Differences in the number of stented coronary arteries based on the seven traditional obesity parameters among patients with coronary artery diseases undergoing cardiac catheterization

Abstract

Background: Obesity has been correlated with certain sociodemographic and health variables of patients with coronary artery diseases (CADs). There are seven traditional obesity parameters, which have been used to measure obesity (body mass index [BMI], waist-to-height ratio [WHtR], waist-hip ratio [WHR], body adiposity index [BAI], body shape index [BSI], waist circumference [WC], and hip circumference [HC]). This study aimed to describe the differences in the number of stented coronary arteries based on the aforementioned seven traditional obesity parameters among patients with CADs undergoing cardiac catheterization. Method: A descriptive cross-sectional study was conducted among 220 hospitalized patients with CADs undergoing a cardiac catheterization. Data were analyzed using frequencies, percentages, bar graphs presentation, and receiver operating characteristics. Results: Receiver operating characteristic curve indicated that the best cut off point of WC is 95 cm in predicting number of stented coronary arteries with a sensitivity of 76% and a specificity of 68%. BMI had a high sensitivity with the number of stented coronary arteries. The sensitivity values of parameters ranged from 0.45 to 0.92 and the specificity values ranged from 0.25 to 0.68. All traditional obesity parameters except the BSI had a good ability to be highly associated with the number of stented coronary arteries. Conclusions: Healthcare providers, including nurses, should pay a high attention to these obesity parameters while caring of patients with CAD undergoing cardiac catheterization.
