Early hypertension may have no typical symptoms. If dizziness, nausea, vomiting, palpitation, dizziness and irritability occur, it is due to long-term poor control of blood pressure, vasospasm, peripheral vascular pulsation and vascular ischemia and hypoxia, which will lead to acute cerebrovascular disease, hypertension, crisis hypertensive encephalopathy and cerebrovascular diseases, including cerebral hemorrhage, lacunar cerebral thrombosis and transient ischemic attack of cerebral infarction. It is necessary to distinguish what are the dangerous complications of hypertension.
1. Hypertensive crisis is mostly caused by tension, fatigue and cold, pheochromocytoma attack, sudden withdrawal of antihypertensive drugs, or irregular application of antihypertensive drugs, which makes blood pressure fluctuate, arterioles appear, causing intense spasm and sharp rise of blood pressure, which will seriously affect the blood supply of important organs and produce emergency symptoms. Hypertension can occur in the early and late stages of hypertension. In a crisis, headaches, irritability and anxiety may occur.
2. Hypertensive encephalopathy occurs in patients with severe hypertension. Because hypertension suddenly broke through the scope of automatic regulation of cerebral blood flow, excessive blood perfusion in brain tissue caused brain edema. The most common manifestations may be severe headache, vomiting, disturbance of consciousness, insanity, and even coma, leading to general convulsions.
3. Cerebral hemorrhage, when the vascular pressure is relatively high, the adjustment of this buffering ability is disordered, blood vessels rupture, and serious coma and vomiting will occur for a period of time. Once this range of cerebral hemorrhage occurs after the injury of important blood vessels in the brain stem, the respiratory center will be inhibited, and vital signs and the incidence of cardiogenic shock will appear.
Once hypertension is diagnosed, it needs timely and standardized drug treatment, and regularly monitors the changes of various indicators. After hypertension is suppressed, it is not only related to the increase of blood pressure level, but also related to other cardiovascular risk factors and the existence of target organs, including hypertension, hyperlipidemia, hyperglycemia, hyperuricemia, obesity and hypercholesterolemia. In addition to reviewing the changes of blood pressure, it is also necessary to review urine routine, blood sugar, cholesterol, triglyceride renal function, blood uric acid and so on.
