Introduction: Obesity has been considered a risk factor for acute coronary events. The main factors to develop this type of diseases are present in most of the patients subjected to bariatric surgery. Objective: To assess the cardiovascular risk of patients subjected to bariatric surgery preoperatively and at 2-years follow-up. Setting: General Hospital ''Dr. Manuel Gea González''. Design: Retrospective, longitudinal, observational, and comparative study. Patients and methods: Patients from the bariatric surgery clinic, operated with the gastric bypass technique, calculating the cardiovascular risk preoperatively and at 2-year follow-up. Results: The study included 64 patients (13 men and 51 women). Average age of men was 42 years, their average body mass index was 49.44 kg/m², preoperative cardiovascular risk score was 5.15 (2-9). At 2-year follow-up, their BMI diminished to 36.23 kg/m², the cardiovascular risk score was 2.38 (0-5). In women, average age was of 36 years, their body mass index before surgery was of 45.32 kg/m², the cardiovascular risk score was 4.3 (-10 a 13). At 2-year follow-up, their average body mass index reduced to 28.64 kg/m² (20.1-42.1), and the cardiovascular risk score was -4.1 (-11 to 8). Conclusion: Bariatric surgery has not only been demonstrated as an efficacious and safe method to reduce body weight in patients with morbid obesity but also to diminish the cardiovascular risk depicted by these patients.
