What is high blood pressure, what are the characteristics?

Hypertension is the arterial blood pressure more than normal exception:

Normal blood pressure: diastolic pressure = < 85mmHg, systolic pressure = < 130mmHg

Normal value: diastolic pressure 89mmHg, 85-130-139mmHg systolic blood pressure

Hypertension: the diastolic pressure > = 90mmHg, systolic pressure > = 140mmHg

Incidence of hypertension in combination with the following:

(1) prevalence is higher from the onset in all regions of the world, the developed Western countries was higher than that of developed countries and regions in Western countries the prevalence of 20%, China's average prevalence of 11.8%. From the last two years of data has increased each year trend. It was in November 1994, held in Beijing in October the second Conference on hypertension, hypertensive Union President Liu Li, Professor released the latest figures, currently about 90 million people suffering from hypertension, only Beijing 20 million, of which the critical and mild hypertension accounted for around 60%.

(2) the pathogenetic characteristics from the data show that China's hypertension has the following characteristics: ① brain workers higher than manual workers. ② the North over the South region. ③ cities than in rural areas. ④ family history, family-centered goals with high blood pressure than non-family with hypertension. ⑤ high salt diet is higher than the low-salt diet. ⑥ are tobacco and alcohol-free wine devotees higher devotees. ⑦ overweight are higher than those of normal weight. ⑧ long term stress are higher than for other workers.

(3) serious complications from the performance of hypertension, early symptoms often not obvious, even without any feeling. In General, the patient only has a headache, neck, back of tight, sleep sleeping dizziness well, forgetful, also has the appearance of symptoms such as chest tightness, palpitation. But when a rapid rise in blood pressure, severe headache, nausea and vomiting, and even syncope. As a condition of development, gradually appear to undermine the main organ of complications, such as coronary artery disease, cerebral arteriosclerosis, stroke, kidney disease, arteriosclerosis, etc, these are the advanced performance of hypertension.

(4) prevention and treatment of hypertensive patients long treatment and preventive measures, but is a long-term process of treatment and prevention. It can be said that a person suffering from hypertension, medication and prevention will be accompanied by a lifelong. Therefore, if suffering from hypertension, must establish long-term treatment and long-term prevention of thought. Experts with years of experience, in essential hypertension patient, long-term adherence to antihypertensive therapy, blood pressure control in normal or basic normal levels, in order to efficiently control and reduce complications. The first is the treatment of secondary hypertension primary disease, in order to better control of hypertension.
