Is the Calcium Score Useful for Rheumatoid Arthritis Patients at Low or Intermediate Cardiovascular Risk?

Identification of Coronary Morphological Damage in Patients with Chronic Inflammatory Rheumatic Diseases

Objective: Patients with chronic inflammatory rheumatic diseases (CIRDs) have a higher incidence of coronary artery disease (CAD) due to accelerated atherogenesis. This study aimed to assess the extent and location of CAD lesions in CIRD patients compared to non-CIRD patients. Methods: A retrospective study was conducted on CIRD patients (rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis) who underwent coronary angiography at Hospital Fundación Jiménez Díaz (Madrid, Spain) between 2018 and 2022. For each CIRD patient, at least two frequency-matched controls were selected based on sex, age (±2 years), diabetic status, and clinical indication for coronary angiography. The indications for coronary angiography in both groups were chronic coronary syndrome and acute coronary syndrome with or without ST elevation. Results: A total of 66 CIRD patients were included, with 42 (63.6%) women, and a median age of 66.6 years (range: 58.3-75.2). Compared to the controls, CIRD patients had a higher number of affected coronary arteries (2.03 vs. 1.56, p = 0.03). The mid-anterior descending artery and the right posterior descending artery were more frequently involved in CIRD patients than in controls (odds ratio [OR] of 2.45 and 3.53, respectively, p ≤ 0.02 for both comparisons). The frequency of coronary calcification was higher in CIRD patients, though the difference did not reach statistical significance (5 of 66 in CIRD patients vs. 3 of 140 in non-CIRD controls, OR of 3.74, p = 0.06). Revascularization was more commonly performed in patients with CIRD (50 of 66 vs. 85 of 140 in those without CIRD (OR: 2.02 [95% CI: 1.01-4.18]; p = 0.03). Conclusions: Patients with CIRD exhibit more extensive CAD, with a higher propensity for involvement inthe mid-anterior descending and right posterior descending arteries compared to patients without CIRD. These findings highlight the need for closer cardiovascular monitoring and early risk stratification in CIRD patients to improve the detection and management of CAD.

Causes of Mortality in Intensive Care Units for Patients with Chronic Inflammatory Diseases from the French National Health Data System

Background/Objectives: Inflammatory pathologies are at the center of various medical specialties and benefit from conventional treatments as well as biological treatments. These latter ones have often been the subject of studies yielding heterogeneous results regarding their infectious and mortality risks. This work aims to describe mortality and its causes in patients afflicted by inflammatory pathologies, receiving either conventional or biological therapy during their first stay in intensive care units. Methods: Our study was conducted using the French national health database, encompassing all hospital stays on a national scale. All comparisons between conventional treatment and biological therapies were performed using the Chi-square test, Fisher's exact test, or Student's t-test. Results: In total, 13,816 patients were included. Within 90 days of the first admission to the intensive care/reanimation service, 11.6% of the patients died, including 9.4% within 30 days and 7.3% during hospitalization. More patients died in the conventional treatment group in comparison to the biological treatment group. More deaths were observed due to cardiovascular (27%), infectious (15%), gastroenterological (12%), and oncological (12%) conditions in the conventional treatment group. However, there were as many deaths from oncological causes (19%) as from cardiovascular causes (19%) in the biological therapy group. Hypertension (66.8%) and renal insufficiency (50.4%) were the most frequently associated comorbidities with mortality. Conclusions: Mortality in intensive care/reanimation during the initial stay of patients afflicted by inflammatory pathologies is of greater concern for those treated with conventional treatments. Causes of death tend to be more cardiovascular and require more prevention and care management.

Coronary Artery Calcification in Rheumatoid Arthritis Patients: A Systematic Review

Rheumatoid arthritis (RA) is one of the leading autoimmune causes of inflammatory arthropathy worldwide. The musculoskeletal impacts of RA are well described within the literature. More recently, research efforts have highlighted that inflammation associated with the condition is not solely isolated to the joint synovium. Specifically, data has demonstrated that the cardiovascular system is negatively impacted by inflammation tied to RA, with adverse cardiovascular outcomes considered the leading cause of mortality among patients with RA. One approach to determine the risk for cardiovascular disease (CVD) is computed tomography (CT) coronary angiography, a noninvasive imaging approach that analyzes the calcifications within the coronary vessels. This has increasingly been utilized to analyze plaque burden and vessel obstruction, which is measured using the coronary artery calcium (CAC) score. A total of 305 articles were analyzed, and 11 articles were selected for this review based on inclusion and exclusion criteria. The results indicated that nearly 60% of patients with RA experienced an elevated CAC score. As such, patients with RA likely carry a higher risk for adverse cardiovascular outcomes as compared to their healthy counterparts. Additional research is warranted based on these findings to determine whether the addition of CT coronary angiography and analysis of laboratory markers for CVD, including lipid markers in standard protocols for RA comorbid assessment, would help to reduce adverse cardiovascular complications.

