Rheumatoid arthritis (RA) affects 0.5-1% of general population. The number of cardiovascular (CV) events in patients affected by RA is 2-3 times higher compared to subjects not affected by RA. Atherosclerosis is the initial sign of CV affection in RA patients, followed by cardiovascular and cerebrovascular events. Main CV risk factors in RA are: arterial hypertension (HA), dyslipidemia, diabetes mellitus (DM). Glucocorticoids induce hyperglycemia and insulin resistance. HA is correlated with the incidence of stroke, heart failure, and kidney diseases. Dyslipidemia is a complication of RA. CV events are: acute myocardial infarction (AMI), heart failure (HF), revascularization interventions, atrial fibrillation (AF) and strokes. AMI is the most common event. Another complication is cardiac insufficiency. Chronic inflammation plays an important role in the development of HF and AF. AF is the principal cardiac arrhythmia in the general population, with a higher incidence in RA subjects; it is the main reason for stroke, with stroke risk being higher in RA patients. Aim of the study: estimate the rate of incidence of CV events in RA patients, estimate the frequency of HA, DM, dyslipidemia, evaluate the correlation between CV risk factors and CV events in RA patients in comparison with the general population in Lombardy. The study design is: cohort, retrospective based on data extracted from health databases (AHD) from Lombardy Region between January 1st 2004 and December 31st 2013. Patients were selected applying the algorithm from the study RECord linkage on Rheumatic Diseases, thus identifying 70,061 RA patients. Subjects affected by CV events between January 1st 2004 and December 31st 2008 were not considered. 20,965 RA subjects and 245,933 non RA subjects were identified. 1,880 subjects of RA subjects presented at least one cardiovascular event. Our analysis confirms a significantly higher incidence for AMI, HF, and AF in RA subjects; the incidence of ischemic stroke shows no difference. Prevalence of HA and DM is higher in RA subjects in comparison with not-RA subjects (38.63% vs 34.29%, p value <0.001 / 9.03%>8.52%, p value 0.012). The prevalence of dyslipidemia is lower in RA subjects than not-RA subjects (15.11% vs 16.16%, p value <0.001). It is to be considered that cholesterol levels are reduced in high activity RA. RA is associated with an increased incidence rate (p<0.001) of AMI (49%), HF (51%), AF (26%). A similar increase of HF and AMI is observed in DM (61% and 53% respectively). No increase of stroke incidence was observed in RA patients. HA is the cardiovascular risk factor determining the highest increase of incidence rate of AF and HF, doubling the rate. In Lombard population, RA represents an independent risk factor for cardiovascular events.

L’Artrite Reumatoide (AR) interessa lo 0.5-1% della popolazione. Il numero di eventi cardiovascolari (CV) nei pazienti con AR è 2-3 volte maggiore rispetto alla popolazione generale. La sofferenza del sistema cardiovascolare nei pazienti affetti da AR si esprime con l'aterosclerosi: ad essa conseguono eventi cardio-cerebrovascolari. I fattori di rischio cardiovascolari più coinvolti in AR sono ipertensione arteriosa (IA), dislipidemia, diabete mellito (DM). I glucocorticoidi causano iperglicemia e insulino-resistenza. La pressione arteriosa correla con l’incidenza di stroke, scompenso cardiaco (SCC) e patologie renali. La dislipidemia è complicanza di AR. Gli eventi CV considerati sono: infarto miocardio (IMA), SCC, interventi di rivascolarizzazione, fibrillazione atriale (FA) e stroke. IMA è l’evento più comune. Altra complicanza è l’insufficienza cardiaca. L'infiammazione cronica ha un ruolo nello scompenso cardiaco e in FA. FA è la principale aritmia cardiaca, l’incidenza può essere più elevata nei soggetti con AR; è causa principale di ictus, e il rischio di ictus è più alto nei pazienti AR. Scopi dello studio: stimare il tasso di eventi CV nei pazienti AR; stimare la frequenza di IA, DM, dislipidemia nei pazienti AR; valutare la relazione tra fattori di rischio cardiovascolare ed eventi CV nei pazienti AR rispetto alla popolazione generale nella popolazione lombarda. Lo studio è di tipo retrospettivo di coorte con dati estratti dalle banche dati sanitarie (AHD) della Lombardia tra il 1.01.2004 e il 31.12.2013. Per identificare i pazienti AR è stato applicato ai database regionali l'algoritmo dello studio RECord linkage on Rheumatic Diseases, selezionando 70,061 pazienti AR. Eliminati i soggetti con eventi CV tra il 1.01.2004 e il 31.12.2008. Identificati 20,965 soggetti AR e 245,933 soggetti non AR. Tra i soggetti AR, 1,880 hanno presentato almeno un evento CV. Si conferma un tasso di incidenza maggiore per IMA, SCC ed FA nei soggetti AR; l'incidenza di stroke ischemico non è differente. La prevalenza di IA e DM nei soggetti AR è maggiore rispetto i non AR (38.63% vs 34.29% /9.03%>8.52%); la prevalenza di dislipidemia è inferiore nei soggetti AR rispetto i non AR (15.11% vs 16.16%; p value <0.001): da considerare che la colesterolemia è ridotta in corso di AR ad elevata attività. La presenza di AR si associa ad un incremento del tasso di incidenza di IMA (49%), di SCC (51%), di FA (26%). Incremento sovrapponibile per SCC ed IMA si osserva per DM (61% e 53%). Si conferma l'assenza di incremento di incidenza di stroke in presenza di AR. IA è il fattore di rischio cardiovascolare che determina il maggior incremento del tasso di incidenza di FA e scompenso cardiocircolatorio, raddoppiandolo. Nella popolazione lombarda la presenza di AR rappresenta un fattore di rischio indipendente per eventi cardiovascolari.

