Cardiovascular Risk in Rheumatoid Arthritis

Rheumatoid arthritis (RA), one of the most common inflammatory rheumatic diseases. It is defined as a chronic destructive and deforming arthropathy; it also finds its expression through systemic manifestations. RA has an undulating evolution, with remissions and relapses. Atherosclerotic cardiovascular disease represents one of the most common extra-articular manifestations of RA. It is known that the cardiovascular (CV) morbidity and mortality represent one of the leading causes of reduced life expectancy in RA. Patients with RA develop a premature and accelerated atherosclerosis, explaining the high incidence and prevalence of angina, myocardial infarction, congestive heart failure, stroke, peripheral artery disease, and the need for revascularization. Traditional risk factors (arterial hypertension, obesity, smoking, dyslipidemia, insulin resistance and metabolic syndrome, diabetes mellitus, male gender, physical inactivity) interplay with RA-related risk factors, generating endothelial dysfunction, arterial stiffness, carotid plaque, and atherosclerosis. Traditional cardiovascular risk factors alone cannot explain the increased incidence of premature and accelerated atherogenesis. Chronic inflammation, hyperhomocysteinemia, and hypercoagulation act as novel cardiovascular risk factors. Rheumatoid inflammation exerts direct effects on vessels, or by means of altered traditional risk factors. Antirheumatic drugs may promote atherogenesis or by reducing systemic inflammation may decrease cardiovascular risk. EULAR recommendations require annual cardiovascular risk assessment

N-TERMINAL PRO-BRAIN NATRIURETIC PEPTIDE IN SYSTEMIC SCLEROSIS PATIENTS: CORRELATION WITH NAILFOLD CAPILLAROSCOPY FINDINGS

Background. Pulmonary arterial hypertension (PAH) is an important cause of morbidity and mortality in patients with systemic sclerosis (SSc). This condition is diagnosed by cardiac Doppler ultrasonography, right-heart catheterization, or by serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP). The aim of this study was to assess the association between serum NT-proBNP and nailfold capillaroscopic patterns in SSc patients. We also analyzed the association between pulmonary function parameters, NT-proBNP, and nailfold capillary findings in patients diagnosed with SSc and PAH. Material and methods. We retrospectively analyzed SSc patients and healthy controls from our institution between July 2016 - December 2018. We assessed by chart review: pulmonary artery systolic pressure (PASP), forced vital capacity (FVC), forced expiratory volume in 1 sec/forced vital capacity ratio (FEV1/FVC ratio), the number of nailfold capillaries/mm and NT-proBNP. Statistical analyses were performed using the Student’s t-test, ANOVA test and the Pearson’s correlation. Results. Seventeen patients with SSc and 17 healthy controls matched for age and gender were included. Among SSc patients, 13 had diffuse cutaneous SSc (dcSSc) and 4 patients had limited cutaneous SSc (lcSSc). PAH was identified in 10 SSc patients. In SSc patients, significant correlations have been identified between PASP and NT-proBNP (r=0.9, p<0.0001), nailfold capillaries density and PASP (r=-0.95, p<0.0001), and nailfold capillaries density and NT-proBNP (r=-0.84, p<0.0001). Conclusion. We suggest that in patients with SSc, NT-proBNP is significantly correlated with PASP and nailfold capillaroscopic findings
