Summary

High C-reactive protein (CRP) levels in idiopathic dilated cardiomyopathy (DCM) patients indicate a poor prognosis. Measuring CRP can help identify high-risk individuals needing targeted treatment strategies for better outcomes.

Area of Science:

  • Cardiology
  • Biomarkers
  • Inflammation Research

Background:

  • Idiopathic dilated cardiomyopathy (DCM) carries a poor prognosis with variable clinical presentations.
  • Predicting individual patient outcomes in DCM is challenging using traditional laboratory data.
  • Persistent myocardial inflammation may contribute to poor outcomes in some DCM patients.

Purpose of the Study:

  • To investigate the association between plasma C-reactive protein (CRP) concentrations and patient outcomes in idiopathic DCM.
  • To determine if CRP levels can serve as a valuable biomarker for risk stratification in DCM patients.

Main Methods:

  • Plasma CRP concentrations were measured in 188 patients with idiopathic DCM over a 5-8 year follow-up period.
  • Patients were categorized into two groups: early mortality (within 5 years) and long-term survivors (≥5 years).

  • CRP levels were compared between the early mortality and long-term survivor groups.

    • Main Results:

    • Patients who died within 5 years exhibited significantly higher CRP concentrations compared to long-term survivors (1.05 ± 1.37 vs. 0.49 ± 1.04 mg/dL, p < 0.05).
    • A CRP level greater than 1.0 mg/dL was associated with a 62% mortality rate within 5 years.
    • CRP measurement demonstrated value in identifying high-risk DCM patients.

    Conclusions:

    • Elevated plasma CRP levels are significantly associated with poor prognosis and early mortality in patients with idiopathic DCM.
    • Routine CRP measurement, alongside other clinical assessments, is a valuable tool for identifying high-risk DCM patients.
    • Identifying high-risk patients through CRP levels can guide the implementation of specialized treatment strategies to improve outcomes.
