Background:Objectives:to evaluate the effect of antirheumatic therapy according to the “treat to target” strategy on the course of chronic heart failure (CHF) in patients with early RA.Methods:The study included 22 patients CHF with valid diagnosis of RA (criteria ACR / EULAR, 2010), 17 (77%) of women, median (Me) age - 60 years, Me disease duration - 7 months; IgM seropositive for rheumatoid factor 10 (45%) and / or antibodies to the cyclic citrulline peptide 22 (100%), DAS28-5.6 [4,8;6,5]. CHF verified in accordance the recommendations for the diagnosis and treatment of CHF Society of Specialists in Heart Failure (2013). The concentration of NT-proBNP was determined by electrochemiluminescence. For all patients was started methotrexate (MT) therapy with a rapid increase in the dose to 30 mg per week subcutaneously. If the MT was not effective enough, after 3 months a biological Disease-Modifying Anti-Rheumatic Drug (bDMARDs) was added to the therapy, predominantly TNF-alpha inhibitors. After 18 months, 10 (45%) patients were in remission and low disease activity, 6 (60%) of patients underwent MT therapy in combination with bDMARDs.Results:In baseline CHF with preserved EF was revealed in 21 (95%) patients, in 1 patient - CHF with reduced EF. After 18 months there was a positive dynamics of improvement of clinical symptoms, echocardiographic indicators (decrease the size of the left atrium (LА) and the index of end-systolic volume of LА, IVRT, E’ LV), diastolic function of the left ventricle (LV). There was no decompensation of CHF. LV diastolic function normalized in 7 (32%) patients who reached the target level of blood pressure, remission (n = 5) and low (n = 2) disease activity, mainly in the treatment of MT and bDMARDs. In patients with RA and CHF, the level of NT-proBNP decreased from 192.2 [151.4; 266.4] to 114.0 [90.4; 163.4] pg / ml (p <0.001), normalized in 16 of 22 (73%) patients (p <0.001) with remission or low RA activity. In 5 (22%) patients, the clinical manifestations of CHF regressed, LV diastolic function and NT-proBNP level normalized.Conclusion:In patients with early RA and CHF anti-rheumatic therapy improves the clinical course of CHF. There were an improvement in the clinical course of CHF, diastolic function of the left ventricle and a decrease in NT-proBNP.Disclosure of Interests:None declared

Background: Heart failure with preserved ejection fraction (HFpEF) is characterized by elevated left ventricular (LV) filling pressures due to impaired LV diastolic function. Low-dose infusion of angiotensin 2 (AT2) in the mouse induces a HFpEF phenotype without increasing blood pressure. AT2 infusion induces expression of Interleukin-18 (IL-18) in the heart. We therefore tested whether IL-18 mediated AT2-induced LV diastolic dysfunction in this model. Methods: We infused subcutaneously AT2 (0.2 mg/Kg/day) or a matching volume of vehicle via osmotic pumps surgically implanted in the interscapular space in adult wild-type (WT) male mice and IL-18 knock-out mice (IL-18KO). We also treated WT mice with daily intraperitoneal injections of recombinant murine IL-18 binding protein (IL-18bp, a naturally occurring IL-18 blocker) at 3 different doses (0.1, 0.3 and 1.0 mg/kg) or vehicle for 25 days starting on day 3. We performed a Doppler-echocardiography study before implantation and at 28 days to measure LV dimensions, mass, and systolic and diastolic function in all mice. LV catheterization was performed prior to sacrifice to measure LV end-diastolic pressure (LVEDP) using a Millar catheter. Results: AT2 induces a significant increase in isovolumetric relaxation time (IRT) and myocardial performance index (MPI) at Doppler echocardiography and elevation of LVEDP at catheterization, indicative of impaired LV diastolic function, in absence of any measurable effects on systolic blood pressure nor LV dimensions, mass, or systolic function. Mice with genetic deletion of IL-18 (IL-18 KO) or WT mice treated with IL-18bp had no significant increase in IRT, MPI or LVEDP with AT2 infusion. Conclusion: Genetic or pharmacologic IL-18 blockade prevent diastolic dysfunction in a mouse model of HFpEF induced by low dose AT2 infusion, suggesting a critical role of IL-18 in the pathophysiology of HFpEF.
