Relevance. Available data do not allow to judge definitely about the relation of left ventricular hypertrophy (LVH) with high death risk and non-fatal cardiovascular complications in CHF patients. Objective. Study prognostic value of LVH in CHF patients with preserved EF. Materials and methods. Patients with CHF FC II–III with EF >45 % and LVH, confirmed by echoCG data (female >110, male >120 g / m2) were enrolled to the study. Thirteen ECG criteria of LVH were analyzed. Prospective monitoring of patients was carried out during 4 years, with analysis of lethality and hospitalization rate. Results. 56 patients (including 64 % female, mean age 74±7 лет) were enrolled to the study. From 13 analyzed ECG criteria, at leat in one case 10 criteria were LVH-positive. ECG signs of LVH (one or more) were revealed in 43 patients (77 %), more often by Cornell voltage criteria (59 %) and Cornell product criteria (46 %). Patients with these ECG signs of LVH had left ventricular mass (LVM), corrected with height, was by 16–18 % higher than in patients without these signs (p<0.015). Within 4‑year monitoring period, 47 patients (84 %) were hospitalized at least once (main reason – CHF decompensation), 6 deaths were registered (11 % lethality). According to a multifactor analysis, high values of LVM (>401 g) and age (>73 years) were associated with high death risk. ECG signs of LVH were registered in all lethal cases. At the same time lethality in high LVM group was 38 %, and with association of high LVM and at least one ECG sign of LVH, it was 50 %. Conclusion. CHF patients with preserved EF, pronounced LVH is associated with high risk of death. ECG signs of LVH allow to predict disease outcomes more precisely.
