    ABSTRACT: Vent-HeFT is a multicentre randomized trial designed to investigate the potential additive benefits of inspiratory muscle training (IMT) on aerobic training (AT) in patients with chronic heart failure (CHF). Forty-three CHF patients with a mean age of 58 ± 12 years, peak oxygen consumption (peak VO2 ) 17.9 ± 5 mL/kg/min, and LVEF 29.5 ± 5% were randomized to an AT/IMT group (n = 21) or to an AT/SHAM group (n = 22) in a 12-week exercise programme. AT involved 45 min of ergometer training at 70-80% of maximum heart rate, three times a week for both groups. In the AT/IMT group, IMT was performed at 60% of sustained maximal inspiratory pressure (SPImax ) while in the AT/SHAM group it was performed at 10% of SPImax , using a computer biofeedback trainer for 30 min, three times a week. At baseline and at 3 months, patients were evaluated for exercise capacity, lung function, inspiratory muscle strength (PImax ) and work capacity (SPImax ), quality of life (QoL), LVEF and LV diameter, dyspnoea, C-reactive protein (CRP), and NT-proBNP. IMT resulted in a significantly higher benefit in SPImax (P = 0.02), QoL (P = 0.002), dyspnoea (P = 0.004), CRP (P = 0.03), and NT-proBNP (P = 0.004). In both AT/IMT and AT/SHAM groups PImax (P < 0.001, P = 0.02), peak VO2 (P = 0.008, P = 0.04), and LVEF (P = 0.005, P = 0.002) improved significantly; however, without an additional benefit for either of the groups. This randomized multicentre study demonstrates that IMT combined with aerobic training provides additional benefits in functional and serum biomarkers in patients with moderate CHF. These findings advocate for application of IMT in cardiac rehabilitation programmes.

    ABSTRACT: Muscle resistance training is often combined with aerobic endurance training during rehabilitation of patients with coronary artery disease. However, the clinical effects of additional lower-extremity low-intensity muscle resistance training during early rehabilitation (within the first month after coronary revascularization) in patients with coronary artery disease remain unclear. Prospective randomized controlled trial. Sixty patients with coronary artery disease. Subjects were randomly assigned to early aerobic endurance training (n = 30) or combined aerobic endurance and resistance muscle training (n = 30). Subjects performed 18 (standard deviation 2) exercise sessions (at 65% VO(2peak), for 40 mins/session). In resistance muscle training, additional low-intensity (12-20 repetition maximum) resistance muscle exercises were performed. The following parameters were evaluated: exercise capacity, body composition, blood lipid profile, glycaemic control, blood endothelial progenitor cell and cytokine content, and muscle performance. A total of 47 patients with coronary artery disease completed the intervention. Total body lean tissue mass tended to increase with greater magnitude (p = 0.07), and blood high-density lipid cholesterol content increased with significantly greater magnitude in resistance muscle training (p < 0.05), compared with aerobic endurance training. Maximal exercise capacity, ventilatory threshold, and muscle performance increased, and steady-state exercise respiratory exchange ratio, and adipose tissue mass reduced significantly (p < 0.05), without differences between groups (p < 0.05). In early aerobic endurance training intervention in patients with coronary artery disease, additional low-intensity resistance muscle training contributes to a greater increase in blood high-density lipid cholesterol content, and tends to affect lean tissue mass.

    ABSTRACT: In cardiac rehabilitation, 40-60-min exercise training sessions are advised. However, because of the increasing coronary artery disease (CAD) prevalence and higher workload for cardiac rehabilitation centres, it remains unclear whether 40-min exercise training sessions are equally effective as 60-min exercise training sessions. Prospective randomized clinical trial. One hundred and thirty-four CAD patients were included in a 7-week rehabilitation programme. All patients exercised 3 days per week, at a heart rate corresponding to 65% of baseline peak oxygen uptake (VO2peak). Patients were randomized in two groups: 40 versus 60-min exercise training sessions. Changes of body anthropometrics, resting haemodynamics, exercise capacity and ventilatory threshold, blood plasma lipid profile and C-reactive protein level were assessed. As a result of rehabilitation, exercise capacity, ventilatory threshold, and blood plasma lipid profile improved significantly in the total population (P<0.05), without differences between subgroups (P>0.05). Body weight and waist circumference decreased significantly in total population (P<0.01), but with a greater magnitude in the 40 versus 60-min exercise session group (P<0.05). In the early rehabilitation of CAD patients, 40-min exercise training sessions seem to be at least as effective for improving body anthropometrics, blood plasma lipid profile and exercise capacity, as compared with 60-min exercise training sessions.
