Abstract
IntroductionMorbid obesity is a condition of multifactorial origin with a high prevalence worldwide, and has a direct relationship with other illnesses. ObjectiveTo analyse the cardiovascular responses of morbid obese women using a maximum stress test for stratifying risk and the prescribing of exercise. MethodThe study included 13 patients with Grade III obesity. All were women between 20 and 40 years of age. Their arms were subjected to an ergospirometry test on the cycle ergometry in order to check and analyse heart rate, blood pressure, and the double product. ResultsThe patients had a mean age of 34.7±5.1 years, and a mean body mass index of 46.5±3.8kg/m2. A maximum heart rate of 168.2±14.6 bpm was achieved, with no hypertensive response to the stress, and blood pressure of 171.1±22.2mm Hg (systolic) x 87.5±4.2mm Hg (diastolic). The maximum double product found was 28,662.2 ±3,644.1mm Hg.bpm. ConclusionIn the results of this study is observed reduction of heart rate, blood pressure, and the double cardiac product, compatible with the expected effort for the test.
