目的在高血压人群中进行原发性醛固酮增多症(原醛症)患病率的筛查。方法抽取就诊患者立位2小时静脉血查血浆醛固酮与血浆肾素之比(ARR),若ARR大于30,进一步行肾上腺CT检查或卡托普利试验,以确定原醛症的诊断。结果 817例患者中,诊断为原醛症的31例,占3.8%,伴有低钾者占65%,血钾正常者占35%。结论 ARR是针对高血压人群进行原醛症筛查的有效指标,可提高原醛症的检出率,我国原醛症患者仍以低钾占多数。 Objective To screen the prevalence of primary aldosteronism (primary aldosteronism) in hypertensive population. Methods The plasma aldosterone and plasma renin ratio (ARR) were determined 2 h after venous blood was taken from the patient. If the ARR was greater than 30, adrenal CT or captopril was further performed to confirm the diagnosis of primary aldose. Results Among the 817 patients, 31 cases were diagnosed with primary aldehyde disease, accounting for 3.8%, those with hypokalemia accounting for 65% and those with normal serum potassium accounting for 35%. Conclusions ARR is an effective index for the screening of primary aldosteronism in hypertensive population, which can improve the detection rate of primary aldehyde disease.
