Because the improvement of exercise tolerance reduces mortality in elderly patients affected by cardiovascular disease, intermittent hypoxia therapy (IHT) - defined as repeated episodes of hypoxia interspersed with normoxic periods delivered by an ad hoc device - might be a valuable tool to be associated to structured cardiac rehabilitation (CR) interventions. The present study is a pilot, monocentric, randomized (randomization ratio 1:1), parallel group study to assess the effect of IHT on functional capacity vs conventional care in old patients with functional impairment admitted to a phase 2 in-hospital cardiac rehabilitation program. The study will enroll cardiac patients of both genders, ? 75 years and with a functional impairment assessed by a Short Physical Performance Battery (SPPB) score < 7. The effect of IHT on functional capacity will be evaluated on top of the conventional multidisciplinary CR intervention, by means of SPPB score variation; variations in quality of life and cognitive status will also be evaluated as secondary goals of the study. The total amount of IHT sessions per patient will be 10, 1 per day over 2 weeks, the duration of each single procedure will be 45 min and the Hypoxic O2 conc.% will be 14-10. The study was approved by local ethic committee.
