Calculating and predicting the risk of disease plays an important role in preventive medicine. Today, some risk scores have been designed to estimate the risk of cardiovascular diseases (CVDs) by assessing different factors. Obesity is associated with an increased risk of cardiovascular disease, so we decided to calculate the possible risk of heart disease in obese Iranian people to suggest a more accurate calculator. In this cross-sectional study, we compared the data of 289 people from Framingham Risk Score and ASCVD Risk Score calculations who had been referred to Shariati Hospital Obesity Clinic, Tehran, Iran from 2016 to 2019. In the form of sub-goals, we examined other factors such as blood pressure and hepatic aminotransferases, etc. The mean age of participants was 51.20±7.58 years, 86.2% being women. Of the whole, 19.72%, 31.83%, 21.11%, and 27.34% were categorized as overweight, Obese I, II, and III, respectively. According to the ASCVD score 80.3%, 4.8%, and 14.9%, and according to the Framingham score 95.5%, 3.5%, and 1% were classified as low-risk, intermediate-risk, and high-risk. Moreover, a fair agreement was observed between the two-risk score in the whole (Kappa=0.236; P<0.001), overweight (Kappa=0.304; P=0.028), Obese I (Kappa=0.210; P=0.048), Obese II (Kappa=0.268; P=0.015), and obese III (Kappa=0.202; P=0.023). Despite its age limit, ASCVD has a higher risk of CVDs, causing statin care (which has a protective role for cardiovascular disease) to be given to a larger population.
