Retrospective Study of the Association of Statins on Cardiorespiratory Fitness and Exercise Adaptation: Database of the Cardiovascular Rehabilitation and Exercise Physiology Department of Heart Institute (InCor)

CardioRehab Bank Study

Statins are part of one of the largest groups of drugs prescribed worldwide used in the treatment of dyslipidemia. Despite the good therapeutic results of statins and their good tolerance on the part of patients, some adverse effects may occur during treatment. In skeletal muscle, statins can lead to mitochondrial dysfunction characterized by decreased adenosine triphosphate production, decreased oxidative phosphorylation capacity, increased concentration of reactive oxygen species, and decreased mitochondrial biogenesis. Cardiorespiratory fitness is a physiological indicator that corresponds to the integration of the cardiovascular, pulmonary, muscular, and cellular (mitochondria) systems in capturing, transporting and using oxygen, commonly expressed as the maximum oxygen consumption. Several studies show a strong association of lower cardiorespiratory capacity with an increased risk of mortality from cardiovascular disease and mortality from all causes. Combining the use of statins with lifestyle changes has been suggested in many medical guidelines. Physical exercise plays a fundamental role in improving cardiorespiratory fitness and controlling dyslipidemia. However, some studies suggest that the association of statin with physical training can negatively influence the adaptation and improvement of cardiorespiratory capacity. On the other hand, some studies show that the combination of statin and physical exercise does not negatively interfere with the maximum oxygen consumption. To determine the impact of statins on cardiorespiratory fitness and adaptation to physical exercise, the investigators will use the database of the Cardiovascular Rehabilitation and Exercise Physiology Department at Heart Institute (Sao Paulo, Brazil), which currently has 33,804 maximal cardiopulmonary exercise tests. This large database, which is the gold standard of cardiorespiratory capacity (maximum oxygen consumption), will be used retrospectively with relevant information and a huge number of participants. Therefore, the aim of this study will be to explore a large database to assess the effect of the use of statins and their relationship with cardiorespiratory capacity in physically active and sedentary individuals (with and without heart failure).
