Insights

Patients with seropositive rheumatoid arthritis (RA) have a significantly increased risk of developing congestive heart failure (CHF). This longitudinal study highlights the importance of monitoring cardiovascular health in RA patients.

Area of Science:

  • Rheumatology
  • Cardiology
  • Epidemiology

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease.
  • Cardiovascular complications, including congestive heart failure (CHF), are a concern in RA patients.
  • The specific risk of CHF in seropositive RA populations requires further investigation.

Purpose of the Study:

  • To determine the association between seropositive rheumatoid arthritis (RA) and the risk of congestive heart failure (CHF).
  • To analyze the 12-year incidence of CHF in a nationwide Korean cohort with seropositive RA.

Main Methods:

  • A longitudinal cohort study using National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) data (2002-2015).
  • Defined seropositive RA by prescription of disease-modifying anti-rheumatic drugs (DMARDs) and ICD code M05.
  • Compared 2765 seropositive RA patients with 13,825 controls using Kaplan-Meier and Cox proportional hazards regression.

Main Results:

  • The adjusted hazard ratio for CHF in the seropositive RA group was 2.50 (95% CI: 1.45-4.30).
  • Increased CHF incidence rates were observed in seropositive RA females across different age groups, particularly in those without hypertension, diabetes, or dyslipidemia.
  • The risk of CHF was significantly elevated in the seropositive RA cohort.

Conclusions:

  • Seropositive rheumatoid arthritis is associated with a substantially increased risk of congestive heart failure.
  • These findings underscore the need for proactive cardiovascular risk assessment and management in patients with seropositive RA.
  • Further research may explore the underlying mechanisms linking RA and CHF.

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Heart Failure Drugs: β-Blockers01:22

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
