Key result

Chronic intravascular coagulation, indicated by increased D-dimer, was associated with increased t-PA (p<0.0001) and vWF:Ag (p=0.001) and decreased thrombomodulin (p<0.0001) in Eisenmenger syndrome.

Population

21 patients with Eisenmenger syndrome, ages 4-52 years, categorized into stable and unstable disease.

Design

Cross-sectional

Implication

Endothelial markers may flag coagulopathy risk in Eisenmenger syndrome; hypothesis-generating and should not yet change practice.

Study Design

Type

Observational (n=21)

Structured PICO

P
Population
21 patients aged 4 to 52 years with Eisenmenger syndrome, evaluated for chronic intravascular coagulation and endothelial dysfunction.
C
Comparator
Stable disease (group 1) vs unstable disease (group 2)
O
Outcome
Association of chronic intravascular coagulation (D-dimer levels) with endothelial markers (t-PA, thrombomodulin, vWF:Ag) and clinical severitysurrogate

Main Result

p-value: p=<0.0001

In patients with Eisenmenger syndrome, endothelial dysfunction is associated with chronic intravascular coagulation and correlates with symptom severity.

Cite This Study

Lopes et al. (2002) conducted an observational in Eisenmenger syndrome (n=21). Chronic intravascular coagulation (elevated D-dimer) vs. Normal D-dimer levels was evaluated on Endothelial markers (t-PA, vWF:Ag, thrombomodulin) (p=<0.0001). Chronic intravascular coagulation, indicated by increased D-dimer, was associated with increased t-PA (p<0.0001) and vWF:Ag (p=0.001) and decreased thrombomodulin (p<0.0001) in Eisenmenger syndrome.
