Introduction
The main goal of cardiovascular rehabilitation is to improve cardiorespiratory fitness using aerobic exercise (AE). The general recommendation for the practice of physical exercise, according to the Brazilian Society of Cardiology, is 150 minutes per week divided into 3 to 5 weekly sessions. The appropriate practice of physical exercise aims to reduce blood pressure, risk of cardiovascular events and risk of mortality in cardiovascular patients.,
The cardiopulmonary exercise test (CPET) is the reference test to assess cardiorespiratory function and prescribe AE intensity. CPET analysis allows identification of the most adequate and recommended variables, such as maximal oxygen uptake, workload, maximal heart rate (HR), HR reserve, and ventilatory thresholds (VTs).– However, this test still has limited access, especially in developing countries, due to high costs, the need for highly trained professionals, and complex analyses.,
