What are the early symptoms of hypertension?

According to the onset and progression of urgency, can be divided into slow progressive and radical type, in order to ease into the type.
One, chronic hypertension.
( a ): early manifestations of early asymptomatic, occasional examination found increased blood pressure, or tension, emotional or feeling dizziness, headache, fatigue, insomnia, vertigo, tinnitus, inattention symptoms such as fatigue, may be advanced mental dysfunction. Early blood pressure only temporarily elevated blood pressure rising, with disease progression, organ involvement.
( two): headache, dizziness, common brain. Much as emotional, excessive fatigue, climate change or discontinuation of antihypertensive drug induced. Rapid elevation of blood pressure. Severe headache, visual disturbances, nausea, vomiting, convulsions, coma, transient hemiplegia, aphasia and other
( three) the cardiac manifestations: early, cardiac functional compensation, the symptom is not apparent, later, cardiac decompensation, heart failure.
( four): long-term renal manifestations of hypertensive renal arteriolar sclerosis. Renal insufficiency, can cause nocturia, polyuria, urine protein, tube type and red cell. Urinary concentrating function low, phenol red excretion and urea clearance disorders. Emergence of azotemia and uremia.
( five) arterial changes.
( six) the fundus changes.
In two, malignant hypertension: also known as malignant hypertension, hypertensive disease accounts for 1%, by creep feed type sudden change and come, can also attack. Malignant hypertension may occur at any age, but to a maximum of 30-40 years old. Obvious increase of blood pressure, diastolic blood pressure in 17.3Kpa ( 130mmHg ) above, asthenia, thirst, polyuria and other symptoms. Eyesight to drop quickly, fundus retinal hemorrhages and exudates, often with bilateral papilledema. Rapid onset of proteinuria, hematuria and renal insufficiency. Can also occur due to heart failure, hypertensive encephalopathy and hypertensive crisis, in the course of rapid died of uremia.
Hypertension stage:
The first phase of hypertension: blood pressure levels, clinically inadvertent, brain, kidney damage.
Phase second: blood pressure of hypertension, and following a person physical examination, X-ray, ECG, or ultrasound heartbeat graphic left ventricular enlargement. The fundus examination, fundus artery general or local stenosis. ③proteinuria or plasma creatinine concentration increased slightly.
Phase third: blood pressure of hypertension, and one of the following persons; cerebral hemorrhage or hypertensive encephalopathy. In heart failure. Kidney failure. The fundus bleeding or exudation, with or without papilledema. ⑤angina, myocardial infarction, cerebral thrombosis.
Different populations of hypertension:
Pediatric hypertension: primary hypertension in children is rare, about 20% ~ 30%, but in recent years has increased; secondary hypertension is more, occupy 65% ～ about 80%. In pediatric patients with secondary hypertension, renal diseases accounted for 79%, followed by cardiovascular disease, endocrine diseases, neurological diseases and poisoning.
PIH pregnancy induced hypertension syndrome: namely, also ever said toxemia of pregnancy, preeclampsia, is pregnant the unique conditions, the majority occurred at 20 weeks of gestation and two weeks postpartum, accounting for about 5% of all pregnant women.
Systolic hypertension in the elderly: is 60 years of age or older with systolic blood pressure above the normal level and normal diastolic pressure, is an independent of the type of disease, is the occurrence of cardiovascular disease in the elderly and the independent risk factors for stroke, is affecting the health of the aged critical illness.
Primary and secondary hypertension:
Primary hypertension: hypertension is divided into primary and secondary two classes. In the vast majority of patients, hypertension of unknown etiology, referred to as essential hypertension, total hypertension 95% above.
Secondary hypertension: secondary to other diseases. The most common was made by renal and adrenal diseases, as well as endocrine hypertension.
