Aerobic Exercise is Cardio-protective in Hemato-oncological Disease and New-onset Chemotherapy

Summary

Oncological diseases are the main cause of death in developed countries and also in Uruguay. Advances in therapeutics have made possible to aspire to cure and in other cases long-term remission with a significant increase in survival and the transformation of cancer into a chronic disease. Chemotherapy treatments have some side effects and cardiotoxicity is well known within them. Heart failure (HF) is a progressive pathology, with high mortality and high resource requirements of the health system with a prognosis that may be worse than some types of cancers. The treatment of established systolic dysfunction and symptomatic HF is mainly based on the indication of inhibitors of the angiotensin-converting enzyme and beta-blockers among other pharmaceutical and no pharmaceutical interventions. Aerobic physical exercise, as a therapeutic intervention, reverses the physiopathological changes that are presumed to lead to HF in sedentary people and it is known, it is feasible to execute an exercise program in cancer patients. However, effective treatments for the primary prevention of systolic dysfunction are not well known. Our hypothesis is that an aerobic physical exercise program for at least 3 months, in subjects with lymphoma and new-onset chemotherapy, is effective in preventing left ventricular systolic dysfunction, at the end of chemotherapy and at one year. For this, the investigators propose a randomized, controlled, clinical study which is blind both for the patient and the evaluating physician, comparing the difference of global longitudinal strain (an echocardiographic result of myocardial function) pre-chemotherapy minus end of chemotherapy and minus one year after, between the active group (aerobic program) and the control group (flexibility program).

Interventions

BEHAVIORAL

Aerobic exercise (experimental)

3 times per week, 30 minutes each time. Entrance in heat: 8-10 min of joint mobility and / or the aerobic exercise in the main part at light intensity (OMNI 3-4) Main part: minimum 30 minutes, maximun 60 minutes. Intensity: moderate, guided by Talk Test and effort perception scale 5-6 OMNI. Type: aerobic, cycling or walking at home using a treadmill or exercise bike and / or cycling and walking outdoors according to the patient's possibilities and preferences. Return to calm: 5 min of aerobic physical activity of main part at mild intensity (OMNI 3-4), then static stretching. Pictures with each type of exercise will be offered and detailed explained.

BEHAVIORAL

Flexibility exercise (active comparator)

Entrance in heat: 10 min of joint mobility. Main part: Minimum 30 minutes. Frequency: 3 times por week Intensity: The patient should be able to slowly stretch the muscle to a position of mild discomfort. Type: Static Stretch Time: 15-30 seconds 2 repetitions of each stretch Number of exercises: 12 . Pictures with each muscle group to exercise will be offered and detailed explained.
