Functional iron deficiency and diastolic function in heart failure with preserved ejection fraction.
Functional iron deficiency (FID) is an independent risk factor for poor outcome in advanced heart failure with reduced EF, but its role in heart failure with preserved EF (HFPEF) remains unclear. We aimed to investigate the impact of FID on cardiac performance determined by pressure-volume loop analysis in HFPEF. ⋯ In non-anemic HFPEF patients, cardiac dysfunction and impaired exercise capacity occur independently of FID.

Multicenter Study
Rheumatoid arthritis and risk of acute myocardial infarction--a nationwide retrospective cohort study.
Rheumatoid arthritis (RA) imposes substantial social costs, including an increased risk of work-related disability and accelerated cardiovascular diseases. The aim of the study is to determine the risk of acute myocardial infarction (AMI) associated with RA in a nationwide retrospective cohort study. ⋯ This nationwide retrospective cohort study indicates that AMI risk increased by 38% in RA patients compared to the general population. Comorbidities increase the AMI risk independently.
