeutic drugs, so the principle of individualized treatment is advocated. 1. Syst-Eur and Syst-China clinical trials in elderly hypertensive patients have proved that antihypertensive therapy can reduce the occurrence and mortality of cardiovascular complications, especially stroke. Nitrendipine, a long-acting calcium antagonist, is the first choice. Systematic experimental data show that calcium antagonist therapy can reduce the risk of Alzheimer's disease in patients with isolated systolic hypertension. The STOP-2 study compared the efficacy of β -blockers, diuretics, ACEI and long-acting dihydropyridine calcium antagonists in the treatment of hypertension patients aged 70-84 years. After 4-6 years of follow-up, there was no difference in reducing cardiovascular mortality and the main end point. NORDIL test shows that diltiazem, like B-blockers and diuretics, can reduce the mortality of stroke, myocardial infarction and other cardiovascular diseases in hypertensive patients aged 50-74. Whether the elderly should be treated is still controversial, but those with extremely high blood pressure or target organ damage should be treated with drugs. At present, HYVET research is under way to evaluate the significance of antihypertensive treatment for the elderly. 2. Left ventricular hypertrophy (LVH)LVH is a compensatory response of the heart to the increase of chronic pressure or volume load. At present, the most important way to reduce LVMI is to reduce the blood pressure of hypertensive patients. ACEI or AgII receptor antagonists are preferred. Life tests have confirmed that losartan can reduce the composite endpoint of cardiovascular and cerebrovascular diseases (defined as stroke, myocardial infarction and death of cardiovascular and cerebrovascular diseases) to a greater extent than atenolol in patients with essential hypertension and left ventricular hypertrophy. 3, the treatment of heart failure should be combined with diuretics and ACEI or ARB. Diuretics can effectively improve clinical symptoms, and sufficient doses of ACEI and β -blockers have been proved to reduce the mortality of heart failure in large-scale clinical trials. 4. Lowering the blood pressure of coronary heart disease is definitely beneficial to patients with coronary heart disease, but it is necessary to avoid reflex tachycardia, increased sympathetic nervous tension and RAS activation caused by excessive hypotension. Beta blockers and ACEI are the first choice for these patients. B receptor blockers without endogenous sympathetic nerve action should be used after myocardial infarction to reduce the recurrence and sudden death of myocardial infarction. Patients with good cardiac function after myocardial infarction can use verapamil or diltiazem. 5. Cerebrovascular hypertension is the most dangerous factor for bleeding or ischemic stroke. It is generally believed that in the early stage of acute ischemic stroke, unless the blood pressure is very high, such as >: 180/ 105 mmHg, antihypertensive drugs should be stopped, otherwise excessive hypotension will obviously reduce cerebral blood flow. Blood pressure should be monitored 24 hours before thrombolytic therapy for cerebral infarction, only in SBP>；; 180mmHg, DBP> blood pressure can only be controlled by intravenous antihypertensive drugs when 105mmHg. The blood pressure of hemorrhagic stroke is obviously increased, so the intracranial pressure should be reduced first. If the blood pressure is still 200/ 120mmHg, it needs antihypertensive treatment. 6. Renal damage ACEI, ARB and CCB are all known to have renal protection. The famous AIPRI and PRIME tests show that long-term application of benazepril and irbesartan can reduce the urine protein of patients with renal insufficiency and delay the process of renal failure. Blood pressure should be below 130/85mmHg; If proteinuria > gt; 1g/d, target blood pressure 125/75mmHg. 7. Diabetes For patients with hypertension complicated with diabetes, the focus of treatment is to strictly control blood pressure below the target blood pressure. Hot research shows that the blood pressure of patients with diabetic hypertension is reduced to the lowest level (diastolic pressure
