高血压重症度的分类标准,原则上应考虑血压值的高低及脏器受累的程度。实际上早有许多标准遵循了这一原则,如主要靠眼底所见进行分类的Keith—Wagener—Barker标准就是根据重要脏器的功能及心血管系统的肥大、硬化所见、血压值、临床经过及预后等综合考虑而制定的。但是,血压的高低与脏器受累程度不一定成正比,将纯属高血压所致的各脏器的血管性障碍单独抽出进行判定,实际上是困难的,尤其是动脉硬化的改变,有高血压性的,也有与血压值无关的代谢性因素、环境因素及遗传素质等影响而形成的。因此在判定高血压性脏器受累程度时,存在着不少因这些因素所致异常的病例,而将这些异常病例一个个截然分开是很困难的。具有动脉硬化性改变所致脏器受累的病人,与高血压脏器受累同样,在实际血压的管理及预后判定上都是重要的考虑对 Hypertensive severity of the classification criteria, in principle, should consider the level of blood pressure and organ involvement level. In fact, many standards have followed this principle. The Keith-Wagener-Barker standard mainly classified by the fundus is based on the function of vital organs and the hypertrophy and hardening of the cardiovascular system. The values ​​of blood pressure, clinical experience And prognosis and other comprehensive consideration to develop. However, the level of blood pressure and organ involvement is not necessarily proportional to the purely due to hypertension caused by the vascular disorders of each organ alone to judge, in fact, difficult, in particular, changes in arteriosclerosis, high Blood pressure, but also has nothing to do with the blood pressure value of metabolic factors, environmental factors and genetic factors such as the formation of. Therefore, in determining the degree of hypertension involved in the degree of existence, there are many cases of abnormalities caused by these factors, and these abnormal cases one by one is very difficult to separate. Patients with arteriosclerotic changes that are involved in organ involvement are also important considerations in the management and prognosis of true blood pressure, as are those involved with hypertensive organs
