临床上对继发性高血压主要是治疗原发病。而高血压病的病因未明,治疗是针对其病理生理中各个环节。根据具体病情合理地使用降压药物,对于使血压维持在正常或接近正常水平,减轻症状,延缓病情进展和防止脑血管意外、心力衰竭和肾功能衰竭等并发症都有一定的作用。目前抗高血压药物种类很多,临床上存在着滥用或不合理用药的倾向,为使其合理使用,有必要把它们的作用、临床应用及注意事项等介绍一下。
Clinically for the treatment of primary hypertension is the primary disease. The etiology of hypertension is unknown, the treatment is for all aspects of its pathophysiology. Depending on the particular condition, the use of antihypertensive drugs may have a certain effect on maintaining normal or near-normal blood pressure, relieving symptoms, slowing the progression of the disease and preventing cerebrovascular accidents, heart failure and renal failure. At present, there are many types of antihypertensive drugs, and there is a tendency of abuse or irrational use of drugs clinically. To make rational use of them, it is necessary to introduce their roles, clinical applications and precautions.
