Non-invasive Assessment of Pulmonary Vascular Resistance in Elderly Patients With Chronic Obstructive Pulmonary Disease (PVR-COPD)

February 6, 2015 updated by: Vincenzo Malafarina, MD MSc, Hospital Viamed Valvanera, Spain

Observational Study of Comparison of Echocardiographic Markers of Right Ventricular Function and Electrocardiographic Signs of Chronic Cor Pulmonale in Elderly Patient With COPD

Many studies have evaluated the viability of measuring the pulmonary vascular resistance (PVR) by non-invasive methods in patients with pulmonary hypertension, pulmonary thromboembolism, ischemic cardiopathy and valvular disease. The investigators have not found other studies which evaluate the PVR in elderly patients with COPD. The hypothesis is that in patients with COPD, the severity of obstruction, expressed by GOLD class, is associated with an increase of PVR.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
right ventricular function and GOLD stages
Time Frame: cross sectional
To compare right ventricular function, evaluated by a non-invasive method such as echocardiography, with the GOLD stages in chronic obstructive pulmonary disease (COPD) patients.
cross sectional

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Right ventricular function and FEV1.
Time Frame: cross sectional
Compare right ventricular function, evaluated by a non-invasive method such as echocardiography, tricuspid annulus plane systolic excursion (TAPSE),pulmonary artery systolic pressure (PAPs) and fractional area change (FAC), with the GOLD stages in chronic obstructive pulmonary disease (COPD) patients.
cross sectional
ECG and echocardiography parameters of cor pulmonale
Time Frame: cross sectional
The correlation between right ventricular function and the electrocardiographic parameters of cor pulmonale.
cross sectional
Right ventricle function and 6M-WT.
Time Frame: cross sectional
Evaluate the correlation between the hemodynamic indices of right ventricle and the six minute walking test (6M-WT).
cross sectional
