Abstract
The effects of exercise training (ET) on the heart of aortic stenosis (AS) rats are controversial and the mechanisms involved in alterations induced by ET have been poorly clarified. In this study, we analyzed the myocardial proteome to identify proteins modulated by moderate-intensity aerobic ET in rats with chronic supravalvular AS. Wistar rats were divided into four groups: sedentary control (C-Sed), exercised control (C-Ex), sedentary aortic stenosis (AS-Sed), and exercised AS (AS-Ex). ET consisted of five treadmill running sessions per week for 16 weeks. Statistical analysis was performed by ANOVA or Kruskal-Wallis and Goodman tests. Results were discussed at a significance level of 5%. At the end of the experiment, AS-Ex rats had higher functional capacity, lower blood lactate concentration, and better cardiac structural and left ventricular (LV) functional parameters than the AS-Sed. Myocardial proteome analysis showed that AS-Sed had higher relative protein abundance related to the glycolytic pathway, oxidative stress, and inflammation, and lower relative protein abundance related to beta-oxidation than C-Sed. AS-Ex had higher abundance of one protein related to mitochondrial biogenesis and lower relative protein abundance associated with oxidative stress and inflammation than AS-Sed. Proteomic data were validated for proteins related to lipid and glycolytic metabolism. Chronic pressure overload changes the abundance of myocardial proteins that are mainly involved in lipid and glycolytic energy metabolism in rats. Moderate-intensity aerobic training attenuates changes in proteins related to oxidative stress and inflammation and increases the COX4I1 protein, related to mitochondrial biogenesis. Protein changes are combined with improved functional capacity, cardiac remodeling, and LV function in AS rats.

Abstract
Exercise capacity and quality of life (QOL) are important outcome predictors in
patients with systolic heart failure (HF), independent of left ventricular (LV)
ejection fraction (LVEF). LV diastolic function has been shown to be a better
predictor of aerobic exercise capacity in patients with systolic dysfunction and
a New York Heart Association (NYHA) classification ≥II. We hypothesized that the
currently used index of diastolic function E/e' is associated with exercise
capacity and QOL, even in optimally treated HF patients with reduced LVEF. This
prospective study included 44 consecutive patients aged 55±11 years (27 men and
17 women), with LVEF<0.50 and NYHA functional class I-III, receiving optimal
pharmacological treatment and in a stable clinical condition, as shown by the
absence of dyspnea exacerbation for at least 3 months. All patients had
conventional transthoracic echocardiography and answered the Minnesota Living
with HF Questionnaire, followed by the 6-min walk test (6MWT). In a
multivariable model with 6MWT as the dependent variable, age and E/e' explained
27% of the walked distance in 6MWT (P=0.002; multivariate regression analysis).
No association was found between walk distance and LVEF or mitral annulus
systolic velocity. Only normalized left atrium volume, a sensitive index of
diastolic function, was associated with decreased QOL. Despite the small number
of patients included, this study offers evidence that diastolic function is
associated with physical capacity and QOL and should be considered along with
ejection fraction in patients with compensated systolic HF.