Abstract

Rheumatoid arthritis (RA) affects 0.5-1% of general population. The number of cardiovascular (CV) events in patients affected by RA is 2-3 times higher compared to subjects not affected by RA. Atherosclerosis is the initial sign of CV affection in RA patients, followed by cardiovascular and cerebrovascular events. Main CV risk factors in RA are: arterial hypertension (HA), dyslipidemia, diabetes mellitus (DM). Glucocorticoids induce hyperglycemia and insulin resistance. HA is correlated with the incidence of stroke, heart failure, and kidney diseases. Dyslipidemia is a complication of RA. CV events are: acute myocardial infarction (AMI), heart failure (HF), revascularization interventions, atrial fibrillation (AF) and strokes. AMI is the most common event. Another complication is cardiac insufficiency. Chronic inflammation plays an important role in the development of HF and AF. AF is the principal cardiac arrhythmia in the general population, with a higher incidence in RA subjects; it is the main reason for stroke, with stroke risk being higher in RA patients. Aim of the study: estimate the rate of incidence of CV events in RA patients, estimate the frequency of HA, DM, dyslipidemia, evaluate the correlation between CV risk factors and CV events in RA patients in comparison with the general population in Lombardy. The study design is: cohort, retrospective based on data extracted from health databases (AHD) from Lombardy Region between January 1st 2004 and December 31st 2013. Patients were selected applying the algorithm from the study RECord linkage on Rheumatic Diseases, thus identifying 70,061 RA patients. Subjects affected by CV events between January 1st 2004 and December 31st 2008 were not considered. 20,965 RA subjects and 245,933 non RA subjects were identified. 1,880 subjects of RA subjects presented at least one cardiovascular event. Our analysis confirms a significantly higher incidence for AMI, HF, and AF in RA subjects; the incidence of ischemic stroke shows no difference. Prevalence of HA and DM is higher in RA subjects in comparison with not-RA subjects (38.63% vs 34.29%, p value <0.001 / 9.03%>8.52%, p value 0.012). The prevalence of dyslipidemia is lower in RA subjects than not-RA subjects (15.11% vs 16.16%, p value <0.001). It is to be considered that cholesterol levels are reduced in high activity RA. RA is associated with an increased incidence rate (p<0.001) of AMI (49%), HF (51%), AF (26%). A similar increase of HF and AMI is observed in DM (61% and 53% respectively). No increase of stroke incidence was observed in RA patients. HA is the cardiovascular risk factor determining the highest increase of incidence rate of AF and HF, doubling the rate. In Lombard population, RA represents an independent risk factor for cardiovascular events.
