Acute and chronic effects of inspiratory muscle training in patients with type 2 diabetes mellitus: a systematic review of randomized controlled trials.

Objectives: To conduct a systematic review to determine the acute and chronic effects of inspiratory muscle training (IMT) in type 2 diabetes mellitus (T2DM) patients on cardiac autonomic function, glucose variability, inspiratory muscle strength and endurance, hemodynamic variables, and exercise capacity.

Methods: A search was carried out according to a specific search strategy, following the PRISMA statement, and three independent reviewers have undertaken the article selection process. Searches were carried out in June 2023, on the following electronic databases: EMBASE, MEDLINE (PubMed), SCOPUS (Elsevier), and Web of Science.

Effects of Respiratory Muscle Training Pre- and Post-Cardiac Surgery in Adults: A Scoping Review.

Background: Coronary artery bypass grafts (CABGs) and cardiac valve replacement surgeries (CVRSs) are common lifesaving cardiac surgeries. They are linked to an increased risk of postoperative pulmonary complications (PPCs). This review scopes the effects of inspiratory muscle training (IMT) on adult patients, considering mainly exercise capacity, lung function, and the occurrence of PPCs.

Moderate continuous or high intensity interval exercise in heart failure with reduced ejection fraction: Differences between ischemic and non-ischemic etiology.

Background: Exercise for heart failure (HF) with reduced ejection fraction (HFrEF) is recommended by guidelines, but exercise mode and intensities are not differentiated between HF etiologies. We, therefore, investigated the effect of moderate or high intensity exercise on left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) and maximal exercise capacity (peak VO) in patients with ischemic cardiomyopathy (ICM) and non-ischemic cardiomyopathy (NICM).

Methods: The Study of Myocardial Recovery after Exercise Training in Heart Failure (SMARTEX-HF) consecutively enrolled 231 patients with HFrEF (LVEF ≤ 35 %, NYHA II-III) in a 12-weeks supervised exercise program.

[Care pathway for Covid-19 patients in a hospital in Luxembourg].

The current care pathway for COVID-19 patients was set up at the Centre Hospitalier de Luxembourg following the experiences of the first wave. The role of the nurse in this pathway is fundamental: she coordinates care and the multidisciplinary team as well as the families, in addition to monitoring and treating the patients. Her tool is clinical reasoning, which is the guarantee of care adapted to the needs and expectations of the patients.

Exercise training and high-sensitivity cardiac troponin T in patients with heart failure with reduced ejection fraction.

Aims: Whether an exercise training intervention is associated with reduction in long-term high-sensitivity cardiac troponin T (hs-cTnT) concentration (a biomarker of subclinical myocardial injury) in patients with heart failure with reduced ejection fraction (HFrEF) is unknown. The aims were to determine (i) the effect of a 12 week endurance exercise training intervention with different training intensities on hs-cTnT in stable patients with HFrEF (left ventricular ejection fraction ≤ 35%) and (ii) associations between hs-cTnT and peak oxygen uptake (VO ).

Methods And Results: In this sub-study of the SMARTEX-HF trial originally including 261 patients from nine European centres, 213 eligible patients were included after withdrawals and appropriate exclusions [19% women, mean age 61.

Baseline and Exercise Predictors of V˙O2peak in Systolic Heart Failure Patients: Results from SMARTEX-HF.

Purpose: This study aimed to investigate baseline, exercise testing, and exercise training-mediated predictors of change in peak oxygen uptake (V˙O2peak) from baseline to 12-wk follow-up (ΔV˙O2peak) in a post hoc analysis from the SMARTEX Heart Failure trial.

Methods: We studied 215 patients with heart failure with left ventricular ejection fraction (LVEF) ≤35%, and New York Heart Association (NYHA) classes II-III who were randomized to either supervised high-intensity interval training with exercise target intensity of 90%-95% of peak heart rate (HRpeak) or supervised moderate continuous training (MCT) with target intensity of 60%-70% of HRpeak, or who received a recommendation of regular exercise on their own. Predictors of ΔV˙O2peak were assessed in two models: a logistic regression model comparing highest and lowest tertiles (baseline parameters) and a multivariate linear regression model (test/training/clinical parameters).

High-Intensity Interval Training in Patients With Heart Failure With Reduced Ejection Fraction.

