摘要：

High renin hypertension has been associated with a higher risk of stroke than low-to-normal renin hypertension. Accordingly, we investigated prospectively the prevalence of the extracranial carotid artery lesions in a case-control study of 70 patients (38 women and 32 men, aged 16 to 77 years) without history or symptoms of cerebrovascular disease. Renovascular hypertension was diagnosed in 35 patients on the basis of the angiographic demonstration of renal artery stenosis and of the favorable outcome after revascularization. It was caused by atherosclerosis in 20 patients and by fibrodysplasia in 15. Each renovascular hypertensive patient was individually matched with a control with primary hypertension for sex, race, age, blood pressure levels, duration of hypertension, smoking, diabetes mellitus, total serum cholesterol, and triglycerides. Carotid arteries were evaluated by a High Resolution Duplex system (Biosound 2000, probe 4 cm, 8 mHz). Our results show that after the matching the two groups were similar in terms of demographic features and overall cardiovascular risk profile (all P = NS). In renovascular hypertensives the prevalence of carotid artery lesions (82.6%) was significantly (P < .01) higher than in primary hypertensives (42.9%). The higher prevalence of lesions in renovascular hypertension was observed not only in patients with atherosclerosis (100% v 55% P < .001), but also in those with fibrodysplasia (57% v 27%, P < .01). Thus, for the same demographic features and overall cardiovascular risk profile, renovascular hypertension carries a more detrimental effect on the carotid artery than primary hypertension.
