Study on the Relation Between BMI and Degree of Coronary Artery Obstruction

Obesity is introduced as a known risk factor of coronary artery disease (CAD) by the American heart association. BMI is an index used for the evaluation of body weight. Despite presence of the relationship between BMI and occurrence of coronary artery disease, yet, no relationship has been found between the degrees of coronary artery obstruction and BMI which is the main issue of this research. In order to determine body mass index at different stages of coronary artery obstruction, this study was done in descriptive method on 215 patients referring to angiography unit of Imam Khomeini hospital and BMI was measured at different stages of coronary artery obstruction. Questionnaire containing questions on demographic features and risk factors of coronary artery disease was filled. The obtained data were analyzed using SPSS software and descriptive analysis tests. Of 215 patients under study, mean age of 55 years (83 men and 132 women), all of them suffered from coronary artery problem ranging from one vessel to complete obstruction. Severity of coronary artery obstruction and the number of vessels involved had direct relationship with the increase in the rate of BMI. There was significant relationship between degree of BMI and observation of severity in obstruction during angiography (p<0.005).
