Iron deficiency in primary care patients with heart failure: a cross-sectional study of the heart failure in Southern Sweden (HISS) cohort
To determine the prevalence of iron deficiency among patients with heart failure in a Swedish cohort of primary care patients and to compare the severity of heart failure symptoms (NYHA class) between patients with and without iron deficiency.
Approach:
Study Design: The study utilized data from the Heart Failure in Southern Sweden (HISS) project, a prospective intervention study conducted in primary care.
Participants: Adult patients (≥ 18 years) with a diagnosis of heart failure were recruited from 20 primary health care centres in southern Sweden.
Data Collection: Data on echocardiographic findings, NYHA class, and laboratory measurements were collected from electronic medical records and blood samples.
Key Findings:
Approximately 40% of heart failure patients have iron deficiency.
Iron deficiency prevalence increases with worsening NYHA class.
Functional iron deficiency is common, often masked by elevated ferritin levels due to inflammation.
Interpretation:
The study highlights a significant prevalence of iron deficiency in primary care heart failure patients, suggesting a need for improved identification and management.
Limitations:
The study was conducted in a specific region of Sweden, which may limit generalizability.
Data collection relied on routine clinical assessments without central adjudication.
Conclusion:
Identifying and treating iron deficiency in primary care-managed heart failure patients could potentially improve symptoms and reduce hospitalizations.
National survey findings suggest many US adults report making health decisions based on social media despite widespread concerns about the accuracy of health information shared to the platforms.
