The link between rheumatoid arthritis and increased cardiovascular risk

RA commonly affects the smaller joints in the hands and feet but can also involve larger joints and organs in severe cases.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the joints, causing pain, swelling, and stiffness. However, recent research has revealed a concerning association between RA and an increased risk of cardiovascular disease (CVD).

Arthritis is a common yet complex group of conditions that affect millions of people worldwide. It refers to the inflammation of one or more joints, resulting in pain, stiffness, and reduced mobility. With over 100 different types of arthritis identified, this health issue can impact individuals of all ages, genders, and backgrounds.

Understanding the mechanisms underlying this connection is crucial for healthcare providers and patients to effectively manage RA and mitigate the risk of cardiovascular complications.

The mechanisms behind the connection

  1. Chronic Inflammation:
    RA is characterized by systemic inflammation that not only affects the joints but also impacts blood vessels and the cardiovascular system. The constant release of inflammatory cytokines can damage blood vessel walls, promoting the development of atherosclerosis. Atherosclerosis is the buildup of plaque inside arteries, leading to reduced blood flow and an increased risk of heart attacks and strokes.
  2. Endothelial Dysfunction:
    Inflammation in RA can impair the function of the endothelium, the inner lining of blood vessels. Normally, the endothelium helps regulate blood flow and maintains vessel health. However, in RA, dysfunctional endothelial cells lose their ability to dilate and constrict blood vessels appropriately. This dysfunction further contributes to atherosclerosis and increases the likelihood of blood clot formation, posing a serious risk to cardiovascular health.
  3. Autoantibodies and Oxidative Stress:
    RA triggers an autoimmune response, leading the body to produce autoantibodies that attack healthy tissues, including blood vessel walls. This immune system activation also promotes oxidative stress, an imbalance between harmful free radicals and the body’s ability to neutralize them. Oxidative stress damages blood vessels, exacerbates inflammation, and accelerates the progression of CVD in RA patients.
  4. Lifestyle Factors:
    The increased cardiovascular risk in RA cannot be attributed solely to disease-related factors. Lifestyle choices, such as physical inactivity, smoking, and an unhealthy diet, are prevalent among some RA patients and can independently contribute to CVD. Addressing these modifiable risk factors is essential to reduce the impact of RA on cardiovascular health.

Implications and recommendations

  1. Regular Cardiovascular Screening:
    Given the higher risk of CVD in individuals with RA, regular cardiovascular screening is crucial. Healthcare providers should include assessments of blood pressure, cholesterol levels, and blood sugar during routine check-ups. Identifying cardiovascular risk factors early on allows for timely intervention and lifestyle modifications to prevent or manage CVD.
  2. Comprehensive RA Management:
    Controlling RA inflammation is vital not only for joint health but also for reducing cardiovascular risk. Rheumatologists may prescribe disease-modifying anti-rheumatic drugs (DMARDs) and biologic agents to manage inflammation effectively. Treating RA aggressively can positively impact cardiovascular outcomes by mitigating the underlying inflammatory processes.
  3. Cardiovascular Prevention Strategies:
    Patients with RA and healthcare providers should collaborate to develop personalized cardiovascular prevention strategies. This may involve adopting heart-healthy habits, such as regular exercise, quitting smoking, and following a balanced diet rich in fruits, vegetables, and whole grains. Additionally, patients may benefit from medications to manage blood pressure and cholesterol levels effectively.


The link between rheumatoid arthritis and increased cardiovascular risk underscores the importance of a multidisciplinary approach to managing this autoimmune disease.

By understanding the mechanisms connecting RA and CVD, healthcare providers can implement targeted interventions and preventive measures to safeguard patients’ cardiovascular health. Regular cardiovascular screening, comprehensive RA management, and lifestyle modifications are essential components of a holistic strategy aimed at reducing the impact of rheumatoid arthritis on the heart and blood vessels.

Through collaborative efforts and early interventions, individuals with RA can lead healthier lives, with a reduced risk of cardiovascular complications.
