Clinical 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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. 3 months
Secondary 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. 3 months
