The relation between BMI with exercise test in individuals with cardiac ischemic pains

Background and Prevalence of over weight and obesity is increasing in the world. Those over weight are more susceptible to cardiovascular diseases than other individuals. Studies indicate that body fat distribution has a determining role in the identification of risk factors. Also, the relation between BMI, cardiac ischemic pains and exercise test condition in such patients, is in need further investigation. The aim of this study was to determine the relation between BMI with exercise tolerance test in patients with cardiac ischemic pains, who were referred to the Cardiac Center of Mazandaran Province, in Sari Township. In this case control study considering the BMI in ischemic patients, 65 were selected as case and 65 persons as control using Tread mill and according to Bruce Protocol, results and tolerance test time was recorded. Independent T test was used for comparison of quantitative indexes mean, while x2 test using SPSS soft ware was used for comparison of the ratio of persons with the qualitative features. Data indicated mean weight of 57.1 kg and height of 1.64m in the case group. Also, 58.5% had history of hyperlipidemia (Cholesterol higher than 200mg/dl) and 78.8% with history of blood sugar (higher than 120mg/dl (P<0.001). Even 63.6% had hypertension of 140/9o mm Hg. Our findings showed that BMI in the case and control groups were (26.95±3.94) and (25.95±3.49) respectively. Moreover, a significant relationship between high BMI with cardiac ischemic pains and exercise tolerance test (P<0.001) were demonstrated. Cardiac ischemic pains in individuals with high BMI is common. Exercise tolerance test as one of the non invasive and less expensive procedures, can be an indicator of cardiac ischemic disease.
