了解并发脑出血、脑梗死（ＣＩ）和心肌梗死（ＭＩ）的高血压患者降压药的药物利用情况。方法运用药物流行病学的研究方法，对脑出血、ＣＩ和ＭＩ患者的抗高血压药的药物利用情况进行了横断面调查。结果住院前患者所服用过的降压药中老的复方制剂居首位（７３．７％），β受体阻断剂和利尿剂占少数，分别为２３．０％和１．１％。而住院期间患者所服用的降压药则以血管紧张素转换酶抑制剂（ＡＣＥＩ）和钙拮抗剂为主，分别是４５．９％和３５．６％，而复方制剂则为８．４％。结论住院前患者所服用过的降压药中仍以老的复方制剂为主，但是与８０年代的利用情况相比有所下降。由ＪＮＣＶ所推荐的一线降压药———β受体阻断剂和利尿剂占少数；住院期间患者所服用的降压药以ＡＣＥＩ和钙拮抗剂为主 To understand the use of antihypertensive drugs in hypertensive patients with cerebral hemorrhage, cerebral infarction (CI) and myocardial infarction (MI). Methods A cross-sectional survey of drug use of antihypertensive agents in patients with cerebral hemorrhage, CI and MI was conducted using a pharmacoepidemiological approach. Results The hospitalized patients took the first place (73.7%) of the antihypertensive drugs in combination with the old ones, while the β-blockers and diuretics accounted for a minority of 23.0% and 1.1% respectively. The antihypertensive drugs taken by patients during hospitalization were mainly angiotensin converting enzyme inhibitors (ACEIs) and calcium antagonists, which were 45.9% and 35.6%, respectively, compared with 8.4% for compound preparations . Conclusions Antihypertensive drugs taken before hospitalization are still predominantly in the form of an older compound, but they have declined in comparison with the utilization in the 1980s. The first-line antihypertensive drugs recommended by JNCV --- β receptor blockers and diuretics accounted for a minority; patients taking antihypertensive drugs in patients with ACEI and calcium-based antagonists
