Association Between Inflammation and Risk of Cardiovascular Mortality in Cancer Survivors

Area of Science:

• Cardiovascular Medicine
• Oncology
• Inflammation Research

Background:

• Cancer and cardiovascular disease (CVD) share high mortality rates and disease burden.
• Inflammation is a common risk factor for both cancer and CVD.
• Limited data exists on systemic inflammation's impact on CVD mortality in cancer survivors.

Purpose of the Study:

• To investigate the association between inflammation and cardiovascular mortality in cancer survivors.
• To determine if elevated C-reactive protein (CRP) levels predict CVD mortality in this population.

Main Methods:

• Analysis of 15,420 UK Biobank participants with a history of cancer and no active therapy.
• Utilized multivariable competing-risk models to assess CRP levels and CVD mortality risk.
• Adjusted for sociodemographic, lifestyle, and clinical factors.

Main Results:

• Elevated CRP levels (>2 mg/L) were associated with a 1.12-fold higher risk of cardiovascular death in unadjusted analyses.
• After multivariable adjustment, CRP levels >2 mg/L remained significantly linked to a 64% increased risk of cardiovascular death (sHR: 1.64; P = 0.023).
• Subgroup analyses confirmed these consistent findings.

Conclusions:

• Chronic inflammation is significantly associated with increased cardiovascular mortality in cancer survivors.
• Findings suggest a potential therapeutic target for reducing CVD mortality in cancer survivors.
• Further research is warranted to explore interventions targeting inflammatory pathways.
