Background: Physical inactivity is an important risk factor for cardiovascular disease. The benefits of exercise in patients with chronic diseases, including cardiovascular diseases, are well established. For patients with sickle cell disease, medical recommendation was to avoid physical exercise for fear of triggering painful crises or increasing the impairment of the cardiopulmonary function. Only recently, studies have shown safety in exercise programs for this population. Despite that, there is no report that assess the effects of physical exercise on cardiac parameters in patients with sickle cell disease.

Objective: This study aimed to evaluate the impact of regular physical exercise (a home-based program) on cardiovascular function in patients with sickle cell disease.

Design: A quasi-randomized prospective controlled trial.

Setting: During the years 2015 and 2016, we started recruiting among adult patients treated at a Brazilian Center for Patients with Sickle Cell Disease to participate in a study involving a home exercise program. The experimental (exercise) and control groups were submitted to clinical evaluation and cardiovascular tests before and after the intervention. Analysis of variance was applied to compare groups, considering time and group factors.

Participants: Twenty-seven adult outpatients with a sickle cell disease diagnosis.

Interventions: Exercise group (N = 14): a regular home-based aerobic exercise program, three to five times per week not exceeding give times per week, for eight weeks; no prescription for the control group (N = 13).

Main Outcome Measures: Echocardiographic and treadmill test parameters.

Results: The exercise group showed significant improvement in cardiovascular tests, demonstrated by increased distance traveled on a treadmill (p<0.01), increased ejection fraction (p < 0.01) and improvement of diastolic function assessed by mitral tissue Doppler E' wave on echocardiography (p = 0.04). None of the patients presented a sickle cell crisis or worsening of symptoms during the exercise program.

Conclusion: The selected home-based exercise program is safe, feasible, and promotes a favorable impact on functional capacity and cardiovascular function in sickle cell disease patients.

Influence of an exercise program on cardiac remodeling and functional capacity in patients with stroke (CRONuS trial): study protocol for a randomized controlled trial.

Trials 2019 May 28;20(1):298. Epub 2019 May 28.

Department of Internal Medicine, Botucatu Medical School (UNESP), São Paulo State University, District of Rubião Junior, Botucatu, SP, 18618-687, Brazil.

Background: Cardiovascular rehabilitation is one of the treatment options for post-stroke individuals in order to improve functional independence in activities of daily life and reduce energy expenditure. The aim of this trial is to evaluate the effect of an exercise program on the echocardiographic variables, functional capacity, inflammatory response, neurological status, nutritional status, cardiologic evaluation, and quality of life of patients after stroke.

Methods/design: This is a randomized controlled trial including patients with ischemic stroke in the chronic phase. The patients will be evaluated at the beginning of the study and after 16 weeks. This will include clinical and physical evaluation, 6-min walk test, neurological assessment, nutritional assessment, ambulatory blood pressure monitoring, transthoracic echocardiography, and assessment of the quality of life. The sample size has been determined as 40 patients, who will be divided into two groups: control group (CG; n = 20) and intervention group (IG; n = 20). The CG will undergo conventional physiotherapy for 45 min, three times a week, up to 16 weeks, while the IG will be put on a cardiovascular rehabilitation program consisting of heating, aerobic exercise, and muscle strengthening for 45 min, three times a week, for 16 weeks. The primary endpoint will be functional capacity following a 6-min walk test (delta maxVO) and morphofunctional echocardiographic variables (indexed left ventricular mass) before and after the intervention.

Discussion: We expect to observe an improvement in cardiac structural and functional abnormalities in the IG, on echocardiography and biochemical examination, and that the improvement of these parameters after cardiovascular rehabilitation will have a favorable impact on the functional capacity and quality of life of patients after stroke.
