Eligibility

Age
18 Years to 90 Years

Inclusion criteria

Inclusion criteria: Patients with ischemic cardiomyopathy with an ejection fraction of the left ventricle than or equal to 35% of both sexes. The minimum age of 18 years and maximum 90 years.

Exclusion criteria

Exclusion criteria: Functional limitations not related to the cardiovascular system. Such as disabling lung diseases and tumors of advanced degree.

Design outcomes

Primary

MeasureTime frame
Increased tolerance of exercise time during constant workload test (in minutes) and shorter duration of oxygen uptake kinetics (tau, an indirect marker of oxidative metabolism) in seconds. It is estimated, after 3 months supervised physical training an increase of at least 10% in the time in minutes (min) exercise tolerance and a reduction of at least 5% at time kinetics in seconds (s), based on previous studies using other types of intervention such as drugs or percutaneous cardiac intervention (PCI).—

Secondary

MeasureTime frame
Increase in aerobic power (a measure of maximum oxygen consumption in L/min and ml.kg.min-1, the ventilatory efficiency (ratio of minute ventilation over carbon dioxide production (VE/VCO 2) and indexes of quality of life in the various fields extracted from the SF 36 questionnaire (Short Form 36).;Increased quality of life assessed by SF 36 which shows a final score ranging from 0 to 100, where "0" is the worst overall health status and "100" the best. It is expected an increase in the score of this general health questionnaire.—
