Randomized Controlled Trial Comparative Study
Randomized Comparison of Exercise Intervention Versus Usual Care in Older Adult Patients with Frailty After Acute Myocardial Infarction.
Older adult patients with frailty are rarely involved in rehabilitation programs after myocardial infarction. Our aim was to investigate the benefits of exercise intervention in these patients. ⋯ Mean age was 80 years (range = 70-96). In the intervention group, 44 (60%) out of 73 patients participated in the program and 23 (32%) completed it. Overall, there was a decrease in the Fried score in the intervention group at 3 months, with no effect at 1 year. However, in the intention-to-treat analysis, such change did not achieve statistical significance (P = 0.110). Only treatment comparisons made among the subgroups that participated in (P = 0.033) and completed (P = 0.018) the program achieved statistical significance. There were no differences in clinical events. Worse Fried score trajectory along follow-up increased mortality risk (hazard ratio [HR] = 2.38, 95% confidence interval [CI] 1.24-4.55, P = 0.009) CONCLUSIONS: Recruitment and retention for a physical program in older adult patients with frailty after myocardial infarction was challenging. Frailty status improved in the subgroup that participated in the program, although this benefit was attenuated after shifting to a home-based program. A better frailty trajectory might influence midterm prognosis. (ClinicalTrials.govNCT02715453).

Randomized Controlled Trial
Systemic Inflammation, Vascular Function and Endothelial Progenitor Cells after an Exercise Training Intervention in COPD.
Exercise training is a cornerstone of the treatment of chronic obstructive pulmonary disease (COPD) in all disease stages. Data about the training effects with supplemental oxygen in nonhypoxemic patients remains inconclusive. In this study we set out to investigate the training and oxygen effects on inflammatory markers, vascular function, and endothelial progenitor cells in this population of increased cardiovascular risk. ⋯ This is the first randomized controlled trial in patients with COPD to show beneficial effects of exercise training not only on exercise capacity, but also on systemic/eosinophilic inflammation and endothelial dysfunction.
