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.

The main outcomes broad the effect of simples and easy doccumented cardiovascular risk factors such as sex, race, age, familiar history of coronary artery disease, overweight or obesity, smoking, stress, and physical inactivity on electrocardiogram and hemodinamics abnormalities during and after exercise treadmill exercise test.

Inclusion Criteria:

• Subjects that can complete the treadmill exercise test with the Ellestad protocol with 6 minutes of recovery.

Exclusion Criteria:

• Use of remedies for blood pressure, glycemia, cholesterol, and serum lipids;
• Symptomatically subjects;
• Electrocardiogram that are not able to be interpreted;
• Blood pressure in rest state ≥180 mmHg and ≥110 mmHg, for systolic and diastolic, respectively.

Healthy and assymptomatically subjects who are visiting cardiologyst for routine.
