Cardiovascular Risk Factors on Electrocardiographically and Hemodynamics Responses to Treadmill Exercise Test

The goal of this observational cross-sectional study is to analyze the effect of cardiovascular risk factors in healthy and asymptomatic populations. The main questions it aims to answer are: * Does the combination of the presence of different risk factors increase the risk for abnormalities appearing on electrocardiograms, such as ischemia, arrhythmia, and hemodynamics effects during and at the peak of effort of treadmill exercise test? * What are the main differences observed in the recovery period? Participants will answer an anamnesis of risk factors such as sex, race, age, familiar history of coronary artery disease, overweight or obesity, smoking, stress, and physical activity practice and perform treadmill exercise test on Ellestad protocol. If there a comparison groups: Researchers will compare individuals with most risk factors with those without, to see the cardiovascular responses.
