Endtidal Carbon Dioxide for Earlier Detection of Pulmonary Hypertension (EARLIER)

May 18, 2022 updated by: Sophie Herbst, University of Giessen

Endtidal Carbon Dioxide for Earlier Detection of Pulmonary Hypertension in Patients With Suspicion of Pulmonary Hypertension

Measurement of the endtidal carbon dioxide by capnography to exclude or to ensure the diagnosis pulmonary hypertension. The aim of the study is to obtain an endtidal carbon dioxide cut-off value for the diagnostic algorithm for pulmonary hypertension as an easily measurable and cheap diagnostic tool in patients with suspicion of pulmonary hypertension.

Study Overview

Detailed Description

The disease pulmonary hypertension is due to a remodeling of the lung vessels which results in a change of the exhaled air. This change is measurable with a so called capnograph. The investigators want to measure the breath from patients with and without pulmonary hypertension to detect a cut-off value for the diagnosis pulmonary hypertension.

Patients which have the probably diagnosis pulmonary hypertension and are older than 18 years are investigated. This patients will get an right heart catheterization and a measurement from their exhaled air.

Design Details

  • Observational Models: Cohort
  • Time Perspectives: Prospective

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Suspicion of pulmonary hypertension
At Patients with suspicion of pulmonary hypertension, which get a right heart catheterization, in the context of the study the exhaled air, precious the endtidal carbon dioxide (CO2), before or after the right heart catheterization will be measured through capnography.
Measuring of the exhaled air, especially endtidal co2, through capnography.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measurement PetCO2
Time Frame: At baseline
Measurement PetCO2 by capnography at rest after or before a right heart catheterization, comparison of the parameter between patients with and without
At baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Establishing a cut-off
Time Frame: At baseline
Establishing a cut-off for the non-invasive diagnosing of pulmonary hypertension, which differs between patients with and without pulmonary hypertension and save patients without the disease before a dispensable invasive right heart catheterization
At baseline