Background: Small studies have suggested that high-intensity interval training (HIIT) is superior to moderate continuous training (MCT) in reversing cardiac remodeling and increasing aerobic capacity in patients with heart failure with reduced ejection fraction. The present multicenter trial compared 12 weeks of supervised interventions of HIIT, MCT, or a recommendation of regular exercise (RRE).

Methods: Two hundred sixty-one patients with left ventricular ejection fraction ≤35% and New York Heart Association class II to III were randomly assigned to HIIT at 90% to 95% of maximal heart rate, MCT at 60% to 70% of maximal heart rate, or RRE.

Effects of different training modalities on circulating anabolic/catabolic markers in chronic heart failure.

Background: Muscle wasting in chronic heart failure (CHF) is a result of increased catabolism induced by proinflammatory cytokines like tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), and decreased anabolism due to alterations in the insulin-like growth factor 1 (IGF-1)/growth hormone (GH) axis. The goal of this study was to analyze the effects of 3 different training modalities (endurance training, strength training, and combined strength and endurance training [CT]) on circulating cytokines, IGF-1, and GH levels.

Methods: Patients with CHF (N = 45), NYHA class II-III, left ventricular ejection fraction < 35%, were randomly assigned to 1 of 3 training modalities.

[25 years of organized ambulatory heart sport in Luxembourg. The development of a sustained rehabilitation model].

After Second World War cardiovascular disease (CVD), especially coronary artery disease (CAD), turned out to be an epidemic in the western countries including the Grand-Duchy of Luxembourg, and accounted for nearly half of all deaths. A lot of strategies, among them treatment by physical activity, were developed to fight this challenge and, fortunately, a mortality regression of about 50 % could be achieved. Nowadays, eastern European countries and, more recently, China and India face an increasing CVD mortality.

Isokinetic versus one-repetition maximum strength assessment in chronic heart failure.

Purpose: Reduction in exercise capacity in patients with chronic heart failure (CHF) has been partially attributed to decreased muscle strength. Training studies reported important variations in strength increases during rehabilitation, ranging between 5% and 70% and depending on the measurement technique: isokinetic dynamometry or the one-repetition maximum (1RM) methods. Therefore, the question arises if both techniques assess the changes in muscle strength in a comparable way.

Reverse remodelling through exercise training is more pronounced in non-ischemic heart failure.

Purpose: Most training studies in patients with chronic heart failure (CHF) do not consider CHF aetiology in the interpretation of the results. About 60% of the patients in those studies have ischemic CHF (IHF) and 40% non-ischemic CHF (NHF). Recently, we conducted a randomized controlled trial to study three different training modalities in 60 patients with severe CHF, with a similar distribution of IHF and NHF patients.

[Ongoing medical problems in the anti-doping fight].

Over the last 20 years systematic doping has become a major threat for elite sport. So far, there is no clear information about the daily practice of doping. Repeated scandals and recent personal statements have added to our knowledge.

Is strength training the more efficient training modality in chronic heart failure?

Purpose: An open, randomized, controlled study was designed to study the effects of exclusive strength training (ST) in patients with severe chronic heart failure (CHF) in comparison with conventional endurance (ET) and combined ET-ST training (CT). The hypothesis was that ST would at least be equal to ET or CT, because peripheral muscle atrophy and weakness play a key role in exercise limitation in CHF patients.

Methods: Three groups of 15 patients underwent ST, ET, or CT during 40 sessions, three times a week, for 45 min.

[Prescription of physical activity in cardiology: classical and new indications (a review based on evidence based data)].

Evidence based data of physical activity in primary prevention of coronary heart disease are excellent. For secondary prevention these data still are acceptable. Although it is an important new target group for physical therapy, there are so far no favourable data for exclusive training therapy in children or adolescents presenting a syndrome of obesity, sedentary lifestyle and bad nutrition.

Strength/endurance training versus endurance training in congestive heart failure.

Purpose: The aim of this study was to compare the effects of endurance training alone (ET) with combined endurance and strength training (CT) on hemodynamic and strength parameters in patients with congestive heart failure (CHF).

Methods: Twenty male patients with CHF were randomized into one of two training regimens consisting of endurance training or a combination of endurance and resistance training. Group ET had 40-min interval cycle ergometer endurance training three times per week.
