RA Tied to Higher Risk for Specific Heart Failure Type

TOPLINE:

Patients with rheumatoid arthritis (RA) face a higher risk for heart failure (HF) than those without the condition, with the elevated risk primarily driven by HF with preserved ejection fraction (HFpEF).

METHODOLOGY:

• The researchers conducted a retrospective cohort study using data from the Mass General Brigham Biobank to investigate the risk for overall HF and its subtypes, particularly HF with reduced EF (HFrEF) and HFpEF, in patients with RA.
• They included 1445 patients newly diagnosed with RA (mean age, 51.4 years; 78.7% women) and 4335 matched comparators without RA.
• Patients with RA were identified using diagnosis codes and RA-related natural language processing concepts.
• HFpEF and HFrEF were defined as HF with an EF ≥ 50% and ≤ 40%, respectively; incidences for overall HF, HFpEF, and HFrEF were calculated per 1000 person-years.

TAKEAWAY:

• The study identified 92 incident HF cases in the RA cohort and 157 in the non-RA cohort over a median follow-up of 10.3 years per patient.
• HFpEF was the predominant HF subtype in both cohorts, with a higher incidence in patients with RA than in those without the condition (4.33 vs 2.11 per 1000 person-years).
• Patients with RA showed a 79% higher risk for HF than those without the condition (adjusted hazard ratio [aHR], 1.79; 95% CI, 1.38-2.32).
• Among the HF subtypes, patients with RA had a significantly increased risk for HFpEF (aHR, 1.99; 95% CI, 1.43-2.77) but not for HFrEF.

IN PRACTICE:

“RA can be considered a human model for inflammation, and findings from this study support the notion that chronic inflammation increases risk for HFpEF,” the authors wrote.

LIMITATIONS:

This study was conducted within an academic tertiary hospital system and involved participants from a biobank, which may have introduced selection bias and limited generalizability. The study did not account for post-baseline variables that could mediate the observed associations, such as the chronic use of nonsteroidal anti-inflammatory drugs, steroids, or specific disease-modifying antirheumatic drugs. The study relied on the availability of clinically performed cardiology studies for HF subtyping, possibly introducing misclassification of HF.
