Molecular effects of cardiac contractility modulation in patients with heart failure of ischemic aetiology uncovered by transcriptome analysis.

Cardiac contractility modulation (CCM) is based on electrical stimulation of the heart without alteration of action potential and mechanical activation, the data on its fundamental molecular mechanisms are limited. Here we demonstrate clinical and physiological effect of 12 months CCM in 29 patients along with transcriptomic molecular data. Based on the CCM effect the patients were divided into two groups: responders ( = 13) and non-responders ( = 16).

Clinical Response to Personalized Exercise Therapy in Heart Failure Patients with Reduced Ejection Fraction is Accompanied by Skeletal Muscle Histological Alterations.

Heart failure (HF) is associated with skeletal muscle wasting and exercise intolerance. This study aimed to evaluate the exercise-induced clinical response and histological alterations. One hundred and forty-four HF patients were enrolled.

Skeletal Muscle Resident Progenitor Cells Coexpress Mesenchymal and Myogenic Markers and Are Not Affected by Chronic Heart Failure-Induced Dysregulations.

Background And Purpose: In heart failure (HF), metabolic alterations induce skeletal muscle wasting and decrease of exercise capacity and quality of life. The activation of skeletal muscle regeneration potential is a prospective strategy to reduce muscle wasting; therefore, the aim of this project was to determine if functional properties of skeletal muscle mesenchymal progenitor cells (SM-MPC) were affected by HF-induced functional and metabolic dysregulations.

Methods: Gastrocnemius muscle biopsy samples were obtained from 3 healthy donors (HD) and 12 HF patients to purify mRNA for further analysis and to isolate SM-MPC.

[Results of 3 years work of the Russian hospital register of chronic heart failure (RUssian hoSpital Heart Failure Registry - RUS-HFR): relationship between management and outcomes in patients with chronic heart failure].

Aim: To analyze management and outcomes in patients with CHF managed by specialists in heart failure (HF) or general cardiologists/physicians in real-life clinical practice.

Materials And Methods: Survival rate, rehospitalization rate, general health condition, and the administered therapy were evaluated for HF patients with reduced LV ejection fraction at three years of discharge from cardiological hospitals. These patients had been included in a prospective, multicenter, observational study, "The Russian Hospital HF Registry" (RUS-HFR).

[Response predictors for physical training HFrEF patients].

Purpose: To identify different types and possible predictors of physical rehabilitation (PR) response in reduced ejection fraction heart failure (HFrEF) patients, selected on the basis of achievement the lactate threshold during cardiopulmonary exercising test (CPET).

Methods: 64 patients, chronic heart failure (CHF) NYHA II-III functional class were included in our study. Mean age 54±12,5 years, body mass index (BMI) 26,5±6,4 kg/m2, ejection fraction (EF) 26,4±1,4 %, NYHA II: III (67 %: 33 % patients).
