Objective. To investigate the role of acetylsalicylic acid (ASA) in reducing the incidence of cardiovascular (CV) events in an Italian multicentre rheumatoid arthritis (RA) inception cohort. Methods. +e clinical charts of RA patients consecutively admitted to 4 Italian centres for their 1st visit from November 1, 2000, to December 31, 2015, and followed up till December 2016 were retrospectively investigated for the incidence of CV events. Patients were subdivided into two groups, namely, ASA- and non- ASA-treated groups. +e Kaplan-Meier curve and log-rank test were used to investigate differences in event-free survival. Cox regression analysis was carried out to identify factors associated with CV event occurrence. Results. Seven hundred forty-six consecutive RA patients were enrolled and followed up for a median of 5.6 years (range 2.9-8.9 years). +e incidence rate (IR) of CV events was 8/1000 person-years (p-ys) in the overall cohort. +e IR of CV events was significantly lower in the ASA-treated group with respect to the non-ASA-treated group (IR 1.7 vs. 11.8/1000 p-ys; p ? 0.0002). +e CV event-free rate was longer in ASA-treated patients than in non-ASA-treated patients (log-rank test 12.8; p ? 0.0003). At multivariable analysis, arterial hypertension (HR 9.3) and hypercholesterolemia (HR 2.8) resulted to be positive predictors and ASA (HR 0.09) and hydroxychloroquine (HCQ) (HR 0.22) to be negative predictors. Conclusion.+e IR of CV events in our Italian multicentre cohort was lower than that reported in other European and non-European cohorts. Low-dose ASA may have a role in the primary prophylaxis of CV events in RA patients.

Abstract

Objective. To investigate the role of acetylsalicylic acid (ASA) in reducing the incidence of cardiovascular (CV) events in an Italian multicentre rheumatoid arthritis (RA) inception cohort. Methods. +e clinical charts of RA patients consecutively admitted to 4 Italian centres for their 1st visit from November 1, 2000, to December 31, 2015, and followed up till December 2016 were retrospectively investigated for the incidence of CV events. Patients were subdivided into two groups, namely, ASA- and non- ASA-treated groups. +e Kaplan-Meier curve and log-rank test were used to investigate differences in event-free survival. Cox regression analysis was carried out to identify factors associated with CV event occurrence. Results. Seven hundred forty-six consecutive RA patients were enrolled and followed up for a median of 5.6 years (range 2.9-8.9 years). +e incidence rate (IR) of CV events was 8/1000 person-years (p-ys) in the overall cohort. +e IR of CV events was significantly lower in the ASA-treated group with respect to the non-ASA-treated group (IR 1.7 vs. 11.8/1000 p-ys; p ? 0.0002). +e CV event-free rate was longer in ASA-treated patients than in non-ASA-treated patients (log-rank test 12.8; p ? 0.0003).

Conclusion.+e IR of CV events in our Italian multicentre cohort was lower than that reported in other European and non-European cohorts. Low-dose ASA may have a role in the primary prophylaxis of CV events in RA patients.
