This study aims to study the efficiency of the Waist-to-Height Ratio (WHtR) for determining coronary artery disease. It compares\nthe frequency of abnormal WHtR, as a proxy for abdominal obesity, to that of body mass index (BMI) and waist circumference\n(WC). It also relates the findings to other cardiometabolic risk factors in University Hospital patients. A cross-sectional study\ndesign was used, where a sample of 200 patients (142 males and 58 females) who attended the adult cardiac clinic were purposively\nincluded. BMI, WC, and WHtR were measured, where frequencies of WHtR were compared to those of BMI and WC. The\nfindings were related to the history of coronary artery disease (CAD) and history of cardiometabolic risk factors, including\ndiabetes mellitus (DM), hypertension (HTN), and hyperlipidemia. Majority of the male patients were older, taller, and had a lower\nBMI value. It also showed that the prevalence of dyslipidemia and CAD was higher in male patients. No significant difference\nbetween both genders was noticed for weight, WC, WHtR, hypertension, or DM. BMI was least associated with high-risk cardiac\npopulation in both males and females (39.4% and 60.3%), followed by WC (84.5% and 96.6%, respectively). WHtR showed the\nhighest association with gender (male 98.6% and females 98.3%). These findings were noticed in patients with all risk factors.\nWHtR is superior to BMI and WC for determining the elevated risk of diabetes, hypertension, dyslipidemia, and CAD in a single\nuniversity institute. The role of WHtR in both normal and diseased Saudi population should be delineated.
