Trial summary

The aim of the present study was to evaluate if the analysis of NT-proBNP might be used as an initial step for the diagnosis of chronic heart failure in patients with COPD in primary health care, and to select patients for a further examination by echocardiography. Read more about this study

About this study

Official title: Using NT-proBNP to Detect Chronic Heart Failure in Patients With Chronic Obstructive Pulmonary Disease.

The aim of the present study was to evaluate if the analysis of NT-proBNP might be used as an initial step for the diagnosis of chronic heart failure in patients with COPD in primary health care, and to select patients for a further examination by echocardiography.

Read the detailed description

Patients with a confirmed diagnosis of COPD were examined regarding chronic heart failure.

  1. An interview regarding symptoms: breathlessness, orthopnoea, night cough, nocturia, walking distance.
  2. Physical examination: weight and height, heart and lung auscultation, blood pressure measurement after 5 minutes' rest in the sitting position and the presence of peripheral oedema.
  3. Electrocardiography.
  4. Natriuretic peptide- NT-proBNP (Immulite 2500, Siemens Healthcare Diagnostics AB Sweden).
  5. Patients with the NT-proBNP level of > 1200 pg/ml were referred for echocardiography to assess left ventricular function.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01801722
Study groupRoleWhat they receive
NT-proBNP,ejection fraction ,COPD stage.The group comprised 25 women (47%) and 28 men (53%). The mean age was 75.4 years (SD 7.9), 76.3 (SD 7.6) for men and 74.4 (SD 8.2) for women.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of patients with elevated NT-proBNP.

    NT-proBNP has taken only once in each patient without follow up follow up. Three months was a period when we collected data from all participants.

    Measured: 3 months

Secondary outcomes (1)
  1. Percentage of patients with abnormal left ventricular function assessed by echocardiography. Association between elevated NT-proBNP and symptoms, signs and electrocardiography.

    Echocardiography was performed once in each referred patient. Three months was a period of data collection.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease and Chronic Heart Failure, run by Lund University at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients with elevated NT-proBNP. (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2018.
