吸烟可导致心血管病发病率和死亡率的增高。有人提出,血浆高血压蛋白原酶活性(PRA)的增加,可能是引起高血压患者中心血管病患者死亡率上升的原因,因为吸烟时儿茶酚胺水平升高,促进高血压蛋自原酶的分泌,故死亡率的上升是PRA介导的。有人做了进一步的实验,结果表明,尽管吸烟后几茶酚胺水平提高了,但PRA并没有增 Smoking can lead to increased morbidity and mortality from cardiovascular disease. It was suggested that increased plasma proteinuria activity (PRA) may be the cause of cardiovascular mortality in hypertensive patients with cardiovascular causes, because smoking catecholamine levels, and promote the secretion of hypertensive eggs from the original enzyme, The increase in mortality is therefore PRA-mediated. Someone did a further experiment, the results show that, although the elevated levels of catecholamines after smoking, but the PRA did not increase
