Using NT-proBNP to Detect Chronic Heart Failure in Patients With Chronic Obstructive Pulmonary Disease (NT-proBNP)

March 6, 2018 updated by: Elzbieta Kaszuba, Lund University

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.

Study Overview

Status

Completed

Conditions

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.

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 the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of patients with elevated NT-proBNP.
Time Frame: 3 months
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.
3 months

Secondary Outcome Measures

Outcome Measure
Measure Description

Percentage of patients with abnormal left ventricular function assessed by echocardiography. Association between elevated NT-proBNP and symptoms, signs and electrocardiography.
Time Frame: 3 months
Echocardiography was performed once in each referred patient. Three months was a period of data collection.
