Epidemiological evidence suggests that reducing blood pressure alone in hypertensive patients delays the onset of cardiovascular events without necessarily preventing the progression of chronic target-organ disease, such as end-stage renal failure and heart failure. Successful clinical management of hypertensive patients will therefore not be possible unless therapies are aimed both at the effective control of blood pressure and at the preservation of target-organ function. The new angiotensin II type I (AT1) receptor blocker candesartan cilexetil has been shown to be effective in reducing target-organ damage in animal models of hypertension, even at doses that do not produce significant reductions in blood pressure. Protective effects of candesartan cilexetil towards the heart and kidney have also been demonstrated in the clinical studies that have been conducted to date. Thus, candesartan cilexetil has been shown to induce regression of left ventricular hypertrophy within 8-12 weeks of treatment and to improve renal haemodynamics, both acutely and after 6 weeks of treatment in hypertensive patients. Furthermore, in hypertensive patients with co-existent non-insulin-dependent diabetes mellitus and microalbuminuria, 12 weeks of treatment with candesartan cilexetil, 8-16 mg, significantly reduced urinary albumin excretion. Clinical evidence is therefore accumulating that the antihypertensive efficacy and tolerability profile already established for candesartan cilexetil is combined with the renal and cardioprotective effects necessary for optimal management of hypertension.
流行病学证据表明,仅降低高血压患者的血压虽可延缓心血管事件的发生,但不一定能阻止慢性靶器官疾病(如终末期肾衰竭和心力衰竭)的进展。因此,除非治疗既针对有效控制血压又针对保护靶器官功能,否则高血压患者的成功临床管理将无法实现。新型血管紧张素II 1型(AT1)受体阻滞剂坎地沙坦酯已被证明在高血压动物模型中可有效减少靶器官损伤,即使在未显著降低血压的剂量下也是如此。坎地沙坦酯对心脏和肾脏的保护作用在迄今为止开展的临床研究中也得到了证实。因此,已证明坎地沙坦酯在治疗8 - 12周内可使左心室肥厚消退,并在高血压患者治疗6周后及急性治疗时改善肾脏血流动力学。此外,在合并非胰岛素依赖型糖尿病和微量白蛋白尿的高血压患者中,使用8 - 16 mg坎地沙坦酯治疗12周可显著降低尿白蛋白排泄量。因此,越来越多的临床证据表明,坎地沙坦酯已确立的降压疗效和耐受性与高血压最佳管理所需的肾脏和心脏保护作用相结合。
