Abstract

Spiroergometry, cardiopulmonary exercise testing (CPX), is widely used in functional assessment of patients with both systolic and diastolic heart failure (HF). It is useful in risk stratification, gauging disease severity and also patient’s response to treatment and applied interventions in that group of patients. It enables the assessment of physiological response to exertion and identification of abnormalities that normally are not present at rest. Main parameters measuredon CPX that have prognostic value in patients with HF are: peak oxygen consumption (VO2peak), minute ventilation to carbon dioxide release ratio (VE/VCO2slope), respiratory exchange ratio (RER), end-tidal partial pressure of carbon dioxide (PETCO2), and presence of oscillatory pattern of ventilation during exercise (EOV). Cardiopulmonary exercise testing is the most objective method of functional capacity assessment. Giving so much valuable information, it seems to be the key examination in evaluation of heart failure degree and progression, and may help physicians in making up therapeutic decisions like qualification to heart transplantation (HTX). It also facilitates planning of physical exertion and rehabilitation in that group of patients.
