Low-Dose Aspirin as Primary Prophylaxis for Cardiovascular Events in Rheumatoid Arthritis: An Italian Multicentre Retrospective Study

A Thorough Literature Review of the Potential Benefits and Drawbacks of Long-Term Aspirin Use for the Primary Prevention of Cardiovascular Disease

This article examines the role of aspirin in the primary prevention of cardiovascular disease. It highlights findings from major studies such as ASPREE (ASPirin in Reducing Events in the Elderly), ARRIVE (Aspirin to Reduce Risk of Initial Vascular Events), and ASPREE-XT (ASPirin in Reducing Events in the Elderly - eXTension) , among others. The review focuses on aspirin's role in primary prevention for specific populations including older adults, diabetics, hypertension patients, rheumatoid arthritis patients, kidney transplant recipients, and those with specific lipoprotein(a) genotypes, among other groups. We review these studies, noting aspirin's role in reducing events such as myocardial infarctions and its potential for increasing bleeding risks. The review also considers the implications for patients with kidney disease, referencing the Chronic Renal Insufficiency Cohort (CRIC) study and the International Polycap Study-3 (TIPS-3) trial. Additionally, it addresses the shifting paradigms in guidelines from the US Preventive Services Task Force and other entities, underscoring the importance of individualized aspirin use by balancing benefits against bleeding risks. The article further explores the concept of platelet reactivity, discusses strategies for improving adherence to aspirin therapy, and identifies existing research gaps, such as the phenomenon of aspirin resistance. It concludes by suggesting potential areas for future investigation to enhance understanding and application of aspirin in cardiovascular disease prevention.

Cardiovascular Disease in Anti-neutrophil Cytoplasm Antibody-Associated Vasculitis

PURPOSE OF REVIEW

Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a rare, multisystem, autoimmune disease characterised by microvascular inflammation. Over the past 20 years, advances in immunological management have improved short-term patient outcomes. Longer-term patient outcomes remain poor with cardiovascular disease now the leading cause of death in AAV. Here, we examine the potential pathways that contribute to the increased risk of cardiovascular disease in AAV and the current evidence to manage this risk.

RECENT FINDINGS

The incidence of cardiovascular disease in AAV exceeds that expected by traditional risk factors alone, suggesting a contribution from disease-specific factors. Similarly, it is unclear how different immunosuppressive therapies contribute to and modify cardiovascular risk, and there is a paucity of data examining the efficacy of traditional cardioprotective medications in AAV. There is a lack of evidence-based cardiovascular risk assessment tools and cardioprotective therapies in patients with AAV which should be addressed to improve long-term outcomes.

The role of aspirin in the primary prevention of accelerated atherosclerosis in systemic autoimmune rheumatic diseases

Aspirin is the most commonly used medication worldwide. Beside its well-known anti-inflammatory effects, a role has emerged in the prevention of cardiovascular events. However, a significant benefit has been demonstrated in secondary cardiovascular prevention only, while there is limited evidence supporting a role in primary prevention. This discrepancy might depend on the that so far, the high-risk populations that will achieve the greatest benefits yet experiencing minimal harmful side effects have not been identified. Patients with autoimmune systemic rheumatic diseases have an increased risk of cardiovascular complications compared with the general population, which makes aspirin of potential value in these subjects. Moving from general aspects of aspirin pharmacology and specific issues in general population, the aim of this study is to review the evidence about the role of low-dose aspirin in primary cardiovascular prevention in autoimmune systemic rheumatic diseases.

The Second Gaddum Lecture: its origins and outcomes

Fifty years ago, the BJP published the Second Gaddum Lecture, given by John Vane to the British Pharmacological Society. This article assesses the origins of the experiments described in the Lecture, linking them directly to Gaddum's use of bioassay, a defining feature of pharmacology. The outcomes of those experiments are also assessed, tracking those results that have survived the past five decades. Two of the major advances in cardiovascular medicine, the ACE inhibitors, as anti-hypertensives, and low-dose aspirin, to prevent thrombosis were initiated by the work in this Lecture. Physiologically significant outcomes include a new non-respiratory function of the lung, based on the metabolism of endogenous vasoactive substrates in the pulmonary circulation and the recognition of the endothelium as a highly interactive component of blood vessels. The present state of the art in pharmacology, physiology and medicine owes much to the work described in the Second Gaddum Lecture.

Vasodilators and low-dose acetylsalicylic acid are associated with a lower incidence of distinct primary myocardial disease manifestations in systemic sclerosis: results of the DeSScipher inception cohort study

OBJECTIVES

To investigate the influence of vasodilator drugs on the occurrence of features depending on myocardial ischaemia/fibrosis (ventricular arrhythmias, Q waves, cardiac blocks, pacemaker implantation, left ventricular ejection fraction (LVEF) <55%, and/or congestive heart failure and sudden cardiac death) in systemic sclerosis (SSc).

METHODS

601 patients with SSc were enrolled from 1 December 2012 to 30 November 2015 and had a second visit 0.5-4 years apart. 153 received no vasodilators; 448 received vasodilator therapy (ie, calcium channel blockers and/or ACE inhibitors or angiotensin II receptor blockers or combinations of them), 89 of them being also treated with either endothelin receptor antagonists or PDE5 inhibitors or prostanoids. Associations between the occurrence of myocardial disease manifestations and any demographic, disease and therapeutic aspect were investigated by Cox regression analysis. A Cox frailty survival model with centre of enrolment as random effect was performed.

RESULTS

During 914 follow-up patient-years, 12 ventricular arrhythmias, 5 Q waves, 40 cardiac blocks, 6 pacemaker implantations and 19 reduced LVEF and/or congestive heart failure (CHF) occurred. In multivariate Cox regression analysis, vasodilator therapy was associated with a lower incidence of ventricular arrhythmias (p=0.03); low-dose acetylsalicylic acid (ASA) with a lower incidence of cardiac blocks and/or Q waves and/or pacemaker implantation (p=0.02); active disease with a higher incidence of LVEF <55% and/or CHF and cardiac blocks and/or Q waves and/or pacemaker implantation (p=0.05).

CONCLUSIONS

The present study might suggest a preventative effect on the occurrence of distinct myocardial manifestations by vasodilator therapy and low-dose ASA.
