200.五十三歲健康男性來做高血壓評估，血壓值為 190/105mmHg，實驗室數據為 (serumpotassium 2.1mEq/L)，metabolic alkalosis (serum bicarbonate，36mEq/L)，normal renalfunction。Plasma rennin activity (PRA) is low (0.5 ng/mL per hour)，plasma aldosteroneconcentration (PAC) IS high (22.5ng/mL per hour)，the PAC: PRA ratio is 45。經過 3 天的高鹽飲食，24 小時收集尿液有較高的 aldosterone concentration (714mg/day)，請問下一步應安排何種適當的高血壓檢查?
