Effects of mineralocorticoid receptor antagonists on left ventricular mass in chronic kidney disease patients: a systematic review and meta-analysis
Tóm tắt
Mineralocorticoid receptor antagonists (MRAs) are used widely in treatment of heart failure, but their effects on cardiovascular complications and mortality of chronic kidney disease (CKD) are not well known. Thus, we aim to assess such therapeutic effects of MRAs on CKD. Electronic literature published in any language until Dec 31, 2015, was systematically searched on PubMed, Embase, and Cochrane Central Register of Controlled Trials. Primary outcome was left ventricular mass (LVM) or LVM index (LVMI), and secondary outcome was all-cause mortality and major adverse cardiovascular events (MACEs). Results of continuous outcomes were pooled using mean difference (MD) and standard mean difference (SMD). Risk ratios (RRs) with 95 % confidence intervals (CIs) were pooled using a random- or fixed-effects model. Totally 12 studies (6 randomized controlled trials with 1003 participants) involving 4935 patients were included. MRA treatment versus non-MRA treatment resulted in a significant change of 0.93 SMD (standard mean difference) in LVM (LVMI), a significant reduction of 22 % in all-cause mortality, a significant reduction of incidence of MACEs (RR 0.65, P = 0.001), significantly higher prevalence rates of hyperkalemia (>5.5 mmol/L), but no significant change in prevalence rates of severe hyperkalemia (>6.0 mmol/L). MRA benefits CKD patients in terms of LVMI, all-cause mortality, and MACEs with no incidence of severe hyperkalemia. Nevertheless, the real effects of MRAs on cardiovascular events and mortality as well as their safety in CKD patients should be identified by further studies with prospective and large-sample clinical trials.
