Background:Рsoriatic arthritis (PsA) are chronic inflammatory diseases, with massive increase of cardiovascular events (CVE) and cardiovascular death. Diastolic dysfunction of the left ventricles (LVDD) is a risk factor for the development of the heart failure.Objectives:to study the effect of antirheumatic therapy administered in accordance with “Treat to target” principles on LVDD in early PsA (EPsA) patients (pts).Methods:48 (F.-23) DMARD-naive PsA pts, according to the CASPAR criteria, age 36[27; 45] years (yrs.), PsA duration – 6[4; 8] months. All pts were assessed for transthoracic echocardiography. Diastolic function was determined by early and atrial peak filling rates derived from differential volume-time-curve analysis. Methotrexate therapy was started in all pts with an escalation of the dose up to 25 mg/week subcutaneously. In case of no remission 3 months later, MT was added with biologic therapy: Adalimumab, Certolizumab pegol, Ustekinumab. Antihypertensive therapy received all pts with arterial hypertension (AH). All p less then 0.05 considered to statistical significance.Results:At baseline LVDD was identified in 5(10.4%). The LVDD pts were older, in more cases they had AH, abdominal obesity (p<0.05). Significant negative correlations were found between LVDD and body mass index (BMI) (r=-0.41), age (r=-0.71), total cholesterol (r=-0.44), triglycerides (r=-0.48), low density lipoproteins (r=-0.44), systolic (r=-0.59) and diastolic blood pressure (r=-0.4), for all p<0,01. By 18 months of therapy significantly decreased DAS from 4.06[3.48; 4.91] to 0,97[0,65;1,48]; C-RP from 19.4 [8.8;37.5] to 2.2 [0.9; 4.6]mg/l, for all p<0,001. DAS remission was achieved in 69% of pts. We didn’t find significant differences between baseline and after treatment the frequency of LVDD – 5(10,4%) to 4(8.3%).Conclusion:in pts with EPsA frequently (10.4%) were detected LVDD, which are associated with a АН, age, higher BMI. Low prevalence LVDD in patients with EPsA is possibly caused by short duration of disease and early start of antirheumatic therapy. This has implications for development of preventive strategies for heart failure in EPsA patients.Disclosure of Interests:None declared
