Aerobics restores protein quality in heart failure
Aerobic exercises such as running,
swimming or cycling may restore cardiac protein quality control system
in heart failure, a new study has found.
The study conducted in rats suggest that heart failure development is associated with disruption of cardiac protein quality control system and reinforce the importance of aerobic exercise training as a primary non-pharmacological therapy for treatment, researchers from Norwegian University of Science and Technology (NTNU) said.
Heart failure is a common endpoint for many cardiovascular diseases. This syndrome is characterised by reduced cardiac output that leads to dyspnea, exercise intolerance and later death, researchers said.
More than 20 million people worldwide are estimated to have heart failure and this situation will get worse since the prevalence of heart failure will rise as the mean age of the population increases, they said.
Though heart failure seems to be a multifactorial syndrome, a common point observed by several studies was the accumulation of "bad" (or misfolded) proteins in cardiac cells of both humans and animals with heart failure, researchers said.
Proteins are constituted by a sequence of amino acids that determines the protein "shape" (structure), which is critical for proteins function, they said.
During the evolution process, our cells developed a protein quality control system that refolds (when it is possible) or degrades misfolded proteins, allowing them to keep only the "good" (correctly folded) proteins.
In the study, researchers discovered that misfolded protein accumulation in a rat model of heart failure was related to disruption of the cardiac protein quality control system.
Since there is no pharmacology therapy targeting the protein quality control system, researchers studied whether aerobic exercise training, an efficient therapy for prevention and treatment of a variety of cardiovascular diseases, would reestablish the cardiac protein quality control system and improve cardiac function of heart failure rats.
They verified that aerobic exercise training restored the cardiac protein quality control system, which was related to reduced misfolded protein accumulation and improved cardiac function in heart failure animals.
The results suggest that heart failure development is associated with disruption of cardiac protein quality control system and reinforce the importance of aerobic exercise training as a primary non-pharmacological therapy for treatment of heart failure patients, researchers said.
The findings were published in the Journal of Cellular and Molecular Medicine.
