AB0435 CAPILAROSCOPY DOES NOT PREDICT CARDIOVASCULAR EVENTS IN PATIENTS WITH SYSTEMIC SCLEROSIS: A RETROSPECTIVE STUDY

Background: Systemic sclerosis is associated with increased risk of cardiovascular disease (CVD) (1) and studies using MRI suggest that microvascular disease has an important role (2). Capillaroscopy is a non invasive and safe technique that assesses peripheral microvascular damage (3). Objectives: The objective of this study was to evaluate the predictive value of the capillaroscopy in relation to major adverse cardiovascular events (MACE). Methods: Retrospective study with three timepoints (at baseline, at 5 and 10 years) including patients with scleroderma from EUSTAR center 096. Data were collected from the registry and observation papers. We performed capillaroscopy to all patients at the time of inclusion in the EUSTAR registry (2004) and at baseline (2009). Also, CV risk scores were calculated at baseline and were reassessed at 5 and at 10 years using the SCORE calculator. Risk score was considered low if was between 0 and 2, moderate 3-9 and high >10. The relation between capillaroscopy and MACE was tested in using bivariate regression. Results: Of 22 patients, mean (standard deviation (SD)) age was 43.1 (11.5), all patients were females, mean (SD) disease duration was 5.4 (4.5). During the 10 years of follow up, 5 (22.7) patients had been lost of follow up and 8 (36.4) patients had died. Only 9 (40.9) patients completed the 10 year follow up. At the time of inclusion in the EUSTAR, one patient showed early scleroderma pattern at capilaroscopy, 15 had active pattern and 6 patients had late pattern. Capillaroscopic scoring showed 2 (9.1) patients with disarranged ( 50%) aspect, 4 (18.2) patients with local paucity, 10 (45.5) patients with enlarged loop bordering local paucity and 1 patient (4.5) with complete paucity. Capilaroscopy at baseline showed active pattern in 4 patients and late pattern in 18 patients. Thus, 13 (59.1) of patients had a progression of the disease at capilaroscopy before follow up. At baseline, 14 (63.6) patients had traditional CV risk factors. Cardiovascular risk scores found 21 (95.5) patients with a low risk score and 1 (4.5) patient with a moderate risk score. At 5 years 11 (0.5) patients had a low risk score and 1 (4.5) patient had moderate risk score and at 10 years, 5 (22.7) and 2 (9) patients had low and moderate risk scores, respectively. We found 6.2 MACE/100 patient-year and 5.5 deaths/100 patient-year. Capillaroscopy (p=0.684), disease progression on capillaroscopy (p=0.781), capillaroscopic scoring (p=0.92) and CV risk score (p=0.98) were not predictive factors of MACE. Conclusion: Patients with systemic sclerosis are at high risk of MACE and traditional CV risk scores underestimate this risk. Changes/progression on capilaroscopy is not predictive for MACE. However, this hypothesis needs to be tested on a bigger cohort.
