妊娠期血压升高,常与三种病情相关。一是妊娠高血压综合征,亦称妊娠中毒症;二是妊娠合并原发性高血压病;再是妊娠合并肾性高血压。后两种病情常与妊娠高血压综合征复合存在。凡血压升高,无不与内分泌激素中升压物质的消长有关,妊娠期血压升高亦然。兹分述于下。一、妊娠高血压综合征的基本病理生理改变是全身小动脉痉挛,特别是直径在200μm以下的小动脉,尤易发生。各种高血压疾病的共同特点是血管壁对血管紧张素和去甲肾上腺素的敏感性增高,而 High blood pressure during pregnancy, often associated with the three conditions. First, pregnancy-induced hypertension, also known as gestosis; second pregnancy complicated with essential hypertension; then pregnancy with renal hypertension. The latter two conditions often complicated with pregnancy-induced hypertension syndrome exist. Where the blood pressure, all endocrine hormones are related to the rise and fall of substances in the blood pressure, elevated blood pressure during pregnancy is also true. It is divided below. First, the basic pathophysiological changes of pregnancy-induced hypertension syndrome is systemic arteriole spasm, especially the arterioles with the diameter less than 200μm, especially prone. A common feature of various hypertensive disorders is the increased sensitivity of the vascular wall to angiotensin and norepinephrine while
