Heart failure with preserved ejection fraction (HFpEF) is linked to a procoagulant state, indicated by elevated D-dimer, tPA, and PAI-1 levels. These markers suggest increased blood clotting activity in HFpEF patients compared to healthy individuals.
Area of Science:
- Cardiology
- Hematology
- Biochemistry
Background:
- Hemostasis activation in heart failure with preserved left ventricular ejection fraction (HFpEF) remains poorly understood.
- Previous research has not fully elucidated the impact of HFpEF on coagulation and fibrinolysis pathways.
Purpose of the Study:
- To compare hemostasis activation in patients with HFpEF, heart failure with impaired LVEF, and healthy controls.
- To investigate the relationship between LVEF status and specific coagulation/fibrinolysis biomarkers.
Main Methods:
- Biomarkers of coagulation and fibrinolysis, including D-dimer, tissue plasminogen activator (tPA), and plasminogen activator inhibitor-1 (PAI-1), were measured.
- Outpatients with chronic stable HFpEF (NYHA I-III) and heart failure with impaired LVEF, along with healthy controls, were enrolled.
Main Results:
- Patients with HFpEF exhibited significantly higher median D-dimer, PAI-1, and tPA antigen levels compared to healthy controls.
- While D-dimer levels were elevated in HFpEF, they were not as high as in patients with impaired LVEF.
- Age and NT-proBNP were independent predictors of D-dimer levels in patients with impaired LVEF, but not in those with HFpEF.
Conclusions:
- Heart failure with preserved LVEF is associated with a procoagulant state, evidenced by increased D-dimer, tPA, and PAI-1.
- Elevated tPA and PAI-1 levels are observed irrespective of LVEF status in heart failure patients.
- D-dimer levels are significantly higher in heart failure with impaired LVEF compared to HFpEF.
