Effects of High-Intensity Interval Exercise Training on Skeletal Myopathy of Chronic Heart Failure.

Background: It remains controversial which type of exercise elicits optimum adaptations on skeletal myopathy of heart failure (HF). Our aim was to evaluate the effect of high-intensity interval training (HIIT), with or without the addition of strength training, on skeletal muscle of HF patients.

Methods And Results: Thirteen male HF patients (age 51 ± 13 years, body mass index 27 ± 4 kg/m) participated in either an HIIT (AER) or an HIIT combined with strength training (COM) 3-month program.

Long-term outcomes of primary systemic light chain (AL) amyloidosis in patients treated upfront with bortezomib or lenalidomide and the importance of risk adapted strategies.

Bortezomib and lenalidomide are increasingly used in patients with AL amyloidosis, but long term data on their use as primary therapy in AL amyloidosis are lacking while early mortality remains significant. Thus, we analyzed the long term outcomes of 85 consecutive unselected patients, which received primary therapy with bortezomib or lenalidomide and we prospectively evaluated a risk adapted strategy based on bortezomib/dexamethasone to reduce early mortality. Twenty-six patients received full-dose bortezomib/dexamethasone, 36 patients lenalidomide with oral cyclophosphamide and low-dose dexamethasone and 23 patients received bortezomib/dexamethasone at a dose and schedule adjusted to the risk of early death.

The challenge of treating congestion in advanced heart failure.

Volume overload is a common manifestation of heart failure decompensation. Interaction between impaired renal and heart function constitutes an important pathophysiologic mechanism that leads to congestion. In addition to improving symptoms and volume status, reduction of rehospitalization rates, maintenance of renal function and improvement of survival are all important goals of every therapeutic strategy.
