Key result

Higher serum tPAI-1 levels were independently associated with pulmonary arterial hypertension severity, with an odds ratio of 1.02.

Why the study?

Markers other than mPAP for classifying PAH severity are not elucidated, and the relationship between serum tPAI-1, TM, and pulmonary circulation remains undetermined.

Population

100 consecutive patients with cardiac diseases undergoing right heart catheterization

Comparison

Serum coagulation and fibrinolytic marker levels across mPAP levels

Design

Retrospective study

Overview

tPAI-1 and TM were associated with PAH severity; hypothesis-generating for noninvasive biomarkers, requiring prospective confirmation.

Study Design

Type

Observational (n=100)

Multicenter

No

Structured PICO

P
Population
100 patients (mean age 68.9 years, 62% female) with cardiac diseases undergoing right heart catheterization, evaluated for the relationship between fibrinolytic markers and pulmonary artery pressure.
O
Outcome
Correlation between mean pulmonary artery pressure (mPAP) and serum fibrinolytic markers (tPAI-1 and TM)surrogate

Main Result

Odds Ratio: 1.02 (95% CI 1–1.036)

p-value: p=0.034

Serum tPAI-1 and thrombomodulin levels correlate with mean pulmonary artery pressure and may serve as non-invasive predictors of severity in early-stage pulmonary arterial hypertension.

Limitations

  • Retrospective study design
  • Small population size from heterogeneous backgrounds
  • Serum was used instead of plasma, which may overestimate tPAI-1 levels due to platelet releasate
  • retrospective nature
  • small population size
  • heterogeneous backgrounds
  • use of serum instead of plasma may overestimate tPAI-1

Cite This Study

Shoji et al. (2021) conducted an observational in Pulmonary arterial hypertension (n=100). Serum tPAI-1 levels vs. Lower tPAI-1 levels was evaluated on Independent characteristic marker of PAH severity (mPAP ≥25 mmHg) (OR 1.02, 95% CI 1.000-1.036, p=0.034). Higher serum tPAI-1 levels were independently associated with pulmonary arterial hypertension severity, with an odds ratio of 1.02.
