AIM: Combination of cardiovascular and renal disease is currently viewed as a unified cardiorenal syndrome (CRS). The aim of our study was to assess the CRS prevalence and risk factors associated with left ventricular hypertrophy (LVH) in patients with pre-dialysis stages of chronic kidney disease (CKD) of various etiology. MATERIALS AND METHODS: We enrolled 172 patients with CKD to participate in this study. First group consisted of 83 patients with nondiabetic CKD at 2nd through 4th stage (mean age 46-15 years, 51% male and 29% female). Mean glomerular filtration rate (GFR) was 37.2 ml/min (33.9-41.4 with 95% CI); creatinine plasma clearance was 2.9 mg/dl (2.6-3.2). Second group consisted of 89 patients with type 2 diabetes mellitus (T2DM) and CKD at 1st?2nd stage (40% male and 60% female) with albuminuria (mean age 57.3-7.1 years). Duration of diabetes in this sampling was 10.4-7.1 years. All patients underwent standard clinical examination, supplemented with echocardiography to evaluate the influence of general and CKD-related risk factors for LVH. RESULTS: LVH was diagnosed in 37.3% of non-diabetic patients with CKD at 2nd through 4th stage. Aside from classic cardiovascular risk factors (including age, gender, arterial hypertension, family history of cardiovascular diseases, hypercholesterolemia), we observed the impact of kidney-related factors (anemia, plasma creatinine, disturbance of calcium-phosphorus metabolism). CKD progression was associated with elevation in the incidence of concentric and eccentric LVH). Patients with T2DM were diagnosed with LVH in 36% of cases. Increased myocardial mass correlated with plasma levels of uric acid, HbA1c, obesity and albuminuria. There was also a firm association between diabetic nephropathy, left ventricular myocardial remodelling and a history of cardiovascular events. CONCLUSION: In patients with diabetes mellitus and CKD cardiorenal syndrome develops at pre-dialysis stages due to both classic and kidney-related cardiovascular risk factors.
