Introduction:

Obesity is a multisystemic disease and a coronary risk factor that is frequently associated with others, such as high blood pressure, diabetes and dyslipidemia. These all increase the risk of heart disease.

Objective:

We aimed to determine the cardiovascular response of obese patients during a stress test.

Methods:

An observational, descriptive and cross-sectional study was conducted with 67 obese participants (45 women and 22 men) aged 35±12.6 years on average. To develop our research, we analyzed anthropometric variables and vital signs. The Borg scale, a cardiovascular risk factor interview and a Bruce treadmill stress test protocol were also applied.

Results:

The main cardiovascular risk factors found were sedentary lifestyle (100%) and family history of disease (76%). An average maximum heart rate of 172.82±18.81 beats per minute was obtained, which was higher in women (173.9±17.5 vs. 168.9±22.1). It was found to be higher in patients with less than four cardiovascular risk factors (179.4±17.7 vs. 167.1±18.6) when associated with cardiovascular risk factors.

Conclusions:

A decrease in cardiovascular response was found in relation to the expected test effort. The greater the number of cardiovascular risk factors, the lower the maximum heart rate achieved.