Use of coronarycomputed tomography for cardiovascular risk assessment in immune-mediated inflammatory diseases

Immune-mediated inflammatory diseases (IMIDs) are recognised risk factors for accelerated atherosclerotic cardiovascular disease (CVD), particularly in younger individuals and women who lack traditional CVD risk factors. Reflective of the critical role that inflammation plays in the formation, progression and rupture of atherosclerotic plaques, research into immune mechanisms of CVD has led to the identification of a range of therapeutic targets that are the subject of ongoing clinical trials. Several key inflammatory pathways implicated in the pathogenesis of atherosclerosis are targeted in people with IMIDs. However, cardiovascular risk continues to be systematically underestimated by conventional risk assessment tools in the IMID population, resulting in considerable excess CVD burden and mortality. Hence, there is a pressing need to improve methods for CVD risk-stratification among patients with IMIDs, to better guide the use of statins and other prognostic interventions. CT coronary angiography (CTCA) is the current first-line investigation for diagnosing and assessing the severity of coronary atherosclerosis in many individuals with suspected angina. Whether CTCA is also useful in the general population for reclassifying asymptomatic individuals and improving long-term prognosis remains unknown. However, in the context of IMIDs, it is conceivable that the information provided by CTCA, including state-of-the-art assessments of coronary plaque, could be an important clinical adjunct in this high-risk patient population. This narrative review discusses the current literature about the use of coronary CT for CVD risk-stratification in three of the most common IMIDs including rheumatoid arthritis, psoriasis and systemic lupus erythematosus.

Prevalence of cardiovascular diseases and traditional cardiovascular risk factors in patients with rheumatoid arthritis: a real-life evidence from BioSTAR nationwide registry

Patients with rheumatoid arthritis (RA) have increased morbidity and mortality due to cardiovascular (CV) comorbidities. The association of CV diseases (CVD) and traditional CV risk factors has been debated, depending on patient and RA characteristics. This study aimed to find the prevalence of CVD and CV risk factors in patients with RA. A multi-center cross-sectional study was performed on RA patients using the BioSTAR (Biological and Targeted Synthetic Disease-Modifying Antirheumatic Drugs Registry) in September 2022. Socio-demographic, clinical, and follow-up data were collected. Myocardial infarction, ischemic heart disease, peripheral vascular disorders, congestive heart failure, ischemic stroke, and transient ischemic attack were regarded as major adverse cardiovascular events (MACEs). CVD was defined as the presence of at least one clinical situation of MACE. Group 1 and Group 2 included patients with and without CVD. Prevalence rates of CVD and traditional CV risk factors were the primary outcomes. Secondary outcomes were the differences in the clinical characteristics between patients with and without CVD. An analysis of 724 patients with a mean age of 55.1 ± 12.8 years diagnosed with RA was conducted. There was a female preponderance (79.6%). The prevalence rate of CVD was 4.6% (n = 33). The frequencies of the diseases in the MACE category were ischemic heart disease in 27, congestive heart failure in five, peripheral vascular disorders in three, and cerebrovascular events in three patients. The patients with CVD (Group 1) were significantly male, older, and had higher BMI (p = 0.027, p < 0.001, and p = 0.041). Obesity (33.4%) and hypertension (27.2%) were the two CV risk factors most frequently. Male sex (HR = 7.818, 95% CI 3.030-20.173, p < 0.001) and hypertension (HR = 4.570, 95% CI 1.567-13.328, p = 0.005) were the independent risk factors for CVD. The prevalence of CVD in RA patients was 4.6%. Some common risk factors for CVD in the general population, including male sex, older age, and hypertension, were evident in RA patients. Male sex and hypertension were the independent risk factors for developing CVD in patients with RA.
