Insights
Elevated D-dimers and prolonged PT-INR indicate higher in-hospital mortality in infective endocarditis (IE). Shorter activated partial thromboplastin time (aPTT) predicts embolic events, while longer aPTT is linked to increased 1-year mortality in IE patients.
Area of Science:
- Cardiology
- Hematology
- Infectious Diseases
Background:
- Infective endocarditis (IE) is a serious infection affecting heart valves.
- Hemostasis parameters play a crucial role in IE pathogenesis and outcomes.
- Assessing prognostic markers in IE is vital for patient management.
Purpose of the Study:
- To evaluate the clinical significance of key hemostasis markers in IE.
- To determine the prognostic role of PT-INR, aPTT, fibrinogen, D-dimers, platelet count, and homocysteine in IE.
- To identify predictors of mortality and embolic complications in IE patients.
Main Methods:
- A cohort of 337 patients diagnosed with IE was analyzed.
- Clinical, hemato-chemical, and echocardiography data were collected.
- Coagulation parameters, including D-dimers and aPTT, were measured upon admission.
Main Results:
- Elevated D-dimers and prolonged PT-INR were associated with increased in-hospital mortality (p=0.012, p=0.013).
- Prolonged aPTT correlated with higher 1-year mortality (p=0.021).
- Higher D-dimer levels and shorter aPTT were linked to embolic complications (p<0.001).
Conclusions:
- Elevated D-dimers are a significant predictor of in-hospital mortality in IE.
- Both high D-dimers and short aPTT are associated with a greater risk of embolic events in IE.
- aPTT duration serves as a prognostic indicator for both short-term and long-term outcomes in IE.
Abstract:
(1) Background: The aim of this study was to assess the clinical significance and prognostic role of the main hemostasis parameters in infective endocarditis (IE): prothrombin time as international normalized ratio (PT-INR), activated partial thromboplastin time (aPTT), fibrinogen, D-dimers, platelet count, homocysteine. (2) Methods: We studied 337 patients with IE. Clinical, hemato-chemical and echocardiography parameters were analyzed. Coagulation parameters were measured on admission. (3) Results: D-dimers levels (p = 0.012) and a prolonged PT-INR (p = 0.013) were associated with higher in-hospital mortality, while prolonged aPTT (p = 0.021) was associated with increased 1-year mortality. Staphylococcus aureus (S. aureus) infection (p = 0.003), prosthetic valve endocarditis (PVE) (p = 0.001), surgical indication (p = 0.002) and higher D-dimer levels (p = 0.005) were independent predictors of in-hospital mortality. PVE (p = 0.001), a higher Charlson Comorbidity Index (p = 0.049), surgical indication (p = 0.001) and prolonged aPTT (p = 0.012) were independent predictors of 1-year mortality. Higher levels of D-dimers (p < 0.001) and a shorter aPTT (p < 0.001) were associated with embolic complications of IE. S. aureus etiology was bound to higher D-dimers levels (p < 0.001) and a shorter aPTT (p = 0.006). (4) Conclusions: Elevated D-dimers are associated with a higher risk for in-hospital mortality in IE patients. High D-dimers and a short aPTT are associated with a higher risk for embolic events in IE. A longer aPTT is associated with 1-year mortality.
