Abstrakt		In the last years a number of studies have shown that there is no need for patients with hearth failure to avoid physical activity and that they benefit with regular exercise training. Patients with heart failure have decreased functional capacity because of the inability of the heart to maintain or increase cardiac output at a rate commensurate with somatic aerobic requirements. The NYHA classification of functional capacity is imprecise because of its subjective nature. Cardiopulmonary exercise testing and measurement of oxygen consumption (VO2) offer an objective evaluation of functional capacity. Cardiopulmonary exercise testing provides an important information for risk stratification within group of patients with heart failure. In the case of a heart failure, exercise test should only be performed in patient with a stable clinical condition. There are a lot of different protocols and their modifications. Which protocol will be chosen, often depends on the experience of the physician performing the test Recently published exercise testing guidelines have recommended that the exercise protocol should be individualized for each patient.
Izvleček		Obremenitvena zmogljivost je pri bolnikih s srčnim popuščanjem zmanjšana, ker srce ni sposobno vzdrževati ali povečevati minutnega volumna glede na telesne aerobne zahteve. Funkcionalna ocena teh bolnikov je po klasifikacijskem sistemu NYHA pomanjkljiva predvsem zaradi subjektivnosti. Obremenitveno testiranje z merjenjem dosežene porabe kisika (VO2) nam omogoča objektivno oceno funkcionalne zmogljivosti. Podatki, ki jih dobimo, so koristni tudi za oceno prognoze bolnikov s srčnim popuščanjem. Obremenitveno testiranje je potrebno opraviti, ko je bolnik v klinično stabilnem stanju. Obstoji vrsta različnih testov in njihovih modifikacij. Protokol, ki ga izberemo, je odvisen od izkušenj zdravnika, ki opravi preiskavo. Po zadnjih priporočilih pa naj bi bili protokoli individualizirani, tj. prilagojeni telesni zmogljivosti posameznika.
