Chronic kidney disease (CKD) is associated with increased cardiovascular (CV) risk. Left ventricular (LV) hypertrophy (LVH), together with coronary artery disease, has been considered the main target of intervention. LVH is highly prevalent in CKD even in early stages, as compared to general non-selected population. This is mainly due to the multifactorial pathogenesis of LVH in renal patients where both haemodynamic and non-haemodynamic stimuli synergically act inducing either an increase in left ventricular mass or an LV dilation. Anaemia and arterial hypertension seem to be the most important factors. Interventional studies have shown that partial correction of anaemia through epoetin, together with an arterial hypertension successful therapy through renin-angiotensin system acting drugs, such as ACE-inhibitors, were able to induce a LVH regression in CKD. Indeed, the unfavourable outcome in patients with both CKD and LVH, whose survival is reduced and incidence of fatal and non-fatal CV events increased, can be reversed if LVH is regressed by therapy. The most promising strategy in CKD seems to be LVH early diagnosis through echocardiography, the correct screening of risk factors, a LVM longitudinal monitoring through echo, as well as starting treatment in the early stages of CKD, with the aim of improving general and CV prognosis for these patients.
慢性肾脏病(CKD)与心血管(CV)风险增加相关。左心室(LV)肥厚(LVH)与冠状动脉疾病一起,被认为是主要的干预靶点。与一般未经过挑选的人群相比,LVH在CKD中即使在早期阶段也非常普遍。这主要是由于肾脏疾病患者LVH的多因素发病机制,其中血流动力学和非血流动力学刺激协同作用,导致左心室质量增加或左心室扩张。贫血和动脉高血压似乎是最重要的因素。干预性研究表明,通过促红细胞生成素部分纠正贫血,以及通过肾素-血管紧张素系统作用药物(如ACE抑制剂)成功治疗动脉高血压,能够使CKD患者的LVH消退。事实上,如果通过治疗使LVH消退,那么同时患有CKD和LVH的患者的不良结局(生存率降低以及致命和非致命CV事件发生率增加)是可以逆转的。CKD中最有前景的策略似乎是通过超声心动图进行LVH早期诊断,正确筛查危险因素,通过超声心动图对左心室质量进行纵向监测,以及在CKD早期阶段开始治疗,目的是改善这些患者的总体和心血管预后。
